I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:

&gt; This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.3.v201404151837-1123206. Please update ADT to the latest version.

No updates were found with **&quot;Check for updates&quot;**. If I try **&quot;Install new software&quot;**, I can see version 23, but I can&#39;t upgrade due to the following error:

After download of the last ADT from the web site, it seems there&#39;s another problem.

With SDK Tools rev. 23 proguard is not installed, the folder SDK `dir/tools/proguard` is missing, and other tools are missing. This version contains several bugs.


Update Eclipse with Android development tools v. 23

Since updating to `ADT` 14 I can no longer build my project. It was building fine prior to updating. 

The error:

    [2011-10-23 16:23:29 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;
    [2011-10-23 16:23:29 - myProj] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;

Similar issues have been reported and I have tried the suggestions there including

 - Restarting `Eclipse`.
 - Cleaning the project and rebuild - Disable &quot;Project-&gt;Build Automatically&quot; option, then &quot;Clean&quot; and &quot;Build&quot; project, then try to run. reset &quot;Build Automatically&quot; option to On
 - Re-installing the `Android` Developer Tools
 - Re-installing Eclipse (updated to the latest version 3.7.1)
 - Created a new project importing from the file system
 - Created a new project from subversion.

Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;

Since AVD tools 16 I&#39;m getting this warning:

    Replace &quot;...&quot; with ellipsis character (..., &amp;#8230;) ?

in my strings.xml

at this line
   
     &lt;string name=&quot;searching&quot;&gt;Searching...&lt;/string&gt;

How do I replace `...`? Is it just literally `&amp;#8230;`?

Could someone explain this encoding?

Android Replace &quot;...&quot; with ellipsis character

I installed the latest version of the SDK (r21) and ADT 21.0.0. I tried simple code, and it works well, but now I get a warning in [LogCat][1] that did not appear in the previous versions:

&gt; Unexpected value from nativeGetEnabledTags: 0

I googled it, and I found *[Issue 39723: Emulator spams LogCat with &quot;Unexpected value from nativeGetEnabledTags: 0&quot; message][2]*.

What does it mean?

  [1]: https://sites.google.com/site/androidhowto/how-to-1/save-logcat-to-a-text-file
  [2]: http://code.google.com/p/android/issues/detail?id=39723


Unexpected value from nativeGetEnabledTags: 0

Since the [**new ADT preview version (version 21)**][1], they have a new lint warning that tells me the next thing on the manifest file (in the application tag):

&gt; Should explicitly set android:allowBackup to true or false (it&#39;s true by default, and that can have some security implications for the application&#39;s data)

In the [**official website**][1], they&#39;ve written:

&gt; A couple of new checks: you must explicitly decide whether your app allows backups, and a label check. There&#39;s a new command line flag for setting the library path. Many improvements to the incremental lint analysis while editing.

What is this warning? What is the backup feature, and how do I use it?

Also, why does the warning tell me it has security implications? What are the disadvantages and advantages of disabling this feature?

-------------------------------------------------------------------------------

There are two concepts of backup for the manifest:

 - &quot;android:**allowBackup**&quot; allows to backup and restore via adb, as shown [**here**][2]:

&gt; Whether to allow the application to participate in the backup and
&gt; restore infrastructure. If this attribute is set to false, no backup
&gt; or restore of the application will ever be performed, even by a
&gt; full-system backup that would otherwise cause all application data to
&gt; be saved via adb. The default value of this attribute is true.

This is considered a security issue because people could backup your app via [ADB][3] and then get private data of your app into their PC.

However, I think it&#39;s not that of a problem, since most users don&#39;t know what adb is, and if they do, they will also know how to root the device. ADB functions would only work if the device has the debugging feature enabled, and this needs the user to enable it.

So, only users that connect their devices to the PC and enable the debugging feature would be affected. If they have a malicious app on their PC that uses the ADB tools, this could be problematic since the app could read the private storage data.

I think Google should just add a feature that is disabled by default, in the developer category, to allow backup&amp;restore of apps via ADB.

 - &quot;android:**backupAgent**&quot; allows to use the backup and restore feature of the cloud, as shown [**here**][4] and [**here**][5]:

&gt; The name of the class that implement&#39;s the application&#39;s backup agent,
&gt; a subclass of BackupAgent. The attribute value should be a fully
&gt; qualified class name (such as, &quot;com.example.project.MyBackupAgent&quot;).
&gt; However, as a shorthand, if the first character of the name is a
&gt; period (for example, &quot;.MyBackupAgent&quot;), it is appended to the package
&gt; name specified in the &lt;manifest&gt; element. There is no default. The
&gt; name must be specified.

This isn&#39;t a security issue.

New version of ADT r17 plugin for Eclipse added feature to automatically setup JAR dependencies. Any .jar files in the /libs folder are added to the build configuration now. Unfortunately Android Dependencies classpath container is non modifiable.

How to attach javadoc or sources to jars in libs folder?

I have a rather big Android App project that is referencing several library projects. Everything was fine until i upgraded the eclipse ADT plugin to the newest version (v22). I also upgraded the SDK of course. I do not see any compile errors in eclipse, but when i run the project on the phone i get a NoClassDefFoundError.

    java.lang.NoClassDefFoundError: org.acra.ACRA
    ....

The arca library is included in one of the referenced library project (in the libs folder) and i can see it in the &quot;Android Private Libraries&quot; in the package explorer, also as i said, no compile errors. The project runs fine on everyone else&#39;s computer that did not upgrade ADT.

I have already tried a whole bunch of stuff including but not limited to:

 - re-install the android SDK
 - download a fresh ADT bundle
 - delete all my code an get it again from git
 - copy the library in question to the app project
 - comment out the code that uses this library - i just get the same error for the next library

all without any success, so i&#39;m getting really desperate here.

I would be really happy if anyone could give me a hint on how to solve that problem.

Libraries do not get added to APK anymore after upgrade to ADT 22

I am trying to, somewhat clone the design of an activity [from a set of slides on Android UI design][1]. However I am having a problem with a very simple task.

I have created the layout as shown in the image, and the header is a `TextView` in a `RelativeLayout`. Now I wish to change the background colour of the `RelativeLayout`, however I cannot seem to figure out how.

I know I can set the `android:background` property in the `RelativeLayout` tag in the XML file, but what do I set it to? I want to define a new colour that I can use in multiple places. Is it a `drawable` or a `string`?

Additionally I would expect there to be a very simple way to this from within the Eclipse Android UI designer that I must be missing?


I am a bit frustrated currently, as this should be an activity that is performed with a few clicks at maximum. So any help is very appreciated. :)

I am starting to develop Android applications. Which version of Eclipse should I use?

I see there are 11 versions. I am confused with these:

 1. Eclipse IDE for Java Developers
 2. Eclipse Classic 3.6.1
 3. Eclipse IDE for Java EE Developers
 4. Pulsar for Mobile Developers


Which Eclipse version should I use for an Android app?

Every time I try to export an APK from Eclipse (tried Juno and Indigo) on Mac, eclipse crashes after a few seconds

This used to work fine on my current setup.

Running the app straight (debug mode) on my phone works fine.

The error from the console is:

    Invalid memory access of location 0x10073f113 rip=0x101f656f7
    Bus error: 10

I&#39;m using Mac OS X 10.7.4 on a ~2010 MacBook Pro, with the following java:

    java version &quot;1.6.0_33&quot;
    Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
    Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)

I&#39;m using ADT 20.

I&#39;ve tried reinstalling Eclipse and the Android SDK, and re-downloading ADT.

The Eclipse error view doesn&#39;t show anything


Any ideas of different methods I can try, or other ways to investigate what&#39;s going wrong?

Cheers

Update: For anyone coming along post-2014, you should be using &lt;a href=&quot;https://developer.android.com/sdk/installing/studio.html&quot;&gt;Android Studio&lt;/a&gt;, which doesn&#39;t have this problem.

Exporting APK from eclipse (ADT) silently crashes

I have tried to update my Eclipse. Currently I have till 2.2 Android SDK in my Eclipse. Yesterday I have updated my Eclipse like this:

Eclipse -&gt; window -&gt; Android SDK Manager -&gt; I have checked two check-boxes from list. Tools -&gt; Android SDK Tools and Android SDK Platform Tools.

I have posted here some last lines of the message which I get from downloading and installing:

But after all this after I have closed Eclipse and again wanted to start, it throw the error:

&gt; This Android SDK requires Android Developer Toolkit version 20.0.0 or above. Current version is 16.0.0.v201203301601-306762. Please update ADT to the latest version.

In preferences I received this error:

How can I update my ADT in Eclipse?

In the newest version of ADT (r17) a generated constant was added `BuildConfig.DEBUG` that is set according to the build type. The problem I have is that it is never set to false, I expected it to change when doing &quot;Android Tools -&gt; Export Signed Application Package&quot; but it hasn&#39;t for me. 

So how do I change the build type?

&gt; Added a feature that allows you to run some code only in debug mode.
&gt; Builds now generate a class called BuildConfig containing a DEBUG
&gt; constant that is automatically set according to your build type. You
&gt; can check the (BuildConfig.DEBUG) constant in your code to run
&gt; debug-only functions

When does ADT set BuildConfig.DEBUG to false?

I have installed adt version 22.6.1 already 2 days ago. It was working fine. Suddenly, When I open eclipse today, it keeps showing me following error:

*This Android SDK requires Android Developer Toolkit version 22.6.1 or above. Current version is 22.2.1.v201309180102-833290.  Please update ADT to the latest version.*

Here is screenshot of my eclipse&#39;s Android SDK Manager : 
![enter image description here][1]


I tried with following steps to resolve my issue as discussed in this [**Link**](https://code.google.com/p/android/issues/detail?id=67325)

 1. Help | Install new software 
 2. Select the ADT update site (there are two, one with `http://` and one with `https://`. If one doesn&#39;t work, try the other. 
 3. Select the developer tools section and press next. 
 4. You should see a dialog that says **This software is already installed, an update will be performed instead**. Clicking **OK** will lead to 22.6.1 being installed.

But unfortunately it didn&#39;t work for me. 

Here is a screenshot I am attaching which shows the error I am getting while updating the tools.

![enter image description here][2]

How can I get rid of it?

Error: This Android SDK requires Android Developer Toolkit version 22.6.1 or above

This seems like a trivial task, but I can&#39;t find an option to cleanly de-install the ADT from my Eclipse installation.
Of course, I could just delete the folder of the SDK, but this just throws errors when starting up Eclipse the next time. The reason I&#39;m asking is because my old ADT keeps throwing a wierd error (Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list.xml, reason: File not found) and I need a complete, fresh re-install.

Uninstalling Android ADT

Attempting to do some work on an Android project I haven&#39;t worked on for a couple of months, yet every time I attempt to build the project Eclipse throws up a dialog saying:

    &#39;Building workspace&#39; has encountered a problem

    Errors occurred during the build.
    Errors running builder &#39;Android Pre Compiler&#39; on project &#39;XXX&#39;
    java.lang.NullPointerException

I&#39;m running Eclipse on a Mac with an Android project build target 4.0.3 (API Level 15) and I&#39;ve the following versions of things installed

 - Eclipse - 3.7.2
 - Android Development Tools - 21.0.1
 - Android SDK - up to 17 

I&#39;ve already tried a few things, like starting a whole new workspace, installing this &#39;Subversive SVN JDT Ignore Extensions&#39;, upgrading everything, making sure I don&#39;t have any files without extensions in my source folder (or anywhere else), ensuring my Java compiler is 1.6 and switching it off and on again.

**EDIT**

Here&#39;s the stack trace from the Eclipse error log for this problem:

    java.lang.NullPointerException

&lt;/pre&gt;

**ANOTHER EDIT**

OK, so more searching led me to [this page]( http://code.google.com/p/android/issues/detail?id=43057), which suggests that this issue is definitely related to the presence of files without an extension in my project - however I don&#39;t know which file and for the life of me I can&#39;t find any in that project! 

I&#39;d even be happy if someone could explain what this error means and how I might get more debug info about the underlying error.

Eclipse / Android : &quot;Errors running builder &#39;Android Pre Compiler&#39; on project...&quot;

This problem sounds similar to a [few][1] [others][2], except in my case the OK button is not grey-ed out. But for those who would rather not click the links...

Trying to create or edit an AVD from within Eclipse, after entering my settings, the &quot;OK&quot; button seems to be &quot;clickable&quot;, but when I click it absolutely nothing happens. ![clickable but useless][3]

I&#39;ve made sure I have the appropriate system images installed, and that the target platform matches the API being used. Clearly a CPU has been chosen, skin set, etc... all the things that would make the OK button greyed out, which it&#39;s not.

I can create/edit AVDs if I run the AVD manager from *outside* eclipse, so this isn&#39;t the end of the world, but I feel there&#39;s a solution to this particular problem and I want to help solve it.

I&#39;ve tried running eclipse as an administrator (that&#39;s what stopped the AVD manager from crashing outside of eclipse). I&#39;ve tried just waiting around, or clicking multiple times. Looking at the Task Manager, no new processes begin when I click OK, nor does eclipse&#39;s CPU or RAM usage increase at all. The &quot;Edit Android Virtual Device&quot; window doesn&#39;t even go away.

Any clues?

I am trying to add the add SDK Platform 1.6 to an existing Install of 2.2, with the help of [this thread][1].

As suggested, I ran &lt;kbd&gt;Help&lt;/kbd&gt; → &lt;kbd&gt;Check for Updates&lt;/kbd&gt; which found and installed the following:

      + Android DDMS              8.0.1.v201012062107-82219
      + Android Development Tools 8.0.1.v201012062107-82219

It prompted for restarting Eclipse and when it restarted it gave me the following error message:

    &quot;SDK Platform Tools component is missing!
    Please use the SDK Manager to install it.&quot;

Huh? Why? I still have the SDK Platform Tools on C:\android-sdk-windows that was working perfectly before I did this &quot;upgrade&quot;.

What do I need to have both 2.2 and 1.6 supported in my development environment?

I&#39;m trying to figure out how to debug applications directly on my phone (HTC Desire).

I&#39;ve installed the USB driver that came with the phone and the phone is listed when using &quot;adb devices&quot;.

How do I configure eclipse/ADT to launch on the phone instead of launching the emulator/virtual device?

Eclipse Indigo - Cannot install Android ADT Plugin

Today I upgraded to Android SDK 2.3 and I also upgraded the Eclipse Plugin Androi Developer Tools 8.0 (from 0.9.9). I also upgraded my Java Development Kit to 1.6_22.

Now in Eclipse I get **many errors** in all my Android projects.

The error messages are like:

&gt;The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files.

How can I fix this so I can use my Android projects again?

In the Build Path for these projects, I don&#39;t have any references to an `android.jar` but a message:

&gt; Unable to get system library for project

&quot;Unable to get system library for project&quot; after I upgraded to Android SDK 2.3 and ADT 8.0

I am currently trying to develop an application for Android in the latest release of Eclipse. When I try to build and run, the following comes up: 


    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] The connection to adb is down, and a severe error has occured.
    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] You must restart adb and Eclipse.
    [2011-02-17 17:08:03 - &lt;ProgramName&gt;] Please ensure that adb is correctly located at &#39;C:\&lt;sdk-directory&gt;s\platform-tools\adb.exe&#39; and can be executed.

Now, I have updated the ADT plugin, I have the latest version of the Android SDK; adb.exe is, in fact, in the platform-tools directory and can be executed. I&#39;ve tried everything I found on Google:

 - I tried adb kill-server and adb start-server
 - I tried to run it with an without an emulator started
 - I have the given directory in my PATH (I tried with just the platform-tools in the path and I tried with having both platform-tools and tools in my PATH).

Notes: I am running Windows 7. Also, I have previously tested apps in Eclipse. This error is new to me since upgrading the SDK. 



The connection to adb is down, and a severe error has occurred

I&#39;m developing for Android with Eclipse, and all was working well until yesterday. I used Ninite to update all my stuff, including JREs and everything (pro tip: do not do that), and it restarted my computer without asking in the middle of editing my workspace. 

This caused all kinds of filthy problems, but now it all works, except for Android. I&#39;ve updated Android SDK and the eclipse ADT, then when I try to tell Eclipse the SDK location, it gives this error:

&gt; This Android SDK requires Android Developer Toolkit version 14.0.0 or
&gt; above.  Current version is 12.0.0.v201106281929-138431.  Please update
&gt; ADT to the latest version.

Now, this is an outright lie. My ADT is version 14.0.something. I&#39;ve tried Help&gt;Check for updates, it says there are no updates. I&#39;ve tried Help&gt;Install new software...&gt;Available Software Sites and removing the ADT repo, then reinstalling ADT, and it says it failed because I already have version 14.0.whatever. 

How do I convince eclipse that my ADT is up to date??

Eclipse: won&#39;t let me use Android SDK, wrongly claims my ADT is out of date

I&#39;ve recently updated Android SDK &amp; Eclipse ADT plugin to latest version. Now when i try to run a pre-existing Android project, the LogCat shows a `ClassNotFoundException`.

I tried to create a new device but the problem still exists.

I just prepare small update for my android app, but I get this strange bug when I try to build my app (in debug mode). It will be great if someone smarter could look at this to figure out what might been wrong. I was cleaning/rebuild/fix project properties, but with no results. I have no clues what is going on :(. Maybe something similar happen to anyone here?
If this can help I use following libraries: adMob(4.1.1), openfeint and libgdx.

After installing the new ADT (22.3.0.v201310242005-887826) which supports Android 4.4 (KitKat), I keep getting the error as shown here:

![Enter image description here][1]

&gt; An internal error has occurred

In the list of errors, I see multiple items of &quot;RenderPreview&quot;, and when I click on any of them, I see:

&gt; An internal error has occurred. After scene creation, #init() must be
&gt; called

When testing the new ADT on another computer, I can&#39;t see this error appearing there. This is very weird.

Why do I get those errors, and what can I do to fix it?

ADT 22.3 (android 4.4) - getting error &quot;After scene creation, #init() must be called&quot;

I&#39;m working with Eclipse on Windows 7, x64. I&#39;m getting an error when running ADT bundle of android development:

&gt;   Error: Error parsing the AVDs  
&gt;   Unable to get the Android SDK home directory.  
&gt;   Make sure the environment variable ANDROID_SDK_HOME is set up.

I know what the issue is. Is it because it is linked to a wrong directory C:users:????

How do I set this environment variable android_sdk_home to the proper directory?



How do I set ANDROID_SDK_HOME environment variable?

I have 7 devices plugged into my development machine.

Normally I do `adb install &lt;path to apk&gt;` and can install to just a single device.

Now I would like to install my apk on all of my 7 connected devices. How can I do this in a single command? I&#39;d like to run a script perhaps.

How can I adb install an apk to multiple connected devices?

I just updated my Android SDK Tools to version 21.1. Unfortunately this is causing an error when I load the Android Developer Toolkit:

&gt; The Android SDK requires Android Developer Toolkit version 21.1.0 or above.
&gt; 
&gt; Current version is 21.0.1.2012-12-6-2-58.
&gt;
&gt; Please update ADT to the latest version.

When I upgraded the SDK I was warned that I might need to upgrade ADT. I tried to do so by going to Help &gt; Check for Updates. Unfortunately this returns a message that &quot;No updates were found.&quot;

In case I&#39;ve missed something here&#39;s a screenshot of my Android SDK Manager:

![Android SDK Manager][3]

Am I missing an install package? Do I need to go about updating ADT (Eclipse) another way? Should I just download a new copy of ADT?

When I load ADT why do I receive the error &quot;The Android SDK requires Android Developer Toolkit version XX.X.X or above?&quot;

So, seeing that the new Android L is out, I said I should give it a try. I installed the new ADT update from SDK tools and then from the updates. After Eclipse restart, I get the error that Android Dependencies failed to load because \android-sdk\tools\support\annotations.jar cannot be found. 

I checked the folder and it does not have the file.

Well, I said to myself that maybe the ADT update didn&#39;t go well so seeing that the new eclipse 4.4 is out I thought I could do a fresh install. So downloaded eclipse 4.4, installed the ADT tools and android sdk... and I get the same error.

Any ideas on how to fix this ?

Fail to find annotations.jar after updating to ADT 23

Recently I&#39;ve encountered following error :

![screenshot of dialog][1]


The strangest thing is that I&#39;ve just updated some package from sdk via working eclipse. There was no information or warning that after this update current adt will crash. I&#39;ve checked latest updates and can&#39;t find new adt even on google&#39;s page. Even new adb contain old adt.

From [http://developer.android.com/tools/sdk/tools-notes.html][2]:

&gt; Dependencies: Android SDK Platform-tools revision 18 or later. If you
&gt; are developing in Eclipse with ADT, note that this version of SDK
&gt; Tools is designed for use with ADT 22.6.1 and later. If you haven&#39;t
&gt; already, update your ADT Plugin to 22.6.1.

The only solution is to download new standalone eclipse and external plugin for it?
Does the android studio face the same problems?
