For some reason ADT (Eclipse) won&#39;t pick up on the fact that it does in fact need to be updated. Since the built in tools for updating are failing you you&#39;ll have to work around them. On the Help menu instead of selecting Check for Updates instead pick Install New Software (so Help &gt; Install New Software).

On the Available Software screen in the Work With dropdown provide:&lt;br /&gt;https://dl-ssl.google.com/android/eclipse/ if it&#39;s not already available. You should see a list of options including Developer Tools. Check everything that you want to update. In the list of checkboxes below uncheck &quot;Contact all update sites during install to find required software.&quot;

![Install New Software][1]

Click Next and follow the remaining onscreen prompts. You may be warned that instead of an install an update will be performed. This is okay. Once the operation is complete you will no longer receive the &quot;The Android SDK requires Android Developer Toolkit verxion 21.1.0 or above&quot; error when you load ADT.

When return value is not of interest, is there any (even irrelevant in practice) difference between [`AtomicInteger.getAndIncrement()`][1] and [`AtomicInteger.incrementAndGet()`][2] methods, when return value is ignored?

I&#39;m thinking of differences like which would be more idiomatic, as well as which would put less load in CPU caches getting synchronized, or anything else really, anything to help decide which one to use more rationally than tossing a coin.

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; 
&gt; Current version is 21.0.1.2012-12-6-2-58.

&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;

I want that the notification will be closed after the user is clicking on it. I saw that everybody saying to use flags, but I can&#39;t find the flags anywhere because I&#39;m using NotificationCompat.Builder class and not Notification class. Someone have any idea how to make the notification remove by her self?  
Here is my code when I&#39;m setting the notification: 

    NotificationCompat.Builder mBuilder =
    	        new NotificationCompat.Builder(this)
    	        .setSmallIcon(R.drawable.ic_launcher)
    	        .setContentTitle(&quot;New Question&quot;)
    	        .setContentText(&quot;&quot; + QuestionData.getAuthor().getUserName() + &quot;: &quot; + QuestionData.getQuestion() + &quot;&quot;);
				
    	Intent openHomePageActivity = new Intent(&quot;com.example.ihelp.HOMEPAGEACTIVITY&quot;);
    	TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    	stackBuilder.addNextIntent(openHomePageActivity);
    	
    	PendingIntent resultPendingIntent =
    	        stackBuilder.getPendingIntent(
    	            0,
    	            PendingIntent.FLAG_UPDATE_CURRENT
    	        );
    	mBuilder.setContentIntent(resultPendingIntent);
    	NotificationManager mNotificationManager =
    	    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);    	
    	
    	mNotificationManager.notify(0, mBuilder.build());

How to add (vertical) divider to a horizontal LinearLayout?

I know this question is pretty general but I haven&#39;t found any hints on why this error may show up. What are possible causes of seeing *initalizationError* in Eclipse window? I get no useful information just a long and useless failure trace (not included here). 


I am using JUnit 4.11

I have written the following code - just to see if it works:

    package test;

    import static org.junit.Assert.*;

    import org.junit.AfterClass;
    import org.junit.BeforeClass;
    import org.junit.Test;

    public class SimpleTest {

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
	}

	@AfterClass
	public static void tearDownAfterClass() throws Exception {
	}

	@Test
	public void test() {
		assertEquals(15, 15);
	}

    }

**Edit:** Sorry In Eclipse window it&#39;s called actually a &quot;Failure trace&quot;:

Eclipse JUnit - possible causes of seeing &quot;initializationError&quot; in Eclipse window

Some say I need to do that in Run Configurations for my application. When I open that window, could you please tell me how to set the right argument and the amount of memory? Say how to set 2GB or 1.5GB?

Whenever I start up Eclipse Juno, it gives me an error saying:

&gt; An error had occured. Please see the log file:

Some websites say to uninstall jdk and install it back again. I did that, but it didn&#39;t work. I think it was because on their website, the error is happening IN the workspace. Mine is on the program files folder, which is in the computer.

It happened after updating it. Should I downgrade. If so, how? If I can&#39;t downgrade, what should I do?

An error has occured. Please see log file - eclipse juno

Eclipse will not start and I haven&#39;t changed anything

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&#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 noticed that the new APK file is called **myapp-1.apk**, while it was usually called **myapp.apk**.
Can someone tell me how to fix?

ClassNotFoundException after ADT update

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;

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?

(Running Indigo with the ADT plugin, btw, not the bundled version, which failed to work in a different way. Java 1.6.0 45. Windows 8, unfortunately. Plenty of RAM etc)

Cannot create or edit Android Virtual Devices (AVD) from Eclipse, ADT 22.6

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?

Environment: linux x64.

I&#39;m trying to get set up with an Android development environment using IntelliJ in Ubuntu 12.04. I create an Android Application Module, but when I try to build, I get the following error:

&gt; android-apt-compiler: Cannot run program &quot;/home/jon/Programs/android-sdk-linux/platform-tools/aapt&quot;: java.io.IOException: error=2, No such file or directory

Several hours of scouring the internet hasn&#39;t helped.

By the way, I ran `locate aapt` in the terminal and found that `aapt` is located at `/home/jon/Programs/android-sdk-linux/build-tools/17.0.0/aapt`


Android Hello-World compile error: Intellij cannot find aapt

While I am trying to Install API 18 it shows only `&quot;Google API  18&quot;`(nothing more). Now if I try to install these google APIs from `Android SDK Manager` it shows a message `&quot;this package depends on &quot;Missing SDK  platform Android, API 18&quot;`. and Install button is disabled.

Does anybody here have Any idea how to install API 18(4.3_MR2 sdk) with eclipse

Missing SDK platform Android, API 18

I know this is a very rudimentary question, but to my surprise, I could not find any document about Android SDK Build-tools.
Besides Android SDK Tools and Android SDK Platform-tools, there are a bunch of Android SDK Build-tools as shown in the appended screenshot. Could anyone point to a source explaining all of them and help clarifying how a certain version of Android SDK Build-tools is picked for use?
 

![enter image description here][1]


**Edited (2014-02-27)**:

I still do not fully understand all the tools.  The following is my limited understanding based on Google&#39;s latest documents:

 - **Android SDK Build-tools** used to be components of **Android SDK Platform-tools**. They have been decoupled from Android SDK Platform-tools, so that the build tools can be updated independently of the integrated development environment (IDE) components.
 - **Android SDK Platform-tools** are customized to support the features of the latest Android platform.  They are backward compatible so that you always use the latest update of **Android SDK Platform-tools** even your app targets older Android platforms.
 - **SDK tools** are platform independent and are required no matter which Android platform you are developing on. 

I still do not understand the rationale of taking **Android SDK Build-tools** out of **Android SDK Platform-tools** which has a single instance and is easy to manage the update. The only possible reason that I can think of is that some apps have to rely on older build components to build them.  Google&#39;s document mentions this, but does not explain why. Looking at the release notes, you will notice that updates of **Android SDK Build-tools** are primarily for fixing bugs or/add support for new platforms. The only reason that I can think of for some apps to use older versions of **Android SDK Build-tools** is that they rely on certain bugs of **Android SDK Build-tools**. These apps would not function normally without being built with these bugs.  I wish Google could explain this better by giving one or two examples showing why these bugs in the tools are critical for certain apps.

What are the Android SDK build-tools, platform-tools and tools? And which version should be used?

Could anybody post a working solution for setting `ANDROID_HOME` via the terminal?

My path to the Android-SDK is `/Applications/ADT/sdk`.
