Getting this complaint from IntelliJ 13: 

    8:15:48 PM Gradle &#39;&lt;project&gt;&#39; project refresh failed:
               SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

               : Gradle settings

I have tried to spam my local.properties in every directory I can think of but still getting this error.  What gives?

Where does local.properties go for android project?

Is it possible to change the package name of an Android application using Gradle? 

I need to compile two copies of the same app, having a unique package name (so I can publish to the market twice).

How to change the Android app package name when assembling with Gradle?

I am using following line in android ant build (project.properties):

    dex.force.jumbo=true

Now we are migrating from ant to Gradle. Is it possible to get jumbo mode active in Android Gradle build?

Android Build: Dex Jumbo Mode in Gradle

I use the [new *command line tools* for Android][1] because the old *sdk-tools* repository of Android isn&#39;t available anymore. So I changed my gitlab-ci to load the `commandlintools`. But when I try to run it I get the following error:

    Warning: Could not create settings
    java.lang.IllegalArgumentException

I am converting one of my apps to Gradle and would like to use the new build flavor features to have a paid and a free ad based flavor. 

I want only the ad based version to depend on the admob SDK. 

My build file looks like this: 

    buildscript {

            mavenCentral()
        }

    }

        defaultConfig {
            minSdkVersion 10
            targetSdkVersion 18
        }

    		Free { 
    			dependencies {

    	        }

       	compile fileTree(dir: &#39;libs&#39;, include: &#39;*.jar&#39;)
    }

Is there a way to configure the dependency in the free product flavor to have its own libs folder that is merged with the main libs folder that contains general libraries for both flavors? 

If this is possible how would I define this folder?

Android Studio: Plugin with id &#39;android-library&#39; not found

**edit: (aug-2016)**

That question is from November 2013 (while Android Studio was still in Developer Preview mode), 

Currently (AS v2.2, Aug-2016) during instalation AS asks to choose the SDK folder (or install on their default) and it automatically applies to which ever project you&#39;re opening.

That means any possible workaround or fix is irrelevant as the issue is not reproducible anymore.


**original question:**

we have this project with several modules that is already configured and executes correctly on another developer PC using a wrapper. I cloned the complete git submodules into my machine.

Below it&#39;s a directly print of my command line:

    $ ./gradlew
    
    FAILURE: Build failed with an exception.
    
    * Where:
    Build file &#39;/home/budius/project_name/ActionBar-PullToRefresh/library/build.gradle&#39; line: 1
    
    * What went wrong:
    A problem occurred evaluating project &#39;:ActionBar-PullToRefresh:library&#39;.
    &gt; SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
    
    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
    
    BUILD FAILED
    
    Total time: 6.378 secs

    $ echo $ANDROID_HOME
    /home/budius/Applications/android-studio/sdk
    $ 

so, as you can see the ANDROID_HOME is there. What else do they want? What&#39;s wrong here.

running on Ubuntu 13.04

**edit:**

I already created a local.properties file with `sdk.dir=&lt;path&gt;` on the project root and it works. But that makes the code harder to port across systems n build server, so the question is still open. 

Anyone knows why the ANDROID_HOME is not working and what to do to make it work?

I want to use master version of my lib from mavencentral.

Is it possible to declare git repository as dependency in android gradle?

Is it possible to declare git repository as dependency in android gradle?

I have looked at the [documentation][1] for building with Gradle, but I&#39;m still not sure what the difference between `compileSdkVersion` and `targetSdkVersion` is.

All it says is:
&gt; The `compileSdkVersion` property specifies the compilation target.

Well, what is the &quot;compilation target&quot;?

I see two possible ways to interpret this:

1. `compileSdkVersion` is the version of the compiler used in building the app, while `targetSdkVersion` is the [&quot;API level that the application targets&quot;][2]. (If this were the case, I&#39;d assume `compileSdkVersion` must be greater than or equal to the `targetSdkVersion`?
2. They mean the same thing. &quot;compilation target&quot; == &quot;the API level that the application targets&quot;
3. Something else?

I see that [this question][3] has been asked before, but the one answer just quotes the doc, which is what is unclear to me.

When trying to build OpenStreetMapView from git://github.com/osmdroid/osmdroid, I get this error:

    failed to find target with hash string android-23: D:\Users\myusername\AppData\Local\Android

How can I fix this? Previous questions similar to this suggest checking that android 23 is not installed, but in my case, it is.

Below is some pertinent info:

ANDROID_HOME is `D:\Users\myusername\AppData\Local\Android\sdk`

`D:\Users\myusername\AppData\Local\Android\sdk\platforms\` contains the directory \android-23\, (as well as android-19, android-21, android-22, android-MNC)

Build errors after Android Studio 3.2.1 upgrade

I am trying to convert our Android application to a gradle build.  I have the project and it&#39;s libraries building successfully.   I am now trying to create separate apks for our various environments (dev/test/prod have different urls for the restful services they consume).

	    def manifestText = manifestFile.getText()
	    def matcher = pattern.matcher(manifestText)
	    matcher.find()
	    def versionCode = Integer.parseInt(matcher.group(1))
	    def manifestContent = matcher.replaceAll(&quot;versionCode=\&quot;&quot; + ++versionCode + &quot;\&quot;&quot;)
	    manifestFile.write(manifestContent)
	}
	
	tasks.whenTaskAdded { task -&gt;
	    if (task.name == &#39;generateReleaseBuildConfig&#39;) {
	        task.dependsOn &#39;increaseVersionCode&#39;

	}

The problem is that my BuildConfig.java doesn&#39;t seem to get the static variables injected, therefore I get errors similar to:

	/Users/path/to/project/MainActivity.java:348: error: cannot find symbol
				startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(BuildConfig.URL_SEARCH)));
				                                                                  ^

My build/source/buildConfig/debug/com/.../BuildConfig.java file contains:

	/**
	 * Automatically generated file. DO NOT MODIFY
	 */
	package com....;
	
	public final class BuildConfig {

What am I doing wrong?

BuildConfig not getting created correctly (Gradle Android)

Building my Android app takes about 90 seconds (*&quot;fast&quot;*), up to 3 minutes for each update to my code. It&#39;s a complete waste of time as it really and I assume a solution must be within reach. I tried investigating the issue and found different blog-posts and SO answers with suggestions, most of which I&#39;ve tried.

 - I have the gradle.properties file with org.gradle.deamon=true
 - I run on Android Studio with Gradle Prefence to do offline work (improved, but still slow)
 - I run on command line (which is faster, but still slow)
 - In build.gradle, defaultConfig, I have multiDexEnabled set to false
 - In build.gradle, dexOptions, I have preDexLibraries set to false
 - In gradle-wrapper.properties I fetch a recent gradle version (2.8) (the significant speed changes happened on 2.4)

The process that seems to take long, about 85% of total build time is **:app:transformClassesWithDexForDebug**

What is that process actually doing? I can find people who have crashes on it, but it works fine for me, except for the fact that it takes a lot of time. And do I need it, since I don&#39;t really need Dex at this point?

Also, I have 13 dependencies and 3 testCompile dependencies. I already point to specific play packages, so I&#39;m not compiling stuff I don&#39;t need. If I understand things correctly, gradle is building all those libraries each project build as well. If that is correct, is there a way to skip that? Can I build them myself as wrapped-up libraries and include them without the need for them to be processed each time? That might make me lose some flexibility for future changes to dependencies, but at this point I feel like I&#39;m losing over an hour a day easily on waiting for gradle. I&#39;m not sure if flexibility is worth that much to me.

I&#39;m looking forward to get any pointers on how I can improve my build process. Thank you in advance.

Gradle build slow on transformClassesWithDexForDebug

I believe I&#39;ve followed the instructions in the Android SDK, and I&#39;m now trying to build the sample LunarLander (random one picked)

    $ cd samples/android-11/LunarLander
    $ ant debug
    Buildfile: build.xml does not exist!
    Build failed

I believe all PATHs are setup correctly. 
I&#39;ve done this before in an older Android SDK release and I know I didn&#39;t encounter this error, so I&#39;m pretty confused as to what&#39;s wrong.  

Oh, one more piece of info -- I have only installed the 3.0 platform package, so I&#39;m not sure if that is an error or not.


How to build the Android sample projects using Ant? build.xml does not exist

I have a command line apk generator which compiles a lot of APKs using the same source code, so these apps have the same dependencies.

In the gradle documentation I can see this:
&gt; The Gradle project needs network connectivity to download dependencies.

I know that it is possible to configure gradle to work offline and not download the same dependencies that it has downloaded for other apks. How can this offline mode be activated?

How to configure gradle to work &quot;offline&quot; (using cached dependencies)

I want to setup the Android dev environment from command line, and encounter the following issue:

    wget http://dl.google.com/android/android-sdk_r22.0.5-linux.tgz

after extract the file, run

    tools/android update sdk --no-ui

However, it is too slow on running

    Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml

The result is that nothing in folder build-tools, and I want is aapt and apkbuilder, since I want to build apk from command line without ant.
