How to use buildship for android?

I have a dummy project, which I succeed to compile through buildship plugin in eclipse IDE.
This is my local.properties file:
sdk.dir=C:/Asta/altro/adt-bundle/sdk
This is settings.gradle file
rootProject.name = 'testgradle'
This is my build.gradle file
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
}
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.example.testgradle"
minSdkVersion 14
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
}
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
lintOptions {
abortOnError false
}
}
sourceCompatibility = 1.6
targetCompatibility = 1.6
repositories {
jcenter()
flatDir {
dirs 'libs'
}
}
dependencies {
compile 'org.slf4j:slf4j-api:1.7.21'
compile 'com.android.support:appcompat-v7:23.4.0'
testCompile 'junit:junit:4.12'
}
task wrapper(type: Wrapper) {
gradleVersion = '2.10'
}
Despite I got the apk fully compiled, eclipse is not integrated: still seeing missing libraries and giving more than a 100 errors! All the libs are perfectly managed by gradle in \build\intermediates\ and assembled into apk, but the eclipse IDE is not "live". I would like to use gradle to download and explode the libraries and then to inform eclipse and let it to make the apk with its own builder.

Buildship can be used only to run Android tasks (assembleDebug).
During the build process it will load dependencies and tell if there're some errors.
To load dependencies into Java classpath, to see errors in Eclipse and resolve imports you can either manually add .jar files to your Java Build Path or use this Gradle plugin: https://github.com/greensopinion/gradle-android-eclipse.
It generates classpath for Eclipse project and you just import it into the IDE.
To run Gradle tasks you can create a Run configuration (named "Gradle Project") and put there your task and Working directory.

Built apk contains unneeded resources

Having an issue where the apk being generated by our Gradle build contains a bunch of unnecessary files inside a test/resources directory
Our application build gradle contains several local module dependencies which are built as android libraries.
I know there is packagingOptions field in Gradle but you can't exclude directories as far as I can tell. Excluding each file isn't an option. Anyway, I would like to know the root cause for this.
Application gradle build:
apply from: "${rootDir}/android_application.gradle"
dependencies {
compile project(':local-lib1')
//... etc
compile project(':local-libN')
testCompile libraries['junit']
}
android {
defaultConfig {
versionCode 1
versionName "1.0"
multiDexEnabled true
}
}
And android_application.gradle:
apply plugin: 'com.android.application'
android {
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
compileSdkVersion android_sdk_version
buildToolsVersion android_build_tools_version
defaultConfig {
minSdkVersion android_min_sdk_version
targetSdkVersion android_target_sdk_version
}
buildTypes {
}
}
All modules are structured like so:
module
|
--AndroidManifest.xml
--build.gradle
--assets/
--res/
--src
|
-- main/
| |
| --java/
| --resources/
|
-- test/
|
--java/
--resources/
Why are test/resources being included in apk? How can I exclude them?
Edit (to show lib gradle):
Example lib gradle:
apply from: "${rootDir}/android_library.gradle"
dependencies {
compile 'com.android.support:multidex:1.0.0'
// ...etc external deps
// test deps
testCompile libraries['logback-classic']
testCompile libraries['junit']
testCompile libraries['mockito-core']
// etc...
}
android {
packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
exclude 'META-INF/ASL2.0'
exclude 'META-INF/notice.txt'
exclude 'META-INF/license.txt'
}
}
android_library gradle:
apply plugin: 'android-library'
android {
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
compileSdkVersion android_sdk_version
buildToolsVersion android_build_tools_version
defaultConfig {
minSdkVersion android_min_sdk_version
targetSdkVersion android_target_sdk_version
}
buildTypes {
release {
}
}
}
I am building with gradlew.bat -x test build
The test/resources included in the apk contains all the files in the corresponding test/resources for each lib. The size of directory (uncompressed) is 10mb so adds unreasonable amount to size of overall apk.

Try the resource shrinking. As per Google Documentation: "The Gradle build system for Android supports
resource shrinking": the automatic removal of resources that are
unused, at build time, in the packaged app. In addition to removing
resources in your project that are not actually needed at runtime,
this also removes resources from libraries you are depending on if they are not actually needed by your application
android {
...
buildTypes {
test {
minifyEnabled true
shrinkResources true
...
}
}
}

Think I've solved the issue.
I had in app build.gradle and each library build.gradle:
android {
sourceSets {
main {
resources.srcDirs = ['src']
}
}
}
Changed to
android {
sourceSets {
main {
resources.srcDirs = ['src/main']
}
}
}
I guess gradle was taking every resources dir under src/ and merging them into one - http://tools.android.com/tech-docs/new-build-system/resource-merging

Android Studio 1.0 failing build at dexDebug or dexRelease

I recently upgraded from Android Studio 0.9.2 to 1.0 (including version 1.0.0 of the Gradle plugin) and I'm having an issue with building my project.
Whenever I build I get the following exception at the dexDebug or dexRelease step:

I tried increasing the heap size of Android Studio to -Xmx4096m but to no avail.
In Android Studio 0.9.2 with version 0.14 of the gradle plugin building worked fine.
This is the build.gradle file of my project:

buildscript {

What could be the cause of this issue and how can it be solved?

Looks like Android Studio ran out of memory, try increasing the memory size in AndroidStudio.app/Contents/bin/studio.vmoptions
-Xms256m
-Xmx1024m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops
as per suggested from answers in Android Studio - How to increase Allocated Heap Size
Additionally you may want to add
dexOptions {
javaMaxHeapSize "4g"
}
to your module build.gradle as per Android Studio Google JAR file causing GC overhead limit exceeded error

Looks like dexing runs out of memory. Try:
android {
dexOptions {
javaMaxHeapSize "2048M"
}
}
For additional options, see dex options in the Gradle Plugin User Guide.

AndroidAnnotations with IntelliJ IDEA and 'android-apt' Gradle plugin : "Could not find property 'androidTestCompile' on configuration container"

I am trying to make a Hello World with AndroidAnnotations and Gradle in IntelliJ IDEA.
(I only have some experience with IntelliJ, all the other stuff is completely new to me.)
I have created a new Gradle: Android Module in IntelliJ IDEA and then edited build.gradle per "Configure your gradle" in the AndroidAnnotations' official guide.
Unfortunatelly, I get this error saying I have no idea what (on line 18: apply plugin: 'android-apt')
Gradle: A problem occurred evaluating project ':Hello'.
> Could not find property 'androidTestCompile' on configuration container.

Version Compatibility.
androidTestCompile was introduced in version 0.9.0 of the Android Gradle plugin (and I was using 0.7.+ here), so 0.9.0 is the minimum one should use with android-apt's newer versions (3.0.1 here).
Also, you might have some more problems with incompatible versions of all these tools.
Here is a table of version compatibility among Android Studio, Android Gradle plugin and Gradle

play_licensing throws AIDL error with downloader_library for APK Expansion with Gradle

I tried to use the APK Expansion libs zip_file and downloader_library (which requires play_licensing). zip_file worked fine since it has no dependencies, but play_licensing throws an error when I try a Gradle sync.
Android Studio spits out this error log:

I haven't modified any of the libraries, but since they weren't built for Gradle, I copied over a build.gradle from another project and modified them accordingly.

I'm currently using Android Studio 0.5.1 and gradle 0.9.0 with build tools 19.0.3

I had the same problem and found solution for it. Just create a new package with the name com.android.vending.licensing under the aidl folder and move your aidl files there:
P.S. you also have to add empty <application /> tags to AndroidManifest.xml of play_licensing and downloader_library modules. And compile project(':PlayLicensing') to the dependencies tag of the build.gradle of the downloader_library
