Android support multidex library implementation

I have hit the magic dex limit because my application uses a lot of jars (drive api, greendao, text to pdf, support.. ).

My current solution was that I literally created a second apk just for google drive wich I called from the main apk. But now I found out that android finally supports this with this library. My problem is just that I don't know how to implement it(preferably without gradle). I can't find any good tutorials for it.

Okey I am losing my mind trying to implement this.. I have found this:
http://blog.osom.info/2014/10/multi-dex-to-rescue-from-infamous-65536.html

And I added:

android:name="android.support.multidex.MultiDexApplication"


To my manifest file and

protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}


To my mainactivity.java

Also installed gradle plugin for eclipse, exported gradle to get build.gradle file wich I changed to:

apply plugin: 'android'

dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':android-support-v7-appcompat')
compile project(':Sync')
compile project(':gdrive:google-play-services_lib')
}


android {
compileSdkVersion 14
buildToolsVersion "21.1.1"


sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src-gen','src']
resources.srcDirs = ['src-gen','src']
aidl.srcDirs = ['src-gen','src']
renderscript.srcDirs = ['src-gen','src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}

// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')

// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}

dexOptions {
preDexLibraries = false
}
}

afterEvaluate {
tasks.matching {
it.name.startsWith('dex')
}.each { dx ->
if (dx.additionalParameters == null) {
dx.additionalParameters = ['--multi-dex']
} else {
dx.additionalParameters += '--multi-dex'
}
}
}


But The error is still the same :(

Answer

The Blog was the old solution.

With Android Studio 0.9.2 & Gradle Plugin 0.14.1, you only need to:

  1. android:name="android.support.multidex.MultiDexApplication" or add MultiDex.install(this) in your custom Application's attachBaseContext method or your custom Application extend MultiDexApplication

  2. add multiDexEnabled = true in your build.gradle android { defaultConfig { ... multiDexEnabled = true } }

Done.

Sorry for my poor English
