RxAndroid aborts or does not build when Play Services is added

Question

I'm having some issues getting RxAndroid and Google Play Services running together or even build the project in Android Studio after adding Google Play Services. I've used the following 2 helpful sites as references: How to setup retrolambda and Functional Reactive Programming with RxJava in Android. Now maybe I missed something, but I've had issues with java.exe (java 8) either aborting during the build with an exit error or issues with java 8 when running the actual application. From the errors I deduced that I needed retrolambda and there were still issues building my project.

Answer 1

After some trial and error, research, etc. Here's what I found that worked for me. Please note that some of the commented out values at the end of a line were values that I had tried previously.

Project build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
//        jcenter()
    mavenCentral()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'   //1.3.0
    classpath 'me.tatarka:gradle-retrolambda:3.2.0'   //2.5.0
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {
//        jcenter()
    mavenCentral()
}
}

Module build.gradle

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
compileSdkVersion 22   //21
buildToolsVersion "21.1.2"    //21.1.2

defaultConfig {
    applicationId "com.your.app"
    minSdkVersion 18
    targetSdkVersion 22  //21
    multiDexEnabled = true

}
buildTypes {
    release {
    minifyEnabled false
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}


dexOptions {
    javaMaxHeapSize "2g"
    preDexLibraries = true  //false
    incremental false
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'  //21.0.3   22.2.1
compile 'com.google.android.gms:play-services:7.8.0' //7.8.0
compile 'io.reactivex:rxandroid:0.24.0'
}

retrolambda {
jvmArgs '-noverify'
jdk System.getenv("JAVA8_HOME")
oldJdk System.getenv("JAVA7_HOME")
javaVersion JavaVersion.VERSION_1_7
defaultMethods false
incremental true

}

proguard-rules.pro

-dontwarn java.lang.invoke.*

In addition, I added the above referenced path environment values JAVA7_HOME, JAVA8_HOME which point to the appropriate directory for each java install.
