Error:Execution failed for task ':app:dexDebug'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin/java‘‘ finished with non-zero exit value 2
解决：
build.gradle中添加：

defaultConfig {
  multiDexEnabled true
}
compile ‘com.android.support:multidex:1.0.1‘

application中添加：

@Override
protected voidattachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
