Android Studio: New Gradle Build Ndk Sample App Error

I build sample project MoreTeapots from https://github.com/googlesamples/android-ndk and get errors Information:Gradle tasks [:app:assembleAllDebug] :app:copyArm64-v8aDebugAllM

Solution 1:

Try this

tasks.withType(JavaCompile) {
    sourceCompatibility = JavaVersion.VERSION_1_7
    targetCompatibility = JavaVersion.VERSION_1_7
}

Bug is submitted here https://code.google.com/p/android/issues/detail?id=179660

edit: append it to end of app build.gradle file outside all of sections

Solution 2:

Alternatively, the two lines can be added immediately following the 'apply plugin: ...'

apply plugin: 'com.android.model.application'
sourceCompatibility = JavaVersion.VERSION_1_7targetCompatibility= JavaVersion.VERSION_1_7
