This is guide http://tools.android.com/tech-docs/new-build-system/gradle-experimental. Its app build.gradle

How can I solve? Thanks.

UPDATE: Solved. I add

    compileOptions.with {
    sourceCompatibility = JavaVersion.VERSION_1_7
    targetCompatibility = JavaVersion.VERSION_1_7
}

to app build.gradle like

apply plugin: 'com.android.model.application'
model {
android {
    compileSdkVersion    = 22
    buildToolsVersion    ="22.0.1"

    defaultConfig.with {
        applicationId    = "com.sample.moreteapots"
        minSdkVersion.apiLevel    = 10
        targetSdkVersion.apiLevel = 22

    }
}
android.ndk {
    moduleName ="MoreTeapotsNativeActivity"
    cppFlags   += "-I${file("src/main/jni/cpufeatures")}".toString()
    cppFlags   += "-I${file("src/main/jni/native_app_glue")}".toString()
    cppFlags   += "-I${file("src/main/jni/ndk_helper")}".toString()

    // CFlags is configured in similiar way as cppFlags
    // CFlags    += "-I${file("src/main/jni/native_app_glue")}".toString()

    ldLibs     += ["android", "EGL", "GLESv2","log"]
    stl         = "stlport_static"
}

android.sources {
    main {
        jni {
            source {
                srcDirs 'src/main/jni'
            }
        }
    }
}

android.productFlavors {
    create ("arm7") {
        ndk.abiFilters += "armeabi-v7a"
    }
    create ("arm8") {
        ndk.abiFilters += "arm64-v8a"
    }
    create ("x86-32") {
        ndk.abiFilters += "x86"
    }
    // for detailed abiFilter descriptions, refer to "Supported ABIs" @
    // https://developer.android.com/ndk/guides/abis.html#sa
    // build one including all productFlavors
    create("all")
}
compileOptions.with {
    sourceCompatibility = JavaVersion.VERSION_1_7
    targetCompatibility = JavaVersion.VERSION_1_7
}

}

Answer 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

Answer 2

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

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