Modify your app/build.gradle to use Java 8 and avoid #22397.

    ...
    lintOptions {
        ...
        // To avoid error.
        checkReleaseBuilds false
    }

    // Plugin requires Java 8.
    compileOptions {
        targetCompatibility 1.8
        sourceCompatibility 1.8
    }
}

The plugin will automatically download pre-build native libraries from here if they haven't been downloaded.
