Answer 1

I saw that the method getNoBackupFilesDir is found in android.support.v4.content.ContextCompat.

Seems that the problem was that I had an old appcompat-v7 included in the project. Download with the SDK manager the last version of Android Support Library and then follow the steps for Adding libraries with resources and add the library to your application project.

I got this error:

java.lang.NoSuchMethodError: No static method getNoBackupFilesDir(Landroid/content/Context;)Ljava/io/File; in class Lcom/google/android/gms/common/util/zzx; or its super classes (declaration of 'com.google.android.gms.common.util.zzx' appears in /data/data/com.crave.iapdemo/files/instant-run/dex/slice-com.google.android.gms-play-services-basement-10.0.1_b9da1447b99cc6cbc2fa601fb84d0418780bfa55-classes.dex)

in this line:

InstanceID.getInstance(this);

The solution for me was upgrading this:

dependencies {
    // play services
    compile 'com.google.android.gms:play-services-gcm:9.0.0'
    compile 'com.google.android.gms:play-services-analytics:9.0.0'
}

into:

dependencies {
    // play services
    compile 'com.google.android.gms:play-services-gcm:10.0.1'
    compile 'com.google.android.gms:play-services-analytics:10.0.1'
}
