title: Getting error: Could not find class 'android.app.AppOpsManager', referenced from method com.google.android.gms.common.GooglePlayServicesUtil.zza
body: <p>I receive this error and program crashes when I try to run the app on phone with older than API level 22. However the app works fine on phone with API level 22. What could be the reason for that.</p>
