sendUserActionEvent() is null
I also encuntered the same in S4. I've tested the app in Galaxy Grand , HTC , Sony Experia but got only in s4. You can ignore it as its not related to your app.
I solved this problem on my Galaxy S4 phone by replacing context.startActivity(addAccountIntent);with startActivity(new Intent(Settings.ACTION_ADD_ACCOUNT));
Same issue on a Galaxy Tab and on a Xperia S, after uninstall and install again it seems that disappear.
The code that suddenly appear to raise this problem is this:
public void unlockMainActivity() { SharedPreferences prefs = getSharedPreferences("CALCULATOR_PREFS", 0); boolean hasCode = prefs.getBoolean("HAS_CODE", false); Context context = this.getApplicationContext(); Intent intent = null; if (!hasCode) { intent = new Intent(context, WellcomeActivity.class); } else { intent = new Intent(context, CalculatingActivity.class); } intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); (context).startActivity(intent);}
