My code is:
final String eulaKey = "mykey";
final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
boolean hasBeenShown = prefs.getBoolean(eulaKey, false);
Always returns different values depending on os version. Tested in 2.2, 2.3.4, 3.2, 4.0.3 - returns correct value. But for device Zte blade with 2.3.7 with CianogenMod 7.1 - result is always false. I suppose default value for getBoolean.
Here is code writing boolean:
final String eulaKey = "mykey";
final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean(eulaKey, true);
editor.commit();
Does anybody have any idea?
Update: Comparing my current code with my previous version of code - there is no difference in code. Only difference is in manifest: code works Ok with minVersion=8 and targetVersion=8 Now I'm compiling with minversion=8 and target=13 /because of Admob/. Maybe some APIs changed, but I found nothing on this.
SOLUTION: -Starting app from shortcut and from menu gives me different DefaultSharedPreferences. After removing DefaultSharedPreferences from my code - it works perfect. I can't just say: people don't make shortcuts, so I had to change code.
Try it this way:
final String eulaKey = "mykey";
Context mContext = getApplicationContext();
mPrefs = mContext.getSharedPreferences("myAppPrefs", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = mPrefs.edit();
editor.putBoolean(eulaKey, true);
editor.commit();
in which case you can specify your own preferences file name (myAppPrefs) and can control access persmission to it. Other operating modes include:
