Android getDefaultSharedPreferences
android, sharedpreferences
Solution
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:
- MODE_WORLD_READABLE
- MODE_WORLD_WRITEABLE
- MODE_MULTI_PROCESS
Problem
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.
