Question

I have a settings application from which i have to retrieve other applications preferences, but i don't have the details of keys in them, how can i retrieve all the available keys and values in that preference?

Thanks, Swathi

Answer 1

Okay! using this code in Application 1 ( with package name is "com.sharedpref1" ) to store data with Shared Preferences.

SharedPreferences prefs = getSharedPreferences("demopref",
                    Context.MODE_WORLD_READABLE);
            SharedPreferences.Editor editor = prefs.edit();
            editor.putString("demostring", strShareValue);
            editor.commit();

And using this code in Application 2 to get data from Shared Preferences in Application 1. We can get it because we use MODE_WORLD_READABLE in application 1:

    try {
                con = createPackageContext("com.sharedpref1", 0);
                SharedPreferences pref = con.getSharedPreferences(
                        "demopref", Context.MODE_PRIVATE);
                String data = pref.getString("demostring", "No Value");
                displaySharedValue.setText(data);

            } catch (NameNotFoundException e) {
                Log.e("Not data shared", e.toString());
            }
