I save the value in one activity like this:

sPref = getPreferences(MODE_PRIVATE); SharedPreferences.Editor edit = sPref.edit(); edit.putBoolean(ON_CAMERA, true); edit.commit();

And I get in another way:

 sPref = getPreferences(MODE_PRIVATE); Boolean bl = sPref.getBoolean(ON_CAMERA, false);

The problem is that bl always false . After reading the literature, I noticed that SharedPreferences works with only one activity. Tell me how to save and get the value correctly?

PS I save the setting value, which is true or false (the default) in one activation, and in the other I should get this value, depending on which change the behavior of the button.

To obtain an instance of the SharedPreferences class, three methods are used to access the settings in the application code:

getPreferences() - inside the activity to access the activity-specific preference;
getSharedPreferences() - inside the activity to access application-level preferences;
getDefaultSharedPreferences() - from the PreferencesManager object to get the public setting provided by Android.

To access the settings from anywhere in the application, you need to use the second or third method:

 SharedPreferences sharedPreferences = getSharedPreferences(APP_PREFERENCES, Context.MODE_PRIVATE);
