Question

the document
http://developer.android.com/guide/topics/data/data-storage.html

shows that there are multiple ways to save data, I need to do this in a widget and everytime I try to save i get errors…

for instance

      SharedPreferences settings = getSharedPreferences("NAME", 0);
      SharedPreferences.Editor editor = settings.edit();
      editor.putBoolean("silentMode", false);

      // Commit the edits!
      editor.commit();

Error

Description Resource    Path    Location    Type
The method getSharedPreferences(String, int) is undefined for the type AWidget

another attempt:

     String FILENAME = "hello_file";
     String string = "hello world!";

     FileOutputStream fos = openFileOutput("Test.txt", Context.MODE_PRIVATE);
     fos.write(string.getBytes());
     fos.close();

with error

Description Resource    Path    Location    Type
The method openFileOutput(String, int) is undefined for the type AWidget

whats the deal? I see no mention this does not work in a widget so why is it that these examples don’t work for me?

What is the preferred way to save this data?

Answer 1

So the issue is is that I cannot just use this function without substance the above code will work fine if I do it with context. in front of it…

 SharedPreferences settings = context.getSharedPreferences("NAME", 0);
      SharedPreferences.Editor editor = settings.edit();
      editor.putBoolean("silentMode", false);

      // Commit the edits!
      editor.commit();

So as you can see that is all that was need to get the shared preferences… and with this…

int[] allids = AppWidgetManager
.getInstance(context)
.getAppWidgetIds(new ComponentName(context, AwarenessWidget.class));

I can get all the IDs of my app and call onupdate and update each ones views based upon the saved preferences

I can elaborate more if anyone needs…

Baffels me no one was able to figure that one out and help me! seems very straight forward now!
