Hi,
Is it possible to share data between the Android framework and an app?
I'm modifying the Android framework login component so that a variable will
be saved upon login, and then later retrieved by another app. I'm trying to
use SharedPreferences, and my code looks like this:
In com.android.internal.policy.impl.PasswordUnlockScreen.java, I have the
following code to write to the SharedPreferences.
SharedPreferences prefs = getContext().getSharedPreferences("mypref",
Context.MODE_WORLD_READABLE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("mypref", "my data"
editor.commit();
In my other app, I have the following code to read from it.
Context con;
String data;
try {
con = this.createPackageContext("com.android.internal.policy.impl", 0);
SharedPreferences pref = con.getSharedPreferences("mypref",
Context.MODE_PRIVATE);
data = pref.getString("mypref", "0")
} catch (NameNotFoundException e) {
data = "0";
Log.e("No data shared", e.toString());
}
When I run the code, I keep getting the NameNotFoundException, as it claims
the application package com.android.internal.policy.impl is not found, so
my data is always "0".
How can I share data between these 2 components?
Thanks.
