You can store key/value pairs in Accounts, via the Account
Manager. I never did it, but I guess it could fit your needs,
since you anyway seem to plug-in into some Account
validation, right?

See getUserData(), setUserData()

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.
