I'm trying to figure out the whole Android licensing thing, and getting frustrated. In the emulator, I run the app with no account, or one that isn't in the testing environment, and it seems to work correctly, returning the not licensed response and pops up the buy the app now message.
When I try to run it on an actual Android device, it returns licensed every time, even though the device account isn't one that is in the testing environment. Also, even though it returns licensed, the "checking license" box never goes away, unless you click cancel. Then it just lets you use the app as if it was licensed. It's mostly C&P from the example, with a few changes. I removed the check license button and the status text box.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mHandler = new Handler();
// Try to use more data here. ANDROID_ID is a single point of attack.
String deviceId = Secure.getString(getContentResolver(), Secure.ANDROID_ID);
// Library calls this when it's done.
mLicenseCheckerCallback = new MyLicenseCheckerCallback();
// Construct the LicenseChecker with a policy.
mChecker = new LicenseChecker(
this, new ServerManagedPolicy(this,
new AESObfuscator(SALT, getPackageName(), deviceId)),
BASE64_PUBLIC_KEY);
doCheck();
ArrayAdapter<String> booksAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mBooks);
this.setListAdapter(booksAdapter);
}

I just don't know what I need to change to make it work... or if the license is somehow cached (even though this is the first time I've run it on this device) and if I can uncache it without wiping the device, as that'll be nice for when I do testing on other apps. Also, how do I remove the "checking license" message without having to click the cancel button... should I just make it so that it doesn't show up?
