Contacting licensing server

I'm trying to publish my app for 3 hours now, but I can't get the license check to work.

In my onCreate method I got this code:

// Try to use more data here. ANDROID_ID is a single point of attack.
String deviceId = Secure.getString(getContentResolver(), Secure.ANDROID_ID);
String pckName = getPackageName();

// 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, pckName, deviceId)), BASE64_PUBLIC_KEY);

mChecker.checkAccess(mLicenseCheckerCallback);

And the callback looks like this

private class MyLicenseCheckerCallback implements LicenseCheckerCallback {
    public void allow(int policyReason) {
        if (isFinishing()) 
            return; // Don't update UI if Activity is finishing.
        // Should allow user access.
        Main.isLicensed = true;
    }

    public void dontAllow(int policyReason) {
        if (isFinishing())
            return; // Don't update UI if Activity is finishing.
        Main.isLicensed = false;
    }

    public void applicationError(int errorCode) {
        if (isFinishing())
            return; // Don't update UI if Activity is finishing.
        Main.isLicensed = false;
    }
}

Only the dontAllow method gets called. And the response code is 291.

In logcat I get "Error contacting licensing server."

• The app is uplodaded to the developer console.

• The public key is correct copied (without any spaces).

• The phone (Samsung Galaxy S2 with Android 4.0.4 Stock) got internet

Any ideas?

Code looks good to me. But I have a similar problem at the moment. Did you ...

• restarted network connection
• restarted your phone
• clear the data of google play store (settings -> apps -> google play store)
• clear the data of google play services
• logged in your device google play store with your publisher/testing account

Let me know, if solved the problem.

Thanks Best wishes
