Retrieve the Auth Token in GDK

Question

Retrieve the Auth Token in GDK
After Inserting the Mirror Account Successfully Now getting the Auth Token in APK side (GDK side).

Mainfest.xml

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />

Activity Code :

 AccountManager accountManager = AccountManager.get(this);
    // Use your Glassware's account type.
    Account[] accounts = accountManager.getAccountsByType(ACCOUNT_TYPE);//Same Account_type  which was passed from Mirror API 
    if (accounts != null && accounts.length > 0) {
        Log.d("MainActivity ", "MainActivity Account");
        for (int i =0;i<accounts.length;i++)
{     
accountManager.getAuthToken(accounts[i], AUTH_TOKEN_TYPE, null, this, new AccountManagerCallback<Bundle>() {
            public void run(AccountManagerFuture<Bundle> future) {
                try {
                    Log.d("MainActivity ", "MainActivity AccountManagerFuture");
                    UserId = future.getResult().getString("USERID"); // Line Number 133
                    Log.d("EOS_USERID ","UserId :-"+ UserId);
                    String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
                    Log.d("token","token :-"+ token);
                    // Use the token.
                } catch (Exception e) {
                    // Handle exception.
                    e.printStackTrace();
                }
            }
        }, null);
        }
