我希望启用自动登录到我的应用程序，但出现的问题是在调用自动登录功能后服务正在启动和绑定：

答案 0 :(得分：0)
我在ServiceConnection块中发布了自动登录代码。问题是服务只在onCreate块之后连接，因此在对它调用任何东西时它总是为NULL。
private ServiceConnection mConnection = new ServiceConnection() {

imService = ((MessagingService.IMBinder) service).getService();

final String userName = SaveSharedPreference.getUserName(getApplicationContext());
final String password = SaveSharedPreference.getPassword(getApplicationContext());
Log.v("TEST GCM Service Login", "SharedPref Username is " + userName + " and password " + password);
//Log.v("TEST GCM Service Login", "The value of imService is: " + imService.toString());
if (imService == null) {
Log.v("TEST GCM Service Login", "Service is NULL");
Toast.makeText(getApplicationContext(),
R.string.not_connected_to_service,
