谷歌云信息登记失败 [英] Google Cloud Messaging register fails
问题描述
问题解决了 更新：
我解决了这个问题。 问题出在方法registerGCMInBackground（）。 GoogleCloudMessaging.getInstance（）预计的ApplicationContext。
I solved this Problem. The problem is in method registerGCMInBackground(). GoogleCloudMessaging.getInstance() expects the ApplicationContext.
private void registerGCMInBackground(final String userId) {
new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... params) {
String msg = "";
Log.d("Register GCM", "started");
try {
if (gcm == null) {
//PROBLEM SOLVED HERE
gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
Log.d("GCM", gcm.toString());
}
regid = gcm.register(SENDER_ID); //////NULL POINTER EXCEPTION
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over HTTP
sendRegistrationIdToBackend(userId, regid);
// For this demo: we don't need to send it because the device will send
// upstream messages to a server that echo back the message using the
// 'from' address in the message.
// Persist the regID - no need to register again.
storeRegistrationId(context, regid);
} catch (IOException ex) {
return "Error :" + ex.getMessage();
// If there is an error, don't just keep trying to register.
// Require the user to click a button again, or perform
// exponential back-off.
}
return regid;
}

-------- Solved Problem--------------
我有问题，我的注册Android设备的GCM（谷歌云消息传递）。我使用的是从谷歌开发者的例子。随着使用谷歌开发的例子我保证以下几点：
I have problems with registering my Android device at GCM (Google Cloud Messaging). I'm using the example from Google Developers. With the use of the Google Developer Example I ensured the following things:
- 在加入最新的播放服务资料库
- 在加入最新的播放服务JAR
- 在正确的清单文件
- 在安装装置，具有播放服务APK
- 使用项目编号为SENDER_ID
这似乎是这样的问题同样的问题。遗憾的是仍然没有回答。 我得到一个空指针异常的下面一行： REGID = gcm.register（SENDER_ID）;
It seems to be the same issue like this Question. Unfortunately still not answered. I'm getting a Null Pointer Exception by the following line: regid = gcm.register(SENDER_ID);
下面是我的问题code： 样品活动
Here is my Problem Code: Sample Activity

public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";
private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
String SENDER_ID = "xxxxxxxxxxxxxxx";
GoogleCloudMessaging gcm;
AtomicInteger msgId = new AtomicInteger();
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registration);
final Button register = (Button) findViewById(R.id.btn_register);
register.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
EditText mobilePhoneNumber = (EditText) findViewById(R.id.et_phonenumber);
if(!mobilePhoneNumber.getText().toString().isEmpty()){
User user = new User();
user.setMobilePhoneNumber(mobilePhoneNumber.getText().toString());
EditText firstName = (EditText) findViewById(R.id.et_firstName);
user.setFirstName(firstName.getText().toString());
EditText lastName = (EditText) findViewById(R.id.et_lastName);
user.setLastName(lastName.getText().toString());
