我尝试从Google获取GCM registrationId。
我的代码：
String SENDER_ID = "722******53";
/**
* Registers the application with GCM servers asynchronously.
* <p>
* Stores the registration ID and the app versionCode in the application's
* shared preferences.
*/
private void registerInBackground() {
new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(context);
}
regid = gcm.register(SENDER_ID);
msg = "Device registered, registration ID=" + regid;
// You should send the registration ID to your server over
// HTTP, so it
// can use GCM/HTTP or CCS to send messages to your app.
sendRegistrationIdToBackend();
// 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) {
msg = "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 msg;
}
@Override
protected void onPostExecute(String msg) {
mDisplay.append(msg + "\n");
}
}.execute(null, null, null);
}
我收到错误：

答案 0 :(得分：8)
更改
<uses-permission android:name="com.example.manyexampleapp.c2dm.permission.RECEIVE" />
到
<!-- This app has permission to register and receive data message. -->
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
您收到异常是因为您尚未定义所需的权限
答案 1 :(得分：1)
如果在开发应用程序后安装了播放服务，
可能会发生com.google.android.c2dm.permission.RECEIVE权限已经给出但是android仍然抱怨同样的错误。
在这种情况下，您必须完全重新安装已开发的应用，才能使此权限有效。
