我的大多数Android设备都遇到了问题。我可以使用我的Nexus One接收注册ID,但是对于大多数其他Android设备,它会返回一个空字符串。
当我调用
时,它返回空字符串regid = gcm.register(SENDER_ID);
MainActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SENDER_ID = getString(R.string.sender_id);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
gcm = GoogleCloudMessaging.getInstance(this);
regid = getRegistrationId(getApplicationContext());
if (regid.isEmpty()) {
registerInBackground();
}
setContentView(R.layout.activity_getnumber);
}
private String getRegistrationId(Context context) {
final SharedPreferences prefs = getGCMPreferences(context);
String registrationId = prefs.getString(PROPERTY_REG_ID, "");
if (registrationId.isEmpty()) {
Log.i("tag", "Registration not found.");
return "";
}
// Check if app was updated; if so, it must clear the registration ID
// since the existing regID is not guaranteed to work with the new
// app version.
int registeredVersion = prefs.getInt(PROPERTY_APP_VERSION, Integer.MIN_VALUE);
int currentVersion = getAppVersion(getApplicationContext());
if (registeredVersion != currentVersion) {
Log.i("tag", "App version changed.");
return "";
}
return registrationId;
}
private SharedPreferences getGCMPreferences(Context context) {
// This sample app persists the registration ID in shared preferences, but
// how you store the regID in your app is up to you.
return getPreferences(Context.MODE_PRIVATE);
}
private void registerInBackground() {
new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... params) {
String msg = "";
try {
if (gcm == null) {
gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
}
regid = gcm.register(SENDER_ID); // Here it returns empty string**
msg = "Device registered, registration ID=" + regid;
sendRegistrationIdToBackend();
// Persist the regID - no need to register again.
storeRegistrationId(MainActivity.this.getApplicationContext(), 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;
}
}.execute(null, null, null);
}
private void sendRegistrationIdToBackend() {
// Your implementation here.
}
private void storeRegistrationId(Context context, String regId) {
final SharedPreferences prefs = getGCMPreferences(context);
int appVersion = getAppVersion(context);
Log.i("tag", "Saving regId on app version " + appVersion);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(PROPERTY_REG_ID, regId);
editor.putInt(PROPERTY_APP_VERSION, appVersion);
editor.commit();
}
