我正在实现推送通知,但是在调用getToken时我收到了TIMEOUT异常.
我在这里为GCM设置了应用程序,而SENDER_ID正是提供的那个.此外,Server API密钥保存在后端部分.
是否有有限数量的getToken请求?在测试推送通知时,我最初几次尝试都没有问题.
new AsyncTask<Void, Void, Void>(){
@Override
protected Void doInBackground(Void... params) {
try {
InstanceID instance = InstanceID.getInstance(mContext);
String registrationId = instance.getToken(Constants.GCM_SENDER_ID,
GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
SharedPreferences sp = mContext.getSharedPreferences(Constants.TOKEN_DATA, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putString(Constants.REGISTRATION_ID, registrationId);
editor.commit();
NotificationsRegister.getInstance(mContext).register(registrationId);
} catch(IOException e) {
e.printStackTrace();
}
return null;
}
}.execute();
