GCM getToken () sends java.io.IOException: TIMEOUT

I use push notifications, but when I getToken, I get a TIMEOUT exception.

I installed the application for GCM here , and SENDER_ID is exactly the one that was provided. In addition, the API server key has been stored internally.

Is there a limited number of getToken requests? At first, I had no problems with several attempts when testing push notifications.

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();

Android Manifest:

 <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myexample" > <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.INTERNET"/> <permission android:name="com.myexample.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name="com.myexample.permission.C2D_MESSAGE" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <receiver android:name="com.google.android.gms.gcm.GcmReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="com.myexample" /> </intent-filter> </receiver> <service android:name=".helper.TutoriaGcmListenerService" android:exported="false" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> </intent-filter> </service> <service android:name=".helper.TutoriaInstanceIDListenerService" android:exported="false"> <intent-filter> <action android:name="com.google.android.gms.iid.InstanceID"/> </intent-filter> </service> ...

Dependencies added to the build.gradle module:

  • apply plugin: 'com.google.gms.google-services'
  • compile 'com.google.android.gms: play-services-gcm: 7.5. + '

Dependencies added to the build.gradle project:

  • classpath 'com.google.gms: google-services: 1.3.0-beta1'

I ran into this problem today and here is what I did to troubleshoot.

Firstly, I also used my own sender ID, trying to get a token. So instead, I tried using the sender ID from the examples Google provides getString(R.id.gcm_defaultSenderId)

As soon as I did this, I started getting another SERVICE_NOT_AVAILABLE error message

There are several SO questions that affect this, but the one that helped me was this one .

I turned off WiFi and used a 4G connection on my phone, and it worked with both gcm_defaultSenderId and my own sender ID.

Before registering, you should check if the google api is available with this piece of code or similar:

 GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance(); int resultCode = apiAvailability.isGooglePlayServicesAvailable(a); if (resultCode == ConnectionResult.SUCCESS) { //Do the getTokencall } else { //check the code }

You may not have received the SUCCESS result code. For example, if there is a pending google api update.

I had this problem and fixed it after trying to repeat.

It is possible that the Playback Services is not available until registration, this class may help you:

 public class PlayServicesValidator { private static final String TAG = PlayServicesValidator.class.getSimpleName(); private static final int PLAY_SERVICES_RESOLUTION_REQUEST = 9000; /** * Check the device to make sure it has the Google Play Services APK. If * it doesn't, display a dialog that allows users to download the APK from * the Google Play Store or enable it in the device system settings. */ public static boolean areAvailable(Context context) { GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance(); int resultCode = apiAvailability.isGooglePlayServicesAvailable(context); if (resultCode != ConnectionResult.SUCCESS) { return false; } return true; } /** * Only call if areAvailable was previously called and returned false * @param activity * @return */ public static boolean areRecoverable(Activity activity) { GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance(); int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity); if (resultCode != ConnectionResult.SUCCESS) { if (apiAvailability.isUserResolvableError(resultCode)) { return true; } else { return false; } } return true; } /** * Shows to the user a dialog to update play services * @param activity */ public static void recover(Activity activity) { GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance(); int resultCode = apiAvailability.isGooglePlayServicesAvailable(activity); if (resultCode != ConnectionResult.SUCCESS) { if (apiAvailability.isUserResolvableError(resultCode)) { apiAvailability.getErrorDialog(activity, resultCode, PLAY_SERVICES_RESOLUTION_REQUEST).show(); } } } }
