Android 8.1 - invalid channel for service notification #393

maerlynflagg · 2018-08-01T09:24:36Z

i'm develope ionic app and there i'm used this plugin.

after opening my app and the app is loaded, i called the function "backgroundmode.enable()". after a short timespan app stopped with the issue:

invalid channel for service notification

after removing the usage of this plugin the app isn't stopped and runs all the time. all fine.

so, i checked this. i have added the plugin usage again and the exception came back. i removed it again, exception is gone

this is the full stacktrace, which is shown in Logcat (Android Studio):

    android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=null pri=-2 contentView=null vibrate=null sound=null defaults=0x0 flags=0x42 color=0x00000000 vis=PRIVATE)

I also spent long time to solve this problem.
I solved this problem with below github (fork version).

try below command.

$ ionic cordova platform rm android
$ ionic cordova platform rm ios
$ ionic cordova plugin add https://github.com/tushe/cordova-plugin-background-mode.git
$ npm install --save @ionic-native/background-mode

$ ionic cordova platform add android
$ ionic cordova platform add ios

Have similar issues with Android 8.1 however re-adding the platform didn't resolve it.
On Android P (Pixel 2) I receive the following error:
Issue: java.lang.RuntimeException: Unable to create service de.appplant.cordova.plugin.background.ForegroundService: java.lang.SecurityException: Permission Denial: startForeground from pid=17789, uid=10151 requires android.permission.FOREGROUND_SERVICE
So if I add the permission android.permission.FOREGROUND_SERVICE I get the fatal exception:
android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification

Looks like an update might be needed - maybe something like this? ([https://stackoverflow.com/questions/47531742/startforeground-fail-after-upgrade-to-android-8-1])

EDIT: thanks @writer0713 that version has the fixes, updating ForegroundService.java with the updates from that git fixed the issue!

Dont works in Android >= 8

@writer0713 This fixed the crash issue, but background plugin stopped working :(

@Gurjit-ONEBCG

Below changes in the cordova-plugin-background-mode worked for me. Crash issue is resolved as well as background plugin is working fine.

In ForegroundService.java made below changes:
a) Add below import statement:
import android.app.NotificationChannel;
b) Add below global variables:

public static final String NOTIFICATION_CHANNEL_ID_SERVICE = "de.appplant.cordova.plugin.background";
public static final String NOTIFICATION_CHANNEL_ID_INFO = "com.package.download_info";

c) Replace keepAwake() method with below code:

private void keepAwake() {
       JSONObject settings = BackgroundMode.getSettings();
       boolean isSilent    = settings.optBoolean("silent", false);
       if (!isSilent) {
           if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
               NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
               nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_SERVICE, "App Service", NotificationManager.IMPORTANCE_DEFAULT));
               nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_INFO, "Download Info", NotificationManager.IMPORTANCE_DEFAULT));
           } else {
               startForeground(NOTIFICATION_ID, makeNotification());
           }
       }

       PowerManager powerMgr = (PowerManager)
               getSystemService(POWER_SERVICE);
       wakeLock = powerMgr.newWakeLock(
               PowerManager.PARTIAL_WAKE_LOCK, "BackgroundMode");
       wakeLock.acquire();
   }

Add below in AndroidManifest.xml file:
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
In code where I invoked background mode plugin, used disableWebViewOptimizations option on activate:

cordova.plugins.backgroundMode.on('activate', function() {
       cordova.plugins.backgroundMode.disableWebViewOptimizations();
 });

Alternately, you can try #416 but do remember to add FOREGROUND_SERVICE permission in AndroidManifest

thanks!!! Work Great!!!
I have a question.
do I need do the changes everytime I compile my phonegap/android platform?

ziyaddin · 2019-01-25T00:04:30Z

@brauliofreire is it still working fine on Android 8+ phones?

brauliofreire · 2019-01-25T00:07:24Z

@brauliofreire is it still working fine on Android 8+ phones?

yes! I made tests in android 8.1 and it is working fine!!

@katzer FYI. I haven't tested @Bharat-Rayasam's solution yet but it can be useful for you to come up with stable solution.

I was able to solve it this way: irceline/aq-mobile-be#94 (comment)

Any chance on this solution be added to the main repo code?

@Bharat-Rayasam this was the best solution! My application now works like a charm! Thank you!

I had to make a slight change though.
this.backgroundMode.on('activate').subscribe(() => this.backgroundMode.disableWebViewOptimizations());

app2b · 2021-01-01T22:14:27Z

ForegroundService.java

I couldn't find the .java file, could you tell me where to find it?

karimslim · 2021-06-04T09:19:03Z

Hi,

You could add FOREGROUND_SERVICE permission in your app once without updating AndroidManifest everytime you build the app.

Add those lines to your config.xml to grant the missing permission:

<config-file parent="./" target="app/src/main/AndroidManifest.xml" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> </config-file>
