App crashed when launch any app/ android 9
Hi. This is very strange bug, because app work is ok till I'm not launch, Youtube app. After launch app is crashed. If youtube already launched early and I'm open him, app is don't crash.
If app isn't in background and open Youtube, app don't crash.

full logcat: logcat.txt ... upd: Tested. App will crash if launch any Google App: Google Play, Youtube, Settngs, Instagram, even Calculator.. upd 2: on Android 7 it's work is ok
Created for test a new empty project with same problem.
(After launch app he create notify and move to background. If launch any app - he is crash)
Here apk: app-debug-apk.zip
Here source: testproject.zip
The most interesting thing is that before everything was ok. But now this problem is even with empty projects. I'm tryed update cordova, sdk/nsk, gradle and it's didn't help anyway.
cordova 8.1.2
gradle 4.10.2
sdk-platform-tools 28.0.2
sdk-tools 26.1.1
ndk 19.2.534
jdk jdk1.8.0_181
For test installed java and android tools to my centos server (I thought maybe trouble in my windows dev-environment)
- Created empty project
cordova create hello com.example.hello HelloWorld - Added platform
cd hello & cordova platform add - Installed plugin
cordova plugin add https://github.com/katzer/cordova-plugin-background-mode.git - Added
cordova.plugins.backgroundMode.setDefaults({ title: 'test', text: 'test', }); cordova.plugins.backgroundMode.enable(); cordova.plugins.backgroundMode.excludeFromTaskList(); cordova.plugins.backgroundMode.moveToBackground();afterthis.receivedEvent('deviceready');in js/index.js cordova build android- Downloaded and installed apk to my phone and take the same bag (App is work till I'm not start any other app)
Continue debugging. Tried to did empty project with plugin on virtual machine, but the same problem.
- App crashed only if use
cordova.plugins.backgroundMode.excludeFromTaskList();If use only "cordova.plugins.backgroundMode.moveToBackground();" app don't crash.
So, after that, just launch instagram and app crashed. Log

Sorry if I do it bad, never worked with java before :) I think, it's maximum what I can to do. Hope, someone help with it :)
@zutakamarikana Thank you for noticing that this issue only occurs with "excludeFromTaskList". I can confirm that this is indeed the case, at least on my Galaxy S9 (which is running Android 9) and Android 9 emulator. I was having the same issue but never tried running without "excludeFromTaskList". The fix for this should be quite simple -- to change following line in BackgroundModeExt.java
from:
if (am == null || SDK_INT < 21)
to
if (am == null || SDK_INT < 21 || SDK_INT > 27)
ty, it's disable the function "excludeFromTaskList" on Android 9. but still hope to find the best way :)
UPDATE:
It's looks like Android bag (or cordova)
Because, I'm did background function without plugin:
-
To AndroidManifest added
android:excludeFromRecents="true" android:autoRemoveFromRecents="true"(it's work like excludeFromTaskList but hide app all the time from launch) -
Then open file
\platforms\android\app\src\main\AndroidManifest.xmland add to 37 linemoveTaskToBack(true);(lt's work like movetobackground())
Launch app. It's start in background. All work fine till I'm not launch any other app and it's closed like with this plugin.
I could run on android 9 1 - Change ForegroundService.java 2 - Add permission to AndroidManifest.xml

else
startForeground(NOTIFICATION_ID, makeNotification());

NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_NONE);
chan.setLightColor(Color.BLUE);
chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
assert manager != null;
manager.createNotificationChannel(chan);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
Notification notification = notificationBuilder.setOngoing(true)
//.setSmallIcon(R.drawable.icon_1)
.setContentTitle("App is running in background")
.setPriority(NotificationManager.IMPORTANCE_MIN)
.setCategory(Notification.CATEGORY_SERVICE)
.build();
startForeground(2, notification);
}
2 - AndroidManifest.xml
Give permission ForegroundService
+1 I had the same problem in android9 (Pie). The app I serve requires "excludeFromRecents" Is there a solution to this problem?
@sarpherviz I tried the above method, but it was not resolved.
Is there any log or error when you debug your app over AndroidStudio IDE?
@sarpherviz it's fix of channels and it's already included to last version of plugin. And as say @MyoungboKim early it's didn't help anyway :/
I didn't found any way to fix it, so I'm rewrite half-app to java by using the service-plugin for cordova (https://github.com/Red-Folder/bgs-core )
I could run on android 9 1 - Change ForegroundService.java 2 - Add permission to AndroidManifest.xml

Give permission ForegroundService
It solve the app crash.
You can also add the permission to Ionic 3 / Cordova apps by adding this in your config.xml under android platform:
<platform name="android">
<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>
</platform>
Found same conclusion as @zutakamarikana
Created a cordova-android issue #https://github.com/apache/cordova-android/issues/851

Thanks !! It solves the crash
