Android 10 start activity from background not working, foreground() and unlock() not working

Android 10 start activity from background not working, foreground() and unlock() not working.

Yes, i confirm ANDROID 10 is restrictive on starting activity from background, not allowed on API 29 / ANDROID 10, you must go to SETTINGS → Apps → Your App → Advanced → “Show app on top”, and NOW will work.
Just test it on CORDOVA and emulate with an ANDROID 10 version. Send it to background and then after a few seconds try to bring it back with unlock() or foreground();

Thanks.

I worked out a temporary fix, is working perfect.

Change files:

→ BackgroundModeExt.java

    //look for execute function that starts with `public boolean execute(etc, etc)`
    //right under in switch(action){ etc }, add this:
        case "permissionontop":
            RequestPermission();
        break;


    //send user to settings panel where he must allow "app on top" option
    //it makes sure only for ANDROID 10+ versions
    private void RequestPermission() {

        if (SDK_INT < 29) {
            return;
        }

        Activity activity = cordova.getActivity();
        Intent intent = new Intent(ACTION_MANAGE_OVERLAY_PERMISSION);

        cordova.getActivity().startActivity(intent);
    }

→ background-mode.js
Add this function

/**
 * Set permission to run on top > API 29.
 *
 * @return [ Void ]
 */
exports.permissionOnTop = function()
{
    if (this._isAndroid)
    {
        cordova.exec(null, null, 'BackgroundModeExt', 'permissionontop', []);
    }
};

→ In your cordova project

//it will send the user to app settings to allow app on top
cordova.plugins.backgroundMode.permissionOnTop();

Hi
I get these error:

D/SystemWebChromeClient: file:///android_asset/www/index.html: Line 125 : Uncaught TypeError: cordova.plugins.backgroundMode.permissionOnTop is not a function

What do i make wrong ?

[b1tw0rker]

Got to make ich working.
But at least, in Android 10 the App: ACTION_MANAGE_OVERLAY_PERMISSION can not add new apps :-(
What is todo, that my app ist listed there also?

I can confirm that enabling "Show on top" permission on Android 10 makes it working
