This project shows a bug some Android manufacturers (confirmed on Xiaomi devices) have with their forked Android (AOSP) code. This specific bug is if the user swipes away the app and taps on a notification. After the user presses the device's back button the app goes to the homescreen instead of following the app developer's intended back stack.
- Download the NotificationActivityBackstackExampleIssue.apk and install it on your Android device or emulator
you which to confirm the issue on.

- On Xiaomi devices include if the issue happens when “Display pop-up windows while running in the background” (older MIUI versions this is called “Start in background”) is enabled or disabled
- Optional - Logcat,
adb shell dumpsys activity activities, or any other useful outputs welcome to provide more details about the issue. - Optional - Video not required but helpful
This app creates a Notification with a PendingIntent that will open TargetActivity and put
MainActivity on the back stack. The parent is defined in the
AndroidManifest.xml of this app with android:parentActivityName
and the <meta-data> tag with name="android.support.PARENT_ACTIVITY".
This follows the guidance outlined by Android's "Start an Activity from a Notification" documentation for "Regular activity". Reference: https://developer.android.com/training/notify-user/navigation
Xiaomi ROM bug, NOT an Android AOSP bug
The back button behavior works in all cases except for Xiaomi devices when the app is swiped away and it's Xiaomi specific “Display pop-up windows while running in the background” (older MIUI versions this is called “Start in background”) permission is "Deny"(default) for the app.
