I can create an accessibility app for a certain app, like this,



Manifest XML



 <service android:name="com.my_company.my_app" android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
<intent-filter>
<action android:name="android.accessibilityservice.AccessibilityService"/>
</intent-filter>
<meta-data android:name="android.accessibilityservice" android:resource="@xml/serviceconfig"/>
</service>


serviceconfig XML



 <accessibility-service 
android:packageNames="com.other_company.some_app"
....


I am thinking of showing a small popup window that stays on apps, like this. The question is, can I show my popup window only when my accessibility target app com.other_company.some_app is running? That is, when com.other_company.some_app becomes foreground, I show the popup, and when the app is closed or becomes background, I hide the popup. It seems that my app is notified by onAccessbilityEvent when the app becomes foreground, but not when the app becomes background (pressing the home button).
