I'm developing an App that can be Screen Pinned aka Corporate Owned Single Use aka Lock Task Mode.
If I pin it and then:
- I close it (killing it) and then I launch it again
- or after some code modification in android studio and then perform Run
- restart after pin and unpin
I get the following error:

This is my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xx.yyy">
<application
android:allowBackup="true"

android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">

android:resource="@xml/device_admin_receiver" />
<intent-filter>

<activity android:name=".activities.LauncherActivity">

</activity>
<activity android:name=".activities.StartActivity">

<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>
If I don't ever pin the app I can restart/upgrade&run it many times I want.
The nice thing is that is not even possible to uninstall the app because it has been configured as Device Owner, and so, it cannot be uninstalled unless a factory reset.
I dont understand how is possible that my activity disappears after an app restart. Can be something related to the intent category or action?
If anyone else encountered this behavior can tell me I will submit an issue to the bug report site.
Thanks.
EDIT 18/3
I think maybe this is happening because at a certain point, I kill the home category activity that in my case is the missing StartActivity in question, and it is not restarted even if I restart the app.
