This application does not support pin Windows

Question

Users are complaining that my application is not able to be pinned on their S7 Devices using Oreo. Neither Snapdragon nor Exynos. The error does apparently only happen since a certain point in time - but did not happen immediately after the Oreo update, and has not yet been observed on non-Samsung devices. I tried googling the error message This application does not support pin Windows, but found nothing relevant. What causes this error?

Some information about the app:

    android:noHistory="false"
    android:excludeFromRecents="true"
    android:launchMode="singleTop
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>

And the startup:

    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
    getSupportActionBar().hide();
    Window window = this.getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

It also seems like I can't find another app that acts like this.

Answer 1

just remove the following line from your manifest files and your app will run properly on samsung phones:

android:excludeFromRecents="true"
