My setting value and code.

AndroidManifest.xml

...
android:name="com.test.MapActivity"
android:resizeableActivity="true"
android:supportsPictureInPicture="true"
android:configChanges="orientation|smallestScreenSize|screenLayout|screenSize"
android:exported="true"
...

MapActivity.java

public void enterPIP(){
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        ...
        PictureInPictureParams params = new PictureInPictureParams.Builder()
                .setAspectRatio(new Rational(width, height)).build();

        ...
        boolean supportsPIP =
                packageManager.hasSystemFeature(PackageManager.FEATURE_PICTURE_IN_PICTURE);
        if (supportsPIP) {
            Log.d("PIP", "*** Picture-in-Picture ***");
            enterPictureInPictureMode(params);
        } else {
            Log.d("PIP", "*** No support Picture-in-Picture ***");
        }
    }
}

APP is crashing after calling enterPictureInPictureMode(params);

It works in an activity with simple buttons, but not work in the MapActivity, which is composed with complicated elements.

Answer

Finally, I found out the problem! Another activity extends this MapActivity. I declared PIP configuration for this activity in the AndroidManifest, it can work. 😀
