- onTrimMemory can cause an exception when attempting to release memory:

FATAL EXCEPTION: main
Process: com.titanium.test, PID: 7535

*TEST CASE* - Download an image first - Run app and select image from Downloads folder - Press back to exit app

Ti.Media.openPhotoGallery({
    success:function(event) {
        var image = event.media.imageAsResized(300, 300);
        console.log('resized image');
    }
});

NOTE: this is happening on Android 8.0
