Hey guys,
I'm currently working on a tutorial for an app of my university.
In order to introduce the app to the user, we want to show him some pictures.
I've decided to use a fragmentStatePagerAdapter in combination with the glide library, because I ran out of memory on previous implementations. Unfortunately my new implementation does not work. At the 14th picture (out of 16) I'm getting an oom-error from the glide library.

I can't find my error...
Is it right that glider automatically organizes the memory of it's images? If so, what am I doing wrong?
Here's some code.
1. The activity I start at the first start of the app.
[Activity(Label = "Tutorial", ScreenOrientation = Android.Content.PM.ScreenOrientation.Landscape)]
public class TutorialActivity : FragmentActivity {
private ViewPager pager;
private const int NUMBER_OF_IMAGES = 16;
protected override void OnCreate(Bundle savedInstanceState) {
base.OnCreate(savedInstanceState);
App.Init(this, savedInstanceState);
// Remove notification bar
Window.AddFlags(WindowManagerFlags.Fullscreen);
RequestWindowFeature(WindowFeatures.NoTitle);
// set content view AFTER ABOVE sequence (to avoid crash)
SetContentView(Resource.Layout.ActivityTutorial);
pager = (ViewPager)FindViewById(Resource.Id.pagerTutorial);
pager.Adapter = (new TutorialPagerAdapter(this, SupportFragmentManager));
}
protected override void OnDestroy() {
base.OnDestroy();
}
public override void OnBackPressed() {
if (pager.CurrentItem == 0) {
Finish();
} else {
pager.CurrentItem = (pager.CurrentItem - 1);
}
}
private class TutorialPagerAdapter : FragmentStatePagerAdapter {
private readonly String[] images;
public TutorialPagerAdapter(TutorialActivity parent, global::Android.Support.V4.App.FragmentManager fm) : base(fm) {
images = Enumerable.Range(1, NUMBER_OF_IMAGES)
.Select(i => $"Android_Tut_{GetIndexToken(i)}.png")
.ToArray();
}
private string GetIndexToken(int index) {
if (index < 10) {
Console.WriteLine("Index: " + index + " returned: " + "0" + index.ToString());
return "0" + index.ToString();
} else {
Console.WriteLine("Index: " + index + " returned: " + index.ToString());
return index.ToString();
}
}
public override Android.Support.V4.App.Fragment GetItem(int position) {
FragmentTutorial result = FragmentTutorial.NewInstance(images[position]);
Bundle bundle = new Bundle();
bundle.PutString(FragmentTutorial.IMAGE_FILE_NAME, images[position]);
result.Arguments = (bundle);
return result;
}
public override int Count => images.Length;
}
}
The fragment
public class FragmentTutorial : Android.Support.V4.App.Fragment {
// Define Bundle keys for the image public static string IMAGE_FILE_NAME = "file_name"; public FragmentTutorial() { } // Static factory method that creates and initializes a new tutorial fragment: public static FragmentTutorial NewInstance(String p_fileName) { // Instantiate the fragment class: FragmentTutorial fragment = new FragmentTutorial(); // Pass the image: Bundle args = new Bundle(); args.PutString(IMAGE_FILE_NAME, p_fileName); fragment.Arguments = args; return fragment; } public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Get image: string imgName = Arguments.GetString(IMAGE_FILE_NAME, ""); imgName = imgName.Replace(".jpg", "").Replace(".png", ""); View view = inflater.Inflate(Resource.Layout.FragmentTutorial, container, false); // Locate the ImageView within the fragment's container: ImageView imgView = (ImageView)view.FindViewById(Resource.Id.imageViewTutorial); // Glide Stuff int resourceId = (int)typeof(Resource.Drawable).GetField(imgName).GetValue(null); Glide.With(Activity).Load(resourceId).Into(imgView); return view; } public override void OnDestroyView() { base.OnDestroyView(); }}
Thanks for enduring my horrible format. Dont know why the code declaration on this post is not working properly.
