I get a really strange error. I have a very simple Fragment in Android that should just display an imageView that I created using Inkscape whose name is "test_v1" and which is a png file.
The XML code looks like this:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/imageView2"
android:layout_width="200dp"
android:layout_height="200dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:srcCompat="@drawable/test_v1" />
</androidx.constraintlayout.widget.ConstraintLayout>
The Java code looks like this:
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import androidx.fragment.app.Fragment;
public class FR_Test extends Fragment {
public FR_Test() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_test, container, false);
}
}
When running the code (using 2 different emulators), I get a strange rendering error:

The really strange thing is that when I open the png file with MS paint and just draw one pixel (that you can't even see) and give the file another name "test_v2", the problem does not occur. Here you can see "test_v2"
Reminder: Can anyone explain this very weird behaviour or at least try to explain it?
