New to Android 4.x

[alfcen]

Hello

Dim Out As OutputStream
Out = File.OpenOutput(File.DirRootExternal, "skyatlas/" & pngfile & ".png", False)
Canvas1.Bitmap.WriteToStream(Out, 100, "PNG")
Out.Close

works fine with a 640x960px phone running Android 2.2, but does not
write any file with a tablet 1280x800px running Android 4.03. Tried JPEG, too, but no change.

Anybody more familiar with Android 4.03 and its possible glitches?

Android 4.x virtually bombards me with out-of-memory errors, while the
2-years old phone never complains. Time to care about memory sensitive programming, such as clearing bitmaps and canvases... the better practice, though.

Can you post the full error message from the logs?

There is no error message.
BTW, File.Copy works.

You can try setting android:largeHeap="true" in your Manifest file, which will increase the available heap size for the app, for Android 3.0 and above devices

Thanks a lot for throwing this in, Inman, I'll definitely try it.
