Android Question How to check #FILENOTFOUND when loading image file?

FERNANDO SILVEIRA · Apr 27, 2018

Hello guys,

I have the following code:

B4X:

bg = LoadBitmapResize(File.DirAssets, wWordOK & ".jpg", ImageView1.Width, ImageView1.Height, True)

What happen if the file is missing?
I'd like to test file existance and if the image is not there, load a default image instead.

Same doubt (file not found) reading text from a file.

Regards,
Fernando

Just check if file exists before trying to access it.

B4X:

If File.Exists(File.DirAssets, wWordOK & ".jpg") then
   bg = LoadBitmapResize(File.DirAssets, wWordOK & ".jpg", ImageView1.Width, ImageView1.Height, True)
End if

Thanx Claudio,
That's exactly what I was looking for.

If you type "File." you'll see all methods the File object has.

But why check DirAssets?
It's filled at compile time, therefore you should know which files it contains.

I guess @FERNANDO SILVEIRA's point here is: how to avoid an error for trying to access a missing file. Not necessarily in assets folder...
