Canvas not build path in file apk

why is canvas not build path on file apk but build path on conect to companion?

Your question isn’t clear at all. What is the error message? Did you granted WRITE_EXTERNAL_STORAGE permission?

Notifier Show alert Error : Path because call Canvas1 save out put emty string. Why canvas is emty ?

Correctly it should read: Canvas image is not empty (string), but the image is not saved at all because the required permission was not granted.

Canvas component doesn’t ask for WRITE permission automatically as it should (this is a bug). So do it manually:


Thank you very much sire.

Please show block procedure canvas
