Thank you very much Anke, I will try it!
Now I have another problem:
A few days ago I took my mobile phone to the technical service because the audio player stopped. They have checked it for a couple of weeks and it doesn't fail them. Now that I have it installed everything and it works perfectly. I have installed the app that I have created to open pdfs with the inventor and again when the mobile fails to play music.
Can this failure in audio reproduction be possible when installing something made with inventor?
Post your blocks or the (test) aia.
Checked: It seems that it is not the inventor's APP. Yesterday my audio player failed several times and I did not have my APP installed and had not installed it after a factory reset!
