Yesterday I downloaded the Code App on my iPad, I think for making c++ java it is the best. But if I run a normal java file it starts me, but if I try to put the package it just doesn't work. I try to put the same package title in the folder but it just doesn't work and I don't know how to fix it. Thanks in advance

There is a problem in name = "pieces"
if the studio is not giving you much error info try to clean and rebuild and see if that fixes your problem.

Can anyone tell what could be the solution of this problem? I added everything in gradle, manifest etc.
It might be ad layout too small to display in some devices

I have published my app on android, and now I'm facing a problem with the JSON response on some devices ?!
I think the error message is telling you that some servers don't return valid JSON (or at least returning something that your code/library cannot handle). You might want to add some error checking code that would address such conditions.
