hello,

I am currently conducting a study of restrictions on the different layers of the core android, made ??both by google and others.
My study deals with all versions that exist whether standard or custom.
can we share about these restrictions.

did you encountered these problems and in which part of core android ?

thank you for sharing your experience

regards,
