What I am doing wrong to get the UID?

To kill the process I used killBackgroundProcess Method of ActivityManager. It needs package name not the UID.

Please see this answer by @seanhodges for reference. Reading the whole thread might be helpful too.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
