I want to edit a apk file so that I can edit its notification tone. I found the notification tone and changed it but after compiling it and installing it gives me a error "App not installed".
For decompiling used 7zip and changed the notification tone and then zipped it back. This is the first time I am editing a file. I am "NOOB", so "NOOB" guides only. Please also tell me where I am going wrong and how to correct it.
