I have a question that How to require another app to launch an app?
When I launch an app, it will show if the required app installed. If the required app haven't installed, it will show a button with a link to download the required app
For example: I launch POWERAMP FULL VERSION UNLOCKER, it will require POWERAMP TRIAL VERSION. If it has installed, it will show everything OK, if it hasn't installed, it will show "You haven't install POWERAMP TRIAL VERSION, CLICK HERE TO DOWNLOAD TRIAL VERSION"
Please instruct me, step by step and detailed
Thanks for reading...
