In my application , we are opening local pdf using below link: (Why isn't my app on the list of apps to open txt file?). Its work fine for first local pdf, but if i click home key of device application goes background and i tries to open file explorer it redirects to application and onResume method gets called which shows Pdfreader activity default. I tried finishTaskOnLaunch , clearTaskOnLaunch , launchMode as singleTask , singleTop. Please need help.

You cannot override the homekey. The Home button is made by android to provide a solution to the users to exit from malicious applications that could harm their devices.

As the accepted answer from this post said: Overriding the Home button - how do I get rid of the choice?

So try to do what you want in a different way

close the file connection inside the onpause() method of your activity may fix your problem.

  • because you currently open it as a part of your activity.use the activity flag FLAG_ACTIVITY_NEW_TASK –  Dec 05 '13 at 11:15
