I'm trying to download certain apps from the Internet but once they have downloaded I try to install it but it says cannot open file. I have the unknown sources option checked in the settings page

Does the file being downloaded end in the .apk file extension? Are you downloading from a legitimate 3rd party app store?

If you open Adobe, does it show up in the app, or is there a way to import it? What happens if you open Adobe and then tap the menu button?

If when you open Adobe it will not show up in the Files,

1) Try renaming the file. This can be done within a file manager.

2) Possibly the file is corrupted. Try deleting and redownloading.

Good luck!
