how to run installed .apk file from inside android application?

Question

I need to know how to open .apk file from inside my application. As I know, there is no any file explorer on Android OS, so I should use downloaded and installed program for this. I hope question is understandable. Thanks!

Answer 1

You can create an Intent using the action android.intent.action.ACTION_VIEW and a data URI pointing to the file.

This should open a dialogue asking the user to install the file (and warning them of the permissions it requires).

However - You do not have access to directly install an APK yourself.

Answer 2

If you mean install apk file after downloading, you can use this intent:

Intent installIntent= new Intent(Intent.ACTION_VIEW);
installIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
installIntent.setDataAndType(Uri.parse("file://" + apkFilePath),"application/vnd.android.package-archive");
startActivity(installIntent);
