Can I set dynamically within an activity the preferred/default application that’s to be launched

  • 0

Can I set dynamically within an activity the preferred/default application that’s to be launched when I push the Home key? If that’s not possible, can I at least reset current defaults so that the chooser window re-appears? I tried to implement the latter by calling PackageManager.clearPackagePreferredActivities(“com.android.launcher”), but that doesn’t seem to do it(I gave my activity SET_PREFERRED_APPLICATIONS permission).

    Can I set dynamically within an activity the preferred/default application that’s to be launched when I push the Home key?

    No. There is no exposed API for this.

    If that’s not possible, can I at least reset current defaults so that the chooser window re-appears?

    Only if you are implementing the home screen that is the current default.

    I tried to implement the latter by calling PackageManager.clearPackagePreferredActivities(“com.android.launcher”)

    As the documentation for that method states, “An application can only clear its own package(s).”.
