I have created a children's app that has a child lock using a custom launcher, however I have one small problem. When the app is closed and the home button is pressed the dialog to select the default launcher is displayed. Is there are way to reset the default launcher when the app is closed?
You cannot make any particular app be the default. However, you could use PackageManager and setComponentEnabledSetting(), to disable your activity that has the HOME category. Re-enable that when the user wants to have the choice of using your home screen again.
