Question

I am developing an app that uses packagenames to start a Third Party App. I have done some research and found out that all apps can be started from a launcher intent. Are there anyone that knows how to do this from a click of a Button.

Answer 1

You can’t really ‘start applications’. You can try to get the Launch Intent from the 3rd party application if you know the packagename:

Intent intent = getPackageManager().getLaunchIntentForPackage("com.thirdparty.package");
startActivity( intent );
