Android: merging two diffrent application into one

问题

I have source code of two different application.In a separate Project I want to start an application with choice that if a user click option 1 then go to first application and if click on next button then to other application. I made a main page with buttons. Now how do I achieve this task.

回答1:

If you have to applications that should be started by a third (yours) then make sure those two are installed on your device and start them via Intent from your third.

回答2:

That's easy. Look at the /system/bin/am command (here: How to start an Android application from the command line?). You can run it from your code with Runtime.getRuntime().exec().

回答3:

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("PACKAGE NAME OF THE OTHER APPLICATION");
startActivity(LaunchIntent);

Replace "PACKAGE NAME OF THE OTHER APPLICATION" with the package name of the application that you want to run

回答4:

You can make a new Activity with 2 buttons and make it MainActvity. From button 1 call MainActivity of the 1st app and from 2nd button call MainActivity of 2nd app using Intent and startActivity().

And make necessary changes in AndroidManifest.xml
