Integrate a second application (open an non App Inventor app from an App Inventor app)

pleae follow chapter "Discovering how to set the ActivityStarter properties" from the link provided earlier, here is it again Using the Activity Starter

Discovering how to set the ActivityStarter properties

If you want to start an app and you you don't have the source code or documentation, you might still be able figure out the package name and class name (and sometimes the intent) by launching the app and inspecting the Android system log.

For example, if you use the YouTube application to play a video, you'll see in the log:

I/ActivityManager( 86): Starting activity: Intent { act=android.intent.action.VIEW }

If you can find the "cmp=" string, then the ActivityPackage is the part before the slash, e.g., The ActivityClass is is the entire "cmp=" part, without the slash character, e.g., There may also in general be "dat=" information that should be specify as the DataUri property.

How to inspect the log see also here


Try this: launchZettle.aia (22.2 KB)

I used a new extension that declares a required permission for Android 11+.
So build the APK and try. (Make sure Zettle app is installed first.)



It runs well for launching my app, but how can I know the packageName for others apps?

Exactly as I showed in the first block.
