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

@SteveJG

The instructions in the ActivityStarter documentation are a little ambiguous

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 dat=vnd.youtube:nAPk9ycCbfc cmp=com.google.android.youtube/.PlayerActivity }

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

can someone give an example

How to inspect the log see also here

Capturing Device Logs using adb logcat

ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. In this post, we’ll discuss how to install and use ADB. Installation: ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE . Download…

to integrate I mean click on a button and open the application "zettle"

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?

[Anke]

Exactly as I showed in the first block.

[Anke]

[Anke]

Use of the broad package (App) visibility (QUERY_ALL_PACKAGES) permission -...

[patel]

Anke's solution is much better than Package Manager Extension
There is also a way with activity starter ?

@patel

There is also a way with activity starter ?

Yes there is.. for example ...

[patel]

Thanks, it runs for Ai2 apps, can I use the same sintax for others apps ?

[dora_paz]

Yes you can

Start an app from a second app by repeating the operation

Try this way [image]

Start an app from a second app by repeating the operation

Otherwise you could install Activity Launcher that will help you to find the packages and classes of all installed apps in your phone.

[patel]

Thanks, I think Anke's way is more simple

@Anke

I used a new extension that declares a required permission for Android 11+.

How can I export this extension from your project ?

[Gianluca_Giambri]

Hi thanks I tried your example and it works but where can I download the extension? Is there a way to send the total to be paid directly on the zettlz application?
