In Android file manager when I click on video file an popup is open and show all video player options so I can choose video player to play video file ...This is due to

Intent filter in AndroidManifest.xml

But problem is how to pass video file path in my Kivy video player widget ..? I was reading intent will help to pass data from one activity to another activity in same or two different apps ..But I don't know how to do that ?via pyjnius

Robert Flatt please help me ..

If I correctly understand the question, look at this example, it receives a video share and plays it:

https://github.com/RobertFlatt/Android-for-Python/tree/main/share_rcv

The intent filter is an xml file that is added to the Manifest with a Buildozer option.

Basically just set up a listener, this listens for the share, and when a share arrives it passes the contents to the rest of the app via a callback.

It is important the capabilities in the listener match those advertised to the OS in the intent filter.

The example copies the shared file using a method from SharedStorage. The copy is fast, but takes storage space.

If that is an issue in your app, presumably one might be able to redirect the shared stream but I have not tried that.

It is possible redirecting might take some trickery (or not?), but I really don't know (so don't ask).

The intent filter tells Android what types of file your app can use.

The actual file (to which you want the path) is specified by the other app, and passed as a uri to your app.

You can get the path from the uri.

Of course you don't want the path, because your app don't have permission to read the file specified by the path.

You want to open a stream with the uri, and do something with that.

All this is coded in the example I referenced.

here?

uri = intent.getParcelableExtra(Intent.EXTRA_STREAM)

print(uri)

No way for me to know. Things you might look at....

The code does not filter the action type, that might be it?

Maybe it is something about the way the sender sent the attachment?

I can't debug your code for you.

That is clever.

Clearly it wont work on 29+, but that is OK because we have the other method in that case.

It would be good to test on 28.

For 29+ api you are coping that file .. think if the video is very large in size !!

So this is not good solution..are you sure above code will not work on 29+ api ?

I don't have Android 10 physical Phone ..so I can't test .

Android only has one UI activity active at a time (except split screen) , the others are all paused.

When the file manager is active, Kivy app is paused (does not do anything, including listen for new intents)

So on_resume .....

Look at how the listener works when the app is first built and when the app is not paused (they are different cases, you found another case).

I updated storage.py , now works on Android 6.

Note there is now an additional directory storage_src and this is specified in .spec

FYI if you are testing, Uri structure can vary according to its source, for example Android Files creates different uris to a third party file manager.

Yes I saw that, I have been unable to replicate.

I assumed it was an artifact of the changes there, or the file manager used there.

Which is why I started testing with more than one file manager.

But I still could not replicate what is demonstrated in the video.

Can you demonstrate with the current code on GitHub?

Does it make a difference which file manager is used?

Looking at your code (and maybe I missed something, because debugging other people's code is not something that interests me) the listener will not be active because the bind does not occur because the __init__() of the ShareRcv class is not called, because ShareRcv() is not instantiated.

It looks like you have main.py from a different app. 😂
