i want to do this ..

I get that you know what you are asking, but we don't.

Are you saying you want to write a Python app that:

1) receives messages from the Android system file picker?

or

2) opens the system file picker?

or

3) something else ?

I have three video player..in android os ..when I do click on video file through Android file manager a popup tell me choose video player ..by which I want to play that video...in general Kivy video player are not showing in that pop-up ...I want to play that video by Kivy video player through Android file manager ..by clicking on video file

[Robert Flatt]

As I understand it you want an app that receives messages from the Android system file picker.

To my knowledge there is no Python example of this.

Since there is no free lunch, this requires reading a lot of Android documentation, reading some Java, using pyjnius, and possibly some new features in p4a.

The link you referenced contains a link for a place to start https://developer.android.com/training/sharing/receive

The Android documentation is great, but you have to read a lot of it to understand what they are thinking.

The documentation on the Python side (pyjnius, p4a) is very poor.

I find that tasks like this involve a lot of trial and error; sometimes too much.

If you want teach yourself how to use Android and pyjnius I suggest starting with a simpler task.

I don't know basics of Java Android ...
if .. please tell me how do I start ..

Find an online tutorial you like.

Here is a simple example to get you started. It displays text strings shared by some other app.

You would have to extend this to sharing videos, not difficult but you will have to read the the referenced Android documentation and perhaps more. No whining about you don't know Android, time to start teaching it to yourself.

Read the comments.

When you are done, please consider sharing the enhanced app with the Group.

main.py

from kivy.app import App
from kivy.uix.label import Label
from android import mActivity,autoclass

'''
buildozer.spec:
android.manifest.intent_filters = intent_filter.xml

Requires:
./intent_filter.xml
See:
https://developer.android.com/training/sharing/receive#handling-content
'''

Intent = autoclass('android.content.Intent')

class MyApp(App):
    def handle_message(self):
        # This must happen during build()
        intent = mActivity.getIntent()
        if Intent.ACTION_SEND == intent.getAction():
            if "text/plain" == intent.getType():
                text = intent.getStringExtra(Intent.EXTRA_TEXT)
                if text:
                    self.text = text
       
    def build(self):
        self.text ='No message'
        self.handle_message()
        return Label(text=self.text)

    def on_pause(self):
        # This is a hack so that the app will respond
        # to a message after the app is paused.
        # Obviously in a real app this would have side effects
        #
        # TODO Figure out how Android thinks this case should be handled.
        return False

MyApp().run()

intent_filter.xml

   <intent-filter>
        <action android:name="android.intent.action.SEND" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="text/plain" />
    </intent-filter>

yes ..I have to read many things...then ..if I read java android ..so there no need of python Kivy .I can develop app using java android ..

[Robert Flatt]

This addresses the paused app case, replace the MyApp class with:

class MyApp(App):  
    def new_intent_handler(self,intent):

        if Intent.ACTION_SEND == intent.getAction():
            if "text/plain" == intent.getType():
                text = intent.getStringExtra(Intent.EXTRA_TEXT)
                if text:

                    self.label.text = text

    def build(self):
        self.label = Label(text='No message')
        self.new_intent_handler(mActivity.getIntent())
        activity.bind(on_new_intent=self.new_intent_handler)
        return self.label

Do whatever makes you happy.
