Toga Android example

[pd4321]

I tried the example from "Toga Documentation, Release 0.4.9.dev28+g659868f03" on page 225.

from android.content import Intent
from android.net import Uri

intent = new Intent(Intent.ACTION_DIAL)
intent.setData(Uri.parse("tel:0123456789"))
def number_dialed(result, data):
    # result is the status code (e.g., Activity.RESULT_OK)
    # data is the value returned by the activity.

# Assuming your toga.App app instance is called `app`
app._impl.start_activity(intent, on_complete=number_dialed)

I get an error when I try to run it on my phone:

--------- beginning of crash
←[31mE/AndroidRuntime: FATAL EXCEPTION: main←[0m
←[31mE/AndroidRuntime: Process: com.example.helloworld, PID: 18472←[0m

What am I doing wrong? Thanks

Python doesn't have a new keyword.

intent = new Intent(Intent.ACTION_DIAL)

Looks like there's a stray usage of new in the docs. - that's a bug we need to clean up.

This has been fixed in #2952.

Without new I get a different error:

--------- beginning of crash
←[31mE/AndroidRuntime: FATAL EXCEPTION: main←[0m
←[31mE/AndroidRuntime: Process: com.example.helloworld, PID: 21881←[0m

The snippet in those docs isn't a complete example - it's an indicative snippet. You need to provide the instance of app that is appropriate for your app.

You also likely wouldn't have the Intent creation code at the top level of a module - it would be embedded in a method.

This works for me:

    async def openFileDialog(self, widget):
        from toga.platform import current_platform
        print("current_platform : ", current_platform)
        if current_platform == "android":
            from android.content import Intent
            from android.net import Uri

            intent = Intent(Intent.ACTION_DIAL)
            intent.setData(Uri.parse("tel:0123456789"))

            def number_dialed(result, data):
                    print(result, data)

            result = await self.app._impl.intent_result(intent)
