[success] Android looking great! 👌

Platform(s)

Android

Current Behavior

In my app I have both outgoing + incoming share functionality. When I try to share anything to the same app, the plugin's Android implementation becomes stuck in some "in-progress" state, and subsequent share calls immediately fail with error:

Can't share while sharing is in progress

Expected Behavior

All subsequent shares from the app into same app work OK.

Code Reproduction

I've prepared reproduction repo - please check out https://github.com/dmitry-salnikov/capacitor-share-plugin-bug-reproduction

Other Technical Details

Android only, everything works OK on iOS.

Additional Context

The problem

• Android tries to launch MainActivity with the ACTION_SEND intent.
• Because launchMode="singleTask", Android doesn't create a new activity instance. Instead, it reuses the existing task and brings it to the front.
• Since the activity never finishes (it's the same instance), activityResult() is never called.
• This way, isPresenting flag isn't reset, and all subsequent calls to share() would throw error Can't share while sharing is in progress.

The solution

Handle incoming share intent in SharePlugin's code to reset isPresenting flag and resolve plugin call, e.g.:

@Override
protected void handleOnNewIntent(Intent intent) {
    if (isPresenting && intent != null && Intent.ACTION_SEND.equals(intent.getAction())) {
        PluginCall call = bridge.getSavedCall("activityResult");
        if (call != null) {
            call.resolve(new JSObject().put("activityType", ""));
        }
        isPresenting = false;
    }
}
