[@capacitor/share] "Can't share while sharing is in progress" when sharing to the same app on Android
还没有人认领这个 Issue。

调研方向
从 Android SharePlugin 实现开始，跟踪 share()、activityResult()、isPresenting 和 handleOnNewIntent()，注意 MainActivity 如何为 ACTION_SEND 重用。使用链接的示例应用重现该问题，然后验证传入的 share 会重置进行中的状态，并且后续 share 能够成功。

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
MainActivitywith theACTION_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,
isPresentingflag isn't reset, and all subsequent calls toshare()would throw errorCan'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;
}
