React Native onActivityResult not work

I have a webview component of React Native. The webview should support input type is file, so I do it as:

File Upload in WebView

and the webview implements ActivityEventListener and override onActivityResult.But the onActivityResult not working.

The Code is

class RNWebView extends WebView implements ActivityEventListener {
protected class GeoWebChromeClient extends WebChromeClient {
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri> filePathCallback, FileChooserParams fileChooserParams) {
...
mActivity.startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);
return true;
}
}

public RNWebView(ReactContext reactContext, Activity activity) {
super(reactContext);
// Add the listener for `onActivityResult`
reactContext.addActivityEventListener(this);
...
}

@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent intent) {
// Your logic here
Log.d("Tanck", "requestCode:" + requestCode + "----" + "resultCode:" + resultCode);
}

}

Maybe late hope it helps.

native module's onActivityResult is called by ReactContext which is called by ReactInstanceManagerImpl which in 0.29 is called by ReactActivity. In the example above MyWb extends Activity not ReactActivity, so ReactInstanceManagerImpl is never called.

onActivityResult

ReactContext

ReactInstanceManagerImpl

ReactActivity

MyWb

ReactActivity

ReactInstanceManagerImpl

The solution is just in your activity's onActivityResult call ReactInstanceManager's onActivityResult since you already have your own ReactInstanceManager object reference.

onActivityResult

ReactInstanceManager

onActivityResult

The Activity you are launching React Native from should have an override like this:

// Manually pass along the `onActivityResult` event to React Native event listeners.
// We are not extending from `ReactActivity` so we need to do this manually.
//
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

mReactInstanceManager.onActivityResult( this, requestCode, resultCode, data );

}


onActivityResult

mReactInstanceManager.onActivityResult( ... )

ReactActivity
