How to send image from android gallery to react-native app?

问题

How do i share an image from android gallery to react-native app?

I've added an intent-filter to my AndroidManifest.xml:

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

How do i listen to the send intent?

Edit: I want to send an image from native image gallery to my react-native app, like sharing an image from gallery to instagram app.

回答1:

There is currently no builtin method to handle this. So i wrote a simple native android module by my own.

Finally i found an extension which supports ios and android.
