+## Android Support
+First, Android natively has this feature, you can easily enable it by setting `windowSoftInputMode` in `AndroidManifest.xml`. Check [here](https://developer.android.com/guide/topics/manifest/activity-element.html#wsoft).
+
+But if you want to use feature like `extraHeight`, you need to enable Android Support with the following steps:
+
+- Make sure you are using react-native `0.46` or above.
+- Set `windowSoftInputMode` to `adjustPan` in `AndroidManifest.xml`.
+- Set `enableOnAndroid` property to `true`.
+
+Android Suppor is not perfect, here is the support list:
