Native RTL support in Android 4.2

To take advantage of RTL layout mirroring, simply make the following changes to your app:

1. Declare in your app manifest that your app supports RTL mirroring. Specifically, add android:supportsRtl=”true” to the element in your manifest file.
2. Change all of your app’s “left/right” layout properties to new “start/end” equivalents.
3. If you are targeting your app to Android 4.2 (the app’s targetSdkVersion or minSdkVersion is 17 or higher), then you should use “start” and “end” instead of “left” and “right”. For example, android:paddingLeft should become android:paddingStart.
4. If you want your app to work with versions earlier than Android 4.2 (the app’s targetSdkVersion or minSdkVersion is 16 or less), then you should add “start” and end” in addition to “left” and “right”. For example, you’d use both android:paddingLeft and android:paddingStart.
