Stream you device's display to another android device. And control your device back from that device.
Note: For KitKat+ (Lollipop) devices, new MediaProjection APIs are available which do not require the app to be installed in /system partition. I've implemented this API in this demo.
Note : I haven't really been maintaining it lately as I am usually stuck with other things, and that RemoteDroid requires a bit of extra efforts to make it support new Android versions and devices. If you're someone who wants to modify it according to your needs, and can hire me as a freelancer, ping me at omerjerk@gmail.com. Thanks.
