Is there a way to create a script or "app" to automatically input data into an already installed app. I.e Fill and submit a todo task in a todo app. Or fill a register form ?
In every device, there is a binary called
You can invoke it with from your application or even from adb:
$ adb shell input Usage: input [<source>] <command> [<arg>...] The sources are: mouse keyboard joystick touchnavigation touchpad trackball stylus dpad touchscreen gamepad The commands and default sources are: text <string> (Default: touchscreen) keyevent [--longpress] <key code number or name> ... (Default: keyboard) tap <x> <y> (Default: touchscreen) swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen) press (Default: trackball) roll <dx> <dy> (Default: trackball)
You can then navigate int the app using KeyEvent, click buttons, submit text to the focused element, etc.
