To start recognizing gesture in our application we have to add the GestureOverlayView to our XML layout file. Loading the gesture library and recognizing the gesture To copy the gesture file from the emulator, select it and click the “Pull a file from the device” button, marked with red in the screenshot below:ĭon’t forget to create a new folder called raw in the res directory of your project and copy there the gesture file.ģ. Navigate to /sdcard directory and copy the gesture file to your computer, for example on your desktop. (If you don’t have the FileExplorer tab available, add it from: Window -> Show View -> File Explorer). In order to do this, open the FileExplorer tab in the DDMS perspective.

We should import this file into our /res/raw project directory.

Start the Android Emulator and use the Gesture Builder application to create the “S” and “O” gestures:Ī gesture is always associated with a name, but the name does not necessarily have to be unique. Starting with version 1.6 and higher the Android Emulator includes a new application pre-installed, called Gestures Builder. The result will look like in the screenshot below: When a corresponding gesture will be recognized, a toast message will be shown. This tutorial will show you a proof-of-concept application how you can make use of Gesture API.
