28.5 Installing and Running the Gesture Builder Application
The easiest way to create a gestures file is to use an app that will allow gesture motions to be captured and saved. Although Google originally provided an app for this purpose, it has not been maintained adequately for use on more recent versions of Android. Fortunately, an alternative is available in the form of the Gesture Builder app developed by Manan Gandhi which is available from the Google Play Store at the following URL:

Note that the app works best on devices or emulators running Android 9.0 (API 28) or older.
