In the first build of Android 11 for developers, mention was made of the double tapping feature on the back of Pixel smartphones, which performs certain actions. For example, a double tap could launch Google Assistant or the camera, control music playback, etc. However, in subsequent releases of beta versions of Android 11, the mention of this feature disappeared from the firmware.
In June, Apple demonstrated similar functionality with the release of the first beta version of iOS 14. In addition, it became known that Xiaomi is also planning to implement the double-tap function in MIUI 12.
To the developer Kieron Quinn, known on the XDA-Developers forum under the nickname Quinny899, managed to port the double-tapping function as a regular application to almost any Android device. Device requirements: The device must support the ARMv8 architecture and run Android 7.0 Nougat or higher.
The app is called Tap tap and everyone can already try it. After installing the program, you must grant it permission in the Accessibility Service settings. In the Actions section, you can configure the action itself to double-tap (if you select several actions, they will be activated in turn). The Gates section sets up scenarios where double-tapping should not fire. And in Gestures, you can choose one of three smartphone models to test which of the profiles works most correctly with your device.
Based on user reviews, the app Tap tap works very well considering this is the first alpha version. Write in the comments your impressions of the program, if you have already tested it!
