Android implements the WeChat automatic red packet snatching program, android implements red packet snatching

Android supports automatic red packet snatching, and android supports red packet snatching.

The service of automatic snatching of red packets is simply implemented. The principle is to find the corresponding View based on the keyword and then click it automatically. The AccessibilityService is mainly used as an auxiliary service, which can basically meet the function of automatic snatching of red packets. However, some logic needs to be optimized. For example, after a red packet is split, you must manually click the return key, in order to perform the next automatic snatching of red packets.
