Share a code example for Android to automatically grab red envelopes on WeChat

Simply implement the service of automatically grabbing red envelopes on WeChat. The principle is to find the corresponding View based on the keywords and then automatically click on it. Mainly using the auxiliary service AccessibilityService, it can basically meet the function of automatically grabbing red envelopes, but some logic needs to be optimized. For example, after opening a red envelope, you must manually click the return button to automatically grab the next red envelope.
