推舉浏覽：Android中微信搶紅包插件道理解析及開辟思緒
搶紅包的道理都差不多，普通是用Android的幫助功效（AccessibilityService類）先監聽告訴欄事宜或窗口變更事宜來查找紅包症結字然後去模仿點擊或翻開紅包。
上面附上源碼，法式已完成主動搶紅包，鎖屏黑屏狀況主動解鎖亮屏，Android4.X測試經由過程。函數詳細功效請看具體正文。
注：在聊天界面收到紅包不會主動翻開，由於告訴欄沒有新聞提醒從而監聽不了，此時只需手動點一下便可。其他未知情形請自行用LogCat調試，源碼曾經有相干的調試信息。軟件僅供進修文娛。

accessibility_config.xml辦事設置裝備擺設內容以下
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android" android:accessibilityEventTypes="typeNotificationStateChanged|typeWindowStateChanged|typeWindowContentChanged" android:accessibilityFeedbackType="feedbackGeneric" android:accessibilityFlags="flagDefault" android:canRetrieveWindowContent="true" android:description="@string/desc" android:notificationTimeout="100" android:packageNames= "com.tencent.mm,com.tencent.mobileqq" />
個中description為幫助功效的描寫內容，packageNames為監聽的法式包名，此處只監聽微信和QQ的accessibilityEventTypes
以上所述是針對Android幫助功效AccessibilityService與搶紅包幫助的相干常識，願望對年夜家有所贊助。
