基於無障礙服務實現自動跳過APP啓動頁廣告實現原理AccessibilityService模擬點擊java

一. res目錄下新建xml文件夾新建文件accessibility.xml

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeWindowStateChanged|typeNotificationStateChanged|typeViewTextSelectionChanged|typeViewClicked"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:canRetrieveWindowContent="true"
    android:accessibilityFlags="flagDefault|flagRetrieveInteractiveWindows"
    android:canRequestTouchExplorationMode="true"
    android:description="@string/app_name"
    android:notificationTimeout="100"/>

清單文件中service中配置引用文件

<service
            android:name=".SkipService"
            android:label="Automaticskip"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>
            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/accessibility" />
        </service>
複製代碼

清單文件權限以下：

<uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

三.獲取軟件啓動頁面跳過按鈕的id

打開安裝SDK目錄下tools文件夾 D:\webapp\SDK\android\tools找到monitor.bat雙擊打開

點擊跳過按鈕控件右側能夠看到控件的id爲com.netease.cloudmusic:id/c6b 這樣就獲得了控件的idweb

其餘軟件可能會遇到無id的時候能夠使用文字查找遍歷markdown

微博的是一張圖片。。。。暫時還不知道如何處理。。但願對大家有點啓發app
