android 實現靜默安裝、卸載

標籤：des   android   io   ar   os   使用   sp   for   java   

方法1：【使用調用介面方法，由於安裝卸載應用程式的部分API是隱藏的，所以必須下載Android系統源碼，在源碼下開發並編譯之後使用MM命令編譯產生APK檔案】

安裝、卸載相關許可權<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
 
<uses-permission android:name="android.permission.DELETE_PACKAGES" />
 
<uses-permission android:name="android.permission.CLEAR_APP_CACHE" />
 
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
 
<uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />
 
 
 
方法2：【需要擷取root許可權或者和rom擁有一樣的簽名，即讓該apk以System的身份在系統中運行】
 
 private void test() {
   execCommand("system/bin/pm install -r " + "sdcard/xxx.apk"); // xxx.apk放置在內建儲存的根目錄下（mnt/sdcard/xxx.apk）
 
  // execCommand("system/bin/pm uninstall " +  PACKAGE_NAME); //PACKAGE_NAME為xxx.apk包名
  }
 
 public boolean execCommand(String cmd) {
   Process process = null;
   try {
    process = Runtime.getRuntime().exec(cmd);
    process.waitFor();
   } catch (Exception e) {
    return false;
   } finally {
    try {
     process.destroy();
    } catch (Exception e) {
    }
   }
   return true;
  }
 
 
 
其他方法：一些第三方jar包等方式
