借助谷歌,并经过本大侠施展坑、蒙、拐、骗、偷五大绝技,终于成功实现在Delphi下获取Root权限并将其扩展为一个完整功能更加完整的TQAndroidShell记录,在华为荣耀2(Android 4.2)、Nubia Z5S(Android 4.4)测试通过。参考代码如下:

2、如果需要Root权限执行某些命令,调用TQAndroidShell.AskForRoot获得Root权限,否则忽略此步骤 if AShell.AskForRoot then begin ... end else //进入失败,手机未Root或者用户拒绝给予Root权限 ...; 3、调用Execute方法来执行命令行并获得返回的结果 AShell.Execute('ls /proc -l'); 4、如果要切换回普通账号模式,调用AShell.ExitRoot来返回当前普通账号模式 【注意】TQAndroidShell是一个记录,不需要手工释放(除非你是New生成的) } uses System.SysUtils, System.Diagnostics, Androidapi.Jni, Androidapi.JNIBridge, Androidapi.Jni.GraphicsContentViewText, Androidapi.Jni.JavaTypes, Androidapi.Helpers, FMX.Helpers.Android, FMX.Forms, FMX.Dialogs, qstring;

【提示】应修改AndroidManifest.template.xml文件,加入ACCESS_SUPERUSER权限,虽然不加暂时也没有太大的副作用。
