root权限是安卓最高的操作权限,俗称superuser,简称su,一般来说root过的手机,系统目录会有su目录和系统app目录中有Superuser.apk,或者kingroot、360Root、Root精灵、等apk。当然了,在安卓8系列中会使用magisk,文件名就不一样了。
下面是RootUtil文件,实现三种检测方法来判断是否有root
public class RootUtil {
public static boolean isDeviceRooted() {
return checkRootMethod1() || checkRootMethod2() || checkRootMethod3();
}
private static boolean checkRootMethod1() {
String buildTags = android.os.Build.TAGS;
return buildTags != null && buildTags.contains("test-keys");
}
private static boolean checkRootMethod2() {
String[] paths = { "/system/app/Superuser.apk", "/sbin/su", "/system/bin/su", "/system/xbin/su", "/data/local/xbin/su", "/data/local/bin/su", "/system/sd/xbin/su",
"/system/bin/failsafe/su", "/data/local/su", "/su/bin/
