Android 判断手机是否有root权限

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/su"};
        for (String path : paths) {
            if (new File(path).exists()) return true;
        }
        return false;
    }
 
    private static boolean checkRootMethod3() {
        Process process = null;
        try {
            process = Runtime.getRuntime().exec(new String[] { "/system/xbin/which", "su" });
            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
            if (in.readLine() != null) return true;
            return false;
        } catch (Throwable t) {
            return false;
        } finally {
            if (process != null) process.destroy();
        }
    }
}

调用方法

if (isDeviceRooted()){
            Log.d(TAG, "onCreate: 你的设备可以获取root");
        }else {
            Log.d(TAG, "onCreate: 你的设备可以获取不能获取root");
        }
