Question

我打算创建应用程序，并希望在越狱的情况下保护。是否有任何流程可以检测设备是否 rooted ，以便我们可以在检测到设备为root时使应用程序停止工作。

任何帮助将不胜感激。

提前致谢。

“jailBreaked意味着扎根”

这是一个将检查Root三种方法之一的类。

public class Root {

    private static String LOG_TAG = Root.class.getName();

    public boolean isDeviceRooted() {
        if (checkRootMethod1()){return true;}
        if (checkRootMethod2()){return true;}
        if (checkRootMethod3()){return true;}
        return false;
    }

    public boolean checkRootMethod1(){
        String buildTags = android.os.Build.TAGS;

        if (buildTags != null && buildTags.contains("test-keys")) {
            return true;
        }
        return false;
    }

    public boolean checkRootMethod2(){
        try {
            File file = new File("/system/app/Superuser.apk");
            if (file.exists()) {
                return true;
            }
        } catch (Exception e) { }

        return false;
    }

    public boolean checkRootMethod3() {
        if (new ExecShell().executeCommand(SHELL_CMD.check_su_binary) != null){
            return true;
        }else{
            return false;
        }
    }
}



public class ExecShell {

    private static String LOG_TAG = ExecShell.class.getName();

    public static enum SHELL_CMD {
        check_su_binary(new String[] {"/system/xbin/which","su"}),
        ;

        String[] command;

        SHELL_CMD(String[] command){
            this.command = command;
        }
    }

    public ArrayList<String> executeCommand(SHELL_CMD shellCmd){
        String line = null;
        ArrayList<String> fullResponse = new ArrayList<String>();
        Process localProcess = null;

        try {
            localProcess = Runtime.getRuntime().exec(shellCmd.command);
        } catch (Exception e) {
            return null;
            //e.printStackTrace();
        }

        BufferedWriter out = new BufferedWriter(new OutputStreamWriter(localProcess.getOutputStream()));
        BufferedReader in = new BufferedReader(new InputStreamReader(localProcess.getInputStream()));

        try {
            while ((line = in.readLine()) != null) {
                Log.d(LOG_TAG, "--> Line received: " + line);
                fullResponse.add(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        Log.d(LOG_TAG, "--> Full response was: " + fullResponse);

        return fullResponse;
    }

}

首先，Android中没有“JailBreaks”。如果要检查设备是否已植根，可以使用search of stackoverflow获取合适的解决方案。
