Protect Android application on rooted phone

I am going to create application and want to protect in case of jailbreak. Is there any process to detect whether device is rooted or not so that we can make application stop working when device is detected as rooted.

Any help will be appreciated.

Thanks in advance.

"jailBreaked means Rooted"

Here is a class that will check for Root one of three ways. 

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;
    }

}

First of all, there are no "JailBreaks" in Android. If you want to check whether a device is rooted you can use the search of stackoverflow for a suitable solution.
