Android : Getting error, java.lang.VerifyError

I am trying to Webview and with that i used 3rd party SDK. When i try to access Info info = AdvertisingIdClient.getAdvertisingIdInfo(MainActivity.this); it gives me error. Below is my Code:

public class MainActivity extends Activity {

    public MobileAppTracker mobileAppTracker = null;
    WebView webview;
    ProgressBar progressbar;
    String url = "http://www.trade-24.com/forex-secrets-lp?lName=1348&tag1=mobileapp&Ads_Server=102c178defae24bd76883edbf22069&Campaign_Id=2&Link_ID=688&UtmCreative=";

    @SuppressLint("SetJavaScriptEnabled")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initialize MAT
        MobileAppTracker.init(getApplicationContext(), "", "");
        mobileAppTracker = MobileAppTracker.getInstance();

        new Thread(new Runnable() {

            @Override
            public void run() {

                try {
                    Info info = AdvertisingIdClient.getAdvertisingIdInfo(MainActivity.this);
                    mobileAppTracker.setGoogleAdvertisingId(info.getId(), info.isLimitAdTrackingEnabled());
                } catch (IOException e) {

                    mobileAppTracker.setAndroidId(Secure.getString(getContentResolver(), Secure.ANDROID_ID));

                } catch (GooglePlayServicesNotAvailableException e) {

                    mobileAppTracker.setAndroidId(Secure.getString(getContentResolver(), Secure.ANDROID_ID));
                } catch (GooglePlayServicesRepairableException e) {
                    mobileAppTracker.setAndroidId(Secure.getString(getContentResolver(), Secure.ANDROID_ID));
                } catch (NullPointerException e) {
                    mobileAppTracker.setAndroidId(Secure.getString(getContentResolver(), Secure.ANDROID_ID));
                }
            }
        }).start();

        webview = (WebView) findViewById(R.id.webview);

        progressbar = (ProgressBar) findViewById(R.id.progress);

        webview.loadUrl(url);

        webview.getSettings().setJavaScriptEnabled(true);

        webview.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {

                MainActivity.this.setProgress(progress * 100);

                if (progress < 100 && progressbar.getVisibility() == ProgressBar.GONE) {
                    progressbar.setVisibility(View.VISIBLE);
                }

                progressbar.setProgress(progress);

                if (progress == 100 && progressbar.getVisibility() == ProgressBar.VISIBLE) {

                    progressbar.setVisibility(ProgressBar.GONE);
                }

            }

        });

        webview.setWebViewClient(new WebViewClient() {

            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

                Toast.makeText(MainActivity.this, "Oh no! " + description, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPageFinished(WebView view, String url) {

                progressbar.setVisibility(ProgressBar.GONE);

                super.onPageFinished(view, url);
            }

        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        mobileAppTracker.setReferralSources(this);
        // MAT will not function unless the measureSession call is included
        mobileAppTracker.measureSession();
    }
}

I have searched in stackoverflow, no answer solved my problem. I have already added library in libs folder and also added to Build Path and checked it too.
