如何解决java.lang.Throwable？

Question

来自SplashScreenActivity的

我正在呼叫另一个活动。

SplashScreenActivity.java

if (CheckInternet.isInternetConnection(SplashScreenActivity.this)) {

    if (CheckInternet.isInternetConnection(SplashScreenActivity.this)) {
        Log.e(TAG, "device is online");
        //service for device validation from Api
        //  checkMobile();
        Intent i = new Intent(SplashScreenActivity.this, HorizontalNtbActivity.class);
        startActivity(i);
    } else {
        Log.e(TAG, "device is ofline");
    }
}

Horizo​​ntalNtbActivity.java

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_horizontal_ntb);//error found in this line
    checkPermissionNew();
    initUI();
}

Logcat如下：

 getService(), serviceName = multiwindow_service_v1 05-21 17:00:48.484 23034-23034/com.policynavtabbar D/FeatureProxyBase: FeatureProxyBase class constructor     getService(), serviceName = multiwindow_service_v1 05-21 17:00:48.505 23034-23034/com.policynavtabbar D/AccessibilityManager: setStateLocked: wasEnabled = false, mIsEnabled = false, wasTouchExplorationEnabled = false, mIsTouchExplorationEnabled = false, wasHighTextContrastEnabled = false, mIsHighTextContrastEnabled = false

我这样做是为了检查互联网连接： -

 public static boolean isInternetConnection(Context mcontext) {

    ConnectivityManager conMgr = (ConnectivityManager) mcontext.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = null;
    if (conMgr != null) {
        netInfo = conMgr.getActiveNetworkInfo();
    }
    if (netInfo == null) {
        new AlertDialog.Builder(mcontext)
                .setIcon(R.drawable.ic_sad)
                .setTitle("No Internet Connection")
                .setMessage("Please Enable Internet Connection Than Try Again.")
                .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                })
                .setCancelable(false)
                .show();

    } else {
        return true;
    }

    return false;
}
