如何解决java.lang.Throwable？

从SplashScreenActivity中，我调用另一个活动

SplashScreenActivity.java HorizontalNtbActivity.java

Logcat如下所示：

我这样做是为了检查互联网连接：-

显示您的isInternetConnection（）方法。可能重复的请尝试以下方法：Intent i=new Intent（this，HorizontalNtbActivity.class）；在onCreate内的方法之前也使用此关键字。我认为，以下两种方法都会使用此关键字……您可以使用注释掉这两种方法来调试它。@Amit当我尝试此意图时，I=new Intent（this，horizontalntbacitivity.class）；发现该案例错误，无法解决。

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