java.lang.NullPointerException 空指针

[sjqnice]

从设置里操作完权限返回应用报空指针，由于这句progressDialog.showWithStatus("加载中",SVProgressHUD.SVProgressHUDMaskType.Clear); 引起的。

我通过下面方式解决了这个问题，不知道哪位大神还有其他更好的解决方案：
修改SVProgressHUD部分代码如下：
@OverRide
public void onAnimationEnd(Animation animation) {
new Handler().post(new Runnable() {
@OverRide
public void run() {
dismissImmediately();
}
});
}

十分感谢大佬

直接调用dismissImmediately试试 不要退出动画了
