本文介绍了两种防止Android应用中Dialog导致崩溃的方法：一是通过try-catch捕获异常并处理；二是检查创建Dialog的上下文有效性，仅在有效时关闭Dialog。

办法

1、直接try catch，将崩溃阻止

 try {
        if ((this.mDialog != null) && this.mDialog.isShowing()) {
            this.mDialog.dismiss();
        }
    } catch (final IllegalArgumentException e) {
        // Handle or log or ignore
    } catch (final Exception e) {
        // Handle or log or ignore
    } finally {
        this.mDialog = null;
    }

虽然暴力，但至少不崩溃了。
2、判断创建该Dialog的上下文是否有效，在有效的情况才关闭Dialog。

public void hideProgress() {
    if(mProgressDialog != null) {
        if(mProgressDialog.isShowing()) { //check if dialog is showing.

            //get the Context object that was used to great the dialog
            Context context = ((ContextWrapper)mProgressDialog.getContext()).getBaseContext();

            //if the Context used here was an activity AND it hasn't been finished or destroyed
            //then dismiss it
            if(context instanceof Activity) { 
                if(!((Activity)context).isFinishing() && !((Activity)context).isDestroyed()) 
                    mProgressDialog.dismiss();
            } else //if the Context used wasnt an Activity, then dismiss it too
                mProgressDialog.dismiss();
        }
        mProgressDialog = null;
    }
}
