Unable to add window ,is your activity running?

bug

修改方法如下

if(mProgressDialog != null && mProgressDialog.isShowing()) 
 mProgressDialog.show();

  @Override
  public void onDestroy() {
    super.onDestroy();
    if(mProgressDialog != null) {
      mProgressDialog.dismiss();
    }
    if(mAlertDialog != null) {
      mAlertDialog.dismiss();
    }
  }

public void showBox() {
    mActive = true;
    if (! ((Activity) mContext).isFinishing()) {
        mDialogBox.show();
    }
}
