答案 0 :(得分：0)
首先，只放置您的应用程序的日志。
其次，您尝试在未初始化时关闭进度对话框。
java.lang.NullPointerException: Attempt to invoke virtual
method 'void android.app.ProgressDialog.dismiss()' on a null object reference
我开始使用MainActivity.java:161
答案 1 :(得分：0)
您的代码中的某个位置的进度条上设置了dismiss（），但没有初始化它。
DO
if(progress!= null)
progress.dismiss()
