这是我的第一个问题,希望不会被忽视.

申请发布于3个月前.通常应用程序在多个Android设备上测试并且工作正常,但有些客户遇到崩溃.

堆栈跟踪：

Past_map_fragm代码：

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

...

final TabSpec tabSpec = tabHost.newTabSpec("map").setIndicator("Map")

.setContent(new Intent(getActivity(), Past_mapactivityinstance.class));

...

}

我知道NoClassDefFoundError确实是一般错误.我无法弄清楚为什么应用程序在大多数Android设备上工作正常,但有些人遇到此错误.

表现：
