小编use*_*815的帖子

我正在构建一个Android应用程序,它使用OSM数据为来自一组给定位置的用户提供路径.用户可以键入他们希望进入SearchView的位置,并且当用户键入搜索结果时,搜索结果将被缩小以缩小结果,然后他们可以从下拉ListView中选择目标.使用onQueryTextChange()完成此过滤.我正在使用ContentProvider从数据库中查询此数据并实现LoaderManager.LoaderCallbacks接口以重新查询ContentProvider并为要使用的适配器提供新数据.

所有这些都在绝大多数时间内完成,并且完全符合预期.但是,很少,应用程序将崩溃与以下堆栈跟踪.
