在我的应用程序中，我使用getContentResolver()访问通话记录和短信。这意味着我正在使用android content-provider。 getContentResolver()正在后台服务中运行。一切都还可以，但我的主要挑战是：每当我启动服务运行提取呼叫日志和文本消息的代码时，内容提供程序就会阻止我的主要执行线程。我试图将这些代码放在不同的执行线程中，但没有任何改变。
我真的需要帮助;我怎么能避免这种情况？因为应用程序在具有较小RAM和PROCESSORS的设备上不断提供ANR（应用程序无响应）消息。
如果您需要我显示代码，我准备粘贴，如果真的需要。
更新:(后台服务中的代码）
