日志清楚地说明了问题：

SecurityException: Permission Denial: opening provider
com.android.providers.contacts.CallLogProvider requires
android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS
检查清单文件中的权限。

根据stacktrace，问题实际上不在这些文件中。检查您的AndroidManifest.xml文件，并确保您具有访问联系人的适当权限。如果您仍然需要帮助，那么我建议您发布AndroidManifest.xml文件的源代码。这不是错误。我已经更改了它，并设置了正确的权限。我添加了：仍然是相同的堆栈跟踪？您是否在正确的位置添加了权限？权限位于清单标记中，而不是应用程序标记中。顺便说一句，与其添加答案，不如编辑您的问题并添加信息。我已经添加了manifest标记，但现在当我运行应用程序时，它说它已安装在emulator上，但图标没有显示在屏幕上。日志上没有错误很高兴能帮上忙！祝你的应用程序好运！
