Android应用程序在查询联系人后崩溃

执行以下代码后，我希望通过TextView resultText显示联系人列表

预期成果：

但是，它在执行游标c=cr.querycontacts，projection，null，null，null；后崩溃；。未显示错误日志EXED5。我已经在AndroidManifest.xml中添加了权限：

错误日志：

如何解决这个问题

---

感谢您的关注。

只需查询以下Uri:ContactsContract.CommonDataTypes.Phone.CONTENT\u Uri我已经尝试过，但结果仍然相同。代码：Uri contacts=contacts contract.commonDataTypes.Phone.CONTENT\u Uri；然后我们需要一个错误日志，只需尝试使用try-catch打印错误日志。尝试@pskink的方法。
