權限拒絕：打開提供程序 com.android.providers.contacts.ContactsProvider2 Read_Contacts 並且我沒有寫權限

Question

我嘗試從 android 網站https://android-doc.github.io/training/contacts-provider/retrieve-names.html#Permissions構建檢索聯系人列表，並嘗試將其配置為 31 個目標 api。 我收到了這個錯誤

E / AndroidRuntime：致命異常：ModernAsyncTask＃1進程：com.example.contactlistandroid，PID：15844 java.lang.RuntimeException：執行doInBackground（）時發生錯誤原因：java.lang.SecurityException：權限拒絕：打開提供程序com .android.providers.contacts.ContactsProvider2 來自 ProcessRecord{b4e47ee 15844:com.example.contactlistandroid/u0a160} (pid=15844, uid=10160) 需要 android.permission.READ_CONTACTS 或 android.permission.WRITE_CONTACTS

這是我的主要活動
