關鍵代碼似乎是：_Caused by：java.lang.SecurityException：Permission Denial：從ProcessRecord {b3e8b0d 2141：com.example.umairkhan.test1/u0a57}打開提供程序com.android.providers.contacts.ContactsProvider2（ pid = 2141，uid = 10057）需要android.permission.READ_CONTACTS或android.permission.WRITE_CONTACTS_ – EJK

由於錯誤提示

要求你必須在manifest文件添加權限android.permission.READ_CONTACTS或 android.permission.WRITE_CONTACTS

<uses-permission android:name="android.permission.READ_CONTACTS" /> 

<uses-permission android:name="android.permission.WRITE_CONTACTS" />

更多有關android-permissions訪問android developer

Permissions

希望這將有助於。

沒有它沒有...........仍然有錯誤 –

@umairkhan什麼是logcat後，你把這兩個權限。這次是相同的還是不同的錯誤？你能檢查一下嗎？ – KDeogharkar

不能把它放在評論因爲它太長 –
