Android應用程序在getContentResolver（）中崩潰查詢

請查找附加代碼以檢索傳入呼叫的聯繫人姓名。在這裏，我把這個數字硬編碼爲「123」。我在模擬器中添加了這個聯繫人。但是應用程序在getContentResolver（）。查詢中崩潰。請任何幫助。Android應用程序在getContentResolver（）中崩潰查詢

String number = "123"; 
// define the columns I want the query to return 
    String[] projection = new String[] { 
      ContactsContract.PhoneLookup.DISPLAY_NAME, 
      ContactsContract.PhoneLookup.NUMBER }; 

    // encode the phone number and build the filter URI 
    Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number)); 

    // query time 
    Cursor c = getContentResolver().query(contactUri, projection, null, 
      null, null); 

    // if the query returns 1 or more results 
    // return the first result 
    if (c.moveToFirst()) { 
     String name = c.getString(c 
       .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME)); 
     Log.i("Map", "Contact Name " + name); 
    }

你可以給logcat輸出日誌嗎？ – Ankit 2011-03-16 11:15:06

日誌已添加。請檢查 – indira 2011-03-16 11:25:53

好像你沒有添加讀取聯繫人的權限。檢查此鏈接：http://developer.android.com/reference/android/Manifest.permission.html#READ_CONTACTS – Ankit 2011-03-16 11:29:01

您可以給logcat輸出日誌。你需要一個上下文來調用getContentResolver（）。你是否在你的活動課或其他地方調用這個方法？

編輯：您需要添加權限才能從手機的通訊錄中讀取聯繫人。請點擊此鏈接： http://developer.android.com/reference/android/Manifest.permission.html#READ_CONTACTS

我認爲你的意思是將此添加爲評論。 – Reno 2011-03-16 11:10:13

我在活動類 – indira 2011-03-16 11:11:40

@Reno中打電話給我 - 對不起，我的錯誤，將在下一次照顧。 @sangita - 請你分享一下日誌。 – Ankit 2011-03-16 11:13:47

ERROR/DatabaseUtils(145): java.lang.SecurityException: Permission Denial: reading 
com.android.providers.contacts.ContactsProvider2 uri 
content://com.android.contacts/phone_lookup/9895318420 from pid=406, uid=10024 requires 
android.permission.READ_CONTACTS

該解決方案是正確的，錯誤日誌您發佈。將權限READ_CONTACTS添加到您的AndroidManifest您還需要一些其他相關權限，查看內容的文檔以查看哪些內容。 - 你需要的將取決於你如何使用API。
