AUTHORITY删除邮件的价值是什么

Question

大家好日子!!!

我们可以使用CallLog.AUTHORITY删除通话记录。这是一个删除调用的实用方法......

public static void deleteCallLogsFromNative(Context context, long[] rowIds) {
    ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(
            rowIds.length);
    for (int i = 0, N = rowIds.length; i < N; i++) {
        operations.add(ContentProviderOperation
                .newDelete(CallLog.Calls.CONTENT_URI)
                .withSelection(CallLog.Calls._ID + " = ?",
                        new String[] { String.valueOf(rowIds[i]) }).build());
    }
    try {
        context.getContentResolver().applyBatch(CallLog.AUTHORITY,
                operations);
    } catch (Exception e) {
        Log.e(TAG,
                "Error while deleting calls from native: " + e.toString());
    }
}

您可以观察到，对于应用批处理操作，我们需要一个AUTHORITY，这里需要CallLog.AUTHORITY来删除通话记录。

同样，我还有另一种删除邮件的实用方法......

public static void deleteMessagesFromNative(Context context, long[] rowIds) {
    ArrayList<ContentProviderOperation> operations = new ArrayList<ContentProviderOperation>(
            rowIds.length);
    for (int i = 0, N = rowIds.length; i < N; i++) {
        long rowId = rowIds[i];
        operations.add(ContentProviderOperation
                .newDelete(Uri.parse("content://sms/"))
                .withSelection(BaseColumns._ID + " = ?",
                        new String[] { String.valueOf(rowId) }).build());
    }
    try {
       // here I need AUTHORITY value for deleting messages
    } catch (Exception e) {
        // TODO: handle exception
    }
}

现在我的问题是，AUTHORITY删除邮件的价值是多少？
