Question

我在制作摄像机申请时,在拍照后(在照片中书写文件后),我想更新有关该装置的媒体档案,因此我使用媒体ScannerConnection(如以下代码)。但是,我无法看到该装置上的彩色应用中的图像。然而,我可以查看PC的图像(图像载于SD卡)。我没有什么东西?

MediaScannerConnection.scanFile(this, new String[] {pictureFile.toString()}, null, new MediaScannerConnection.OnScanCompletedListener() { public void onScanCompleted(String path, Uri uri) { Log.d("ExternalStorage", "Scanned " + path + ":"); Log.d("ExternalStorage", "-> uri=" + uri); } });

Answer 1

I think the following might be helpful (from the android-developers mailing list archive):

Oh man.. after 3 days of searching and bothering a couple people ive finally found the solution.. this one line of code:
sendBroadcast(new Intent(
    Intent.ACTION_MEDIA_MOUNTED,
    Uri.parse("file://" + Environment.getExternalStorageDirectory())));
发送了媒体开端的意向,以及搜索媒体的全外部储存,发现了新物品,删除了存在的东西。
