问题描述
我现在用的是下载管理器
图像下载了我们的服务器,我把这些文件中的 externalFilesDir
。
我发送一个广播的意图,因为我不希望这些下载的图像出现在画廊。
sendBroadcast(新意图(Intent.ACTION_MEDIA_MOUNTED,Uri.parse(文件://+ context.getExternalFilesDir(空))));
我只测试了这个在我之前的Galaxy S3果冻豆4.3,这是工作,但是当我测试了奇巧4.4
崩溃的应用程序。
有没有更好的办法没有从下载管理器下载的文件不会出现在手机图库?

看来,谷歌正试图prevent在奇巧这一点。
看核心/ REST / AndroidManifest.xml中你会发现,广播 android.intent.action.MEDIA_MOUNTED
现在受到保护。这意味着它是只有系统能发送广播。
<保护广播机器人:名称=android.intent.action.MEDIA_MOUNTED/>
据你需要另一种方式来解决它这个职位。
如使用 MediaScannerConnection
或 ACTION_MEDIA_SCANNER_SCAN_FILE
。
MediaScannerConnection.scanFile(这一点,新的String [] {
file.getAbsolutePath()},
空,新MediaScannerConnection.OnScanCompletedListener(){
公共无效onScanCompleted(字符串路径,开放的URI)
{
}
});
I am using the DownloadManager
to download images off our server and I am placing the files in the externalFilesDir
.
I am send out a broadcast intent because I don't want these downloaded images to appear in the gallery.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + context.getExternalFilesDir(null))));
I only tested this on my Galaxy S3 Jelly Bean 4.3 prior and it was working, but when I tested it on KitKat 4.4
it crashes the app.
Is there a better way to not have the files downloaded from the DownloadManager not appear in the phone gallery?

It seems that google is trying to prevent this in KITKAT.
Looking at core/rest/AndroidManifest.xml you will notice that broadcast android.intent.action.MEDIA_MOUNTED
is protected now. Which means it is a broadcast that only the system can send.
<protected-broadcast android:name="android.intent.action.MEDIA_MOUNTED" />
According to this post you need another way to fix it.
Like using MediaScannerConnection
or ACTION_MEDIA_SCANNER_SCAN_FILE
.
MediaScannerConnection.scanFile(this, new String[] {
file.getAbsolutePath()},
null, new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri)
{
}
});
这篇关于java.lang.SecurityException异常:权限被拒绝:不允许发送广播android.intent.action.MEDIA_MOUNTED上奇巧只的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
