问题 Changes like renaming a file triggered by an app only appear to the USB-MTP interface after reboot of the Android device or after you registered the new file at the MediaScanner them like this (see Trigger mediascanner on specific path (folder), how to?): file.renameTo(newFile); MediaScannerConnection.scanFile(context, new String[] { newFile.getAbsolutePath() }, null, null); USB-MTP is used to access the storage of an android device via USB.

I'm using adb to sync music on an android phone. Essentially, I rm the existing music directory and push replacement music files. I'd like to be able to use adb to force a rescan, so that the google music player (and other apps) works properly with the new songs and playlists. According to How can I refresh MediaStore on Android? you can force a rescan by broadcasting an appropriate intent. adb provides 'shell am broadcast', which would seem to allow me to force a rescan from adb. Alternatively I could run a rescan app or reboot, but I'd like to trigger the rescan from adb What adb command

How to trigger MediaScan on Nexus 7?

由 我们两清 提交于 2019-11-27 14:31:10
Because I want to make sure the MediaStore has the latest information without having to reboot I'd like to trigger the MediaScanner using the popular way I found on SO context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory()))); This works fine on my Samsung S2 w/ICS but not on my Nexus 7 w/JellyBean. Logcat shows this on my Nexus 7: WARN/ActivityManager(480): Permission denied: checkComponentPermission() owningUid=10014 WARN/BroadcastQueue(480): Permission Denial: broadcasting Intent { act=android.intent.action.MEDIA_MOUNTED

Android's Media Scanner: How do I remove files?

由 ﹥＞﹥吖頭↗ 提交于 2019-11-27 01:29:23
问题 I'm writing an app that removes files that may or may not be listed in any one of the types of media libraries such as music or pictures. While I can use the MediaScannerConnection.scanFile method to add files to the media library there doesn't seem to be any call to notify the service that the file has been removed. Sending it the path of the file that no longer exists doesn't result in the desired behavior either. How should I go about removing items from the library that no longer exist on

I want run the media scanner while capturing the image. After capturing, the image it is updated in grid view. For that I need to run media scanner.

I have found it best (faster/least overhead) to run media scanner on a specific file (vs running it to scan all files for media), if
