Android的ACTION_MEDIA_SCANNER_SCAN_FILE不显示图像，直至重新启动？ [英] Android ACTION_MEDIA_SCANNER_SCAN_FILE not showing image until reboot?

问题描述

我目前正在开发一个Android应用程序，用户需要被存储在外部存储器设备上的照片，然后我想也得到了库扫描的文件到新的媒体添加到图库然而，这似乎并没有不更新，直到设备重新启动。

I am currently developing an Android Application where users take pictures which are stored in External Memory on the device then I am trying to also get the Gallery to scan the file to add the new media to the Gallery however this does not seem to update until the device reboots.

在code我现在用的就是如下：

The code I am using is as follows:

    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Log.v("INFO", mCurrentPhotoPath.toString());
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);

拍摄图片我的应用程序后，我可以验证它存在使用设备上的文件管理器应用程序，也记录它似乎它传递给媒体扫描仪

After taking a picture with my app I can verify it exists using a file manager app on the device and also Logging the file path it appears to be correct before passing it to Media Scanner

file:/storage/emulated/0/Pictures/JPEG_20140712_163043_1418054327.jpg

推荐答案

试试这个

context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
                  Uri.parse("file://" +
                  Environment.getExternalStorageDirectory())));

或使用 这个方法..
