Why cannot I display images saved to an album on Android?

Source: Internet
Author: User

Today, I have been struggling for a long time. I use the Android api:
[Java]
Bitmap bitmap = imageMap. get (url );
MediaStore. Images. Media. insertImage (getContentResolver (), bitmap, "myPhoto ","");
Save the bitmap to the system album. The saved image cannot be found until the album is opened. However, after restarting the phone, you can find it in the album. After the study, we found that you need to refresh the album environment to the album after writing the photo into the album:
[Java]
SendBroadcast (new Intent (Intent. ACTION_MEDIA_MOUNTED, Uri. parse ("file: //" + Environment. getExternalStorageDirectory ())));
