Android gets multiple recently taken photos from albums (Get photos stored by camera photo)

When you are working on a company project, you encounter the need to customize the grid view that displays your photos, showing the top 20 photos taken by the user recently with the camera.

I looked at the system provides the API, did not find a direct point to take pictures after the camera to store the path constant, if you know, please tell me, thank you!

Here is the stupid way I used, the main code snippet is as follows:

  Get SDcard Card path   string sdcardpath = environment.getexternalstoragedirectory (). ToString ();   contentresolver mcontentresolver = mainactivity.this.getcontentresolver ( );   cursor mcursor = mcontentresolver.query (MediaStore.Images.Media.EXTERNAL_CONTENT_ uri,     new string[]{mediastore.images.media._id,  mediastore.images.media.data},     mediastore.images.media.mime_type +  "=?  OR  " + MediaStore.Images.Media.MIME_TYPE + " = ",      new string[] {  "Image/jpeg",  "Image/png"  }, mediastore.images.media._id +   " desc"); //  sorted by Image ID in descending order   while  (Mcursor.movetonext ())  {       //  Print Log to view the value of the photo ID       long id =  Mcursor.getlong (Mcursor.getcolumnindex (mediastOre. images.media._id));       LOG.I ("mediastore.images.media_id=",  id +   "");            //  filter out unwanted images, Only get pictures in albums that store photos after taking pictures       string path = mcursor.getstring ( Mcursor.getcolumnindex (MediaStore.Images.Media.DATA));      if  ( Path.startswith (sdcardpath +  "/dcim/100media")  | |  path.startswith (sdcardpath +  "/dcim/camera/")         | |  path.startswith (sdcardpath +  "Dcim/100andro"))  {    log.i ("image  path= ",  path);     img_path.add (" file://" + path);       }  }  mcursor.close ();
