When you are working on a company project, you need to customize the grid view of the displayed photos to display the first 20 photos that you have taken with a recent camera.

I checked the API provided by the system and did not find the path constant pointing directly to storing photos after taking photos with a camera. If anyone knows, please let me know. Thank you!

The following is an example of my stupid method. The main code snippet is as follows:

// Obtain the path of the SDcard 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"); // sort by image ID in descending order while (mCursor. moveToNext () {// print the 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. You can only retrieve the image String path = mCursor in the album that stores the photo after taking the photo. getString (mCursor. getColumnIndex (MediaStore. images. media. DATA); if (path. startsWith (sdcardPath + "/DCIM/100 MEDIA") | path. startsWith (sdcardPath + "/DCIM/Camera/") | path. startsWith (sdcardPath + "DCIM/100 Andro") {Log. I ("image path =", path); img_path.add ("file: //" + path) ;}} mCursor. close ();
