I'm still working on the MMS sending part.

Android - Get latest photos taken

I think this post https://stackoverflow.com/a/4495753/2014374 should help you finding your answer.

It used content resolver over Images.Media.EXTERNAL_CONTENT_URI and filters the results by getting the Media.BUCKET_ID from media bucket name "/DCIM/Camera"; Hope this helps.

How to get last image captured with camera in android?

Use this to get path of file from URI:

Uri selectedImageUri = data.getData();
selectedImagePath = getRealPathFromURI(selectedImageUri);

    public String getRealPathFromURI(Context context, Uri contentUri) {
  Cursor cursor = null;
  try { 
    String[] proj = { MediaStore.Images.Media.DATA };
    cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
  } finally {
    if (cursor != null) {
      cursor.close();
    }
  }
}

Cursor provides random read-write access to the result set returned by a database query.

getContentResolver () returns a ContentResolver instance for your application's package.

When you want to access data in a content provider, you use the ContentResolver object in your application's Context to communicate with the provider as a client. The ContentResolver object communicates with the provider object, an instance of a class that implements ContentProvider. The provider object receives data requests from clients, performs the requested action, and returns the results.

The Content Resolver includes the CRUD (create, read, update, delete) methods corresponding to the abstract methods (insert, delete, query, update) in the Content Provider class. The Content Resolver does not know the implementation of the Content Providers it is interacting with (nor does it need to know); each method is passed an URI that specifies the Content Provider to interact with.

MediaStore: The Media provider contains meta data for all available media on both internal and external storage devices. MediaStore.images contains meta data for all available images.

Swift - how to get last taken 3 photos from photo library?

Here's a solution using the Photos framework available for devices iOS 8+ :

import Photos

class ViewController: UIViewController {

    var images:[UIImage] = []

    func fetchPhotos () {
        // Sort the images by descending creation date and fetch the first 3
        let fetchOptions = PHFetchOptions()
        fetchOptions.sortDescriptors = [NSSortDescriptor(key:"creationDate", ascending: false)]
        fetchOptions.fetchLimit = 3

        // Fetch the image assets
        let fetchResult: PHFetchResult = PHAsset.fetchAssets(with: PHAssetMediaType.image, options: fetchOptions)

        // If the fetch result isn't empty,
        // proceed with the image request
        if fetchResult.count > 0 {
            let totalImageCountNeeded = 3 // <-- The number of images to fetch
            fetchPhotoAtIndex(0, totalImageCountNeeded, fetchResult)
        }
    }

    // Repeatedly call the following method while incrementing
    // the index until all the photos are fetched
    func fetchPhotoAtIndex(_ index:Int, _ totalImageCountNeeded: Int, _ fetchResult: PHFetchResult<PHAsset>) {

        // Note that if the request is not set to synchronous
        // the requestImageForAsset will return both the image
        // and thumbnail; by setting synchronous to true it
        // will return just the thumbnail
        let requestOptions = PHImageRequestOptions()
        requestOptions.isSynchronous = true

        // Perform the image request
        PHImageManager.default().requestImage(for: fetchResult.object(at: index) as PHAsset, targetSize: view.frame.size, contentMode: PHImageContentMode.aspectFill, options: requestOptions, resultHandler: { (image, _) in
            if let image = image {
                // Add the returned image to your array
                self.images += [image]
            }
            // If you haven't already reached the first
            // index of the fetch result and if you haven't
            // already stored all of the images you need,
            // perform the fetch request again with an
            // incremented index
            if index + 1 < fetchResult.count && self.images.count < totalImageCountNeeded {
                self.fetchPhotoAtIndex(index + 1, totalImageCountNeeded, fetchResult)
            } else {
                // Else you have completed creating your array
                print("Completed array: \(self.images)")
            }
        })
    }
}

Get last captured image?

After take photo:

MainActivity

 String filePath;
    @Override
        protected void onCreate(Bundle savedInstanceState) {   
        ...
        }

    private void onCaptureImageResult(Intent data) {
            Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);

      String fileName = "yourPhotoName" + ".jpg"

      filePath =  "pathOfMyAppImageFolder" + fileName;

      File destination = new File(filePath);

    FileOutputStream fo;
          try {
           destination.createNewFile();
           fo = new FileOutputStream(destination);
           fo.write(bytes.toByteArray());
           fo.close();
          } catch (FileNotFoundException e) {
           e.printStackTrace();
          } catch (IOException e) {
           e.printStackTrace();
         }
      }

      yourButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                Intent intent = new Intent(getApplicationContext(), AnotherActivity.class);
                intent.putExtra("filePath", filePath)
                startActivity(intent);

                }
            });

AnotherActivity

String filePath;
    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

    Intent intent = this.getIntent();

    filePath = intent.getStringExtra("filePath");

    File imgFile = new  File(filePath);

    if(imgFile.exists()){

        Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

        ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);

        myImage.setImageBitmap(myBitmap);

        }
     }

Take the last photo of the folder:

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

    List<File> files = getListFiles(new File("MyAppImageFolderPath")); 

    File imgFile = files.get(files.size());

    if(imgFile.exists()){

        Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

        ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);

        myImage.setImageBitmap(myBitmap);

        }
     }

 private List<File> getListFiles(File parentDir) {
    ArrayList<File> inFiles = new ArrayList<File>();
    File[] files = parentDir.listFiles();
    for (File file : files) {
        if (file.isDirectory()) {
            inFiles.addAll(getListFiles(file));
        } else {
            if(file.getName().endsWith(".jpg")){ //change to your image extension
                inFiles.add(file);
            }
        }
    }
    return inFiles;
}

How to show last taken image from specific folder?

To get the latest modified file in folder for specific extension

import org.apache.commons.io.FileUtils;
import org.apache.commons.io.comparator.LastModifiedFileComparator;
import org.apache.commons.io.filefilter.WildcardFileFilter;

...

    /* Get the newest file for a specific extension */
    public File getTheNewestFile(String filePath, String ext) {
        File theNewestFile = null;
        File dir = new File(filePath);
        FileFilter fileFilter = new WildcardFileFilter("*." + ext);
        File[] files = dir.listFiles(fileFilter);

        if (files.length > 0) {
            /** The newest file comes first **/
            Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_REVERSE);
            theNewestFile = files[0];
        }

        return theNewestFile;
    }

Addition

To get all files or only png and jpeg use

new WildcardFileFilter("*.*");
new WildcardFileFilter(new String[]{"*.png", "*.jpg"});
