How to take a photo, save it and get the photo in Android

Question

I've been searching the simple example to take a photo, and save it using URI and retrieve the photo for image processing , I've tried lot of example code, but none of them went smoothly.

Is there anyone have the example code?

Solution 1

define a variable like this

protected static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;

Use the code for calling camera from android.

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"fname_" +        
                        String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

and in the class calling this override the onActivityResult function and enter the code below.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (resultCode == RESULT_OK) {
        if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

            //use imageUri here to access the image

            Bundle extras = data.getExtras();

            Log.e("URI",imageUri.toString());

            Bitmap bmp = (Bitmap) extras.get("data");

            // here you will get the image as bitmap


        } 
          else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
           } 
         }


    }

there are several example to capture image and store it and open it...

1. Android Camera API - Tutorial

2. Android Developers

3. Camera Example on Github

4. Another Example

Solution 3

I had the same problem.

I was testing some codes from the internet, and couldn't find any. Then, I studied some basics codes from developer.android. After that, I mixed two different codes and my one worked! Here it goes!

public class MainActivity extends AppCompatActivity {

    static final int PICTURE_RESULT = 1;
    String mCurrentPhotoPath;
    ContentValues values;
    private Uri file;
    ImageView imageView;
    Bitmap help1;

    ThumbnailUtils thumbnail;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        imageView = (ImageView) findViewById(R.id.imageView);
        values = new ContentValues();
    }

    public void launch_camera(View v) {
        // the intent is my camera
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        //getting uri of the file
        file = Uri.fromFile(getFile());

        //Setting the file Uri to my photo
        intent.putExtra(MediaStore.EXTRA_OUTPUT,file);

        if(intent.resolveActivity(getPackageManager())!=null)
        {
            startActivityForResult(intent, PICTURE_RESULT);
        }
    }

    //this method will create and return the path to the image file
    private File getFile() {
        File folder = Environment.getExternalStoragePublicDirectory("/From_camera/imagens");// the file path

        //if it doesn't exist the folder will be created
        if(!folder.exists())
        {folder.mkdir();}

        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_"+ timeStamp + "_";
        File image_file = null;

        try {
            image_file = File.createTempFile(imageFileName,".jpg",folder);
        } catch (IOException e) {
            e.printStackTrace();
        }

        mCurrentPhotoPath = image_file.getAbsolutePath();
        return image_file;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if(requestCode == PICTURE_RESULT) {
            if(resultCode == Activity.RESULT_OK) {
                try {
                    help1 = MediaStore.Images.Media.getBitmap(getContentResolver(),file);
                    imageView.setImageBitmap( thumbnail.extractThumbnail(help1,help1.getWidth(),help1.getHeight()));
                }catch (Exception e){
                    e.printStackTrace(); 
                }
            }
        }
    }
}

the XML files just have a Button and a ImageView and do not forget to declare in your android manifest the permissions:

<uses-feature android:name="android.hardware.camera"    android:required="true" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"  />

Do you realise, that with the code you have supplied, you are saving the image full sized to the stated uri, BUT, you are retrieving the reduced sized image from the extras, and creating the bitmap from that reduced size image?

[Pramod J George]

I am retrieving the image from the uri as full sized. do you want reduced image

[onexf]

@paulkayuk how do i retrieve a full sized image image instead of a compressed one?

[JPhi Denis]

Bitmap bmp = (Bitmap) extras.get("data") is the way to get the thumbnail

[Daniel Dees]

Does anyone know how to get the full-sized image? I would really like to know. I've been searching through stackoverflow threads for a while now and only coming up on these 7 year old threads of people having the same issue with no response...
