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?

Answer 1

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"  />
