README.md

Introduction

Here we introduce how to use build-in camera to take a picture in both of Android and iOS devices.

Android

Take a picture.

iOS

Take, Save a picture and open build-in photo.

buildinCamera.java

private static final int TAKE_PICTURE = 1;
private Uri imageUri;

public void takePhoto(View view) {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Keep the data from build-in camera path.
    File file = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg");
    if (file.exists())
    {
        file.delete();
        file = new File(Environment.getExternalStorageDirectory() + File.separator + "image.jpg");
    }
    imageUri = Uri.fromFile(photo);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        // Camera request code.
        case TAKE_PICTURE:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = imageUri;
                getContentResolver().notifyChange(selectedImage, null);
                ImageView imageView = (ImageView) findViewById(R.id.ImageView);
                try {
                    Bitmap bitmap = android.provider.MediaStore.Images.Media.getBitmap(getContentResolver(), selectedImage);

                    imageView.setImageBitmap(bitmap);
                    Toast.makeText(this, selectedImage.toString(), Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
                Log.e("Camera", e.toString());
            }
            break;
        }
    }
}

buildinCamera.swift

class MyControlller UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet weak var iv: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let picker = UIImagePickerController()
        picker.delegate = self
        // Open the build-in camera.
        picker.sourceType = .Camera
        // Open the build-in photo roll.
        // picker.sourceType = .PhotoLibrary
        self.presentViewController(picker, animated: true, completion: nil)
    }
    
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String:AnyObject]) {
        // Set the picture you took to the image view.
        self.iv.image = info[UIImagePickerControllerOriginalImage] as? UIImage
        self.dismissViewControllerAnimated(true, completion: nil)
    }
}
