Take Picture with Camera Android

Hi, Here I'm going to discuss about how to take picture with camera in android and set that picture to ImageView.

So first create one activity, I have given name as CameraActivity.java and the layout file for it is named as activity_camera.xml

Permission:
For using camera and to store picture on storage we need define permissions under manifest.xml

<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

activity_camera.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/activity_camera"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
    <ImageView
       android:id="@+id/imageView"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentTop="true"
       android:layout_centerHorizontal="true"
       android:layout_marginTop="150dp"
       android:src="@mipmap/ic_launcher"/>
    <Button        
      android:id="@+id/btuttonTakePic"        
      android:layout_width="wrap_content"        
      android:layout_height="wrap_content"        
      android:layout_alignParentBottom="true"        
      android:layout_centerHorizontal="true"        
      android:layout_marginBottom="100dp"        
      android:text="Take Picture"/>
</RelativeLayout>

CameraActivity.java
public class CameraActivity extends AppCompatActivity {

    ImageView imageView;
    Button buttonTakePicture;
    private final int CAMERA_PIC_REQUEST = 1001;
    private Uri outputUri;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);

        imageView = (ImageView) findViewById(R.id.imageView);
        buttonTakePicture = (Button) findViewById(R.id.btuttonTakePic);

        buttonTakePicture.setOnClickListener(new View.OnClickListener() {
            @Override            public void onClick(View view) {
                Long tsLong = System.currentTimeMillis() / 1000;
                final String timeStamp = tsLong.toString();

                Intent camera_intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                File file = new File(createImageFile(), timeStamp + "mypic.png");
                outputUri = Uri.fromFile(file);

                camera_intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outputUri);
                camera_intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION, ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                startActivityForResult(camera_intent, CAMERA_PIC_REQUEST);
            }
        });
    }

    public File createImageFile() {
        String fullPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/photos/";
        File dir = new File(fullPath);
        if (!dir.exists()) {
            dir.mkdirs();
        }
        return dir;
    }


// To resize bitmap to avoid OutOfMemoryException
    public static Bitmap resizeImageWithMax(Bitmap bitmap, Integer maxDimension) {
        Bitmap resizedBitmap = null;
        int originalWidth = bitmap.getWidth();
        int originalHeight = bitmap.getHeight();
        int newWidth = -1;
        int newHeight = -1;
        float multFactor = -1.0F;
        if (originalHeight > originalWidth) {
            newHeight = maxDimension;
            multFactor = (float) originalWidth / (float) originalHeight;
            newWidth = (int) (newHeight * multFactor);
        } else if (originalWidth > originalHeight) {
            newWidth = maxDimension;
            multFactor = (float) originalHeight / (float) originalWidth;
            newHeight = (int) (newWidth * multFactor);
        } else if (originalHeight == originalWidth) {
            newHeight = maxDimension;
            newWidth = maxDimension;
        }
        resizedBitmap = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
        return resizedBitmap;
    }


    @Override    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CAMERA_PIC_REQUEST && resultCode == Activity.RESULT_OK) {
            Bitmap bitmap = null;
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), outputUri);
            } catch (IOException e) {
                e.printStackTrace();
            }
            if (bitmap != null) {
                bitmap = resizeImageWithMax(bitmap, 640);
                imageView.setImageBitmap(bitmap);

                System.gc();
            } else {
                Toast.makeText(this, "Failed to load image from camera", Toast.LENGTH_SHORT).show();
            }
        }
    }

}
