How to take pictures without saving / displaying image - android

I'm working with eclipse to develop a custom camera app for android. I've figured out how to display the preview of the camera, but I can't figure out how to take a picture without saving the image. When a picture is taken, I don't want to save the image or display it to the screen, I simply want it saved to a data type that I can use within the app and overwrite when another picture is taken.
Edit:
public class MainActivity extends Activity {
private Camera mCamera;
private CameraPreview mCameraPreview;
private Bitmap picture;
private static Uri mImageCaptureUri;
private static Bitmap photo = null;
private byte[] image;
private int PICK_FROM_CAMERA = 1;
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
#Override
protected void onCreate(Bundle savedInstanceState) {
releaseCameraAndPreview();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mCamera = getCameraInstance();
mCameraPreview = new CameraPreview(this, mCamera);
FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);
preview.addView(mCameraPreview);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_OK) return;
else{
Bundle extras = data.getExtras();
if (extras != null) {
photo = extras.getParcelable("data");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
image = bos.toByteArray();
}
File f = new File(mImageCaptureUri.getPath());
if (f.exists()){
f.delete();
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
//creates camera class for functions
private Camera getCameraInstance() {
Camera camera = null;
try {
camera = Camera.open();
} catch (Exception e) {
Log.v("Schweigen", "camera will not open");
}
return camera;
}
//releases camera on completion
private void releaseCameraAndPreview() {
if (mCamera != null) {
mCamera.release();
mCamera = null;
}
}
ShutterCallback shutterCallback = new ShutterCallback() {
public void onShutter() {
Log.v("Schweigen", "onShutter");
}
};
/** Handles data for raw picture */
PictureCallback rawCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
Log.v("Schweigen", "onPictureTaken");
}
};
/** Handles data for jpeg picture */
PictureCallback jpegCallback = new PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
//picture = BitmapFactory.decodeByteArray(data , 0, data.length);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
};
}

Make a Uri from the picture.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
Uri uriSavedImage=Uri.fromFile(new File(Environment.getExternalStorageDirectory().toString()+"/ImagesFolder/image.jpg"));
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
Edit: After that you may store it in a byte[].
As I told you, you have to get the the Intent from the Camera and set it to a Uri:
private static Uri mImageCaptureUri;
private static Bitmap photo = null;
private byte[] image;
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mImageCaptureUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"tmp_avatar_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_OK) return;
else{
Bundle extras = data.getExtras();
if (extras != null) {
photo = extras.getParcelable("data");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
image = bos.toByteArray();
}
File f = new File(mImageCaptureUri.getPath());
if (f.exists()) f.delete();
}
}

The API to directly take a picture is here.

Androind ImageView in Fragment

I am trying to put an image on my fragment, but the image is not showing up. I am certain that it was working just yesterday but now it is not. Any help is appreciated.
This code is in my Fragment:
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
mUser = (User) getArguments().getSerializable(ARGS_USER);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.fragment_picture_picker, container, false);
mImageView = v.findViewById(R.id.imageView);
mSelectImageButton = v.findViewById(R.id.select_image);
mSelectImageButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, IMG_REQUEST);
}
});
return v;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == IMG_REQUEST && resultCode == Activity.RESULT_OK && data != null){
Uri path = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), path);
mImageView.setImageBitmap(bitmap);
mImageView.setVisibility(View.VISIBLE);
mUser.setProfilePicture(bitmap);
}catch(IOException e){
e.printStackTrace();
}
}
}
Actually you are not using the Volley. Please change the heading of your question. You are accessing the Gallery and showing the image inside the imageView. Use the below code for accessing the image from camera as well as gallery.

action is like what you want to do. ACTION_REQUEST_GALLERY and ACTION_REQUEST_CAMERA use some integer constants like 100 and 101. profileImage is your ImageView.

I need to capture Image and display it in another activity

I have an activity that starts the camera API.
I want to press the button (named by id "cptr_1") and take a picture and display it in another activity (PhotoPreview.class) where I can add photo effects.
I just need the code for:
ImageButton capture_1 = (ImageButton)findViewById(R.id.cptr_1);
capture_1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
And then how to transfer that image to PhotoPreview.class
You can take photo with the camera app of the device.
So when you click:
static final int ImageValue= 1;
ImageButton capture_1 = (ImageButton)findViewById(R.id.cptr_1);
capture_1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takepic = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takepic.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takepic, ImageValue);
}
}
});
Once capture is completed get the image back from the camera application
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == ImageValue && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
}
}
Then send Bitmap to another activity.
Inside the activity that starts the camera API write:
Intent intent = new Intent(this, PhotoPreview.class);
intent.putExtra("GetBitmap", bitmap);
Inside PhotoPreview.class write:
Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("GetBitmap");
Also you may need to add those permissions to Android Manifest
<uses-feature android:name="android.hardware.camera"
android:required="true" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
either you can use an Intent to take picture or use a custom camera class
for camera intent for custom camera class
if u already have a custom camera class, you can use this code`Camera cam = Camera.open(cameraId);
capture_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
try {
cam.takePicture(null, null, mPicture);
} catch (Exception e) {
}
}
});
private PictureCallback mPicture = new PictureCallback() {
public void onPictureTaken(final byte[] data, Camera camera) {
try {
File mediaFile = new File("file path/filename.jpg");
FileOutputStream fos = new FileOutputStream(mediaFile);
fos.write(data);
fos.close();
cam.startPreview();
} catch (Exception e) {
}
}
};`

Take picture and display in other activity with API Demo

I've been following the Camera API Demo from the android developer site. After fixing alot of stuf i've come to my last problem. I want to use the picture i've just taken and display it in another activity (like when after you take a picture you first gotta accept it or redo it style).

How do i get the image taken in the above class and transfer it to my new activity?
EDIT SOLUTION OF MY OWN :
I remembered that i had a method that would create the directory for my image, so i knew the location. Only trick was to get the filepath. And because the method getOutputMediaFile was saved in a File I just had to getAbsolutePath() and sent it with the intent :
String filepath = pictureFile.getAbsolutePath();
Intent edit = new Intent(TakePhoto.this, EditPhoto.class);
edit.putExtra("filepath", filepath);
startActivity(edit);
finish();
Then in the other activity i just get it like this and display it:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.bijsnijden);
Intent myIntent = getIntent();
imagePath = myIntent.getStringExtra("filepath");
documentType = myIntent.getStringExtra("documentType");
ImageView imageView = (ImageView) findViewById(R.id.Image);
imageView.setImageBitmap(BitmapFactory.decodeFile(imagePath));
}
Convert it to a Byte array before you add it to the intent, send it out, and decode.
//Convert to byte array
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Intent in1 = new Intent(this, Activity2.class);
in1.putExtra("image",byteArray);
Then in Activity 2:
byte[] byteArray = getIntent().getByteArrayExtra("image");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

Capture and display image with custom camera app

It's bugging me for few days know. Problem is that I don't know if I'm going in right direction.
My starting activity is ImageDisplay class which calls startActivityForRestult for CustomCamera activity. After picture is taken user is returned to ImageDisplay and capture image should be displayed, but its not. What am I doing wrong?
Second thing, I guess its really important, at which point camera should be released?
ImageDisplay:
public class ImageDisplay extends Activity{
ImageView imageHolder;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.al_imagedisplay);
imageHolder = (ImageView) findViewById(R.id.imageView1);
Intent intent = new Intent(this, CustomCamera.class);
startActivityForResult(intent, 0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("result");
imageHolder.setImageBitmap(photo);
}
}
}
CustomCamera:
public class CustomCamera extends Activity {
private Camera mCamera;
private NewItemSurfaceView mPreview;
Button captureButton;
public static final int MEDIA_TYPE_IMAGE = 1;
public static final int MEDIA_TYPE_VIDEO = 2;
public static final String MY_CAMERRA_APP = "MyCameraApp";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.al_newitem_camera);
captureButton = (Button) findViewById(R.id.buttonClick);
// Create an instance of Camera
mCamera = getCameraInstance();
mCamera.setDisplayOrientation(90);
// Create our Preview view and set it as the content of our activity.
mPreview = new NewItemSurfaceView(this, mCamera);
FrameLayout preview = (FrameLayout) findViewById(R.id.flCamera);
preview.addView(mPreview);
// Add a listener to the Capture button
captureButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// get an image from the camera
mCamera.takePicture(null, null, mPicture);
}
});
}
/** A safe way to get an instance of the Camera object. */
public static Camera getCameraInstance() {
Camera c = null;
try {
c = Camera.open(); // attempt to get a Camera instance
} catch (Exception e) {
// Camera is not available (in use or does not exist)
}
return c; // returns null if camera is unavailable
}
private PictureCallback mPicture = new PictureCallback() {
#Override
public void onPictureTaken(byte[] data, Camera camera) {
File pictureFile = getOutputMediaFile(MEDIA_TYPE_IMAGE);
if (pictureFile == null) {
Log.d("Camera error",
"Error creating media file, check storage permissions: ");
return;
}
Log.i("Picture", pictureFile.toString());
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
fos.close();
} catch (FileNotFoundException e) {
Log.d("Camera error", "File not found: " + e.getMessage());
} catch (IOException e) {
Log.d("Camera error", "Error accessing file: " + e.getMessage());
}
Intent returnIntent = new Intent();
returnIntent.putExtra("result", pictureFile);
setResult(RESULT_OK, returnIntent);
finish();
}
};
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type) {
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM),
"MyCameraApp");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.i("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "IMG_" + timeStamp + ".jpg");
} else if (type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "VID_" + timeStamp + ".mp4");
} else {
return null;
}
return mediaFile;
}
}
modify onActivityResult method like this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK) {
String photoPath = (String) data.getExtras().get("result");
imageHolder.setImageBitmap(BitmapFactory.decodeFile("photoPath"));
}
}
Do some modification in your onPictureTaken method like this
Intent returnIntent = getIntent();
returnIntent.putExtra("result", pictureFile.getAbsolutePath());
setResult(RESULT_OK, returnIntent);
finish();

Android: Take Picture, then immediately do crop w/o needing to select from gallery

I have complete working code to take a picture, crop it, send email with image attachment.
Here is the flow of the code:
Take a picture > Find and select the picture we just took from Gallery > Crop it > Email attachment.
I would like to find out how I can skip the whole "Find and select the picture we just took from Gallery" part out and just go straight into cropping immediately after taking the picture.
Is there an Intent that can do what I am requesting?
I've tried this tutorial but it still makes the user go into gallery and look for the picture they just took

EDIT I should also mention that I have a custom view when I am taking pictures so Im not sure if I can use Intent MediaStore.ACTION_IMAGE_CAPTURE
Here is the code that executes the cropping AND also makes you choose the image you just took by looking in the gallery.
Intent crop_pic = new Intent(Intent.ACTION_PICK, uriTarget); // used to be ACTION_GET_CONTENT /ACTION_PICK
crop_pic.putExtra("crop", "true"); // this enables crop feature
//crop_pic.putExtra("aspectX", 200); // this defines the aspect ration
//crop_pic.putExtra("aspectY", 150);
//crop_pic.putExtra("outputX", 500); // this defines the output bitmap size
//crop_pic.putExtra("outputY", 500);
//crop_pic.putExtra("scale", true);
try { crop_pic.putExtra("return-data", false); // true to return a Bitmap, false to directly save the cropped iamge
crop_pic.putExtra(MediaStore.EXTRA_OUTPUT, uriTarget); // save output image in uri
//crop_pic.setDataAndType(uriTarget, "image/*"); // this will open all images in the Galery
startActivityForResult(crop_pic, EMAIL_PIC);
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
}
catch (ActivityNotFoundException e) {
toast.showToastDialog(getApplicationContext(), e.toString());
}
LOGCAT.DEBUG(TAG, "Cropping Picture");
}
Is there an Intent im not aware of that can just start cropping if I supply it with a uri Target?
Here is the full code:

You just need to use the MediaStore.ACTION_IMAGE_CAPTURE intent action. That will launch the camera. And in your onActivityResult you can get a the image that was just taken. Now you can crop it and send it and whatever else you'd like. Below is an example.
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File pics = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File cameraPhotoFile = new File(pics, System.currentTimeMillis()+".jpg");
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(cameraPhotoFile));
startActivityForResult(cameraIntent, REQUEST_CODE_CAMERA);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != Activity.RESULT_OK) return;
if (requestCode == REQUEST_CODE_CAMERA) {
MediaScannerConnection.scanFile(this,
new String[]{cameraPhotoFile.getAbsolutePath()}, null, null);
// do something with the image located at cameraPhotoFile
I've included the MediaScannerConnection because the image will not show up in the gallery until it gets scanned. You can remove that if you want, but I like images that were taken to show up. The bitmap is now located in the "cameraPhotoFile." Use that file however you like.
Also, here are the docs from Google about this called Taking Photos Simply. It's pretty straight forward
The easiest solution i can think of is:
Call the ACTION_IMAGE_CAPTURE Intent to take a picture with the Stock Camera
onActivityResult you will get the content uri of the new picture over data.getData()
Do it like vogella here http://blog.vogella.com/2011/09/13/android-how-to-get-an-image-via-an-intent/ and directly open an inputstream to the new picture
no need for the pick intent.
