How to capture an image?

How to capture an image? - android

I have problem about capturing image on Android via camera. I show my source of my Android app below.
public class RegisterActivity extends AppCompatActivity {
private Kelolajson json;
private Button btnfoto;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
......
json = new KelolaJson();
btnfoto = (Button) findViewById(R.id.fotobtn);
btnfoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (isDeviceSupportCamera()) {
f_foto =txthp.getText().toString() +".jpg";
fname= txthp.getText().toString();
captureImage();
}
else {
Toast.makeText(getApplicationContext(),"Your Mobile don't support camera",Toast.LENGTH_LONG).show();
}
}
});
......
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// successfully captured the image display it in image view
String root = Environment.getExternalStorageDirectory().toString();
String path = root + "/Pictures/myapp";
gmbpath = fileUri.getPath().toString();
Bitmap tmp = BitmapFactory.decodeFile(gmbpath);
imgpreview.setImageBitmap(tmp);
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(getApplicationContext(),
"You has been canceled capture.",
Toast.LENGTH_SHORT).show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry, Can\'t get photo",
Toast.LENGTH_SHORT).show();
}
}
}
public Uri getOutputMediaFileUri(int type) {
return Uri.fromFile(getOutputMediaFile(type));
}
private static File getOutputMediaFile(int type) {
//External sdcard location
File mediaStorageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
"myapp");
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
File mediaFile = null;
if (type == MEDIA_TYPE_IMAGE) {
fname = "_" + timeStamp;
f_foto = tmp_hp + ".jpg";
mediaFile = new File(mediaStorageDir.getPath() + File.separator + f_foto);
} else {
mediaFile= null;
}
return mediaFile;
}
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
}
This source code has been running well on mobile Smartphone. But some smartphone's result of captured photo always changed orientation. For example, I capture image by smartphone portrait orientation but result of smartphone capture image is landscape orientation. Also, if landscape orientation, it is result changed to portrait orientation. This result don't follow smartphone orientation.

Checks for orientation associated with URI of the captured image from the camera.
try {
getContentResolver().notifyChange(imageUri, null);
File imageFile = new File(imagePath);
ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
}
Log.v(Common.TAG, "Exif orientation: " + orientation);
} catch (Exception e) {
e.printStackTrace();
}
Matrix matrix = new Matrix();
matrix.postRotate(orientation);
Bitmap cropped = Bitmap.createBitmap(scaled, x, y, width, height, matrix, true);
Apparently Samsung phones set the EXIF orientation tag, rather than rotating individual pixels.Reading the Bitmap using BitmapFactory does not support this tag.What i found the solution to this problem was using ExifInterface in onActivityResult method of the activity.

Try this code:
private static final int CAMERA_PIC_REQUEST = 1337;
Button btnn;
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnn = (Button) findViewById(R.id.btn);
imageView = (ImageView) findViewById(R.id.Img);
sf = getSharedPreferences("photo", Context.MODE_PRIVATE);
String de = sf.getString("image", "");
byte[] c = Base64.decode(de, Base64.DEFAULT);
Bitmap bb = BitmapFactory.decodeByteArray(c, 0, c.length);
imageView.setImageBitmap(bb);
btnn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PIC_REQUEST);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK && null != data) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
byte[] b = bytes.toByteArray();
String img = Base64.encodeToString(b, Base64.DEFAULT);
SharedPreferences.Editor editor = sf.edit();
editor.putString("image", img);
editor.commit();
imageView.setImageBitmap(thumbnail);
}
}

Save image in original form and without compressing

I want to save the image without compressing it and want to save it in it's original form i.e. when image is compressed the image size decreases and image become small. I am using native camera for this purpose. I am working in android studio. I am making an app in which i am using a camera to save image. But the image is compressed and is very small and very lower quality.
Below is my code for saving image
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE)
{
if(resultCode == Activity.RESULT_OK)
{
Bitmap bmp = (Bitmap)data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();
// convert byte array to Bitmap
Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
if(isStoragePermissionGranted())
{
SaveImage(bitmap);
}
}
}else {
switch (requestCode) {
case 1000:
switch (resultCode) {
case Activity.RESULT_OK:
// All required changes were successfully made
getLocation();
break;
case Activity.RESULT_CANCELED:
// The user was asked to change settings, but chose not to
Toast.makeText(this, "Location Service not Enabled", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
break;
}
}
}
private void SaveImage(Bitmap finalBitmap) {
File storageDir = new File (String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)));
String root = storageDir + Environment.getExternalStorageDirectory().getAbsolutePath().toString();
Log.v(LOG_TAG, root);
File myDir = new File(root + "/captured_images");
if (!myDir .exists())
{
myDir .mkdirs();
}
Random generator = new Random();
int n = 1000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir,fname);
try {
file.createNewFile();
MediaScannerConnection.scanFile(getApplicationContext(), new String[] {file.getPath()} , new String[]{"image/*"}, null);
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG,100,out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Update 1
For more understanding i am putting my onClick method
btn_camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Check permission for camera
if(ActivityCompat.checkSelfPermission(MainActivity.this, CAMERA)
!= PackageManager.PERMISSION_GRANTED)
{
// Check Permissions Now
// Callback onRequestPermissionsResult interceptado na Activity MainActivity
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{CAMERA},
MainActivity.REQUEST_CAMERA);
}
else {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE );
}
}
});
I searched the solution and found that i can use AndroidBitmapUtil
class so i copy and pasted this class into my project i.e. i created a new class. But i don't know how to use it. Although it is described that i can save image by doing new AndroidBmpUtil().save(bmImage, file);. But again i can't match with my code :(
Any help would be highly appreciated

new AndroidBmpUtil().save(source, sdcardBmpPath);

Open Camera and save image into some specific directory.
solution number 1
private String pictureImagePath = "";
private void openBackCamera() {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = timeStamp + ".jpg";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
pictureImagePath = storageDir.getAbsolutePath() + "/" + imageFileName;
File file = new File(pictureImagePath);
Uri outputFileUri = Uri.fromFile(file);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, 1);}
Handle Image
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
File imgFile = new File(pictureImagePath);
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
myImage.setImageBitmap(myBitmap);
}
}
solution number 2
I have used the following code and this works perfectly fine for me.
values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, PICTURE_RESULT);
and also
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICTURE_RESULT:
if (requestCode == PICTURE_RESULT)
if (resultCode == Activity.RESULT_OK) {
try {
thumbnail = MediaStore.Images.Media.getBitmap(
getContentResolver(), imageUri);
imgView.setImageBitmap(thumbnail);
imageurl = getRealPathFromURI(imageUri);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
and
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

For opening camera use
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "imagename.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
and in your onActivityresult method use
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("imagename.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),bitmapOptions);
yourimageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}

Also it takes too much time to select or capture the image more than 10 seconds, what can be the reason?
Can anyone help please? Thank you..

Android onclick radio button camera intent not working

i have a radio button. when i click on radio button camera intent is opened after taking a image using camera. image is not updating to image view.
i have used all permissions in my manifest file.
RB_PhotoStatus
.setOnCheckedChangeListener(new android.widget.RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group,
int checkedId) {
switch (checkedId) {
case R.id.yes:
//photoCollected = "Yes";
// create intent with ACTION_IMAGE_CAPTURE action
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
break;
case R.id.no:
photoCollected = "No";
break;
}
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap bp = (Bitmap) data.getExtras().get("data");
imageView1.setImageBitmap(bp);
}

Taking Photos Simply!
This answer explains how to capture photos using an existing camera application.
<manifest ... >
<uses-feature android:name="android.hardware.camera"
android:required="true" />
...
</manifest>
Request for camera application.
static final int REQUEST_IMAGE_CAPTURE = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
Camera return intent with data on Activity override function onActivityResult as bellow:-
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
}
}
For more info follows this link given bellow:
http://developer.android.com/training/camera/photobasics.html

It doesn't work because Camera Intent won't return the entire BitMap, but only the reference (Uri) to the created file.
Uri selectedImage = data.getData();
From this Uri you may re-load the BitMap using BitmapFactory.decodeFile

On radiobuttonclick();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
onActivityResult();
Uri originalUri = data.getData();
imageview.setImageURI(originalUri);
And If you want to get bitmap then
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), originalUri);

private String mCurrentPhotoPath;
final String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
final File image = create_directory();
// Save a file: path for use with ACTION_VIEW intents
try {
mCurrentPhotoPath = image.getAbsolutePath();
} catch (Exception e) {
e.printStackTrace();
}
final Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
if (image != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(image));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
} else {
snackbar = Snackbar.make(findViewById(android.R.id.content), "An error has occurred", Snackbar.LENGTH_SHORT);
snackbar.setAction("Dismiss", clickListener);
snackbar.show();
}
}
}
public File create_directory() {
// Create an image file name
final String imageFileName;
final String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.ENGLISH).format(new Date());
final String user_id = "1_";
imageFileName = user_id + timeStamp + "_";
final String proj_name = "test";
final String folder_timeStamp = new SimpleDateFormat("yyyyMMdd", Locale.ENGLISH).format(new Date());
final String path = "/TEST/" + proj_name + "/" + folder_timeStamp;
final File dr = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), path);
if (!dr.exists()) {
dr.mkdirs();
}
File image = null;
try {
image = File.createTempFile(imageFileName, ".jpg", dr);
} catch (IOException e) {
e.printStackTrace();
}
return image;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE) {
if (resultCode == RESULT_OK){
//do something with the image which is stored in mCurrentPhotoPath
}
}
}

Take photo w/ camera intent and display in imageView or textView?

I have a question about how to take an image using the camera intent (or camera API) and then bring the image into an imageView for me to display in my application. This is what I have so far.
I setup a button
Button btnPicture = (Button) findViewById(R.id.btn_picture);
btnPicture.setOnClickListener(this);
I setup a Camera method
private void Camera() {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PICTURE_CODE);
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(intent, REQUEST_CODE);
}
And this is where I am lost. I am trying to process the image that I took.
private void processImage(Intent intent) {
setContentView(R.layout.imagelayout);
ImageView imageView = (ImageView)findViewById(R.id.image_view);
cameraBitmap = (Bitmap)intent.getExtras().get("data");
imageView.setImageBitmap(cameraBitmap);
}
My intent is to display the image that you took inside image_view. I am not receiving an error, nothing happens. When I take the picture, I am asked to either take another picture or after I use the device back button the application force closes. It seems that I am taken out of my application completely, and returning is a big issue. Any suggestions? What am I missing?
O yea, and here is my onActivityResult
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(TAKE_PICTURE_CODE == requestCode) {
Bundle extras = data.getExtras();
if (extras.containsKey("data")) {
Bitmap bmp = (Bitmap) extras.get("data");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] image = baos.toByteArray();
if (image != null) {
Log.d(TAG, "image != null");
}
} else {
Toast.makeText(getBaseContext(), "Fail to capture image", Toast.LENGTH_LONG).show();
}
}
}
I am trying to put the image in getExtras, and then store it to a ByteArray. Was another thing I was trying to do. Not sure how it all comes together.

The method which i found to be easy and helpful is this:
MainActivity
private static String root = null;
private static String imageFolderPath = null;
private String imageName = null;
private static Uri fileUri = null;
private static final int CAMERA_IMAGE_REQUEST=1;
public void captureImage(View view) {
ImageView imageView = (ImageView) findViewById(R.id.capturedImageview);
// fetching the root directory
root = Environment.getExternalStorageDirectory().toString()
+ "/Your_Folder";
// Creating folders for Image
imageFolderPath = root + "/saved_images";
File imagesFolder = new File(imageFolderPath);
imagesFolder.mkdirs();
// Generating file name
imageName = "test.png";
// Creating image here
File image = new File(imageFolderPath, imageName);
fileUri = Uri.fromFile(image);
imageView.setTag(imageFolderPath + File.separator + imageName);
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePictureIntent,
CAMERA_IMAGE_REQUEST);
}
and then in your activity onActivityResult method:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case CAMERA_IMAGE_REQUEST:
Bitmap bitmap = null;
try {
GetImageThumbnail getImageThumbnail = new GetImageThumbnail();
bitmap = getImageThumbnail.getThumbnail(fileUri, this);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// Setting image image icon on the imageview
ImageView imageView = (ImageView) this
.findViewById(R.id.capturedImageview);
imageView.setImageBitmap(bitmap);
break;
default:
Toast.makeText(this, "Something went wrong...",
Toast.LENGTH_SHORT).show();
break;
}
}
}
GetImageThumbnail.java
public class GetImageThumbnail {
private static int getPowerOfTwoForSampleRatio(double ratio) {
int k = Integer.highestOneBit((int) Math.floor(ratio));
if (k == 0)
return 1;
else
return k;
}
public Bitmap getThumbnail(Uri uri, Context context)
throws FileNotFoundException, IOException {
InputStream input = context.getContentResolver().openInputStream(uri);
BitmapFactory.Options onlyBoundsOptions = new BitmapFactory.Options();
onlyBoundsOptions.inJustDecodeBounds = true;
onlyBoundsOptions.inDither = true;// optional
onlyBoundsOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;// optional
BitmapFactory.decodeStream(input, null, onlyBoundsOptions);
input.close();
if ((onlyBoundsOptions.outWidth == -1)
|| (onlyBoundsOptions.outHeight == -1))
return null;
int originalSize = (onlyBoundsOptions.outHeight > onlyBoundsOptions.outWidth) ? onlyBoundsOptions.outHeight
: onlyBoundsOptions.outWidth;
double ratio = (originalSize > 400) ? (originalSize / 350) : 1.0;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmapOptions.inSampleSize = getPowerOfTwoForSampleRatio(ratio);
bitmapOptions.inDither = true;// optional
bitmapOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;// optional
input = context.getContentResolver().openInputStream(uri);
Bitmap bitmap = BitmapFactory.decodeStream(input, null, bitmapOptions);
input.close();
return bitmap;
}
}
and then on the ImageView onclick method will be like this:
public void showFullImage(View view) {
String path = (String) view.getTag();
if (path != null) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri imgUri = Uri.parse("file://" + path);
intent.setDataAndType(imgUri, "image/*");
startActivity(intent);
}
}

To take photo correctly you should store it in temp file, because data in result intent can be null:
final Intent pickIntent = new Intent();
pickIntent.setType("image/*");
pickIntent.setAction(Intent.ACTION_GET_CONTENT);
final String pickTitle = activity.getString(R.string.choose_image);
final Intent chooserIntent = Intent.createChooser(pickIntent, pickTitle);
if (AvailabilityUtils.isExternalStorageReady()) {
final Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
final Uri fileUri = getCameraTempFileUri(activity, true);
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
new Intent[] { takePhotoIntent });
}
activity.startActivityForResult(chooserIntent, REQUEST_CODE);
And then get photo from Uri:
if (requestCode == ProfileDataView.REQUEST_CODE
&& resultCode == Activity.RESULT_OK) {
final Uri dataUri = data == null ? getCameraTempFileUri(context,
false) : data.getData();
final ParcelFileDescriptor pfd = context.getContentResolver()
.openFileDescriptor(imageUri, "r");
final FileDescriptor fd = pfd.getFileDescriptor();
final Bitmap bitmap = BitmapFactory.decodeFileDescriptor(fd);

I am building an application where I want to capture an image by the default camera activity and return back to my activity and load that image in a ImageView. The problem is camera activity always returning null. In my onActivityResult(int requestCode, int resultCode, Intent data) method I am getting data as null. Here is my code:
public class CameraCapture extends Activity {
protected boolean _taken = true;
File sdImageMainDirectory;
Uri outputFileUri;
protected static final String PHOTO_TAKEN = "photo_taken";
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
setContentView(R.layout.cameracapturedimage);
File root = new File(Environment
.getExternalStorageDirectory()
+ File.separator + "myDir" + File.separator);
root.mkdirs();
sdImageMainDirectory = new File(root, "myPicName");
startCameraActivity();
} catch (Exception e) {
finish();
Toast.makeText(this, "Error occured. Please try again later.",
Toast.LENGTH_SHORT).show();
}
}
protected void startCameraActivity() {
outputFileUri = Uri.fromFile(sdImageMainDirectory);
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE:
{
if(resultCode==Activity.RESULT_OK)
{
try{
ImageView imageView=(ImageView)findViewById(R.id.cameraImage);
imageView.setImageBitmap((Bitmap) data.getExtras().get("data"));
}
catch (Exception e) {
// TODO: handle exception
}
}
break;
}
default:
break;
}
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
if (savedInstanceState.getBoolean(CameraCapture.PHOTO_TAKEN)) {
_taken = true;
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putBoolean(CameraCapture.PHOTO_TAKEN, _taken);
}
}
Am I doing anything wrong?

You are getting wrong because you are doing it wrong way.
If you pass the extra parameter MediaStore.EXTRA_OUTPUT with the camera intent then camera activity will write the captured image to that path and it will not return the bitmap in the onActivityResult method.
If you will check the path which you are passing then you will know that actually camera had write the captured file in that path.
For further information you can follow this, this and this

I am doing it another way. The data.getData() field is not guaranteed to return a Uri, so I am checking if it's null or not, if it is then the image is in extras. So the code would be -
if(data.getData()==null){
bitmap = (Bitmap)data.getExtras().get("data");
}else{
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), data.getData());
}
I am using this code in the production application, and it's working.

I had a similar problem. I had commented out some lines in my manifest file which caused the thumbnail data to be returned as null.
You require the following to get this to work:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
I hope this resolves your issue
If you phone is a Samsung, it could be related to this http://kevinpotgieter.wordpress.com/2011/03/30/null-intent-passed-back-on-samsung-galaxy-tab/
There is another open question which may give additional information

If you are using an ImageView to display the Bitmap returned by Camera Intent
you need to save the imageview reference inside onSaveInstanceState and also restore it later on inside onRestoreInstanceState. Check out the code for onSaveInstanceState and onRestoreInstanceState below.
public class MainActivity extends Activity {
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 1;
String mCurrentPhotoPath;
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
imageView = (ImageView) findViewById(R.id.imageView1);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.activity_main);
}
#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;
}
public void startCamera(View v) throws IOException {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photoFile = null;
photoFile = createImageFile();
//intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photoFile));
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE
&& resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
System.out.println(imageBitmap);
imageView.setImageBitmap(imageBitmap);
}
}
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
System.out.println(mCurrentPhotoPath);
return image;
}
private void setPic() {
// Get the dimensions of the View
int targetW = imageView.getWidth();
int targetH = imageView.getHeight();
// Get the dimensions of the bitmap
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);
int photoW = bmOptions.outWidth;
int photoH = bmOptions.outHeight;
// Determine how much to scale down the image
int scaleFactor = Math.min(photoW/targetW, photoH/targetH);
// Decode the image file into a Bitmap sized to fill the View
bmOptions.inJustDecodeBounds = false;
bmOptions.inSampleSize = scaleFactor;
bmOptions.inPurgeable = true;
Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);
imageView.setImageBitmap(bitmap);
}
#Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
System.out.println(mCurrentPhotoPath);
imageView = (ImageView) findViewById(R.id.imageView1);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onRestoreInstanceState(savedInstanceState);
System.out.println(mCurrentPhotoPath);
imageView = (ImageView) findViewById(R.id.imageView1);
}
}

after many search :
private static final int TAKE_PHOTO_REQUEST = 1;
private ImageView mImageView;
String mCurrentPhotoPath;
private File photoFile;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_saisir_frais);
mImageView = (ImageView) findViewById(R.id.imageViewPhoto);
dispatchTakePictureIntent();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_REQUEST && resultCode == RESULT_OK) {
// set the dimensions of the image
int targetW =100;
int targetH = 100;
// Get the dimensions of the bitmap
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inJustDecodeBounds = true;
BitmapFactory.decodeFile(photoFile.getAbsolutePath(), bmOptions);
int photoW = bmOptions.outWidth;
int photoH = bmOptions.outHeight;
// Determine how much to scale down the image
int scaleFactor = Math.min(photoW/targetW, photoH/targetH);
// Decode the image file into a Bitmap sized to fill the View
bmOptions.inJustDecodeBounds = false;
bmOptions.inSampleSize = scaleFactor;
bmOptions.inPurgeable = true;
// stream = getContentResolver().openInputStream(data.getData());
Bitmap bitmap = BitmapFactory.decodeFile(photoFile.getAbsolutePath(),bmOptions);
mImageView.setImageBitmap(bitmap);
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
private void dispatchTakePictureIntent() {
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try {
photoFile = createImageFile();
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(takePhotoIntent, TAKE_PHOTO_REQUEST);
} catch (IOException e) {
e.printStackTrace();
}
}

Try following code
{
final String[] imageColumns = { MediaStore.Images.Media._ID,MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, null, null, imageOrderBy);
imageCursor.moveToFirst();
do {
String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
if (fullPath.contains("DCIM")) {
//get bitmap from fullpath here.
return;
}
}
while (imageCursor.moveToNext());

While taking from camera few mobiles would return null. The below workaround will solve. Make sure to check data is null:
private int CAMERA_NEW = 2;
private String imgPath;
private void takePhotoFromCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri());
startActivityForResult(intent, CAMERA_NEW);
}
// to get the file path
private Uri setImageUri() {
// Store image in dcim
File file = new File(Environment.getExternalStorageDirectory() + "/DCIM/", "image" + new Date().getTime() + ".png");
Uri imgUri = Uri.fromFile(file);
this.imgPath = file.getAbsolutePath();
return imgUri;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_NEW) {
try {
Log.i("Crash","CAMERA_NEW");
if(data!=null &&(Bitmap) data.getExtras().get("data")!=null){
bitmap = (Bitmap) data.getExtras().get("data");
personImage.setImageBitmap(bitmap);
Utils.saveImage(bitmap, getActivity());
}else{
File f= new File(imgPath);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
options.inSampleSize= 4;
bitmap = BitmapFactory.decodeStream(new FileInputStream(f), null, options);
personImage.setImageBitmap(bitmap);
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getActivity(), "Failed!", Toast.LENGTH_SHORT).show();
}
}

You can generate bitmap from the file that you send to camera intent. Please use this code...
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
switch (requestCode) {
case CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE:
{
if(resultCode==Activity.RESULT_OK)
{
int orientation = getOrientationFromExif(sdImageMainDirectory);// get orientation that image taken
BitmapFactory.Options options = new BitmapFactory.Options();
InputStream is = null;
Matrix m = new Matrix();
m.postRotate(orientation);//rotate image
is = new FileInputStream(sdImageMainDirectory);
options.inSampleSize = 4 //(original_image_size/4);
Bitmap bitmap = BitmapFactory.decodeStream(is,null,options);
bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),
bitmap.getHeight(), m, true);
// set bitmap to image view
//bitmap.recycle();
}
break;
}
default:
break;
}
}
private int getOrientationFromExif(String imagePath) {
int orientation = -1;
try {
ExifInterface exif = new ExifInterface(imagePath);
int exifOrientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (exifOrientation) {
case ExifInterface.ORIENTATION_ROTATE_270:
orientation = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
orientation = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
orientation = 90;
break;
case ExifInterface.ORIENTATION_NORMAL:
orientation = 0;
break;
default:
break;
}
} catch (IOException e) {
//Log.e(LOG_TAG, "Unable to get image exif orientation", e);
}
return orientation;
}

File cameraFile = null;
public void openChooser() {
Intent pickIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraFile = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(cameraFile));
String pickTitle = "Select or take a new Picture"; // Or get from strings.xml
Intent chooserIntent = Intent.createChooser(pickIntent, pickTitle);
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,new Intent[]{takePhotoIntent});
startActivityForResult(chooserIntent, SELECT_PHOTO);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case SELECT_PHOTO:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = data.getData();
if (selectedImage != null) {
//from gallery
} else if (cameraFile != null) {
//from camera
Uri cameraPictureUri = Uri.fromFile(cameraFile);
}
}
break;
}
}

Try this tutorial. It works for me and use permission as usual in manifesto & also
check permission

After a lot of vigorous research I finally reached to a conclusion.
For doing this, you should save the image captured to the external storage.
And then,retrieve while uploading.
This way the image res doesnt degrade and you dont get NullPointerException too!
I have used timestamp to name the file so we get a unique filename everytime.
private void fileChooser2() {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Intent intent=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File pictureDirectory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
String pictureName=getPictureName();
fi=pictureName;
File imageFile=new File(pictureDirectory,pictureName);
Uri pictureUri = Uri.fromFile(imageFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT,pictureUri);
startActivityForResult(intent,PICK_IMAGE_REQUEST2);
}
Function to create a file name :
private String getPictureName() {
SimpleDateFormat adf=new SimpleDateFormat("yyyyMMdd_HHmmss");
String timestamp = adf.format(new Date());
return "The New image"+timestamp+".jpg";//give a unique string so that the imagename cant be overlapped with other apps'image formats
}
and the onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==PICK_IMAGE_REQUEST2 && resultCode==RESULT_OK )//&& data!=null && data.getData()!=null)
{
final ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.setTitle("Uploading");
progressDialog.show();
Toast.makeText(getApplicationContext(),"2",Toast.LENGTH_SHORT).show();
File picDir=Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File imageFile=new File(picDir.getAbsoluteFile(),fi);
filePath=Uri.fromFile(imageFile);
try {
}catch (Exception e)
{
e.printStackTrace();
}
StorageReference riversRef = storageReference.child(mAuth.getCurrentUser().getUid()+"/2");
riversRef.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "File Uploaded ", Toast.LENGTH_LONG).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), exception.getMessage(), Toast.LENGTH_LONG).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
progressDialog.setMessage("Uploaded " + ((int) progress) + "%...");
}
});
Edit: give permissions for camera and to write and read from storage in your manifest.
