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);
USER ABOVE LINE OF CODE AND FOLLOW BELOW LINK

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();
}
}

issue regarding converting image to Base64 image

This is Image feathing method
private void selectImage() {
final CharSequence[] options = {"Take Photo", "Choose from Gallery", "Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(AddServiceActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 100);
} else if (options[item].equals("Choose from Gallery")) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 10);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
This is OnActivityResult code
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (data.getData() != null) {
selectedImageUri = data.getData();
} else {
Log.d("selectedPath1 : ", "Came here its null !");
Toast.makeText(getApplicationContext(), "failed to get Image!", Toast.LENGTH_SHORT).show();
}
if (requestCode == 100 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
selectedPath = getPath(selectedImageUri);
camera.setImageURI(selectedImageUri);
Log.d("selectedPath1 : ", selectedPath);
getimage(selectedImageUri);
}
if (requestCode == 10)
{
Uri selectedImage = data.getData();
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor c = getContentResolver().query(selectedImage, filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
Log.w("path of image from ", picturePath + "");
camera.setImageBitmap(thumbnail);
getimage(selectedImage);
}
}
}
Image changing code id here
private void getimage(final Uri uri) {
Bitmap image = null;
WeakReference<Bitmap> weakReference = new WeakReference<Bitmap>(new BitmapDrawable(getResources(), uri.getPath()).getBitmap());
int nh = (int) (weakReference.get().getHeight() * (512.0 / weakReference.get().getWidth()));
image = Bitmap.createScaledBitmap(weakReference.get(), 512, nh, true);
Log.e("", "bitmap size is2:" + "" + nh + ":" + image.getByteCount());
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
Log.e("", "encoded::" + encoded);
Log.d("", "encoded::" + encoded);
// user_imagebase64 = encoded;
try {
byteArrayOutputStream.flush();
byteArrayOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
the code is crashes in getimage method all time, when i call this method the app crashes at line
"int nh = (int) (weakReference.get().getHeight() * (512.0 / weakReference.get().getWidth()));"
and having error of Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getHeight()' on a null object reference
i dont know what the issue is and i can't use this code too..

Camera Activity not returns path of image

I have task to capture image from camera and send that image to crop Intent. following is the code i have written
for camera capture
Intent captureIntent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(captureIntent, CAMERA_CAPTURE);
In on Activity result
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_CAPTURE) {
// get the Uri for the captured image
picUri = data.getData(); // picUri is global string variable
performCrop();
}
}
}
public void performCrop() {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(picUri, "image/*");
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", 3);
cropIntent.putExtra("aspectY", 2);
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
cropIntent.putExtra("return-data", true);
startActivityForResult(cropIntent, CROP_PIC);
} catch (ActivityNotFoundException anfe) {
String errorMessage = "Your device doesn't support the crop action";
Toast toast = Toast.makeText(getApplicationContext(), errorMessage,
Toast.LENGTH_SHORT);
toast.show();
}
}
I am getting different behaviours on different devices
In some devices i am getting error "couldn't find item".
In some devices after capturing image activity stuck and doesn't go ahead
I have also tried this
Please tell me the Right way to do this

You can by calling the intent like below:
int REQUEST_IMAGE_CAPTURE = 1;
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
((Activity) context).startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
And in your activity inside OnActivityResult you get the path like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_IMAGE_CAPTURE) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
Bitmap bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
Matrix matrix = new Matrix();
matrix.postRotate(-90);
Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
rotatedBitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
byte[] attachmentBytes = byteArrayOutputStream.toByteArray();
String attachmentData = Base64.encodeToString(attachmentBytes, Base64.DEFAULT);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "CTSTemp" + File.separator + "default";
f.delete();
ESLogging.debug("Bytes size = " + attachmentBytes.length);
ESLogging.debug("FilePath = " + path);
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
} catch (FileNotFoundException e) {
ESLogging.error("FileNotFoundException while uploading new attachment in class HomeActivity", e);
e.printStackTrace();
} catch (IOException e) {
ESLogging.error("IOException while uploading new attachment in class HomeActivity", e);
e.printStackTrace();
} catch (Exception e) {
ESLogging.error("Exception while uploading new attachment in class HomeActivity", e);
e.printStackTrace();
}
} catch (Exception e) {
ESLogging.error("Exception while uploading new attachment in class HomeActivity", e);
e.printStackTrace();
}
}
}
}

//Declare this in class
private static int RESULT_LOAD_IMAGE = 1;
String picturePath="";
// write in button click event
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
//copy this code in after onCreate()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.img); //place imageview in your xml file
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
write the following permission in manifest file
1.read external storage
2.write external storage

Android "TAKE PHOTO" - Image which is clicked is getting saved as a corrupt image

I have a button, which opens up a dialog box asking user to either "Take Picture" or "Choose from gallery".
I am facing issues when user "Take photo" , image is getting clicked, and for verification purpose I am setting Bitmap image inside the circularImage view, but when I go to specified location path of the image, either Image is not there or Image is corrupted.
Also I am trying to upload the image to the server using AsyncHttpClient in android but not being able to do it successfully.
Everytime I am getting Java Socket TimeOut Exception.

I simplified your code .keep reference of file path global
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");
globalpath =f.getAbsolutePath(); //String make it global
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
//your onactivityresult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File myfile = new File(globalpath);
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(myfile.getAbsolutePath(),
bitmapOptions);
ProfilePictureImage.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Pictures" + File.separator + "Screenshots";
OutputStream outFile;
File file = new File(path, String.valueOf(System
.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
myfile.delete();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

Depending on your Android version and device, the camera intent is to be implemented differently. Check out https://github.com/ralfgehrer/AndroidCameraUtil. The code is tested on 100+ devices.

After take the photo remember to use this:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
to scan the media file in your gallery. If you doesn't do it your photo will appear after some time. You can do it in onClick:
insertImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
selectImage();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
}
});

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);
}
