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
}
}
}

So.. I'm trying to choose a picture using both camera and gallery, then pass it to an external library to crop image.
The problem lies with saving image after taking it with the camera. I've managed to get the camera running and take an image with it, then it display the image and the default Android Ok and back button. The Ok button responds to touch (as touch effect can be seen) but it doesn't do anything.
Here's the code for getting the file ready to save
date = calendar.getTime();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("ddMMyyyyHHmmss");
dateString = simpleDateFormat.format(date);
dateBuilder = new StringBuilder().append(dateString).append(".jpg");
SAMPLE_CROPPED_IMAGE_NAME = dateBuilder.toString();
final String cameraDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/SamplePics/";
newDir = new File(cameraDir);
newDir.mkdirs();
This is the code for camera function
RelativeLayout.OnClickListener photoCameraWrapperHandler = new RelativeLayout.OnClickListener(){
#Override
public void onClick(View v) {
//Intent intent = new Intent(SignupStepThreeActivity.this, SignupStepFourActivity.class);
//startActivity(intent);
String cameraFile = SAMPLE_CROPPED_IMAGE_NAME;
newFile = new File(cameraFile);
try {
newFile.createNewFile();
}
catch (IOException e)
{
}
Uri outputFileUri = Uri.fromFile(newFile);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
};
And here's the onActivityResult :
private static final int CAMERA_REQUEST = 1888;
private static final int REQUEST_SELECT_PICTURE = 0x01;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_SELECT_PICTURE || requestCode == CAMERA_REQUEST) {
final Uri selectedUri = data.getData();
if (selectedUri != null) {
startCropActivity(data.getData());
} else {
Toast.makeText(SignupStepThreeActivity.this, R.string.toast_cannot_retrieve_selected_image, Toast.LENGTH_SHORT).show();
}
} else if (requestCode == UCrop.REQUEST_CROP) {
handleCropResult(data);
}
}
if (resultCode == UCrop.RESULT_ERROR) {
handleCropError(data);
}
}
Several updates before, it crashes when I click on camera button, I suspected it was because of I kind of take the uri of the image from storage but I haven't created the folder. Now I finally managed to get the camera running but not saving. The create folder part works tho..
public String getCamerPath(Context context) {
SharedPreferences prefs = context.getSharedPreferences("setCamerPath", 0);
String value = prefs.getString("getCamerPath", "");
return value;
}
public void setCamerPath(Context context, String value)
{
SharedPreferences prefs = context.getSharedPreferences("setCamerPath", 0);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("getCamerPath", value);
editor.commit();
}
Uri outputFileUri = Uri.fromFile(newFile);
setCamerPath(this, outputFileUri.getPath());
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_SELECT_PICTURE || requestCode == CAMERA_REQUEST) {
startCropActivity(getCamerPath(this));
} else if (requestCode == UCrop.REQUEST_CROP) {
handleCropResult(data);
}
}
if (resultCode == UCrop.RESULT_ERROR) {
handleCropError(data);
}
}
In the camera OnClickListener, I commented some stuffs like this :
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//Uri outputFileUri = Uri.fromFile(newFile);
//cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
//setCamerPath(SignupStepThreeActivity.this, outputFileUri.getPath());
startActivityForResult(cameraIntent, CAMERA_REQUEST);
In my onActivityResult, I've modified a part of CAMERA_REQUEST :
else if (requestCode == CAMERA_REQUEST) {
Uri capturedImageUri = data.getData();
Bitmap bitmap;
if (capturedImageUri != null) {
startCropActivity(capturedImageUri);
} else {
Toast.makeText(SignupStepThreeActivity.this, R.string.toast_cannot_retrieve_selected_image, Toast.LENGTH_SHORT).show();
Bundle extras = data.getExtras();
bitmap = (Bitmap) extras.get("data");
Uri imageUri = getImageUri(SignupStepThreeActivity.this, bitmap);
startCropActivity(imageUri);
}
}
So basically as I've been reading around for the past 4 hours, data is Intent. It will always be not null BUT will not always contain Uri itself for the image. Because I need the Uri for a library I'm using, I use a method called getImageUri from another Stackoverflow answer.
public static Uri getImageUri(Context inContext, Bitmap inImage)
{
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
Now the problem lies with bitmap image quality after taking the image, I'm going to tinker around with it and be back with an update.
This can also resolve the problem
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
Log.d("camera", "onSaveInstance");
// save file url in bundle as it will be null on screen orientation
// changes
outState.putParcelable("file_uri", fileUri);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
Log.d("camera", "onRestoreInstance");
// get the file url
fileUri = savedInstanceState.getParcelable("file_uri");
}
I need to take a picture with the camera, save the picture, show in ImageView and when I click the Imageview show in fullscreen mode .
In the future will need to send the picture to the internet.
This is what I've done :
public void captureImage(View v) {
Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera_intent, CAMERA_PIC_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
imgView = (ImageView) findViewById(R.id.formRegister_picture);
imgView.setScaleType(ImageView.ScaleType.CENTER_CROP);
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case CAMERA_PIC_REQUEST:
if(resultCode==RESULT_OK){
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
imgView.setImageBitmap(thumbnail);
}
}
}
You can invoke camera Activity by adding these lines in your code :
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
private static int RESULT_IMAGE_CLICK = 1;
cameraImageUri = getOutputMediaFileUri(1);
// set the image file name
intent.putExtra(MediaStore.EXTRA_OUTPUT, cameraImageUri);
startActivityForResult(intent, RESULT_IMAGE_CLICK);
Now create file Uri because in some android phones you will get null data in return
so here is the method to get the image URI :
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(int type) {
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type) {
// Check that the SDCard is mounted
File mediaStorageDir = new File(
Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES);
// Create the storage directory(MyCameraVideo) if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.e("Item Attachment",
"Failed to create directory MyCameraVideo.");
return null;
}
}
java.util.Date date = new java.util.Date();
String timeStamp = getTimeStamp();
File mediaFile;
if (type == 1) {
// For unique video file name appending current timeStamp with file
// name
mediaFile = new File(mediaStorageDir.getPath() + File.separator +abc+ ".jpg");
} else {
return null;
}
return mediaFile;
}
For retrieving clicked image :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == RESULT_IMAGE_CLICK) {
// Here you have the ImagePath which you can set to you image view
Log.e("Image Name", cameraImageUri.getPath());
Bitmap myBitmap = BitmapFactory.decodeFile(cameraImageUri.getPath());
yourImageView.setImageBitmap(myBitmap);
// For further image Upload i suppose your method for image upload is UploadImage
File imageFile = new File(cameraImageUri.getPath());
uploadImage(imageFile);
}
}
}
Since there is no proper solution for this, I will put here what I have put together that is working and correct.
ImageButton takepic = (ImageButton) returnView.findViewById(R.id.takepic);
takepic.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { Intent intent = new Intent();
addPhoto();
}
});

}}
Try this, to save image to file explorer:
public void captureImage(View v) {
Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(Environment.getExternalStorageDirectory(), "image.png");
camera_intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(camera_intent, CAMERA_PIC_REQUEST);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode== Activity.RESULT_OK){
f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("image.png")) {
f = temp;
imagePath= f.getAbsolutePath();
Bitmap thumbnail= BitmapFactory.decodeFile(f.getAbsolutePath(), options);
imgView.setImageBitmap(thumbnail);
}
You can fetch image from path "imagePath" whenever you have to display it.
hello Friends....
I am currently trying to make a Dialog using Implicit Intent where i want to show my Dialog like whatsApp(Profile Photo Screen) and in this screen whatsApp are using extra field named as "Remove Photo". When i try to make same type of screen Dialog then i am unable to add this extra field("Remove Photo"). i have done all code. its working fine for three option in Dialog like(Gallery,Photo,Camera) and i am unable to handle these all in onActivityResult() . I am sending my all source code i have tried much hard , but i am not able to find the solution to do so. plz..... friends help me out from this.
In this code i am simply create a method named as openFileChooser() in which i have write all the code for creating Dialog Screen and handle this outcomes in onActivityResult()
Here Is my code
ProfilePhotoActivity.java
public class ProfilePhotoActivity extends Activity implements OnClickListener{
ImageButton back, editPhoto, selectAction;
ImageView imgCamera;
private static final int FILECHOOSER_RESULTCODE = 2888;
protected static final int CAMERA_REQUEST = 0;
protected static final int GALLERY_PICTURE = 1;
private Uri mCapturedImageURI = null;
Intent intent;
#Override

editPhoto=(ImageButton)findViewById(R.id.ibEditPhoto);
selectAction=(ImageButton)findViewById(R.id.ibSelectAction);
imgCamera=(ImageView)findViewById(R.id.imvProfilePhoto);
editPhoto.setOnClickListener(this);
selectAction.setOnClickListener(this);
back.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_back:
ProfilePhotoActivity.this.finish();
break;
case R.id.ibEditPhoto:
openFileChooser(null, null);
// startDialog();
break;
case R.id.ibSelectAction:
break;
}
}

try{
// Create AndroidExampleFolder at sdcard

if (!imageStorageDir.exists()) {
// Create AndroidExampleFolder at sdcard
imageStorageDir.mkdirs();
}
// Create camera captured image file path and name
File file = new File(
imageStorageDir + File.separator + "IMG_"
+ String.valueOf(System.currentTimeMillis())
+ ".jpg");
mCapturedImageURI = Uri.fromFile(file);
// Camera capture image intent
final Intent captureIntent = new Intent(

}
catch(Exception e){
Toast.makeText(getBaseContext(), "Exception:"+e,
Toast.LENGTH_LONG).show();
}
}
protected void onActivityResult(int requestCode, int resultCode,Intent intent) {
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (requestCode == GALLERY_PICTURE)
{
if (resultCode == RESULT_OK)
{
if (intent != null)
{
// our BitmapDrawable for the thumbnail
BitmapDrawable bmpDrawable = null;
// try to retrieve the image using the data from the intent
Cursor cursor = getContentResolver().query(intent.getData(), null, null, null, null);
if (cursor != null)
{
cursor.moveToFirst();
int idx = cursor.getColumnIndex(ImageColumns.DATA);
String fileSrc = cursor.getString(idx);
Bitmap galleryBitmap = BitmapFactory.decodeFile(fileSrc); // load preview image
galleryBitmap = Bitmap.createScaledBitmap(galleryBitmap, 200, 200, true);
String filePath = Environment.getExternalStorageDirectory()
.getAbsolutePath()+"/TimeChat/image/"+System.currentTimeMillis()+".jpg";
//imgCamera.setRotation(0);
imgCamera.setImageBitmap(galleryBitmap);
// writeToFile(filePath, galleryBitmap);
}
else
{
bmpDrawable = new BitmapDrawable(getResources(), intent.getData().getPath());
imgCamera.setImageDrawable(bmpDrawable);
}
}
else
{
Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
}
}
else if (resultCode == RESULT_CANCELED)
{
Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
}
}
else if (requestCode == CAMERA_REQUEST)
{
if (resultCode == RESULT_OK)
{
if (intent.hasExtra("data"))
{
// retrieve the bitmap from the intent
Bitmap cameraBitmap = (Bitmap) intent.getExtras().get("data");
String filePath = Environment.getExternalStorageDirectory()
.getAbsolutePath()+"/TimeChat/image/"+System.currentTimeMillis()+".jpg";
// update the image view with the bitmap
imgCamera.setImageBitmap(cameraBitmap);
// writeToFile(filePath, circleBitmap);
}
else if (intent.getExtras() == null) {
Toast.makeText(getApplicationContext(), "No extras to retrieve!", Toast.LENGTH_SHORT).show();
BitmapDrawable thumbnail = new BitmapDrawable(getResources(), intent.getData().getPath());
// update the image view with the newly created drawable
imgCamera.setImageDrawable(thumbnail);
}
}
else if (resultCode == RESULT_CANCELED) {
Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show();
}
}
}
}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
ProfilePhotoActivity.this.finish();
}
}
This looks like it will be a problem:
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (requestCode == GALLERY_PICTURE)
unless FILECHOOSER_RESULTCODE and GALLERY_PICTURE are the same ints then statement will never pass.
It may be possible to use request code to distinguish between "types" of photos i.e.
protected static final int MY_FACE_PHOTO = 0;
protected static final int MY_CAR_PHOTO = 1;
protected static final int MY_HOUSE_PHOTO = 2;
And you may use Intent.putExtra(String name, String value) when you create Intents before starting new activity, like:
#NonNls protected static final String STRING_EXTRA = "string_extra";
#NonNls protected static final String CAMERA = "camera";
#NonNls protected static final String GALLERY = "gallery";
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI
cameraIntent.putExtra(STRING_EXTRA, CAMERA);
galleryIntent.putExtra(STRING_EXTRA, GALLERY)
startActivityForResult(takePicture,
MY_FACE_PHOTO /* put here your desired request code */)
After that in onActivityResult() method you may use them:
protected void onActivityResult (int requestCode, int resultCode, Intent intent)
{
super.onActivityResult(requestCode, resultCode, intent);
if(intent != null)
{
if(resultCode == Activity.RESULT_OK)
{
String extraString = intent.getStringExtra(STRING_EXTRA);
if(extraString.equals(CAMERA))
{
// ... i. e.
switch (requestCode)
{
case MY_FACE_PHOTO:
{
// ...
break;
}
case MY_CAR_PHOTO:
{
// ...
break;
}
case MY_HOUSE_PHOTO:
{
// ...
break;
}
default:
{
// ...
break;
}
}
}
else if(extraString.equals(GALLERY))
{
// ...
}
}
else
{
// ...
}
}
}
This code worked on samsung before but now that i'm using Nexus One with Android 2.3.6, it's crashing as soon as I take a picture and click ok or choose a photo from gallery. Stacktrace shows a null pointer exception on the Uri.
My code for the activating the camera is as follows:
public void activateCamera(View view){
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// start the image capture Intent
startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if ((requestCode == CHOOSE_IMAGE_ACTIVITY_REQUEST_CODE || requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE)
&& resultCode == RESULT_OK && null != data) {
selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
Bitmap bits = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = inSampleSize;
try {
bits = BitmapFactory.decodeStream(new FileInputStream(picturePath),null,options);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Any idea what could be the problem?
Thanks!
You have to tell the camera, where to save the picture and remeber the uri yourself:
private Uri mMakePhotoUri;
private File createImageFile() {
// return a File object for your image.
}
private void makePhoto() {
try {
File f = createImageFile();
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mMakePhotoUri = Uri.fromFile(f);
i.putExtra(MediaStore.EXTRA_OUTPUT, mMakePhotoUri);
startActivityForResult(i, REQUEST_MAKE_PHOTO);
} catch (IOException e) {
Log.e(TAG, "IO error", e);
Toast.makeText(getActivity(), R.string.error_writing_image, Toast.LENGTH_LONG).show();
}
}
#Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
switch (requestCode) {
case REQUEST_MAKE_PHOTO:
if (resultCode == Activity.RESULT_OK) {
// do something with mMakePhotoUri
}
return;
default: // do nothing
super.onActivityResult(requestCode, resultCode, data);
}
}
You should save the value of mMakePhotoUri over instance states withing onCreate() and onSaveInstanceState().
Inject this extra into the Intent that called onActivityResult and the system will do all the heavy lifting for you.
File f = createImageFile();
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
Doing this makes it as easy as this to retrieve the photo as a bitmap.
private void handleSmallCameraPhoto(Intent intent) {
Bundle extras = intent.getExtras();
mImageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(mImageBitmap);
}
dont pass any extras, just define the path where you have placed or saved the file directly in onActivityResult
public void openCamera() {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = createImageFile();
boolean isDirectoryCreated = file.getParentFile().mkdirs();
Log.d("", "openCamera: isDirectoryCreated: " + isDirectoryCreated);

tempFileUri = FileProvider.getUriForFile(getActivity().getApplicationContext(),
"com.scanlibrary.provider", // As defined in Manifest
file);
} else {
tempFileUri = Uri.fromFile(file);
}
try
{
cameraIntent.putExtra("return-data", true);
startActivityForResult(cameraIntent, ScanConstants.START_CAMERA_REQUEST_CODE);
}
catch (Exception e)
{
}
}
private File createImageFile() {
clearTempImages();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new
Date());
File file = new File(ScanConstants.IMAGE_PATH, "IMG_" + timeStamp +
".jpg");
fileUri = Uri.fromFile(file);
return file;

frnds,on clicking on button i open camera for taking picture ,i take picture successfull and now only two option is coming after clicking pic,"save" and "Discard",there is not any option for attaching the camera clicked image so how to attach image and display image in next view?
my code is ...
public void function2(int id){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST||requestCode == SELECT_PICTURE) {
try{
try{
selectedImageUri = data.getData();
//OI FILE Manager
String filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
//DEBUG PURPOSE - you can delete this if you want
if(selectedImagePath!=null){
Intent i=new Intent(MainMenu.this,Imageprview.class);
startActivity(i);
System.out.println(selectedImagePath);
}
else
System.out.println("selectedImagePath is null");
if(filemanagerstring!=null)
System.out.println(filemanagerstring);
else System.out.println("filemanagerstring is null");
//NOW WE HAVE OUR WANTED STRING
if(selectedImagePath!=null)
System.out.println("selectedImagePath is the right one for you!");
else
System.out.println("filemanagerstring is the right one for you!");
}catch (NullPointerException e) {
// TODO: handle exception
} }catch (ArrayIndexOutOfBoundsException e) {
// TODO: handle exception
} }
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if(cursor!=null)
{
//HERE YOU WILL GET A NULLPOINTER IF CURSOR IS NULL
//THIS CAN BE, IF YOU USED OI FILE MANAGER FOR PICKING THE MEDIA
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
else return null;

IN DETAIL PROFILE ACTIVITY
public class detailProfile extends Activity{

YOU HAVE ANOTHER OPTION YOU CAN PASS THE IMAGE TO THROUGH THE INTENT AT THE TIME OF CREATING THE NEW INTENT AND AFTER THAT YOU CAN ACCESS THAT IMAGE THROUGH THE BUNDLE OBJECT IN THE NEW INTENT.
bytes[] imgs = ... // your image

There is no such option available.you can save file in to sdcard or any external storage
c the code i have done for saving image in external storage.
public void onClick(View v)
{

Hi guys, this code is working. For camera and stored into sd card:
public class CampicsaveActivity extends Activity
{
/** Called when the activity is first created. */
FrameLayout frm;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
frm=(FrameLayout)findViewById(R.id.preview);
Button btnCam=(Button)findViewById(R.id.buttonClick);
btnCam.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
// Intent detailActivity = new Intent(getBaseContext(),com.rodasys.profile.detailProfile.class);
// startActivity(detailActivity);
saveImage(0);
} });
}
public void saveImage(int IMAGE_CAPTURE)
{
try
{
FileOutputStream fos = openFileOutput("MyFile.jpeg", Context.MODE_WORLD_WRITEABLE);
fos.close();
File f = new File(getFilesDir() + File.separator + "MyFile.jpeg");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION,90);
startActivityForResult(intent,IMAGE_CAPTURE);
//startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE).putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f)),IMAGE_CAPTURE);
}
catch(IOException e)
{;}
}
#Override
