How to get preview of captured image through camera intent in android

Hi am capturing an image through camera intent it works good but my problem is that am not getting preview of that image
my requirement is very simple, after clicking of photo through camera it must ask me to SAVE or DISCARD this image if i press SAVE then it get save into sd card thats it...
here is my code
private void openCamera() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
capturedFile = new File(Environment.getExternalStorageDirectory(),
"tmp_nookster_profilepic"
+ String.valueOf(System.currentTimeMillis()) + ".jpg");
mImageCaptureUri = Uri.fromFile(capturedFile);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA_NO_CROP);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK)
return;
switch (requestCode) {
case PICK_FROM_CAMERA_NO_CROP: {
iu.SaveCapturedImage(BitmapFactory.decodeFile(capturedFile
.getAbsolutePath()));
try {
if (capturedFile.exists())
capturedFile.delete();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
break;
here "iu" is object of ImageUtility class and "SaveCapturedImage" is method to store that captured image in SdCard

You can get a preview of the captured File as this:
Bitmap getPreview(File image) {
final int THUMBNAIL_SIZE = 72;
BitmapFactory.Options bounds = new BitmapFactory.Options();
bounds.inJustDecodeBounds = true;
BitmapFactory.decodeFile(image.getPath(), bounds);
if ((bounds.outWidth == -1) || (bounds.outHeight == -1))
return null;
int originalSize = (bounds.outHeight > bounds.outWidth) ? bounds.outHeight
: bounds.outWidth;
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inSampleSize = originalSize / THUMBNAIL_SIZE;
return BitmapFactory.decodeFile(image.getPath(), opts);
}
then you can show the Bitmap in an ImageView and present the user with Save/Delete buttons.

You have to remove line from your code.
if (resultCode != RESULT_OK)
return;
Use following code :
if (resultCode == RESULT_OK)
{
try
{
Bitmap bitmap=null;
String imageId = convertImageUriToFile(imageUri,AddRecipes.this);
bitmap = BitmapFactory.decodeFile(imageId);
}}
public static String convertImageUriToFile (Uri contentUri, Activity activity)
{
String[] proj = { MediaStore.Images.Media.DATA };
CursorLoader cursorLoader = new CursorLoader(activity.getApplicationContext(),contentUri, proj, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

finish or cancel camera intent causes window leak

I use below code to start camera capture on a button clicked:
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(captureIntent, Variables.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
On activity result, I just simply start "crop" activity.
if (requestCode == Variables.CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
picUri = data.getData();
performCrop();
}
When the camera first started, I pressed the back button to go back to the caller activity (A.class). And then start another activity, say B.class, causes window leak. Sometimes when B.class is called, the screen keep flashing....What's wrong with the code? Please HELP! Many thanks.
There are some alert dialogs I created, but it is already dismissed.

Try this is working like charm with me
private String selectedImagePath = "";
final private int PICK_IMAGE = 1;
final private int CAPTURE_IMAGE = 2;
public 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;
}
public String getImagePath() {
return imgPath;
}
btnGallery.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), PICK_IMAGE);

} else if (requestCode == CAPTURE_IMAGE) {
selectedImagePath = getImagePath();
imgUser.setImageBitmap(decodeFile(selectedImagePath));
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}

int scale = 1;
while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >= REQUIRED_SIZE)
scale *= 2;
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeFile(path, o2);
} catch (Throwable e) {
e.printStackTrace();
}
return null;
}

#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} else
return null;
}

Android - Camera activity gets opened instead of picture gallery

I've created an activity that allows the user to add a picture to an ImageView in that activity. I've created a button, that opens a context menu for the activity and gives the user options to either pick a picture from the gallery or take a picture with camera.
If I choose the first option - to pick a picture from the gallery, it works without problems. Gallery is opened, I pick the picture, my activity is resumed and the picture is added to the ImageView.
Strange things start happening after choosing the second option, taking the picture and resuming to my activity:
If I open the context menu again and try to open the gallery, camera
activity gets opened instead
I close the camera activity and resume to my activity, "Complete action using" dialog is shown
I open the gallery, pick a picture and NullPointerException is thrown
Why am I having this behavior and an exception? I've tried searching for similar topics but haven't found a solution.
Below are the methods for my activity
public boolean onContextItemSelected(MenuItem item) {
super.onContextItemSelected(item);
switch(item.getItemId()) {
case R.id.cm_Select_picture: {
// TODO open gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, ""), RC_SELECT_PICTURE);
}
case R.id.cm_Take_picture: {
// TODO open camera
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, RC_TAKE_PICTURE);
}
default: return false;
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK) {
switch(requestCode) {
case RC_SELECT_PICTURE: {
Log.d(TAG, "Case select picture");
Uri selectedImageUri = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImageUri
, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
Bitmap pic = BitmapFactory.decodeFile(filePath);
goodsImage.setImageBitmap(pic);
}
case RC_TAKE_PICTURE: {
Log.d(TAG, "Case take picture");
if(data.getExtras().get("data") != null) {
Bitmap pic = (Bitmap) data.getExtras().get("data");
goodsImage.setImageBitmap(pic);
}
}
}
}
}

if (toRecycle != null) {

}
mImg = decodeFileIntoRequiredSize(getPath(getMediaUri(),this), requiredSizeForImage);
imgView.setImageBitmap(mImg);
}
public Bitmap decodeFileIntoRequiredSize(String filePath,int requiredSize){

Why i am not able to take image from camera but can able to get image from Gallery in android?

I am using this code to fetch Image from gallery:
fromGalleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
canvasPictureDialog.dismiss();
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);//
//startActivity(intent);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),10);
//finish();
}
});
And to take image from camera i use this code:
private static final int TAKE_PHOTO_CODE = 1;
private void takePhoto(){
final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(this)) );
startActivityForResult(intent, TAKE_PHOTO_CODE);
}
private File getTempFile(Context context){
//it will return /sdcard/image.tmp
//final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName() );
final File path = new File( Environment.getExternalStorageDirectory(), context.getPackageName());
if(!path.exists()){
path.mkdir();
}
return new File(path, "image.tmp");
}
And common code for onActivityResult is:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 10 && resultCode == Activity.RESULT_OK) {
Uri contentUri = data.getData();
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();
imagePath = cursor.getString(column_index);
//Bitmap croppedImage = BitmapFactory.decodeFile(imagePath);
tempBitmap = BitmapFactory.decodeFile(imagePath);
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
}
if(resultCode == RESULT_OK && requestCode==TAKE_PHOTO_CODE){
final File file = getTempFile(this);
try {
tempBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
// do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Now with using this code i am drawing the image on canvas:
if(!(imagePath==null))
{
//tempBitmap = BitmapFactory.decodeFile(imagePath);
//photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
canvas.drawBitmap (photoBitmap,0, 0, null);
}
But with that use, I am able to get Image from gallery but not from the camera. Why ??
Whats wrong in my code ??
Thanks.

Well, I have solve this problem for my own way.
There is a logical mistake. I have taken the if condition on imagePath variable which can not works for the taking image from camera.
I have taken one boolean Variable and set it for Taking Image from Camera and it works for me.
Anyway, Thanks for the Comments and help.
Thanks.

How to pick an image from gallery (SD Card) for my app?

This question was originally asked for Android 1.6.
I am working on photos options in my app.
I have a button and an ImageView in my Activity. When I click the button it would redirect to the gallery and I would be able to select an image. The selected image would appear in my ImageView.

Updated answer, nearly 5 years later:
The code in the original answer no longer works reliably, as images from various sources sometimes return with a different content URI, i.e. content:// rather than file://. A better solution is to simply use context.getContentResolver().openInputStream(intent.getData()), as that will return an InputStream that you can handle as you choose.
For example, BitmapFactory.decodeStream() works perfectly in this situation, as you can also then use the Options and inSampleSize field to downsample large images and avoid memory problems.
However, things like Google Drive return URIs to images which have not actually been downloaded yet. Therefore you need to perform the getContentResolver() code on a background thread.
Original answer:
The other answers explained how to send the intent, but they didn't explain well how to handle the response. Here's some sample code on how to do that:
protected void onActivityResult(int requestCode, int resultCode,
Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case REQ_CODE_PICK_IMAGE:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.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 filePath = cursor.getString(columnIndex);
cursor.close();
Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
}
}
}
After this, you've got the selected image stored in "yourSelectedImage" to do whatever you want with. This code works by getting the location of the image in the ContentResolver database, but that on its own isn't enough. Each image has about 18 columns of information, ranging from its filepath to 'date last modified' to the GPS coordinates of where the photo was taken, though many of the fields aren't actually used.
To save time as you don't actually need the other fields, cursor search is done with a filter. The filter works by specifying the name of the column you want, MediaStore.Images.Media.DATA, which is the path, and then giving that string[] to the cursor query. The cursor query returns with the path, but you don't know which column it's in until you use the columnIndex code. That simply gets the number of the column based on its name, the same one used in the filtering process. Once you've got that, you're finally able to decode the image into a bitmap with the last line of code I gave.

private static final int SELECT_PHOTO = 100;
Start intent
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
Process result
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream = getContentResolver().openInputStream(selectedImage);
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
}
}
}
Alternatively, you can also downsample your image to avoid OutOfMemory errors.
private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);
// The new size we want to scale to
final int REQUIRED_SIZE = 140;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE
|| height_tmp / 2 < REQUIRED_SIZE) {
break;
}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);
}

You have to start the gallery intent for a result.
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, ACTIVITY_SELECT_IMAGE);
Then in onActivityForResult, call intent.getData() to get the Uri of the Image. Then you need to get the Image from the ContentProvider.

Here is a tested code for image and video.It will work for all APIs less than 19 and greater than 19 as well.
Image:
if (Build.VERSION.SDK_INT <= 19) {
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(i, 10);
} else if (Build.VERSION.SDK_INT > 19) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 10);
}
Video:
if (Build.VERSION.SDK_INT <= 19) {
Intent i = new Intent();
i.setType("video/*");
i.setAction(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(i, 20);
} else if (Build.VERSION.SDK_INT > 19) {
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 20);
}
.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 10) {
Uri selectedImageUri = data.getData();
String selectedImagePath = getRealPathFromURI(selectedImageUri);
} else if (requestCode == 20) {
Uri selectedVideoUri = data.getData();
String selectedVideoPath = getRealPathFromURI(selectedVideoUri);
}
}
}
public String getRealPathFromURI(Uri uri) {
if (uri == null) {
return null;
}
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
if (cursor != null) {
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
return uri.getPath();
}

Do this to launch the gallery and allow the user to pick an image:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, IMAGE_PICK);
Then in your onActivityResult() use the URI of the image that is returned to set the image on your ImageView.

public class EMView extends Activity {
ImageView img,img1;
int column_index;
Intent intent=null;
// Declare our Views, so we can access them later
String logo,imagePath,Logo;
Cursor cursor;
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
String selectedImagePath;
//ADDED
String filemanagerstring;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img= (ImageView)findViewById(R.id.gimg1);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
//UPDATED
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
TextView txt = (TextView)findViewById(R.id.title);
txt.setText(imagePath.toString());
Bitmap bm = BitmapFactory.decodeFile(imagePath);
// img1.setImageBitmap(bm);
}
}
}
//UPDATED!
public String getPath(Uri uri) {
String[] projection = { MediaColumns.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
column_index = cursor
.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
imagePath = cursor.getString(column_index);
return cursor.getString(column_index);
}
}

public class BrowsePictureActivity extends Activity {
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
if( uri == null ) {
return null;
}
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
return uri.getPath();
}
}

For some reasons, all of the answers in this thread, in onActivityResult() try to post-process the received Uri, like getting the real path of the image and then use BitmapFactory.decodeFile(path) to get the Bitmap.
This step is unnecessary. The ImageView class has a method called setImageURI(uri). Pass your uri to it and you should be done.
Uri imageUri = data.getData();
imageView.setImageURI(imageUri);
For a complete working example you could take a look here: http://androidbitmaps.blogspot.com/2015/04/loading-images-in-android-part-iii-pick.html
PS:
Getting the Bitmap in a separate variable would make sense in cases where the image to be loaded is too large to fit in memory, and a scale down operation is necessary to prevent OurOfMemoryError, like shown in the #siamii answer.

call chooseImage method like-
public void chooseImage(ImageView v)
{
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, SELECT_PHOTO);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
if(imageReturnedIntent != null)
{
Uri selectedImage = imageReturnedIntent.getData();
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK)
{
Bitmap datifoto = null;
temp.setImageBitmap(null);
Uri picUri = null;
picUri = imageReturnedIntent.getData();//<- get Uri here from data intent
if(picUri !=null){
try {
datifoto = android.provider.MediaStore.Images.Media.getBitmap(this.getContentResolver(), picUri);
temp.setImageBitmap(datifoto);
} catch (FileNotFoundException e) {
throw new RuntimeException(e);
} catch (IOException e) {
throw new RuntimeException(e);
} catch (OutOfMemoryError e) {
Toast.makeText(getBaseContext(), "Image is too large. choose other", Toast.LENGTH_LONG).show();
}
}
}
break;
}
}
else
{
//Toast.makeText(getBaseContext(), "data null", Toast.LENGTH_SHORT).show();
}
