How to get path of picture in onActivityresult (Intent data is null)

How to get path of picture in onActivityresult (Intent data is null) - android

I have to launch the camera, and when the users has done the picture, I have to take it and show it in a view.
Looking at http://developer.android.com/guide/topics/media/camera.html I have done:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bLaunchCamera = (Button) findViewById(R.id.launchCamera);
bLaunchCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG, "lanzando camara");
//create intent to launch camera
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); //create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); //set the image file name
//start camera
startActivityForResult(intent, CAMERA_REQUEST);
}
});
/**
* Create a File Uri for saving image (can be sued to save video to)
**/
private Uri getOutputMediaFileUri(int mediaTypeImage) {
return Uri.fromFile(getOutputMediaFile(mediaTypeImage));
}
/**
* Create a File for saving image (can be sued to save video to)
**/
private File getOutputMediaFile(int mediaType) {
//To be safe, is necessary to check if SDCard is mounted
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
(String) getResources().getText(R.string.app_name));
//create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d(TAG, "failed to create directory");
return null;
}
}
//Create a media file name
String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmmss").format(new Date());
File mediaFile;
if (mediaType == MEDIA_TYPE_IMAGE) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg");
} else {
return null;
}
return mediaFile;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == CAMERA_REQUEST) {
if(resultCode == RESULT_OK) {
//Image captured and saved to fileUri specified in Intent
Toast.makeText(this, "image saved to:\n" + data.getData(), Toast.LENGTH_LONG).show();
Log.d(TAG, "lanzando camara");
} else if(resultCode == RESULT_CANCELED) {
//user cancelled the image capture;
Log.d(TAG, "usuario a cancelado la captura");
} else {
//image capture failed, advise user;
Log.d(TAG, "algo a fallado");
}
}
}
When the picture has been done, the app crashes when it try to send the 'Toast' info because 'data' is null.
But if I debug the app I can see that the image has been saved.
So my question is: How can I get the path in the onActivityResult?

The problem you are facing is that, whenever we select an image from camera intent, it may finish the activity which called it, so imageUri object you created will be null while you return.
so you need to save it when you exit the activity (to go to camera intent), like this -
/**
* Here we store the file url as it will be null after returning from camera
* app
*/
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// save file url in bundle as it will be null on screen orientation
// changes
outState.putParcelable("file_uri", mImageUri);
}
and retrieve it back when you come back to the activity -
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// get the file url
mImageUri = savedInstanceState.getParcelable("file_uri");
}
Your code looks fine, you only need to add this change in it.

Here is code I have used for Capturing and Saving Camera Image then display it to imageview. You can use according to your need.
You have to save Camera image to specific location then fetch from that location then convert it to byte-array.
Here is method for opening capturing camera image activity.
private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;
private void captureCameraImage() {
Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(Environment.getExternalStorageDirectory(), "POST_IMAGE.jpg");
chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
imageToUploadUri = Uri.fromFile(f);
startActivityForResult(chooserIntent, CAMERA_PHOTO);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_PHOTO && resultCode == Activity.RESULT_OK) {
if(imageToUploadUri != null){
Uri selectedImage = imageToUploadUri;
getContentResolver().notifyChange(selectedImage, null);
Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
if(reducedSizeBitmap != null){
ImgPhoto.setImageBitmap(reducedSizeBitmap);
Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
uploadImageButton.setVisibility(View.VISIBLE);
}else{
Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}else{
Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}
}
Here is getBitmap() method used in onActivityResult(). I have done all performance improvement that can be possible while getting camera capture image bitmap.
private Bitmap getBitmap(String path) {
Uri uri = Uri.fromFile(new File(path));
InputStream in = null;
try {
final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
in = getContentResolver().openInputStream(uri);
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(in, null, o);
in.close();
int scale = 1;
while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
IMAGE_MAX_SIZE) {
scale++;
}
Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);
Bitmap b = null;
in = getContentResolver().openInputStream(uri);
if (scale > 1) {
scale--;
// scale to max possible inSampleSize that still yields an image
// larger than target
o = new BitmapFactory.Options();
o.inSampleSize = scale;
b = BitmapFactory.decodeStream(in, null, o);
// resize to desired dimensions
int height = b.getHeight();
int width = b.getWidth();
Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);
double y = Math.sqrt(IMAGE_MAX_SIZE
/ (((double) width) / height));
double x = (y / height) * width;
Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
(int) y, true);
b.recycle();
b = scaledBitmap;
System.gc();
} else {
b = BitmapFactory.decodeStream(in);
}
in.close();
Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
b.getHeight());
return b;
} catch (IOException e) {
Log.e("", e.getMessage(), e);
return null;
}
}
I hope it helps!

Dealing with out of memory error for camera intent imageView preview

I am working on an android app that has to take picture and display a preview before it is uploaded to a sever. (Sounds easy, right? At least so i thought).
My problem i think is the out of memory error because sometimes it manages to display the picture but most times the app just closes.
Here is how is use the intent:
imageCaptureButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
stamp = accNum[pos] + "_" + s.format(new Date());
File f = new File(Environment.getExternalStorageDirectory(), stamp + ".jpg");
chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
imageToUploadUri = Uri.fromFile(f);
imagePath = f.getPath();
stopFusedLocation();
startActivityForResult(chooserIntent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
});
Here is how i decode the captured image
private Bitmap getBitmap(String path) {
Uri uri = Uri.fromFile(new File(path));
InputStream in = null;
try {
final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
in = getActivity().getContentResolver().openInputStream(uri);
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(in, null, o);
in.close();
int scale = 1;
while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
IMAGE_MAX_SIZE) {
scale++;
}
Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);
Bitmap b = null;
in = getActivity().getContentResolver().openInputStream(uri);
if (scale > 1) {
scale--;
// scale to max possible inSampleSize that still yields an image
// larger than target
o = new BitmapFactory.Options();
o.inSampleSize = scale;
b = BitmapFactory.decodeStream(in, null, o);
// resize to desired dimensions
int height = b.getHeight();
int width = b.getWidth();
Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);
double y = Math.sqrt(IMAGE_MAX_SIZE
/ (((double) width) / height));
double x = (y / height) * width;
Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
(int) y, true);
b.recycle();
b = scaledBitmap;
System.gc();
} else {
b = BitmapFactory.decodeStream(in);
}
in.close();
Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
b.getHeight());
return b;
} catch (IOException e) {
Log.e("", e.getMessage(), e);
return null;
}
}
Here is how i handle activity result
/**
* Receiving activity result method will be called after closing the camera
* */
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
if(imageToUploadUri != null){
Uri selectedImage = imageToUploadUri;
getActivity().getContentResolver().notifyChange(selectedImage, null);
Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
if(reducedSizeBitmap != null){
bkl.setImageBitmap(reducedSizeBitmap);
}else{
Toast.makeText(getContext(),"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}else{
Toast.makeText(getActivity(),"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}
}
Please don't say its a duplicate question because i have read through all the other questions about this and nothing seems to work. I even tried android:largeHeap = true in manifest, then restoring instance state, everything, nothing seems to work.
Any help appreciated.

Check the LeakCanary and see where u have leaks on activity.
Also u have like spaghetti code:
}else{
Toast.makeText(getContext(),"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}else{
Toast.makeText(getActivity(),"Error while capturing Image",Toast.LENGTH_LONG).show();
getAplication(); getContext();
this is no way. Create the Context, or Activity and repair everything.

If passing imageToUploadUri is not important to pass with intent then you can get thumbnail in intent's extras using (Bitmap) intent.getExtras().get("data"). Otherwise, check that imageToUploadUri.getPath() returns correct path. You can use method below to get path of that image from uri.
public String getPathFromURI(Uri uri){
String filePath = "";
String[] filePahColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, filePahColumn, null, null, null);
if (cursor != null) {
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(filePahColumn[0]);
filePath = cursor.getString(columnIndex);
}
cursor.close();
}
return filePath;
}
May this helps.

Facing an issue with using camera by intent in Android

I want to take a picture and store it in a folder with the name Medit via my app. When my app starts, it should be able to pull all the pictures from this folder and display it directly. So the data storage path must be set and stored as part of the app. Here is what I have done so far
public void CaptureImage(){
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mediaStorageDir =new File(Environment.getExternalStorageDirectory(),"MyAppName");
mUri =Uri.fromFile(mediaStorageDir+"IMG"+System.currentTimeMillis() + ".jpg");
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mUri);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap bm = BitmapFactory.decodeFile(mUri.getPath());
imgVIew.setImageBitmap(bm);
}else Log.d("capture", "FAILED");}
Issue is, irrespective what i change mUri to the picture is being stored in DCIM/ camera images with the default naming convention. In the onActivityResult I am capturing the image. Issue is Im not able to comtrol where it is being stored and as what name. I need to
1) Capture an image via intent, store it in a location with a custom name.
2) Everytime the app opens, it should go to that same storage location and pull out the pictures and display them one by one.

irrespective what i change mUri to the picture is being stored in DCIM/ camera images with the default naming convention
Most likely, that is a bug in that camera app. Most camera apps will honor EXTRA_OUTPUT properly. However, there is no enforcement mechanism to ensure that a camera app will honor EXTRA_OUTPUT.
However, please do not use string concatenation to create a file path, and make sure that you create your directories. IOW, replace:
mediaStorageDir =new File(Environment.getExternalStorageDirectory(),"MyAppName");
mUri =Uri.fromFile(mediaStorageDir+"IMG"+System.currentTimeMillis() + ".jpg");
with:
mediaStorageDir=new File(Environment.getExternalStorageDirectory(),"MyAppName");
mediaStorageDir.mkdirs();
mUri=Uri.fromFile(new File(mediaStorageDir, "IMG"+System.currentTimeMillis() + ".jpg"));
It is possible that changing this code will make your app more compatible with this particular camera app, but there are no guarantees that all camera apps will behave as you wish.
I need to...
Your code is written to give you what you want. However, you are invoking a third-party app with the ACTION_IMAGE_CAPTURE Intent. There are thousands of camera apps, both pre-installed and available for download from the Play Store and elsewhere. Many will have properly-working ACTION_IMAGE_CAPTURE implementations. Some will not.
Either:
Detect that the image is not at your desired path and let the user know that their camera app is broken. Then, suggest that they install some third-party camera app that you have tested. Or,
Stop using ACTION_IMAGE_CAPTURE and work with the camera APIs directly, though this is rather difficult.

Your pictures are being save in default path because the path you are providing is wrong. Use the following code.
File mediaStorageDir =new File(Environment.getExternalStorageDirectory(),"MyAppName");
if(!mediaStorageDir.exists())
mediaStorageDir.mkdir();
Uri mUri = Uri.fromFile(new File(mediaStorageDir.getAbsolutePath() + "/IMG" + System.currentTimeMillis() + ".jpg"));
LogHelper.LogI("path", mUri.getPath());

Please try th following code it's working for me.
public class CaptureImage extends Activity {

Use ExifInterface to read photo EXIF tags & rotate bitmap when you show it. You may check this for some sample code, however it needs to be edited & cleaned a bit

Camera activity returning null android

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);

dispatchTakePictureIntent();
}
#Override

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) {

{

{
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);
}

Try this tutorial. It works for me and use permission as usual in manifesto & also
check permission
https://androidkennel.org/android-camera-access-tutorial/

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.
