OnActivityResult doesn't update ImageView using Picasso

Using following code to view captured image in an ImageView
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(this.requestCode == requestCode && resultCode == RESULT_OK) {
File imageFile = new File(Environment.getExternalStorageDirectory() + "/img.jpeg");
Picasso.with(MainActivity.this).load(imageFile).into(imageView);
}
}
Problem:
How Can I refresh ImageView in onActivityResult(...) as you can see I am using above code but always getting preview of old image, whereas i am getting new image inside storage

You can replace the code these lines of code for it:-
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(this.requestCode == requestCode && resultCode == RESULT_OK) {
File imageFile = new File(Environment.getExternalStorageDirectory() + "/img.jpeg");
Picasso.with(MainActivity.this)
.load(imageFile)
.memoryPolicy(MemoryPolicy.NO_CACHE)
.networkPolicy(NetworkPolicy.NO_CACHE)
.error(R.drawable.ic_lanucher)
.noFade()
.into(imageView)
}
}

If you want to load the captured image, you need to get bitmap from data i.e. your Intent object.
if (responseCode == RESULT_OK && data != null) {
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
if (bitmap != null) {
// Here you will get bitmap , set bitmap in imageview
}
}

How to display an image that the user just took with camera

I am trying to give the user the option to either choose an image from the phone's storage or take one with the phone's camera app and then display that image in an imageView. With the help of this and this question I am able to display the image when it is choosen from the storage. However if I choose to take a picture with camera although I don't get an error the image is not shown in the imageView.
The function for choosing the picture looks like:
public void choosePic(View view) {
Intent pickIntent = new Intent();
pickIntent.setType("image/*");
pickIntent.setAction(Intent.ACTION_GET_CONTENT);
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
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_PICTURE);
}
After that it is handled by
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == PICK_IMAGE && data != null && data.getData() != null) {
Uri _uri = data.getData();
//User had pick an image.
Cursor cursor = getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
image = (ImageView) findViewById(R.id.imageView);
image.setImageURI(_uri);
cursor.close();
}
super.onActivityResult(requestCode, resultCode, data);
}
EDIT
With #Murtaza Hussain's helps I was able to find a working solution:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i("requestCode",""+requestCode);
if(requestCode == PICK_IMAGE && resultCode==RESULT_OK && data != null && data.getData() != null) {
Uri _uri = data.getData();
//User had pick an image.
Cursor cursor = getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
image = (ImageView) findViewById(R.id.imageView);
image.setImageURI(_uri);
cursor.close();
}
else if(requestCode== PICK_IMAGE && resultCode==RESULT_OK && data.getData() == null){
Bundle extras = data.getExtras();
Bitmap thePic = extras.getParcelable("data");
image =(ImageView) findViewById(R.id.imageView);
image.setImageBitmap(thePic);
}
super.onActivityResult(requestCode, resultCode, data);
}

You need to add code for it in onActivityResult()
if(requestCode==0 && resultCode==RESULT_OK ){
Bundle extras = data.getExtras();
Bitmap thePic = extras.getParcelable("data");
image =(ImageView) findViewById(R.id.imageView);
image.setImageBitmap(thePic);
}

In your activity when to capture image from camera. write the below code.
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
mImageCaptureUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"/imageLarge"+System.currentTimeMillis()+".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, 111);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
In onActivityResult() write the below code..
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 111:
if(resultCode == RESULT_OK)
{
Log.v("","After camera capture path is --> "+mImageCaptureUri.toString().substring(8));
Bitmap bitmap=BitmapFactory.decodeFile(mImageCaptureUri.toString().substring(8));
image.setImageBitmap(bitmap);
}
else
{
}
}
}
Do not forget to add one permission.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
In case of any query, Please let me know. Thanks.

Captures the image from camera and load image into imageview of another activity

i am getting a problem in fetching an image captured by camera into image view of another activity so please, find out the problem.....
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
and the onActivityresult() is
protected void onActivityResult(int requestCode, int resultCode, Intent data,Uri mCapturedImageURI)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==CAMERA_REQUEST&&resultCode==RESULT_OK)
{
String[] projection = { MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(mCapturedImageURI, projection, null, null, null);
int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String picturepath = cursor.getString(column_index_data);
Log.d("TAG", "getLastImageId::path " + picturepath);
Intent camintent= new Intent(MainActivity.this,GalleryActivity.class);
camintent.putExtra("imagePath",picturepath );
startActivity(camintent);
}
}
and my another(receiving) activity is........
private void getData(){
String ps=getIntent().getStringExtra("imagePath");
img.setImageBitmap(BitmapFactory.decodeFile(ps));
}

protected void onActivityResult(int requestCode, int resultCode, Intent data,Uri mCapturedImageURI)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==CAMERA_REQUEST&&resultCode==RESULT_OK)
{
Bitmap bitmapImage = (Bitmap) intent.getExtras().get("data");
Intent camintent= new Intent(MainActivity.this,GalleryActivity.class);
camintent.putExtra("bitmap", bitmapImage);
startActivity(camintent);
}
}
And retrieve the Bitmap Image in second Activity
private void getData(){
Bitmap bitImage=getIntent().getParcelableExtra("bitmap");
img.setImageBitmap(bitImage);
}

Look here for an example on how to launch the camera and then retrieve the image:
Capture Image from Camera and Display in Activity
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
If you want to pass the results between two different activities after receiving the image from the camera, you could save the bitmap as a file and then read it in the second activity.

how to get bitmap uri in android mobile device using java

i am implemented this code image upload device only how can retrieve bitmap uri
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, ACTIVITY_RESULT_IMAGE_SELECTED);
protected void onActivityResult(int requestCode, int resultCode, Intent intent,Intent data, CharSequence Uri)
{
super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == ACTIVITY_RESULT_IMAGE_SELECTED)
{
if (resultCode == RESULT_OK) {
Uri uri = intent.getData();
Object mBitmap = MediaStore.EXTRA_OUTPUT; //Media.//getBitmap(this.getContentResolver(),uri);
//EditText images=(EditText) findViewById(R.id.EditTextImages);
// mImageUploadAdapter.addImage(uri);
// mImageUploadGridView.invalidateViews();
}
} i am implementing this code

intent.getData() will return the URI of the Bitmap. If your question is about how you are to create a Bitmap Object from this URI you can take a look here.

Android camera intent losing reference of Imageview in Lollipop

I have an activity in which i am calling intent of camera on click, but when I capture image and get back to the activity result my Image view reference is null. I am getting URI correctly. This happens in android Lollipop.
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(captureIntent, 1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
Bundle extras = data.getExtras();
Bitmap thePic = extras.getParcelable("data");
//retrieve a reference to the ImageView
Log.i("dataa",String.valueOf(thePic));
Log.i("dataaimg",String.valueOf(image));
Log.i("dataaimgno",String.valueOf(imageno));
image.setImageBitmap(thePic); // here is the problem image reference is null when get back here
}
}
This code is working fine in versions below lollipop.

Try this:
private static final int CAPTURE_IMAGE_ACTIVITY_REQ = 0;
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAPTURE_IMAGE_ACTIVITY_REQ );
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQ) {
if (resultCode == RESULT_OK) {
Bitmap bp = (Bitmap) data.getExtras().get("data");
image = setImageBitmap(bp);
}
}
