How can I update Gallery After a Photo had been taken?

I created a program to capture a photo but when i look at it in the Photo Gallery it does not appear immediately.
I Already used the command provided in the other questions in this site which is similar to this Code:
"sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));"
this is my entire code:
enter code here

Fragment Upload Image to ImageButton

I have tried many different approaches but none of them seem to help, so the problem is the following:
Image isn't uploading to imageButton. I have the path and I have checked it via debugger, added some Toasts to that the fragment gets to the onActivityResult and it does, but the image isn't uploading. Any ideas?

OnClick goto new Activity in GridView Android

I take a photo from the camera and store them in a GridView, now when i view them there is no OnClick function to Enlarge or Goto new Activity to Enlarge the selected image, Here's the code:
Where to implement the OnClick method to take the selected image to a new Activity and enlarge it
package com.example.veeresh.myphotogallery;
public class Photo_1 extends AppCompatActivity implements OnClickListener {
Button captureBtn = null;
final int CAMERA_CAPTURE = 1;
private Uri picUri;
private DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

if (listOfImagesPath != null) {
grid.setAdapter(new ImageListAdapter(this, listOfImagesPath));
}
}
#Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);

//we will handle the returned data in onActivityResult
Toast.makeText(this, "Launching Camera", Toast.LENGTH_SHORT).show();
startActivityForResult(captureIntent, CAMERA_CAPTURE);
} catch (ActivityNotFoundException anfe) {
//display an error message
String errorMessage = "Whoops - your device doesn't support capturing images!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
}

if (resultCode == RESULT_OK) {
//user is returning from capturing an image using the camera

File[] files = f.listFiles();
Arrays.sort(files);
for (int i = 0; i < files.length; i++) {

continue;
tFileList.add(file.getPath());

}

Use setOnItemClickListener of girdview.
grid = (GridView) findViewById(R.id.gridviewimg);
grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(this, "you clicked at : " + position, Toast.LENGTH_LONG).show();
// put your intent here to open activity
}
});

put this code inside your onCreate(...) method.
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// do your stuff.
}
});

android custom listview with gallery images

I'm trying to add all the images contained in a folder in my custom listview, where I show a thumbnail of the photo and a little description.

Thanks a lot for your precious support!
Greetings,
Michele.

I'm using this library to load images from an URL
https://github.com/thest1/LazyList

try using code like this in Your adapter:
File img = new File("/sdcard/image.jpg");
if(img.exists()){
Bitmap bitmap = BitmapFactory.decodeFile(img.getAbsolutePath());
holder.imageView.setImageBitmap(bitmap);
}

Failed Binder Transaction after setting bitmaps

I can capture an image, either through camera or gallery. I also have two imageviews to set the captured images to it. But I always get the failed binder transaction when I try to start an intent with the passed two compressed bitmaps:
public class PostFragment extends Fragment implements OnClickListener {
View post_view;
Button button1, button0;
ActionBar actionBar;
private Uri mImageCaptureUri;
private ImageView mImageView, mImageView2;
private AlertDialog dialog;
private String imagepath = null;
Bitmap bitmap, bitmap1, bitmap2, bitmap_image1, bitmap_image2;
String krt, krt1, krt2;
private static final int PICK_FROM_CAMERA = 1;
private static final int PICK_FROM_FILE = 3;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
post_view = inflater.inflate(R.layout.postoffer_fragment_layout,
container, false);
getActivity().getActionBar().setIcon(R.drawable.ic_offer);
button1 = (Button) post_view.findViewById(R.id.button1);
button1.setOnClickListener(this);
button0 = (Button) post_view.findViewById(R.id.button0);
button0.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.show();
}
});
captureImageInitialization();
mImageView = (ImageView) post_view.findViewById(R.id.imageView1);
mImageView2 = (ImageView) post_view.findViewById(R.id.imageView2);
return post_view;
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.button1) {
// setText() sets the string value of the TextView
Intent intent = new Intent(getActivity(), OfferInformation.class);
if (krt1 != "" && krt2 != "") {
intent.putExtra("image", krt1);
intent.putExtra("image2", krt2);
startActivity(intent);
}
}
private void captureImageInitialization() {
final String[] items = new String[] { "Take from camera",
"Select from gallery" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.select_dialog_item, items);

builder.setTitle("Select Image");
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if (item == 0) {
Intent intent = new Intent(
"android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, PICK_FROM_CAMERA);
} else {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Complete action using"), PICK_FROM_FILE);
}
}

mImageView.setImageBitmap(bitmap1);
