Select Multiple Images and Display in Multiple ImageView

I want to select 4 images from phone gallery and display them in 4 imageviews, so far below code is working fine by selecting 4 buttons individually.
Now i want to implement to select 4 images with 1 button and get them displayed in 4 imageview simulatenously, i am stuck here and have done many google search and found a solution by using getClipData below but after many trial and error still not working, can someone enlighthen me and appreicate your help.
if(data.getClipData() != null) {
int count = data.getClipData().getItemCount(); //evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
for(int i = 0; i < count; i++) {
// Uri filepath = data.getClipData().getItemAt(i).getUri();
}
//do something with the image (save it to some directory or whatever you need to do with it here)
}
} else if(data.getData() != null) {
String imagePath = data.getData().getPath();

You can do it in the following way . I have used viewBinding in this project and have used the new activity contracts for getting images since startActivity is deprecated .The code is as follows .
public class MainActivity extends AppCompatActivity {
//Getting the binding
ActivityMainBinding binding;
//Defining a contract and assiging it to imageView
ActivityResultLauncher<String> mGetMultipleContent = registerForActivityResult(new ActivityResultContracts.GetMultipleContents(),
new ActivityResultCallback<List<Uri>>() {
#Override
public void onActivityResult(List<Uri> result) {
for (int i = 0; i < result.size(); i++) {
binding.imgone.setImageURI(result.get(0));
binding.imgtwo.setImageURI(result.get(1));
binding.imgthree.setImageURI(result.get(2));
binding.imgfour.setImageURI(result.get(3));
}
}
});
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
//Launching contract for getting images
binding.addButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mGetMultipleContent.launch("image/*");
}
});
}
}

This is my class and i am trying to capture an image on click a button and then save into directory after that show into imageview and then want to send to server,i hope you will help me as a best programmer.

this question may be a duplicate of this.
Basically, when you pass an OutPut file to the intent, you cannot read data from extra, you have to make sure that CameraApplication has access to your files. You are getting this exception, because CameraApplication cannot save the file on your directory, you need to add a file provider...
Please make your code is same as the base android documentation.

Try This
public void getFile(View view) {
if (ContextCompat.checkSelfPermission(UploadDocumentActivity.this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(UploadDocumentActivity.this,new String[]{Manifest.permission.CAMERA},
MY_CAMERA_PERMISSION_CODE);
} else {
Intent i=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir=
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
String pictureNm = getPictureName();
File output=new File(dir, pictureNm);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}

Application crashes every time camera open

I've written an application which should take picture and record video and then show it on the screen. When trying it on phone the camera won't work but works in emulator.
When executing the app this is what exactly happens:
Every time I clicked on the button to open the camera, the app stopped and the error it display is Appname has stopped, Open app again
When I clicked on Open app again it return to normal state
I have granted the camera permission in my program
below is my code:

You need to first convert your image url to a Uri, and then load it using Picasso the same way you did.
As I am seeing in the log you are using just the same url string in the load method parameter. So kindly convert image url (String) to Uri and then try it.
Hope this will work. Please do update.

You should do:

public CommonChattingAttachmentCustomAdapter(OrderedRealmCollection<ChatCommon> results) {
super(results);
}
and
public void setAdapter() {
//lv= (ListView) findViewById(R.id.Listview_common);
//final CommonChatRealmHelper helper = new CommonChatRealmHelper(realm);
//helper.retrieveFromDB();
adapter = new CommonChattingAttachmentCustomAdapter(realm.where(CommonChat.class).findAll());
//adapter = new CommonChattingAttachmentCustomAdapter(this, helper.justRefresh());
lv.setAdapter(adapter);
See which code was commented out, that should generally be deleted entirely
