I am creating a webview app. I want file chooser functionality from the webview. I successfully created the file chooser but it opens file manager to choose file.
Now I want camera to be open when user clicks on choose file.

The above code works fine but it opens file manager from where I can select an image. But I want to open camera from where user can directly click the image to upload.
Please help me :)
Instead of Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
Use ACTION_IMAGE_CAPTURE like this
/*************************** Camera Intent Start ************************/
// Define the file-name to save photo taken by Camera activity
String fileName = "Camera_Example.jpg";
// Create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");
// imageUri is the current activity attribute, define and save it for later usage
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
/**** EXTERNAL_CONTENT_URI : style URI for the "primary" external storage volume. ****/
// Standard Intent action that can be sent to have the camera
// application capture an image and return it.
Intent intent = new Intent( MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult( intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
/*************************** Camera Intent End ************************/

I have given file access permission to web view. But still SPA inside webiew is unable to open file explorer/unable to access media.
binding.admWebView.settings.allowFileAccess=true
binding.admWebView.settings.setSupportMultipleWindows(true)
binding.admWebView.settings.javaScriptCanOpenWindowsAutomatically = true
Try this -
1. Add permission on AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
