Android/Java: <input type="file" accept="image/*;capture=camera"> doesn't work anymore in WebView

How can I open the camera from a webview directly in html to take a picture or pick up a gallery photo with android? It seems that the

<input type="file" accept="image/*;capture=camera">

doesn't work anymore...

Here is my code:

main class:

     @Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    
                if (requestCode != INPUT_FILE_REQUEST_CODE || mFilePathCallback == null) {
                    super.onActivityResult(requestCode, resultCode, data);
                    return;
                }
    
                Uri[] results = null;
    
                // Check that the response is a good one
                if (resultCode == Activity.RESULT_OK) {
                    if (data == null) {
                        // If there is not data, then we may have taken a photo
                        if (mCameraPhotoPath != null) {
                            results = new Uri[]{Uri.parse(mCameraPhotoPath)};
                        }
                    } else {
                        String dataString = data.getDataString();
                        if (dataString != null) {
                            results = new Uri[]{Uri.parse(dataString)};
                        }
                    }
                }
    
                mFilePathCallback.onReceiveValue(results);
                mFilePathCallback = null;

                    if (null == this.mUploadMessage) {
                        return;
    
                    }
