Camera does not open in WebView

Question

I need to work in WebViewwith Camera. I have implemented some code HTMLthat uploads a file from Assetsto WebView, and my HTMLfile contains Buttonto upload the image to the server. Images are selected from the gallery itself and photographed from the camera. but when I try with the camera, it does not open. I do not know why? In addition, I added the required camera resolution to manifest.xml.

please, my one question is, where am I going wrong?

Answer 1

I got your problem, I think you need to add <uses-feature>for the camera, for example:

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />

, permission , features, , .

Answer 2

(html5):

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

:

<uses-permission android:name="android.permission.CAMERA" />

- Android, :

• Java
• DOM

• PermissionRequest ( , - )

  webview.getSettings().setJavaScriptEnabled(true);
  webview.getSettings().setDomStorageEnabled(true);
  webview.getSettings().setPluginState(WebSettings.PluginState.ON);
  
  webview.setWebChromeClient(new WebChromeClient(){
          // Need to accept permissions to use the camera
          @Override
          public void onPermissionRequest(final PermissionRequest request) {
              L.d("onPermissionRequest");
              if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                   request.grant(request.getResources());
              }
          }
      });

val permission = Manifest.permission.CAMERA
                    val grant = ContextCompat.checkSelfPermission(this@WebViewActivity, permission)
                    if (grant != PackageManager.PERMISSION_GRANTED) {
                        val permission_list = arrayOf(permission)
                        ActivityCompat.requestPermissions(this@WebViewActivity, permission_list, 1);
                                           }
