Android Question B4A problem webview dont open camera from asp:fileupload

1. Please don't post questions as polls.
2. Post code as text, not screenshot.

Why use WebView for this? You will encounter many issues with this approach. You can use the Camera library or the intent based solution to take a photo.

Try to add the camera permission with the manifest editor:

In the manifest editor, I entered the permission line, compiled and replaced the version in the mobile:


'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddPermission(android.permission.CAMERA)
AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.


But the result remains the same, the camera does not open.

It will be difficult to implement it with WebView only. You need to implement onShowFileChooser on Android 5+ and openFileChooser on older versions. I don't think that WebViewExtra2 implements these methods.

As an alternative you can implement the file upload outside of WebView with OkHttpUtils2. You will have full control and it will also be more reliable.

When I do the DEBUG in the application, I notice that the WebViewxtras2 library shows in the debug panel:

"AcceptType: image / *"
"Capture: *"

Even if I change in the html to set the FileUpload with the parameter camera, the library disregards the command that I inform "capture" as below:

<Asp: FileUpload ID = "img_Despesa" runat = "server"
Accept = "image / *" width = "1" Height = "1" onChange = 'JSimg_pathUrl (this);' Capture = "camera" />

Interestingly the parameter "AcceptType" the library catches correctly but disregards the "Capture"

Is there any way to set this parameter to "Capture: camera" instead of "Capture: *"?
