Camera access permission

[moirrer]

Is there a way to give my android app camera access permission? Like mWebView.setGeolocationEnabled(true) for location permission, is there anything like it to allow the camera access?

Thanks for your question!

It's actually not as easy as with the geolocation, unfortunately. But there are still ways to do it:

First, there's HTML5 media capture. Adding this to your WebView is possible, but requires some work. You can read more about that here:

• https://github.com/delight-im/Android-AdvancedWebView/issues/10
• https://developer.mozilla.org/en-US/docs/Web/Guide/API/Camera

Apart from that, there's a newer API called navigator.getUserMedia() in JavaScript. But this API is not supported before Android 5.0 -- and even then, it's only supported with the "webkit" prefix. You can read more about that API here:

• http://davidwalsh.name/browser-camera
• http://caniuse.com/#feat=stream

Hope that helps!

Manage to make it work! Once you have your camera capture working in webbrowser, to grant the camera permission:

public void iniciaWebView(){
    mWebView = (AdvancedWebView) findViewById(R.id.webview);
    mWebView.setListener(this, this);
    mWebView.setGeolocationEnabled(true);
    mWebView.addHttpHeader("X-Requested-With", appNomeLogs);

    mWebView.setWebChromeClient(new WebChromeClient() {
        @Override
        public void onPermissionRequest(final PermissionRequest request) {
            Log.i(appNomeLogs, "|> onPermissionRequest");

            MainActivity.this.runOnUiThread(new Runnable(){
                @TargetApi(Build.VERSION_CODES.LOLLIPOP)
                @Override
                public void run() {
                    Log.i(appNomeLogs, "|> onPermissionRequest run");
                    request.grant(request.getResources());
                }// run
            });// MainActivity

        }// onPermissionRequest
    });// setWebChromeClient

    mWebView.loadUrl(url);
}// iniciaWebView

Only tested in android 5 so far.

obs: not forgeting the manifest

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

Thanks for sharing! Great that it worked for you :)

But getting this to work on Android 4.0+ as well and saving the captured image on the file system probably requires some more work, right?

@moirrer Looking at your code it looks like this will auto-accept all permissions requested. When you allow external websites in your webview you don't have control off, I think you don't want this without the users permission.

[ocram]

@RoelRoel That is correct. You should only ever do this if your own website is the only site that will be displayed in the WebView. But even then, you have to pay attention because external links might lead to external sites again.

For what it's worth, I ended up using parts of https://github.com/mgks/Os-FileUp to get it working.
