MediaCapture API captureVideo crashes app (edited)

maxpaj · January 29, 2017, 10:53am

I’m having an issue with my Iconic 2 app I just started developing. I’m previewing the app through Ionic View, but it crashes when I make a call to the MediaCapture API (from Ionic Native). It only produces this error on the Android device I’m using - the iOS device works fine…

I’m now installing Android Studio and want to attach some sort of debugger to the Android device to extract logs or stack trace. I imagine it might not work since I’m not developing Ionic View, but my own app running inside Ionic View.

Has anyone stumbled across this problem? I would appreciate any help I can get

So I’ve managed to pull some logs from the phone using ADB (Android Debugging Bridge). I installed Android SDK and the plugin Android Platform Tools where ADB is one of the tools.

Using adb logcat I could see the traces for everything going on in the phone, so I extracted this from the logs:

I looked up this code in the repository:

github.com

apache/cordova-plugin-media-capture/blob/master/src/android/Capture.java#L432


      
              req.results.put(mediaFile);
          
              checkForDuplicateImage();
          
              if (req.results.length() >= req.limit) {
                  // Send Uri back to JavaScript for viewing image
                  pendingRequests.resolveWithSuccess(req);
              } else {
                  // still need to capture more images
                  captureImage(req);
              }
          }
          
          public void onVideoActivityResult(Request req, Intent intent) {
              // Get the uri of the video clip
              Uri data = intent.getData();
              if (data == null) {
                  pendingRequests.resolveWithFailure(req, createErrorObject(CAPTURE_NO_MEDIA_FILES, "Error: data is null"));
                  return;
              }

github.com

apache/cordova-plugin-media-capture/blob/master/src/android/Capture.java#L395


      
                  pendingRequests.resolveWithFailure(req, createErrorObject(CAPTURE_NO_MEDIA_FILES, "Error: data is null"));
                  return;
              }
          
              // Create a file object from the uri
              JSONObject mediaFile = createMediaFile(data);
              if (mediaFile == null) {
                  pendingRequests.resolveWithFailure(req, createErrorObject(CAPTURE_INTERNAL_ERR, "Error: no mediaFile created from " + data));
                  return;
              }
          
              req.results.put(mediaFile);
          
              if (req.results.length() >= req.limit) {
                  // Send Uri back to JavaScript for listening to audio
                  pendingRequests.resolveWithSuccess(req);
              } else {
                  // still need to capture more audio clips
                  captureAudio(req);
              }
          }

Not sure where to continue from here, but I’ll keep this thread updated.

it doesnt look like ionic view supports MediaCapture plugin

maxpaj · January 29, 2017, 5:36pm

Ahhh, nice find! Then I won’t worry about it for now. Thanks

Actually I just noticed that it is listed under that page, as “Capture”. However, that version is 1.3.0.

What is the best approach to find out what broke it? Which of the native API calls are not supported in Ionic View?

My way forward is trying out MediaCapture 1.3.0 to see if that works with Ionic View.

EDIT: I tried that out, but it produced the same error:

What I’m curious about here is that the line numbers are the exact same… Which give me the suspicion that it is still using 1.4.x. How do I make sure I’m using the correct version?

This is the snippet from my fetch.json:

    "cordova-plugin-media-capture": {
        "source": {
            "type": "registry",
            "id": "cordova-plugin-media-capture@1.3.0"
        },
        "is_top_level": true,
        "variables": {}
    }

i would confirm it works outside of Ionic View so that you can isolate if the problem is in your code or not

maxpaj · January 30, 2017, 3:01pm

Yeah exactly, I was thinking the same. The thing is I just don’t know how to do that do you have any suggestions?

I’ll try this: https://ionicframework.com/docs/guide/testing.html
