Questions:

I’m developing a mobile app with cordova/phonegap and I’ve installed Camera plugin. I am able to open the camera and click the image but after that app crashes. here is the crash log:

    java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=34, result=-1, data=null} to activity {com.phonegap.helloworld/com.phonegap.helloworld.CordovaApp}: java.lang.IllegalArgumentException: filename cannot be null

code that I have used to open the camera is :

   var pictureSource; // picture source
var destinationType; // sets the format of returned value
document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
  // alert("ready-----")
  pictureSource = navigator.camera.PictureSourceType;
  destinationType = navigator.camera.DestinationType;
}

function capturePhoto() {
  alert(navigator.camera);
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
    quality: 20,
    destinationType: destinationType.FILE_URI,
    targetWidth: 200,
    targetHeight: 200,
    saveToPhotoAlbum: true,
    sourceType: pictureSource.CAMERA
  });
}

function onPhotoDataSuccess(imageURI) {
  // alert("success--");
  var smallImage = document.getElementById('smallImage');
  smallImage.style.display = 'block';
  smallImage.src = imageURI;
  // smallImage.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
  alert('Failed because: ' + message);
}

The bug is already logged in Apache Cordova.

Help!!!

How to&Answers:

Try replacing your capturePhoto() function with this (this is working code from my own app):

function capturePhoto() {
    var options = {
        quality: 75,
        destinationType: Camera.DestinationType.FILE_URI,
        sourceType: Camera.PictureSourceType.CAMERA,
        mediaType: Camera.MediaType.CAMERA,
        encodingType: Camera.EncodingType.JPEG,
        targetWidth: 200,
        targetHeight: 200,
        saveToPhotoAlbum: true
    };
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, options);
}

Answer:

please change your destination type:

destinationType: destinationType.FILE_URI

to

destinationType: Camera.DestinationType.FILE_URI

if you required it as a base64-encoding image, then change destination type as:

destinationType: Camera.DestinationType.DATA_URL

also make sure that you have added the write external storage permission in your manifest file.

Answer:

The plugin is passing a null pointer to ExifInterface causing an exception, which didn’t happen in older plugins.

Try applying the following fix, also can you report the device Brand, Model and android version as well ?
