  options.sourceType = Camera.PictureSourceType.CAMERA;
} else {
  options.sourceType = Camera.PictureSourceType.PHOTOLIBRARY;
}

$cordovaCamera.getPicture(options).then(function (imageData) {
  console.log("IMAGE DATA");
  console.log(imageData);
  //alert("SUCCESS");
  $scope.user.image = "data:image/jpeg;base64," + imageData;
  console.log(JSON.stringify($scope.user));

  alert("ERRROR");
  alert(JSON.stringify(err));
  // An error occured. Show a message to the user
});
};



$scope.savePicture = function () {
  var options = {
    fileKey: "avatar",
    fileName: "image.jpg",

    alert("ERROR: " + JSON.stringify(err));
}, function (progress) {
    // constant progress updates
});

};

Thank in advice for your help

Answer 1

you are not calling return appropriately on your functions that return a promise. From a quick review, $scope.savePicture(); should be return $scope.savePicture();

and $cordovaFileTransfer.upload() should also be return $cordovaFileTransfer.upload()

I would start there and see if you start to make some progress.

Answer 2

I had to debug the entire application including the cat log of android and I found the problem.

The problem was that I am using Ionic with crosswalk and the version of FileTransfer that I was using does not support crosswalk.

I fix this problem just installing the last version of file transfer:

cordova-plugin-file-transfer 1.2.1 "File Transfer"
