[Android] Problem sending multiple images to my server. The server only receive the last image. It works perfectly on iOS

[marseca]

I send three images to my server with this code:

var obj = {
            uploadUrl:  Globals.BASE_URL + Globals.API_PATH + q,
            method: 'POST', // default 'POST',support 'POST' and 'PUT' 
            headers: {
                'Accept': 'application/json',
                'Authorization': 'application/galickho',
            },
            fields: {
                email:"[email protected]",
            },
            files: this.state.images
        };
console.log(obj.files);   // This is correct: 3
FileUpload.upload(obj, function(err, result) {
                console.log('upload:', err, result);
                if(err != null){
                    reject(ErrorManager.getError("http_error"));
                }else{
                    resolve(result);
                }
            })

And my server returns the contents of the $_FILES variable. If I sent images from an iOS device, my server returns three images. But if I have sent the images from an Android device, only it returns the last image...

Simple PHP Code:
echo json_encode($_FILES);

Device: ACER A3-A20FHD
