I am trying to connect Azure to Android Studios. I have followed the tutorial on Azure and created a mobile service. It then gave me some code to add to my app so that they are connected. However, the code is throwing an exception which I cannot figure out. I have searched the internet from head to toe and cannot find an answer. I think it has something to do with the dependencies or the way the library was imported (which was by pasting a jar file into the libs folder and adding a dependency).
The code throwing causing the exception (provided by Azure):
try {
mClient = new MobileServiceClient(
"https://atm.azure-mobile.net/",
"JWjetFMUVaAXzHmqDVqhkkRhTGGjeW70",
this
);
Item item = new Item();
item.Text = "Awesome item";
mClient.getTable(Item.class).insert(item, new TableOperationCallback<Item>() {
public void onCompleted(Item entity, Exception exception, ServiceFilterResponse response) {
if (exception == null) {
// Insert succeeded
Toast.makeText(context, "WOOHOO", Toast.LENGTH_LONG).show();
} else {
// Insert failed
Toast.makeText(context, "FAILED", Toast.LENGTH_LONG).show();
}
}
});
}
catch(MalformedURLException d) {
}
The exception:

I have solved the problem by updating the .jar file. Although the Microsoft documentation told me to get:
'gson:2.2.2'
This version does not work. Instead I downloaded a newer version:
'gson:2.3.1'
This .jar file solves the issue
