why volley didnt read my url string completely - android-volley

Question

I have been calling this API long enough. But now, volley cannot read my URL string completely using the same code as before, except that I put sendmsgnow() function in my adapter. It's working when I put that URL in my browser.
P.s:-I have changed the password as it's a paid sms gateway.
The error:
//Adapter.java
public class Adapter extends RecyclerView.Adapter<Adapter.Viewholder> {
String contactdonor;
private static final String URL = "http://Lifetimesms.com/plain?username=opvg&password=mypassword&to=03365297078&from=ComapnyName&message=uyy kugtyf rtd ydrtjyty tku.";
private ArrayList<UserInformation> list;
private Context ctx;
public Adapter(ArrayList<UserInformation> list, Context ctx) {
this.list = list;
this.ctx = ctx;
}

}
