Advertisers using Twitter?s MoPub mobile ad exchange can now customize their software-development kits to account for only the ad formats they wish to use.
Elena Elfimova, who works on exchange product marketing for Twitter, announced in a blog post Thursday that Twitter introduced a modular SDK for iOS and Android applications, allowing publishers to focus on only their desired ad formats and minimizing the space used by the SDK, pointing out that apps on both platforms have size limits of 100 megabytes. She wrote:

Think you might want to try a new format later on" With MoPub, you have the freedom to update your formats at any time, without any commitment to the formats that you’ve previously chosen. She also described how the modular SDK for MoPub works:
The new modular structure allows you to selectively embed part of the SDK in your application, resulting in savings of up to 60 percent of disk space on Android, up to 35 percent on iOS and a reduction in total app size.
The image below illustrates an example of an Android publisher who uses banner, full-screen/video, and rewarded video ads in their app. With the modular SDK, they can include the code for only the formats they?re using, trimming their MoPub SDK size down to 40 percent of the complete SDK.
