Software Development Kits (SDKs) allow developers to significantly enhance the functionality and performance of their apps, among other benefits, without writing complex code. By importing SDKs, developers can save time and money, access various services and APIs, and achieve compatibility and integration across different platforms, devices and operating systems. When it comes to app monetization, advertisement SDKs are a common way of generating revenue from apps, especially freeware that rely on in-app purchase or subscription.

However, there are also downsides associated with using code from external sources, such as security breaches, data leaks, or malicious attacks and perhaps one of the most effective ways to safeguard an app from such a threat is to perform some type of security audit. Mobile apps though pose a challenge for code review, as they can use webviews to dynamically change their behavior and execute arbitrary code from remote sources, bypassing the security audit of the app.
