Correcting the memory safety bugs in the Android ecosystem is a matter of great difficulty. Google has recently announced that the open-source version of Android OS will be having the support of Rust to square off with exposed vulnerabilities.

Under the realm of the Hybrid app development process, Android OS is exposed to more vulnerability during the development stage. It has a lot of moving parts in the ecosystem and OS itself. It is essential to correct the code to maintain the security, stability, and quality of each release. It is difficult to ascertain the fixed memory safety bugs in C and C++ programming languages. Despite many efforts put in to detect, fix, and mitigate this class of bugs, it still appears as the top contributor representing 70% of Android’s high-security vulnerabilities.

Thus, to improve the detection of memory bugs, Google announced the adoption of memory-safe languages to be the cost-effective solution to get rid of the bugs. In addition with readily available memory-safe languages like Kotlin and Java, one more addition is Rust that helps in the bug-free Flutter app development process.

C and C++ Limitations

When it comes to the lower levels of Android OS system programming, it requires the support of C and C++. These languages provide developers the control and predictability to access low-level system resources, and hardware. Still, these have their own set of limitations.

Here are Few Limitations of these Lower-Level Languages

1. C and C++ fail to provide any protection against memory safety. These are often exposed to bugs and security vulnerabilities. Under this, developers need to manage the memory languages for a lifetime, especially during complex and multi-threaded codebases.

2. The languages contain tens of millions of code under the Android ecosystem. Thus, fail to address incorrect sources of code.

3. The lack of memory safety restrictions allows developers to rely on tightly constrained and unprivileged sandboxes. However, sandboxes are expensive resources and fail to provide the required code elimination advantage to Android OS and further allow attackers to chain multiple vulnerabilities.

Introduction of Rust in Android Ecosystem

Rust is the ultimate solution to bring much-needed safety to memory and results in the elimination of all the bugs. It uses the combination of compile-time check that enforces object lifetime/ownership. It also runtime checks to ensure the fact that memory accesses are valid or not. Rust is also efficient in reducing the dependency on Sandboxes and allows developers to have more overhead time to introduce new features that are safe and light in weight.

Top Benefits of Using Rust

A. It is not a feasible option to let Rust being exposed to all Android OS overnight. This is because Android’s memory bugs occur in a new or recently modified code. Also, 50% of the codes are less than a year old. So, Rust is best to deal with memory safety vulnerabilities on the newest developments rather than focusing on already matured C and C++ code.

B. Rust is beneficial to put a limit in preventing bugs rather than just heavily detecting the bugs and result in improved performance.

C. It offers additional benefits like data concurrency, memory safety, more expensive type systems, safer integer handling, error handling in standard libraries, and more.

Wrapping Up

According to Google, it has been adding Rust to the Android open source project for the last 18 months. But adding any new language to Android OS demands tool chains, dependences, and undertaking to maintain and test infrastructures. You can hire Android app developers who are trained and know how to introduce Rust in the app development framework.

Rely on the professional expertise of Android Developer which is a leading Android App development company. Professional developers of the organization will help to develop result-oriented applications and adding the virtues of Rust to ensure maximum memory safety.
