Android - Java vs C++

Performance is becoming an even more important factor when writing code for mobile devices, even as they get faster every year.

Writing code in C or C++ has always been preferred when writing high performance code that performs heavy work, but it has not been a first class citizen on Android which is written mainly in Java. However, in the Android framework Google has chosen to write several smaller methods (such as matrix operations) in native code, even though the performance benefits are not obvious.

In this thesis work you will analyze the overhead of making a native call from Java in Android, measure how much the performance differs between Java and C/C++, as well as how much additional work it requires on the developer side to write native code compared to Java. You will do detailed analysis of the generated byte code (DEX format) and compiled native code for different parts of an app, and attempt to identify if and when it's worthwhile to move parts to native code.

This thesis work may suit you if:

• You are interested in performance and low level programming.
• You are familiar with both Java and C++.
• You've previously decompiled applications to satisfy your curiosity.
• You are fascinated that small changes can result in huge performance gains.

For this position; understanding spoken Swedish is a requirement, speaking Swedish is a plus. Android experience is not required but is beneficial.
