How many lines of code are in Android 16?

2025-06-12

Android 16 just released, and with it the code size grew again (+50 mil. LoC since Android 14). But you probably came here because you searched for how much code runs on your device. The rough answer is 92 million for explanations why putting a number on this is misleading read my last post on that matter. If you want to explore explore the data yourself there are two more details below. As always the raw data and source code is here.

Quick facts

There are over 250 million source code lines contributing to android.
Roughly 92 million lines of code run on the average device.
83 million lines of comments and documentation tell the developers what the code does.- 8.8% lines are empty.

Doughnut chart

This time I included this nice interactive doughnut chart of the programming languages used (unfortunately requires JavaScript).
