Nanoscope is an extremely accurate Android method tracing tool from Uber, implemented partly as a fork of AOSP to achieve ~20 nanoseconds of overhead per method call. It is driven by a command-line client that launches a custom emulator, flashes supported devices with the Nanoscope OS, and starts/stops tracing sessions.
Use cases
- trace android method calls with nanosecond-level accuracy
- profile android app performance with minimal overhead
- launch an emulator with built-in method tracing support
- flash a nexus 6p with a custom tracing os
- capture cpu utilization and page fault data for app threads
- find performance bottlenecks in android applications
When to choose
- you need extremely low-overhead, high-accuracy method tracing on android
- you are willing to use a custom emulator or flash a supported device
- you are debugging performance issues in android apps on macOS
When to avoid
- you need to profile on arbitrary or newer android devices (only Nexus 6P is supported for flashing)
- you cannot replace the device OS or rely on a special emulator
- you need an actively maintained tool (last release was 2020)
- you are not on macOS for the emulator workflow
