The Jetpack Microbenchmark library lets you benchmark your Android native code—Kotlin or Java—from within Android Studio.

A collection of samples using the performance libraries. You can learn more about Android Performance at https://d.android.com/performance.

The library outputs benchmarking results to both the Android Studio console and a JSON file with more detail.

Android offers two benchmarking libraries and approaches for analyzing and testing different kinds of situations in your app: Macrobenchmark and Microbenchmark.

August 3, 2023 - Jetpack Benchmark Library provides an API for automating Android application code performance measurement.

This library now targets Kotlin 2.0 language level and requires KGP 2.0.0 or newer. (Idb6b5) ... androidx.benchmark:benchmark-*:1.4.0-alpha10 is released.

Benchmarks are standard instrumentation tests. To create a benchmark, use the BenchmarkRule class provided by the library. To benchmark activities, use ActivityScenario or ActivityScenarioRule.

Just use the BenchmarkRule provided by the library: @RunWith(AndroidJUnit4::class) class ViewBenchmark { @get:Rule val benchmarkRule = BenchmarkRule() @Test fun simpleViewInflate() { val context = InstrumentationRegistry .getInstrumentation().targetContext val inflater = LayoutInflater.from(context) val root = FrameLayout(context) benchmarkRule.measure { inflater.inflate(R.layout.test_simple_view, root, false) } } }

@RunWith(AndroidJUnit4ClassRunner::class) class ColdStartupBenchmark { @get:Rule val benchmarkRule = MacrobenchmarkRule() // No ahead-of-time (AOT) compilation at all. Represents performance of a // fresh install on a user's device if you don't enable Baseline Profiles— // generally the worst case performance.

August 11, 2023 - The Macrobenchmark library is specifically created to work seamlessly with Android development. It is capable of benchmarking not only mobile applications but also custom-built Android libraries.

The Jetpack Benchmark Libray is a tool for measuring code performance and is used to remove those common mistakes that we were doing earlier while using Benchmark. This library handles warmup, measure your code performance and output the result ...

October 20, 2023 - All these features are provided by the androidx.benchmark library group. Despite the minor version increment from 1.1.1 to 1.2.0, a lot of new features have been added.

Spanner is a micro benchmarking framework designed to run on Android.

Metrics are displayed directly in Android Studio, and also output for CI usage in a JSON file. While the existing Jetpack Benchmark library allows you to benchmark app code directly in a loop, it's designed around measuring CPU work which is run frequently, and which will hit best-case performance ...

July 27, 2021 - This prevents performance regressions from reaching your users as you add new features and other improvements. We used the new Android Jetpack macrobenchmarking library and showed ways to integrate it with Firebase Test Lab to run benchmarks ...

To run the benchmark, compile and link against the benchmark library (libbenchmark.a/.so).

In this codelab you'll learn to use the macrobenchmark library. You will measure app startup timing, which is a key metric for user engagement, and frame timing, which hints at where jank may occur in your app.

June 18, 2025 - Macrobenchmark is a Jetpack library for testing how your app performs during full user flows, startup, scrolling, transitions, or anything you can simulate through the UI. It runs on real devices or emulators, and it aims to replicate actual ...
