BenchmarkState

class BenchmarkState

Control object for microbenchmarking in Java.

Query a state object with androidx.benchmark.junit4.BenchmarkRule.getState, and use it to measure a block of Java with BenchmarkStateLegacy.keepRunning:

@Rule
public BenchmarkRule benchmarkRule = new BenchmarkRule();

@Test
public void sampleMethod() {
    BenchmarkState state = benchmarkRule.getState();

    int[] src = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
    while (state.keepRunning()) {
        int[] dest = new int[src.length];
        System.arraycopy(src, 0, dest, 0, src.length);
    }
}

Note that BenchmarkState does not give access to Perfetto traces.
