* Logs the app ' s Baseline Profile Compilation Status using [ ProfileVerifier ] .

When delivering through Google Play , the baseline profile is compiled during installation .
In this case you will see the correct state logged without any further action necessary .
To verify baseline profile installation locally , you need to manually trigger baseline
profile installation .
For immediate compilation , call :
` adb shell cmd package compile - f - m speed - profile com . example . macrobenchmark . target `
You can also trigger background optimizations :
` adb shell pm bg - dexopt - job `
Both jobs run asynchronously and might take some time complete .
To see quick turnaround of the ProfileVerifier , we recommend using ` speed - profile ` .
If you don ' t do either of these steps , you might only see the profile status reported as
" enqueued for compilation " when running the sample locally .

val status = ProfileVerifier . getCompilationStatusAsync ( ) . await ( )
