Tracing Action Response Times!
This library is not stable for usage beyond Square, the APIs and internals might change anytime.
Tart... ?
Add the tart
dependency to your library or app's build.gradle
file:
dependencies {
implementation 'com.squareup.tart:tart:0.1'
}
Then add a new AppLaunch.onAppLaunchListeners
. See AppLaunch
javadoc for details.
import android.app.Application
import tart.AppLaunch
import tart.PreLaunchState
class ExampleApplication : Application() {
override fun onCreate() {
super.onCreate()
AppLaunch.onAppLaunchListeners += { appLaunch ->
val startType = when (appLaunch.preLaunchState) {
NO_PROCESS -> "cold start"
NO_PROCESS_FIRST_LAUNCH_AFTER_INSTALL -> "cold start"
NO_PROCESS_FIRST_LAUNCH_AFTER_UPGRADE -> "cold start"
NO_PROCESS_FIRST_LAUNCH_AFTER_CLEAR_DATA -> "cold start"
PROCESS_WAS_LAUNCHING_IN_BACKGROUND -> "warm start"
NO_ACTIVITY_NO_SAVED_STATE -> "warm start"
NO_ACTIVITY_BUT_SAVED_STATE -> "warm start"
ACTIVITY_WAS_STOPPED -> "hot start"
}
val durationMillis = appLaunch.duration.uptime(MILLISECONDS)
println("$startType launch: $durationMillis ms")
}
}
}
