Performance V2

Performance V2 contains a set of features that enrich performance instrumentation. It tightly integrates with the Mobile Vitals Insights module, enabling App Start and Frames Delay reporting.

Since version 8 of the SDK, Performance V2 is generally available and enabled by default. In versions 7.4.0..<8.0.0, this feature is available as experimental and you need to opt in to use it:

Enabling Performance V2

import io.sentry.android.core.SentryAndroid;

SentryAndroid.init(this, options -> {
  options.setEnablePerformanceV2(true);
});

App Start

Besides enabling Performance V2, this feature requires the Sentry Android Gradle Plugin (version 4.2.0 or above) to be applied to your app module.

Once enabled, your App Start transaction will show a detailed span breakdown of various components:

• process.load: The process initialization time
• contentprovider.load: ContentProvider.onCreate() execution time
• application.load: Application.onCreate() execution time
• activity.load: The execution time of your Activity lifecycle prior to the first frame being drawn

Frames Delay

Frames Delay is the user-perceived delayed duration of rendered frames. The Android SDK automatically attaches this information to every span, giving useful insights and showcasing which spans correlate the most to an impaired user experience.
