In this article, the editor introduces in detail "Android app startup node and reporting startup method". The content is detailed, the steps are clear, and the details are handled properly. I hope this "Android app startup node and reporting startup method" article can help you solve your doubts.

Key nodes started by app

The startup libraries in content provider and Androidx are often used to initialize libraries, so what is the order in which the key methods of app startup are executed? How do I control the startup order of my library?

Refer to this article: Android multiple ContentProvider initialization order

The essence is in this picture:

Answer the above question: how do I control the startup order of my library?

It is recommended to use contentprovider and set initOrder.

Startup is not recommended because it can only be controlled by dependency in the dependices () callback. It is strongly dependent and inflexible.

How to calculate the startup time solution 1: refer to firebase:

From the first contentProvider's attachInfo to the first page's onReusme:

App-start-foreground-background-traces: https://firebase.google.com/docs/perf-mon/app-start-foreground-background-traces?authuser=0&platform=android

App start trace

This trace measures the time between when the user opens the app and when the app is responsive. In the console, the trace's name is _ app_start. The collected metric for this trace is "duration".

Starts when the app's FirebasePerfProvider ContentProvider completes its onCreate method.

Stops when the first activity's onResume () method is called.

Note that if the app was not cold-started by an activity (for example, by a service or broadcast receiver), no trace is generated.

Take a look at the configuration of FirebasePerfProvider:

InitOrder= 101is basically the largest. None of the other Provider in the project is configured with initOrder.

You can print / report a similar trace by yourself.

Then you can see the log output of logcat and the statistics of trace platform.

Option 2: ams

Adb command:

Adb shell am start-W package name / entry activity full class name

The log is output on the console:

The time here will be a little less than that of option 1.
