This Flipper plugin is an app introspection plugin focus on Android Sdk mains objects and their life cycle.

It enable to see the "big internal picture" of your running app in a side tool. Meaning that :

• trough running the app as a user
• you can kee an eye on internals as a developer

The plugin is under development Name is not sealed (ideas are welcome)

You can :

• see the app object structure
• application
• activities
• fragments
• viewModels (with reflexion)
• liveDatas (with reflexion)
• jobs (not yet available)
• services (not yet available)
• trash (objects destroyed)
• backstack (legacy)
• backstack (jetpack navigation)

The object structure is view as a tree, where each instance of an object has is dedicated object category.

• HomeFragment parent is fragments

• HomeFragment children are running instances of HomeFragment

• filter objects in the tree (not yet available)

You can :

• see the object lifeCycle events for

  • activities
  • fragments

• filter those event categories

• created/destroyed

• started, stopped

• paused, resumed

• attached/ detached

• ViewCreated

• SaveInstanceState

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {
        implementation 'com.github.afaucogney:flipper-backstack:b1329a419a'
}

Install the plgin in Flipper, it is called lifecycle Npm page

• identify runtime object instances and structure
• identify leaks (remaining objects)
• identify bug instantiations (recreation Vs preservation)
• understand architecture in a breeze
• see object instantiation in real time
• lifeCycle issues
• backStack issues

• Be able to filter object in structure
• Evaluate saving data in db / shareprefs
• Handle clean versioning / release
• Generate docs
• Embed Desktop Code Source here
• Impl Jobs
• Impl Services
• See bundle / saveinstance state
