ReleaseExampleApplication.kt

TLDR

This file contains the ReleaseExampleApplication class which extends the ExampleApplication class. It initializes and configures the HeapAnalysisClient and sets up triggers for background and screen off heap analysis.

Classes

ReleaseExampleApplication

This class extends the ExampleApplication and overrides the onCreate method. In the onCreate method, it performs the following tasks:

• Installs the LogcatSharkLog for debugging purposes in release builds.
• Creates an instance of HeapAnalysisClient.
• Creates a single-threaded executor for running heap analysis tasks.
• Deletes any existing heap dump files.
• Sets up a callback function for receiving analysis results.
• Starts the BackgroundTrigger and ScreenOffTrigger for initiating heap analysis.
