OSV Demo for new Android version

Scope for Android 15

1. ApplicationStartInfo

https://github.com/ellisonchan/AndroidOSVDemo/tree/main/app/src/main/java/com/ellison/osvdemo/appStart/AppStartActivity.kt

Output following info contents according to ApplicationStartInfo API.

 03-30 20:46:27.461  4499  4499 D AppStart: OSVApplication#onCreate()
 03-30 20:46:27.477  4499  4499 D AppStart: Original applicationStartInfo list:

 ​
 03-30 20:46:27.638  4499  4499 D AppStart: AppStartActivity#onCreate()
 03-30 20:46:27.961  4499  4563 D AppStart: ApplicationStartInfo{intent:Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.ellison.demo/.appStart.AppStartActivity } launchMode:0 packageUid:10197 realUid:10197 pid:0 processName:com.ellison.demo reason:6  startType:1 startupState:2 startupTimestamps:{0=56169205650, 3=56491075233} wasForceStopped:false}

2. ProfilingManager

https://github.com/ellisonchan/AndroidOSVDemo/tree/main/app/src/main/java/com/ellison/osvdemo/profiling/ProfilingActivity.kt

Request dumping java heap from codes by ProfilingManager.

class ProfilingActivity : AppCompatActivity() {
    private val singleThreadExecutor = Executors.newSingleThreadExecutor()

    private val profilingResultConsumer = Consumer<ProfilingResult> {
        Log.d(TAG_PROFILING, "accept profilingResult:${it.printProfilingResult()}")
    }

    private val profilingManager by lazy {
        getSystemService(ProfilingManager::class.java)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        ...
        binding.dump.setOnClickListener {
            Log.d(TAG_PROFILING, "button dump tapped")

            profilingManager.registerForAllProfilingResults(
                singleThreadExecutor,
                profilingResultConsumer
            )
        }

        binding.request.setOnClickListener {
            Log.d(TAG_PROFILING, "button request tapped")

            profilingManager.requestProfiling(
                // ProfilingManager.PROFILING_TYPE_SYSTEM_TRACE,
                // ProfilingManager.PROFILING_TYPE_JAVA_HEAP_DUMP,
                ProfilingManager.PROFILING_TYPE_STACK_SAMPLING,
                // ProfilingManager.PROFILING_TYPE_HEAP_PROFILE,
                null,
                // null,
                "TEST_FOR_PROFILING_MANAGER",
                null,
                singleThreadExecutor,
                profilingResultConsumer
            )
        }
        ...
    }
}

And output ProfilingResult as below:

04-21 19:37:32.220  7184  7270 D Profiling: accept profilingResult:ProfilingResult{errorCode:0 errorMessage:null resultFilePath:/data/user/0/com.ellison.osvdemo/files/profiling/profile_testforprofilingmana_2024-04-21-19-37-26.perfetto-java-heap-dump tag:TEST_FOR_PROFILING_MANAGER}
