[idosun]

See docs: https://docs.sentry.io/platforms/android/profiling/#app-start-profiling

<application>
    <meta-data android:name="io.sentry.dsn" android:value="" />
    <meta-data android:name="io.sentry.traces.sample-rate" android:value="1.0" />
    <meta-data android:name="io.sentry.traces.profiling.sample-rate" android:value="1.0" />
    **<meta-data android:name="io.sentry.traces.profiling.enable-app-start" android:value="true" />**
</application>

Note: App Start Profiling doesn't appear the first time the app starts.

Expected behavior: https://demo.sentry.io/profiling/profile/android/ee35c740cc8e40eab88ddc2a87ca9639/flamegraph/?colorCoding=by+system+vs+application+frame&fov=0%2C0%2C1337161856%2C7&query=&sorting=call+order&tid=8957&view=top+down

Expecting profiles like com.example.vu.android.ThirdPartyContentProvider.onCreate()

App Start Profiling has been enabled for MyApplication.java

[sdzhong]

Is it possible to send the options to enable app start profiling to the SDK in the app. Or another content provider to start before the others to mock the options used by the SDK? @stefanosiano

should be fixed by #136
