java - Android memory: how to inspect memory without using Profiler?

Question

I have a problem of OOM error (OutOfMemory) with my app. It seems that it is due to an object that takes more and more room in memory but I don't manage to find which one.

I would like to use the Android Profiler to find the problem. But I have a real time app that uses a lot the device processor and memory, and when I use the Profiler the app becomes really slow and becomes almost impossible to use (I need to use the app at least 3 minutes at normal speed in order to see the memory growing progressively).

My questions are:

• is there a way to use the Profiler without this slowdown issue?
• if not, are there any other tools or methodology in order to help me finding which object grows in memory?

Thanks !

You can collect your app's heapdump using adb shell

adb shell am dumpheap <PID> <TARGET_FILE>

and view the exported file using android studio profiler

Alternatively, if you know when exactly in your app the OOM happens, you can collect the heapdump using this method Debug.dumpHprofData(String)
