How to Find memory leaks from native ndk 'C' code in android (latest way)

Question

What is the way to find memory leaks that are in ndk C code in android studio? As every one on google and stackoverflow refer to ddms for memory leaks in ndk C code but ddms is no longer present in android sdk as described in the following link How to Find memory leaks from native code in android

It also does not help as there is no way to run ddms.

I think you need to look at AddressSanitizer and Valgrind tools for getting memory leaks from native ndk C code in android. I am struggling with the same problem here. I was able to run my app using valgrind, but it slows down the application too much. I am currently looking at Address Sanitizer. If you already have the solution can you kindly let me know. — user2284140, Sep 08 '17 at 18:53

Use LeakCanary.

The description on how to implement that in code is well described in Getting started

This library does not tell about memory leak in ndk – Waqas Ahmed Aug 20 '17 at 07:43
You did not mention "Native NDK C code" before editing your post. This is confusing. Before giving any negative vote, know your worth first. – Aveek Aug 22 '17 at 07:09
i have mentioned native code in android and added tags jni and android ndk and also referred a question which is also about ndk – Waqas Ahmed Aug 22 '17 at 07:44
Now i can not revert that voting – Waqas Ahmed Aug 22 '17 at 07:45
I don't want you to do that. – Aveek Aug 22 '17 at 07:48

Setup LeakCanary

Go through the description in Readme to setup.

In your build.gradle:

dependencies { debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5.2' releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.2' }

And initialise it in Application class

LeakCanary.install(this);

Will this library tell about the memory leaks in c code? – Waqas Ahmed Aug 16 '17 at 09:42
u mean ndk?... This library is configured for the app. So where ever a leak happens within the app it will be shown – Nidhin Prathap Aug 16 '17 at 09:43
Yes ndk and i want to detect memory leaks in C code – Waqas Ahmed Aug 16 '17 at 09:43
It should u can refer this Medium Post :- https://medium.com/square-corner-blog/leakcanary-detect-all-memory-leaks-875ff8360745 – Nidhin Prathap Aug 16 '17 at 09:44
There is no description in that library docs that it will catch native ndk memory leaks – Waqas Ahmed Aug 16 '17 at 09:45
Yes but memory leak is within the app no matter its ndk or native.. so the Leak Canary will be able to capture it – Nidhin Prathap Aug 16 '17 at 09:46
