[ANR] Input dispatching timed out. Discuss thread (SOLVED)

Insality · February 17, 2019, 3:22pm

Thanks for advices, some of them I will try soon.

Some time ago I already reduced memory allocation of every frame, and it is possible, what a little reduced ANR percentage, but not sure. I can dig into this more. I try to share info with GC on android later

ProFI nice instrument too, already profiling with this.
Digging into I/O operations show us the json bug, but for now seems problem is not in I/O operations.

I took a look at some other games (King) and see numbers from 0.03% up to around 1%, this with a mix of engines. I have one Defold game at 0.23% without much focus spent specifically on reducing ANRs on that title.

@AGulev what kind of numbers do you have on the Solitaire game of yours? And maybe also Bring Me Cakes?

AGulev · February 17, 2019, 4:07pm

Current ANR rate for Solitaire game:

Bring Me Cakes:

Solitaire:

britzl · February 17, 2019, 9:08pm

Ok, so 0.04% for Classic Solitaire is proof that it is not the Defold engine itself that is at fault, at least not when used like in Classic Solitaire.

Bring Me Cakes shows a higher percentage (0.29%), is that with DefUnityAds or any other larger native extensions?

So, the question is what the difference is between Family Age and Solitaire (and to some extent Bring Me Cakes)?

Are you using any native extensions? If so, which ones?
Are you using local push notifications?
Are you stripping parts of the engine using an app manifest? If so, what are you removing?
That memory investigation I mentioned before would be interesting to know more about.

As soon as we get a little more data we will as well join the discussion as we always have suffered from a bunch of ANR’s. Most of them immediately at the loading screen. We are releasing a new version today and will gather info.

AGulev · February 18, 2019, 7:17am

As I remember, most of ANR on Blastlands load was caused by this issue.

AGulev · February 18, 2019, 8:09am

Both projects without NE,
BMC:

excludeLibs: [“record”,“vpx”,“profilerext”,“engine”]
excludeSymbols: [“ProfilerExt”]
libs: [“engine_release”,“record_null”]

Solitaire:

excludeLibs:[“physics”,“LinearMath”,“BulletDynamics”,“BulletCollision”,“Box2D”,“record”,“vpx”,“profilerext”,“facebookext”]
excludeJars: ["(.)/facebooksdk.jar","(.)/facebook_android.jar"]
excludeSymbols: [“ProfilerExt”,“FacebookExt”]
libs: [“physics_null”,“record_null”]

britzl · February 18, 2019, 8:43am

Any ideas why BMC would show higher numbers? More on_input code? Heavy code in update(), garbage collection, HTTP requests?

AGulev · February 18, 2019, 8:48am

No Idea right now, but I’ll continue my investigation. I wanna release the new version of solitaire with some fixes and with new Defold (waiting for new version now).

Dragosha · March 21, 2019, 8:42am

1.08% is current ANR rate after added “exit from app” button:

britzl · March 21, 2019, 10:20am

Huh, so ANRs have gone up and not down? This is opposite of what we have seen for other projects.

You should be using sys.exit() (or the old “exit” message) and never use os.exit(). Can you please confirm this?

Potential known causes of ANRs:

Engine
- HTTP requests on crappy connections. This is caused by getaddrinfo being synchronous. We are working on this issue in our current sprint.
- Local notifications. I see this issue in some games, but it is not very frequent. Do you have any ANRs with com.defold.push.LocalNotificationReceiver
User code
- Doing too much work in a single frame. Examples:
  - Calculations in Lua code that take too long to execute.
  - Doing a lot of I/O operations (I/O operations are typically quite slow on mobile devices).
  - Using factory.create() or collectionfactory.create() on a factory component where Load Dynamically is checked and you haven’t called (collection)factory.load() prior to instantiating the first instance.
Using os.exit() instead of sys.exit()

If anyone has more ANR causes, please share them here!

Dragosha · March 21, 2019, 10:09am

I’m using

msg.post("@system:", "exit", {code = 0})

Full list of registered ANR:

Insality · March 27, 2019, 9:05am

So, I removed exit button on android too and have next results:

With exit button:

Without exit button:

Just for statistics. Exit was with msg too

timer.delay(0.01, false, function()
    msg.post("@system:", "exit", {code = 0})
end)

AGulev · March 27, 2019, 9:16am

Thanks for sharing your statistics!
We think the reason for ANR is this known issue:

Exit from the application one of the most simple way to reproduce this ANR but not the only one.

@jhonny.goransson is working on this issue.

britzl · March 27, 2019, 9:33am

Ys, it’s actively being worked on. It will unfortunately not get finished in time for the release on Monday. It will be included in 1.2.151 instead.

AGulev · May 13, 2019, 2:23pm

It should work fine in 1.2.153 (DEF-3815)

AGulev · May 21, 2019, 6:16am

It seems like in my game count of ANR impacted session reduced 3 times.

Dragosha · June 7, 2019, 7:47am

My current ANR stats (67 build with 1.2.154):
