I am relatively new to working with Nao Robots. As part of many guthub repositories, simulator sdk packages are needed for code to work. I am unable to find those. If they are deprecated, what's the alternative?
You do not need a Simulator and that Simulator SDK to work with a robot.
If you need a complete simulator environment running NAOqi, try Webots. If you use ROS, Gazebo should work too.

We are getting this message in android store. Fixing it is not mandatory for releasing but its a security risk.
Please help,how to update webrtc version.
Google stopped providing Android library directly for webrtc, but the source is open and the link you shared has instructions on how to build the Android library from source.
It is a long process, but if webrtc is essential for your app, you have to spend some time to set this up.
If you need a temporary fix, I found that someone does this in their github repo often, and you can use the Android library there directly
https://github.com/dbrgn/webrtc-android
Note that, the author of this library itself recommends to build the library from the source directly.

Good evening everyone, I have only been dealing with Java and Android Studio for a few months, can someone help me to solve this error? It occurs every time the emulator starts. Thank you
Emulator: Started GRPC server at 127.0.0.1:8554
Emulator: emulator: WARNING: EmulatorService.cpp:448: Cannot find certfile: C:\Users\Sawye.android\emulator-grpc.cer security will be disabled.
Invalidate and Restart option in Android Studio, followed by gradle clean, and manually uninstalling the application from the emulator finally worked for me. Individually, they didn't for whatever reason.
I tried several other options mentioned without any luck. The file it mentioned "emulator-grpc.cer" still doesnt exist anywhere. There is a keystore in that folder called debug.keystore which isn't altered after fixing it, so I'm guessing that error is just misleading about the real problem, whatever it is. Anyway, thought I'd share what worked for me since I searched everywhere for it and didn't find it.
A quick fix:
From the main navbar menu
Tools > Android > SDK Manager > Android SDK > SDK Tools
You'll then see the screen below where you can select '- Android Emulator Hypervisor Driver for AMD Processors (installer) version 1.3.0'
I am not sure what the actual root cause of the issue is, but this patched the issue for me and may help other people.
Here my scenario: I closed the emulator with force quit. After restarting emulator, I always got this error.
Fix: I opened the AVD Manager in Android Studio by selecting Tools > AVD Manager menu. In the opened popup, I chose Wipe Data option as can be seen below image. After that, I restarted emulator and it worked !!!
Your emulator is out of date, please update by launching Android Studio:
Start Android Studio
Select menu "Tools > Android > SDK Manager"
Click "SDK Tools" tab
Check "Android Emulator" checkbox
Click "OK"
Got the same issue, I restarted the computer and then runned again the emulator and it worked. Important! you have to run the app, not debug it. You can use debug after the app is installed again in the emulator
Unless it's preventing your app from running in the emulator, or preventing the emulator from running at all, I wouldn't worry about it. It's something new that Google put into the emulator so it now checks for that file. I looked at an installation which did not have the updates and the cert file was missing there as well, and it ran just fine with no error. I'm not sure what Google is doing, but I know that this wasn't thought through all the way based on the number of people who have been having problems with this.
I was also getting the same error. The above answers didn't fix my issue. I tried a lot of things, then finally when I uninstalled Intel x86 Emulator Accelerator (HAXM installer) from-
Tools > Android > SDK Manager > Android SDK > SDK Tools.
Then I reinstalled Intel x86 Emulator Accelerator (HAXM installer). This fixed my issue and I was able to run my emulator again. Hope it helps!
I have tried all the strange answers above nothing solved the issue. So searched in google's issue tracker, I found someone posted an Issue about it, and here is what the team wrote in response:
Hi, this warning is benign. We'll remove it in a future update.
So as google said: that warning is nothing to be worried, not harmful, and will be removed!
Update:
Issue was now indeed fixed with latest Release Update for the Canary Dev Channel:
Removed prints about certs and GRPC on startup.
You need to add credentials for your application in console.developers.google.com i.e. credentials, clik Api Key 1 and than ADD AN ITEM in Restrict usage to your Android apps.
I'm having some trouble integrating my app with the parse4cn1 lib. I followed the tutorial published on this link and the app registers normally on the Parse Server as an installation but when I try to send a push to Android devices they simply aren't being sent.
I haven't tried on iOS yet, since I figured I'd start with Android, and I'm working with a new GUI Builder app if maybe that affects something for any reason.
Thanks for your help.
Ok, I have found the problem, it was related to parse not the parse4cn1 lib. I'm actually new with parse and backend in general, I wasn't aware I had to run the pm2 restart command after modifying the cloud code.
It's working now, thanks!
I just learned about the Intel XDK at Indiecade today, and I couldn't wait to get home to try a port of one of my Construct 2 games. The game ended up working perfectly, aside from the fact that it has no sound when played on my Galaxy S5. The Intel XDK Emulator plays the game with sound, but for some reason it doesn't work on my phone. My volume is all the way up. Are there any tips when importing C2 games with the Intel kit to make sure the sound is preserved?
One thing I might add is when I run the app, it gives me an error message as though I am trying to run it locally in my computer. The actual message:
Alert: Exported games won't work until you upload them. (When running on the file:/// protocol, browsers block many features from working for security reasons.)
And then it auto-jumps to:
Application Error: The connection to the server was unsuccessful. (file:///android_asset/www/index.html)
... as a matter of fact it stopped working altogether after the two error messages while I was typing this question.
Edit: OK... so I exported it within the XDK as Crosswalk rather than simply Android, and the music now works. However, the first error message I mentioned before still shows up. I won't want this on all of my apps. Any way to get rid of it?
OK so this is what I did wrong: When I exported through Construct 2, I did what I always do and exported as a web app. What I should've done is export it as an Android app. I seriously don't know why I didn't try this first but after exporting as Android and then using the Intel XDK to port it with Crosswalk, everything is peachy.
I found my answer here: https://www.scirra.com/blog/133/introducing-crosswalk-the-new-way-to-publish-to-android
I'm glad you found the answer here; I knew there would be a way :)
Just wanted to chip in as a follow-up, there is a webinar tomorrow for a much more in-depth tour of the XDK and its features - including crosswalk - than I was able to provide at IndieCade. Let me know if it works out for you!
Thanks,
Brad

This happens if you export as a normal html5 and not as Cordova app.
I had the same problem. I'm calling other HTML offline and solved the problem with this post:
https://software.intel.com/en-us/xdk/docs/adding-third-party-plugins-to-your-xdk-cordova-app
How Do I Reference cordova.js Script from My Project index.html File
To enable the use of Cordova plugins in an HTML5+Cordova project type, reference the cordova.js script file exactly once in your index.html file:
If your project contains more than one HTML file (or page) that will use Cordova APIs, you must include a reference to the cordova.js script file in each of those HTML files. It is highly recommended that you limit yourself to building single-page apps (SPAs) when creating Cordova applications. See this Cordova Best Practices article for more details. Also, note that the cordova.js file is a "phantom" file; it is not present in your project directory, but is added by the Cordova build system when your application is built (it is customized for your app as part of the build process).
I don't trust the native Sqlite3 in MonoTouch anymore. I keep getting random crashes and although I cannot prove it, I claim that it is not my fault.
To verify this I would like to use a managed replacement of Sqlite3.
Is there a project that is syntax compatible with the native version? And more important: does somebody have experience with it?
Look at the Xamarin cross-platform MWC sample.
While it use the native libsqlite on iOS and Android versions it does use a fully managed port of SQLite for the Windows phone version (where SQLite is not available and where it's not possible to add native code).
However that won't tell you what's wrong with your application. If you're using other native libraries in your project I suggest you to remove them (one by one) and try to duplicate the sqlite crash again.
