Great library, works well in debug.
However, after I exported a signed application package, it crashes every time I try to fire up a chart. Just, puff!!!
I'm using sdk 19 and targeting 16 min.
Does AChartEngine have any special ProGuard settings?
Any suggestions?
Here is part of the logcat (thanks to keshav):

I've been running a Ktor server application locally and deploying to Heroku for the last several months without any issues. However after deploying the latest version, I started to see the following error on any POST requests trying to process the request body on Heroku:

Thinking that there might be something unexpected with the request body, I first tried changing call.receive<MyObject>() to call.receiveOrNull<MyObject>(), yet the issue persisted.
I got tipped off that this might be a JVM mismatch issues, so I checked Heroku's Java documentation and learned that the default JVM is 1.8. I then ran my application locally with Java 1.8 and was able to re-create the same behavior.
After changing the target JVM on Heroku for my application to version 11, this has apparently fixed the problem. While I did recently add the Ktor Authentication "feature", I can't see any other changes that might have caused this. I tried to find in the Ktor documentation what the minimum required JVM target is and was not able to find it. It's great that it's working again, but I'd like to have more confidence moving forward.
In order to ensure proper execution of the server and to avoid this kind of issue in the future, I'd like to ask what the supported JVM target(s) are for Ktor Server (and if possible, have this added to the Ktor documentation).
I solved by upgrding to ktor_version:1.6.7.

I have no luck finding this issue in StackOverflow, but I have found it in Google Issue Tracker, but with no response. So I created submitted an issue to Google with more information. https://issuetracker.google.com/issues/176085956
Has anyone encounter this issue and was able to solve it.
My working environment is:
Mac OS 10.15.7
Android Studio 4.0.1
Samsung A70
Android version 10
While this is not documented formally on developer.android forum, looks like AndroidKeyStore access is restricted for instant apps. I came across this link https://www.reddit.com/r/androiddev/comments/7a4tdw/why_no_hardware_backed_keystore_in_instant_apps/
This is quite strange that keystore is restricted and no android documentation explains it. I am not sure on an alternative to accessing KeyStore as we have lot of dependency on keystore for our regular app (non instant) and I can't think of a better option. Looking forward for suggestions !

Does anybody know how to solve it?
Errors of this kind typically mean the code you are attempting for run is for a different version of Java than you are trying to run.
Stardog requires Java 8:
Stardog runs on Java 8
So please ensure you are running it under Java 8, providing the output of java -version in your environment as part of your question would be helpful in determining if this is your problem.

The IDE doesn't boot up afterwards. It always worked flawlessly before but recently I have been getting this same error when trying to compile a Java project with IDEA version 14.5. After a clean installation of 15.0.1 it still doesn't work. It becomes quite obvious that the problem must be due to something I installed in the meantime but what could affect IntelliJ IDEA in such a way? I'm on Windows 10 and using AVAST!. I tried disabling my Antivirus and Firewall but it didn't help. I also submitted a bug report. Eclipse still runs and compiles Java code just fine.
It does seem to be AVAST! related. Maybe try to reinstall or deinstall it?
https://youtrack.jetbrains.com/issue/IDEA-146929
https://bugs.mojang.com/browse/MC-34749
I was having the same issue. Disable your firewall or check your security settings.
your firewall and antivirus program is blocking the android studio so remove antivirus program or add android studio.exe in allowed list this helped me
The solution is really easy. You just need to delete all .androidstudio* folders from appdata folder on your PC. Note that i don't know if this folder contains anything important.
Yeah it is a problem with Avast security! I was using studio fine until one day my computer kept slowing down. I read that having 2 anti virus softwares can slow down your pc so i tried installing avast and just stick with Windows Defender. Avast cannot properly uninstall now the software is corrupted or something cause it wont start up. If you can get rid of Avast you will be good to go.
Restarting Windows works for me. But I think it is related to the firewall.
It happened after I closed a Windows Firewall dialogue asking me if another app (Everything.exe) can access the network (workplace, private or public) without response. After I restarted Windows, IntelliJ could launch normally.
when I am starting glass fish server through command prompt I am getting an
error. I am using jdk 1.5 and jdk1.6 also. Due to java version am I getting that error or any other reason.
I am using two tomcat server also that port no is 8080 and 8081.
For glass fish-domain purpose I am using 4545 port number.
Error starting domain mydomain1.
The server exited prematurely with exit code 1.
Before it died, it produced the following output:

This is the important bit.
java.lang.UnsupportedClassVersionError: Bad version number in .class file
It means that the class loader does not understand the version number of one of the ".class" files that it is trying to load.
The most likely explanation is that you are trying to load classes that have been compiled on a Java 7 development platform on an earlier (e.g. Java 5 or Java 6) JRE / JVM installation. You either need to upgrade your execution platform to Java 7 (best option), or downgrade your development platform to Java 5 or Java 6 (or whatever you are using).
Note that both Java 5 and Java 6 have reached "end of life", and there will not be any more patch releases available ... unless you take out an Oracle Java support contract.
