My firebase console dose not show any data if I go to rules then also it is not showing rules also it is just showing unable to show rules what should I do?

it might seem ridiculous but I have tried to log out and log in but it didn't help so i changed the web browser and it worked

I had the same problem. It was the Ads blocker. Just I disabled it and data showed up.
Be careful of these sneaky extensions.
Hope it helps others.

just goto the RULES option given beside the data in Firebase and change the read,write from false to true and then click simulator and publish it.

I have experienced this problem and try this.
Log out of your Google account.
Close every instance of the browser.
Restart your laptop.
Log into the console.
This has helped me numerous times and it might work for you too.

I have a discord bot developed in Java using the latest version of JDA (4.2.0_168).
I have a few events in my bot and only one works.
The GuildMessageReceivedEvent works but other events like GuildMemberJoinEvent,GuildMemberRemoveEvent and GuildMessageReactionRemoveEvent don't work.
The problem is before I updated the version everything was working.
I didn't change anything but the GuildMemberRemoveEvent in the code so I have no idea what to do. I tried to read the docs but nothing is there.
First of all that's not the latest version of JDA. It currently is 4.2.0_212 and you can find the latest on Jenkins any time.
You didn't mention anything about the intents you use so I'll go off on a tangent and assume you don't use intents properly. In order for these events to work you need to enable the GatewayIntent.GUILD_MEMBERS. This is explained in the requirements section of the event documentation.
Use enableIntents(GatewayIntent.GUILD_MEMBERS) on your JDABuilder or DefaultShardManagerBuilder. This will allow you to use these events.
I recommend reading the troubleshooting guide if you experience any other issues.

This is a problem I'd like to share with everyone. Also - I have resolved it and it was a pretty interesting problem.
When I received my laptop from repair I had my OS reinstalled. Everything (I mean whole configuration and programming environment) I had to do once more time from scratch.
It took some time, but the next day I was able to return to my work.
Problems started when I tried to run my Java - Spring App. I could run it, but immediately I was facing an error. Within the console, I have read that it was called a broken pipe error.
The solution for this error was to rename the account name in the registry. My account name was using special characters (f.e. like Ü).
I have created a second user with the role of admin. Later I have used win + r, typed regedit, and fired it.
When the Registry Editor has opened, I've entered HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and in there I've found an account of mine. After that, I have changed ProfileImagePath for the desired name.
In the end, I have changed the name of the folder %SystemDrive%\Documents and Settings<Your_Name_To_Change> for the same I have used in the registry. It has solved my problem with broken pipe error.

In a fresh AS project we have error. in our proxy settings we have error too. see the screenshot below:
How can we solve error?
UPDATE:
When we use auto detect, after click to try sync, below window opened:
Can you try use IP address (of fodev.org? are you sure this is correct?) in this case see whether it works?
You can tick the auto-detect proxy settings see whether it helps or not.
fodev.org:8118 seems to be accessible, at least from here. Maybe try to use another proxy, or find a VPN provider, that offers endpoints in your country of residence. As a paying customer you could bug them, when it doesn't work - not so with some free of charge service alike: https://github.com/freedomofdevelopers/fod

I created an app game that runs perfectly on the eclipse emulator. However, when my friends download it in the Google Play Store it crashes on start up. I have attached the crash report from my Google Developer Dashboard, it says the crash is caused by java.lang.ClassNotFoundException but I can't figure out how to fix this. Can you guys please help me? I've been struggling with this for a few days.

One suggestion I have - please check if user sometimes earlier already installed and tested older version of the game, and possibly old corrupted data stay at the device memory. In this case un-installing the app thru app manager, and cleaning-up the related data may help. Good luck!
