Hi I try to create a simple Map project in Eclipse, when I run my project from Eclipse to device, my map can shown, but when my project was compiled as .apk my map not shown in my Fragment. How to solve my problem?
If you signed your APK with a different keystore you may not have registered both your debug and release keystore on the Google Developer Console.
Check out this link for details on how to add both SHA1 fingerprints (debug and release) so that your API Key works on both.

I'm a beginner in Java. I completed programing for "Triangle Calculator", exported it to JAR with Eclipse, and then turned it to exe with Launch4j. The problem is, the exe only works on my own computer and when I send it to others, Defender anti-virus pops up and also pops up an error. This is the error:
Windows cannot access the specified device, path, or file. You may not
have the appropriate permissions to access the item.
This is a problem on their computer, not yours.
They need to talk to those who set these restrictions and learn how to do it according to their policy.

I cannot create Java record class in IntelliJ, and I could not find the option to enable it.
Is there a way to enable it?
Make sure you have an updated version of the IntelliJ IDEA (2020.1 or later);
Go to the Project Structure and set your Project Language Level to Java 14 (remember, as well, to set Java 14 as your Project SDK, if not done yet).
See more here.

I try to make the Firebase authentication work I added the different dependencies in the gradle file but when I launch the app I get an error:http://prntscr.com/ik0xcc
http://prntscr.com/ik0y2h
Here are my dependencies: http://prntscr.com/ik0xrs
Change your build dependencies to use:
com.firebaseui:firebase-ui:3.2.1
That is the version compatible with Firebase SDK 11.8.0.

We want to update our published app in google play. But I want to confirm can we fully change android source code expect package name. We have our .jks reserved and we want to update graphics in app not App Icon. We forget our signed key details. Can we again rebuilt signed details with existing .jks file. Please suggest.
Thanks in Advance.
If you have lost your signature key, then you can't update your app. This is why Google Play introduced Google Play signing. Google signs the app for you, takes care of the keys, and if you lose your they can migrate you to a new upload key.
If you aren't using Google Play App signing there is nothing you can do - the android system requires you to sign an update with the same key.
Yes you can change the the entire source code. All you need to Update your app is :
Use the following checklist to make sure your new APK is ready to
update your existing users:
The package name of the updated APK needs to be the same as the
current version.
The version code needs to be greater than that
current version. Learn more about versioning your applications.
The updated APK needs to be signed with the same signature as the
current version.
As general practice you can install one of the old APKs generate a new signed and install it. If it installs without any issue you are good to go.
yes, you can change the source code but remember following things before update :
keystore (same that used to build app)
Check backward compatibility
Don't change package name
update version number (like previous 1.0 update to 2.0 or 1.1 something)

I'm not able to find out why does the manually importing any project even a very small app like "hello World" is not importing successfully.
I receive lots of compilation errors saying that name is not resolved.
Basically name could be anything, it could be variable, it could be package or even class name, it can't be resolved by eclipse.
But when i made explicitly that project into eclipse - it works fine? please help me out?
Try to add new system library, this is like common where we get errors.
