Currently I am evaluating FGX Native and I have installed Rad Studio 12.3 and the Trial version of FGX, The project compiled successfully, but when I try to run I got:

[Exec Error] FGX.Delphi.Android.Targets(118): The command "gradlew app:build" exited with code 1.

FMX project run without problems.

Any help?

sorry, probably the reason is that this link to a closed part of the forum for users with an active subscription

i try repeat that post:

The detailed reason for the crash can be found in the bottom Output tab. The error is accompanied by a detailed explanation of what to do.

In the example above, the project specifies TargetSDKVerison = 30, however, the acceptable level is not lower than 31.

please pay more attention - use the Output tab in the bottom of a page, but not the Build tab ;

We can see "Unsupported class file major version 68" error. What is meaning - i don't know. May be it's know google, but i hope that @Yaroslav Brovin is knowing better. It will need to wait his message )))

This information i found on the stackoverflow:

What version of Java is your project using? The error you received is almost certainly caused by an unsupported Java version. I would try Java 17.

Edit: Major Version 68 is Java 24, if you're working with an older project this is almost certainly not supported. Try Java 17.

So do I need to update Java? Which version do you recommend installing?

Thank you,

I reinstalled Java 21, but I’m still getting the same error when trying to deploy the project.

Should I install 32bit?

I think we need to wait @Yaroslav Brovin

Thank you, we will wait to @Yaroslav Brovin

I tried various versions of Java and uninstalled FGX and reinstalled it again. I also tried different Android SDKs (25, 29,35...), also, I did many things ending with one result: the same error when using FGX and FMX projects run without any problem.

Hello @yanchun ,

1. Did you specified correct java version in Android Profile SDK in IDE?

2. Did you JAVA_HOME enviorument variable point on Java 21?

   

Still the same error

@Yaroslav Brovin I don't think that this error is related to Java, I still got the same error when trying to deploy.

I see that it is still referring to the wrong Java path, I deleted that path, and wow it's working.

Thank you all :-)

Такая же проблема при деплое простого приложения с одной пустой формой которое было мной создано [Exec Error] FGX.Delphi.Android.Targets(120): The command "gradlew app:build" exited with code 1.

Предыдущий пользователь решил свою проблему исправлением этих путей @Yaroslav Brovin , а я что неправильно делаю?
