Android Service Compile failure

General Help

Using Delphi 11.2 to try to compile an existing Android project that has an Android service, I’m getting an error whilst linking the service. Creating a new Android Service project gives the same error:

[Exec Error] The command ""C:\Program Files\Eclipse Adoptium\jdk-11.0.15.10-hotspot\bin\javac" -g -Xlint:deprecation -source 11 -target 11 -encoding UTF-8 -d "C:\Users\Admin\Documents\RAD Studio\Projects\AndroidServiceTest3\JavaClasses\Project1" -classpath "C:\Users\Public\Documents\Embarcadero\Studio\22.0\CatalogRepository\AndroidSDK-2525-22.0.46141.0937\platforms\android-32\android.jar";"c:\program files (x86)\embarcadero\studio\22.0\lib\android\Debug\core-1.5.0-rc02.jar";"c:\program files (x86)\embarcadero\studio\22.0\lib\android\Debug\fmx.jar" --system "C:\Program Files\Eclipse Adoptium\jdk-11.0.15.10-hotspot" .\Android\Debug\Project1.java .\Android\Debug\Project1ProxyInterface.java" exited with code 1.

Since “Exit code 1” isn’t particularly useful, I ran it from the command line with the following result:

Google isn’t being very useful with providing any clues as to what’s going wrong.

Has anyone else run into this and have a solution or have any suggestions?

I’m assuming this means it was a project created in an earlier version? If so, one thing you could try is to remove the .java files in the service project folder and rebuild (Delphi recreates the .java files).

Hi David,

Thanks for the suggestion. I just tried it but no change.

You’re right that I’m trying to compile a project created in an earlier version, but since I’m getting the same error with a new project, I wasn’t too hopeful that doing this would fix it. Was certainly worth a try though.

Any other suggestions?

Can you double check your SDK settings in Delphi for Android? Make sure there’s no invalid entries

That was it - even though I had selected to install the Android SDK during the Delphi install, it wasn’t actually installed properly.

I found the following page:
https://dannywind.nl/delphi/android-sdk-for-delphi-11-2-alexandria/

The actual steps to resolve the problem were (at an elevated command prompt):

CD "C:\Users\Public\Documents\Embarcadero\Studio\22.0\CatalogRepository\AndroidSDK-2525-22.0.46141.0937\cmdline-tools\latest\bin"
sdkmanager "build-tools;32.0.0"
sdkmanager "platform-tools"
sdkmanager "platforms;android-32"

Strange that it allowed me to compile a regular Android program and only failed when it tried to link an Android service…
