C:\Users\mlap\Downloads\temp>vab doctor Warning: could not locate keytool: vab.java.jdk_keytool: no keytool.exe could be located in "C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046" vab will not be able to sign any packages. It looks like you have a Java compiler (C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046\javac.exe) but no keytool you probably have Java JRE installed but no JDK. Please install Java JDK >= 8 or provide a valid path via JAVA_HOME The detected sdkmanager seems outdated or incompatible with the Java version used. For vab to control it's own dependencies, please update sdkmanager found in: "C:\Users\mlap\AppData\Local\Android\sdk\tools\bin\sdkmanager.bat" or use a Java version that is compatible with your sdkmanager. You can set the SDKMANAGER env variable or try your luck with vab install auto. Please see https://stackoverflow.com/a/61176718/1904615 for more help.

What did you do?

C:\Users\mlap\Downloads\temp>vab .

I try to make apk from .v file, but error is returned.

What did you expect to see?

Successfully generated apk.

What did you see instead?

Warning: could not locate keytool: vab.java.jdk_keytool: no keytool.exe could be located in "C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046" vab will not be able to sign any packages.

I really have Java JRE 8 in "C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046", but I have full new Java JDK in JAVA_HOME, detected from vab doctor (see above).

Strange. Does keytool or keytool.exe exist somewhere under C:\Program Files\Java\jdk-19? (Should reside in a bin directory)

Strange. Does keytool or keytool.exe exist somewhere under C:\Program Files\Java\jdk-19? (Should reside in a bin directory)

The keytool.exe indeed exists in: C:\Program Files\Java\jdk-19\bin

BUT, the vab, as see logs above, sees the: C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046 with JRE 8, and there is no keytool, and not work, despite, it discover the JDK 19 by JAVA_HOME in C:\Program Files\Java\jdk-19 The problem is, that vba did not search keytool in this JDK, in JAVA_HOME path, but in C:\Program Files\Common Files\Oracle\Java\javapath_target_1556046.

Additionaly, even the C:\Program Files\Java\jdk-19\bin is in my system PATH, so the keytool is accessible from everywhere.

[milen-prg]

I find, that if in system PATH the: C:\Program Files\Java\jdk-19\bin is over the: C:\Program Files\Common Files\Oracle\Java\javapath the vab, works.

BUT, I try one of the v ui examples - calculator.v: vab calculator.v and it successfully generates v_test_app.apk

The calculator.v works fine - small GUI calculator ("v run calculator.v" or even "v calculator.v" to make exe), but when I install v_test_app.apk on emulator and on my smartphone and start it - only black screen appears.

[milen-prg]

Please, can you show some working example of v program, successfully converted to android apk?

[larpon]

@milen-prg you've discovered a regression in V's regex library that was introduced here some days ago. We're looking into it.

[larpon]

@milen-prg try and update V with v up and then rebuild vab with the updated v compiler.

Feel free to open a new issue if the problem persist.

[larpon]

@milen-prg with latest v and vab - this works for me locally with V UI: vab --device auto -f "-d no_load_styles" run ~/.vmodules/ui/examples/calculator_resizable.v For V UI you currently have to pass -f "-d no_load_styles". Otherwise you'll get errors like: folder: /.vui/, error: Read-only file system.

For a normal V example this works: vab --device auto run ~/v/examples/2048

[milen-prg]

@Larpon , I do not know, unfortunately the successfully generated v_test_app.apk file on some devices and emulator shows black screen, on others (most) - closes with message "keep stopping". May be some problem with my android SDK/NDK etc. (I place up the vab doctor log about this), for now vab do not work for me.

[larpon]

Try running it with the --log flag to capture log output. Like this: vab --device auto -f "-d no_load_styles" --log run ~/.vmodules/ui/examples/calculator_resizable.v

[milen-prg]

@Larpon , no log file was created. May be, because, the v_test_app.apk file is successfully created. But when I install this v_test_app.apk in emulator / smartphone, it again displays message "keeps stopping". I uppload this apk in zip archive if you want to try. v_test_app.zip

[larpon]

Thanks, I'll have a look at it soon
