Hi, I use the latest version of ant, proton, sdk and ndk.
After build.bat, I get this at the end :

Code:
-compile:
    [javac] C:\protonsdk\RTBareBones\android\build.xml:149: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
    [javac] Compiling 13 source files to C:\protonsdk\RTBareBones\android\bin\classes

BUILD FAILED
C:\protonsdk\RTBareBones\android\build.xml:129: The following error occurred while executing this line:
C:\protonsdk\RTBareBones\android\build.xml:149: Reference project.libraries.jars not found.
Then I tried to replace the "<target name="-compile" ..." part inside C:\protonsdk\RTBareBones\android\build.xml from sdk-dir\tools\ant\build.xml. Then I get this output :

Code:
-compile:
    [javac] Compiling 13 source files to C:\protonsdk\RTBareBones\android\bin\classes
    [javac] C:\protonsdk\RTBareBones\android\temp_final_src\com\rtsoft\rtbarebones\BillingService.java:21: error: package com.android.vending.billing does not exist
    [javac] import com.android.vending.billing.IMarketBillingService;
    [javac]                                   ^
Any help or idea ?

Thanks
