Android Module Build Failure - KrollCallback/KrollFunction

You must Login before you can answer or comment on any questions.

New to Android Development... trying to build module that previously worked (before 1.8.0.1) and I'm trying to make it compatible by re-building...

I got a lot of deprecation errors so changed every mention of KrollCallback to KrollFunction in the java file... now I'm getting this:

I ran into the same issue just a minute ago... 

[javac] /Users/czery/Desktop/titanium-barcode/src/com/mwaysolutions/barcode/TitaniumBarcodeModule.java:26: cannot find symbol
    [javac] symbol  : class KrollFunction
    [javac] location: package org.appcelerator.titanium.kroll
    [javac] import org.appcelerator.titanium.kroll.KrollFunction;
Does anyone have an attempt how to solve this?

  • Did yours give you this error before changing KrollCallback to KrollFunction: 

    [javac] /Users/matthew/Documents/GitHubRepositories/titanium-c2dm/src/com/findlaw/titanium/c2dm/C2dmModule.java:50: cannot find symbol
    [javac] symbol  : class KrollCallback
    [javac] location: class com.findlaw.titanium.c2dm.C2dmModule
    [javac]         messageCallback = (KrollCallback)options.get("callback");
    [javac]                            ^
    [javac] Note: Some input files use or override a deprecated API.
    Looks like identical problem... I actually need to compile that barcode module next...

  • Yupp, changing KrollCallback to KrollFunction caused this error for me.

  • Change import org.appcelerator.titanium.kroll.KrollFunction; to import org.appcelerator.kroll.KrollFunction;

    then KrollFunction will be found

Has anyone had any luck here? I've tried to follow the module porting guide as close as I can and I've resolved all errors but this one: 

[javac] warning: The following options were not recognized by any processor: '[kroll.checkTiContext]'
    [javac] /Users/matthew/Desktop/titanium-barcode/src/com/mwaysolutions/barcode/TitaniumBarcodeModule.java:137: cannot find symbol
    [javac] symbol  : method callAsync(org.appcelerator.kroll.KrollObject)
    [javac] location: interface org.appcelerator.kroll.KrollFunction
    [javac]                     cancelCallback.callAsync(getKrollObject());
    [javac]                                   ^
    [javac] Note: Some input files use or override a deprecated API.
    [javac] Note: Recompile with -Xlint:deprecation for details.
    [javac] 1 error
