Task

com.alipay.android.tasks.ProcessAndroidResourcesExt
从上面可以看出，mpaas项目的processDebugResources任务实现被重写了，但是inputs和outputs貌似没有变化，不排除没有指定inputs和outputs的情况，有很大的可能进行了也生成了新的文件，但是没有指定为outputs。

分析

1.ProcessAndroidResourcesExt如何被替换？
在配置阶段执行完成之后（afterEvaluate），ReplaceProcessResourceTask 将ProcessAndroidResources替换为ProcessAndroidResourcesExt

2.ProcessAndroidResourcesExt做了什么？

public void newDoFullTaskAction() throws IOException, ExecutionException {
        AaptInvoker aaptInvoker = aaptParam -> {
            List<String> params = aaptParam.getAdditionalParameters();
            List<String> origin = getAaptOptions().getAdditionalParameters();
            if (origin == null) {
                origin = new ArrayList<>();
            }
            addMoreArgs(origin); //未看出做了什么
            addIgnoreAssets(origin);
            for (String p : params) {
                origin.add(p);
            }
            getAaptOptions().setAdditionalParameters(origin);
            File inputResDir = aaptParam.getInputResDir();
            if (inputResDir != null) {
                this.inputResourcesDir = new SimpleFileCollection(new File[]{inputResDir});
            }
            superNewDoFullTaskAction();
            AaptResult aaptResult = new AaptResult();
            aaptResult.setSrcOutputDir(getSourceOutputDir());
            aaptResult.setSymbolsWithPackageNameOutputFile(getSymbolslWithPackageNameOutputFile());
            aaptResult.setTextSymbolOutputFile(getTextSymbolOutputFile());
            aaptResult.setPackageOutput(findApkOutputs().get(0));
            return aaptResult;
        };
        if (getProject().getPlugins().hasPlugin(PortalPlugin.class)) {
            AlipayResGod.doPortalAapt(getProject(), aaptInvoker, getManifestFile(), getPackageForR(), getSourceOutputDir(), PortalHelpGroovyUtils.portalData((Task) this).getBaseResJar());
        } else if (getProject().getPlugins().hasPlugin(BundlePlugin.class)) {
            AlipayResGod.doBundleAapt(getProject(), aaptInvoker, BundleProperty.getInstance().packageId);
        } else {
            superNewDoFullTaskAction();
        }
    }
  • addMoreArgs 未看出做了什么，可能反编译后代码不全，大概在Plugin为BundlePlugin时给aapt命令指定一些args
  • addIgnoreAssets 指定了默认的ignoreAssets，如果外部通过aaptOption设置则覆盖默认
  • 指定aapt的输入输出目录等
  • 判定Plugin是否使用自定义的Task
    • PortalPlugin 使用
    • BundlePlugin 使用
    • 其他Plugin不使用
  • AlipayResGod 修改资源

结论

ProcessAndroidResourcesExt 会修改资源id ，将正常的0x7f 修改 为0x02-0x7f，前提是application项目
原理可以看https://github.com/seiginonakama/ResPkgRemaker
主要修改了R.java和ap_文件

        public static final int tiny_menu_out_landscape=0x4c440007;
    }
    ...
}

_ap文件
1.resources.arsc
修改资源id
2.xml文件中的资源id
eg：layout中的string引用等

build.gradle 配置

bundle {

    packageName 'com.alipay.mobile.nebulaintegration'

}

nebulaintegration-build 中直接运行assembleDebug ，资源id会被替换为0x4f
