Execute .bat from Android gradle after APK build

Question

I`m moving my project to Gradle build system. After APK build I need to sign it with manufacturer certificate.

How to execute .bat file by Gradle after APK was built?

task runSign(type:Exec) {
    println "Sign apk..."
    commandLine = ['cmd','/c','sign.bat']
}

I know just how to run .bat before build (but I need after):

preBuild.doLast {
    runSign.execute()
}

Is there a reason you can't use `signingConfigs`? http://stackoverflow.com/questions/18328730/how-to-create-a-release-signed-apk-file-using-gradle — Floern, Jan 30 '16 at 15:37
@Floern I use custom certificate from manufacture, that is not usual debug/release sign. — yuralife, Sep 29 '16 at 16:27

I've found the solution.

Go to Run -> Edit Configurations...

Choose module where you want to run task after APK build. Add new configuration after "Gradle-aware Make".

Click on icon at picture below to choose module where task is implemented and write name of it.

After this steps your custom Gradle task will be executed after APK build.

how to execute batch file after APK is generated at this location "\app\build\outputs\apk" ? My requirement is like once xyz.apk generated at "\app\build\outputs\apk" location I want to move this file to "D:/Xyz" location automatically. – Kush Patel Jan 25 '17 at 06:08
@KushPatel your batch file should be located in root of your module and be like: xcopy build\outputs\apk d:\Xyz (there is xcopy command on Windows platform) – yuralife Jan 25 '17 at 09:47

I needed to perform something similar, but additionally to that I needed to know with which product favour was built, and with what configuration.

I've ended up adding following line into build.gradle:

android {
    applicationVariants.all { variant -> variant.assemble.doLast { signAndInstall.execute() } }
    ...

And with following helper function:

//
//  Returns array for CommandLine, path, variant (arm7), configuration (debug / release)
//
def getCommandLine(path)
{
    String taskReqStr = getGradle().getStartParameter().getTaskRequests().toString()
    Pattern pattern = Pattern.compile("(assemble|generate)(\\w+)(Release|Debug)")
    Matcher matcher = pattern.matcher(taskReqStr)
    if (!matcher.find())
        return [ path ]

    String flavor = matcher.group(2).toLowerCase() + " " + matcher.group(3).toLowerCase()
    return [ path, matcher.group(2).toLowerCase(), matcher.group(3).toLowerCase() ]
}

task signAndInstall(type: Exec) {
    def batch = projectDir.toString() + '\\postbuild.bat'
    commandLine = getCommandLine(batch)
}

With following postbuild.bat:

@echo off
rem echo %0 %*
if %1. == . exit /b 0
if %2. == . exit /b 0
set InPath=%~dp0build\outputs\apk\%1\%2\app-%1-%2.apk
set OutPath=%~dp0build\outputs\apk\app-%1-%2.apk
copy /y %InPath% %OutPath% 1>NUL

You can of course configure this batch to perform anything what you like, %1 receives your product favour (e.g. arm7, arm8, fat...), and %2 receives 'debug' or 'release' as configuration.

I got the error `Could not find method execute() for arguments [] on task` so I changed `execute()` to `exec()` — denispyr, Jun 03 '20 at 17:11
