Manifest mergeing - Android studio 0.8.1 upgrade b

I have just upgraded to Android Studio 0.8.1 and upgraded build tools ect. from Android Studio 0.6

But then I get this build error:

A problem was found with the configuration of task ':processDevelopmentDebugResources'.

File 'C:\ProjectFolder\build\manifests\DevelopmentDebug\Development\debug\AndroidManifest.xml' specified for property 'manifestFile' does not exist.

But I can't figure out what the problem is. The folder manifests under build does not exists.
I suspect it has something to do with the last part of my code that replaces values in the manifest file. There is something about "Fixes in the manifest mergers" changed in build tools changelist, but I don't know if that is related. But then again - the folder does not exists and this code should change some files in it.

Any clue?

Edit 1: I just tried to comment the "variant.processManifest.doLast" part out and it works, so the issue is with this code. (Why haven't I tried that before..)
But what has changed in the last version that make this code fail? It worked before the upgrade.

Edit 2: See comments under ianhanniballake's answer.

This is my build.gradle file:

回答1:

This is most likely due to the new manifest merging becoming the default. One benefit of the new manifest merging is that you don't have to use this approach - instead, you can define custom placeholders and have them inserted into the merging process:

android {
    defaultConfig {
        manifestPlaceholders = [ activityLabel:"defaultName"]
    }
    productFlavors {
        free {
        }
        pro {
            manifestPlaceholders = [ activityLabel:"proName" ]
        }
    }

will substitute the placeholder in the following declaration:

<activity android:name=".MainActivity" android:label="${activityLabel}" >

Note: you can also compose multiple placeholders together such as android:label="${appName}${appType}" to segment a string appropriately and reduce retyping the same information.
