No "unaligned" apks are generated with gradle plugin 2.2.0, breaking Spoon runner

Question

Using android gradle plugin 2.2.0:

buildscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2/" }
    }

    dependencies {
        classpath "com.android.tools.build:gradle:2.2.0"
    }
}

and running ./gradlew assembleDebug assembleDebugAndroidTest:

with 2.2.0:

app-debug.apk
app-debug-androidTest.apk

with 2.1.3:

app-debug.apk
app-debug-unaligned.apk
app-debug-androidTest.apk
app-debug-androidTest-unaligned.apk

Based on this google issue: https://code.google.com/p/android/issues/detail?id=212591 and comment here: https://code.google.com/p/android/issues/detail?id=212591#c15:

Hi, we don't generate unaligned apks any more. As part of the improvements to speed things, we generate the apk already aligned. So, instead of two, you just get the final one.

Spoon requires these "unaligned" apks to run it's test runner:

java -jar spoon-runner-1.7.0-jar-with-dependencies.jar \
    --debug --fail-on-failure --adb-timeout 90 --no-animations \
    --apk app-debug.apk \
    --test-apk app-debug-androidTest-unaligned.apk

Error:

12:06:48 I/InstrumentationResultParser: test run failed: 'Instrumentation run failed due to 'java.lang.NoClassDefFoundError''
2016-09-23 12:06:48 [STRL.testRunStarted] testCount=0 runName=<>.test

12:06:48 I/XmlResultReporter: XML test result file generated at /<>/spoon-output/junit-reports/emulator-5554.xml. Total tests 0,

It looks like Spoon only takes in the "unaligned".

Exception in thread "main" java.lang.IllegalArgumentException: Instrumentation APK path does not exist.

@antonio It looks like Square needs unaligned. See here https://github.com/square/spoon. — Jared Burrows, Sep 23 '16 at 20:13

Before 2.2, the gradle plugin would generate an unaligned apk and then run zipalign to align it. So, two apks were produced one with "-unaligned" and one, aligned without any particular markings.

With 2.2 there were many improvements in the build pipeline related to this:

APKs are now built incrementally, meaning when a single file is changed, only that file is updated in the APK.
APKs are generated aligned, no need for an extra alignment step.

The last of these two enable V2 signatures in the APK (https://source.android.com/security/apksigning/v2.html): full-APK signatures that are resistant to any changes in the APK (and faster to verify). This means zipalign can no longer run on APKs that have these signatures enabled.

So, to make the story short, starting with 2.2 packaging is faster, incremental and does not generate unnecessary unaligned APKs.

This is correct and confirmed here: https://code.google.com/p/android/issues/detail?id=223551#c4. Thanks! — Jared Burrows, Sep 24 '16 at 01:43

Have you tried setting up zipalign to false inside gradle file?

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        zipAlignEnabled false 
    }
}

You can also specify multiple buildTypes if you want

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        zipAlignEnabled false 
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

I did but it did not generate the APKs. – Jared Burrows Sep 23 '16 at 20:13
How did you build your apk? Using this path : Build/Build Apk ? – Jaythaking Sep 23 '16 at 20:15
I posted in my question: `./gradlew assembleDebug assembleDebugAndroidTest`. Did you test this locally? – Jared Burrows Sep 23 '16 at 20:27
Yes, but I used Build/Generate Signed APK which let me decide which build type I want... Then I choose debug as type and I choose debug in the list of build type – Jaythaking Sep 23 '16 at 20:37
I was asking if you tested the gradle code you posted. It does not generated "unaligned" apk files. – Jared Burrows Sep 23 '16 at 20:39

No "unaligned" apks are generated with gradle plugin 2.2.0, breaking Spoon runner
