Android:如何使用比库中声明的更低的minSdkVersion(uiautomator-v18)

Question

我将较旧的Android应用迁移到Android-Studio/Gradle.测试需求uiautomator-v18需要minSdkVersion=18.但是,我希望将minSdkVersion设置为15或16.

SO在同一件事上有很多问题,但我无法解决这个问题.

Exerpt AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.searcher"
    android:versionCode="1"
    android:versionName="0.0.1" >

    <uses-sdk
        tools:overrideLibrary="android.support.test.uiautomator.v18"/>

    <!-- ... -->

</manifest>

build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.searcher"
        minSdkVersion 15
        targetSdkVersion 23
        testApplicationId "com.example.searcher.test"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.google.android.gms:play-services-analytics:8.4.0'
    compile files('libs/dagger-1.2.1.jar')
    compile files('libs/dagger-compiler-1.2.1.jar')
    compile files('libs/javawriter-2.1.2.jar')
    compile files('libs/javax.inject.jar')

    androidTestCompile(
        'com.android.support:support-annotations:23.2.0',
        'com.android.support.test:runner:0.4.1',
        'com.android.support.test:rules:0.4.1',
        'com.android.support.test.uiautomator:uiautomator-v18:2.1.1',
        'org.hamcrest:hamcrest-library:1.3',
        'org.mockito:mockito-core:1.10.5',
        'junit:junit:4.12',
        'com.google.dexmaker:dexmaker:1.1',
        'com.google.dexmaker:dexmaker-mockito:1.1'
    )
}

以上给出了错误:

Error:Execution failed for task ':app:processDebugAndroidTestManifest'.
> java.lang.RuntimeException: Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 18 declared in library [com.android.support.test.uiautomator:uiautomator-v18:2.1.1] /mypath/app/build/intermediates/exploded-aar/com.android.support.test.uiautomator/uiautomator-v18/2.1.1/AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="android.support.test.uiautomator.v18" to force usage

但我已经在使用了overrideLibrary.

如果这不可能,那么minSdkVersion"main"和"androidTest" 可能有不同之处吗？

编辑:添加风味后,我能够使用构建变体运行测试tstDebug.然而,构建它的prdDebug结尾是一个错误,说androidTest中有未知的东西(例如:) package org.hamcrest does not exist.修改后的摘录build.gradle:

defaultConfig {
    applicationId "com.example.searcher"
    targetSdkVersion 23
    versionCode 6
    versionName "0.5.0"
}

productFlavors {
    prd {
        minSdkVersion 15
    }
    tst {
        minSdkVersion 18
        testApplicationId "com.example.searcher.test"
        testInstrumentationRunner "android.test.InstrumentationTestRunner"
    }
}

// And instead of "androidTestCompile" use "tstCompile"

是不是可以告诉"Android Studio"它应该在没有的情况下构建应用程序androidTest？

你投入<uses-sdk tools:overrideLibrary ...>了src/main/AndroidManifest.xml吗？

如果是这样,请将其删除src/main/AndroidManifest.xml并尝试将以下xml放入src/androidTest/AndroidManifest.xml.

(别忘了android:minSdkVersion="18")

<?xml version="1.0" encoding="utf-8"?>
<manifest
    package="YOUR PACKAGE NAME"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-sdk
        android:minSdkVersion="18"
        tools:overrideLibrary="android.support.test.uiautomator.v18"
        />
</manifest>

一种选择是为您的测试提供产品风味:

android {
    productFlavors {
        production {
            minSdkVersion 15
        }
        uiTest {
            minSdkVersion 18
        }
    }
...
}

然后在uiTestflavor版本上运行测试.
