清单合并失败：uses-sdk：minSdkVersion 8不能小于库中声明的版本9 [复制]

这个问题在这里已有答案：

• Manifest merger failed : uses-sdk:minSdkVersion 14 25个答案

当我尝试重建它时，我的项目中出现此错误：

错误：任务'：app：processDebugManifest'的执行失败 .

清单合并失败：uses-sdk：minSdkVersion 8不能小于库中声明的版本9 [com.google.android.gms：play-services：9.4.0] C：\ Users \ Esprit \ Desktop \ ColoringBook \ app \ build \ intermediates \ explosion-aar \ com.google.android.gms \ play-services \ 9.4.0 \ AndroidManifest.xml建议：使用工具：overrideLibrary =“com.google.android.gms.play_services”强制使用

当我在build.gradle中将8更改为9时，我得到255个错误 .

这是build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 15
    buildToolsVersion "24.0.3"

    defaultConfig {
        applicationId "com.gkcrop.coloringbook"
        minSdkVersion 8
        targetSdkVersion 17
    }

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

dependencies {
    compile 'com.android.support:support-v4:20.+'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
    compile files('libs/picasso-2.4.0.jar')
}

这是Manifest.xml：
