Android App+库与appcompat版本冲突

Question

我正在开发一个应用程序app和一个库（Android模块）lib。它们在不交互时没有问题：在导入库后，Android Studio搞乱了build.gradle设置，我无法恢复。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "it.mydomain.myapp"
        minSdkVersion 19
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }

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

dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile 'com.android.support:appcompat-v7:21.0.3'
     compile project(':mylib.mydomain.it')
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }

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

        debug {
            debuggable true
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.google.android.gms:play-services:6.5.87'
}

和其他98个类似的：都与主题问题有关。

还有其他消息引用值v11、v14，例如：

Answer 1

'com.android.support:appcompat-v7:21.0.3'需要API 21。

您必须用API21编译您的项目。使用：

compileSdkVersion 21
