Android谷歌地图服务导致构建错误

Question

我想在我的Android项目中使用谷歌地图地理编码API。所以我按照官方文档中的描述添加了google-maps-services:

dependencies {
    compile 'com.google.maps:google-maps-services:0.1.7'
    ...
}

时出现如下错误:

Unable to compute hash of .../release/classes.jar

我该如何修复它?也许可以添加一些保护规则?

谢谢你的帮助!

我试着在一个空项目上实现这个，它工作得很好。

我看到其他人报告他们通过删除minifyEnabled true行修复了类似的问题。也许你也应该试试。

以防万一，这是我的gradle文件:

//Module:app

    apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
    defaultConfig {
        applicationId "io.github.kylelam.geocoding"
        minSdkVersion 15
        targetSdkVersion 22
        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-v7:22.2.1'
    compile 'com.google.maps:google-maps-services:0.1.7'
}

//Project: Geocoding

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

还有onCreate函数

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // Replace the API key below with a valid API key.
    GeoApiContext context = new GeoApiContext().setApiKey("AIzaSyCZ5QqX69Hbsx7UG2eX5rMzLLd4aiYNdJ8");
    GeocodingResult[] results = new GeocodingResult[0];
    try {
        results = GeocodingApi.geocode(context,
                "1600 Amphitheatre Parkway").await();
    } catch (Exception e) {
        e.printStackTrace();
    }
    System.out.println(results[0].formattedAddress);
    TextView helloworld = (TextView)findViewById(R.id.helloworld);
    helloworld.setText(results[0].formattedAddress);
