Question

我想在Android项目中使用Google Maps Geocoding API。所以我按行{<3}}添加google-maps-services行：

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

并且有这样的错误：

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

我该如何解决？也许添加一些proguard规则？

谢谢你的帮助！

我试图在一个空项目上实现它，它工作正常。

我看到其他人报告他们通过删除minifyEnabled true行来解决类似问题。也许你也应该尝试一下。

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'
}

//项目：地理编码

// 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()
    }
}

还有我的onCreate功能：

    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);

Android Google地图服务导致构建错误
