Question

我是Android新手，我试图在我的应用中实现谷歌地图。我按照提到的所有程序生成了API密钥，但我没有得到输出。显示灰色区域很简单，谷歌写在页面的左侧。我的代码如下。我已生成apk文件并在移动设备上进行测试。我也启用了Google Maps Android API

activity_maps.xml

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:id="@+id/map" tools:context=".MapsActivity"
class="com.google.android.gms.maps.SupportMapFragment" />

AndroidManisfest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.namrathasrinivas.maps" >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
        <!--
     The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
             Google Maps Android API v2, but are recommended.
        -->
        <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <meta-data
                android:name="com.google.android.gms.version"
                android:value="@integer/google_play_services_version" />
            <meta-data
                android:name="com.google.android.maps.v2.API_KEY"
                android:value="AIzaSyACVUB1GlGgdtbiJEK-C0P35jKTOZvJfCQ" />


            <uses-library android:name="com.google.android.maps" />
            <activity
                android:name=".MapsActivity"
                android:label="@string/title_activity_maps" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>

    </manifest>

的build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}
