Google Api 密钥丢失

Google Api Key Missing

我正在尝试使用模拟器启动 android 可穿戴设备,但它在启动时崩溃并出现以下错误:

java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

但奇怪的是我确实在清单中这样定义了它:

新编辑 "works"

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wearfare.wearapp.gpswear"
    android:versionCode="1"
    android:versionName="1.0" >

    <!-- Mark this app as an Android Wear app. -->
    <uses-feature android:name="android.hardware.type.watch" />

    <!-- Permission required for ambient mode to keep the application running. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <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="@android:style/Theme.DeviceDefault" >

        <!-- API key for the Android Maps API v2. The value is defined as a string resource. -->
        <meta-data android:name="com.google.android.geo.API_KEY"
            android:value="xxxxxxxxxxxxxxx"/>

        <!-- Reference the wearable shared library required to support ambient mode. -->
        <uses-library android:name="com.google.android.wearable" android:required="false" />

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

    </application>

</manifest>

我得到以下信息:

编辑 build.gradle

apply plugin: 'com.android.application'android {
        signingConfigs {
        }
        compileSdkVersion 22
        buildToolsVersion "23.0.1"
        defaultConfig {
            applicationId "com.wearfare.wearapp.gpswear"

            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.google.android.support:wearable:1.3.0'

        compile 'com.google.android.gms:play-services-maps:8.1.0'
    }

xxx 是我输入的 api 键,但是当 运行 项目时仍然得到相同的错误信息。有什么建议我在这里遗漏了什么吗?

提前致谢。

快到了

好的,伙计们,看起来它确实有效,但它没有显示我的地图,它是一个灰色区域。我发现我可以在长按时关闭该应用程序。

所以它没有显示我的地图可能是其他原因?

我检查了你的清单,发现里面有问题。

请在文件末尾添加</manifest>标签。

我认为灰屏的问题是您没有正确获取API密钥。请确保您已正确获取密钥。当我的密钥是为发布而不是调试模式生成时,我遇到了这个确切的问题。
