我正在尝试使用谷歌的感知 api，并将 GoogleApiClient 的实例注册到感知 api，但我收到了一个我在任何地方都找不到的错误。
我已按照手册进行操作，并在 api consule 中启用了感知服务。 https://developers.google.com/awareness/android-api/get-started
这就是我的清单的样子：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test.awarenesstests">
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<meta-data
android:name="com.google.android.awareness.API_KEY"
android:value="MY_KEY_GENERATED_IN_THE_DEVELOPER_CONSULE" />
</application>
</manifest>
非常简单的注册：
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
.addApi(Awareness.API).build();
googleApiClient.connect();
这是我收到的错误 - 包的 API 密钥无效 = com.test.awarenesstests .Status code received = 6
请注意，日志开头有一些奇怪的东西，对 google 服务进行 ping 并返回 403，它看起来与最终错误有关。
