Question

我是Android的初学者我正在尝试编写使用Android Place API的应用。但当我将手机连接到互联网时，这个地方API在打开后立即关闭，当我断开互联网并打开PlacePicker时它没有关闭但是当我打开PlacePicker并重新连接到互联网并输入一些搜索时：无法加载搜索结果我看了这个： Android Place Picker closes immediately after launch 我检查了所有的建议，但一直都是一样的 Logcat没有错误我的英语不好，但我希望你能理解我： - ）

下面添加了代码体现：

    <?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>



<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/key_api">
    </meta-data>

    <activity android:name=".MainActivity">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

gradle这个

也许有些人有想法

Answer 1

您必须在Androidmanifest Application标签中添加apiKey

<meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="AIzaSyD9MY-KYYF-lSXs_mOAZHY"/>

Answer 2

确保您已启用 Places API ，不 Maps API：

这是一个常见的错误。在Google Cloud Library上找到它。然后创建API密钥并将其添加到清单中。您可以按this guide限制访问您的应用。

打开
