Place API 打开后立即关闭

Question

我是 Android 的初学者 我正在尝试编写使用 Android Place API 的应用程序。 但是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：可以不加载搜索结果 我读到这个： 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:-)

下面添加代码 清单：

    <?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>

也许你们中的一些人有一个想法

Answer 1

确保您已启用 Places API，并且未 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。您可以关注this guide 以限制其访问您的应用。

Answer 2

您必须像在 Androidmanifest Application 标签中一样添加 apiKey

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