android - 运行 map Activity 时应用程序崩溃

Question

我的项目 map Activity 不起作用
我只是将 api key 粘贴到 google_maps_api.xml 并点击运行

Logcat:

Answer 1

我在以下位置找到了另一个解决方案 Android Google maps java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/ProtocolVersion

只需将其添加到您的 list 中:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

更新:

从 Google Maps SDK 版本 16.1.0 开始，您可以跳过添加上述解决方案，因为标签已添加到 map 库的 AndroidManifest 中。

https://developers.google.com/maps/documentation/android-sdk/releases#2019-02-06

Added the following declaration to the AndroidManifest.xml to support the Apache HTTP client on Android P and above. After updating to com.google.android.gms:play-services-maps:16.1.0 you can remove this line from your own AndroidManifest.xml. (Issue 117591497)

<uses-library android:name="org.apache.http.legacy" android:required="false"/>
