Question

我对谷歌地图实施一天半完全感到困惑。我遵循了链接中提到的所有必要步骤。 https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2

但是我一直得到以下提到的错误。我需要你的鹰眼经验。

Answer 1

你的logcat清楚地说了

引起：java.lang.IllegalStateException：中的元数据标记您应用的AndroidManifest.xml没有正确的值。预期4323000但找到0.您必须具备以下条件元素内的声明：

尝试使用<meta-data>文件中<application>标记下的manifest.xml标记添加Google Play服务版本，例如

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
