android - 谷歌地图 v1 在 Android 10 中崩溃

Question

我正在尝试在我的 Android 应用程序中使用 google map v1，但只要我在 Android 10 中打开 map Activity ，应用程序就会崩溃。

*FATAL EXCEPTION: DataRequestDispatcher

构建.gradle

android {
    compileSdkVersion 28
    buildToolsVersion "25.0.2"
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 26
        multiDexEnabled true
        useLibrary 'org.apache.http.legacy'
    } 
    dependencies {
    provided files('libs/maps.jar')
     compile files('libs/org.apache.http.legacy.jar')
    compile files('libs/httpclient-4.0.3.jar')
}

Answer 1

对 Apache HTTP 客户端的支持是 removed从 Android 9 开始。您需要做的是添加以下声明:

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

在 <application> 内你的元素AndroidManifest.xml .

请注意，如果您使用(或更新为)com.google.android.gms:play-services-maps:16.1.0或以上，那么你根本不需要添加它。有关详细信息，请查看 Google 的 documentation .

希望这对您有所帮助!
