我想添加融合的位置服务,但它告诉我一些错误。
帮助我。

使用multidex支持应该是最后的手段。默认情况下,gradle构建会为你的APK收集大量的可传递依赖项。正如谷歌开发者文档中建议的那样,首先尝试从项目中删除不必要的依赖项。
使用命令行导航到Android项目根目录。
您可以获得如下所示的编译依赖项树。
gradlew app:dependencies --configuration debugCompileClasspath
你可以得到完整的依赖树列表
gradlew app:dependencies
然后从应用build.gradle中删除不必要的或可传递的依赖项。作为一个例子,如果你的应用程序使用名为“com.google的依赖。你可以排除你不需要的库/模块。
implementation ('com.google.api-client:google-api-client-android:1.28.0'){
exclude group: 'org.apache.httpcomponents'
exclude group: 'com.google.guava'
exclude group: 'com.fasterxml.jackson.core'
}
然后在Android Studio中选择Build > Analyze APK…
选择发布/调试APK文件以查看内容。这将为您提供如下所示的方法和引用计数。
修改应用程序或模块的build.gradle
android {
defaultConfig {
...
minSdkVersion 21 <----- *here
targetSdkVersion 26
multiDexEnabled true <------ *here
}
...
}
根据官方文件
Multidex support for Android 5.0 and higher
Android 5.0 (API level 21)
and higher uses a runtime called ART which natively supports loading
multiple DEX files from APK files. ART performs pre-compilation at app
install time which scans for classesN.dex files and compiles them into
a single .oat file for execution by the Android device. Therefore, if
your minSdkVersion is 21 or higher, you do not need the multidex
support library.
For more information on the Android 5.0 runtime, read ART and Dalvik.
https://developer.android.com/studio/build/multidex
我不知道为什么,也许是因为我在Kotlin开发,但要修复这个错误
我最后必须创建一个扩展MultiDexApplication的类,就像这样:
class MyApplication : MultiDexApplication() {
}
然后在manifest。xml中进行设置
<application
...
android:name=".MyApplication">
为了不让任何人感到困惑,我也这样做:
multiDexEnabled true
implementation 'com.android.support:multidex:1.0.3'
对于androidx,这也适用于我:
implementation 'androidx.multidex:multidex:2.0.0'
...
<应用android: name = " android.support.multidex.MultiDexApplication " >
对我没用吗
