我想添加融合的位置服务,但它告诉我一些错误。
帮助我。

你的方法太多了。
Android dex文件有65536个方法的限制。
对于初学者来说,如果你不需要谷歌播放服务API,只需要位置,请替换
compile 'com.google.android.gms:play-services:11.8.0'
with
compile 'com.google.android.gms:play-services-location:11.8.0'
你可以参考本页的方法来避免它,或者如果需要允许更多:
https://developer.android.com/studio/build/multidex.html
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.

对于颤振项目,您也可以解决此问题
打开你的\android\app\build.gradle
你应该有以下内容:
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
}
}
如果你的minSdkVersion设置为21或更高,你所需要做的就是在defaultConfig中将multiDexEnabled设置为true。像这样
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true
}
}
如果你的minSdkVersion设置为20或更低,在defaultConfig中添加multiDexEnabled true
并定义实现
dependencies {
implementation 'com.android.support:multidex:1.0.3'// or 2.0.1
}
最后,你应该:
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true // added this
}
}
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}

他的问题在这里,移除它
compile 'com.google.android.gms:play-services:11.8.0'
why?
注意:不要使用组合play-services目标。它带来了几十个库,使您的应用程序变得臃肿。相反,只指定应用程序使用的特定谷歌Play服务api。
使用你所需要的https://developers.google.com/android/guides/setup
比如位置服务
com.google.android.gms:play-services-location:11.8.0
对于云消息传递
com.google.android.gms:play-services-gcm:11.8.0
