我想添加融合的位置服务,但它告诉我一些错误。 帮助我。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "27.0.1"
    defaultConfig {
        applicationId "com.example.adil.bloodbankapplication"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

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

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

只需要做以下几点:

build.gradle

(module:app)


android {
            ....
      defaultConfig {
              multiDexEnabled true // enable mun
      }
}

并在构建中添加以下依赖项。Gradle应用程序级别文件

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
} 

我所要做的就是在文件>项目结构>应用>口味中将最低SDK版本设置为21

添加android/app/build.gradle文件

 defaultConfig {
        applicationId "com.ubicacion"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
        multiDexEnabled true // ✔
        missingDimensionStrategy 'react-native-camera', 'general'
    }
multiDexEnabled true

请尝试将此添加到您的应用程序defaultConfig{}。这帮我解决了问题
