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'
}
}
}

compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-auth:11.8.0'
compile 'com.google.firebase:firebase-database:11.8.0'

compile 'com.android.support:design:26.1.0'

compile 'hanks.xyz:htextview-library:0.1.5'
compile 'com.firebaseui:firebase-ui-database:1.2.0'
compile 'com.google.android.gms:play-services:11.8.0'
}
apply plugin: 'com.google.gms.google-services'
这将为Kotlin或Java项目完成工作。
步骤1 -在Gradle Scripts下找到build.gradle(Module:app)
步骤2 -添加multiDexEnabled true如下所示:
compileSdkVersion 29
defaultConfig {
applicationId "com.example.appname"
minSdkVersion 19
targetSdkVersion 29
versionCode 1
versionName "1.0"
multiDexEnabled true //addded
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
步骤3 -添加multidex依赖项
dependencies {
implementation 'com.android.support:multidex:2.0.0' //added
}
最后，同步你的项目。享受吧!
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
你可以跟着这个走。
Android 5.0 (API级别21)之前的平台版本使用Dalvik运行时执行应用程序代码。默认情况下，Dalvik限制每个APK只能使用一个classes.dex字节码文件。为了绕过这个限制，你可以在你的项目中添加multidex支持库:
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}
如果你的minSdkVersion设置为21或更高，你所需要做的就是在你的模块级构建中将multiDexEnabled设置为true。Gradle文件，如下所示:
android {
defaultConfig {
...
minSdkVersion 21
targetSdkVersion 28
multiDexEnabled true
}
...
}
