I'm trying to add Dagger2 to my project in Android Studio but I can't find proper dependency to paste in build.gradle. Could you help and send me the proper line?
问题:
回答1:
Installing Dagger 2 on Android Studio 2
// Application build.gradle
dependencies {
compile 'com.google.dagger:dagger:2.4'
annotationProcessor "com.google.dagger:dagger-compiler:2.4"
}
Maven Repositories:
Find the latest versions of the above dependencies in the Maven Repository:
- dagger
- dagger-compiler
Notes: Android Studio < 2.2
Older versions of Android Studio need android-apt
for annotation processing.
// Project build.gradle
buildscript {
dependencies {
// Assists in working with annotation processors for Android Studio.
// No longer needed with Android Studio 2.2+
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
}
}
apply plugin: 'com.neenbedankt.android-apt'
And
// Application build.gradle
dependencies {
compile 'com.google.dagger:dagger:2.4'
apt "com.google.dagger:dagger-compiler:2.4"
}
Notes: Dagger < 2.1
For Dagger < 2.1-SNAPSHOT the javax.annotation
is needed for the @Generated
annotation used in Dagger generated code (see github.com/google/dagger/issues/95). The annotation is not included in the Android API jar, so you'll need to use one of these libraries (see differences):
// Application build.gradle
dependencies {
compile 'javax.annotation:jsr250-api:1.0'
}
- javax.annotation:jsr250-api:1.0
- javax.annotation:javax.annotation-api:1.2
- org.glassfish:javax.annotation:10.0-b28
回答2:
You don't need the android-apt plugin anymore,all functionality that was previously provided by android-apt is now available in the Android Gradle plugin version 2.2
https://bitbucket.org/hvisser/android-apt/wiki/Migration
Update Gradle plugin to
classpath 'com.android.tools.build:gradle:2.2.0'
and Dagger dependencies to
compile 'com.google.dagger:dagger:2.4'
annotationProcessor 'com.google.dagger:dagger-compiler:2.4'
Cheers!
回答3:
dependencies {
compile 'com.google.dagger:dagger:2.0-SNAPSHOT'
}
in your app/build.gradle
and
allprojects {
repositories {
...
maven {
url "https://oss.sonatype.org/content/repositories/snapshots"
}
}
}
in build.gradle of your project.

I had some trouble with this earlier today. Here's what worked for me with the latest versions as of this date using Android Studio 2.0 preview 8:
buid.gradle (Module:app)
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
android {
compileSdkVersion 23
buildToolsVersion '23.0.2'
defaultConfig {
applicationId 'com.example.android.redacted.app'
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
repositories {
mavenCentral()
}
productFlavors {
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.google.dagger:dagger:2.0.2'
apt 'com.google.dagger:dagger-compiler:2.0.2'
provided 'org.glassfish:javax.annotation:10.0-b28'
}
build.gradle (Project:proj):
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha8'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
maven {
url 'https://oss.sonatype.org/content/repositories/snapshots/'
}
}
}
