Question

我正在尝试在我使用gradle的项目中使用Rxjava。我没有任何编译错误，但当我运行项目我的应用程序崩溃。

我认为问题来自gradle。这是我的gradle build.xml。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    flatDir {
        dirs 'lib'
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
    }

    sourceSets {
        main {
            assets.srcDirs = ['assets']
        }
    }

}

dependencies {
    compile 'com.squareup.picasso:picasso:2+'
    compile 'com.squareup.dagger:dagger-compiler:1.1.0'
    compile 'com.squareup.dagger:dagger:1.1.0'
    compile 'com.android.support:support-v4:18.0.+'
    compile 'com.squareup.retrofit:retrofit:1.2.+'
    compile 'com.netflix.rxjava:rxjava-android:0.14.+'
    compile files('lib/Parse-1.3.8.jar')
}

任何想法？

Answer 1

是的，我修好了：

compile 'com.netflix.rxjava:rxjava-core:0.+'
compile 'com.netflix.rxjava:rxjava-android:0.+'
compile 'com.squareup.retrofit:retrofit:1.5.0'

在我的 build.gradle 。

中

谢谢

Answer 2

compile 'com.netflix.rxjava:rxjava-core:0.+'是暂时的依赖 compile 'com.netflix.rxjava:rxjava-android:0.+'和Gradle automatics已解决此依赖关系并下载

Answer 3

基于 ReactiveX / RxAndroid ：https://github.com/ReactiveX/RxAndroid

最好同时使用android和java依赖项：

compile 'io.reactivex:rxandroid:1.0.1'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
compile 'io.reactivex:rxjava:1.0.14'

使用rxjava-android的问题
