问题描述
我向Android Studio中的现有应用程序模块添加了一个新的库模块.主要区别在于添加了RxJava 2和Retrofit 2.更新新模块的build.gradle后,我开始出现下一个错误:
I've added a new library module to existing application module in Android Studio. The main difference was adding RxJava 2 and Retrofit 2.After updating build.gradle of new module I started to get next error:
我看到RxJava存在一些问题(我想尝试RxJava 2,在这里我同时看到RxJava 1和RxJava 2).添加所有依赖项后,问题立即出现,我们在主应用程序中不使用 RxJava
.
I see that there is some problem with RxJava (I want to try RxJava 2 and here I see both RxJava 1 and RxJava 2). The problem arises right after adding all dependencies, we do not use RxJava
in our main application.
更新:正如我在下面提到的,我检查了三个主题(您可以在下面看到).此问题:可能的重复是类似于我在下面已经提到的内容:这一个.两者都具有未考虑到我在回答中强调的实际问题的变通办法.而答案是目前尚无从Retrofit 2到RxJava 2的可用于生产的适配器"(下面的答案中描述了完整的细节).
Update:As I mentioned below, I checked three topics (you can see it below). This issue: possible duplicate is similar to the one that I already mention below: this one. Both of them have workarounds that do not take into account the real problem that I underlined in my answer. And the answer is "There is no production-ready adapter from Retrofit 2 to RxJava 2 at the moment" (full details described in answer below).
我检查了几个主题:是针对具体问题的一些具体解决方案,讨论了 rxbindings
,但是我没有使用它们,其他一些也没有解决我的问题,或者总体解决方法这一个.我尝试用Google搜索"rxjava 2和翻新2",但没有找到解决方法.
I checked several topics: first is some concrete solution for a concrete problem, second talks about rxbindings
, but I don't use them, some others also have not resolved my problem or look like total workarounds this one. I tried to google "rxjava 2 and retrofit 2" but haven't found a solution.
这是库的 build.gradle
:
apply plugin: 'com.android.library'
apply plugin: 'com.jakewharton.butterknife'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
minSdkVersion 15
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile "com.android.support:appcompat-v7:$supportLibraryVersion"
compile "com.android.support:recyclerview-v7:$supportLibraryVersion"
compile 'io.reactivex.rxjava2:rxjava:2.0.2'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'com.squareup.okhttp3:okhttp:3.5.0'
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
compile "com.makeramen:roundedimageview:1.3.0"
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
provided 'javax.annotation:jsr250-api:1.0'
compile 'com.jakewharton:butterknife:8.4.0'
testCompile 'junit:junit:4.12'
}
问题是:
为什么会出现此问题,正确的解决方法是什么?
The question is:
Why does this problem happen and what is the proper way to handle it?
推荐答案
RxJava的 second 版本应使用官方适配器:
You should use the official adapter for the second version of RxJava:
compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0 // works with RxJava 2
适配器具有版本 2.*.*
的事实并不意味着它打算与RxJava 2一起使用.
The fact that adapter has version 2.*.*
does not mean that it is intended for use with RxJava 2, as I thought.
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0' // won't work with RxJava 2
以前,您应该使用一个临时版本:这是Jake Wharton的存储库,其中将Retrofit 2修改为RxJava 2适配器.
Previously, you should use a temporary version: Here is the repository of Jake Wharton with Retrofit 2 to RxJava 2 adapter.
我在Android Studio终端中使用命令 gradlew:app依赖项
发现了这个问题,其中 app
是我的库模块的名称.在那里,我寻找了"rxjava"关键字,并发现了它的不同版本.
I found this problem using command gradlew :app dependencies
in Android Studio terminal, where the app
is name of my library module. There I looked for "rxjava" keyword and found different versions of it.
更新:2月21日,正如 Darshan Mistry 在评论中指出的,21 Square发布了适配器的正式版本.答案已更新.
Update:On February, 21 Square published the official version of adapter, as Darshan Mistry pointed out in a comment. Answer updated.
