Android studio使用androidannotations所出现的问题

最近在使用Android studio，用到了androidannotations的库，但是有一些坑，为了记录一下，以备忘记。

annotation的配置

project的build.gradle

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

今天和大家介绍下Android的懒人框架：annotation。

注意：很多人都添加了

上面的37行到42行的apt代码，导致不能使用，出现Cannot
get property 'processResources' on null object 的错误，

其实只要把这几行代码删除就行了。但是之后还有问题，

The AndroidManifest.xml file contains the original component, and not the AndroidAnnotations generated component. Please register LoginActivity_ instead of LoginActivity

会报出这个问题，其实这个问题很蛋疼，只需要把原来的清单配置文件中的activity名字后面添加个“_”就行了。



之前名字是MainActivity，我给换成了“MainActivity_”.就好了。
