前言
尽管AS已经使用了很久，但其中会遇到的问题并没有较为合理、整齐规范的整理过，今天这篇文章就用来整理这些内容，并且后面会持续更新。希望记录下问题，也能帮助小伙伴们。

Warning:Conflict with dependency ‘com.android.support:multidex’ in
project ‘:app’. Resolved versions for app (1.0.2) and test app (1.0.1)
differ. See http://g.co/androidstudio/app-test-app-conflict for
details.Error Execution failed for
taskapp:prepareDebugAndroidTestDependencies Dependency Error. See
console for details.
解决：
在里一个项目中将build.gradle文件中依赖的包，都根据AS提示将版本改成最新的之后， 没有将project的build.gradle中的gradle版本安装提示换成新的，构建是报了此错误， 将gradle版本修改后问题解决.

Error:Execution failed for task ':app:preDebugAndroidTestBuild'.
> Conflict with dependency 'com.android.support:support-annotations' in project ':app'.
Resolved versions for app (25.4.0) and test app (27.1.1) differ.
解决：
在dependencies中添加如下代码，强制去掉提示的依赖内容
dependencies{
......
androidTestCompile('com.android.support:support-annotations:25.4.0') {
force = true
}
......
}

> Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration.
- butterknife-5.1.1.jar (com.jakewharton:butterknife:5.1.1)
Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future.
See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
解决：
在android中添加如下配置
android{
defaultConfig{
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
}
}

解决办法：
将gradle.properties文件中的jvm设置设置的值小一些。如512、1024
org.gradle.jvmargs=-Xmx512m
后来有一次，设置了这些小的值都没用。然后各种Clean,Rebuild Project,Restart Android Studio都无效，可能跟电脑的配置也是有关系的，给jvm的内存太小不够用。实在没办法解决的情况下可以卸载并重装Android Studio可以解决。但这是最终没办法的办法。一般设置一下小些的值就能够解决。
