android build error
error message: sdk/platforms/android-8/tools/aapt": java.io.IOException: error=2, No such file or directory
solve:
The problem seemed to be that the Android executables requires 32 bit libraries that are not available in Ubuntu 64 by default. To solve this I downloaded the execellent getlibs application which is a utility for automatically resolving dependencies for 32-bit programs on a 64 bit system. So I went into platforms/android-1.6/tools in the Android SDK installation folder and executed:
getlibs aapt
which installed and upgraded the following libraries:
The following NEW packages will be installed:
ia32-libs lib32asound2 lib32gcc1 lib32ncurses5 lib32stdc++6 lib32z1
libc6-i386
The following packages will be upgraded:
libc6 libc6-dev
After this was done I went back into Eclipse, did a project clean and refresh and after that I was able to start the Android emulator successfully. Hopefully this may help someone who''s in the same situation.

总结
可以看出，笔者的工作学习模式便是由以下 「六个要点」 组成：
❝ 多层次的工作/学习计划 + 番茄工作法 + 定额工作法 + 批处理 + 多任务并行 + 图层工作法❞
希望大家能将这些要点融入自己的工作学习当中，我相信一定会工作与学习地更富有成效。
下面是我学习用到的一些书籍学习导图，以及系统的学习资料。每一个知识点，都有对应的导图，学习的资料，视频，面试题目。

Android Error:Execution failed for task '':app:preDebugAndroidTestBuild''. > Conflict wi...
错误内容：
Error:Execution failed for task '':app:preDebugAndroidTestBuild''.
> Conflict with dependency ''com.android.support:support-annotations'' in project '':app''. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.
我们寻找External Libraries中的27.1.1版本，删掉就行了
最后在build.gradle中添加如下代码
androidTestCompile(''com.android.support:support-annotations:26.1.0'') {
force = true
}
Android Error:Unable to find method ''com.android.build.gradle.api.BaseVariant.getOutputs()Lja...
问题：Error:Unable to find method ''com.android.build.gradle.api.BaseVariant.getOutputs () Ljava/util/List;''.
Possible causes for this unexpected error include:<ul><li>Gradle''s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
build.gradle 如下：
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath ''com.android.tools.build:gradle:3.0.0''
classpath ''com.jakewharton:butterknife-gradle-plugin:8.4.0''
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
查阅了很久发现其实是 Android Studio3.0 与 butterknife 的冲突，github 上面已经有了这个问题 issue，JakeWharton 大神也给了相关解释，暂时的解决方法是降至 8.4 的版本。
