  2. 出现问题如下:
  Exception in thread "main"  java .lang.NoClassDefFoundError: junit/textui/ResultPrinter
  at java.lang.Class.forName0(Native Method)
  at java.lang.Class.forName(Class.java:169)
  at com.intellij.rt.execution.application.AppMain.main(AppMain.java:113)
  Caused by: java.lang.ClassNotFoundException: junit.textui.ResultPrinter

  原因为调用的junit  android-studiopluginsjunitlibjunit-rt.jar 下没有junit/textui/ResultPrinter 这个class文件,怎么解决呢????
  3. com.google.inject的maven配置
  <dependency>
  <groupId>com.google.inject</groupId>
  <artifactId>guice</artifactId>
  <version>1.0</version>
  </dependency>
  4. android-4.0.1.2.jar Maven配置
  <dependency>
  <groupId>com.google.android</groupId>
  <artifactId>android</artifactId>
  <version>4.0.1.2</version>
  </dependency>
  5. 用gradle编译项目时出错:
  Could not create plugin of type 'AppPlugin'
  解决方法:
  classpath 'com.android.tools.build:gradle:0.7.0' 改为 classpath 'com.android.tools.build:gradle:0.7.3'
  6. 用gradle 同步工程出现错误如下:
  Unable to load class 'org.gradle.api.artifacts.result.ResolvedComponentResult'
  解决方法:
  classpath 'com.android.tools.build:gradle:0.7.3'
  7. gradle-plugin and the gradle version说明:
  There is a relation between gradle-plugin and the gradle version. For example
  com.android.tools.build:gradle:0.6.+  -> gradle 1.8
  com.android.tools.build:gradle:0.7.+  -> gradle 1.9
  com.android.tools.build:gradle:0.8.+  -> gradle 1.9/1.10
  com.android.tools.build:gradle:0.9.+  -> gradle 1.10/1.11
  You can find gradle version used in your project in the file gradle/wrapper/gradle-wrapper.properties
  Also there is a relation between gradle-plugin and the IDE version. For example:
  Android Studio 0.3.x -> gradle-plugin 0.6
  Android Studio 0.4.x -> gradle-plugin 0.7
  Android Studio 0.4.3+ -> gradle-plugin 0.8
  Android Studio 0.5.x  -> gradle-plugin 0.9

  8. 错误问题如下:
  !!! JUnit version 3.8 or later expected:
  java.lang.RuntimeException: Stub!
  at junit.runner.BaseTestRunner.<init>(BaseTestRunner.java:5)
  at junit.textui.TestRunner.<init>(TestRunner.java:54)
  at junit.textui.TestRunner.<init>(TestRunner.java:48)
  at junit.textui.TestRunner.<init>(TestRunner.java:41)
  解决方法:(https://github.com/robolectric/deckard-gradle)
  For Intellij, go to Project Structure -> Modules -> deckard-gradle pane. In the Dependencies tab, move the Module SDK dependency (i.e. Android API 19 Platform) to be the last item in the list.
  For Android Studio, dependency ordering is currently not modifiable via any GUI. Therefore, you must modify the project iml file directly as such and reload the project:
  <orderEntry type="library" exported="" scope="TEST" name="wagon-provider-api-1.0-beta-6" level="project" />
  <orderEntry type="library" exported="" scope="TEST" name="xercesMinimal-1.9.6.2" level="project" />
  <orderEntry type="jdk" jdkName="Android API 19 Platform" jdkType="Android SDK" />
  <---make sure this is the last orderEntry
  </component>
  </module>
  9.下载android sdk和platform API参考地址:

  解决方法:???
  11. No resource found that matches the given name 'Theme.AppCompat.Light.DarkActionBar'.
