使用AndroidStudio时候导入开源项目ImageLoader lib包时，出现错误
Error:Execution failed for task ‘:app:dexDebug‘.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
E:\android_studio\sdk_studio\android-sdk-windows\build-tools\21.1.1\dx.bat --dex --no-optimize --output F:\github_workspace\DailyTest\app\build\intermediates\dex\debug --input-list=F:\github_workspace\DailyTest\app\build\intermediates\tmp\dex\debug\inputList.txt
Error Code:

Output:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

解决如下：在app的 build.gradle中添加所有support包
configurations {
all*.exclude group: ‘com.android.support‘, module: ‘support-v4‘
是由于并不是只有一个扩展项目 导入support-4，需要统一管理。
AndroidStudio 导入imageloader项目lib包，错误处理
