Error building Player: CommandInvokationFailure: Unable to convert classes into dex format. See the Console for details. C:/Program Files/Java/jdk1.8.0_05\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir="F:\adt-bundle-windows-x86_64\sdk\tools" -Dfile.encoding=UTF8 -jar "D:\develop\Unity5.3.7\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -warning: Ignoring InnerClasses attribute for an anonymous inner class (com.tendcloud.tenddata.game.ae) that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a compiler that did not target the modern .class file format. The recommended solution is to recompile the class from source, using an up-to-date compiler and without specifying any "-target" type options. The consequence of ignoring this warning is that reflective operations on this class will incorrectly indicate that it is *not* an inner class.rouble writing output: Too many method references to fit in one dex file: 67088; max is 65536. You may try using multi-dex. If multi-dex is enabled then the list of classes for the main dex list is too large.

解決方法：

1.去掉不需要的jar包

2.導(dǎo)出android studio工程使用多個multi-dex:true 選項
