Xamarin Android 编译报错：

COMPILETODALVIK : UNEXPECTED TOP-LEVEL error

java.lang.OutOfMemoryError: Java heap space

解决：

用记事本打开 xamarin android的项目文件 *.csproj

找到<JavaMaximumHeapSize>节点，我的配置是空的，加上1G后，编译通过。

参考：

The fix was to add this section in your .csproj file:

<PropertyGroup> 
    <JavaMaximumHeapSize>1G</JavaMaximumHeapSize> 
</PropertyGroup>

That will let Java allocate enough memory to complete your build.

That’s it! I hope someone find this post useful!
