When I try to compile (not execute) one of my projects, I recently get the following error:
Tool /usr/bin/java execution started with arguments: -jar /Applications/android-sdk-mac_x86/platform-tools/lib/dx.jar --no-strict --dex --output=obj/Debug/android/bin/classes.dex obj/Debug/android/bin/classes /Developer/MonoAndroid/usr/lib/mandroid/platforms/android-8/mono.android.jar FlurryAnalytics/Jars/FlurryAgent.jar Jars/android-support-v4.jar

Other projects build as expected. I think I need to increase the heap size for this java build step? But how?
OutOfMemoryError: Java heap space. 1) An easy way to solve OutOfMemoryError in java is to increase the maximum heap size by using JVM options "-Xmx512M", this will immediately solve your OutOfMemoryError.
There are several ways to eliminate a heap memory issue: Increase the maximum amount of heap available to the VM using the -Xmx VM argument. Use partitioning to distribute the data over additional machines. Overflow or expire the region data to reduce the heap memory footprint of the regions.
lang. OutOfMemoryError exception. Usually, this error is thrown when there is insufficient space to allocate an object in the Java heap. In this case, The garbage collector cannot make space available to accommodate a new object, and the heap cannot be expanded further.
There is an option in Xamarin Studio to increase the Java Heap Size.
Project Options -> Android Build -> Advanced -> Java Heap Size.
