Monodroid GREF problem best practice?

Question

I have the following test code (based on standard monodroid HelloWorld)

namespace TestGREF
{
    [Activity (Label = \"TestGREF\", MainLauncher = true)]
    publi         


        

Answer 1

for(int i=0;i<10000;i++){
    var obj = new Java.Lang.Object(new System.IntPtr(i));

    //...some stuff here. Instead of Java.Lang.Object may be
    //something much more useful.

    obj.Dispose(); //Deletes an object and GREF too. 
    //Cannot be used if object is still used in dalvik VM
}

If you cannot use Dispose() (for example, unmanaged object is a part of layout, which will be used by android lated, but not by C# code), use GC.Collect() wisely. GC.Collect() kills all the GREFs to variables, which are out of usage by Mono Environment and out of current scope.
