Trying to run dimple on android phone

[pramodatre]

Hi,

I'm trying to run dimple on android phone. I was able to build the android project successfully. However, when I try to run the code, here is the error message I get:

Any suggestion on getting this working will be great!

Thanks a lot in advance!

[This is issue #394 in our internal bug tracking system]

We do not officially support Android. However, I believe that one known difference between Android and the standard JRE for Java 7 is that there is no ClassValue implementation. So either you need to fork Dimple and replace ClassValue with some other lazy caching implementation or wait until a version of Android comes out that supports it. I have heard that Nougat may include ClassValue, but do not know for sure.

FYI, I don't see ClassValue in the online API ref for the java.lang package in Android API level 24 (Nougat).
