The issues is our method reaches 64k size.
Easy solution for this issues is we need to reduce our function or we need to remove few library which is not necessary.
Best solution is we can use  ant build to take apk. and create build.xml file to  split our library in to two files and we can inject that library in runtime.
We solved that issues buy using ant build.

One more option is available in android studio they have introduced a feature called multiple dex file so using that we can over come this issues.
