android - Invalid maximum heap size: The specified size exceeds the maximum representable size -

i error when build project in android studio preview beta 4.
error is:

error:error: not create java virtual machine. error:error: fatal exception has occurred. program exit. error:invalid maximum heap size: -xmx4g error:the specified size exceeds maximum representable size. error:execution failed task ':q-municate_app:transformclasseswithdexfordevdebug'. com.android.build.api.transform.transformexception: com.android.ide.common.process.processexception: java.util.concurrent.executionexception: java.lang.unsupportedoperationexception

i use : https://quickblox.com/developers/sample-webrtc-android#sources project build chat video app.

i use 32 bit java installation

32 bit applications can't use 4g of ram. hence size exceeds maximum representable size

you either need use smaller heap, or use 64 bit java
