Android : Android Cordova java.lang.OutOfMemoryError when try to pass JSONArray to PluginResult

I have pretty simple plugin API and sometimes the Application crashes with : java.lang.OutOfMemoryError:

private boolean getPreviewGroups(final CallbackContext callbackContext) {

        this.cordova.getThreadPool().execute(new Runnable() {
            public void run() {

                try {
                    // contains JSONArray of previewGroups, and boolean isCreate
                    JSONObject previewGroupsResponse = WmGroupsMgr.getPreviewGroups();

                    callbackContext.success(previewGroupsResponse); // <- Crash from this row
                } catch (Exception e) {
                    reportPluginError(e, callbackContext);
                }
            }
        });

        return true;

    }

Is this any safety way to pass big data through PluginResult?

Thanks,
