问题解决

后来发现时webviewGoogle 编译Android.mk的问题。

else
# if the first_api_level property is undefined, this is new launch

# preload WebView full apk by default

# SUN:jicong.wang add for remove chrome end

endif

include $(CLEAR_VARS)
LOCAL_MODULE := WebViewGoogle
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_TAGS := optional
LOCAL_BUILT_MODULE_STEM := package.apk

LOCAL_MULTILIB := both

我们添加一个

# SUN:jicong.wang add for remove chrome start
ifeq ($(strip $(SUN_REMOVE_CHROME)),true)
_gms_preload_webview_type := full
else
_gms_preload_webview_type := stub
endif
# SUN:jicong.wang add for remove chrome end

让webviewGoogle 编译时用full的apk就可以了。
