解決方案：

you have use yipianfengye/android-zxingLibrary
there is a method "initDisplayOpinion()" in his ZApplication
what you need to do is adding "extends ZApplication" in your own Application

即在manifest清單檔案中修改：

<application
        android:name="com.uuzuche.lib_zxing.MyApplication"

        ……
       >

</application>
