android apk 升级代码

在闪屏中处理升级。

加入两项权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

style.xml中加入以下代码，去掉标题栏

<!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        <item name="android:windowNoTitle">true</item>
    </style>
