Android7解决plus.runtime.openFile方法打开文件无响应问题（需本地打包并修改SDK）

需修改的类：pdr.jar\io\dcloud\common\adapter\util\PlatformUtil.class

具体方法请参见：解决 Android N 7.0 上 报错：android.os.FileUriExposedException

另外调试中还发现一个问题：

** PLEASE READ ****

• New versions of the Android SDK no longer support the Crypto provider.
• If your app was relying on setSeed() to derive keys from strings, you
• should switch to using SecretKeySpec to load raw key bytes directly OR
• use a real key derivation function (KDF). See advice here :

此问题的解决请参见：Android：7.0 后加密库 Crypto 被废弃后的爬坑指南
需修改的类：pdr.jar\io\dcloud\common\adapter\util\DCloudTrustManager.class

希望dcloud团队能更新此类问题
