SPI(Service Provider Interface),是JDK内置的一种服务提供发现机制,可以用来启用框架扩展和替换组件,主要是被框架的开发人员使用,比如java.sql.Driver接口,其他不同厂商可以针对同一接口做出不同的实现,MySQL和PostgreSQL都有不同的实现提供给用户,而Java的SPI机制可以为某个接口寻找服务实现。Java中SPI机制主要思想是将...

应用经常往外部存储上写数据(可能是SD卡),这个操作可能会有多个安全问题。首先应用可以可以通过READ_EXTERNAL_STORAGE获取SD卡上存储的文件。而且如果数据中包含用户的敏感信息的话,那么需要把这些数据加密。 有漏洞的代码: file file = new File(getExternalFilesDir(TARGET_TYPE), filename); ...
