我在创建新的sqlite数据库方面遇到问题，它主要起作用，但我们的一些三星Galaxy S III客户在安装我们的应用程序后报告崩溃。我们发现问题是当sqlite调用 write（）方法时，它只在客户使用exFAT格式化外部SD卡时才会发生（三星支持他们的某些手机）。 奇怪的是，创建文件夹工作，创建空数据库文件也有效，然后崩溃。 它只发生在股票三星ROMs，在自定义rom与exfat它完美的工作。 如何解决这个问题呢？ 谢谢

我们终于在SGS III上解决了这个问题，这是一个很好的解决方法 - 我们设置临时文件默认存储在内存中而不是sd-card（SQLITE_TEMP_STORE = 2编译参数），它似乎有效。
