我正在开发一个使用sqlite的Android应用 在某些设备上，一切运行顺畅 但是在某些设备上数据库被破坏了。
此外，看起来这个问题出现在特定设备上（数百个中的3个 - 所有相同型号）。所以也许在设备内部存储器上存在坏块 事实上，我可以在“小车”上重现这个问题。平板电脑（我可以很容易地重现数据库损坏） 为此，我只是在其中一个数据库表中循环插入数据。过了一会儿，数据库已损坏。在另一台设备（从未在损坏的数据库中运行的设备）上执行完全相同的操作时，数据库不会损坏。
我设法检索了sqlite数据库并运行了*** in database main ***

结果如下：
https://sqlite.org/howtocorrupt.html我已阅读$("form.signupform").submit(function(e) {
e.preventDefault(); // <-- add this
var data = $(this).serialize();
var url = $(this).attr("action");
以尝试了解我的数据库是如何损坏的。
pragma integrity_check的结果怎么办？我真的不知道如何处理这些信息。你是否注意到任何可以帮助我理解发生了什么的信息？ 关于如何在Android设备上检查磁盘完整性的任何想法（理想情况下在OS启动之前）？你认为我应该朝这个方向看吗？
