实际上，我有两个有关Android错误的相关问题。我发布了一个应用程序的更新，该应用程序以前可以正常运行，并且可以在Nexus
One，G1和模拟器上以当前版本运行。但是，自从上次更新以来，我通过Android市场控制台收到了很多错误日志，并且无法重现该错误。该应用程序非常简单，只有两个活动，因此手动测试该应用程序应该非常容易。但是，在发布之前，经常会发现一些我找不到的错误。

所以第一个问题是，有没有办法进行更深入的测试？

我的第二个问题是关于当前错误的。找不到表的SQLite数据库似乎存在问题。我猜数据库不能首先创建，因此会出错。这是堆栈跟踪：

顺便提一句。共有三名用户使用Desire HD投诉。有已知的错误吗？
