该应用程序正在我的模拟器中工作。我使用android studio.But当我导出并安装在我的手机中时，应用程序无法正常工作和关闭。我清除了我的主要活动中的代码并再次安装并打开。 当我用android studio开始模拟时，我看到logcat如下：

有人可以帮助我吗？
当我在手机上使用usb调试时，我在这里添加了logcat，它崩溃了

我必须把数据库文件放在哪里？
答案 0 :(得分：0)
这似乎是FileUtils的权限问题 - 在数据库表上 - 检查您的应用是否拥有存储文件夹的权限，或者它是否拥有所有权。根据您的logcat，请参阅以下行：07-07 18:47:18.361 1886-1886/com.example.iratus.kvexplorer W/FileUtils﹕ Failed to chmod(/data/data/com.example.iratus.kvexplorer/databases/kv_db): android.system.ErrnoException: chmod failed: EPERM (Operation not permitted)
答案 1 :(得分：0)
我按照本教程导入我的数据库。教程说要做一个＆＃34; _id＆＃34;列作为ID.I使用此，问题解决了。 http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/
