Question

我的应用程序在下一个异常时崩溃，没有任何解释：

java.lang.RuntimeException: 
  at android.os.AsyncTask$3.done(AsyncTask.java:300)
  at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:355)

Caused by: android.database.sqlite.SQLiteException:

  at android.database.sqlite.SQLiteDatabase.insertWithOnConflict(SQLiteDatabase.java:1607)
  at android.database.sqlite.SQLiteDatabase.insertOrThrow(SQLiteDatabase.java:1505)

如何解决？

我找到了理由，因为没有从SQLiteOpenHelper调用onUpgrade，我忘记在新版本中更改DATABASE_VERSION

如何理解这种类型的SQLException
