Android API 10上的Java.Lang.VerifyError

Question

在使用api 10在仿真器Nexus S Platform 2.3.3上执行android app时出现以下错误.它适用于带有api 18的Nexus 4 Android 4.3.AppDatabase扩展了SQLiteOpenHelper.

码:

 public class AppController extends Application {

     [...]

     private static AppDatabase mDbo;

     [...]
     try {
         // Here comes the crash, it crashes immediately, i cannot step into 
         mDbo = new AppDatabase( AppDatabase.NAME,null, new AppSQLiteCursor(),AppDatabase.VERSION) ;

      }
  }

Answer 1

我终于找到了VerifyError异常的罪魁祸首.这是由于SQLiteCantOpenDatabaseException,直到API 11才包含它.仅使用SQLiteException来捕获AppDatabase类中的错误.
