Android - 应用程序崩溃时，数据输入到数据库

我昨天问这个问题，但从来没有得到最终的解决方案。我有一个问题，当我输入数据插入到我的数据库，应用程序崩溃尝试添加它英寸我不确定这个问题，经过多次尝试清理我的代码，没有任何工作。这个错误是由我的中的sqLiteDatabase = myDB.getWritableDatabase();和addScoutInfo();造成的，但是即使在尝试清理之后仍然无法工作。这一次，我希望我所有的班级都能找出问题所在。Android - 应用程序崩溃时，数据输入到数据库

如果您的应用程序崩溃，然后有一个记录错误，如果我们不看到，那么所有你从我们得到的是假设.....请发布LOGCAT –

检查更新的文章 –

我发现我的问题 –

冲突的名称DatabaseContract.java是导致问题的原因。名称更改为

public class DatabaseContract { 
    public static abstract class NewDataInfo { 
     public static final String TABLE_NAME = "scout_table"; 
     public static final String COL_NUMBER = "TEAM_NUMBER"; 
     public static final String COL_POTICULLIS = "POTICULLIS"; 
     public static final String COL_CHEVAL_FRISE = "CHEVAL_DE_FRISE"; 
     public static final String COL_MOAT = "MOAT"; 
     public static final String COL_RAMPARTS = "RAMPARTS"; 
     public static final String COL_DRAWBRIDGE = "DRAWBRIDGE"; 
     public static final String COL_SALLY_PORT = "SALLY_PORT"; 
     public static final String COL_ROCK_WALL = "ROCK_WALL"; 
     public static final String COL_ROCK_TERRAIN = "ROCK_TERRAIN"; 
     public static final String COL_LOW_BAR = "LOW_BAR"; 
    } //End of NewDataInfo 
} //End of class

而且从代码中删除自动递增，并保持整数自编号不要紧

DatabaseContract.NewDataInfo.COL_NUMBER + " INTEGER,"
