我在应用程序中面临与SQLiteDatabase相关的一个问题。应用程序没有崩溃。这是我在Logcat中收到的日志。

以上错误是否正常？
下面是代码。在调用close（）方法时，我遇到了错误。
public static synchronized SQLiteManager getInstance(Context context) {
if (mInstance == null) {
mInstance = new SQLiteManager(context.getApplicationContext());
}
return mInstance;
}
public SQLiteDatabase open(boolean getWritable) throws SQLException {
if (getWritable) {
database = MySQLiteHelper.getInstance(mContext).getWritableDatabase();
} else {
database = MySQLiteHelper.getInstance(mContext).getReadableDatabase();
}
return database;
}
public void close() {
database.close();
}
