SQLiteCantOpenDatabaseException已捕获但仍显示错误日志

Question

我正在尝试打开数据库来测试数据库是否存在。我在try和catch语句中编写代码，以便在数据库不存在的情况下捕获SQLiteCantOpenDatabaseException。

但是，即使我捕获SQLiteCantOpenDatabaseException，也会在Logcat中打印错误日志。这是正常的吗？我还没有在异常上调用printStackTrace方法。有没有办法删除异常日志？

幸运的是，即使在try和catch语句之后，应用程序仍然正常运行。

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);

    myContext = this;

    try
    {
        database = SQLiteDatabase.openDatabase(DB_PATH + DB_NAME, null,
                SQLiteDatabase.OPEN_READWRITE);
        database.close();
        Log.v("Database Log", "Database exists !!");
    }
    catch(SQLiteCantOpenDatabaseException e)
    {
        // The database doesn't exist; Lets create it

        Log.v("Database Log", "Database doesn't exists !!");
    }

logcat的
