Android 在数据库中存储位图。怎么了？

android mysql

Android 在数据库中存储位图。怎么了？,android,mysql,bitmap,Android,Mysql,Bitmap,这是我的数据库列：您可以在最后一列中看到我放置了BLOB @Override public void onCreate(SQLiteDatabase db) { db.execSQL("create table " + TABLE_NAME + " (ID TEXT PRIMARY KEY,PASSWORD TEXT,FNAME TEXT,SNAME TEXT,BIRTHDATE TEXT,MATHGROUP TEXT,GENDER TEXT, PROFILEIMAGE BLOB)"

这是我的数据库列：您可以在最后一列中看到我放置了BLOB

  @Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table " + TABLE_NAME + " (ID TEXT PRIMARY KEY,PASSWORD TEXT,FNAME TEXT,SNAME TEXT,BIRTHDATE TEXT,MATHGROUP TEXT,GENDER TEXT, PROFILEIMAGE BLOB)");
}

我要求用户从图库中选择一幅图像。图像保存在位图中。我有位图。当我想插入数据时，我需要将位图转换为字节[]。因此：

ByteArrayOutputStream stream1 = new ByteArrayOutputStream();
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream1);
                        byte [] buffer = stream1.toByteArray();

然后我插入数据。（该方法在DatabaseHelper类中定义）

我成功地插入了这一点。所以第一个用户现在是sigen。但是我现在不能做更多了。如果用户输入ID和pass，我开始检查他的详细信息与数据详细信息的匹配，应用程序将失败（带注释退出）！我无法访问数据库信息。 BLOB列（或者我放在其中导致数据库崩溃的内容）肯定存在问题。我假设，因为当我删除该列时，登录没有问题。代码有什么问题

这里是Logcat

应用程序失败

-是否有堆栈跟踪？我对编程有点陌生，因此我不知道如何显示日志文件和堆栈跟踪。让我看看你如何使用Android studio？要进入Logcat（查看堆栈跟踪/查看出错原因），请单击Debug。这个窗口在调试器选项卡中显示线程和变量，在控制台选项卡中显示设备状态，在Logcat选项卡中显示系统日志。我不知道这是否有帮助。。。
