一行中两个相同的 SQLiteExceprion

问题描述 投票:0回答:1

我使用 SQLCipher 在一行中出现两个相同的错误。

我正在检查密码是否正确。如果参数输入错误,会出现两种异常。

我查看了这个页面,看看我输入的密码是否正确。当我重复代码时,我仍然在同一行代码上得到两个完全相同的异常。我可以捕获一个异常,另一个已记录。

任务打开活动:

        binding.openDatabaseFab.setOnClickListener(new View.OnClickListener() {
            @OptIn(markerClass = ExperimentalBadgeUtils.class)
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(context, MainActivity.class);
                SharedPreferences sharedPreferences = context.getSharedPreferences("TaskCalendarPreferences", Context.MODE_PRIVATE);
                sharedPreferences.edit().putString("PassphraseMD5", TaskApplication.getInstance().md5(binding.passphrase.getText().toString())).commit();

                SharedPreferences preferences = context.getApplicationContext().getSharedPreferences("TaskCalendarPreferences", MODE_PRIVATE);
                String passphrase = preferences.getString("PassphraseMD5", "");
                Log.d("TaskCalendarLog", passphrase);
                try {
                    TaskApplication.getInstance().loadAllData();
                    startActivity(intent);
                    finish();
                } catch (SQLiteException e) {
                    Log.d("TaskCalendarLog", "Incorrect password");
                }
            }
        });

            } while (cursor.moveToNext());
            taskManager.setMaxId(id);

如果删除 try-catch 块,您将得到两个完全相同的错误。
