Two identical SQLiteExceprion in one line
I have two identical errors in one line using SQLCipher.
I am checking the password for correctness. If the parameter is entered incorrectly, two exceptions occur.
I looked at this page to see if the password I entered was correct. When I repeated the code, I still got two exactly the same exceptions on the same line of code. One exception I can catch, the other is logged.
TaskOpenActivity:
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");
}
}
});
TaskApplication:
public void loadAllData() {
taskCalendarDBHelper = new TaskCalendarDBHelper(this);
try {
taskCalendarDBHelper.loadAllTasks();
taskCalendarDBHelper.loadAllNotes();
taskCalendarDBHelper.loadAllDayAlarms();
} catch (SQLiteException e) {
throw e;
}
}
TaskBDOpenHelper:
public void loadAllTasks() {
SharedPreferences preferences = context.getApplicationContext().getSharedPreferences("TaskCalendarPreferences", MODE_PRIVATE);
passphrase = preferences.getString("PassphraseMD5", "");
Log.d("TaskCalendarLog", passphrase);
TaskManager taskManager = TaskManager.getInstance();
//SQLiteDatabase actionsDatabase;
//actionsDatabase = SQLiteDatabase.openDatabase(DATABASE_PATH + DATABASE_NAME, passphrase, null, SQLiteDatabase.OPEN_READONLY, hook);
try {
taskCalendarDatabase = SQLiteDatabase.openOrCreateDatabase(DATABASE_PATH + DATABASE_NAME, passphrase, null, null, hook); // <--- Exception here
} catch (SQLiteException e) {
throw e;
}
//actionsDatabase = this.getReadableDatabase();
Cursor cursor = taskCalendarDatabase.query(TaskCalendarDBHelper.TASK_TABLE, null, null, null, null, null, null);
if (cursor.moveToFirst()) {
int taskInt = cursor.getColumnIndex(TASK);
int date = cursor.getColumnIndex(DATE);
int time = cursor.getColumnIndex(TIME);
int hasAlarm = cursor.getColumnIndex(HAS_ALARM);
int hasNotification = cursor.getColumnIndex(HAS_NOTIFICATION);
int isDone = cursor.getColumnIndex(IS_DONE);
int wasNotifiedIndex = cursor.getColumnIndex(WAS_NOTIFIED);
int wasAlarmedIndex = cursor.getColumnIndex(WAS_ALARMED);
boolean wasNotified;
boolean wasAlarmed;
int id = taskManager.getMaxId();
do {
if (cursor.getInt(wasNotifiedIndex) == 1) {
wasNotified = true;
} else {
wasNotified = false;
}
if (cursor.getInt(wasAlarmedIndex) == 1) {
wasAlarmed = true;
} else {
wasAlarmed = false;
}
Task task = new Task(cursor.getString(taskInt), cursor.getString(date), cursor.getString(time), cursor.getString(hasAlarm), cursor.getString(hasNotification), cursor.getString(isDone));
task.setId(id);
task.setWasNotified(wasNotified);
task.setWasAlarmed(wasAlarmed);
taskManager.getTaskList().add(task);
//Log.d("TaskCalendarLog", taskManager.getTaskList() + "");
id++;
} while (cursor.moveToNext());
taskManager.setMaxId(id);
}
cursor.close();
taskCalendarDatabase.close();
}
If you remove the try-catch block, you will get two absolutely identical errors.

Sorry for my bad English. It's Google Translate.
