java.io.NotSerializableException: android.app.PendingIntent

I am trying to create an instance of AlarmManager with pendingIntent, but I cannot understand where I am going wrong.
My android app implements a customer class (eventHandler) which is Serializable. I have converted the object of my class to a byte array in order to pass it as an extra into my alarm intent. The app starts and works fine, reading the byte array and creating the alarm intent in my object with pendingintent. The problem occurs when I try to start a second activity, get the object of my class (which is serializable) and then convert it to a byte array to be passed as an extra.
The code that is a problem is:
Intent intent = new Intent(getActivity(), EventWeatherActivity.class);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = null;
try {
out = new ObjectOutputStream(bos);
**out.writeObject(event);**
out.flush();
byte[] data = bos.toByteArray();
intent.putExtra(EXTRA_MESSAGE, data);
out.writeObject(event); - is the line causing the error. But event which belongs to eventHandler (Serializable) did run when the app began, so why is it an issue when I am starting another activity?
The error that I am getting is:

In my customer class (eventHandler event):
Intent alarmIntent = new Intent(context, NotificationReceiver.class);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = null;
try {
out = new ObjectOutputStream(bos);
out.writeObject(this);
out.flush();
byte[] data = bos.toByteArray();
alarmIntent.putExtra("imw.notification", data);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
bos.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
final int id = (int) System.currentTimeMillis();
pendingIntent = PendingIntent.getBroadcast(context, id, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);

I think the problem is that your EventHandler class contains pendingIntent field, which cannot be serialized. You should separate your EventHandler class and describe there only fields you want to serialize. Also please provide the whole listing of your EventHandler class to see what else can cause the problem. Your current listing is not full.

Yes, pendingIntent cannot be serialized, but weirdly when the app initially runs, pendingIntent runs fine within eventHandler and an alarm IS created successfully. The problem comes about when I try to then get a copy of that eventHandler object and convert it into a byte array as above so that I can pass the eventHandler object to my second activity. If I comment out the creation of a pendingIntent and alarm, the app runs fine passing the eventHandler object between activities.
So, as mentioned above I seperated the Alarm creation into a "Notification" class:
public class Notifications implements Serializable {
private PendingIntent pendingIntent;
private int notification_period;
private String notification_interval;
private Activity activity;
private Context context;
private AlarmManager manager;
private eventHandler event;
public Notifications(eventHandler event, int notification_period, String notification_interval, Activity activity, Context context)
{
this.notification_interval = notification_interval;
this.notification_period = notification_period;
this.activity = activity;
this.context = context;
this.event = event;
}
public void setAlarm()
{
manager = (android.app.AlarmManager) activity.getSystemService(Context.ALARM_SERVICE);
if(notification_period != -1 && !notification_interval.equals("-1")) {
Intent alarmIntent = new Intent(context, NotificationReceiver.class);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = null;
try {
out = new ObjectOutputStream(bos);
out.writeObject(event);
out.flush();
byte[] data = bos.toByteArray();
alarmIntent.putExtra("imw.notification", data);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
bos.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
final int id = (int) System.currentTimeMillis();
pendingIntent = PendingIntent.getBroadcast(context, id, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
if(notification_interval.equals("minute")) {
manager.setRepeating(android.app.AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), notification_period*60*1000, pendingIntent);
}
else if(notification_interval.equals("hour")) {
manager.setRepeating(android.app.AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() * android.app.AlarmManager.INTERVAL_HOUR * notification_period, android.app.AlarmManager.INTERVAL_HOUR, pendingIntent);
}
else if(notification_interval.equals("day")) {
manager.setRepeating(android.app.AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() * android.app.AlarmManager.INTERVAL_DAY * notification_period, android.app.AlarmManager.INTERVAL_DAY, pendingIntent);
}
Log.d("alarm_set", notification_period + " " + notification_interval);
}
else {
if(pendingIntent != null)
{
manager.cancel(pendingIntent);
Log.d("alarm_cancelled", pendingIntent.toString());
}
}
}
}
..and now with the above, in my eventHandler class:
public void processEvent() {
try {
dailyWeather dWeather = new dailyWeather(raw_weather);
hWeather = new hourlyWeather(raw_weather);
tag = event.get("Tag");
start_date = event.get("Start Date");
start_time = event.get("Start Time");
end_time = event.get("End Time");
location = event.get("Location");
lat = event.get("Lat");
lng = event.get("Lng");
notification_period = Integer.parseInt(event.get("Notification Period"));
notification_interval = event.get("Notification Interval");
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
LocalDate fromDate = LocalDate.parse(start_date, formatter);
LocalDateTime localTime_fromTime = LocalDateTime.parse(start_date + " " + start_time, DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm"));
LocalDateTime localTime_toTime = LocalDateTime.parse(start_date + " " + end_time, DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm"));
if (DAYS.between(LocalDate.now(), fromDate) > 7) {
bActive = false;
}
else if(LocalDateTime.now().isAfter(localTime_toTime)) {
Log.d("Expired", "End time");
bActive = false;
bExpired = true;
bContainsHours = true;
}
else {
bActive = true;
weather = dWeather.getWeather(start_date);
if (!start_time.equals("0")) {
bContainsHours = true;
}
if(notification_period != -1 && !notification_interval.equals("")) {
notificationManager = new Notifications(this, notification_period, notification_interval, activity, context);
notificationManager.setAlarm();
}
}
}catch(Exception e)
{
Log.d("Err", "Error appearing here");
e.printStackTrace();
}
}
now the app crashed when I run it from the beginning, complaining that AlarmManager is not serialized.

Out of bounds exception when confirming a user

I am trying to set up AWS Cognito email verification for my app. However, when the email verification number is typed in and the user clicks the verify button, I keep getting a
java.lang.ArrayIndexOutOfBoundsException: length=1; index=1
I understand what this means however I am learning as I go, so I am struggling to find exactly where the issue is made.
I have already researched the issues over Stack Overflow and have not found any help directly relating to this issue and amazon cognito. I have tried adjusting the array size and tried to make different catch senerios to see where the code goes wrong.
Here is the Java file that the error comes from
public class verify extends AppCompatActivity {
private static final String TAG = "Cognito";
private CognitoUserPool userPool;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_verify);
final EditText verifyCode = findViewById(R.id.verifyCode);
Button verifyButton = findViewById(R.id.verifyButton);
verifyButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new ConfirmTask().execute(String.valueOf(verifyCode.getText()));
Intent intent = new Intent(verify.this, stepTwo.class);
startActivity(intent);
}
});
}
protected class ConfirmTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... strings) {
final String[] result = new String[1];
final GenericHandler confirmationCallback = new GenericHandler() {
#Override
public void onSuccess() {
result[0] = "Successful!";
}
#Override
public void onFailure(Exception exception) {
result[0] = "Failed " + exception.getMessage();
}
};
CognitoSettings cognitoSettings = new CognitoSettings(verify.this);
CognitoUser thisUser = cognitoSettings.getUserPool().getUser(strings[1]);
thisUser.confirmSignUp(strings[0], false, confirmationCallback);
return result[0];
}
#Override
protected void onPostExecute(String result){
super.onPostExecute(result);
Log.i(TAG, "Confirmation result: " + result);
}
}
}
I expect the app to not crash and for the Amazon Cognito User Pool to show that I have verified the email.
Here is my logcat

Adding OnClickListener makes app crash

I'm working on a term project and I'm new to java and android app development. I have experience in other programming languages, though. I'm trying to reverse engineer an app to make it able to connect and send data via bluetooth. I want to make a list with all the available bluetooth devices, a button to turn on/off bluetooth, one for making the phone discoverable for other devices and another to search for unpaired devices. But every time I add an OnClickListener to the onCreate method, the app crashes before it opens. Could anyone help me out?
The source code for the app I am trying to modify can be found here:
https://github.com/pazaan/600SeriesAndroidUploader
Here is the part that seems to makes it crash:
lvNewDevices.setOnItemClickListener(MainActivity.this);
btnONOFF.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d(TAG, "onClick: enabling/disabling bluetooth.");
enableDisableBT();
}
});
btnStartConnection.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startConnection();
}
});
btnSend.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
byte[] bytes = etSend.getText().toString().getBytes(Charset.defaultCharset());
mBluetoothConnection.write(bytes);
}
});
And here is all of OnCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "onCreate called");
super.onCreate(savedInstanceState);
Button btnONOFF = (Button) findViewById(R.id.btnONOFF);

Move the code setContentView(R.layout.activity_main);
under the super.onCreate(savedInstanceState);

you are mapping the views before adding layout in your code.
your onCreate() should be
#Override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "onCreate called");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Do mapping all views

Your Error log is showing you your solution. The project is using Fabric API. So naturally you need to add Fabric API key to your project.
Do as suggested in Error log. Add following line in Android Manifest.
<meta-data android:name="io.fabric.ApiKey" android:value="YOUR_API_KEY"/>
For your API key, make a project using Fabric account and get your API key.

Android JSON Parsing Crashing Application AsyncTask

I am using a JSON parser to read the data from my JSON file and display it within my app, I was originally using this code to create arrays which works fine but now I have pasted it into a new application to make it get data from the JSON and put it onto a text field which isn't working.

You can not do any UI operation in doInBackground.
Put set text related stuff in onPostExecutemethod of AsyncTask
#Override
protected void onPostExecute(Void aVoid) {
}

remove UI component from doInBackground and update UI in postExecute method of Asynctask

You are trying to modify a View from a background thread.
View Android UI in not thread safe, and so can only be modified from the main thread.
The offence is this line in your doInBackground()
usernametext.setText(c.getString("name"));
Instead, you should return the found String from the doInBackground, override onPostExecute and set it there.
An other option is wrap is in a runOnUiThread() but honestly that's more complicated and unnecessary in this case.

You cannot use
usernametext = (TextView) TechnicianProfile.this.findViewById(R.id.abouttext);
usernametext.setText(c.getString("name"));
from .doInbackground() method, because this method is executed on background thread, but UI elements can only be changed from a main thread.
Move UI update to .onPostExecute() method.

As the error suggest "Caused by: android.view.ViewRootImpl$CalledFromWrongThreadException" you are doing wrong thing in wrong thread. Please move your setText code to onPostExecute.

You have to use publishProgress and onProgressUpdate.
