Cannot send daily notfication on android with java

I'm trying 1 month now to make a feature witch sends to the user one notification daily at the time the user has selected but when the onTimeSet() called i'm getting only this error below and the Notification is not coming to the user
I try these solutions below:
removing all code from onTimeSet() & startAlarm() inside my activity
changing this to SetNotificationActivity.this
Invalidate chaches / restart
Error:
E/InputDispatcher: Window handle Window{838da5a u0 com.george.igrow/com.george.igrow.SetNotificationActivity} has no registered input channel
SetNotificationActivity.java:
public class SetNotificationActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set_notification);
final Button setAlarm = findViewById(R.id.buttonAlarm);
final Button skip_btn = findViewById(R.id.button4);
setAlarm.setOnClickListener(v -> {
DialogFragment timePicker = new TimePickerFragment();
timePicker.show(getSupportFragmentManager(), "time picker");
});
skip_btn.setOnClickListener(v -> {
finish();
startActivity(new Intent(SetNotificationActivity.this, HomeActivity.class));
});
}
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
startAlarm(c);
}
private void startAlarm(Calendar c) {
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlertReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 1, intent, 0);
if (c.before(Calendar.getInstance()))
c.add(Calendar.DATE, 1);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
startActivity(new Intent(SetNotificationActivity.this, HomeActivity.class));
}
}
AlertReceiver.java:
public class AlertReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent intent1 = new Intent(context, SplashScreenActivity.class);
intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, intent1, PendingIntent.FLAG_UPDATE_CURRENT);
// Send notification for the current Alarm
NotificationHelper notificationHelper = new NotificationHelper(context);
NotificationCompat.Builder nb = notificationHelper.getChannelNotification();
//nb.setContentIntent(pendingIntent);
notificationHelper.getManager().notify(1, nb.build());
}
}

Action button on Notification if not clicked on certain time will do something else

I have an app that if something happens it will pop up a Notification with an action button. if it pressed it will the app running but if not for a certain amount of time it will run another code.
I'm still confused about how to make that
EDIT :
Here is The code I tried
Main Activity.java :
public class MainActivity extends AppCompatActivity {
public NotificationManagerCompat notificationManager;
public TextView mViewLabel;
public ArrayList<Integer> lst = new ArrayList<Integer>();
boolean continueThread = true;
int count =0;
Thread t;
Timer j = new java.util.Timer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
notificationManager = NotificationManagerCompat.from(this);
mViewLabel = (TextView) findViewById(R.id.textChanger);
t = new Thread(){
#Override
public void run() {
if (continueThread) {
while (continueThread) {
lst.add(70);
lst.add(71);
lst.add(72);
lst.add(73);
lst.add(74);
lst.add(75);
try {
Thread.sleep(1000);
runOnUiThread(new Runnable() {
#Override
public void run() {
Collections.shuffle(lst);
mViewLabel.setText(String.valueOf(lst.get(count)));
}
});
}catch (InterruptedException e) {
e.printStackTrace();
}
count++;
}
}
}
};
}
public void BtnStart(View view){
t.start();
j.schedule(
new java.util.TimerTask() {
#Override
public void run() {
while(continueThread){
if(lst.get(count) < 80){
sendOnChannel1();
break;
}
count++;
}
}
},
5000
);
}
public void BtnStop(View view){
if(continueThread){
continueThread=false;
mViewLabel.setText("0");
}
}
public void BtnReset(View view){
if(!continueThread){
continueThread=true;
mViewLabel.setText("Click Start To Simulate Heartbeat");
}
}
public void sendOnChannel1() {
String title = "Title";
String message = "Testing";
Intent activityIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this,
0, activityIntent, 0);
Intent broadcastIntent = new Intent(this, NotificationReceiver.class);
broadcastIntent.putExtra("toastMessage", message);
PendingIntent actionIntent = PendingIntent.getBroadcast(this,
0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_one)
.setContentTitle(title)
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setColor(Color.BLUE)
.setContentIntent(contentIntent)
.addAction(R.mipmap.ic_launcher, "Toast", actionIntent)
.build();
notificationManager.notify(1, notification);
}
if something happens it will pop up a Notification with an action button
is on this code
j.schedule(
new java.util.TimerTask() {
#Override
public void run() {
while(continueThread){
if(lst.get(count) < 80){
sendOnChannel1();
break;
}
count++;
}
}
},
5000
);

From your example. You could pass the current time into the intent.
So from your MainActivity.java
public void sendOnChannel1(View v) {
String title = editTextTitle.getText().toString();
String message = editTextMessage.getText().toString();
Intent activityIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this,
0, activityIntent, 0);
Intent broadcastIntent = new Intent(this, NotificationReceiver.class);
broadcastIntent.putExtra("toastMessage", message);
broadcastIntent.putExtra("time", Calendar.getInstance().getTimeInMillis()); //**Add here
PendingIntent actionIntent = PendingIntent.getBroadcast(this,
0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
.setSmallIcon(R.drawable.ic_one)
.setContentTitle(title)
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setColor(Color.BLUE)
.setContentIntent(contentIntent)
.setAutoCancel(true)
.setOnlyAlertOnce(true)
.addAction(R.mipmap.ic_launcher, "Toast", actionIntent)
.build();
notificationManager.notify(1, notification);
}
Then when you receive it within the NotificationReceiver.java Compare the date time etc.
public class NotificationReceiver extends BroadcastReceiver {
Integer TEN_MINUETS = 1000 * 60 * 10;
#Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("toastMessage");
long time = intent.getLongExtra("time", -1);
if(time == -1){
Toast.makeText(context, "Example, no time found", Toast.LENGTH_SHORT).show();
}
if(time + TEN_MINUETS < Calendar.getInstance().getTimeInMillis()){
//10 minutes passed do something else
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
return;
}
//10 miuntes not passed do something more?
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
}
}
Just make sure to check the intent has data etc.

No message shows up - Notification

I am trying to set a Alarm. The user selects a time with the time picker and when time comes a Notification shows up. This works perfectly. But the problem is, the User Input the name of the alarm the user wrote doesn't show up. I do NOT get a error message!
https://prnt.sc/mfs5hx
https://prnt.sc/mfs5w2
NotificationHelper.java:
public NotificationCompat.Builder getChannelNotification() {
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View frAl = inflater.inflate(R.layout.fragment_alarm, null);
titelAlarm = frAl.findViewById(R.id.eingUserAlarm);
String nameAlarm = titelAlarm.getText().toString();
return new NotificationCompat.Builder(getApplicationContext(), channelID)
.setContentTitle("Erinnerung")
.setContentText(nameAlarm)
.setSmallIcon(R.drawable.ic_one);
}
The EditText where the user can name the Alarm is inside a Fragment which can be accessed by a Navigation Drawer.
<EditText
android:id="#+id/eingUserAlarm"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="180dp"
android:hint="Was wirst du machen?" />
Also the code for the Alarm is inside my Fragment.java.
Fragment.java:
Button buttonTimePicker = fraAla.findViewById(R.id.button_timepicker);
buttonTimePicker.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment timePicker = new AlarmTimePicker();
timePicker.show(getChildFragmentManager(), "time picker");
}
});
Button buttonCancelAlarm = fraAla.findViewById(R.id.button_cancel);
buttonCancelAlarm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
cancelAlarm();
}
});
return fraAla;
}
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, hourOfDay);
c.set(Calendar.MINUTE, minute);
c.set(Calendar.SECOND, 0);
updateTimeText(c);
startAlarm(c);
}
private void updateTimeText(Calendar c) {
String timeText = "Wir erinnern dich um ";
timeText += DateFormat.getTimeInstance(DateFormat.SHORT).format(c.getTime());
mTextView.setText(timeText);
}
private void startAlarm(Calendar c) {
AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getActivity(), AlertReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 1, intent, 0);
if (c.before(Calendar.getInstance())) {
c.add(Calendar.DATE, 1);
}
alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);
}
private void cancelAlarm() {
AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getActivity(), AlertReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 1, intent, 0);
alarmManager.cancel(pendingIntent);
mTextView.setText("Wir werden nicht stören!");
}

Android How to keep Running the background service when app is killed by user?

I want a background service that keeps running always in a background? It is running on some phone but not running on customised OS phones like VIVO, OPPO MIUI etc? Service is Killed on these customised OS phone.
My Code is given below --
public class MyService extends Service
{
private static final String TAG = "MyService";
#Override
public void onStart(Intent intent, int startId)
{
// TODO Auto-generated method stub
super.onStart(intent, startId);
}
#Override
public boolean onUnbind(Intent intent) {
return super.onUnbind(intent);
}
#Override
public void onCreate()
{
super.onCreate();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
//call to onTaskRemoved
onTaskRemoved(intent);
//return super.onStartCommand(intent, flags, startId);
Toast.makeText(this, "Service Started!", Toast.LENGTH_SHORT).show();
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent)
{
return null;
}
#Override
public void onDestroy()
{
super.onDestroy();
int i = 1;
Intent intent = new Intent(this, MyBroadCastReceiver.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this.getApplicationContext(), 234324243, intent, 0);
AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 5);
if (alarmManager != null)
{
alarmManager.setRepeating(
AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
60000,
pendingIntent);
}
}
#Override public void onTaskRemoved(Intent rootIntent)
{
Log.e("onTaskRemoved", "Called!");
int i = 1;
Intent intent = new Intent(this, MyBroadCastReceiver.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this.getApplicationContext(), 234324243, intent, 0);
AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 5);
if (alarmManager != null)
{
alarmManager.setRepeating(
AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(),
AlarmManager.INTERVAL_FIFTEEN_MINUTES,
pendingIntent);
}
super.onTaskRemoved(rootIntent);
}}
I have written a Broadcast Receiver that wake ups my service for every second but it is not working. My Broadcast Receiver as follows-
public class MyBroadCastReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Log.e("MyBroadCastReceiver", "onReceive");
//if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))
{
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.O)
{
FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(context));
Job myJob = dispatcher.newJobBuilder()
.setService(MyJobService.class)
.setTag("myFCMJob")
.build();
dispatcher.mustSchedule(myJob);
}
else
{
Intent service = new Intent(context, MyService.class);
context.startService(service);
}
}
}}
I have started my service using Alarm Manager and have set the Alarm for every 5 seconds, my MainActivity.java file code is as below ---
public class MainActivity extends AppCompatActivity
{
Button btnStopService;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnStopService = findViewById(R.id.btnStopService);
//get FirebaseToken
getToken();
//start Service
startService();
//setReceiver();
btnStopService.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, MyService.class);
stopService(intent);
}
});
}
private void getToken()
{
FirebaseId firebaseId=new FirebaseId();
String token_firebase=firebaseId.getFireBaseToken();
}
private void startService()
{
Intent myIntent = new Intent(this, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
Log.e("TAG", "++++++++++222222++++++++");
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
//Calendar calendar = Calendar.getInstance();
// calendar.setTimeInMillis(System.currentTimeMillis());
//calendar.add(Calendar.SECOND, 10);
Calendar alarmStartTime = Calendar.getInstance();
Calendar now = Calendar.getInstance();
alarmStartTime.set(Calendar.HOUR_OF_DAY, 0);
alarmStartTime.set(Calendar.MINUTE, 0);
alarmStartTime.set(Calendar.SECOND, 5);
if (now.after(alarmStartTime)) {
Log.d("Hey","Added a day");
//alarmStartTime.add(Calendar.DATE, 1);
}
if (alarmManager != null) {
alarmManager.set(
AlarmManager.RTC_WAKEUP,
alarmStartTime.getTimeInMillis(),
pendingIntent);
}
Toast.makeText(this, "Start Alarm", Toast.LENGTH_LONG).show();
}}
Thanks in Advance.

To keep your service and all your application running even if the phone goes into sleep mode, your service has to call startForeground() and show a non dismissable notification.
It is also convenient to acquire a partial WAKE LOCK.
on your onStartCommand()
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, Constants.CHANNEL_NOTIFY_ID)
.setContentTitle("the content title")
.setContentText("the content text")
.setSmallIcon(R.drawable.myicon)
.setOngoing(true);
// you can add other options Builder has
startForeground(1234, mBuilder.build());

Passing data from Activity to Service

I have a problem while passing String to a Service from Activity. What I am trying to do is to pass different Strings each time I call Service. I use Intent (putExtra() method each time). The problem is that each time it shows the first String that I passed. Is there a way to implement that?
Here is my Activity, Broadcast Receiver, Service
public class MainActivity extends Activity implements View.OnClickListener{
private PendingIntent pendingIntent;
private EditText event;
private Button submit, date, time;
private static final int DIALOG_DATE = 1;
private static final int DIALOG_TIME = 2;

A service can't be stopped until it's finish. You have to wait that your current service finish to send other data. You can collect all your strings and send them all together or wait until your background service finish
