Range seekbar to trim audio

I'm trying to incorporate somehow into Android audio player, functionality of marking of the fragment of the song in the player that it is supposed to play. I see this like clipping of the fragment as in Audacity. I'm trying to get it with a range seekbar (two blue dots on a line that can be adjust) on which user mark the beginning and the end to play and when replay mode is enabled the player will play that marked section over and over again.
This player looks like this
The application is written in the Java language.

Countdown timer which runs in the background in android

Here is my fully functional code in which when I press the button, the button gets disabled and the countdown timer gets started and whenever it gets over button gets enabled. My problem is that if I leave that activity the process resets.
My question is how that can be done in the background so even if I close the application the timer runs in the background?
package com.mycompany.myapp;

public class MainActivity extends Activity {
Button btnCountdown;
TextView tvCountdown;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnCountdown = findViewById(R.id.btnCountdown);
tvCountdown = findViewById(R.id.tvCountdown);
btnCountdown.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Timer();
btnCountdown.setEnabled(false);
}
});
}
private void Timer() {
new CountDownTimer(30*1000,1000) {
#Override
public void onTick(long millisUntilFinished) {
long second = (millisUntilFinished / 1000) % 60;
long minutes = (millisUntilFinished / (1000*60)) % 60;
tvCountdown.setText(minutes + ":" + second);
}
#Override
public void onFinish() {
tvCountdown.setText("Fin");
btnCountdown.setEnabled(true);
}
}.start();
}
}

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.

Also the code for the Alarm is inside my Fragment.java.

CountdownTimer Service restarting when activity screen is re-opened

I'm trying to make a countdown timer screen on Android that will continue to count down if you back out of the app or go to different screens in the app or whatever.

int timeLeftInt = (int) Math.ceil((double) millisUntilFinished / 60000); //Whole number of minutes left, ceiling
sendBroadcastMessage(timeLeftInt);
if(timeLeftInt == 5){

}
}

Probably this happens because you're starting countdown service in onResume() and you're stopping the service in onPause()
And also in the onCreate() method of your service you're creating new instance from countdown timer.

it is showing the toast that your msg will be send after xxxx seconds but not sending msg at scheduled time.
can anybody help me plzzz

Try to use Broadcast Receive first and then start a service.
Something like that:
create a function:
public static void setRecurringAlarm(Context context, Class<?> cls, int time, int minute) {
Calendar updateTime = Calendar.getInstance();
updateTime.setTimeZone(TimeZone.getDefault());
updateTime.set(Calendar.HOUR_OF_DAY, time);
updateTime.set(Calendar.MINUTE, minute);
Intent alarm = new Intent(context, cls);
PendingIntent recurringAlarm = PendingIntent.getBroadcast(context, 654789, alarm, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarms = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, updateTime.getTimeInMillis(), AlarmManager.INTERVAL_DAY, recurringAlarm);
}
If you don't want to set a recurring alarm, just change setRepeating to set.
In your code, you need to call:
// to start the receiver at 9:00am
setRecurringAlarm(this, AlarmManagerReceiver.class, 9, 0);
So, you need to create the AlarmManagerReceiver.java:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class AlarmManagerReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent alarmService = new Intent(context, AlarmManagerService.class);
context.startService(alarmService);
}
}
And now, you need the service:
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.IBinder;
import android.preference.PreferenceManager;
public class AlarmManagerService extends Service {
private Context context;
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
context = this.getApplicationContext();
}
#Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
// Do what you need to do.
stopSelf();
}
}
In manifest:
<receiver android:name=".AlarmManagerReceiver" >
<intent-filter>
<action android:name=".AlarmManagerReceiver" />
</intent-filter>
</receiver>
<service
android:name=".AlarmManagerService"
android:enabled="true" >
<intent-filter>
<action android:name=".AlarmManagerService" />
</intent-filter>
</service>
