When clicking the button I start a new process from the activity. I have a MAIN acticity with a single START button. I've tried a million things, but here, I've just gone back to a very basic example so I can showcase it and ask for help: I should end up with a file with 1200 lines with a timestamp per sample. I want to have a counter add +1 every second for 1200 seconds (20 minutes) and write to a file every time it counts. I'm working on a bigger project, but here I'm just trying to get a very simple example to work which I can later adapt to my project.

Since you are using AlarmManager you should be able to use the IMMUTABLE flag. You need to do this: pendingIntent = PendingIntent.getBroadcast(service, 0, new Intent(Īction), PendingIntent.FLAG_UPDATE_CURRENT | Help me to fix the issue ERROR IN ANDROID STUDIO IMAGE PendingIntent = PendingIntent.getBroadcast(service, 0, new Intent(Īction), PendingIntent.FLAG_UPDATE_CURRENT) Service.registerReceiver(alarmReceiver, new IntentFilter(action)) Log.d(TAG, 'Register alarmreceiver to MqttService'+ action) String action = MqttServiceConstants.PING_SENDER This is a place in AlarmPingSender.java where the error occurred public void start() I can’t update the pending intent flag in android studio project coding Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
