I'm trying to create an alarm Manager that sends notification every 24 hours at specific time consulted other Stackoverflow code. I tried this code below but onReceive()
never gets executed. What i'm doing wrong?
private var HOUR_TO_SHOW_PUSH = 21
private var MINUTE_TO_SHOW_PUSH = 0
private val REQUEST_CODE = 100
private lateinit var alarmManager: AlarmManager
private lateinit var pendingIntent: PendingIntent
class MainActivity : AppCompatActivity() {
...
alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
val intent = Intent(this, AlertReceiver::class.java)
pendingIntent = PendingIntent.getBroadcast(this, REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT)
val calendar = GregorianCalendar.getInstance().apply {
if (get(Calendar.HOUR_OF_DAY) >= HOUR_TO_SHOW_PUSH) {
add(Calendar.DAY_OF_MONTH, 1)
}
set(Calendar.HOUR_OF_DAY, HOUR_TO_SHOW_PUSH)
set(Calendar.MINUTE, 0)
set(Calendar.SECOND, 0)
set(Calendar.MILLISECOND, 0)
}
alarmManager.setRepeating(
AlarmManager.RTC_WAKEUP,
calendar.timeInMillis,
AlarmManager.INTERVAL_DAY,
pendingIntent
)
AlertReceiver
class AlertReceiver: BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
override fun onReceive(context: Context?, intent: Intent?) {
Toast.makeText(context, "Alarm", Toast.LENGTH_LONG).show()
println("Alarm")
Log.e("Alarm","Alarm Triggered")
}
Manifest
<receiver
android:name=".AlertReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.LOCKED_BOOT_COMPLETED" />
<action android:name="MyBroadcastReceiverAction"/>
</intent-filter
</receiver>

Normally you would register your receiver in the AndroidManifest
like this:
<receiver android:name=".MyBroadcastReceiver" android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.INPUT_METHOD_CHANGED" />
</intent-filter>
</receiver>

it depends on the battery optimization applied to the app by the device, it varies from a device manufacturer to other
Normally you will find it in Settings > Apps > "your app name" > Battery Saver
Set it to No Restrictions
