BroadcastReceiver receives events with delay after reboot

Question

I try to receive PHONE_STATE intents with next BroadcastReceiver

<receiver android:name=".CallReceiver"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

But after rebooting my Nexus 5X and making the call to this device, ringing events can be received after the call has been already finished a minute ago. How can I fix it? Any ideas?

Answer 1

According to CommonsWare in this answer-

There are many, many apps that want to get control at boot time. How quickly yours will get its turn will depend on many variables, such as the number of installed apps, the CPU speed of the device, the amount of system RAM on the device, etc.

Also, starting an activity from a BroadcastReceiver at boot time is fairly evil. If you want to be the first thing the user sees after a reboot, write a home screen implementation.

All you can do is give priority like this -

 <action android:name="android.intent.action.BOOT_COMPLETED" android:priority="999"/>

Answer 2

this because there any other Receiver listen to this broadcast, you can try to improve you Recevier' priority just like that

<intent-filter android:priority="2147483647">  
<action android:name="android.intent.action.BOOT_COMPLETED" />  
</intent-filter>
