BOOT_COMPLETED not working Android

Some new tablets and android devices have a security application by default. Sometimes these apps block your auto-start mode. An example of these secure apps is MyAsus manager. In this case, the user needs to add "allow auto start" inside the app manager for all the apps that want to receive this BOOT_COMPLETED

And for Htc devices add com.htc.intent.action.QUICKBOOT_POWERON

    <receiver android:enabled="true" android:name=".receivers.BootUpReceiver">
        <intent-filter>
            <category android:name="android.intent.category.DEFAULT" />
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
            <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
            <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
         </intent-filter>
    </receiver>

This below thing worked for me

AndroidManifest.xml

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<application>    

    <receiver android:name=".BootCompletedReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>

    <service android:name="NotifyingDailyService" >
    </service>

BootCompletedReceiver.class

public class BootCompletedReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent arg1) {
    // TODO Auto-generated method stub
    Log.w("boot_broadcast_poc", "starting service...");
    context.startService(new Intent(context, NotifyingDailyService.class));
}

}

Service.class

 public class NotifyingDailyService extends Service {

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int onStartCommand(Intent pIntent, int flags, int startId) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "NotifyingDailyService", Toast.LENGTH_LONG).show();
    Log.i("com.example.bootbroadcastpoc","NotifyingDailyService");

    return super.onStartCommand(pIntent, flags, startId);
}
}

This is an old and basic question but a lot of Android developers now still confused about this trouble, because THEY DON'T TAKE TIME TO READ THE DOCS CAREFULLY

I saw someone shared some links and said that: "This won't work anymore", it's totally wrong and misunderstood.

About this concern: "I've seen this answer said BOOT_COMPLETED is not sent to the application unless the user launches your application first, after Android version 3.1", please read these lines (from official docs: https://developer.android.com/about/versions/android-3.1.html#launchcontrols) to understand correctly:

• Note that an application's stopped state is not the same as an Activity's stopped state. The system manages those two stopped states separately.

• Applications are in a stopped state when they are first installed but are not yet launched and when they are manually stopped by the user (in Manage Applications). (They mean force stop an app)

1. That means a user should launch app at least once after installation to activate the application, then the app can receive implicit broadcasts from OS as normal. (Just only one time launching ever !)

2. "Does any app that gets installed and never open even only one time ever ?", yep, it 's spam and scam apps, this technique helps user to prevent that!

FURTHERMORE, UNTIL NOW (Android Oreo 8.0), when Android limits registering implicit broadcasts at Manifest (https://developer.android.com/about/versions/oreo/background.html#broadcasts), several broadcasts are still currently exempted from these limitations. And BOOT_COMPLETED is the first one they mention ! (https://developer.android.com/guide/components/broadcast-exceptions.html)

By the way, this is the best solution I found for this question:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

<receiver android:name=".BootReceiver" android:enabled="true" android:exported="true">
            <intent-filter>
                <category android:name="android.intent.category.DEFAULT"/>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
                <!--For HTC devices-->
                <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
            </intent-filter>
        </receiver>

Finally, please read the document carefully and Think twice code once :3!
