Listen for the ACTION BOOT COMPLETE and do what you need to from there   There is a code snippet here   Update   Original link on answer is down  so based on the comments  here it is linked code  because no one would ever miss the code when the links are down   In AndroidManifest xml  application-part     lt receiver android enabled  true  android name   BootUpReceiver          android permission  android permission RECEIVE BOOT COMPLETED  gt            lt intent-filter gt                   lt action android name  android intent action BOOT COMPLETED    gt                   lt category android name  android intent category DEFAULT    gt           lt  intent-filter gt   lt  receiver gt          lt uses-permission android name  android permission RECEIVE BOOT COMPLETED    gt         public class BootUpReceiver extends BroadcastReceiver            Override         public void onReceive Context context  Intent intent                    Intent i   new Intent context  MyActivity class      MyActivity can be anything which you want to start on bootup                    i addFlags Intent FLAG ACTIVITY NEW TASK                   context startActivity i                    Source  https   web archive org web 20150520124552 http   www androidsnippets com autostart-an-application-at-bootup

First  you need the permission in your AndroidManifest xml    lt uses-permission android name  android permission RECEIVE BOOT COMPLETED    gt    Also  in yourAndroidManifest xml  define your service and listen for the BOOT COMPLETED action    lt service android name   MyService  android label  My Service  gt       lt intent-filter gt           lt action android name  com myapp MyService    gt       lt  intent-filter gt   lt  service gt    lt receiver     android name   receiver StartMyServiceAtBootReceiver      android label  StartMyServiceAtBootReceiver  gt       lt intent-filter gt           lt action android name  android intent action BOOT COMPLETED    gt       lt  intent-filter gt   lt  receiver gt    Then you need to define the receiver that will get the BOOT COMPLETED action and start your service   public class StartMyServiceAtBootReceiver extends BroadcastReceiver         Override     public void onReceive Context context  Intent intent            if  Intent ACTION BOOT COMPLETED equals intent getAction                   Intent serviceIntent   new Intent context  MyService class               context startService serviceIntent                       And now your service should be running when the phone starts up

The Sean s solution didn t work for me initially  Android 4 2 2   I had to add a dummy activity to the same Android project and run the activity manually on the device at least once  Then the Sean s solution started to work and the BroadcastReceiver was notified after subsequent reboots

Another approach is to use android intent action USER PRESENT instead of android intent action BOOT COMPLETED to avoid slow downs during the boot process  But this is only true if the user has enabled the lock Screen - otherwise this intent is never broadcasted   Reference blog -  The Problem With Android   s ACTION USER PRESENT Intent

This is how to make an activity start running after android device reboot   Insert this code in your AndroidManifest xml file  within the  lt application gt  element  not within the  lt activity gt  element     lt uses-permission android name  android permission RECEIVE BOOT COMPLETED    gt    lt receiver     android enabled  true      android exported  true       android name  yourpackage yourActivityRunOnStartup      android permission  android permission RECEIVE BOOT COMPLETED  gt        lt intent-filter gt           lt action android name  android intent action BOOT COMPLETED    gt           lt action android name  android intent action QUICKBOOT POWERON    gt           lt category android name  android intent category DEFAULT    gt       lt  intent-filter gt    lt  receiver gt    Then create a new class yourActivityRunOnStartup  matching the android name specified for the  lt receiver gt  element in the manifest    package yourpackage   import android content BroadcastReceiver  import android content Context  import android content Intent   public class yourActivityRunOnStartup extends BroadcastReceiver         Override     public void onReceive Context context  Intent intent            if  intent getAction   equals Intent ACTION BOOT COMPLETED                 Intent i   new Intent context  MainActivity class               i addFlags Intent FLAG ACTIVITY NEW TASK               context startActivity i                        Note  The call i addFlags Intent FLAG ACTIVITY NEW TASK   is important because the activity is launched from a context outside the activity  Without this  the activity will not start   Also  the values android enabled  android exported and android permission in the  lt receiver gt  tag do not seem mandatory  The app receives the event without these values  See the example here
