如何讓程式開機時就啟動

1. 先做一個BroadcastReceiver的class
public class ReceiverForStartup extends BroadcastReceiver{
     public void onReceive(Context context, Intent intent)
    {
          String action = intent.getAction();
          if(action.equals(Intent.ACTION_BOOT_COMPLETED))
         {
                 Intent i = new Intent(context, "your activity class");
                 i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                 context.startActivity(i);
         }
     }
}

2. 在AndroidManifest.xml加入
[receiver android:name=".ReceiverForStartup" android:enabled="true"
          android:permission="android.permission.RECEIVE_BOOT_COMPLETED"]
     [intent-filter]
          [action android:name="android.intent.action.BOOT_COMPLETED" /]
          [category android:name="android.intent.category.DEFAULT" /]
     [/intent-filter]
[/receiver]
