android开机启动一个Service研究一下其实也蛮简单，下面直接看代码吧。

Bootbroadcastreveiver代码收藏代码
  1. packagecom.test.kevin;
  4. importandroid.content.BroadcastReceiver;
  5. importandroid.content.Context;
  6. importandroid.content.Intent;
  7. importandroid.util.Log;
  9. publicclassBootBroadcastReveiverextendsBroadcastReceiver{
  10. privatestaticfinalStringTAG="BootBroadcastReveiver";
  12. @Override
  13. publicvoidonReceive(Contextcontext,Intentintent){
  14. if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
  15. IntentbootServiceIntent=newIntent(context,MainActivity.class);
  16. context.startService(bootServiceIntent);
  17. Log.d(TAG,"--------Bootstartservice-------------");
  18. }
  19. }
  20. }

Mainservice代码收藏代码
  1. packagecom.test.kevin;

  33. }
  35. @Override
  36. publicintonStartCommand(Intentintent,intflags,intstartId){
  37. //TODOAuto-generatedmethodstub
  38. returnsuper.onStartCommand(intent,flags,startId);
  39. }
  41. privateBroadcastReceiverbatteryChangedReceiver=newBroadcastReceiver(){
  42. @Override
  43. publicvoidonReceive(Contextcontext,Intentintent){
  45. if(Intent.ACTION_BATTERY_CHANGED.equals(intent.getAction())){
  46. intlevel=intent.getIntExtra("level",0);
  47. intscale=intent.getIntExtra("scale",100);
  48. Log.d(TAG,"----------level---"+level);
  49. Log.d(TAG,"----------scale---"+scale);
  50. Log.d(TAG,"----------Total---"+level*100/scale+"%");
  51. batteryValue=level*100/scale;
  52. }
  53. }
  55. };
  57. privateHandlermHandler=newHandler(){
  58. @Override
  59. publicvoidhandleMessage(Messagemsg){
  60. switch(msg.what){
  61. caseCLOSE_ALERTDIALOG:{
  62. if(timecount%2==1){
  63. if(batteryValue<=15){
  64. onPowerLed();
  65. try{

  85. }
  86. timecount++;
  87. break;
  88. default:
  89. break;
  90. }
  91. }
  92. };
  94. privateclassDelayCloseControllerextendsTimerTask{
  95. privateTimertimer=newTimer();
  97. @Override

  102. }
  103. }

  122. };
  124. }

Androidmanifest.xml代码收藏代码
  1. <?xmlversion="1.0"encoding="utf-8"?>
  2. <manifestxmlns:android="http://schemas.android.com/apk/res/android"
  3. package="com.test.kevin"android:versionCode="1"android:versionName="1.0">
  6. <applicationandroid:icon="@drawable/icon"android:label="@string/app_name">
  7. <serviceandroid:name=".MainService"/>
  9. <receiverandroid:name=".BootBroadcastReveiver">
  10. <intent-filter>
  11. <actionandroid:name="android.intent.action.BOOT_COMPLETED"></action>
  12. <categoryandroid:name="android.intent.category.LAUNCHER"/>
  13. </intent-filter>
  14. </receiver>
  16. </application>
  17. <uses-permissionandroid:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
  18. </manifest>

把以上代码一个小小Service实例，重启机子后可以直接远行.
