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

packagecom.test.kevin;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.util.Log;
publicclassBootBroadcastReveiverextendsBroadcastReceiver{
privatestaticfinalStringTAG="BootBroadcastReveiver";
@Override
publicvoidonReceive(Contextcontext,Intentintent){
if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
IntentbootServiceIntent=newIntent(context,MainActivity.class);
context.startService(bootServiceIntent);
Log.d(TAG,"--------Bootstartservice-------------");
}
}
}

Mainservice代码

packagecom.test.kevin;
importjava.util.Timer;
importjava.util.TimerTask;
importandroid.app.Service;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.IntentFilter;
importandroid.os.Handler;
importandroid.os.IBinder;
importandroid.os.Message;
importandroid.util.Log;
publicclassMainServiceextendsService{
privatestaticfinalStringTAG="MainService";
privatefinalintCLOSE_ALERTDIALOG=0;
privateinttimecount=0;
privateintbatteryValue=0;
@Override
publicIBinderonBind(Intentintent){
Log.d(TAG,"----onBind-----");
returnnull;
}
@Override
publicvoidonCreate(){
Log.d(TAG,"---------onCreate--------");
registerReceiver(batteryChangedReceiver,newIntentFilter(
Intent.ACTION_BATTERY_CHANGED));
delayCloseController.timer.schedule(delayCloseController,1500,1000);
}
@Override
publicintonStartCommand(Intentintent,intflags,intstartId){
//TODOAuto-generatedmethodstub
returnsuper.onStartCommand(intent,flags,startId);
}
privateBroadcastReceiverbatteryChangedReceiver=newBroadcastReceiver(){
@Override
publicvoidonReceive(Contextcontext,Intentintent){
if(Intent.ACTION_BATTERY_CHANGED.equals(intent.getAction())){
intlevel=intent.getIntExtra("level",0);
intscale=intent.getIntExtra("scale",100);
Log.d(TAG,"----------level---"+level);
Log.d(TAG,"----------scale---"+scale);
Log.d(TAG,"----------Total---"+level*100/scale+"%");
batteryValue=level*100/scale;
}
}
};
privateHandlermHandler=newHandler(){
@Override
publicvoidhandleMessage(Messagemsg){
switch(msg.what){
caseCLOSE_ALERTDIALOG:{
if(timecount%2==1){
if(batteryValue<=15){
onPowerLed();
try{
Thread.sleep(300);
}catch(InterruptedExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
offPowerLed();
Log.d(TAG,"------PowerLed------");
}
}else{
onWorkLed();
try{
Thread.sleep(300);
}catch(InterruptedExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
offWorkLed();
Log.d(TAG,"------WorkLed------");
}
}
timecount++;
break;
default:
break;
}
}
};
privateclassDelayCloseControllerextendsTimerTask{
privateTimertimer=newTimer();
@Override
publicvoidrun(){
MessagemessageFinish=newMessage();
messageFinish.what=CLOSE_ALERTDIALOG;
mHandler.sendMessage(messageFinish);
}
}
privateDelayCloseControllerdelayCloseController=newDelayCloseController();
publicvoidonPowerLed(){
Log.d(TAG,"------------onPowerLed-------------");
};
publicvoidoffPowerLed(){
Log.d(TAG,"------------offPowerLed-------------");
};
publicvoidonWorkLed(){
Log.d(TAG,"------------onWorkLed-------------");
};
publicvoidoffWorkLed(){
Log.d(TAG,"------------offWorkLed-------------");
};
}

Androidmanifest.xml代码

<?xmlversion="1.0"encoding="utf-8"?>
<manifestxmlns:android="http://schemas.android.com/apk/res/android"
package="com.test.kevin"android:versionCode="1"android:versionName="1.0">
<applicationandroid:icon="@drawable/icon"android:label="@string/app_name">
<serviceandroid:name=".MainService"/>
<receiverandroid:name=".BootBroadcastReveiver">
<intent-filter>
<actionandroid:name="android.intent.action.BOOT_COMPLETED"></action>
<categoryandroid:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</receiver>
</application>
<uses-permissionandroid:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
</manifest>

把以上代码一个小小Service实例，重启机子后可以直接远行.
