无法完成在Android的引导侦听器后 [英] Can't complete After Boot listener in Android
本文介绍了无法完成在Android的引导侦听器后的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我能不尽快启动服务的设备启动。
我的服务和接收器类如下。
包android_programmers_guide.BroadcastReceiver1;
进口的java.util.ArrayList;
进口的java.util.List;
进口java.util.Timer中;
进口java.util.TimerTask中;
进口android.app.ActivityManager;
进口android.app.Service;
进口android.content.Intent;
进口android.content.pm.PackageManager;
进口android.os.IBinder;
进口android.util.Log;
进口android.widget.Toast;
公共类为MyService扩展服务{
/ **
*延迟,直到日志任务的第一exeution。
* /
私人最终长mDelay = 0;
/ **
*日志的任务期。
* /
私人最终长mPeriod = 500;
/ **
*登录标签使用该服务。
* /
私人最终字符串LOGTAG =** ** BootDemoService;
/ **
*定时调度服务。
* /
私人定时器mTimer; / **
*定时任务的实现。
* /
私有类LogTask扩展的TimerTask {
公共无效的run(){
Log.i(LOGTAG计划);
}
}
私人LogTask mLogTask; @覆盖
公众的IBinder onBind(最终意向意图){
返回null;
} @覆盖
公共无效的onCreate(){
super.onCreate();
Log.i(LOGTAG,创造);
mTimer =新的Timer();
mLogTask =新LogTask();
} @覆盖
公共无效调用onStart(最终意图的意图,最终诠释startId){
super.onStart(意向,startId);
Log.i(LOGTAG,启动);
mTimer.schedule(mLogTask,mDelay,mPeriod);
}
}
这是接收器类。
包android_programmers_guide.BroadcastReceiver1;
进口android.content.BroadcastReceiver;
进口android.content.Context;
进口android.content.Intent;
公共类MyStartupIntentReceiver扩展广播接收器{
@覆盖
公共无效的onReceive(最终上下文的背景下,最终的意图bootintent){
意图mServiceIntent =新的Intent();
mServiceIntent.setAction(android_programmers_guide.BroadcastReceiver1.MyService);
context.startService(mServiceIntent);
}
}
这是清单文件。
<?XML版本=1.0编码=UTF-8&GT?;
<清单的xmlns:机器人=http://schemas.android.com/apk/res/android

请尽快回复,并在此先感谢。
干杯!
PS:我只从一个教程复制code和我使用Android的姜饼和Eclipse伽利略
。编辑为你们说,我的服务是成功的。
但还有一个问题。
我无法启动的活动。我的code是如下:
公共无效在onStart(最终意图的意图,最终诠释startId)
{
super.onStart(意向,startId);
意图intent1 =新的Intent();
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent1);
}
解决方案
请添加该行的清单。
<使用许可权的android:NAME =android.permission.RECEIVE_BOOT_COMPLETED>< /使用许可权>
修改后:
公共无效的onReceive(上下文的背景下,意图意图){
// TODO自动生成方法存根
如果(android.intent.action.BOOT_COMPLETED.equals(intent.getAction())){
意图pushIntent =新意图(背景下,MyService.class);
context.startService(pushIntent); } }
I can't start a service as soon as device boots. My service and receiver classes are as follows.
package android_programmers_guide.BroadcastReceiver1;
import java.util.ArrayList;
import java.util.List;
import java.util.Timer;
import java.util.TimerTask;
import android.app.ActivityManager;
import android.app.Service;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class MyService extends Service {
/**
* Delay until first exeution of the Log task.
*/
private final long mDelay = 0;
/**
* Period of the Log task.
*/
private final long mPeriod = 500;
/**
* Log tag for this service.
*/
private final String LOGTAG = "**BootDemoService**";
/**
* Timer to schedule the service.
*/
private Timer mTimer;
/**
* Implementation of the timer task.
*/
private class LogTask extends TimerTask {
public void run() {
Log.i(LOGTAG, "scheduled");
}
}
private LogTask mLogTask;
@Override
public IBinder onBind(final Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
Log.i(LOGTAG, "created");
mTimer = new Timer();
mLogTask = new LogTask();
}
@Override
public void onStart(final Intent intent, final int startId) {
super.onStart(intent, startId);
Log.i(LOGTAG, "started");
mTimer.schedule(mLogTask, mDelay, mPeriod);
}
}
This is receiver class.
package android_programmers_guide.BroadcastReceiver1;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyStartupIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, final Intent bootintent) {
Intent mServiceIntent = new Intent();
mServiceIntent.setAction("android_programmers_guide.BroadcastReceiver1.MyService");
context.startService(mServiceIntent);
}
}
And this is manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="android_programmers_guide.BroadcastReceiver1"
android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<service android:name=".MyService">
<intent-filter>
<action android:name="android_programmers_guide.BroadcastReceiver1.MyService">
</action>
</intent-filter>
</service>
<receiver android:name=".MyStartIntentReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED">
</action>
</intent-filter>
</receiver>
</application>
<uses-sdk android:minSdkVersion="4" />
Please reply ASAP and thanks in advance. Cheers!
PS: I only copy code from a tutorial and I am using Android Gingerbread with Eclipse Galileo.
After editing as you guys told, my service is succeed. But there's still a problem. I can't start an activity. My code is as follows:
public void onStart(final Intent intent, final int startId)
{
super.onStart(intent, startId);
Intent intent1 = new Intent();
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent1);
}
解决方案
Please add that line in manifest.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
After Edit:
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent pushIntent = new Intent(context,MyService.class);
context.startService(pushIntent);
}
}
