Android activity/service 开机启动

1. 在AndroidManifest.xml中添加权限和监听的intent.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.oms.netwapswitch"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".NetWapSwitch" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".WapBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>

</manifest>

注意receiver的位置，不在application中不起作用。

2. Activity

package com.oms.netwapswitch;

import android.os.Bundle;
import android.preference.PreferenceActivity;

public class NetWapSwitch extends PreferenceActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.waplink);
}
}

3. 继承类BroadcastReciver写一个接收开机完成的类

package com.oms.netwapswitch;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class WapBroadcastReceiver extends BroadcastReceiver{
private String TAG = "NetWapSwitch";
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals("android.intent.action.BOOT_COMPLETED")) {
Log.d(TAG, "Start *****************************");
Log.d(TAG, "Start *****************************");
Log.d(TAG, "Start *****************************");
Intent newIntent = new Intent(context, NetWapSwitch.class);
//newIntent.setAction("android.intent.action.MAIN");
//newIntent.addCategory("android.intent.category.LAUNCHER");
newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
}
}
}

注意:得有TASK flag.

如果是service

Intent service = new Intent(MyService.ACTION_START);
service.setClass(context, MyService.class);
context.startService(service);

这样开机完成后就会启动此应用。
