Android 实例展现如何不同程序间的Serivce调用

核心提示：@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {Log.d("ReadActivity", "onServiceConnected");dsb = IDemoService

@Override

public void onServiceConnected(ComponentName name, IBinder service) {

Log.d("ReadActivity", "onServiceConnected");

dsb = IDemoServiceBinder.Stub.asInterface(service);

}

@Override

public void onServiceDisconnected(ComponentName name) {

dsb = null;

}

};

绑定一个服务使用的代码

Intent s = new Intent("com.shinestudio.demo.demoservice");

bindService(s, sc, Context.BIND_AUTO_CREATE);

解绑

unbindService(sc);

使用接口中的方法，因为使用aidl的方法是异步的，最好不要绑定完就使用，而且在使用前一定要判断，防止NullPointerException。而且aidl方法会抛出异常，请处理异常。

if (dsb != null) {

try {

tv.setText(dsb.getPushString());

} catch (RemoteException e) {

e.printStackTrace();

}

}

项目完整的代码 接上文

DemoService

package com.shinestudio.demo.service;

import android.app.Notification;

import android.app.NotificationManager;

import android.app.PendingIntent;

import android.app.Service;

import android.content.Intent;

import android.os.Bundle;

import android.os.IBinder;

import android.os.RemoteException;

import android.util.Log;

public class DemoService extends Service {

private int data = 0;

private String pushData1;

private String pushData2;

private NotificationManager nm;

private IDemoServiceBinder.Stub dBinder = new IDemoServiceBinder.Stub() {

@Override

public String getPushString() throws RemoteException {

return pushData1;

}

@Override

public void setPushString(String str) throws RemoteException {

pushData1 = str;
