如何开始（和绑定）远程服务机器人是在另一个应用程序（不同的包中）实现的？ [英] how do i start (and bind) a remote service in android that is implemented in another app (different package)?

问题描述

我有点坚持与Android的远程服务。事情是我在包abc的实现的远程服务，我想其他应用程序能够访问该服务。我摆脱了整个蹩脚AIDL-的东西，设计通过广播意图工作，服务的接口。正常工作为止...

i'm a bit stuck with remote services in android. thing is i implemented a remote service in package "a.b.c" and i want other applications to be able to access this service. i got rid of the whole crappy aidl-stuff and designed the "interface" of the service to work via broadcasted intents. works fine so far...

问题是：我如何获得不同的应用程序（不同的包装，不同的项目，甚至不同的开发商，...）来启动/停止该服务？

problem is: how do i get a different application (different package, different project, maybe even a different developer, ...) to start/stop the service?

package d.e.f;

import a.b.c.*;

public class main extends Activity {
    protected ImyService myService;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Intent intent = new Intent(ImyService.class.getName());
        bindService(intent, sConnection, Context.BIND_AUTO_CREATE);
    }

    protected ServiceConnection sConnection = new ServiceConnection() {
        public void onServiceConnected(ComponentName className, IBinder binder) {
            wlService = ImyService.Stub.asInterface(binder);
            ServiceConnected = true;
            Toast.makeText(main.this, "service connected", Toast.LENGTH_SHORT).show();
        }

        public void onServiceDisconnected(ComponentName className) {
            wlService = null;
            ServiceConnected = false;
            Toast.makeText(main.this, "service disconnected", Toast.LENGTH_SHORT).show();
        }
    };
}

这将立即启动时崩溃我的应用程序。我做了什么错？我将如何得到这个工作？

this will crash my app immediately on startup. what did i do wrong? how will i get this to work?

一旦它的运行，命令和数据将通过广播传递。所以这应该是没有真正的问题...

once it's running, commands and data will be passed via broadcasts. so that should be no real problem...

推荐答案

第1步：建立一个＆LT;意向滤光器＆gt; 您＆LT;服务＆GT; 与＆lt;作用＆GT; 字符串

Step #1: Set up an <intent-filter> for your <service> with an <action> string.

步骤＃2：使用该操作字符串意图您使用bindService（）（如新意图（this.is.my.custom.ACTION））

Step #2: Use that action string for the Intent you use with bindService() (e.g., new Intent("this.is.my.custom.ACTION"))
