我尝试了以下创建和使用BoundService的示例:https://developer.android.com/guide/components/bound-services#Binder 问题是,它无法为我连接到服务。我有一个已经存在的项目,里面有一些片段,但如果这会把事情搞砸,我也会复制它。这是我的MainActivity.kt: import android.content.ComponentName import android.content.Co...
當它要觸發檔案下載時,它直接呼叫 DownloadBoundService.startDownload() 即可。然後在 onStop() 中呼叫 unbindService()。如果是 Background Service 的話,那就要呼叫 startCommand() 來觸發檔案下載。相較之下,就比較不那麼地方便。 package com.waynestalk.androidboundserviceexample import android.app.Service ...
Although you should usually implement eitheronBind()oronStartCommand(), it's sometimes necessary to implement both. For example, a music player might find it useful to allow its service to run indefinitely and also provide binding. This way, an activity can start the service to play some mus...

Android Service总结04 之被绑定的服务 -- Bound Service 1 Bound Service说明 Bound Service,即被绑定的服务,和Started Service一样,它也是2种常见服务之一。它常被用在执行进程的某个后台操作或进程间通讯(IPC)。 实现步骤和使用方法 (01) 创建一个Bound Service类,该类要继承于Service。
example.aidlserver; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; import androidx.annotation.Nullable; public class MyService extends Service { private static final String TAG = "MyService"...
// Unbind from the service if (mBound) { unbindService(mConnection); mBound = false; } } /** Called when a button is clicked (the button in the layout file attaches to * this method with the android:onClick attribute) */ public void onButtonClick(View v) { ...
package com.example.android; // Declare any non-de;fault types here with import statements /** Example service interface */ interface IRemoteService { /** Request the process ID of this service, to do evil things with it. */ int getPid(); ...
AIDL(Android接口定义语言)执行把对象分解为操作系统能够理解并能跨进程封送的基本体以执行IPC的所有的工作.上面所讲的使用一个Messenger,实际上就是基于AIDL的.就像上面提到的,Messenger在一个线程中创建一个容纳所有客户端请求的队列,使用service一个时刻只接收一个请求.然而,如果你想要你的service同时处理多个请求,那么...
For example, here's a service that provides clients access to methods in the service through aBinder implementation: public class LocalService extends Service { // Binder given to clients private final IBinder mBinder = new LocalBinder(); // Random number generator private final...
