在我通过调用绑定服务之后:

bindService(new Intent(IBumpAPI.class.getName()), connection, Context.BIND_AUTO_CREATE);

我需要出于调试目的来调用 onServiceDisconnected() 。

我知道 Android 系统会在与服务的连接意外丢失时调用它,例如当服务崩溃或被终止时,并且在客户端解除绑定时不会调用它。

所以我的问题是如何强制 onServiceDisconnected() 在我想要的时候被调用,以便我可以完成测试?

您需要启动服务,然后使用 Context.BIND_NOT_FOREGROUND 标志绑定,然后停止它。这将导致 onServiceDisconnected 被调用。这是 MainActivity 的代码(假设您定义了 TestService 服务),其中两个按钮链接到调用 doBind 和 doUnbind 方法:

package com.example.servicetest;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {
    private static final String TAG = "MainActivity";

    private ServiceConnection connection = new ServiceConnection() {

        @Override
        public void onServiceDisconnected(ComponentName name) {
            Log.d(TAG, "Service disconnected: " + name);
        }

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.d(TAG, "Service connected: " + name);
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    public void doBind(View v) {
        Intent i = new Intent(this, TestService.class);
        startService(i);
        bindService(i, connection, Context.BIND_NOT_FOREGROUND);
    }

    public void doUnbind(View v) {
        Intent i = new Intent(this, TestService.class);
        stopService(i);
    }

}

当您单击按钮时,此代码提供以下日志:

11-27 09:21:57.326: D/MainActivity(10724): Service connected: ComponentInfo{com.example.servicetest/com.example.servicetest.TestService}
11-27 09:21:58.099: D/MainActivity(10724): Service disconnected: ComponentInfo{com.example.servicetest/com.example.servicetest.TestService}

您可能只是取消绑定您的服务

public void openService {
mConnection = new ServiceConnection() {
            @Override
            public void onServiceConnected(ComponentName name, IBinder service) {
                mService = IService.Stub.asInterface(service);
            }
            @Override
            public void onServiceDisconnected(ComponentName cn) {
                mService = null;
            }
        };
         bindService(service, mConnection, Context.BIND_AUTO_CREATE);   
    }
}

public void closeService() {
    unbindService(mConnection);
    stopService(new Intent(this, Service.class));
}
