Question

这是我实现OnPrimaryCLipChangedListener的代码：

public class PrimaryClipChangedListener implements OnPrimaryClipChangedListener {

@Override
public void onPrimaryClipChanged() {
    // TODO Auto-generated method stub

        // TODO Auto-generated method stub
            Log.d("RAJATH", "copyclip reached");                    
        }

}

我注册听众的服务：

package com.example.tryservice;

import android.annotation.SuppressLint;
import android.app.Service;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Intent;
import android.content.ClipboardManager.OnPrimaryClipChangedListener;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;

@SuppressLint("NewApi")
public class MyService extends Service{
public MyService() {
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // TODO Auto-generated method stub
    Log.d("RAJATH", "Service Reached");
    ClipboardManager cb = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);       
    cb.addPrimaryClipChangedListener(new PrimaryClipChangedListener());
    return 0;
}
@Override
public IBinder onBind(Intent intent) {
    // TODO: Return the communication channel to the service.
    throw new UnsupportedOperationException("Not yet implemented");
}
}

我有一项启动此服务的活动。此代码的目的是在后台监听剪贴板更改。哪里出错了？

究竟什么不起作用？ Android 4.3中存在一个错误，如果您监听OnPrimaryClipChangedListener回调，系统会崩溃。

OnPrimaryClipChangedListener无法正常工作
