我有一个非常基本的服务程序,但我收到这条警告消息
02-11 04:58:23.383: E/ActivityThread(1686): Activity com.example.serviceexample.Client has leaked ServiceConnection com.example.serviceexample.Client$1@416e56e8 that was originally bound here

代码部分:
public class Client extends Activity {
boolean mBounded;
Server mServer;
TextView text;
Button button;
LocalBinder mLocalBinder;
ServiceConnection mConnection = new ServiceConnection() {
public void onServiceDisconnected(ComponentName name) {
Toast.makeText(Client.this, "Service is disconnected", 1000).show();
mBounded = false;
mServer = null;
}
public void onServiceConnected(ComponentName name, IBinder service) {
Toast.makeText(Client.this, "Service is connected", 1000).show();
mBounded = true;
LocalBinder mLocalBinder = (LocalBinder)service;
mServer = mLocalBinder.getServerInstance();
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Toast.makeText(this, "onCreate Called", Toast.LENGTH_SHORT).show();
setContentView(R.layout.activity_main);
text = (TextView)findViewById(R.id.text);
button = (Button) findViewById(R.id.button);
mServer = new Server();
// mServer = mLocalBinder.getServerInstance();
try{
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try{
text.setText(mServer.getTime());
}
catch(Exception e)
{e.printStackTrace();}
}
});
}
catch(Exception e)
{e.printStackTrace();}
}
@Override
protected void onStart() {
super.onStart();
Toast.makeText(this, "onStart Called", Toast.LENGTH_SHORT).show();
Intent mIntent = new Intent(this, Server.class);
bindService(mIntent, mConnection,BIND_ADJUST_WITH_ACTIVITY);// BIND_AUTO_CREATE);// This is Line 72
};
@Override
protected void onStop() {
super.onStop();
if(mBounded) {
unbindService(mConnection);
mBounded = false;
Toast.makeText(this, "onStop Called", Toast.LENGTH_SHORT).show();
}
}
protected void onDestroy()
{
super.onDestroy();
Toast.makeText(this, "onStop Called", Toast.LENGTH_SHORT).show();
if(mBounded) {
unbindService(mConnection);
mBounded = false;
Toast.makeText(this, "onStop Called", Toast.LENGTH_SHORT).show();
}
}
}
服务器类:
public class Server extends Service{
IBinder mBinder = new LocalBinder();
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
public class LocalBinder extends Binder {
public Server getServerInstance() {
return Server.this;
}
}
public String getTime() {
SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
return mDateFormat.format(new Date());
}
}
请告诉我如何解决此 logcat 消息。我可以在第 72 行看到一些问题。但我不知道如何解决。请帮忙。
最佳答案
您还没有解绑您的服务。服务连接泄漏仅在您忘记停止或取消绑定(bind)服务时发生。
查看您的代码..当您尝试取消绑定(bind)服务时,您的 mBounded
为假,因为您在 serviceconnection 接口(interface)的 servicedisconnected 方法中将其设置为假,这会阻碍您取消绑定(bind)服务。
在这里看看你做了什么:
public void onServiceDisconnected(ComponentName name) {
Toast.makeText(Client.this, "Service is disconnected", 1000).show();
mBounded = false;//here you make false to the boolean variable which make obstacle to unbind your service
mServer = null; }
从这里删除mBounded = false;
您必须了解 connection disconnected() 与 Service unbind() 不同。
绑定(bind)服务时必须使其为真。即:
Intent mIntent = new Intent(this, Server.class);
bindService(mIntent, mConnection,Context.BIND_AUTO_CREATE);
mBound = true;
并且在取消绑定(bind)服务后使 bool 变量 false 不在 serviceconnection.like 中:
if(mBound){
unbindService(mConnection);
mBounded = false;
}
它会解决你的问题..
