[英]BroadcastReceiver inside activity not receiving broadcasts from service
[英]BroadcastReceiver not receiving Intent from inside Service
我的應用程序中有一個“活動”和“服務”,我正在彼此之間發送廣播。 當我的活動接收到從我的服務發送的廣播時,我的服務沒有收到我的活動發送的廣播。
這是我的一些代碼:
活動
@Override
public void onResume()
{
Log.i(TAG, "in onResume");
IntentFilter messageFilter = new IntentFilter(Constants.MESSAGE);
messageReceiver receiver = new messageReceiver();
registerReceiver(receiver, messageFilter);
startService(new Intent(this, Server.class));
super.onResume();
}
public class messageReceiver extends BroadcastReceiver
{
@Override
public void onReceive (Context context, Intent intent)
{
Log.i(TAG, "in messageReceiver");
serverStatus.setText(intent.getStringExtra(Constants.MESSAGE));
}
}
@SuppressLint("ParserError")
public OnClickListener btnSendClicked = new OnClickListener() {
public void onClick(View v) {
Log.i(TAG, "btnSend clicked");
// This broadcast is NOT picked up by my Service
Intent sendClicked = new Intent(Constants.SEND_CLICKED);
sendBroadcast(sendClicked);
}
};
服務
@SuppressLint({ "ParserError", "ParserError", "ParserError" })
public class btnSendClickedReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context arg0, Intent arg1) {
// Do some stuff
}
};
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Log.i(TAG, "in onStartCommand");
SERVERIP = getLocalIpAddress();
IntentFilter sendClickedFilter = new IntentFilter(Constants.SEND_CLICKED);
btnSendClickedReceiver receiver = new btnSendClickedReceiver();
registerReceiver(receiver, sendClickedFilter);
runServer();
return START_STICKY;
}
@SuppressLint("ParserError")
public void runServer()
{
try
{
if (SERVERIP != null)
{
Log.i(TAG, "inside runServer");
// This broadcast is picked up by my activity:
Intent intent = new Intent(Constants.MESSAGE);
intent.putExtra(Constants.MESSAGE, "Listening on IP: " + SERVERIP);
sendBroadcast(intent);
serverSocket = new ServerSocket(SERVERPORT);
while (true)
{
client = serverSocket.accept();
Log.i(TAG, "connected");
Intent connectedIntent = new Intent(Constants.MESSAGE);
connectedIntent.putExtra(Constants.MESSAGE, "Connected");
sendBroadcast(connectedIntent);
}
}
else
{
// no internet connection
}
} catch (Exception e)
{
//Error
e.printStackTrace();
}
}
表現
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="message"/>
<action android:name="SendClicked"/>
</intent-filter>
</activity>
<service android:name=".Server" android:process=":remote">
</service>
我已經嘗試調試了好幾天,但是我不確定是什么問題。 任何幫助表示贊賞。
尚未在androidManifest.xml文件中輸入BroadCast接收器條目,請添加以上條目並嘗試。
我遇到過同樣的問題。 我拿出:remote說明符,然后它起作用了。 我不知道為什么會有所不同。 而且我也從未在清單中指定接收者。
