I'm using quickblox android sdk for my chat application. I know that when opponent user starts the conversation QBPrivateChatManagerListener -> chatCreated() event get fired. Below is my code. When chatCreated is fired I load the chat Fragment. In the chat fragment I have implemented the QBMessageListenerImpl interface. Problem here is that I don't get the first message from processMessage(). But I get the second message. So my question is how can I read the very first message that opponent user is sending ?
#Override
public void chatCreated(final QBPrivateChat qbPrivateChat, boolean b) {
ShowMessage("Incoming chat!!");
if(!b)
{
runOnUiThread(new Runnable() {
#Override
public void run() {
CreateNewChatForIncoming(qbPrivateChat);
}
});
}
}
public void CreateNewChatForIncoming(QBPrivateChat qbPrivateChat) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
PrivateChatFragment privateChatFragment = new PrivateChatFragment();
privateChatFragment.setOpponentuser(null);
privateChatFragment.setIncomingChat(qbPrivateChat);
HashMap<Integer, QBUser> allusers = applicationSingleton.getAllusers();
String title = allusers.get(qbPrivateChat.getParticipant()).getFullName();
if (title != null)
this.setTitle(title);
ft.replace(R.id.content_frame, privateChatFragment);
ft.commit();
}

I have created simple chatting application and it contains some ListView which handles all chat messages, but every ListView is defined in another class. I want to clear my list items from Clear Chat from an overflow menu, which is present in main activity. How can I achieve this?
Here is my main activity called WiFiServiceDiscoveryActivity:

DeviceClickListener, Handler.Callback, MessageTarget,
ConnectionInfoListener {
public static final String TAG = "wifidirectdemo";

Hey Adesh you could do this when the overflow item is clicked:
Call setListAdapter() again. This time with an empty ArrayList.
Hope it helps !
I managed to start a conference call cut it closes right after I start it with HUNG_UP cause and I got this in my log:
11-03 17:28:08.940: E/sinch-android-rtc(19101): peermediaconnection: virtual void rebrtc::SetSDPObserver::OnFailure(const string&)Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
11-03 17:28:08.940: E/sinch-android-rtc(19101): mxp: Failed to set remote answer sdp: Offer and answer descriptions m-lines are not matching. Rejecting answer.
can anybody help me solve this please?
Edit:
my scenario is when a user clicks the call button I ask him if he wants to start a new call or join an already created one.
I managed to make my code from this question (Sinch conference call error) work as my GroupService class had some bugs.
I start my call like this:
Intent intent1 = new Intent(CreateGroupCallActivity.this,SinchClientService.class);
intent1.setAction(SinchClientService.ACTION_GROUP_CALL);
String id = String.valueOf(uid) + "-" + call_id.getText().toString();
intent1.putExtra(SinchClientService.INTENT_EXTRA_ID,id);
startService(intent1);
and in my SinchClientService:
if(intent.getAction().equals(ACTION_GROUP_CALL))
{
String id = intent.getStringExtra(INTENT_EXTRA_ID);
if(id != null)
groupCall(id);
}
public void groupCall(String id) {
if (mCallClient != null) {
Call call = mCallClient.callConference(id);
CurrentCall.currentCall = call;
Log.d("call", "entered");
Intent intent = new Intent(this, GroupCallService.class);
startService(intent);
}
}

I'm working on a music player for android and i'm stuck at this problem.
By now i can play a song with musicservice and send it to background, i also display a notification with current playing song.
What i need is to re-open the main activity from the song notification and continue playing the song, it actually starts the desired activity but the music service is re-created and it stops the current playing song.

(The fragment also re-creates itself when navigating through drawer menu items)
I hope somebody can help me achieve this. I dont know how to maintane the state when re-starting the MainActivity (by the way, im using navdrawer to hold fragments)
Include the currently playing song in your notification intent. Update the intent as the song changes. Include the flag to clear top and the flag to update current in the notification intent. :( sorry IDK if I have the flags right for your situation but you'll have a place to do more research.
In your service where you create the notification intent.
// link the notifications to the recorder activity
Intent resultIntent = new Intent(context, KmlReader.class);
resultIntent
.setAction(ServiceLocationRecorder.INTENT_COM_GOSYLVESTER_BESTRIDES_LOCATION_RECORDER);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent resultPendingIntent = PendingIntent
.getActivity(context, 0, resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
return mBuilder.build();
}
Then in main onCreate check the bundle for the name of the currently playing song and display it. Notice how I check for the existence of a bundle key before using it.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
String intentaction = intent.getAction();
// First Run checks
if (savedInstanceState == null) {
// first run init
...
} else {
// get the saved_Instance state
// always get the default when key doesn't exist
// default is null for this example
currentCameraPosition = savedInstanceState
.containsKey(SAVED_INSTANCE_CAMERA_POSITION) ? (CameraPosition) savedInstanceState
.getParcelable(SAVED_INSTANCE_CAMERA_POSITION) : null;
...
I have a trouble with getting Activity(Nullpointerexception) after that I have rotate screen and received callback from AsyncTask to update my views of the fragment. If I wont change orientation then everything is OK(but not all the time, sometimes this bug appears)
My main activity:
public class MainActivity extends SherlockFragmentActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pager_layout);
fm = getSupportFragmentManager();
fm.addOnBackStackChangedListener(this);
session = new SessionManager(getApplicationContext());
if (session.isAuthorizated()) {
disableTabs();
FragmentTransaction ft = fm.beginTransaction();
if (session.termsAndConditions()) {
ft.replace(android.R.id.content, new TermsAndConditionsFragment(), "terms-and-conditions").commit();
}
}
} else {
enableTabs();
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(actionBar.newTab().setText("Log in"), LoginFragment.class, null);
mTabsAdapter.addTab(actionBar.newTab().setText("Calculator"), CalculatorFragment.class, null);
}
}
That`s my fragment:
public class TermsAndConditionsFragment extends SherlockFragment implements OnClickListener, OnTouchListener, OnEditorActionListener, ValueSelectedListener, AsyncUpdateViewsListener {
private static final String TAG = "TermsAndConditionsFragment";
private TermsAndConditionsManager termsAndConditionsM;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
prepareData();
}
public void prepareData() {
if (getSherlockActivity() == null)
Log.d(TAG, "Activity is null");
termsAndConditionsM = new TermsAndConditionsManager(getSherlockActivity().getApplicationContext());
termsAndConditions = termsAndConditionsM.getTermsAndConditions();
...
// some stuff
...
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = init(inflater, container);
return rootView;
}
private View init(LayoutInflater inflater, ViewGroup container) {
rootView = inflater.inflate(R.layout.fragment_terms_and_conditions, container, false);
//bla bla bla
return rootView;
}
public void updateTermsAndConditionsView() {
//update views here
}
#Override
public void onClick(View v) {
ft = fm.beginTransaction();
switch (v.getId()) {
case R.id.etHowMuch:
d = NumberPaymentsPickerFragment.newInstance(getSherlockActivity(), Integer.valueOf(howMuch.replace("£", "")), 0);
d.setValueSelectedListener(this);
d.show(getFragmentManager(), Const.HOW_MUCH);
break;
}
}
#Override
public void onValueSelected() {
Bundle args = new Bundle();
...
ExecuteServerTaskBackground task = new ExecuteServerTaskBackground(getSherlockActivity());
task.setAsyncUpdateViewsListener(this);
task.action = ServerAPI.GET_TERMS_AND_CONDITIONS;
task.args = args;
task.execute();
}
#Override
public void onUpdateViews() {
prepareData();
updateTermsAndConditionsView();
}
}
My AsyncTask with callback:
public class ExecuteServerTaskBackground extends AsyncTask<Void, Void, Void> {
private static final String TAG = "ExecuteServerTaskBackground";
Activity mActivity;
Context mContext;
private AsyncUpdateViewsListener callback;
public ExecuteServerTaskBackground(Activity activity) {
this.mActivity = activity;
this.mContext = activity.getApplicationContext();
}
public void setAsyncUpdateViewsListener(AsyncUpdateViewsListener listener) {
callback = listener;
}
#Override
protected Void doInBackground(Void... params) {
ServerAPI server = new ServerAPI(mContext);
if (!args.isEmpty())
msg = server.serverRequest(action, args);
else
msg = server.serverRequest(action, null);
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
callback.onUpdateViews();
}
}
Why does it behave so? How can I get activity correctly if I change orientation.
EDIT:
As I understand correctly nullpointer appears after orientation changed and asynctask executed due to wrong reference between asyctask and Activity. Recreated activity doesnt have this reference thats why when I receive callback I use wrong activity reference which isn`t exist anymore. But how can I save current activity reference?
EDIT:
I have decided to try realize my task throughout Service and that`s what I have done.

As you mention in your edit, the current Activity is destroyed and recreated on orientation change.
But how can I save current activity reference?
You shouldn't. The previous Activity is no longer valid. This will not only cause NPEs but also memory leaks because the AsyncTask might hold the reference to old Activity, maybe forever.
Solution is to use Loaders.
