i am coding an android app. The app begins at the main screen then click the button to go the activity. My code does not have any error and build fine. However launching the app and click the button result in a crash.

These are some of the mistakes I can spot from the information you have given. Post the logcat exception details so that I can refine on this solution.
1) Don't use your own version of onCreate (in bluetoothactivity). An activity should have only one onCreate method. You also need to add the #Override prefix to the onCreate method. The code you have contains onCreate2 and onCreate3 methods which are erroneous. That may be the reason for the crash, since when the bluetooth activity is called, it can't find the onCreate method.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Keep your bluetooth related functionality here.
}
2) When launching your intent, you need to specify the source and the destination too.
Intent intent = new Intent(CallingActivity.this,CalledActivity.class);
startActivity(intent);
Your crash maybe caused due to your intent,in activity
Intent intent = new Intent("com.example.androidbtcontrol.bluetoothconnect");
startActivity(intent);
the right way
Intent intent=new Intent(firstactivity.this,secondactivity.class);
startactivity(intent);
you need to specify the destination
I've created a Textview with a null value and button in my my Mainactivity and fetched some data from sql database server using AsyncTask method on button click and stored in to my textview. Then I called an intent to another activity activity2 to show something and I returned to my Mainactivity using intent.But I can't view the previously set data in textview. It shows null value.I want to set it previously fetched data.how can I set that?

super.onCreate(savedInstanceState);

public void onClick(View v) {

}
Log.d("status", String.valueOf(status));
return status;
}
}
Whenever you wish to go to previous screen, Always finish the Activity that is on top. Here in your case, You are always creating new instance of MainActivity and this is the reason for getting null when you go back. Try using this in your StatusUpdate.java.
visited.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Visit vt= new Visit();
vt.execute();
StatusUpdate.this.finish();
}
});
notvisited.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
NotVisit n = new NotVisit();
n.execute();
StatusUpdate.this.finish();
}
});
You can store the retrieved text in a static field of your activity class, but it's better save and restore it on activity recreation.So modify your activity like:
#Override
public void onCreate(Bundle b) {
// activity initialization
// textView = ...
if (b != null) {
textView.setText(b.getString("dbtext"));
}
}
and
#Override
protected void onSaveInstanceState(Bundle b) {
super.onSaveInstanceState(b);
b.putString("dbtext", textView.getText());
}
My goal is to create a method that gets the data from broadcast receiver and sends it trough a socket. I know how to send it, but how can i get a data from BroadcastReceiver ? I want to receive data in this class:
public class ClientThread implements Runnable{
Socket socket;
public final String TAG = "CLIENT";
ObjectOutputStream os;
TextView text;
Handler handler;
AppHelper helperClass;
Activity mActivity;
Context mContext;
public ClientThread(Activity mActivity,TextView text,Context context) {
// TODO Auto-generated constructor stub
this.text=text;
this.mContext=context;;
helperClass = new AppHelper(context, mActivity);
handler = new Handler();
}
#Override
public void run() {
// TODO Auto-generated method stub
try {
while (true) {
socket = new Socket("192.168.1.10", 9000);
handler.post(new Runnable() {
#Override
public void run() {
text.setText("Connected.");
try {
os = new ObjectOutputStream(socket
.getOutputStream());
} catch (Exception e) {
text.setText("Output stream. smth wrong");
Log.i(TAG, "Output stream. smth wrong");
}
}
});
try {
ObjectInputStream in = new ObjectInputStream(
socket.getInputStream());
String line = null;
while ((line = in.readUTF().toString()) != null) {
Log.d("ServerActivity", line);
final String mesg = line;
handler.post(new Runnable() {
#Override
public void run() {
if (mesg.contains("getcontacts")) {
try {
sendContacts();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else if (mesg.contains("getmsg")) {
getMessages();
} else if (mesg.contains("sendmsg")) {
sendMessage(mesg);
} else {
// DO WHATEVER YOU WANT TO THE FRONT END
// THIS IS WHERE YOU CAN BE CREATIVE
text.append(mesg + "\n");
}
}
});
}
break;
} catch (Exception e) {
handler.post(new Runnable() {
#Override
public void run() {
text.setText("Oops. Connection interrupted. Please reconnect your phones.");
}
});
e.printStackTrace();
}
}
} catch (Exception x) {
}
}
public void receivedMessage(String sender, String message) {
}
private void sendMessage(String s) {
String[] x = s.split(" ");
int lenght = x.length;
String message = x[2];
for (int i = 3; i < x.length; i++) {
message = message + " " + x[i];
}
System.out.println(message);
SmsManager smsManager = SmsManager.getDefault();
System.out.println("sending message");
smsManager.sendTextMessage(x[1], null, message, null, null);
System.out.println("message send");
}
private void sendContacts() throws IOException {
final List<Person> list = helperClass.getContacts();
final String json = new Gson().toJson(list);
Log.i(TAG, "lenght " + json.length());
handler.post(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
try {
os.writeObject(json);
os.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
Log.e(TAG, "Sending Contact list has failed");
e.printStackTrace();
}
}
});
}
private void getMessages() {
// TODO Auto-generated method stub
ProgressTask task = new ProgressTask();
ProgressTask.execute(new Runnable() {
#Override
public void run() {

os.flush();
System.out.println("List of messages send");
} catch (Exception e) {
Log.e(TAG, "Sending Contact list has failed");
}
}
});
}
}
You may use an interface as listener to this runnable.
Create a Listener interface
Declare Interface Variable in Application Context.
Instantiate and implement interface in Runnable class.
In BroadcastReciever, call method of that interface.
Ex:
Class A extends Application{
public Listener listener;
}`
interface Listener{
public void yourmethod();
}
In Your clientthread method instantiate listener as follows:
((A)context.getApplication()).listener = new Listener(){
#override
public void yourmethod(){
// your implementation goes here
}
}
In your broadcast reciever.
((A)context.getApplication()).listener.yourmethod();

And make layout-land folder for Landscape and put all landscape layout, All Landscape Layout is working fine but when i rotate on Main Activity then It,s close.
removed layout-land folder and tried then again close the App

Please Help Me How can fix this issue
Thanks In Advance
I have a custom list view that is getting data from server and changing its content after each 3 seconds.this list view i am using for showing the visitor list who are visiting the site.Each row of list contains ipaddress,statustext,duration time,noofvisit and button text and data is updating and changing in list this part is working fine.
Actually i have an issue i have to the row on the top as first row of listview if status text is chat request.How can i do this?can anyone help me?
Actually i am using tabhost after login screen tabhost contains for tab one for monitoring window that show list of visitor and other are chat window,operatorlist and controls.
As i define above if i got status chat request then that row should appear on the top and will contains two button Accept and deny and on accept button click a window will open for chat and deny will use for refusing chat.
Can anyone help me for solving this issue?

what can i do for setting the row that has chat request on the top?Can anyone help me?
Create you customListItem with visibility set to View.GONE by default. When you have a chat request, then just change its visibility to View.VISIBLE and refresh your list. Simple.
If you want to add some view as the first row of your listview, then use
listview.addHeaderView(myHeaderView);
use this before setting list adapter.
try like this..
boolean bool=true;
new Thread(new Runnable() {
public void run() {
while(bool){
int t=StatusText.IndexOf(chat)
if(t!=-1)
{
Collections.swap(StatusText,0,t);
Collections.swap(SessionText,0,t);
Collections.swap(IPText,0,t);
Collections.swap(DurationText,0,t);
Collections.swap( NoOfVisit ,0,t);
Collections.swap(ButtonText,0,t);
}
runOnUiThread(new Runnable() {
public void run() {
adapter.notifyDataSetChanged();
}
});
