OpenTok Multiple user video calling in android with changing video screen size when touched as on whatsapp

I am using opentok videocall library in android. I want the same feature as in WhatsApp. in this app, there are 3 subscribers and 1 publisher view on my screen. when we touch any subscriber view it should switch with a full-screen view. I am attaching a screen for better understanding.
in this screen when we touch subscriber 2 view, it should exchange its view with subscriber 1 and when we press any other subscriber view it should exchange with the main view which is in large size.
screen two
screen three
My code is here, in this I am able to switch subscriber with each other but not able to manage them in main screen.

Opentok will not do that for you, because that's your functionality. You need to capture screen presses, and resize the canvas for publishers/subscribers by yourself. We don't handle how you want to show subscribers in your screen.

Android to Arduino Leonardo communication - sending and receiving commands over an OTG Cable

I am trying to build an Android Application and I have an Arduino Leonardo board that sends output via the keyboard write command. So far, I am able to receive the Arduino output on my Android device as keyboard input. I have an EditText text that just receives all the Arduino output and when the output sequence is over, I can then parse the EditText value easily.
However, the issue I'm having right now is sending data from Android to Arduino. I've done my research and the recommended/common ways of communication between Android and Arduino is via Bluetooth where the Android will send data to an Arduino with a Bluetooth shield. This is a viable solution, however, we have limited resources. I've also seen stackoverflow questions that involved an OTG Cable but those were communicating to Arduino Uno. It seems that those solutions did not work on Leonardo. I've also seen blogs wherein people in the comments section would ask on how to implement a cable based communication system between Android and Arduino Leonardo.
How can I resolve this problem? It seems like the communication interface/protocol across Arduino boards are different.
Also, as a side note, is it possible to use a different command to send data from Arduino Leonardo to Android aside from the keyboard write command?

This example show how to send String from Android to Arduino Uni via USB OTG cable, before sending you must be know about the
vendor-id="9025"
product-id="0067"
of Arduino have a look for this example

Android service restarts, but application does not

I am developing an application that sends over a webservice information about the last dialed number, call status, and duration of the call.
The application works perfectly fine, but when the device closes the application the android service does restart but the activity does not.
The way I am sure about that is that I have Toasts when the service is started: "Servicio TRUCKA iniciado" and "Servicio TRUCKA creado" tell me that the service has been created and started.
And when the information is sent to the webservice I have toasts saying: "Enviando información..." and "Información enviada."
But when the application is closed (via the android task manager that automatically closes apps) the messages from the service "Servicio TRUCKA iniciado" and "Servicio TRUCKA creado" do appear, but the toasts from the information sent part do not.
I hope someone can help me and tell what am I doing wrong? :)

Android Layout help needed

I am having difficulty making my layout to work...
What I want to do is have two spinners and a button below those and once the button is clicked, I display the results based on the values selected in the spinners.
-----------
| Spinner 1 |
-----------
-----------
| Spinner 2 |
-----------
-----------
| Button |
-----------
Result 1
Result 2
Result 3
Result 4
Result 5
I have tried to put the results in a ListView, but the problem I face is that once the button is clicked, I can see the repetition of Spinner1, Spinner2 and the Button itself multiple times.
The xml for the layout is as follows:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="#array/country_arrays"
android:prompt="#string/country_prompt" />
<Spinner
android:id="#+id/spinner2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:entries="#array/country_arrays"
android:prompt="#string/country_prompt" />
<Button
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/done" />
<LinearLayout
android:id="#+id/moreContent"
android:layout_width="match_parent"
android:visibility="visible"
android:orientation="vertical"
android:layout_height="wrap_content"
>
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:textColor="#ff0000"
android:textSize="12sp" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:contentDescription="#string/hello_world"
android:gravity="center_vertical"
android:text="#string/hello_world"
android:textColor="#0000ff"
android:textSize="12sp" />
</LinearLayout>

The adapter is as follows:

import android.view.ViewGroup;

import android.widget.TextView;
public class TimetableAdapter extends ArrayAdapter<TimeTable>{
private final Context context;
private final ArrayList<TimeTable> values;
public TimetableAdapter(Context context, ArrayList<TimeTable> values){
super(context, R.layout.activity_main, values);
this.context = context;
this.values = values;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.activity_main, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.textView1);
TextView textView2 = (TextView) rowView.findViewById(R.id.textView2);
//System.err.println("Position is : "+position);
TimeTable tt = values.get(position);
textView.setText(tt.get_departure());
textView2.setText(tt.get_arrival());
return rowView;
}
}

The problem is due to
View rowView = inflater.inflate(R.layout.activity_main, parent, false);
in getView() method.
You are inflating whole activity_main in a row and then adding it to a listview.
Put a row for results in separate xml instead of activity_main. So you will have a new xml file say, row.xml which will contain:
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:textColor="#ff0000"
android:textSize="12sp" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:contentDescription="#string/hello_world"
android:gravity="center_vertical"
android:text="#string/hello_world"
android:textColor="#0000ff"
android:textSize="12sp" />
So you will have to inflate as
View rowView = inflater.inflate(R.layout.row, parent, false);
And then add the generated rows in the listview which is in activity_main.xml.
So your problem will be solved. Hope it helps.

Write or append string to a file. Getting read only file system error

First off I wanted to thank everyone for the help I've gotten on my last few questions. I've searched and done my best to figure out my latest problem but I've had no luck even after searching here. I'm trying to check to see if "heapFile.csv" exists and if it doesn't, to create the file and then write a string to it. If it does then I just want to append a string to it instead. I think what I have will do that but I keep getting an IOException along with it saying the file system is Read Only. I do have the manifest file changed to include accessing the sdcard and even used the android too to make a virtual sdcard in case that was the problem.

I think problem is in this line:
FileWriter heapFileWritter = new FileWriter(
heapFile.getName(), true);
instead try this:
FileWriter heapFileWritter = new FileWriter(
heapFile, true);
explanation:
heapFile.getName() refers to your file name so lets say heapFile.txt.
so when you ask FileWriter to write to this file. It doesn't know which file you are referring to. So it try to create the file. But wait! where it will create the file, as it has only the file name, not the complete path.
So even I am sure where it would think of creating the file, my guess is Root( I am not sure). Which is read-only hence the error.
public FileWriter(String fileName,
boolean append)
throws IOException
IOException - if the named file exists but is a directory rather than
a regular file, does not exist but cannot be created, or cannot be
opened for any other reason
