I have a question regarding Android socket client application. I am suppose to use it to test the connection with a socket server software. But the application crashes everytime i press any of the button once. Does anyone know where the problem lies in my application?

Check your stack trace. The exception is thrown by
commsThread.write(data[0]);
That clearly indicates that either commsThread or data is null.

and also compile error is . I hope your immidiate answer
About file save, In Android (6.0+), I must be write files in /data directory, only with permission do write (without manifest permissions)
Example:
String directory = "/Android/data/" + getPackageName();
String pathToSave = directory + "/" + FILE_NAME;
About error, I need more details
I want to execute the following command through ssh on my raspberry pi from Android App:
echo 'value of a variable string named cmd' > filename.txt
I tried following:
String a="echo '";
String c="' > filename.txt";
String cmd=a+clip+b;
channelSsh.setCommand(cmd);
Normal commands like "sudo reboot" works but not this!

the clip inside the executeRemoteCommand() method in always null where you used String cmd=a+clip+c;
And you are calling ClipData.toString() here which returns string representation of the object
to get the text from ClipData use
String text = "";
ClipData clip = getPrimaryClip();
if (clip != null && clip.getItemCount() > 0) {
text = clip.getItemAt(0).coerceToText(mContext);
}
it will retrieves the primary clip and coerce it to a string
use Log to log the command before executing and check if you are using the correct command
I solved my problem,... thankyou for your time... thnx Arpan...

I have an application where I am recording audio in an activity. User has a start recording and stop recording button to do that. Once user clicks the stop recording button, it sends the recorded mp3 file to server (encoded string) and server process it and a response is received. I want to do the following tasks:
Since this process is long, I want to do this in a separate thread(preferably).
The process of sending and receiving response is to be shown using progress bar.
User should be able to navigate to other screens while he is waiting(i.e. current activity may be destroyed)
I tried using Toast messages before and after the function where I send mp3 to server. But there is no sync, sometimes msg comes early, sometime it's late. That's why a proper progress bar is required.How to do this? Can AsyncTask be used with what I want to achieve in (3). or should I use some other form of multithreading. Please help.Below is the activity
(Please ignore the indentations, I couldn't fix the code on stack-overflow:

You can use an IntentService to upload your content to the server. By default, it runs on a seperate thread and is not activity bound. Then use a broadcast receiver to communicate the result back to any activity. You can find an example here.
For the progress bar, you can create a notification and show the progress bar there, this will not block your application's UI.
For hitting the server at you should use AsyncTask or Runnable thread, without disturb the main tread
for custome progress dialog use the following code
xml file.

My onclicklistener for my "LoginBtn". However that code inside that block only runs once and then doesn't run ever again. Please help me, I've tried everything. I know so because I have ran the log and it only logs out the value once and then never again.

I want to customize the text inside the edittext of my chatting app. I want to bold the username and normal font for his message.
For example;
usernamejay: Hi This is Jay. How are you?
also make 1 space for reply after the message of usernamejay. i also want to change font color of username. Also if possible put message balloon for every message.
Example:
usernamejay: Hi This is Jay. How are you?
usernameclark: I'm Fine. Can i call you now for a meeting?
Can anyone help me how. This is the code for Java

Do this way Hope this works for you
EditText editText = (EditText)findViewById(R.id.editText);
String userName = "usernamejay";
String message = "Hi This is Jay. How are you?";
String finalStr = "<b>"+userName+":</b> "+message+"";
editText.setText(Html.fromHtml(finalStr));
On Android you can use HTML to style the text inside a TextView, see here http://daniel-codes.blogspot.pt/2011/04/html-in-textviews.html
You could also use a spannable string, may be you could look at a portion of the code in this answer.
A code extract from the link
final SpannableString out0 = new SpannableString(source[position]);
StyleSpan boldSpan = new StyleSpan(Typeface.BOLD);
out0.setSpan(boldSpan, 6, 17, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
holder.tv.setText(out0);
P.S: but please read the solution in the link before you start applying things in your code.
