Setting start and end duration of song with range seekbar

I'm trying to incorporate somehow into Android audio player, functionality of marking of the fragment of the song in the player that it is supposed to play. I see this like clipping of the fragment as in Audacity. I'm trying to get it with a range seekbar (two blue dots on a line that can be adjust) on which user mark the beginning and the end to play and when replay mode is enabled the player will play that marked section over and over again.
It looks like on this image
The application is written in the Java language.
Below are the related code.

Variable string in setCommand function of JSch Android

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!
My Program is a bit long but You can find a simple program of JSch implementation Here (The second answer).
If you still want to look at my code (things are in copyMethod() and executeRemoteCommand() function):

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...

How to put a progress bar with thread safety in android while hitting a server and waiting for response?

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

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.
<?xml version="1.0" encoding="utf-8"?>

Onclicklistener only working once

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.

Android app activity button timeout selection

I have a basic android app using the zxing scanner and an activity with 3 buttons. The scanner sends a code to the activity, and the user can choose to clock in, clock out, or cancel the operation. This works fine. I want to add an auto timeout to this process, so that if the user does not click a button in a specific time period, the system will determine if they are in or out (cancel button must be pressed). I have the logic for all of this, but I don't know how to add the timeout logic. There is the initial layout, the activity Java code, the SQLite database object and handler, the zxing integration, and an ASync post. I have included the main java class below, which includes the onClick event and primary integration between zxing and the SQLite (those are omitted).
Any thoughts on how I could implement a basic timeout? I would like a function to be called from the main java class if a button is not pressed, and this function will determine (based on the last selection) if they are in or out.
Thanks for any help or suggestions you can provide.
