How to read adb response from jar?

Question

I am trying to batch some apps installations and I want to do it app by app. I am trying to get the adb command response into my java program but I don't manage to understand why I don't get anything from an InputStream !

Here is my test code:

import java.io.IOException;
import java.io.InputStream;

public class main_adbStreamTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {

            Process pro = Runtime.getRuntime().exec("platform-tools\\adb.exe -s " + args[0] + ":5555 install -r " + args[1]);   // + " >> " + SBCWLogger.getFileHandlerName()

            //add installation verification
            InputStream is = pro.getInputStream();
            int i = 0;
            while( (i = is.read() ) != -1) {
                System.out.print((char)i);
            }
            //verification done
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

I found this answer which is not working, and I do not manage to use pro.getInputStream() properly either.

I also tried most of the answers from here but none of those I tested worked. I successfully read the errors when I don't connect or when the install fails, but not the informational messages as Success at the end of an install. And that is what I want.

EDIT : the code below is working thanks to Onix' answer.

import java.io.IOException;
import java.io.InputStream;

public class main_adbStreamTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {

            Process pro = new ProcessBuilder("platform-tools\\adb.exe", "-s",args[0], "install", "-r", args[1]).start();

            //add installation verification
            InputStream is = pro.getInputStream();
            int i = 0;
            while( (i = is.read() ) != -1) {
                System.out.print((char)i);
            }
            //verification done
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

And to get the famous Success , just write the stream to a file and read the last row.

Answer 1

Try this

Process process = new ProcessBuilder("Full path to adb", "-s", args[0], "install", "-r", args[1]).start();    
InputStream is = process.getInputStream();
