  • Android- Error during executing Runtime.getRuntime().exec() - Environment Null -ffmpeg

    18 février 2015, par Chaitanya Chandurkar

    I have compiled ffmpeg library on ubuntu 11.10 and ported compiled files on android.
    After compiling i got libffmpeg.so successfully. It gets loaded on android successfully.

    I am doing it on ubuntu 11.10 eclipse android emulator.

    I have created a small test application which act as command prompt which accepts command from user and displays result. (testing ffmpeg commands)

    When i run simple commands like "ls", "ls -l" it works perfectly. but when i simply type "cd mnt" or "ffmpeg" as command and try to run it. I got Warnings in Logcat saying that

    Here is my code :

        BufferedReader stdInput = new BufferedReader(new 
    
                InputStreamReader(process.getInputStream()));
    

    
           BufferedReader stdError = new BufferedReader(new

           TextView output=(TextView)findViewById(R.id.output);
    
           TextView error=(TextView)findViewById(R.id.error);
    

    
            while ((s = stdInput.readLine()) != null) {
    
                   text+=s.toString()+"\n";
    
                   System.out.println("Error: "+s);
    
               }
    

    
         output.setText(text);
    
         text="";
    
           // read any errors from the attempted command
    
           System.out.println("Here is the standard error of the command (if any):\n");
    
           while ((s = stdError.readLine()) != null) {
    
               text+=s.toString()+"\n";
    
               System.out.println("Error: "+s);
    
           }
    

    
           error.setText(text);
    

    
           error.setMovementMethod(new ScrollingMovementMethod());
    
           output.setMovementMethod(new ScrollingMovementMethod());
    

    
           stdInput.close();
    
           stdError.close();
    

    
           process.waitFor();
    
           process.getOutputStream().close();
    
           process.getInputStream().close();
    
           process.getErrorStream().close(); 
    
           process.destroy();
    

    

    
    }
    

    
}

    I even tried process = pb.command(com).redirectErrorStream(true).start(); for execution. It gives me same error but this time environment was [ANDROID_SOCKET_Zygot] bla bla bla..

    EDIT 1 :
    I use Openjdk on ubuntu

    Help me out !!
