How set runtime (echo) command on boot adoption?

Could anybody help me how can I set this echo command which you can see below on boot adoption (because when I only execute it with button so after restart there are default values again)? I know how make it with BroadcastReceiver, but I have more buttons and each button contains one echo command and I need only last clicked button with echo command set on boot adoption.

Here is example:

public class MyActivity e开发者_JAVA百科xtends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_layout);

        Button b=(Button)findViewById(R.id.btn_button);
        b.setOnClickListener(new OnClickListener(){
            public void onClick(View paramView){

            Process b;
        try {
            b = Runtime.getRuntime().exec("su"); 

            DataOutputStream os = new DataOutputStream(b.getOutputStream()); 
            os.writeBytes("echo '1,1,1,1,1,1' > /sys/module/lowmemorykiller/parameters/minfree\n");
            os.writeBytes("exit\n"); 
            os.flush();
            try {
                b.waitFor();
                if (b.exitValue() != 255) {
                    // TODO Code to run on success
                    toastMessage("root");
                    }
                else {
                    // TODO Code to run on unsuccessful             
                   toastMessage("not root");
                   }
            } catch (InterruptedException e) {
                // TODO Code to run in interrupted exception    
                toastMessage("not root");
                }
        } catch (IOException e) {
            // TODO Code to run in input/output exception
            toastMessage("not root");
            }
            }
        });
    }

THANK YOU.

The question is slightly unclear but from what I can comprehend broadcast is the designed method. This would require that you launch your activity from the service receiving the BOOT_COMPLETE broadcast.

You can launch an activity from your service like this:

Intent intent = new Intent(MyService.this,MyActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

You could either bind the activity to your service or move your "echo" code into a static helper to keep it tidy.

Alternatively if you wish to run your activity as a launcher you can use

<category android:name="android.intent.category.LAUNCHER" />

but that may not be your inteded solution.
