snippet accesso root

[Azatoth]

                TextView tv = (TextView) findViewById(R.id.test);
        
		Process p;
		try {
			p = Runtime.getRuntime().exec("su");
			DataOutputStream os = new DataOutputStream(p.getOutputStream());
			os.writeBytes("echo \"CIAO MAMMA!!!!!!!!\" >/system/sd/ciccio.txt\n");
			os.writeBytes("exit\n");
			os.flush();
			try {
				p.waitFor();
			        if (p.exitValue() != 255) {
				        tv.setText("OK!");
			        }
			        else {
				        tv.setText("Errore nella richiesta permessi di Root");	
			        }
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

Ovviamente c'è da implementare le eccezioni e la logica di business
