TextView tv = (TextView)findViewById(R.id.TextView01);
tv.setText("Hello, Android\n
Hello,

findViewById can only be used if you have set a layout for your

Hi Mariano, thanks for your time.
Example :
/ CODE APPLICATION
*System.out.println("Hello");
foo1(); // Simple function
System.out.println("World");
foo2(); // Simple function
System.out.println("Today");
System.out.println("Yesterday");*
