    I have the following problem: I’m doing some tests on applications with robotium and i want to restart the application from within the test case. Below is the code I’m working on

    public testtest(){


    public void setUp() throws Exception {
    solo = new Solo(getInstrumentation(), getActivity());

    public void testFai() throws Exception {

    Where can I go to write something in order to restart the application? Thank you very much

    It is for restarting first activity of the application from any other activity.

    For example, the android application name is “MyApp” and with an activity for login “LoginActivity”. When the application starts it lunches LoginActivity, after successful loggedin it may open new other activities such as DisplayInfoActivity1, DisplayInfoActivity2 and so on. Then if it is needed that you want to restart from first LoginActivity wherever it is now, you can call this method which reside in that activity from where it’s necessary to restart, for example, in DisplayInfoActivity2.
