Question

I want to develop an application that shows an authentication screen one time after installing it, and then other screens on subsequent runs. Is there a way to do it?

Answer 1

Use SharedPreference to store a firstboot value, and check in the activity against that value. If the value is set, then the application has been launched before. Otherwise, you will display the activity and setthe firstrun flag in the SharedPreference.

For example, your your launched activity might look something like this,

public void onCreate(){
    boolean firstboot = getSharedPreference("BOOT_PREF", MODE_PRIVATE).getBoolean("firstboot", true);

    if (firstboot){
        // 1) Launch the authentication activity

        // 2) Then save the state
        getSharedPreference("BOOT_PREF", MODE_PRIVATE)
            .edit()
            .putBoolean("firstboot", false)
            .commit();
    }
}
