Question

When my application starts, login Activity appears. It contains checkbox “sign me next time”. I want to start another Activity next time of application starting and send username and password of user to it if checkbox was checked.

How can I implement this?

Answer 1

You probably want to save the username and checkbox value in the SharedPreferences.
After that you can retrieve them when the application starts.

Example:

//Saving the values
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("username",username);
editor.putString("password",password);
editor.putBoolean("isChecked", isCheckBoxChecked);
editor.commit();

//Retrieving the values
SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
if(sharedPreferences.getBoolean("isChecked"))
{
     //Do whatever you need to do if it's checked
}
