transferring boolean value between two avtivities

Question

i am developing an android application which call my Starting activity from another activity. since i am calling my 1st activity i cannot use intent to transfer a Boolean variable so i created a object of my calling activity and accessed data though it. like this

Activity1 log=new Activity1();
boolean stat=log.aResponse;

i checked the value of aResponse in my Activity1 its value is true. but in my starting activity the value of stat is false all the time. I tried the same code in another activity(which is not my 1st activity) in that also the value i obtain is false. anybody please help me.

You should google this first..!! see this : http://stackoverflow.com/q/2091465/6127411. — Janki Gadhiya, Jun 06 '16 at 12:09
i cant use intent because the Activity1 is calling the 1st activity of my application. if i use an intent then i cant launch the app. — NITHIN SUHAS, Jun 06 '16 at 12:13
you should use bundle for passing arguments through intent please explain why can't you use intent. — Mithilesh Izardar, Jun 06 '16 at 12:14
you can still use an intent even if you want to launch your first activity.. — Vikram Singh, Jun 06 '16 at 12:17
Activity1 is calling the launching activity of the app. thats why i cant use intent. — NITHIN SUHAS, Jun 06 '16 at 12:19
Yeah, nobody really knows what you mean by that, or why it's preventing you from passing data with an `Intent`. You need to provide more detail. — Mike M., Jun 06 '16 at 12:20
my app launches **startingactivity**, user can login in activity1. after the login the value **aResponse** is set to true. then **activity1** calls the starting activity. from on that the value of stat determines different propertie. — NITHIN SUHAS, Jun 06 '16 at 12:24

you can simply call your launching activity by this:

Intent i = new Intent(Activity1.this, StartingActivity.class);
i.putExtra("varName", variable);//values you want to carry
startActivity(i);

if your app is crashing using this code, please post crash logs for the possible reason.. – Vikram Singh Jun 06 '16 at 12:28
but that code will make my app crash. because at first run StartingActivity does not have any intent to receive (as its the first activity launched) – NITHIN SUHAS Jun 06 '16 at 12:28
no, it is nothing like this. It will receive intent as well as the values you are passing in bundle..the reason of crash is something else.. – Vikram Singh Jun 06 '16 at 12:31
that cleared the problem thanks. – NITHIN SUHAS Jun 06 '16 at 12:44

This is a bad way to this. You should go back to basics. Workflow should go like this:

Intent i = new Intent(this, YourNextActivity.class);
i.putExtra("varName", variable);
startActivity(i);

Then to get the value in YourNextActivity:

boolean defaultValue = false;
boolean varName = getIntent().getBooleanExtra("varName",defaultValue)
