Android Getting Results from another activity

I have a problem with my code. I want to pass a String from the SecondActivity to FirstActvity. Note that the FirstActivity is not visible but its still open. when the SecondActivity is finish it passes a String to the FirstActivity.

My problem here is that when the SecondActivity ended and goes to FirstActivity, the whole application closes.

FirstActivity to SecondActivity:

Intent  intent = new Intent(MainActivity.this, FileChooser.class);
startActivityForResult(intent, 0);

SecondActivity to FirstActivity:

Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("filePath", "/sdcard/path1");
setResult(0);
finish();

FirstActivity Result:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    //TODO handle here.         
    Intent intent = getIntent();        
    this.filePath = intent.getExtras().getString("filePath");
}

What is wrong with the code?

When you set the result of your SecondActivity, you only set the result code. Instead of setResult(0) use setResult(0,intent)

Also, in your FirstActivity's onActivityResult get the extra from the data argument - this.filePath = data.getExtras().getString("filePath");

Try to use 

data.getExtras().getString("filePath");

instead of 

intent.getExtras().getString("filePath");`

Try with Bundle:

First Activity; 

public void onClick(View v) {
        Intent intent = new Intent(v.getContext(), FIRSTACTIVITY.class);
        Bundle bundle = new Bundle();
        bundle.putString("filePath","/sdcard/path1");
        intent.putExtras(bundle);               
        startActivity(intent);
    }

Second Activity: 

public void activity_value() {
    Intent i = getIntent();
    Bundle extras=i.getExtras();
    if(extras !=null) {           
        value = extras.getString("filePath");
    }
}
