Question

How to pass data between two activities in android?

Following is my code:-

Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent)

Second I used SharedPreferences for that:-

For Pass Data:-

 SharedPreferences gameSettings = getSharedPreferences("MyGamePreferences",MODE_PRIVATE);  
 SharedPreferences.Editor prefEditor = gameSettings.edit();  
 prefEditor.putString("UserName", "Guest123");  
 prefEditor.putBoolean("PaidUser", false);  
 prefEditor.commit();

For Getting Data in next Activity:-

SharedPreferences gameSettings = PreferenceManager
                                .getDefaultSharedPreferences(getBaseContext());
String s= gameSettings.getString("UserName", "Dipak");
Boolean b= gameSettings.getBoolean("PaidUser", true);

but data is not getting in next activity.

Answer 1

Why don’t you use mIntent.putExtra() for passing data to another activity?

Seeing your coding,you can get your sessionId in next activity using:(assuming your sessionId as integer)

int sessionId=getIntent().getIntExtra("EXTRA_SESSION_ID");

And the way you are getting values from SharedPreferences is absolutely correct.I don’t know why you are not getting them in next activity.
