I cannot pass and retrieve intent boolean extra

Question

I am trying to make my code pass boolean extra via intent but I fail.I debugged and observed that my activity "B" assigns the value of EXTRA_IS_ADDED as true, as I wanted to but than when I call startActivity(intent),in my activity "A" I cannot use this data correctly to assign isAddeds value.

Here is the activity A as I call :

package com.example.recepinanc.whenfreedeneme;

Answer 1

I've moved my original comment to an answer so you can mark the question as solved. ;)

private Boolean isAdded; is Boolean (object) and not boolean (primitive type), so some automatic boxing and unboxing may be happening here. I cannot spot anything else, but it may be worth trying to change it to private boolean isAdded;

Answer 2

Notice that getBoolean is returning boolean (Primitive type) and not Boolean.

From the docs:

public boolean getBooleanExtra (String name, boolean defaultValue)

Added in API level 1 Retrieve extended data from the intent.

Parameters name The name of the desired item. defaultValue the value to be returned if no value of the desired type is stored with the given name. Returns the value of an item that previously added with putExtra() or the default value if none was found. See Also putExtra(String, boolean)

Change

private Boolean isAdded;

to

private boolean isAdded;
