what wrong with putExtra and string values

Ok....what's wrong with this? Ive made a button...added this to the intent:

intent.putExtra("test","test");

then in onReceive had a little problem:

Bundle extras = intent.getExtras();
Log.v("Test", "Ok lets see");
String t=extras.getString("test");
Log.v("Test", "t="+t);
if(t=="test") t="tada";
else t="test";
Log.v("Test", "Ok...t="+t);

Now see the results from log

07-02 23:48:24.195    6278-6278/com.example.widget             V/Test: Ok lets see
07-02 23:48:24.205    6278-6278/com.example.widget             V/Test: t=test
07-02 23:48:24.205    6278-6278/com.example.widget             V/Test: Ok...t=test

Took me 1-2 hours to find out what was wrong with my code. Of course i have no idea what is wrong with the example above. My solution was to change from string to numbers (byte in my case). So after that everything was ok.

You're comparing Strings using ==, which only works if they refer to the exact same object.

Use the equals method instead.

if(t.equals("test"))
    t = "tada";

Log.v(t) //Logs tada
