Using intent's putExtra to send data using same Key Value

i want to open an Activity using Intents By following this code:

Intent i=new Intent("com.example.learn.CONNECTION");
@Override
protected void onCreate(Bundle savedInstanceState) {
            .
            .
            .
    server=(Button) findViewById(R.id.Server);
    client=(Button) findViewById(R.id.Client);
    server.setOnClickListener(new OnClickListener(){

        public void onClick(View v) {

                i.putExtra("check", "server");
                startActivity(i);

            // TODO Auto-generated method stub
        }
    });

client.setOnClickListener(new OnClickListener(){

    public void onClick(View v) {
          i.putExtra("check1","client");        
      startActivity(i);

}

}); Now In this Connection Activity I am checking it with:

if(getIntent().hasExtra("check"))
        value = getIntent().getExtras().getString("check");
    if(getIntent().hasExtra("check1"))
        value = getIntent().getExtras().getString("check1");

But the code is not working it either receives client or server. How should i solve this problem is there any other way out. Any other suggestions not related to this code will also be accepted.

dont use different vars like "check" or "check 1" use a flag . this code will save your problem

server.setOnClickListener(new OnClickListener(){

  public void onClick(View v) {

            i.putExtra("check", "server");
            startActivity(i);

        // TODO Auto-generated method stub
    }
});

client.setOnClickListener(new OnClickListener(){

public void onClick(View v) {
      i.putExtra("check","client");        
      startActivity(i);

}

in your next activity, just use this code .

value = getIntent().getStringExtra("check");
if(value.equals("server")){
//server code
}
else if(value.equals("client")){
//client code
}

You can also use some boolean flags in the same way if your server and client values are dynamic.

Dear you are doing a mistake. the sample you provided is used to launch web urls normally. if you want to start another intent then you will have to change the first line only.

Intent intent = new Intent(CurrentActivity.this , NextActivity.class);

Try this please.
