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

Question

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.

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.

u Didn't get my point. I am able to start another intent but the problem is that the string i am passing with the key value "check" or "check1" is received by the Connection Activity class with the value client or server. Not both. To be more precise i am opening same application on two phones On one side i click server and on the other i click client but it only receives one value "server" or "client" from the putExtra() method – Shashank Sood May 22 '13 at 12:38

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.

my friend have you got the answer or your problem is still there ?? — Syed_Adeel, May 27 '13 at 13:29
