Try this: Send an intent (via startActivity() as usual) to bring the activity to the front which contains the tabs. Send an extra parameter with the activity containing the TAG or some identifier for tab, you want to be opened. Evaluate the extra parameter in the activity, which contains the tab and let it switch to the tab as indicated by the parameter.

EDIT

To start the tab activity with a parameter:

final Intent i = new Intent(this, YourTabActivity.class);
i.putExtra(TAB_TAG, tag);  // TAB_ID see comment below, define some tags for the tabs
this.startActivity(i);

To extract the parameter from the intent:

Overwrite onNewIntent() in the tab activity and introduce a field lastIntent, set this.lastIntent = this.getIntent() there. (Otherwise you will always access the intent which started the activity in the first place, not the most recently sent intent!)

in onResume process the last intent:

final Bundle extras = this.lastIntent.getExtras();
final String tabTag = extras.getString(TAB_TAG);    // define the key TAB_TAG as static string

Now use tabTag to set the current tab.
