How to pass string and int from one activity to another in Android across different projects in Eclipse?

Question

I am trying to send a set of data from one Activity under project A , package a , into another Activity under project B , package b for Android project integration.

How to modify the Intent myintent = new Intent () in order can such be achieved?

The below is my part of code of project A, package a ..

try {
    Intent myIntent = new Intent();
    Bundle myData = new Bundle();
    myData.putInt("cntKey", contractKey);
    myData.putInt("workTypeKey", workType);
    myData.putInt("estateIDKey", estateID);
    myData.putInt("workIDKey", workID);
    myData.putInt("blockIDKey", blockID);
    myData.putInt("districtIDKey", districtID);
    myData.putString("estateRoomNumKey", estateRoomNumber);
    myData.putString("estateKey", estate);
    myData.putString("blockKey", block);
    myIntent.putExtras(myData);
    startActivityForResult(myIntent,0);
} catch (Exception e) {
    Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}

Now I am trying to pass some data from one Activity , package a , project A into another Activity, package b , Project B

The Project A itself is a library project.

What should I begin with if using Indents and Bundle?

do you want to pass data between two activities present in different packages or between two activities present in different sub packages but under a common package?? — Parth Doshi, Jul 06 '12 at 04:48

I think what you need to use is a broadcast.

what about if the values of these variables are only used within these Activities ? 3 – Jeff Bootsholz Jul 06 '12 at 07:30

If you can modify project B also, I would just go with

myIntent = new Intent("some.very.unique.id.that.you.define")

and then declare an intent filter for that id in the Android manifest of activity B in package B.

Other activities of third party party apps could also register the same intent filter, so don't use this solution if you want to transfer sensitive data. In such a case, the full solution would probably be AIDL.
