Question

I would like to integrate an application (lets call this app1), into another application (app2), which will invoke app1 with a button click. What are the possible ways of achieving this, without exposing the source code of app1 to app2. app1 shouldn’t be installed as a saperate application, it should be part of app1.

I was thinking to somehow convert app1 to a jar file and integrate it in to app2, is this possible?, or suggest me some ways to achieve the above requirement.

Answer 1

If app 1 has android resource files (layouts,xml drawables etc.) and jar dependencies you cannot avoid exposing them.

If you are willing to expose your resource and external jars you can:

1. Change app1 to an android library.
2. Create another library project with the same resources and jars of app1 (without the sources).
3. Copy the generated jar file out of the app1 library project bin folder to the seconds library project libs folder.

The end result is a library project without the java source files but with the resources, this library project can be used in app B without exposing your java files.

Notice that some re-factoring to app1 might be required.
