converting a java code into an android application

Question

i have got a java code for a oAuth login in the Indivo server. It is working good when I'm running it from the terminal. Now, I would like to convert it to an Android app, doing pretty much the same thing. What are the necessary changes that I need to incorporate, in order to convert this raw java code into a running Android application?

When I copy the same code, and import the necessary packages, it gives an error in the class definition, and in the main declaration. it says "the main method cannot be declared static".

Here is the java code:

Firstly, you need an Android component to launch your class - it can be either Activity, Service or Application.

Secondly, you need to launch a thread with your code, as network calls are not ok to be executed on the UI thread.

Begin with android development here.

about the first part of your answer, in the MainActivity.java file, in my android project, if i create an activity and then copy the same code there, is that going to be any good?? – Ritwik Dey Jan 17 '13 at 07:19
for instance: public class MainActivity extends Activity { Button start; Protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); start = (Button) findViewById(R.id.login); start.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { ------------ ------------ ------------ } } – Ritwik Dey Jan 17 '13 at 07:21
well, what i did was, i wrote the java code in a seperate java file, under the src folder. and then, in the MainActivity.java file, i added this code under OnClickListener: ChromeTest ct = new ChromeTest(); //ChromeTest is the class name String args[] = {""}; ct.main(args); But this, upon compilation, gives "Conversion to Dalvik format failed with error 1" error. – Ritwik Dey Jan 17 '13 at 09:28
You should refer to AsyncTask class, see this question http://stackoverflow.com/questions/4538338/progressdialog-in-asynctask/4538370#4538370 – Vladimir Ivanov Jan 17 '13 at 09:54
Hey Vladimir, went through the thread that u said. To be very frank, couldn't figure out most of the code.. I am still an amateur in Android and java. Could you please help me out by actually drafting the required code segments, if i provide you with the java code and the .jar files, if required? Maybe that will help me understand things better. Thanks a lot... – Ritwik Dey Jan 17 '13 at 11:48
mention some public contact information in your details, I will write you a message. – Vladimir Ivanov Jan 17 '13 at 13:07
my email id is already mentioned in my profile. you can drop me a mail there. Thank you. – Ritwik Dey Jan 17 '13 at 13:26

You should create library project for your java code then use into a Android application and read http://developer.android.com/ to work with Android.

I had all the necessary jar files, and i have added them in the referenced library, using build path. Is that what you tried to say? – Ritwik Dey Jan 17 '13 at 07:25
Android code didn't have the main method because as per architecture Android application has not a single entry point, each Activity can work as entry point. You should create Activity as per Android architecture then use your java code. – Ashish Jan 17 '13 at 07:50
I once heard a saying by Einstein, which goes like "If you can't explain it simply, you don't understand it well enough." Instead of quoting things from the android developer site, can u give me a straight solution to the problem, if u have any? And i'm not stupid to look for a main method in the android code. main method existed in java code, as it should. I just wanted to know of a way by which i can get this running in Android.. – Ritwik Dey Jan 17 '13 at 09:40
Well you just want a ready-made solution of your problem didn't want to put any effort Best of Luck!! – Ashish Jan 17 '13 at 10:26
