I am trying to implement OAuth Stack Exchange API via Android app as client. After a successful login from out I get the below URL how do I get or decode the access_token from the hash?

https://stackoverflow.com/oauth/authorize?client_id=14702 &accountId=15559293 &scope=no_expiry &returnUrl=https%3a%2f%2fstackoverflow.com%2foauth%2fdialog%3fclient_id%3d14702%26scope%3dno_expiry%26redirect_uri%3dhttps%3a%2f%2fstackexchange.com%2foauth%2flogin_success&nonce=HDE6GdCUbq90z7Uq6l8FHg))&ticks=636889445649720585&flowKind=Implicit&hash=6d3bbaad65ce8277bc8f357d8b594d63252ba270ee0fe163b11d1cac6e5583c6

Refer to the API Authentication docs; there are a great many things wrong with the URL in the question (at least 5).

For starters, it's to the wrong path. stackoverflow.com/oauth/authorize gives helpful messages/results like:

  • Oops! Something Bad Happened!

  • Authorization attempt not valid for current user

  • Authorization attempt unauthorized

  • Couldn't parse ticks (etc)

None of these messages hint at the real problems.

Anyway the correct URL per the (incorrect) docs is https://stackoverflow.com/oauth/dialog.

But it's more correct to use: https://stackexchange.com/oauth/dialog.

All the extra and redundant parameters you were passing are normally ignored (or sometimes throw an error).

The correct way to get an access token is like:
    https://stackexchange.com/oauth/dialog?client_id=14702&scope=no_expiry&redirect_uri=https://stackexchange.com/oauth/login_success
(Click it and see)

If you want to pass additional security values, they must be the state parameter.
For example, calling:

https://stackexchange.com/oauth/dialog?client_id=14702&scope=no_expiry&redirect_uri=https://stackexchange.com/oauth/login_success&state=nonce=HDE6GdCU,ticks=636889445649720585

Note the comma-separated values.

The above call yields:

https://stackexchange.com/oauth/login_success#access_token=nUh_no_peaking_f8xkByw))&state=nonce%3dHDE6GdCU%2cticks%3d636889445649720585

Where state decodeURIComponent decodes to: state=nonce=HDE6GdCU,ticks=636889445649720585 (the value passed in).
