This is a small sample app to demonstrate how you could integrate SoundCloud in your own Android application. The official SoundCloud app for Android app needs to be installed, if it is missing the user will be asked to install it.

The demo app lets the user pick a piece of audio (using Android intents) which then gets uploaded to SoundCloud (as a private track).

The integration uses the Android account manager to obtain a token and then makes requests using the standard SoundCloud Java API wrapper.

Here a very simplified usage pattern:

AccountManager accountManager = AccountManager.get(this);
Account[] acc = accountManager.getAccountsByType("com.soundcloud.android.account");
if (acc.length > 0) {
    // possibly ask user for permission to obtain token
    String access = accountManager.blockingGetAuthToken(acc[0], "access_token", true);
    Token token = new Token(access, null, Token.SCOPE_NON_EXPIRING);
    ApiWrapper wrapper = new ApiWrapper(null, null, null, token, Env.LIVE);

    HttpResponse resp = wrapper.get(Request.to("/me"));
    // do something with resp
} else {
    // logic to add an account
}

See the sample app for the detailed usage.

The big advantage of this approach is that you have full control over how you use the API, however the drawback of is that your app requires a few more permissions (android.permission.{GET_ACCOUNTS, MANAGE_ACCOUNTS, USE_CREDENTIALS}).

If you just want to upload a file to SoundCloud consider the Android intent sharing method instead.

Once you have obtained a token from the account manager you should probably persist it in your app and only request a new token if necessary.
