[quote]Great work on your app! I have downloaded the Android version and was able to login and use both modes successfully, no problems. I have shared this post with my friend who was exploring the idea of a similar application. He's an iPhone user so maybe he'll reach out to you for a Test Flight invite.[/quote] Thanks! [quote]I would really love to see how you implemented the OAuth login in the Android app. I noticed as soon as I open the app I'm redirected to the browser to login, etc. which makes sense but I'm unsure how to achieve this flow (and handle the callback) from my Android app. Would you be willing to explain a bit further? I understand you might not want to share your code, but maybe pseudo code? Any help would be appreciated![/quote] Sure no problem! I use a Google Custom Tab to open the authentication link in App if they are running a newish version of Android using this code in my main Activity. [i]Uri uri = Uri.parse("https://www.bungie.net/en/Application/Authorize/1234567890"); [b]<--- your auth link here[/b] CustomTabsIntent.Builder intentBuilder = new CustomTabsIntent.Builder(); CustomTabsIntent customTabsIntent = intentBuilder.build(); customTabsIntent.launchUrl(this, uri);[/i] In my Manifest file I add some declarations to register a URL callback so that I get notified when the auth has complete. [i]<activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> [b]<--- important section to add[/b] <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.BROWSABLE" /> <category android:name="android.intent.category.DEFAULT" /> <data android:scheme="yourURISchemeNameHere" /> </intent-filter> </activity>[/i] You then specify your redirect URL on Bungies Application page to "yourURISchemeNameHere://token" Then finally back in your main Activity's onCreate add this code: [i]Intent intent = getIntent(); Uri data = intent.getData(); if (data != null) { String uriString = data.toString(); }[/i] uriString will have the code within it as a URL parameter. Do some String parsing to look for code= and pull out the rest and this is your code to request your Access Token
