Fragmented - Android Developer Podcast

Philip Simpson, rockstar developer of the amazing Pocket Casts Android Application, joins the show. They discuss the growth of Shifty Jelly, tools for scaling and becoming effective indie app developers. They delve into audio software and other tech topics. They also cover the development journey of Pocket Casts, tips for indie app developers, backend servers, managing support requests, troubleshooting challenges, and diagnosing memory leaks with Leak Cannery.

In the final part of this two-part segment, we continue our talk with Jake Wharton. We dive right into the topic of testing. Jake then talks about his approach to testing apps in Android and the different languages that he finds interesting. We then move on to RxJava, NotRxAndroid, SqlBrite and many other libraries and topics to round out this great second episode. Again, we'd love to thank Jake for joining us here on the Fragmented Podcast show; it has been an honor. We hope you enjoy it as much as we did.

The hosts discuss tips for efficient image rendering in Android, including bitmap sizes and allocation, reusing bitmaps, and downsampling bitmaps. They also explore caching techniques and dive into different image libraries available for Android developers, such as Picasso. They compare Glide and Picasso, and discuss the Ion library for networking and image loading. The hosts touch on JSON libraries, the Parcel tool, and wrap up the show with their picks for the week.
