You also need to ensure your user interface renders quickly and runs smoothly. Your app’s user interface is your connection to the user, but creating something that looks nice is only half the battle.

Once you have this information, you’ll have a better understanding of how to perfect your app’s performance and ultimately create an app that people will love using. So along the way we’ll also look at how to use the Android SDK tools to gather more information about whatever performance problems you uncover. If you do discover a performance problem in your app, obviously you’ll want to fix it. You’ll learn how to test whether these problems are occurring in your own projects, using the tools provided by the Android SDK-plus one tool that’s already installed on your Android device. In this article, you’ll get a crash course in the common performance problems every Android developer needs to be aware of.

That is, until the negative Google Play reviews start rolling in.

It works great so my videos still have the HD quality and a nice smooth high speed playback after saving the edited video that I then import into iMovie and this works great! I use this as iMovie will only increase a video up to 2x original speed.No matter how innovative and useful your Android app is, if it’s laggy, prone to freezing, or hogs memory, no one is going to want to use it. I haven’t seen any ads yet either beyond a quick message when you open the app for first time after downloading then any time after that just a quick small message that you can click on to go to their website or continue with what you’re doing instead of annoying ads that become a nuisance. This one allows up to 8x speed increase of the imported video, so for faster ones you’ll have to save and import the video again but that’s easy enough. This one is a really good app - it’s easy to import and export videos and allows for multiple points you can put in a video to speed up/slow down certain points. I’ve tried other apps to speed up my videos and they stop at 4x speed increase, lose my HD video quality, and just don’t work that well.
