A more descriptive title would be, “Using ADB logcat outside of ADT, Eclipse, or Android Studio to debug your Android app installation errors.” Did you try to install the app in your Android device, but got the annoying “Unfortunately, [app name] has stopped”? If so, then you need to run ADB logcat to find out why. Logcat allows us to read the logs that are automatically running in the background when we run the program. So when the app quits suddenly, we can read the messages along the way and pinpoint when it went south. Here are the steps to implement logcat. Continue reading
I decided to try npm (nodejs) and see how it could streamline my workflow. If you’ve been using Cordova or PhoneGap, you probably already have npm installed – you used npm to install either one in the first place. But it can do so much more.
If you want to update your version of Cordova to the latest version, or you want to revert to an earlier version (to test or debug), here are the steps to follow. I also have instructions on updating the plugins and platform versions here.

You can install your app on your iOS device and monitor its usage on your desktop monitor, including console feedback. Here’s how. Continue reading
You can add a versioning control system to track and manage your project’s assets with Git locally — you don’t need to upload it to git.com. Here’s how.
Download Git from http://git-scm.com. It will detect your OS and provide the correct download for it. For my Mac, it was version 188.8.131.52.
The Mac version downloaded a dmg file to my Downloads folder. Double-click to open it, then double-click on the pkg file. (If your preferences prevent you from opening a file from an unidentified developer, then hold down Control, right-click on the pkg icon, and select open.) The Installer should appear; click to continue through the few steps, including providing your admin password. You’ll find a drive icon for the Git dmg package; right-click and select to Eject. (I believe “dmg” is short for “disc image.”) Continue reading
One of the checks you should make before creating your apk file for testing or uploading to an Android-based app store is the Run Lint command in Eclipse. This is found when you right-click on your project name in the Project Explorer, and select Android Tools > Run Lint…
The Lint Warnings view will show various performance, correctness, security, and other Android-environment-specific problems that may give rise to your app not loading or working in your device. (You would not use Lint to check for the validity of your HTML; you would use Validate for that.) Continue reading
