I implemented a bottom navigation bar with multiple fragments. When selecting each view, I added the fragment to the back stack with transaction.addToBackStack(null). However, when I pressed the back button the fragments switched but the menu item in the navigation bar would not highlight.   Apparently, Material design guidelines state “On Android, the Back button does not navigate between bottom navigation bar views.”   As a result I needed to remove the call to addToBackStack as the proper behavior is for the back button to go to the previous app or activity.

To determine where the Android SDK folder on your computer is located open Android Studio. Press the Android Studio menu in the toolbar and search for “Android SDK” or navigate there via Appearance & Behavior, System Settings, Android SDK. The location of the folder is located in the text box near the top that says “Android SDK Location”. By default the Android SDK location is stored at “/Users/[USER]/Library/Android/sdk” or at “/Library/Android/sdk/”.

Google gives an overview of what expansion APK files are along with some sample code. However, getting started can be tricky. Here is an easier to understand set of instructions for importing the necessary libraries as modules in Android Studio. The following instructions were tested with Android Studio version 2.2.3 on a mac. Note that on a mac the Android sdk folder is at /Library/Android/sdk/ or at /Users/[USER]/Library/Android/sdk/.

To get the .csv report go to Order History Reports and select the “Items” Report Type, along with a start and end date, or simply press one of the “Quick Set Options” such as “Last Year”.

It is good practice to run your go web server in a non-root environment. However, if your web server isn’t root then it can’t bind to port 80. One solution is to use nginx as a proxy to listen on ports 80 and 443 for http/https traffic and forward them to your go server running on a higher port such has 8000, 8080 or 9000.   Digital Ocean has a good tutorial on how to install Nginx.

If your WordPress server works normal for a few days and then shows the error message “Error Establishing a Database Connection” it is most likely due to heavy load to your website that your server could not handle. The extra load could be due to a lot of traffic from an incoming link or it could be a malicious actor attempting to brute force their way into your WordPress installation. If you have control of the server such as on AWS or Digital Ocean you can ssh into the server and restart the machine.

Have you ever wanted to create a custom keyboard shortcut for a Mac App but the app you’re using doesn’t let you modify their keymap or perhaps their interface is too cumbersome to use? For example, if you are running the Google Chrome internet browser on your Mac and you want to refresh the page with the F5 key, there is no way to do that from within Google Chrome.

I have a Sony STRDN1060 Receiver and although I have a universal remote (Logitech Harmony 650) which I like very much, I find myself still using the Sony remote to switch inputs. However, the default inputs labels of SAT/CATV, GAME, SA-CD/CD didn’t really match up to the actual devices I had hooked up to those HDMI ports. I have a TiVo, chromecast, and an Apple TV. In order to simplify my life so I don’t have to remember which input matched up to which device, I used a label maker (Brother Printer PTD600 PC) to change the labels on the remote.

Sometimes MySQL seems to have trouble starting up automatically. Even though I have the setting for MySql set to start up automatically via the checkbox “Automatically Start MySQL Server on Startup” in System Prefrences - MySQL.

When Apple Search Ads launched in October 2016 it only displayed ads in the United States. However, it expanded to multiple English speaking countries on April 25, 2017 to include the United Kingdom, Australia, and New Zealand. Each country is represented by a different storefront and to get your ad to display in each storefront you need to create a separate campaign for each country.   By August 1, 2018, Apple Search Ads expanded to include France, Germany, Italy, Japan, Mexico, South Korea, Spain and Switzerland.

Swift 3 removed CurveEaseInOut so you will get the error message “‘CurveEaseInOut’ is unavailable: use [] to construct an empty option set” Replace UIViewAnimationOptions.CurveEaseInOut with [.curveEaseIn, .curveEaseOut]

Swift 3 removed CGSizeMake. You will get the error message “‘CGSizeMake’ is unavailable in Swift”. To resolve this replace: CGSizeMake(100, 200) with CGSize(width: 100, height: 200)

If you are using swift and CocoaPods you may get the following warning after running pod install or pod update: [!] The target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/…. This can lead to problems with the CocoaPods installation The warning message then gives the following two suggestions: Use the $(inherited) flag, or Remove the build settings from the target. To implement the first suggestion of using the `$(inherited)` flag follow the steps below:

After installing Xcode 9 and migrating to Swift 4 from Swift 3 I received this warning: The use of Swift 3 @objc inference in Swift 4 mode is deprecated. Please address deprecated @objc inference warnings, test your code with “Use of deprecated Swift 3 @objc inference” logging enabled, and then disable inference by changing the “Swift 3 @objc Inference” build setting to “Default” for the “AppName” target.  

After converting my Swift 3 project to Swift 4 I received the warning: ‘substring(from:)’ is deprecated: Please use String slicing subscript with a ‘partial range from’ operator. The old Swift 3 code was let range = str.range(of:"Some ") let index = range!.upperBound let subStr = str.substring(from: index) The new Swift 4 code for substring is: let str = "Some String" let range = str.range(of:"Some ") let index = range!

Disclaimer: I am not a lawyer. This is not legal advice, this is for information purposes only. Consult an attorney for legal guidance.   If your iOS app is simply using ATS or HTTPS to communicate with an external server then your app is using Encryption. As such you may need to submit a year-end self classification report to the US government. This is far-reaching as Apple is pushing to require ATS in all apps.

For iOS 11 Apple stated that the App Store will have Enhanced Search which will include “developers, in-app purchases, categories, editorial stories, tips and tricks, and collections”. In the past, if you searched for a developer name the App Store would show those developers’ apps in the search results.   In iOS 11 if you search for a developer by their name, the first search result will feature a page dedicated to that developer with a collage of icons generated from their apps.

Apple allows apps developers to host their In-App Purchase Content on Apple’s servers. To set up Content Hosting you will need to use iTunes Connect, Xcode and the Application Loader. The IAP must be non-consumable to take advantage of content hosting. iTunes Connect Go to your app in iTunes Connect, then select Features, In-App Purchases. Create a new In-App Purchase or select an existing one. In the Content Hosting section, press “Turn On Content Hosting”.

If you want to play the sound from a video or audio clip even when the iPhone or iPad device is muted you can use AVAudioSession to accomplish the task. This will make your app work similar to YouTube. You will want to set the AVAudioSession category to AVAudioSessionCategoryPlayback. The session is a singleton so you only need to set it once, either shortly after app launch or prior to your audio or video playing.

First go to https://itunesconnect.apple.com/ and login. Second, select the “Users and Roles” icon. Third, press the + plus button to the right of User () to add a new user. Enter their name and email address. Select the role or roles to give the new user. Lastly, select which email notifications they should receive.   If you are hooking up a cloud reporting service such as App Annie or appfigures to your iTunes account, you should probably create a new user with the Sales and Reports Roles only.

Apple Search Ads is one of the many new introductions to the App Store for 2016. The new search ads allow developers and marketers to promote their iOS Apps at the top of App Store search results by bidding on search keywords.   You bid on how much you are willing to pay for a user to tap on your ad. For the most part you want to keep the average cost per acquisition (Avg CPA) below the lifetime value of a user.

iOS 7 introduced Dynamic Type which allows the user to specify the font size in Settings. The easiest way to support dynamic type is to use one of Apple’s pre defined Font Text Style’s below.

This tutorial shows you how to open another iOS app from within your iOS app or from the safari browser using a custom URL scheme. Beginning with iOS 9, you must whitelist the apps you want to open. If you do not, you will get the error -canOpenURL: failed for URL: “customURLScheme://” – error: “This app is not allowed to query for scheme”. If you get this error skip to the beginning of step 3.

These instructions are for localizing the information contained in the Info.plist. This includes the app’s name which is displayed on the user’s home screen under your app icon. In Xcode go to File, New, File.. Select iOS (or the platform you are working with), Resource, Strings File, Next. Name the file InfoPlist.strings (case sensitive). If you only plan on having one App name for your project then I recommend placing the file in the same directory as your Localizable.

Localization is the translation of the app’s user interface into locale specific languages.  In order to support localization we will use a strings file. Creating a Localizable.strings file I like to place the strings file in its own folder called “Resources”. In Xcode, Select “File”, “New”, “File…” In the template picker select the “Resource” for the appropriate OS.  Select “Strings File”. Name the file “Localizable.strings”.  This is the iOS default naming convention, don’t name it something else unless you want to refer to it by name every time you need to reference it.

Promo codes allow you to give away your paid app for free. They are mainly used for sending your app to journalists or bloggers so that they can review your app at no cost to them. You can also send them to your friends or reward those who made some contribution to the apps development. Developers can generate up to 100 promo codes per version. Each code expires 28 days after generation or when you release a new version of the app, whichever comes first.

Apple’s documentation states that “Adding support for universal links is easy. There are three steps you need to take”. However, there is much more to it than that. Here is what you really need to do.   apple-app-site-association file Create the apple-app-site-association file and place it at the root of your webserver or the .well-known subdirectory. { "applinks": { "apps": [], "details": [ { "appID": "9JA89QQLNQ.com.apple.wwdc", "paths": [ "/wwdc/news/", "/videos/wwdc/2015/*"] }, { "appID": "ABCD1234.

File..New File From the appropriate platform, choose Resource, Strings File Name it “Localizable.strings”. Add your key value pairs as such: "HELLO_WORLD" = "Hello World!"; In code add your localized string with: Swift NSLocalizedString("HELLO_WORLD", comment: "")</pre> Objective-C NSLocalizedString(@"HELLO_WORLD", nil); To add additional languages go to your project..Info..Localizations.
