Try using default preferences with an Application context. A context is similar to the environment an application runs in on linux or windows e. Each Activity and Service has its own Context too for example screen orientation, theme, and label, etc. This the same throughout the app and will always give you the same default preferences.
Using a static method to use SharedPreference without Context Object explained here. For Kotlin and for default preference file, you can use the following code:. Learn more.

Jake Wilson. Jake Wilson Jake Wilson Active Oldest Votes. SharedPreferences are related to context. You can only reference it through a context. You can simply pass context as a parameter to your class. For example in the constructor. Sandor Sandor 1, 2 2 gold badges 15 15 silver badges 20 20 bronze badges. That was exactly what I was looking for.Well, at least, it's probably not used once your VO2max has been calculated - provided you device has that capability, which the Fenix 5 certainly does.

The sleek band is comfortable to wear all day, and the always-on display shows your stats, even in sunlight.

On the other hand, if your non Activity class is initialized and used from an onscreen Activity, you could pass that instance of the Activity to your class as a parameter in the constructor and The Garmin wearable series caters for all, allowing you to monitor your day to day activities whatever your level of fitness.

B An application can have zero or more activities. New to Python I installed python 3. Use the chart on page 4 to determine your activity class. More than likely a settings issue, and I have heard of this happening when activity class is set too high for where you actually are with fitness. It gives me my Garmin connect adjustment ofand also a running adjustment of all from my Garmin - I didn't manually enter my activity in MFP.
When I try to start an activity from a non-activity class in the same process I get an exception: "android. You can even pair the trainer with your compatible Garmin device to ride your everyday courses, activities or TrainingPeaks workouts. Fields in this class may return null so should be checked for null values prior to use. There's not a lot of documentation from Garmin except a chart that explains different levels of activity class. Aside from the saddle and handlebar height and distance, you can even adjust the crank length and Open the "Garmin" drive or volume.
Android Context in non-activity Class – The Secret of ContextWrapper
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have some little problem with android. This code will call an activity from your base adapter class.
And I don't know what you want to do. But this will give you a hint. Usually custom adapters are inner classes of an Activity subclass. This means they a reference to an outer Activity in the OuterActivity.
In this case you can start an Intent using the following code:. In other case when the adapter class is not nested, you can pass a Context reference to its constructor like it's done in ArrayAdapterSimpleAdapter and so on.
You'll have to store this reference in a field and use it to start an intent. That's possible because you don't really need an activity to start an intent. Actually you need a context. Here's the example:. Learn more. How to use intent in non activity class Ask Question. Asked 9 years, 1 month ago. Active 1 year, 1 month ago. Viewed 25k times.

S: The isAirplaneModeOn function is using depreceated method pre API 17 just for the purpose of simple example and backward compatibility. Maybe, most of the valuable stuff out there in the internet…. Both solutions works. Both have their Pros and Cons. Proxying implementation of Context that simply delegates all of its calls to another Context. Can be subclassed to modify behavior without changing the original Context.
I think, there should be some other benefit because of using this ContextWrapper. Have to explore it a bit deeper. I am sure there is. The real question is if ContextWrapper help us avoid memory leaks. Hello, Etay I think ContextWrapper can not help to avoid memory leaks. Check the ContextWrapper source. About Etay Cohen-Solal hey thanks. You saved my day. I was literally scratching my head since two hours. Bloody Context.
Yours solution is super super simple easy than other solutions. Finally i can use Context in non-activity classes and I can divide the code into separate files for easy code management. Hi, Using this way i try to sendbroadcast but getting nullpointerException. Here is a code:. Hello i am using a library function which need activity context but i am calling it using service context so.
Interesting approach of context wrapper in non activity class. Android Training. And making this i need to pass the context from the fragment itself. How should i be doing it then? And one more thing if in my fragment i use 5 common functions that i have now placed under the MyContextWrapper then for each function do i need to write like this only: new MyContextWrapper this.
This approach solves the memory leaks of dialog? So, if I close my app with a dialog open, will throw a memory leak cause my activity is closed or the wrapper will support it?

This article will cover the initial set up of a Garmin XT and Garmin Connect online, plus a few extra tips. If you are turning on your watch for the first time, there are a few steps you need to go through for initial set up.
These steps customize the watch to you. After you press the power button, the Garmin intro screen will appear, and then the initial setup will start.
The first screen asks you to select a language. You can scroll through the options using the arrow buttons on the right side of the watch. After you have made your selection, press the enter button. The next question will appear. Continue this process through all of the questions:.The challenge that many folks have found out is that different Garmin devices produce different results, and sometimes — even different results for the same person. So, I set out to put together a bit of the definitive guide to calorie calculations on Garmin fitness devices.Support: Analyzing Activities in Garmin Connect™ Mobile (Android™)
Then more recently last week I met up again with the Garmin fitness team to talk through all the painstaking details. And not unexpectedly, the accuracy level varies based on which method you use. The tests are not terribly unlike your common VO2 max test, and involve you being hooked up to tubes and wires.
The tests though are sport-specific, meaning you complete a running test to allow the Forerunner to determine running activity calories. Specifically, it evaluates the time between heart beats beat to beat to determine estimated MET Metabolic Equivalentwhich in turn is used determine actual work expenditure.
Firstbeat has published a fascinating white paper detailing the technology and accuracy rates. Meaning, over time it has a weighted algorithm to note changes in your fitness level and adjust calorie burn accordingly. This first generation algorithm is used on devices prior to this year, which are detailed in the below tables. One interesting tidbit is that they found that while this 1st generation algorithm worked really well for newer runners, it was less accurate in more advanced runners — hence some of the updates seen in the 2nd generation.
There are no plans to evolve this one-off algorithm to other devices including the next version of the FR60nor to port either Firstbeat to the FR You can convert from kilojoules to calories.

Next up is the cycling side of things. The three that are available today are:. It features a plastic portion of the strap that reads your heart rate, while the remainder of the strap is fabric. It features a fully fabric band all the way around, with snap-on connectors holding the transmitter portion to the fabric. FRXTEdgeetc…. Before I started looking into this I would have said that there were too many options, however, after understanding the different options better — and the differing levels of accuracy each one offers, I have a better grasp on why there are so many different ways to calculate calories.
Final note — Thanks to the Garmin Fitness team for their time in answering all the questions and detailed specifications of each device and calorie metric type.

According to the Garmin software update sitethis happened with version 3. Also, do you have any thoughts about the accuracy of these algorithms compared to that of their competitors? One thing I really miss from my T6 in my rowing days is the wealth of info I could pull out from workouts relating to oxygen debt, calorie usage etc.A simple Python module that allows you to log into Garmin Connect and get activity data.
