Android/Firebase - store firebase data in background for use on UI instead of loading new data when an activity is started

Android/Firebase - store firebase data in background for use on UI instead of loading new data when an activity is started



I would like to know, what is the best way to store data from a firebase data in the background of my android app so that it can be used on the UI at any time.


Currently I am accessing the database and then applying the data to the UI within public void onActivityCreated in my fragment but it takes a few seconds to load the data meaning that every time the user accesses this fragment, they are sat waiting for the data to load.

I feel like it would be better for the user if the data was stored somewhere in the background so it could be used instantly at any time in order to reduce loading times but I'm not really sure how to go about it.

Any help appreciated, thanks.

I discovered what I was looking for was the singleton pattern.

How can temperature be calculated given relative humidity and dew point?

How can temperature be calculated given relative humidity and dew point? While looking into the better indicator of how miserable it feels outside, either dew point or relative humidity, I came across this statement: The optimum combination for human comfort is a dewpoint of about 60 F and a RH of between 50 and 70% (this would put the temperature at about 75 F). Source: http://www.theweatherprediction.com/habyhints/190/ This led me to this calculator that will calculate the temperature given relative humidity and dew point - for example a dew point of 70 degrees F and a relative humidity of 90% results in a temperature of 73.11 degrees F. The web site for this calculator says the values are based on the August-Roche-Magnus approximation and gives the following equation to calculate temperature: $T =243.04 Large fracfrac17.625 TD243.04+TD-lnleft(fracRH100right)17.625+lnleft(fracRH100right)- frac17.625 TD243.04+TD$ Given the equation I'm still having a hard time figuring out...

I have a recursive function to validate tree graph and need a return condition

I have a recursive function to validate tree graph and need a return condition I have a tree graph. Each node has attribute 'amount'. The rule governing the attribute value of root is this, The root 'amount' value is the sum of the 'amount' attribute of each of it's children. This continues to the last node with children. In other words this tree's attributes are unlike a sum tree, because the root node is not the sum of each node in the tree. Here is a toy example as graph G: nodedict = 'apples': 'amount': 5.0, 'bananas': 'amount': 10.0, 'tomato': 'amount': 50.0, 'total_fruits': 'amount': 15.0, 'total_vegetables': 'amount': 9.0, 'carrot': 'amount': 3.0, 'squash': 'amount': 6.0, 'total_fruits_and_vegetables': 'amount': 74.0 edgelist = [('total_fruits', 'apples'), ('total_fruits', 'bananas...
