You can define the signing configuration to sign the apk in the build.gradle file.
You can define:
storeFile : the keystore file
storePassword: the keystore password
keyAlias: a key alias name
keyPassword: A key alias password
You have to define the signingConfigs block to create a signin...
You can define the signing configuration in an external file as a signing.properties in the root directory of your project.
For example you can define these keys (you can use your favorite names):
STORE_FILE=myStoreFileLocation
STORE_PASSWORD=myStorePassword
KEY_ALIAS=myKeyAlias
KEY_PASSWOR...
You can store the signing information setting environment variables.
These values can be accessed with System.getenv("<VAR-NAME>")
In your build.gradle you can define:
signingConfigs {
release {
storeFile file(System.getenv("KEYSTORE"))
storePasswo...
We use the null function to check if a given Map is empty:
> Map.null $ Map.fromList [("Alex", 31), ("Bob", 22)]
False
> Map.null $ Map.empty
True
There are many querying operations on maps.
member :: Ord k => k -> Map k a -> Bool yields True if the key of type k is in Map k a:
> Map.member "Alex" $ Map.singleton "Alex" 31
True
> Map.member "Jenny" $ Map.empty
False
notMember is similar:
&g...
Inserting elements is simple:
> let m = Map.singleton "Alex" 31
fromList [("Alex",31)]
> Map.insert "Bob" 99 m
fromList [("Alex",31),("Bob",99)]
The Data.Map module in the containers package provides a Map structure that has both strict and lazy implementations.
When using Data.Map, one usually imports it qualified to avoid clashes with functions already defined in Prelude:
import qualified Data.Map as Map
So we'd then prepend Map funct...
In Normal Mode, commands can be entered by direct key combinations (typing u to undo the last change, for example). These commands often have equivalents in 'ex' mode, accessed by typing a colon :, which drops you into a single-line buffer at the bottom of the Vim window.
In 'ex' mode, after typing...
You define a keyword argument in a method by specifying the name in the method definition:
def say(message: "Hello World")
puts message
end
say
# => "Hello World"
say message: "Today is Monday"
# => "Today is Monday"
You can define multip...
You can define a method to accept an arbitrary number of keyword arguments using the double splat (**) operator:
def say(**args)
puts args
end
say foo: "1", bar: "2"
# {:foo=>"1", :bar=>"2"}
The arguments are captured in a Hash. You can manip...
This is very similar to using an Application subclass and overriding the attachBaseContext() method.
However, using this method, you don't need to override attachBaseContext() as this is already done in the MultiDexApplication superclass.
Extend MultiDexApplication instead of Application:

Automapper can be installed from nuget running the following command in Package Manager Console:
Install-Package AutoMapper
Then it can be included in different files within the project it has been installed to by using directives:
using AutoMapper;
Unlike a parallel for-loop (parfor), which takes the iterations of a loop and distributes them among multiple threads, a single program, multiple data (spmd) statement takes a series of commands and distributes them to all the threads, so that each thread performs the command and stores the results....
Using Alternatives
Many Linux distributions use the alternatives command for switching between different versions of a command. You can use this for switching between different versions of Java installed on a machine.
In a command shell, set $JDK to the pathname of a newly installed JDK; e.g....
Given a DataFrame with MultiIndex columns
# build an example DataFrame
midx = pd.MultiIndex(levels=[['zero', 'one'], ['x','y']], labels=[[1,1,0,],[1,0,1,]])
df = pd.DataFrame(np.random.randn(2,3), columns=midx)
In [2]: df
