Elixir Cheatsheet - Elixir in Brief
Elixir is a dynamic functional compiled language that runs over an Erlang Virtual Machine called BEAM. Erlang and its BEAM is well known for running low-lattency, distributed and fault-tolerant applications. Elixir was designed to take all that advantages in a modern coding language. Elixir data types are immutable. In Elixir a function is usually described with its arity (number of arguments), such as: is_boolean/1. File Types 🔗 .exs => Elixir script file .

How to get currently running applications in android ?
Use this code in your app’s `src/MainActivity.kt’ file. import android.app.ActivityManager import android.app.ActivityManager.RunningTaskInfo import android.content.Context import android.os.Bundle import android.widget.TextView import androidx.appcompat.app.AppCompatActivity import java.util.* class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) title = "KotlinApp" val textView: TextView = findViewById(R.id.textView) val activityManager = getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager val recentTasks: List<RunningTaskInfo> = Objects.requireNonNull(activityManager).getRunningTasks(Int.MAX_VALUE) for (i in recentTasks.indices) { textView.text = "Application executed: ${recentTasks[i].baseActivity!!.toShortString()}ID: ${recentTasks[i].id}" } } } Make sure you have a TextView with id textView in your XML layout.
Should I use Swift or Objective-C to learn iOS development ?

How do you animate the change of background color of a view on Android ?
The idea is to use this code snippet. ColorDrawable[] colorDrawables = { new ColorDrawable(Color.RED), new ColorDrawable(Color.BLUE), new ColorDrawable(Color.GREEN) }; TransitionDrawable transitionDrawable = new TransitionDrawable(colorDrawables); textView.setBackground(transitionDrawable); transitionDrawable.startTransition(2000); In this code snippet, we created a list of colorDrawables, then feed them to the TransitionDrawable. And now we have an animating color change, so we pass it to the setBackground to get the animating colors in the background. Got the idea ? let’s create a complete code example.
