    val memoryInformation = ActivityManager.MemoryInfo()
    activityManager.getMemoryInfo(memoryInformation)
    val totalMemory = memoryInformation.availMem
    val megaByte = totalMemory / (1024L * 1024L).toInt()
    if (Build.VERSION.SDK_INT == Build.VERSION_CODES.M && (megaByte < 300))
    {
        Toast.makeText(this , "Insufficient Memory to run the application" , Toast.LENGTH_LONG)
            .show()
    } else
    {
        Log.e("Memory size" , "checkLowMemory: $megaByte")
    }
 }

ViewBinding View binding is a feature that allows you to more easily write code that interacts with views. Once view binding is enabled in a module, it generates a binding class for each XML layout file present in that module. In most cases view binding replaces findViewById Setup instructions View binding is enabled on a module by module basis.  To enable view binding add the following code in build.gradle (Module) file. buildFeatures { viewBinding true } If you want a layout file to be ignored while generating binding classes, add the following attribute to the root view of that layout file.  < RelativeLayout xmlns: android ="http://schemas.android.com/apk/res/android" xmlns: tools ="http://schemas.android.com/tools" android :id ="@+id/RelativeLayout01" android :layout_width ="wrap_content" android :layout_height ="wrap_content" tools :viewBindingIgnore ="true" > </ RelativeLayout > Usa...

Overview Android DataBinding is a way to attach user interface with business logic. DataBinding eliminates the way of manual intervention. If there is a change in data, user interface will update automatically. This reduces a lot of boilerplate codes. Steps to follow Enable databinding in build.gradle (Module) in the android section plugins { id 'com.android.application' id 'kotlin-android' id 'kotlin-android-extensions' id 'kotlin-kapt' } buildFeatures { dataBinding true } /*or*/ dataBinding { enabled true } Import the dependency in build.gradle (Module) in the dependencies section kapt "com.android.databinding:compiler:3.1.4" Enable DataBinding in layout. <? xml version ="1.0" encoding ="utf-8" ?> <layout xmlns: android ="http://schemas.android.com/apk/res/android" > <data> <variable name ="user" type =...

Overview SSLSocketFactory is used to create secure sockets. Steps to follow First you have to create a key store. Open command prompt using Administrator login. Type " cd C:\Program Files\Java\jdk-14\bin ". Type the below command keytool -genkey -v -keystore my-key.keystore -alias my-key-alias-keyalg RSA -keysize 2048 -validity 10000 Follow the steps given in the screenshot: For - keyalg you can use RSA, DSA, EC to generate asymmetric key pair or use DES, 3DES to generate symmetric key pair. Then you have to generate a certificate Open command prompt using Administrator login. Type " cd C:\Program Files\Java\jdk-14\bin ". Type the below command keytool -certreq -alias "my-key-alias" -file mycertreq.csr -keystore my-key.keystore Follow the steps given in the screenshot. Note: The password , alias name , keystore name must be the same which you used while creating the keystore . An example of creating a subclass of SSLSocketFactory class TLSSocketFact...
