Firebase Crashlytics Android Example

-
Firebase Crashlytics is a lightweight, realtime crash reporter that helps you track, prioritize and fix stability issues that erode your app quality. Crashlytics saves you troubleshooting time by intelligently grouping crashes and highlighting the circumstances that lead up to them.

Prior to Firebase Crashlytics, Google offered Firebase Crash Reporting (FCR), for app crash monitoring and reporting. Although FCR did it's job (monitoring crashes) it was a hack and it has since been deprecated in favor of Crashlytics.

Reasons to use FIrebase Crashlytics over Firebase Crash Reporting

  1. Real time crash reporting : FCR could take up to 30 mins or more before an error could be reported (via email).
  2. Intuitive Dashboard Report interface : the dashboard of has been improved
  3. un-obfuscated stack trace: If you used Pro Guard or DexGuard to obfuscate your code, firebase crash reporting mandates the uploading of a "mappings.txt" file to the FCR console in order to decode stack trace. However, with Crashlytics, I bring you good news, there's no need to upload a "mapping.txt" file. Crashlytics supports ProGaurd and DexGuard and also ... wait for it...  Automatic deobfuscation of stack trace.

How to Add Crashlytics SDK to your App

1. Add your app to Firebase Console. Tools -> Firebase -> Add New Projecy

2. Add the code below to build.gradle(Module : app)

dependencies {
   implementation 'com.crashlytics.sdk.android:crashlytics:2.9.5'
   ...
}
apply plugin: 'io.fabric'

3. Add the code below to build.gradle(Project : AppName)
allprojects {
    repositories {
        ...
        maven {url 'https://maven.fabric.io/public'}
    }
}

4. click Sync Now and your all set

-
Hey, so you want to let your app listen to Clipboard data? Android does not support listening to Clipboard changes with Broadcast Receiver, obviously due to security reasons - evil apps can't listen when you copy sensitive info, such as password, credit card info etc without the doing the extra work of implementing it themselves. However, there's a work-around by listening to when a new Clip Data is added to ClipBoard Manager. In the example below, your app will be able to listen to copied texts

Kotlin ArrayList and Loops Example

-
Kotlin ArrayList Kotlin ArrayList is also very similar to Java Arraylist . ArrayList<T> is the resizable-array implementation of the  List  interface. The ArrayList class has only a few methods in addition to the methods available in the List interface . val myArrayList = arrayListOf("John", "Fred", "McKinsey", "Morgan", "Sarah") //an arraylist of my friends val newFriendList = arrayListOf("Musa", "Victor", "Timothy") myArrayList.add(0, newFriendList[0]) for (e in myArrayList){ print("$e -") } // Musa -John -Fred -McKinsey -Morgan -Sarah myArrayList.removeAt(0) // removes 'Musa' which is at postion 1 val allOfMyFriends = myArrayList + newFriendList for(element in allOfMyFriends){ print("$element -") } // John -Fred -McKinsey -Morgan -Sarah -Musa -Victor -Timothy println(allOfMyFriends.size) // 8 println(allOfMyFriends.isEmpty) // false val isRemoveFredSucces...
