  • Import Project:
  • Start Android Studio and close any open Android Studio projects.
  • From the Android Studio menu select File > New > Import Project.
  • Select the location where you placed your project files.
  • Press ok and wait for all the processes to finish

Sometimes, the Gradle Build fail, here are some additional steps you can take:

Android Studio might ask you to do download some additional SDK components in the ‘messages’ tab, simply follow the instructions to install and download the additional components to fix this

  • Make sure the app is targeting at least lollipop and that all the libraries are linked:

Libraries(.jar) from the libs folder .All the Gradle defined libraries are linked (as found in app/build gradle)  Make sure to wait until all loading is complete before manually (re)adding any modules and/or libraries!

  • Changing package name & exporting:

Before we can submit our app to the play store, you have to change your package name and compile your application.

  • Changing the package name:

The package name is you apps unique identifier. It is mentioned in your manifest and all your java files, and it is your project structure.

Create a new package (usually something like: com.mycompany.myapp) now drag the content from the com.utech.allinonevideodownloader app package (sub packages and files) into the new package. Also replace in strings and textual occurrences.

After you have done this, replace all the occurrences of com.utech.allinonevideodownloader with your new package name using Ctrl + Shift + R (Cmd +Shift +R on OSX).

If everything went correctly, packages in the project explorer should be changed into, just as the package name in the manifest.

  • Compiling All video Downloader App:

In this step we are going to create an apk, and you can run it on your phone!

  1. Make sure your project is selected.
  2. Click Build>Generate Signed APK.
  3. Follow the on screen instructions to create a key store, this is only required once save the key store on a safe place, otherwise you won’t be able to update your app.
  4. Export the android application to a location (desktop for example).

You can now put this file: Xxx.apk on your phone, you will be prompted to check the unknown sources checkbox if you have not check edit already, you users won’t have to do this if they download the app from the google play store. Run directly, you can also connect your phone to your PC and run the app directly using Run>Run”App” (you can also debug using Run & Logcat).

This is assuming you already have Android Studio (version 2.2 at the time of writing), its Android SDK (version 24) and Java SDK (at least 7) installed.

Step 1: Setup the Kotlin Plugin in Android Studio

In order to ensure Android Studio support Kotlin, the first thing is to install the Kotlin Plugin for your Android Studio.

Android Studio → Preferences… →Plugins → Browse Repository → type “Kotlin” in search box → install

Plugins Browser, where you can find Kotlin Plugin for you to install.

That’s all the generically applied to your Android Studio. Only needed to do once per installation of Android Studio.

Step 2: Add Kotlin classpath to project Build.Gradle

For gradle to have Kotlin support, add the two classpaths below, i.e. Kotlin-Gradle-Plugin and Kotlin-Android-Extensions. Also in this file I setup the variable to define Kotlin version, that could be shared by all.

buildscript {
    ext.kotlin_version = “1.1.1”
    ext.supportLibVersion = “25.3.0”
    repositories {
    dependencies {
        classpath ‘’
        classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version”
        classpath “org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version”

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

Step 3: Add Kotlin library and apply Kotlin Plugins in your module Build.gradle.

In the module that will use Kotlin, you will add the Kotlin library into it’s Build.gradle. Also remember to apply both the Kotlin Android and it’s extension plugin to your project (I often forgot this, after add the library).

apply plugin: ‘’
apply plugin: ‘kotlin-android’
apply plugin: ‘kotlin-android-extensions’

android {
    // … various gradle setup

dependencies {
    compile fileTree(dir: ‘libs’, include: [‘*.jar’])
    testCompile ‘junit:junit:4.12’
    compile “$supportLibVersion”
    compile “$supportLibVersion”
    compile “org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version”

Step 4: Ready to go…

Now you have setup Kotlin for your app development, you could start writing Kotlin code (in .kt extension). Another way is convert your Java file to Kotlin, using Shift-Alt-Cmd-K or Shift-Shift + search Convert Java File to Kotlin File.
