Details :

We will discuss how to run the application in Android Emulator and in Android device step by step.

In this article am taking our Voodoo Music App as an example. i.e working Sencha Touch application

Step 1: Install Sencha Cmd and create Sencha Touch Project

If your project is not created with the sencha Cmd then

Install Sencha Cmd and create Sencha Touch project

Step 2 : Build your Application

Build the application using sencha app build Command, and move all the required images and build output files to single folder.

For More Information Refer : Create, Build & Package Sencha Touch project using Sencha Cmd

Step 3: Install Android SDK

Install Android SDK in your Machine

Step 4: Create packaging Configuration Template File

Open Terminal

cd to the project root folder.

issue the following command to generate the template for native build configuration file.

This will generate andoidpackger.json file in the project root directory.

Step 5: Update the configuration file with your details

open the androidpackger.json in your favorite editor. Fill the valid configurations with the valid values


Name of the application to be displayed on the app, in my case Voodoo Music


This is the name namespace for your application, in my case


This is the version of your application, initially it will be 1.0


This is the integer version code of your application, or you can refer to it as a build number, initially it will be 1.0


Please refer to the Android Icon Sizes

Note : paths of the icons should be relative to the config file


This is location of your Sencha Touch 2 application, relative to this configuration file, in my case ./build/


This is where the built application file with be saved. Make sure that output path is not in your input path, you may get into endless recursive copying. Provide the absolute path of the output folder


This is configuration for your application. Debug should always be used unless you are submitting your app to an online store – in which case Release should be specified. For the first time to test the app in Emulator provide Debug.


This is the platform where we will be running the application. For now, it will Android Emulator, as we are building the application to run in Android Emulator


This is the location of your certificate. i.e the path of the keystore file . for the emulator it is not mandatory to mention. Will discuss this


This is the path to the Android SDK, use the absolute path


This is android API level, the version of Android SDK to use, you can read more about it HERE, In my case, I have installed Android 4.1 so am using API 16.

Be sure to install corresponding platform API in android SDK manager (android_sdk/tools/android)
Open terminal cd to the android_sdk/tools/ and issue command ./android you will be able to see Android SDK Manager where you can verify which version is installed.


An array of permissions that are used by an application, Full list of permissions for Android application can be found HERE

in my case i have used default values which were there in the template file


Indicates the device orientations in which the application can run. Options are:

  • portrait
  • landscapeLeft
  • landscapeRight
  • portraitUpsideDown

Note. If this omitted, default orientations setting is all four orientations.

Step 6: Run the Android Emulator in your machine

open command prompt cd to the tools directory inside the android SDK directory.

Issue command $ ./android – avd

you can see the avd manager ( Android Virtual Device Manager) opened.

This is a tool to create a virtual android device i.e emulator. To run your app and Unit test it.

Step 7: Run your app on Android Emulator

The final step is to run your app in Android Emulator.

Sencha Cmd helps to build the .apk file for your application and run in the Active Android Emulator in your Machine.

Cd to the project root directory, And issue the below command

$ sencha app package run <path to configuration file>.json

Path to the configuration file which is prepared in the earlier steps.

After Issuing this command you can see the app opening in Android Emulator.
