Creating an Android Application Using Sencha Touch 2

I am trying to create an application using the Sencha Touch 2 tools. I have a basic application, I just want to check the creation of the application so that I can do it when I need to.

I have sencha tools, android SDK, etc.

I have a point when you run

sencha package build <configfile.json>

on the command line. After several attempts, I came to the point that it seems to have accepted this command, but does nothing, does not create an application, does not display anything on the command line, nothing.

I think I missed something, but I can’t think about it.

This is my configuration file:

{
"applicationName":"Test_app",
"applicationId":"com.testing.test_App",
"versionString":"1.0",
"iconName:":"resources\icons\Icon.png",
"inputPath":"\",
"outputPath":"C:\Users\rc\Android Development\Completed Apps",
"configuration":"Debug",
"platform":"Android",
"deviceType":"Universal",
"certificatePath":"C:\Users\rc\Android Development\Keystore\Test App\my-release-key.keystore",
"certificateAlias":"Test_app",
"sdkPath":"C:\Program Files\Android\android-sdk",
"orientations": [
    "portrait",
    "landscapeLeft",
    "landscapeRight",
    "portraitUpsideDown"
]
}
