How to create a minified Sencha Touch apk?

[kevhender]

Hello,


I'm trying to figure out how to make an Android APK that is fully polished and ready for Google Play. I have an app with the following structure:

- web
  + app
  + resources
  + touch (sdk)
    app.js
    app.json
    build.xml
    index.html
    packager.json

My packager.json file looks like this:

{
    "applicationName":"My App Name",
    "applicationId":"my.package",
    "versionString":"1.0",
    "versionCode":"1",
    "icon": {
        "57":"resources/icons/icon.png",
        "72":"resources/icons/icon-ipad.png",
        "114":"resources/icons/iconX2.png",
        "144":"resources/icons/icon-ipadX2.png"
    },
    "inputPath":"./",
    "outputPath":"../build/",
    "configuration":"Release",
    "platform":"Android",
    "certificatePath":"../mycert.keystore",
    "certificatePassword":"mypass",
    "provisionProfile":"",
    "sdkPath":"c:\\Progra~2\\Android\\android-sdk",
    "androidAPILevel":"9",
    "permissions":[
                    "INTERNET",
                    "ACCESS_NETWORK_STATE"
                    ],
    "orientations": [
        "portrait",
        "landscapeLeft",
        "landscapeRight",
        "portraitUpsideDown"
    ]
}

I am running Sencha Cmd v3.0.2.288 on Windows 7 64-bit.


In a command prompt, I cd to the web folder and run:

sencha app package run packager.json

This seems to correctly build an APK file and put it into the build folder. However, the APK is 5MB, and opening the archive shows that the app has not been minified and packaged into a single app-all.js file, as I would expect.


My question is: What step am I missing to get my code build/packaged/minified before the APK packaging occurs?


I have tried this:

> cd touch
>sencha -debug app buildSencha Cmd v3.0.2.288
[ERR]           The application was last modified by an older version of Sencha CMD (0.0.0.0).  Please run 'sencha app upgrade -noframework' to update.
[ERR]           Application cmd version incompatible with this one.

Naturally, my next step was:

>sencha -debug app upgrade -noframework

My last-ditch effort was this:

Can someone please help? Thanks.

Update:

I got this command to work:

sencha app build

by copying the .sencha file that is created by the new version of Sencha Cmd app generation into my /web folder.

I also managed to figure out how the two steps (packaging and apk creation) fit together (no thanks to any Sencha documentation). After running the previous command, I changed the packager.json file's inputPath property to be the output directory from that command:

"inputPath":"build/AppName/production"

I could then run:

sencha app package build packager.json

Hopefully this will help some other poor, Sencha-documentation-lacking soul.
