APK Information Script

Why?

To collect interesting information about your Android APK:

• APK size in bytes
• classes.dex size in bytes
• # methods (useful for monitoring the magical 65k dex limit)
• # classes

How?

Run this script in any folder containing one or more .apk files.

Result (normal mode):

user$ apk-stats.sh
classes	methods	dex-bytes	apk-bytes	apk
790	6451	9027848	1080992	SomeApp-production.apk
760	6461	9027860	1081028	SomeApp-debug.apk
700	6661	9027848	1081010	SomeApp-stage.apk

Team City Support

To collect this information from a Team City job it supports TC's system messages which you in turn can use to create nice custom charts for your project/job configuration.

The custom metrics are reported like this:

Result (Team City mode):

apk-stats.sh teamcity
Team City system messages enabled!
classes	methods	dex-bytes	apk-bytes	apk
790	6451	3027848	5800992	SomeApp-production.apk
##teamcity[buildStatisticValue key='classes-SomeApp-production.apk' value='790']
##teamcity[buildStatisticValue key='methods-SomeApp-production.apk' value='6451']
##teamcity[buildStatisticValue key='dex-size-SomeApp-production.apk' value='3027848']
##teamcity[buildStatisticValue key='apk-size-SomeApp-production.apk' value='5800992']

Team City will automatically pick up these values and you'll see them under the job's Parameters tab and under Reported statistic values. Click on this graph to see the trend.

Custom chart setup

For a nice graph of these metrics on your project's Statistics tab change your Team City master's .BuildServer/config/projects/:yourProject/pluginData/plugin-settings.xml to something like this:

<settings>
        <custom-graphs>
                <graph title=".dex Information">
			 		<properties>
			    		<property name="axis.y.max" value="65536"/>
						<property name="axis.y.min" value="0"/>
						<property name="height" value="300"/>
			  		</properties>
                	<valueType key="methods-SomeApp-production.apk" title="Methods (Production)" buildTypeId="project_SomeJob"/>
                	<valueType key="classes-SomeApp-production.apk" title="Classes (Production)" buildTypeId="project_SomeJob"/>
                </graph>
                <graph title="APP Size" format="size">

                	<valueType key="apk-size-SomeApp-production.apk" title=".apk (Production)" buildTypeId="project_SomeJob"/>
                </graph>
        </custom-graphs>
