POBuild configuration management in Android / Intellij / Jenkins
text
Body
copied!<p>This question might be subjective, but I think Stackoverflow is still the best place to ask:</p> <p>The problem domain is "advanced Android programming". I do not need information how to set up a single Android project, how to use library projects, or how to use ANT to build a normal project.</p> <p>Assume you got a running App, an ordinary Android project (IDE of choice is IntelliJ, but that should not really matter) build by Jenkins / Ant / Proguard. The result of this build is a final APK you would put in the Play store.</p> <p>Now imagine you need this App as a free and a paid version. No problem so far, simply put all shared code into a library project, and create two child projects, one with an App.java enabling license checks, the other one e.g. limiting the usage.</p> <p>Now imagine you want to target Amazon as well, maybe have a press release version, etc. So your code starts to diverge, with still a lot of stuff shared, but certain parts are specific to e.g. the market you target.</p> <p>In C# there are "conditional compilation statements", like "IF PLAY_STORE ...". Is there anything similar for Java / Android. Also, do they play nice with ANT and the build process.</p> <p>But I am not limited to conditional compilation. The "one project per market" approach is a different one. I am just trying to get a feeling of how you manage these various "build configurations" in a manner that is sustainable. Meaning it works for 15 projects, targeting 3 markets in 2 flavors (FREE and PAID). I hope you see what I am hinting at. The code is very very similar for all Apps, but with the example above I will have 90 different APKs - with these numbers the "manually commenting in source code only needed by this build, etc" just does not cut it anymore.</p> <p>So any tips, tools, search words, experiences with these problem domain (e.g. MAVEN, would it help me with any of it, or is ANT + scripts generating build.xml be better). Another example, if I have a "real" Android project for all target markets, this would allow me to do almost anything. But of course, on the downside, if I add a new page in the lowest level (e.g. a imprint page) I would need to go into 90 Manifest.xml to add the page...</p> <p>Thanks for any help with this, Chris</p> <p>PS: I will add some links I find regarding this topic at the bottom, if anybody comes across this question while there are no answers, this might be a "first read this" section</p> <p><a href="http://www.asyncdev.net/2011/02/android-dev-prod-builds/" rel="noreferrer">http://www.asyncdev.net/2011/02/android-dev-prod-builds/</a></p> <p><a href="http://www.slf4j.org/" rel="noreferrer">http://www.slf4j.org/</a> (related in the "put JAR in to provide IMPL" way)</p> <p>(The SLF4J is just a nice approach to reduce dependencies and provide configuration during deploy - by simply adding a different JAR. To use something like this might be overkill for your own projects, but it would be one way. E.g. for license write interface and a bit of code like SLF4J, then provide either PressRelease.jar or Productive.jar in Lib folder during build, changing how the app behaves...)</p>
