Is it possible to develop Android apps using only the Android SDK, without any IDE like Android Studio?
Yes, see the Google SDK documentation.
However, with the current toolchain and documentation it'll be an uphill struggle. I'm trying to do this too (for a dev who lives in Vim and Unix tools, Android Studio is needlessly slow and bloated).
The main issues I've found so far:
The SDK documentation gives instructions to create an Ant-driven project, but the SDK is now geared towards using Gradle. If you're working through the Google documentation in a linear fashion, you'll find subsequent lessons have you issue Gradle build instructions. For your Ant-built project.
There is very little documentation on how to actually create a Gradle-built project from the command line. The command line I use is:
android create project --target android-22 --name MyProjectName --path my_project/ --activity MyProject --package com.example.android.myproject --gradle --gradle-version 1.2.2
The --gradle-version
actually refers to the Gradle Android plugin version, not the version of Gradle itself. Finding this out wasn't easy.
Even if you get it to create a project properly, it probably won't build without further manipulation. One of the generated files (project/build.gradle
) has an invalid directive name (runProguard
- I'm guessing it's now deprecated). That must be changed to minifyEnabled
before the project will build. And using the Gradle plugin 1.2.2, the file project/gradle/wrapper/gradle-wrapper.properties
has the Gradle distribution incorrectly listed as gradle-1.2.2-all.zip
. This should be gradle-2.2.1-all.zip
.
These are files generated by the SDK with errors.
The documentation is focussed on IDE-based development. Once you get past the initial few pages on creating and managing a project using the command line, it's very IDE-focussed.
Instructions on things like changing an app Theme are difficult or impossible to follow as they omit steps that the IDE performs for you.
In general, fully IDE-less development for Android (at least in Java, using the official SDK) is very painful. And my personal opinion is that IDE-based development is equally painful (slow, bloated, ugly on high-DPI screens under Linux and evidently full of magic that's a pain to replicate on the command line).
Edit: I should add that the above refers to using SDK tools v24.2, SDK Platform-tools v22, SDK Build-tools v22.01 and Android API 22 (5.1.1).
