Android Development Setup

Notes on how I set up an android development setup with minimal bloat. No IDE, no Gradle, and just using C and Makefiles.

Instructions are more or less similar to the ones found on this project: https://github.com/cnlohr/rawdrawandroid.

install packages. on arch linux

pacman -S extra/jre11-openjdk-headless
pacman -S extra/jdk11-openjdk
pacman -S android-tools

mkdir ~/android export ANDROID_HOME=~/android

Download command line tools from https://developer.android.com/studio.

Unzip contents to cmdline-tools/3.0 folder in ANDROID_HOME.

(sdkmananger will give you path warnings. trying to fix as I go).

save some keystrokes

alias sdkman=$ANDROID_HOME/cmdline-tools/3.0/bin/sdkmanager --sdk_root='${ANDROID_HOME}'

Agree to licenses:

yes | sdkman --licenses

Install stuff. Note: I'm making sure build-tools and platform-tools are the same version (29). Otherwise the rawdrawandroid session gets messed up.

sdkman "build-tools;29.0.3" "ndk;21.1.6352462" "platform-tools" "platforms;android-29"

NOTE: I ran into issues running stuff on older models like the nexus 7, so I downgraded. In the command above, I installed "25.0.0" of build-tools, and used "android-23" of platforms. In my build settings, I set the minsdk to be 17 and the target sdk to be 23. Try the modern, but if you get something related to symbol not found "fread_unlock", downgrade.

Now try cloning rawdrawandroid

git clone https://github.com/cnlohr/rawdrawandroid --recurse-submodules

Try building it with

make

Plug in properly configured device with:

make push run

On Linux, sometimes permissions are a bit screwy. Figure out the vendor id with dmesg, and put this in something like /etc/udev/rules.d/ as something like 51-android.rules, where VENDOR_ID is your vendor ID.

Unplug, and plug in again and it should work.

SUBSYSTEM=="usb", ATTR{idVendor}=="VENDOR_ID", MODE="0666"
