Kivy buildozer: how to deploy to specific android device - kivy

Question

I have multiple devices (both AVDs and hardware) connected to my PC, but I want to deploy to a specific device with buildozer. How can I do that if disconnecting other devices is not an option?

Answer 1

Buildozer installs to android via adb. So you have to check the documentation of adb and check how it is modified in the buildozer startup script.
http://www.appsdeveloperblog.com/install-apk-on-device-adb/
and https://pypi.org/project/buildozer/
Think the command will be like
buildozer android deploy adb --s <DEVICE_NAME>

Answer 2

As on JAN 18 2020:
It seems like buildozer 1.0.1-dev0 does not have enough flexibility to accomplish this task. Commands like buildozer android deploy adb -s <DEVICE_ID> just ignore DEVICE_ID and install apk on all available devices.
There is a handy buildozer serve command, but that is slow and requires to manually answer to all security dialogs.
Using adb directly is a fair option, e.g.:
adb -s DEVICE_ID install -r your.apk
But if there are a lot of devices (armv7 and x86), it'd be a chore to type this every time. So I ended up with a script that is placed in the project directory:
import sys
import subprocess
# TODO: edit your custom settings
ADB_EXE = "/home/your_username/Android/Sdk/platform-tools/adb"
APK_X86 = "/path/to/apk/x86/bin/your_project__x86-0.1-x86-debug.apk"
APK_ARMV7 = "/path/to/apk/armv7/bin/your_project__armeabi-v7a-0.1-armeabi-v7a-debug.apk"
DEVICES = {
# DEVICE_PSEUDO_NAME: ("DEVICE_ID", "PATH_TO_APK")
"pixtab": ("emulator-5554", APK_X86),
"pix": ("emulator-5556", APK_X86),
"nexus4": ("004a900e1b268111", APK_ARMV7),
"nomi": ("SSI1216C111031288", APK_ARMV7),
}
def run():
global ADB_EXE
global DEVICES
if len(sys.argv) == 1:
print("Please, specify device.")
return
if sys.argv[1] == "list":
# print all available android devices
res = subprocess.check_output([ADB_EXE, "devices"])
for line in res.splitlines():
print(line)
return
dev_name = sys.argv[1]
print(f"Selected device: {dev_name}")
if dev_name not in DEVICES:
print(f"Device is not in the list, skipping.")
return
dev_id, apk = DEVICES[dev_name]
# "-r" means force install
res = subprocess.check_output([ADB_EXE, "-s", dev_id, "install", "-r", apk])
for line in res.splitlines():
print(line)
print(f"-- Deployment into {dev_id} complete.")
if __name__ == "__main__":
run()
To list all devices:
python3 dp.py list
To deploy specific apk to specific device:
python3 dp.py YOUR_DEVICE_PSEUDO_NAME
