PawletOS Updater
OTA update app for PawletOS. Forked from the LineageOS Updater.
Downloads and applies A/B (seamless) OTA packages via update_engine.
Server requirements
The app sends GET requests to the URL defined by the updater_server_url
resource (or the pawlet.updater.uri system property) and expects as response
a JSON with the following structure:
{
"response": [
{
"datetime": 1230764400,
"filename": "ota-package.zip",
"id": "5eb63bbbe01eeed093cb22bb8f5acdc3",
"romtype": "release",
"size": 314572800,
"url": "https://updates.pawlet.me/builds/rpi4/ota-package.zip",
"version": "1.0"
}
]
}
The datetime attribute is the build date expressed as UNIX timestamp.
The filename attribute is the name of the file to be downloaded.
The id attribute is a string that uniquely identifies the update.
The romtype attribute is the string to be compared with the ro.pawlet.releasetype property.
The size attribute is the size of the update expressed in bytes.
The url attribute is the URL of the file to be downloaded.
The version attribute is the string to be compared with the ro.pawlet.build.version property.
Additional attributes are ignored.
The default server URL template is https://updates.pawlet.me/api/v1/{device}/
where {device} is replaced at runtime with ro.product.device.
Build with Android Studio
Updater needs access to the system API, therefore it can't be built only using the public SDK. You first need to generate the libraries with all the needed classes. The application also needs elevated privileges, so you need to sign it with the right key to update the one in the system partition. To do this:
- Place this directory anywhere in the Android source tree
- Generate a keystore and keystore.properties using
gen-keystore.sh - Build the dependencies running
make UpdaterStudiofrom the root of the Android source tree. This command will add the needed libraries insystem_libraries/.
You need to do the above once, unless Android Studio can't find some symbol.
In this case, rebuild the system libraries with make UpdaterStudio.
