Detect update failures This allows to delete the update only if the installation succeeded and to notify the user in case the installation failed. Since we now need the file in case of failure, create a copy for uncrypt even if the user chose to delete installed updates. Change-Id: I80b0f499663bbf50bcbca5f643c01ffdb4cd3957
Simple application to download and apply OTA packages.
The app sends GET requests to the URL defined by the updater_server_url resource (or the lineage.updater.uri system property) and expects as response a JSON with the following structure:
{ "response": [ { "datetime": 1230764400, "filename": "ota-package.zip", "id": "5eb63bbbe01eeed093cb22bb8f5acdc3", "romtype": "nightly", "size": 314572800, "url": "https://example.com/ota-package.zip", "version": "15.1" } ] }
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.lineage.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.lineage.build.version property.
Additional attributes are ignored.
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:
gen-keystore.shmake UpdaterStudio from the root of the Android source tree. This command will add the needed libraries in system_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.
