It contains a +sample client for `update_engine` to install A/B (seamless) updates. + +A/B (seamless) update is available since Android Nougat (API 24), but this sample +targets the latest android. + + +## Workflow + +SystemUpdaterSample app shows list of available updates on the UI. User is allowed +to select an update and apply it to the device. App shows installation progress, +logs can be found in `adb logcat`. User can stop or reset an update. Resetting +the update requests update engine to cancel any ongoing update, and revert +if the update has been applied. Stopping does not revert the applied update. + + +## Update Config file + +In this sample updates are defined in JSON update config files. +The structure of a config file is defined in +`com.example.android.systemupdatersample.UpdateConfig`, example file is located +at `res/raw/sample.json`. + +In real-life update system the config files expected to be served from a server +to the app, but in this sample, the config files are stored on the device. +The directory can be found in logs or on the UI. In most cases it should be located at +`/data/user/0/com.example.android.systemupdatersample/files/configs/`. + +SystemUpdaterSample app downloads OTA package from `url`. In this sample app +`url` is expected to point to file system, e.g. `file:///data/my-sample-ota-builds-dir/ota-002.zip`. + +If `ab_install_type` is `NON_STREAMING` then app checks if `url` starts +with `file://` and passes `url` to the `update_engine`. + +If `ab_install_type` is `STREAMING`, app downloads only the entries in need, as +opposed to the entire package, to initiate a streaming update. The `payload.bin` +entry, which takes up the majority of the space in an OTA package, will be +streamed by `update_engine` directly. The ZIP entries in such a package need to be +saved uncompressed (`ZIP_STORED`), so that their data can be downloaded directly +with the offset and length. As `payload.bin` itself is already in compressed +format, the size penalty is marginal. + +if `ab_config.force_switch_slot` set true device will boot to the +updated partition on next reboot; otherwise button "Switch Slot" will +become active, and user can manually set updated partition as the active slot. + +Config files can be generated using `tools/gen_update_config.py`. +Running `./tools/gen_update_config.py --help` shows usage of the script. + + +## Sample App State vs UpdateEngine Status + +UpdateEngine provides status for different stages of update application +process. But it lacks of proper status codes when update fails. + +This creates two problems: + +1. If sample app is unbound from update_engine (MainActivity is paused, destroyed), + app doesn't receive onStatusUpdate and onPayloadApplicationCompleted notifications. + If app binds to update_engine after update is completed, + only onStatusUpdate is called, but status becomes IDLE in most cases. + And there is no way to know if update was successful or not. + +2. This sample app demostrates suspend/resume using update_engins's + `cancel` and `applyPayload` (which picks up from where it left). + When `cancel` is called, status is set to `IDLE`, which doesn't allow + tracking suspended state properly. + +To solve these problems sample app implements its own separate update +state - `UpdaterState`. To solve the first problem, sample app persists +`UpdaterState` on a device. When app is resumed, it checks if `UpdaterState` +matches the update_engine's status (as onStatusUpdate is guaranteed to be called). +If they doesn't match, sample app calls `applyPayload` again with the same +parameters, and handles update completion properly using `onPayloadApplicationCompleted` +callback. The second problem is solved by adding `PAUSED` updater state. + + +## Sample App UI + +### Text fields + +- `Current Build:` - shows current active build. +- `Updater state:` - SystemUpdaterSample app state. +- `Engine status:` - last reported update_engine status. +- `Engine error:` - last reported payload application error. + +### Buttons + +- `Reload` - reloads update configs from device storage. +- `View config` - shows selected update config. +- `Apply` - applies selected update config. +- `Stop` - cancel running update, calls `UpdateEngine#cancel`. +- `Reset` - reset update, calls `UpdateEngine#resetStatus`, can be called + only when update is not running. +- `Suspend` - suspend running update, uses `UpdateEngine#cancel`. +- `Resume` - resumes suspended update, uses `UpdateEngine#applyPayload`. +- `Switch Slot` - if `ab_config.force_switch_slot` config set true, + this button will be enabled after payload is applied, + to switch A/B slot on next reboot. + + +## Sending HTTP headers from UpdateEngine + +Sometimes OTA package server might require some HTTP headers to be present, +e.g. `Authorization` header to contain valid auth token. While performing +streaming update, `UpdateEngine` allows passing on certain HTTP headers; +as of writing this sample app, these headers are `Authorization` and `User-Agent`. + +`android.os.UpdateEngine#applyPayload` contains information on +which HTTP headers are supported. + + +## Used update_engine APIs + +### UpdateEngine#bind + +Binds given callbacks to update_engine.
