+# bootable/recovery project uses repohook to apply `clang-format` to the changed lines, with the
+# local style file in `.clang-format`. This will be triggered automatically with `repo upload`.
+# Alternatively, one can stage and format a change with `git clang-format` directly.
+#
+# $ git add <files>
+# $ git clang-format --style file
+#
+# Or to format a committed change.
+#
+# $ git clang-format --style file HEAD~1

+# `$ANDROID_BUILD_TOP/prebuilts/clang/host/linux-x86/clang-stable/bin/clang-format`), which might
+# give slightly different results from the one installed in host machine (e.g.

+Recovery Image Generator
+-------------------------
+
+This program uses java.awt.Graphics2D to generate the background text files used
+under recovery mode. And thus we don't need to do the manual work by running
+emulators with different dpi.
+
+# Usage:
+ `java -jar path_to_jar --image_width imageWidth --text_name textName --font_dir fontDirectory
+ --resource_dir resourceDirectory --output_file outputFilename`
+
+# Description of the parameters:
+1. `imageWidth`: The number of pixels per line; and the text strings will be
+ wrapped accordingly.
+2. `textName`: The description of the text string, e.g. "recovery_erasing",
+ "recovery_installing_security"
+3. `fontDirectory`: The directory that contains all the support .ttf | .ttc
+ files, e.g. $OUT/system/fonts/
+4. `resourceDirectory`: The resource directory that contains all the translated
+ strings in xml format, e.g. bootable/recovery/tools/recovery_l10n/res/
+5. `outputFilename`: Path to the generated image.

+# SystemUpdaterSample
+
+This app demonstrates how to use Android system updates APIs to install
+[OTA updates](https://source.android.com/devices/tech/ota/). 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. When update_engine successfully
+initialized, it's guaranteed to invoke callback onStatusUpdate.
+
+### UpdateEngine#applyPayload
+
+Start an update attempt to download an apply the provided `payload_url` if
+no other update is running. The extra `key_value_pair_headers` will be
+included when fetching the payload.
+
+`key_value_pair_headers` argument also accepts properties other than HTTP Headers.
+List of allowed properties can be found in `system/update_engine/common/constants.cc`.
+
+### UpdateEngine#cancel
+
+Cancel the ongoing update. The update could be running or suspended, but it
+can't be canceled after it was done.
+
+### UpdateEngine#resetStatus
+
+Reset the already applied update back to an idle state. This method can
+only be called when no update attempt is going on, and it will reset the
+status back to idle, deleting the currently applied update if any.
+
+### Callback: onStatusUpdate
+
+Called whenever the value of `status` or `progress` changes. For
+`progress` values changes, this method will be called only if it changes significantly.
+At this time of writing this doc, delta for `progress` is `0.005`.
+
+`onStatusUpdate` is always called when app binds to update_engine,
+except when update_engine fails to initialize.
+
+### Callback: onPayloadApplicationComplete
+
+Called whenever an update attempt is completed or failed.
+
+
+## Running on a device
+
+The commands are expected to be run from `$ANDROID_BUILD_TOP` and for demo
+purpose only.
+
+### Without the privileged system permissions
+
+1. Compile the app `mmma -j bootable/recovery/updater_sample`.
+2. Install the app to the device using `adb install <APK_PATH>`.
+3. Change permissions on `/data/ota_package/` to `0777` on the device.
+4. Set SELinux mode to permissive. See instructions below.
+5. Add update config files; look above at [Update Config file](#Update-Config-file).
+6. Push OTA packages to the device.
+7. Run the sample app.
+
+### With the privileged system permissions
+
+To run sample app as a privileged system app, it needs to be installed in `/system/priv-app/`.
+This directory is expected to be read-only, unless explicitly remounted.
+
+The recommended way to run the app is to build and install it as a
+privileged system app, so it's granted the required permissions to access
+`update_engine` service as well as OTA package files. Detailed steps are as follows:
+
+1. [Prepare to build](https://source.android.com/setup/build/building)
+2. Add the module (SystemUpdaterSample) to the `PRODUCT_PACKAGES` list for the
+ lunch target.
+ e.g. add a line containing `PRODUCT_PACKAGES += SystemUpdaterSample`
+ to `device/google/marlin/device-common.mk`.
+3. [Whitelist the sample app](https://source.android.com/devices/tech/config/perms-whitelist)
+ * Add
+ ```
+ <privapp-permissions package="com.example.android.systemupdatersample">
+ <permission name="android.permission.ACCESS_CACHE_FILESYSTEM"/>
+ </privapp-permissions>
+ ```
+ to `frameworks/base/data/etc/privapp-permissions-platform.xml`
+5. Build sample app `make -j SystemUpdaterSample`.
+6. Build Android `make -j`
+7. [Flash the device](https://source.android.com/setup/build/running)
+8. Add update config files; look above at `## Update Config file`;
+ `adb root` might be required.
+9. Push OTA packages to the device if there is no server to stream packages from;
+ changing of SELinux labels of OTA packages directory might be required
+ `chcon -R u:object_r:ota_package_file:s0 /data/my-sample-ota-builds-dir`
+10. Run the sample app.
+
+

+
+## Running tests
+
+The commands are expected to be run from `$ANDROID_BUILD_TOP`.
+
+1. Build `make -j SystemUpdaterSample` and `make -j SystemUpdaterSampleTests`.
+2. Install app
+ `adb install $OUT/system/priv-app/SystemUpdaterSample/SystemUpdaterSample.apk`
+3. Install tests
+ `adb install $OUT/testcases/SystemUpdaterSampleTests/SystemUpdaterSampleTests.apk`
+4. Run tests
+ `adb shell am instrument -w com.example.android.systemupdatersample.tests/android.support.test.runner.AndroidJUnitRunner`
+5. Run a test file
+ ```
+ adb shell am instrument \
+ -w -e class com.example.android.systemupdatersample.UpdateManagerTest#applyUpdate_appliesPayloadToUpdateEngine \
+ com.example.android.systemupdatersample.tests/android.support.test.runner.AndroidJUnitRunner
+ ```
+
+
+## Accessing `android.os.UpdateEngine` API
+
+`android.os.UpdateEngine` APIs are marked as `@SystemApi`, meaning only system
+apps can access them.
+
+
+## Getting read/write access to `/data/ota_package/`
+
+Access to cache filesystem is granted only to system apps.
+
+
+## Setting SELinux mode to permissive (0)
+
+```txt
+local$ adb root
+local$ adb shell
+android# setenforce 0
+android# getenforce
+```
