From f4d280ce40ba0aa50d6b2c70d8031ddf7678d179 Mon Sep 17 00:00:00 2001 From: Zhomart Mukhamejanov Date: Tue, 17 Apr 2018 13:20:22 -0700 Subject: sample_updater: add non-streaming demo SampleUpdater app was tested manually on a device. There are unit tests for utility classes. SampleUpdater app demonstrates how to use Android Update Engine to apply A/B (seamless) update. This CL contains demo of non-stream update using async update_engine, which is accessed directly from an activity. This app also shows logs from update_engine on the UI. Instructions can be found in `README.md`. - Create a UI with list of configs, current version, control buttons and a progress bar - Add PayloadSpec and PayloadSpecs for working with update zip file - Add UpdateConfig for working with json config files - Add applying non-streaming update Test: tested manually and unit tests for utilities Change-Id: I05d4a46ad9cf8b334c9c60c7dd4da486dac0400a Signed-off-by: Zhomart Mukhamejanov --- .../util/UpdateEngineErrorCodes.java | 84 ++++++++++++++++++++++ 1 file changed, 84 insertions(+) create mode 100644 sample_updater/src/com/example/android/systemupdatersample/util/UpdateEngineErrorCodes.java (limited to 'sample_updater/src/com/example/android/systemupdatersample/util/UpdateEngineErrorCodes.java') diff --git a/sample_updater/src/com/example/android/systemupdatersample/util/UpdateEngineErrorCodes.java b/sample_updater/src/com/example/android/systemupdatersample/util/UpdateEngineErrorCodes.java new file mode 100644 index 000000000..e63da6298 --- /dev/null +++ b/sample_updater/src/com/example/android/systemupdatersample/util/UpdateEngineErrorCodes.java @@ -0,0 +1,84 @@ +/* + * Copyright (C) 2018 The Android Open Source Project + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +package com.example.android.systemupdatersample.util; + +import android.os.UpdateEngine; +import android.util.SparseArray; + +import java.util.Arrays; +import java.util.HashSet; +import java.util.Set; + +/** + * Helper class to work with update_engine's error codes. + * Many error codes are defined in {@link UpdateEngine.ErrorCodeConstants}, + * but you can find more in system/update_engine/common/error_code.h. + */ +public final class UpdateEngineErrorCodes { + + /** + * Error code from the update engine.
