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 --- .../updates/AbNonStreamingUpdate.java | 52 ++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 sample_updater/src/com/example/android/systemupdatersample/updates/AbNonStreamingUpdate.java (limited to 'sample_updater/src/com/example/android/systemupdatersample/updates/AbNonStreamingUpdate.java') diff --git a/sample_updater/src/com/example/android/systemupdatersample/updates/AbNonStreamingUpdate.java b/sample_updater/src/com/example/android/systemupdatersample/updates/AbNonStreamingUpdate.java new file mode 100644 index 000000000..1b91a1ac3 --- /dev/null +++ b/sample_updater/src/com/example/android/systemupdatersample/updates/AbNonStreamingUpdate.java @@ -0,0 +1,52 @@ +/* + * 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.updates; + +import android.os.UpdateEngine; + +import com.example.android.systemupdatersample.PayloadSpec; +import com.example.android.systemupdatersample.UpdateConfig; +import com.example.android.systemupdatersample.util.PayloadSpecs; + +/** + * Applies A/B (seamless) non-streaming update. + */ +public class AbNonStreamingUpdate { + + private final UpdateEngine mUpdateEngine; + private final UpdateConfig mUpdateConfig; + + public AbNonStreamingUpdate(UpdateEngine updateEngine, UpdateConfig config) { + this.mUpdateEngine = updateEngine; + this.mUpdateConfig = config; + } + + /** + * Start applying the update.
