1+! intent-service-foreground
2+
3+IntentService を使って非同期処理を実現するサンプル．
4+
5+バックグラウンドサービスはOreo(API Level 26)以降は基本的に許可されず強制終了されてしまう。
6+そのため非同期タスクを投げる場合には通知を表示してフォアグラウンドサービスとする必要がある。
7+
8+IntentService を使ってフォアグラウンドサービスを実現するサンプル。
9+
10+* Service#startForeground() - API Level 5
11+
12+
13+以下参考サイト
14+* http://techbooster.jpn.org/andriod/application/1570/
15+
16+以下まとめ。
17+* タスクは startService() で呼び出すたびにキューイングされる
18+* IntentService で同時に作業できるタスクは１つ
19+* キューにタスクが一つもなくなったらサービスは自動で終了する
20+* バックグラウンドで動作し続けるというよりはバッチ処理的なものに使う
21+
22+
23+!! ビルドターゲット
24+
25+http://maven-android-plugin-m2site.googlecode.com/svn/plugin-info.html
26+
27+* mvn compile - アプリケーションのコンパイル
28+* mvn package - apk の作成
29+* mvn clean - ビルドファイルの削除
30+* mvn install - maven の local リポジトリにインストール
31+
32+* mvn android:deploy - エミュレータやデバイスにインストール
33+* mvn android:generate-sources
34+
35+* mvn install - アプリケーションのインストール
36+* mvn uninstall - アプリケーションのアンインストール
