ここんところ、WebRTCのアプリを作ろうとして、四苦八苦していました。
やっと、データチャンネルで送受信するアプリができたので、ここに公開します。
開発環境ですが
Android Studio 1.2.1.1 build 141.19032520
を使って開発しています。
普通にプロジェクトを作成します。
まず、WebRTCのライブラリをインポートする為の設定を行います。
app配下にあるbuild.gradleのdependenciesに下記の一行を入れるだけ
compile 'io.pristine:libjingle:9357@aar'
これでなんと、ネイティブのsoライブラリまで持ってきてくれます（なんと便利な！）
次に、AndroidManifest.xmlにパーミッションを追加します
<uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <uses-feature android:glEsVersion="0x00020000" android:required="true" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
これで、準備OK、ここからは、MainActivity.javaのソースをそのまま掲載しちゃいます。
