Android OS 7 以上で Charles を使う

Last updated at Posted at 2019-04-04

はじめに

社内のAndroid端末で Charles を使ったときのメモ。
Android OS 7 以上では、 SSL通信(https)を割り込むのに、以下の設定が必要だった。

Charlesについては割愛。

環境

Android OS 8.0.0
macOS High Sierra 10.13.6

証明書の書き出し

Help -> SSL Proxying -> Save Charles Root Certificate...

適当に certificate.pem で保存。

アプリの設定

  1. 書き出したファイルを追加

    rawフォルダが無ければ作成する。

/app/src/main/res/raw/certificate.pem



2. 設定ファイルを作成。

    格納場所は `/app/src/main/res/xml` 配下。
    ファイル名は適当に `network_security_config.xml` とする。

    ```xml:/app/src/main/res/xml/network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config>
        <trust-anchors>
            <certificates src="system"/>
        </trust-anchors>
    </base-config>
    <debug-overrides>
        <trust-anchors>
            <certificates src="@raw/certificate"/> ← さっき作成したファイル
        </trust-anchors>
    </debug-overrides>
</network-security-config>
  1. AndroidManifest.xmlに1行追加

    AndroidManifest.xml
    <application
        android:networkSecurityConfig="@xml/network_security_config"   追加
    

以上。
