ネットワーク トレースでは、Google Mobile Ads SDK に関連するネットワーク アクティビティを確認できます。これは、Google モバイル広告の実装をデバッグする際に役立ちます。
ネットワーク トレースを Charles プロキシなどのツールの代わりに使用する主なメリットとして、Android のすべてのバージョンと、Google Play 開発者サービスでサポートされているバージョンを搭載したデバイスで動作することが挙げられます。Android 7.0 以降に適用される CA 証明書の変更により、プロキシツールは対象外となります。

This can be useful in debugging your Google Mobile Ads implementation.\n\nA key reason to use network tracing instead of tools such as [Charles\nProxy](//www.charlesproxy.com) is that it works with **all** versions of\nAndroid and devices running a supported version of Google play services. This\nisn't the case with proxying tools due to changes in\n[trusted CAs and certificates in place since Android 7.0](//developer.android.com/about/versions/nougat/android-7.0#default_trusted_ca).\n\nThis guide explains how to enable network tracing for debugging purposes.\n\nEnable tracing\n\nTo enable network tracing, [enable developer\noptions](//developer.android.com/studio/debug/dev-options) for your device.\nThen, launch the **Google Settings** app and select the **Ads** option:\n\nAssuming you have developer options enabled and the feature is available, your\nscreen would then look like this:\n\nSelect the **Enable debug logging for ads** option to bring up following dialog:\n\nTap **OK** and you're then presented with an advertising identifier that ends\nwith `10ca1ad1abe1`:\n\nYou are now able to see all the output from the network logging in logcat. To\nfilter only Information-level Ads output to both the screen and a file, issue\nthe following command: \n\n adb logcat '*:S' Ads:I Ads-cont:I | tee logs.txt\n\nOutput\n\nStandard platform-appropriate console logs are used to output the network logs.\n\nConsole log messages always begin with the string `GMA Debug BEGIN`,\n`GMA Debug CONTENT`, or `GMA Debug FINISH`, so you can search or filter on these\nstrings. For each network log, the first log message is `GMA Debug BEGIN`,\nthe last log message is `GMA Debug FINISH`, and the network log content begins\nwith `GMA Debug CONTENT`. If content is too long to fit on a line, it is split\namong multiple lines, each line beginning with `GMA Debug CONTENT`.\n\nConsole output example \n\n I/Ads ( 4660): GMA Debug BEGIN\n I/Ads ( 4660): GMA Debug CONTENT {\"timestamp\":1510679993741,...}\n I/Ads ( 4660): GMA Debug FINISH\n\nJSON output example\n\nHere are some samples of JSON output from logcat:\n\nonNetworkRequest \n\n {\n \"timestamp\": 1510679994904,\n \"event\": \"onNetworkRequest\",\n \"components\": [\n \"ad_request_cf5ab185-3c3f-4f01-9f56-33da2ae110f2\",\n \"network_request_6553bc32-1d44-4f18-9dd0-5c183abbeb90\"\n ],\n \"params\": {\n \"firstline\": {\n \"uri\": \"http://googleads.g.doubleclick.net/pagead/ads?carrier=....\",\n \"verb\": \"GET\"\n },\n \"headers\": [\n {\n \"name\": \"User-Agent\",\n \"value\": \"Mozilla/5.0 (Linux; Android 5.0.2;...\"\n }\n ]\n }\n }\n\nonNetworkResponse \n\n {\n \"timestamp\": 1510679995295,\n \"event\": \"onNetworkResponse\",\n \"components\": [\n \"ad_request_cf5ab185-3c3f-4f01-9f56-33da2ae110f2\",\n \"network_request_6553bc32-1d44-4f18-9dd0-5c183abbeb90\"\n ],\n \"params\": {\n \"firstline\": {\n \"code\": 200\n },\n \"headers\": [\n {\n \"name\": null,\n \"value\": \"HTTP/1.1 200 OK\"\n },\n {\n \"name\": \"X-Google-DOS-Service-Trace\",\n \"value\": \"main:pagead\"\n },\n {\n \"name\": \"Content-Type\",\n \"value\": \"text/html; charset=UTF-8\"\n },\n ...\n ]\n }\n }\n\nonNetworkResponseBody \n\n {\n \"timestamp\": 1510679995375,\n \"event\": \"onNetworkResponseBody\",\n \"components\": [\n \"ad_request_cf5ab185-3c3f-4f01-9f56-33da2ae110f2\",\n \"network_request_6553bc32-1d44-4f18-9dd0-5c183abbeb90\"\n ],\n \"params\": {\n \"bodydigest\": \"B2520049D02F3C70A12AD1BC0D1B58A4\",\n \"bodylength\": 122395\n }\n }"]]
