私のAndroidテストアプリケーションでは、その後、Gmail APIで設定したGoogle Developer ConsoleからJSONファイルを取得し、それをエミュレーターに配置すると、次のようなIOExceptionが発生します。
"com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden { "code": 403, "errors": [ { "domain": "usageLimits", "message": "Access Not Configured. Google Developers Console を使用してプロジェクトの API を有効にしてください。", "reason" : "accessNotConfigured" } ], "message" : "アクセスが構成されていません。プロジェクトの API を有効にするには、Google Developers Console を使用してください。" }"
GoogleClientSecrets オブジェクトを使用する必要があると思いますが、その用途が見つかりません。
ここにコード：
public class MainActivity extends Activity
{
final String SCOPE = "oauth2:https://www.googleapis.com/auth/gmail.compose";
final String FILE_NAME = "TestEmail5.json";
private static final int REQUEST_RESOLVE_ERROR = 1001;
Button button;
OnClickListener sendListener = new OnClickListener()
{
@Override
public void onClick(View v)
{
new sendEmailTask().execute();
}
};
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button)findViewById(R.id.button1);
button.setOnClickListener(sendListener);
}

}

System.out.println(message.toPrettyString());
}

{
