The Gunners were not able to get the win, as they could only find an equalizer to cancel out Farid El Melali's 13th minute opener.
Reiss Nelson got Arsenal back level, but they were not able to find the winning goal for the rest of the game.
However, Emery was pleased with everyone who played as they work on their fitness ahead of the new season.
He said to the club's official website after the friendly: "Good evening. We are going to play the first match away against Newcastle, and tonight was a similar performance against that sort of opposition Angers, and also they were giving everything in their performance against us for their supporters.
"There were two very different halves. The first half they started harder than us and they scored. We didn't control the game like we wanted.
"In the second half we became better to control the game, with the ball and having more chances to score. I think from the second half we deserved a better result. But the most important thing today was to work well physically and with different players.
"Also today the young players took some minutes, knowing we needed a performance against a difficult team here away. Little by little we are closer to starting the first game against Newcastle.
"We are working and preparing the team with different players and above all we are going to progress, finding our first idea with the players, and above all every player can be ready to player and be ready for the season."
