scanning the ble of ibeacon, Glide+okhttp3 load image very slow from server.

When the application starts, I first open the intentservice to download the audio, then opened the service to scan the Bluetooth equipment ibeacon. At this point, I found the picture from the server to download very slowly, in the local load is not affected.

I think the child thread may be blocked, how to solve it.

android os: huawei 6.0 and xiaomi 5.0
