We are experiencing extremely long installation/start/run times for Android Things applications on the NXP PICO-PI-IMX6UL. This issue is observable when using both Android Studio and adb directly on the command line.

A small application of ~2MB in size takes anywhere from 5 to 15 minutes to install. The same application on the Intel Edison only takes only a few seconds to install.

It's worth noting that other adb operations seem to run very slowly as well (i.e. shell, logcat, etc.).

We have closely followed the procedures outlined using these resources to install the Android Things image: https://developer.android.com/things/hardware/imx6ul.html

We have re-flashed the Android Things image several times and experience the same issues.

To rule out any application issues, we have tried installing/running the Android Things sample template application found here: https://github.com/androidthings/new-project-template and experience the same issues. We can verify that this application installs/runs without issue on an Intel Edison board running Android Things 4.1.

Here are a few more details about our setup:

Host:

• Mac OS 10.12.6
• Android Studio version 2.3.3
• Android Debug Bridge version 1.0.39

i.MX6UL:

• Android Things Developer Preview Image 5.1

Any suggestions on what is wrong with our setup or what might be causing these issues?

Thanks!

Update 10/20/2017

Further testing with additional NXP i.MX6UL boards has only shown minor improvements in installation and runtimes, and the results are not consistent. We also tried swapping out the daughterboard for an older version (Wandboard i.MX6UL), but the results were the same.

We plan to continue testing as newer versions of Android Things are released, but in the meantime we are going to continue development with the Intel Edison, despite it being discontinued.
