This is not the same problem as #834. Please post the following:

• The relevant parts of your code
• Which device and Android version the problem happens on
• Which device and Android version the problem doesn't happen on (if any)

[mhsmith]

If this is still a problem, please post the requested information, and I'll reopen the issue.

sry, i just saw the message, i already solve the problem. the reason is that i used the armv7a. it works when i config in armv8 it works.

by the way, i used the brief tutorial U provided at #527 (comment), it works.
