-&nbsp;In&nbsp;My&nbsp;Test&nbsp;Result
&nbsp;&nbsp;&nbsp;&nbsp;Android&nbsp;6.0&nbsp;can't&nbsp;loading&nbsp;so&nbsp;file&nbsp;when&nbsp;so&nbsp;file&nbsp;has&nbsp;text&nbsp;relocations&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;(&nbsp;Dynamic&nbsp;section&nbsp;at&nbsp;offset&nbsp;0x42f424&nbsp;contains&nbsp;32&nbsp;entries:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Tag&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Type&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Name/Value

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;....&nbsp;)

I&nbsp;want&nbsp;to&nbsp;believe&nbsp;that&nbsp;my&nbsp;testing&nbsp;result&nbsp;is&nbsp;wrong,&nbsp;but&nbsp;If&nbsp;android&nbsp;app's&nbsp;policy&nbsp;will&nbsp;be&nbsp;changed,
It's&nbsp;big&nbsp;problem.&nbsp;or&nbsp;just&nbsp;My&nbsp;mistake&nbsp;?

Can&nbsp;I&nbsp;fix&nbsp;the&nbsp;problem&nbsp;in&nbsp;manual&nbsp;(or&nbsp;fix&nbsp;with&nbsp;tricky&nbsp;method&nbsp;for&nbsp;temporary&nbsp;?)


Best&nbsp;Regards
