Project due to a change of engine(UE4 .16-> UE4 .17), now packaged on the mobile phone, there is a problem with the widget logic, object instance destruction timing change. But on the PC, the program runs normally, and only after packing to the phone will there be problems with widget, incomplete level removal, and repeated loading. Here you can see http://zompi.pl/unreal-engine-4-debuging-on-android / debugging your phone through native code via Nsight Tegra in Nvidia, which may have failed to do so due to engine version differences or updates to debugging mechanisms. Here I want to find a master who understands the Nsight Tegra debugging mobile phone to solve the puzzle, if any answer, thank you! !
