Can we leave it out? adb push out/arm64/dm /data/local/tmp adb shell "cd /data/local/tmp; ./dm --src gm --config gpu" Seeing those two steps laid out I think it should be obvious that you are responsible to put files where the program can find them. And if anybody does forget to push the resources because they are following those steps, dm will complain and remind them to do so. mtklein_C 2016/09/16 19:30:56 I see your point but every app we have to use as a Show quoted text On 2016/09/16 at 19:25:09, csmartdalton wrote: > Resources are specific to the dm binary itself as opposed to gn.

And if anybody does forget to push the resources because they are following those steps, dm will complain and remind them to do so. I see your point but every app we have to use as an example (dm, nanobench) needs resources. I'd rather not write instructions that fail.
