ok, weird, I just installed 9.01 Shield Experience, removed 1.04 and removed wolf launcher, reinstalled Wolf 1.1.9 and it worked. Also worked with FLauncher.
Can you try one last time with 1.04 and latest Wolf? download 104 (and make sure it installs, I usually install it on my phone first - without running and it and removing it right after, just to make sure the apk isn't corrupt, then transfer it to the shield using x-plore (don't use ES File explorer, unsafe). Streamhub's library from Unlink has latest wolf launcher and x-plore if you need it...
I tried the Streamhub but I kept getting a parsing error. Besides, I already have Wolf Launch 0.1.9 installed. So, I went online to several 3rd party sites and there is no v.1.1.9 I am figuring you did a typo. I believe the most current version of the Wolf Launcher is v.0.1.9
Ok, got it figured out and it probably always did work properly. After I disabled the Wolf Launcher, I would click on the back button on the v.1.0.3. With the new updated v.1.0.4 if you click the back button you stay on the Wolf Launcher, but when you click on the home button then it takes you back to the nvidia stock launcher home page. What is weird though, if I disable the Wolf Launcher and click the back button it takes me to the Wolf Launcher page. Now I can do everything on that page as normal i.e., clicking on apps, exiting those apps search, play, etc... and everything functions fine, but as soon as I click the home button it will take back to the nvidia home page.
It doesn't bother me, but I was wondering if that is harmful in any way? If not, then why not just enable the Wolf Launcher. Then immediately disable it and click the back button instead of the home button and surf around on the Wolf Launcher page and when you want to go back to the nvidia home page just click on the home button without going to the Launch Mager app since you have already disabled the Wolf Launcher. Does that make sense? Try it. After you have disabled the Wolf Launcher click the back button and it will stay on the Wolf page. Now while you are there click your home button and it will switch you to the nvidia home page without going back to the Launcher Manager to disable the Wolf page, because it has already been disabled.
Btw, I was just used to clicking the back button to go to either navidia's or Wolf screens with the v.1.0.3. The v1.0.4 requires you to click the home button instead. When I enable Wolf, I can click the return button and it takes me to the Wolf page, but when I disable the Wolf page, I have to click the home button to go back to the nvidia page. Clicking the return button does not take you back to nvidia page.
Btw, what is the point of the new option "Custom Launcher Options"? Why would I want to launch by default to any app other than the Wolf Launcher? I can map a button on my remote to do that. Right now, I have 48 apps hidden on my Wolf page and with 1 click on my mouse they are revealed for me to use. Then with another click they will all disappear again. I have my Tivimate app embedded on my background pic and with a click on my Go/Select button on my remote it will launch my Tivimate app. So, I don't understand why I would use the Custom Launcher Option? Am I missing something, or not understanding the function?
