Issue
You installed the apk successfully to your huawei phone via
adb install
:
adb install xxx.apk
Performing Streamed Install
Success
But after the installation you can't open it as the open button is disabled, nor can you find or search it in your phone.
Analyse
There is a private space feature in huawei phone, and you turned it on.
Solution
Go to settings/privacy, you'll see the private space. Switch into that space and you can find the app.
Or you can delete the private space totally to avoid this issue in the future.
