[Solved] adb install successfully but can't open the app on Huawei phone

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.
