Common Problems

install failed due to grant request permissions failed

We need to change application permission level Solution: 1. Open the directory where the OpenHarmony SDK is located (you can view it by clicking Tools > SDK Manager > OpenHarmony SDK in the DevEco Studio menu bar).

1. Navigate to the Toolchains > {Version} > lib folder under the SDK directory, and open the UnsignedReleasedProfileTemplate.json file.

2. Change the parameter in bundle-info as following:

    "bundle-info":{
    ...
        "apl":"system_core",
        "app-feature":"hos_system_app"
    },

Note

If switching the system permissions does not work, try regenerating the automatic signature files.
