Using HBuild to package vue project APP, has been a failure.

it has been packed many times and has been reported wrong all the time. I packed the dist bag directly.
I have changed the index under config

according to reason, there is no problem. As a result, the APK packaged with Android has failed all the time.
the APK packaged with IOS can be successful. Ask
the error code for packing is as follows,

manifest.plus.distribute.splashscreen.android.mdpi;manifest.plus.distribute.splashscreen.android.ldpi;
