What is, "performing streamed install"

Question

I am running a build through adb command,

adb install myapp.apk

In the console, I get the message, Performing streamed install

What does this mean.

Answer 1

PackageManager has 2 CLI interfaces - legacy pm and new cmd package.

The legacy installation process required uploading the .apk file to /data/local/tmp folder first. The new process has the (default) option of using pipelines instead of the temporary file. This option is called Streamed Install.

Answer 2

It seems to be the previously installed application and caused the cache to be unable to continue. I have tried many ways and the simplest way to fix it is to restart your phone or virtual machine
