At present, an error message is displayed when the android APK is installed.

Install success as usual.
The above four error messages happen occasionally after I use ADB install-r xxx.apk, but I still don't know the detailed reasons,
I am a paranoid, so I must study why it is...
Thanks to Google, I found that a bunch of people asked the same question, but they all gave the answer to the simulated hacker. Some people say that
Some people say that the original APK is still running when installing AVD and simulator versions .....
None! There are a lot of dishes on the Internet.
This is slightly different, but yes it is benign.
When installing/launching app, the tools use Java based tools on
Device to perform these operation (shell command 'am' and 'pm' which
Stand for activitymanager and packagemanager ).
Because these apps run in VM, they show up on ddms which then tries
Connect to them like any other apps. But because those apps are very
Short lived they usually don't answer to some request, which ends up
With a timeout and these error messages.
This output is so benign in fact that we removed it from newer version
Of the VM.
