Successful workaround: Kill the ADB process if it does not return within 120 seconds.
al...@google.com
I've seen the same problem on rare occasion -- I believe on both 32-bit and 64-bit machines (all running Ubuntu).
This scenario is from an Amazon EC2 instance running Ubuntu 10.04.
== Long-running processes involved:
* PID 4440 adb (daemon)
* PID 5396 adb -s localhost:52384 install -r MyApp-debug.apk
* PID 5216 emulator -ports 38007,52384 -no-boot-anim -prop persist.sys.language=de -prop persist.sys.country=DE -avd hudson_de-DE_240_WVGA_android-8 -no-window
== Commands run:
* adb daemon was (presumably) already running
* emulator is started as above
* `adb connect localhost:52384`
* `adb logcat -v time` is left running in the background
* `adb install` below is run once emulator is ready
adb -s localhost:52384 install -r MyApp-debug.apk
116 KB/s (57642 bytes in 0.482s)
pkg: /data/local/tmp/MyApp-debug.apk
Success
** hangs here indefinitely without returning (despite "Success") **
== Investigation
* `ps` shows that the hung `adb install` process has PID 5396
root@ip-10-228-211-159:~# strace -p 5396
Process 5396 attached - interrupt to quit
read(4, ^C <unfinished ...>
Process 5396 detached
* adb is blocked reading from FD 4 -- what is that?

I experienced the same problem several times. This is kind of a blocker for me as my regression test system uses adb commands repeatedly.
Experienced hang for "install","uninstall","shell" commands.

I had this problem too until I restarted the usb daemon using the command "adb usb" and it works
ap...@google.com
The point here is we shouldn't HAVE to restart the daemon.
ap...@google.com
There is a case where issuing "adb usb" does not reestablish the device in the device list produced via "adb devices". The device can be resuscitated by disabling "USB debugging" and then enabling it again using the Settings -> Applications -> Development settings menu.
ap...@google.com
WORKAROUND: Calling adb_proxy.py in place of adb directly will greatly improve reliability.

I am seeing a similar issue collecting logcat logs. In my case I am connecting to on the order of 30 devices over TCP with logcat, in which I occasionally have to disconnect and reconnect devices. Eventually (between 1 and 12 hours) the adb server just completely stops responding to commands. I have to send SIGKILL to the server process to kill it so I can restart it. I grabbed a stack trace from one hung adb server process:

Request Google to provide a work around for the same, as this is a blocker for CTS and monkey testing.

I experienced the same issue. Manual workaround is not suitable, since I would like to automate unit tests after each build at Jenkins.
ap...@google.com
salwin...@gmail.com, have you tried the Android Emulator Plugin for Jenkins: https://wiki.jenkins-ci.org/display/JENKINS/Android+Emulator+Plugin
It runs a separate adb server for each Jenkins job, and kills it after running the session. That should significantly reduce the number of hangs you experience - and the impact of those hangs.

Did anyone ever root cause this? I am in the same boat with an android V6 device (HTC touch), and it's really causing some problems. Doesn't seem to happen with the same script on a V7 device though.
ap...@google.com
I dug into it for a while about a year ago and started to improve the debug logging in adb, but ran out of free time and never ended up getting far enough along to find the problem. I'll see if I still have the code however; if I do I'll put it up on github so that it can be continued.
ap...@google.com
We are also experiencing this issue during our automated tests ON A DAILY BASIS.
We are using an emulator though, and not a real device as some have described, although i am not sure it really matters.
Is there anyone who knows what is the root cause or how this can be fixed? (or at least improve the stability) ?

Finally find this thread! I am experiencing same issue. adb devices work. But adb install, adb shell all hangs. I am using Ubuntu via VM Player. The issue happened after I update VM player. I tried to reinstall adb, tried to copy other's ubuntu. None of them brings my adb working correctly. I have to reinstall vmplayer, ubuntu, adb and everything eventually. Any thoughts, Googler and Google Android team??

Just flag clean-up work remaining.
Description
We'd like to combine
current.txtandpublic_plus_experimental.txt, but we don't want to check compatibility for the APIs meta-annotated with@RequiresOptIn.Our handling of APIs looks like this:
@RequiresOptIn@RestrictTo(LIBRARY)@RestrictTo(LIBRARY_GROUP)@RestrictTo(LIBRARY_GROUP_PREFIX)And the easiest way to implement Reviewed is to use separate files, which means we'll want to differentiate
@RequiresOptIn.Tentatively, I'd like to pass a list of annotations (and meta-annotations) to Metalava. APIs with these annotations should not raise errors during compatibility checking. The annotations should not propagate to subclasses.
