Successful workaround: Kill the ADB process if it does not return within 120 seconds.
wu...@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 had this problem too until I restarted the usb daemon using the command "adb usb" and it works
ta...@google.com
The point here is we shouldn't HAVE to restart the daemon.
ki...@gmail.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.

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:

wu...@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.

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.

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.

Any thoughts, Googler and Google Android team??

I gave this a try on a Samsung and don't see the darkening like I do on Pixel, so this really does look like a HAL issue.
On Pixel, comparing the capture result keys between the auto and manual exposure sessions that have primitive values (such as exposure time / post raw sensitivity boost), there's no apparent difference.
HAL team - can you try out the repro app provided in
m....@gmail.com
In my case, I tried it on: Pixel6, Samsung Note10+ and Samsung S23U, all do the same unfortunately. But at least we agree on the fact that if it is happening on all phones, then it is not HAL issue right? and if it is happening on say Pixels only, then it is OEM issue, right?

What fixes this issue on Ubuntu 14.04 is disabling of MTP in Settings > Storage > Hamburger icon (top-right) > USB computer connection (Nexus). I guess what happens is that Ubuntu runs some service that tries to mount nexus as MTP device and that interacts with ADB in a bad way (makes it crash).

I was having a similar issue with Eclipse -- it was getting locked up by the adb thread.
In Linux only (two very different distos -- Fedora and Ununtu), but not in Windows 8.1.
Tried some magic things in udev, replaced cables, no help... What finally fixed it was tweaking some USB settings in the BIOS.
This is my original bug report:https://code.google.com/p/android/issues/detail?id=75562
FWIW, YMMV, etc...

I encountered this problem when running an emulator image built from the Android source code. I only had this problem when I create the x86 image, the ARM image works just fine.
I found a solution.
I discovered that if I send any command to the adb shell while it is hanging, it will resume its task. To solve my problem I just run the following bash script in parallel while I'm running my regression tests:
#!/bin/bash
while [ true ]
do
adb shell exit
sleep 60
done

any results on this issue?

We have improved our testing to catch this issue moving forward.
ga...@google.com
Is there any API definition that requires manual exposure final output(yuv) matches auto exposure?
bo...@google.com
Particularly: "If the camera device cannot apply the exact boost requested, it will reduce the boost to the nearest supported value. The final boost value used will be available in the output capture result."
CONTROL_POST_RAW_SENSITIVITY_BOOST is meant to control any additional brightening / darkening after hardware gain. If the CaptureResult, when AE is on, is reporting a value that when applied to a manual capture request results in a differently-brightened image, then the value isn't accurate (which is the case for Pixel).
So really, there's two ways to deal with this - either the brightness needs to match for both AE and manual given these keys, or the value for CONTROL_POST_RAW_SENSITIVITY_BOOST reported by AE needs to change. From a quality standpoint, though, an app should be able to switch between AE and manual and not receive a radically different result.
rm...@google.com
The current exposure algorithm and overall camera system may not be setup to match manual mode to fully automatic mode. If this becomes a requirements, the tuning and testing effort will widen substantially to cover all possible combinations.
Manual mode uses a simpler flow that eliminates most advanced features.

Description
We are building an application that allows the users to manage the camera2 manually like a pro. One of the features is to set the iso and shutter speed manually and automatically based on the user choice, when the user selects manual exposure the values of the iso and shutterspeed are set to the last value reported in the "result: TotalCaptureResult" variable in the setSessionCaptureCallback, the issue is that the image is completely different. So the auto exp says for example ISO=X and ShutterSpeed=Y, then user selects manual mode, we make it manual and before the user sets anything we set the initial values of ISO to be X and ShutterSpeed to be Y but the image is much darker. All what I can think of is that this is a bug in android, I just need to know if it is a bug so that we wait for a solution and not spend more time on it.
