Successful workaround: Kill the ADB process if it does not return within 120 seconds.
le...@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?
