I have a helloworld android application. But it can't run.
(Same code ran well yesterday. I don't know what configuration I changed..)
When I pressed "run as android application" in eclipse, nothing happened.
I used command line to run it:
$adb install -rv HelloAndroid.apk
But nothing happened, either.
I can see my emulator from $adb devices
List of devices attached
emulator-5554 device
How can I find the problem?
try running these commands:
$adb kill-server
$adb start-server
and then retry. For some reason Eclipse has a hard time running the apks if the server is started before the emulator.

I am trying DUT debugging using adb in my ubuntu machine 20+.
when I try to disable-verity, I am getting the following error "/system/bin/sh disable-verity not found"
I tried reinstalling adb again , and I am running to the same issue.
I ran the DUT in different windows setups, it is running fine though
Anything I am missing?
Another thing I noted is: running just adb is giving segmentation fault, however running adb with other arguements is running fine. ie adb devices
I am running macOS Catalina, and have one Android emulator set up in the Android Virtual Device Manager.
Before starting the emulator, on a freshly rebooted system, if I run adb devices I get:
List of devices attached
emulator-5562 offline
After starting the emulator, adb devices returns:
List of devices attached
emulator-5554 device
emulator-5562 offline
If I fire up Expo and try to run on the Android emulator, I get this error:
Couldn't start project on Android: Error running adb: more than one device/emulator
It looks like the offline emulator-5562 is the problem here? But it's still there even after rebooting my computer. All the advice I've read (i.e. adb kill-server and adb restart-server) makes no difference. There are no Android devices connected via USB.
How can I delete the "offline" device? Or alternatively, how can I point Expo to the one actual Android emulator I have running?
Try this:adb -s emulator-5554 <command>
In android studio 3.6.3
This error indicates when I click on the Run button to install the program on the emulator.
Installation did not succeed. The application could not be installed.
Installation failed due to: 'device offline'
After a lot of searching, I found out that the adb had a problem and the emulator was turned off incorrectly.
I entered these commands in the cmd and the above error was fixed.
adb kill-server
adb start-server
adb connect [192.168.162.101]:5555
adb devices
List of devices attached [192.168.162.101]:5555 device
NOTE
This IP is 192.168.162.101, which has an emulator itself. If you want to run the emulator manually, you must get your emulator IP and replace it with 192.168.162.101, otherwise it should automatically follow. Implement the first two commands of the emulator on the adb
I was using the emulator. I just close the Android Studio and then opened it again. The issue was resolved.
Disconnect your phone and connect again. This was worked for me.
Hello i am trying to run my android app on eclipse and i have this problem:
The connection to adb is down, and a severe error has occured.
You must restart adb and Eclipse.
Please ensure that adb is correctly located at '/Users/giannis/android-sdks/platform-tools/adb' and can be executed.
any idea about the problem?
Since adb is installed and seems to be working, Eclipse is probably having a problem finding or starting adb. First, check that Eclipse has the right location set for the sdk (Window->Preferences->Android or slightly different on Mac). I think it should based on the error message. Then, if you still can't run the app from Eclipse, try starting adb from the command line with adb start-server.
EDIT: If the app still won't run after doing the above, make sure adb is able to find your device or emulator. Start the emulator or connect your device, then run adb devices from the terminal. If your device or emulator is not listed, adb can't connect to it. If it is an actual device, make sure USB debugging under developer options in the device settings is enabled.
I've been working to setup android studio on xubuntu. I'm able to find the device manually on the terminal, but when ever I run the application on Android Studio I get ADB waiting until it stops responding.
Thanks for the help, Ryan
The ADB daemon on the device itself might be the problem. Try to enter adb shell in the Terminal. That should give you shell access on the device. If you're able to use a command like ls, the ADB connection is working as intended.
If you're not able to open the shell or execute ls, the ADB daemon on the device is the problem. Try rebooting the device, and/or re-enabling USB Debugging.
If shell access is working as intended, Android Studio should work too. Try restarting Android Studio.
