Generic Ionic app doesn't load in AVD

My android virtual device starts up fine. But when it goes to load my ionic app it says: "app-name has stopped", "Open app again" after opening the app several times it says: "app-name keeps stopping close app". My app is the base tabs ionic app.
Ionic even says launch success...
I've tried different AVDs but none have worked. Here are the stats on my current one.
I've tried running it in with ionic run android -c -1 but all it says is
emulator: Requested console port 5584: Inferring adb port 5585.
emulator: Listening for console connections on port: 5584
emulator: Serial number of this emulator (for ADB): emulator-5584
EDIT: it works on Ionic serve just doesn't load on the android virtual device.

check if you have a service using that port or a program like skype that uses that port, then close or change the port it uses.
i had to close xampp in order to emulate android.

Checking use host GPU in the android SDK manager solved the problem for me.

Jenkins cannot connect to android emulator

I'm using Jenkins for continous integration on an android emulator to run instrumentation tests with the espresso framework. Unfortunately the server is not able to connect to the emulator. I have a master instance which delegates the push events from GitHub to the slave instance where the android sdk is installed. I installed the android-emulator-plugin and configured it like described. At first the Jenkins starts the emulator, but it cannot connect to it afterwards. This is the result:
I also cannot connect to the emulator when I'm on the slave machine. But if I use 127.0.0.1 instead of localhost the adb tool can connect to the emulator:
Is it possible to use 127.0.0.1 instead of localhost with the android-emulator-plugin? I already specified the enviorment variables $ANDROID_AVD_DEVICE and $ANDROID_SERIAL with no result. Any ideas?

I was fighting with it whole day. Just try to comment ipv6 in your /etc/hosts.

I fixed the problem by myself. I have checked out a fork on GitHub, which uses 127.0.0.1 instead of localhost. This did work for connecting to the emulator but not for running the instrumentation tests. I do not use Jenkins plugins for the connection anymore. I make the build with a shell script which contains all commands to start the AVD and the gradle tasks. Works fine for me. But thank you for the advice. Maybe I will try to comment ipv6 aswell, if I have the time to work on the Jenkins.

How to fix the error "Unable to open debugger port " in Android Studio?

Error running Android Debugger (8600):
Unable to open debugger port (localhost:8600):
java.net.SocketException "Connection reset"

I was able to fix this with these commands:
adb kill-server
adb start-server

Try Restarting ANDROID STUDIO (Worked for me)

In my case, there was another service running on my laptop(Windows) that was using the port 8600. I opened Task Manager and stopped the service. Now, I could debug my application normally without the above error.

I solve the problem by checking my localhost.
Making sure 127.0.0.1 localhost.

For me this problem started when i upgraded my Android Studio to new version.
Please go to options menu Build and choose Clean Project.
That is it project started to run again and error was gone.

I tried other answers (e.g. restarting Android Studio) but they didn't solve this for me.
I had accidentally selected MTP (Media Transfer Protocol) in my Developer Options/USB Configuration. It started working once I set it to PTP (Picture Transfer Protocol).
EDIT: On reflection it's probably just that I changed the protocol because I've had the same issue since while on PTP. Hence I'm suggesting that the real answer is to change the protocol on the phone and, if you might need it, don't forget to change it back.

It could be that you need to wait for your code to stop compiling before you attached the debugger. I had a similar error and all I needed was patience.

If you using WiFi debug:
Exit ANDROID STUDIO
adb kill-server && adb start-server
adb tcpip 5555
adb connect [your wi-fi IP]:5555
Start ANDROID STUDIO

I did spent quite an amount of time by trying below things:
Re-installing old(3.6.3) and new(4.0.1) Android studio and Android SDK's
checking all the security things in newly installed Mac OS Catalina
Checking all the developer options in my physical android device and AVD
And all the things mentioned in this post as well: https://medium.com/returntrue/android-studio-cant-bind-to-local-8600-for-debugger-%E3%81%A7%E3%83%87%E3%83%90%E3%83%83%E3%82%AC%E3%83%BC%E3%81%8C%E6%B0%B8%E4%B9%85%E3%81%AB%E8%B5%B7%E5%8B%95%E3%81%97%E3%81%AA%E3%81%84%E3%81%A8%E3%81%8D%E3%81%AB%E3%82%84%E3%81%A3%E3%81%9F%E3%81%93%E3%81%A8-8f5dd9c8ca70
Finally a small change in my /etc/host file resolved this issue. I commented from 0.0.0.0 and ::1 for localhost local DNS entries and enabled only 127.0.0.1

tizen emulator not connecting to device

Hi I am trying to connect the Tizen Emulator version : 2.3.0 Rev2 to an android device.
I downloaded the files for apk files from here. I have done the port forwarding like shown below before starting the emulator :
adb -d forward tcp:8230 tcp:8230
But even after starting the Emaulator still the HostManagerForEmul shows status as disconnected.
I was following the complete instructions from the youtube video found here.

A couple things to try...
If Gear Manager is installed on the Android handset, uninstall it. Gear Manager is not compatible with HostManagerForEmul.
Restart sap-server from the emulator.

I have same problem, after struggling I have finally connected
Here is solution , Go to package manager install both highlighted from extension SDK as shown in picture
after installing connect android phone install apk provided in tutorial and run
adb -d forward tcp:8230 tcp:8230
Now delete emulator and make again, after reboot it will install extension tools and on first boot it will show like this
After that it will reboot again automatically , and on Android side it will show Connected. Done :)

Error in running sample android application on an emulator

I am new in android development.
I created the sample hello world and try to run it on a emulated nexus 7 system.
I am using android studio 1.8.14.
When I run the application, I am getting this message in andoid studio:
Waiting for device.
Target device: test_nexus_7 [emulator-5554]
Uploading file
local path: C:\Users\m\AndroidStudioProjects\MyApplication\app\build\outputs\apk\app-debug.apk

DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.example.m.myapplication"
Error: Could not access the Package Manager. Is the system running?
what is the problem and how can I fix it?

It may be a known bug. Does this solve your issue?
"2 Error: could not access the package manager. Is the system running?
You may have gotten this error while attempting to run an Android application on an emulator or device using Android Studio. The most common cause of this error is simple: You have to manually unlock your Android Virtual Device by swiping the “lock” icon on the screen. Security measures prevent the emulator from letting you connect the debugger before doing this."

Other suggestions: wait for the emulator to fully start up, which could take longer than you expected, or try debugging on an Android device, which is faster and has access to native functionality, rather than in an emulator.
