I try to run my app in android emulator. From the begining, everythigs works fine. I create new device in Android Vrtual Device Manager, then i run the device. After a while i can see an emulator with mobile skin - that's all, nothing else happens. The device has black screen and in the Android Monitor I see this:
screen from Android Monitor
When i try to run my app I recive this:
screen from selecting deployment
When I try to run app from this window, somethig is going to happen. I have to wait long long time but finally, android is started on the device but meanwhile i recive error "Session 'app':Error Instaling APK. Sometimes app will run, sometimes not, but everything works very very slow. When i run app directly (without running device from AVD Manager), app is bulided and then i see a process "Waiting fro target device to come online", emulator runs but with black screen.
I have no idea what to do now. I reinstaled Android Studio twice - always the same result.
I have to add that a few days ago everythings works perfect - very fast and without problems. Recently I was installing Ubuntu on a new partition, I've done some changes in widows driver manager. Maybe this is a reason?
What I should do now? Thanks in advance

I am trying to build an app. I am using flutter as the framework and VS Code as my IDE. I also have an android emulator installed via android studio. I am trying to implement authentication. If i run my app it opens in the emulator and works just fine. Now i want to test if a user stays logged in when the app is closed (not running in the background) and reopened. However if i close the app in the android emulator, the whole process stops and there is no icon of my app on the home screen with which i could restart it. I have to "run and debug" again in VS Code to restart the process. Is there any way to start the app again via the emulator phone?
I updated the emulator and the flutter package, i changed emulator devices. Did not solve the problem.
Because when your app is disconnected from debug - you can use hot restart its consider as app is kill and open again - here having a problem with flutter if you disconnect from debug your all assets will be remove from entire app. Another option - if you want to test your app then make release app and installed in physical device
You can try to run your app from VS Code itself.
Use this bottom Menu button to launch emulator:
Select your Emulator from listed / Create a new one:
Hope it helps!
I'm new to flutter, I developed apps in Android Studio for ios devices, and they run perfectly when I run them from Android Studio onto the real device. However, if I try to run the app from the iphone itself (from the launcher icon), the app imediately closes and doesn't run.
Why would this be? Is there anything I can do in the code to enable the app to run from the phone itself, not just through running it in Android Studio?
Thanks for any help!
I am studying about phonegap. I run Android Virtual Device Manager, selected a device and click started. After starting android emulator finished loading.
I saw emulator-arm.exe in the task manager and it took some memory resource. But no emulator appeared. After about 10 seconds, emulator-arm.exe disappeared from task manager.
I couldn't start Android Emulator. Please help me! Thank you!
Did you use the latest version of the platform-tools and the image? Run "android" script in your android-sdk/tools folder, and update all items related with emulators. Then, run "AVD Manager" in the root folder of the SDK. Then, create a virtual machine based on a real device of your choice. Then, run and wait, emulator takes some time to appear.
Other better choice would be use Genymotion emulator, which has more speed and stability. Good luck!
I have been working for a year with eclipse, but after I upgraded to the Android SDK Tools v20, the emulator doesn't work (absolutely nothing happens). I have everything installed as always, but when I run the emulator, it doesn't appear anymore (althought just after installing SDK Tools v20 it worked twice).
I have even installed again the SO (Linux Mint), after I tried everything I read here, at curiously, the emulator worked 4 or 5 times. The symptoms are these:
-when I run the app, nothing happens in my laptop, but if I put the mouse over the green triangle for running the app, it says: run (already running)
-I've tried to kill the server with adb but doesn't work
-If I list the devices with adb devices, it doesn list any device, even if eclipse says that is running the emulator
-I've tried two different versions of Eclipse: Juno and Galileo, but it's the same
-I've tried to run an emulator independently, but it doesn't work
-I've created several AVD, with different APIs and characteristics, but nothing happens
Does anybody has any solution to this?
Thanks
Good idea to make :Project ->clean
Window ->AVD Manager -> pick your virtual device ->Edit-> Snapshot(make sure is disabled) ->Edit AVD (try again, if still not working , then try to launch the emulator directly from AVD Manager -> Start).
Once the emulator is starting then you can check back the snapshot option again.
If nothing of that works, then try to uninstall/Install SDK again.
I downloaded Android SDK and using Eclipse for development.
I am trying to run HelloAndroid program.
Everything goes fine till the installation of the application.
[2011-02-20 23:34:31 - HelloAndroid] Installing HelloAndroid.apk...
[2011-02-20 23:34:58 - HelloAndroid] Success!
[2011-02-20 23:34:58 - HelloAndroid] Starting activity com.example.helloandroid.HelloAndroid on device emulator-5554
[2011-02-20 23:35:01 - HelloAndroid] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.helloandroid/.HelloAndroid }
Above is, what is there in the console tab.
As soon as I take my pointer to the Menu button on the emulator or after say 2-3 min... I receive the below mentioned error from windows.
emulator.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
Measures taken to solve this problem :
I turned off my firewall and tried running it, but it in vain.
I closed the emulator and re started it from the Window -> Android SDK and AVD Manager, but in vain. I also tried checking the
wipe user data
checkbox in the Manager window, but in vain.
PS: Only once till now the application did run properly and showed me the Hello Android Message but that too crashed. After that, the application has never even worked. It shows the home window with date and time, and crashes before showing the above mentioned reasons for the crash.
Also, I use Windows xp SP 2.0 and Eclipse 3.6.1. I choose min-sdkVersoin as 10.
Thaks in advance
Try Minimum API level=8 (that would be Android 2.2.)
Failing that. Note the Eclipse and JVM versions in the system requirements. I would stick with Eclipse "Classic" (3.5) if you're just trying to get your feet wet. Ensure that your JVM version is compatible.
I have found that Google don't really make things "linear" when it comes to installing stuff sometimes. Failing that, uninstall the JVM, and follow my deployment instructions I have written here. As this is exactly what I did and never had any probs. Hope this helps.. good luck!
Have you tried running a new AVD (Android Virtual Device) from the SDK manager (without loading any apps)? Does it crash too? If it does, then you might think reinstalling SDK again cause somethin aint right.
