I am using visual studio for mac version 7.7.3(build 43), iPhone 7(12.3.1) and xcode(Version 10.1 (10B61))
I have installed Xcode on mac, not iPhone, is Xcode need to install on iPhone for debugging the app?
I already found the same issue on here. Restarted iPhone, Mac and visual studio as per the solution on that thread, but that didn't help me.

Update to the latest Visual Studio for Mac version (2019) as well as XCode version.

App Launch: The Huawei Lite Simulator supports only Lite projects

When trying to run my test app on a HVD emulator, I get the following error message:
App Launch: The Huawei Lite Simulator supports only Lite projects.
Meanwhile I've realized, that currently one can only use hardware or a remote emulator for such a project. But when trying to set this up, the Harmony OS Virtual Device Manager responds with 404:
Is there anything to do about it?
I haven't tried with DevEco Studio on Windows so far, but with Android Studio on Linux, which appears to be functioning now.
With HMS Toolkit version 1.0.5, it will ask for Huawei ID and then also lists devices in Düsseldorf or Ireland (where the one is a city and the other a country). However, there are currently only EMUI ROM available. It integrates better than before, but without an HarmonyOS 2.0 ROM, it still doesn't provide the expected environment.

Got the "Error launching application on" after flutter run

I am flowing the official tutorial to install flutter and run the default app on my iPhone Device. After I execute the flutter run, the app is installed and launched on my iPhone but the logs show the bellow error. How do I solve it?
Launching lib/main.dart on My iPhone 6 in debug mode...

Error launching the application on My iPhone 6. <-- Error Here
It happens that there are some process needed to Flutter plugin correctly run on physical devices. I struggled with that and finally found that the processes idevicesyslog and iproxy were being silently blocked by MacOS.
You may have noticed already a message liked this:
or a similar one for idevicesyslog.
Once I went to System Preferences -> Security & Privacy in General tab and allowed this apps, everything works. Note that this screen shows only the last app that you tried to run. So I'd recommend that you run flutter app with preferences opened so you can (hopefully) see the messages appearing and click allow.
MacOS may warn you one more time about the file being downloaded from the internet. Just click open and you're good.
The error do not show again after reboot the iPhone.
Same error -- Running fine through Xcode, when I ran with flutter CLI, the app would open, but the terminal log output would crash with the error as in the post.
I ran flutter update and simultaneously turned iPhone off and back on. After doing that, the below popup appeared (on mac).
I believe after the install finished, I ran the below (which I ran several times before updating flutter and installing the popup):
flutter clean
rm -rf ios/Pods
flutter pub get
cd ios && pod install && cd ..
run the flutter app using flutter run from command line, then the MacBook will ask for permission to open the app and app runs,
(lldb) warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance.
Error launching application on device-XXXXX.
Building & Replace with a newest version ios-deploy solved problems list aboved. Flutter SDK bundled a pre-built command ios-deploy in __PATH_TO_YOUR_Flutter_SDK_/bin/cache/artifacts/ios-deploy/, just replace it.

React native Android Project Not starting in emulator

i just created a react native project on windows, using expo. After Creating the project i ran npm start and then expo start the next logical thing to do is to press the a button which will launch, the project on the android virtual device, but instead it gave me this error Couldn't start project on Android: Error running adb: Error running app. Error: Activity not started, unable to resolve Intent { act=android.intent.action.VIEW dat=exp://192.168.43.148:19000 flg=0x10000000 }
when i tried running it on my android phone with the expo android app it ran smoothly, i don't know what to do please help thanks
I had the same problem and I got it fixed as follows:
Go to SDK Manager in Android studio > SDK Tools and check whether there is any update for Android SDK Build-Tools. If there is any, please make sure you update it.
Close any Android virtual device currently running and then go to Android Studio Virtual Device Manager and wipe the data of your Android virtual device.
Make sure you have enough internal storage allocated for your Android virtual device to install apps.
Check whether Android Debug Bridge utility is installed in your device. If not please install it. To install in mac, I used the below command (Assuming that you have HomeBrew installed in your mac device):
brew install android-platform-tools
Start your Android virtual device ( This step should be done before running the expo development server)
In the Developer options menu of your Android virtual device, make sure USB debugging option is enabled.
Finally, try running the development server by expo start and press on the button to run on your Android emulator.

"Installation or uninstallation is not working temporarily" error when trying to launch Tizen watch application from Tizen SDK

When trying to launch the native watch application from Tizen IDE, I see the strange message "Certain application categories, such as "Watch Application", cannot be launched by "Run As".
Indeed, I try to use Run As from the project local menu to launch my app. But how else I am supposed to launch my application on the emulator?
The emulator device (watch) is up and running, visible on desktop as a separate widget. It is selected. The signing configuration is set up.
On the console output I see the message processing result : FATAL_ERROR [61].
I also tried to launch through the created launch configuration but this results the same error message.
The IDE logs show the following stack trace:

Management: Installation or uninstallation is not working temporarily.
P.S. I add "eclipse" tag because Tizen SDK is very clearly Eclipse based IDE. Using Tizen IDE 2.3.1.
Watch face applications(Web/native) are never installed as widgets. You cannot see them in app menu.
Reason:
Within your tizen-manifest.xml file in your project, you'll find below line there
<watch-application appid="org.tizen.watchsample" exec="watchsample" ambient-support="true">
which makes your app as watch application and these apps are known as watch faces because they will be used in setting as the main watch in gear.
And on emulator, you cannot change the watch face on the home screen. Hence, you won't be able to test your watch application that way.
Had the same issue. My problem was certificate setup.
i followed there instructions: http://127.0.0.1:50224/help/topic/org.tizen.addon.certificate/html/dev_env/setting_author_certificate.htm
(link is from help and should work in browser when Tizen IDE is up, alternately you can go to Tizen IDE -> Help -> Help Content and search Certificate.
More specific: Distributor certificate i had was wrong (use the pass received by Samsung by email)
After fixing certificate, don't forget to right click your device in Connection Explorer and click Permit to install applications.

Unable to launch Android emulator from Eclipse/Linux

I'm using Eclipse Juno (build 20120920-0800) on openSUSE 12.2 to code Android applications.
I have installed the SDK by uncompressing it into my home directory (if I install the SDK via YaST package I can't download stuff unless I'm root). I installed ADT from Eclipse Marketplace, configured the path of the SDK and configured a couple of emulator configurations.
I can run and debug fine on my phone, and I guess the same applies to my tablet even if I haven't tried yet.
The real problem is that I can't run the emulator. Clicking on the bacarozzo debug icon prompts me to run the application on the device but doesn't show me available emulators.
If I open the device manager I'm shown with the virtual devices I created but I can't just start any. The progress bar reaches the end, I see no emulator screen and if I try to delete the emulator I'm warned that the instance is running... (OK in the screenshot there is only one, I already managed to delete the other)
I urge to test some GUI features in an outdated version of Android. I have done all the field tests of the business logic code in my program on a JB device and I know for sure that code works on any device.
Now I only need to be backward-compatible with preferences and layouts.
How can I start the emulator in Linux?
Just by luck I managed to run the emulator from console
djechelon#RAYNOR:~/android-sdk-linux/tools> ./emulator-arm -avd Emulator_cell
It came to life and Eclipse debug is detecting it as active device
