Waiting for the HoloLens Emulator's OS to boot up every time I make some changes to my app and I recompile can be annoying. Is there a way to deploy a new build to an already running emulator?
Yes, just don't shut down the emulator. You can push the Stop button in Visual Studio, make your changes in Unity and rebuild. Your open project should detect the changes and ask you to reload the project. Hit the Play button in VS and your new code is redeployed to the emulator.

When I launch the app again after loading it from android studio and closing it once, a white screen is shown. The app is not launched when I start it for the second time.
Why is it so?
it is not clear what you are trying to say but you can use the run option in Android Studio to select your target device also what you can do is you can export it as an APK from the android studio and run it directly on your device(not preferred for testing your application though)
I'm having a devil of a time using the Android Emulator on my new M1 Mac. My Android project compiles fine, and I can run it on a hardware device. But I'm not able to run it on the Emulator.
I followed instructions carefully, and set up an arm64-based emulator running API 31. When I press the "Run" button in Android Studio, the emulator opens and boots normally. However, Android Studio is never able to launch my app on it. I see a message "Waiting for all target devices to come online", and that's it.
I have of course tried restarting the emulator, restarting Android Studio, rebooting my computer, and wiping the data from the emulator. I have also made sure that Developer mode is enabled in the emulated Android environment and "USB Debugging" is turned on.
Another suggestion I saw was to un-check "Enable ADB Integration" in Android Studio. This option doesn't exist in my copy of Android Studio, although I did some further research and found that it is now called "Use libusb backend" instead. It is unchecked by default. I tried checking it anyway, and that didn't help.
I'm at a loss as to what to do next. I really need to be able to test my app in the emulator as my inventory of physical devices is fairly limited.
Thanks,
Frank
Download Android Studio Preview, create emulator (API 30 or S), now you can use emulator on both preview or stable Android Studio.
I have a very big problem using Android Studio.
Every time I make a code changing, I have to check if all has gone well launching my app; but as soon as I click the "Run app" or the "Apply changes", it's the end: it starts the Gradle build process, which take even 30 minutes to complete, and furthermore Android Studio take the full control of my computer, not allowing to do nothing anymore (like open the browser, open notepad++, and so on...).
Can anyone help me?
Thanks
If you use Eclipse you won't have this problem anymore. but if you want to stick with android studio and gradle you can run your emulator and gradle once and whenever you want to compile your code run it on the already built gradle. this means that do not close the emulator and run your program on it again and again. this way you will not have to spent alot of time on loading the emulator and gradle
Android Studio is not a very light software.It uses a lot of your system RAM and CPU power.So if you are using an old system then it is obvious that android studio will run slow.If possible then upgrade your system.
And one more thing it's better to use actual device rather than Virtual Emulator for our application working test.
I am using Android Studio 1.2.1.1 on Ubuntu OS
while debugging an app the run button stops relaunching the app.
I noticed that on the run console [next to the android and TODO consoles] the each launch causes another app to start.
Sometimes I can solve this problem by
stopping all the apps
detaching and reattaching the device
relaunching the app
Other times relaunching Android Studio helps
I would gladly endorse a better less speculative answer
I follow instruction on https://msdn.microsoft.com/en-us/library/azure/ff683670.aspx to debug a project in Azure Emulator in Visual Studio 2013. But after clicking "Show Compute Emulator UI", I can not find "Debug" On the Azure compute emulator (express) menu bar. What is the problem? Thanks for help.
You need to make sure that you have the correct project set as the Startup Project.
For example:
The Azure project here includes a Worker Role that is implemented in the Azure.Processor project.
With the Azure project as the startup project, hitting F5 will build the package, deploy it to the emulator, start it up and attach the debugger.
I don't think you need to click "Debug" in emulator UI. I think the document may be wrong. Just clicked "F5" to launch your application from VS2013 if it's built in debug. Once the emulator was started and your application was running, you can begin to debug by adding breakpoint.
