Android Cuttlefish Device Not Booting - launch_cvd Command Not Working (Error: run_cvd returned 23)

I have built a custom ROM that I'm testing on Android Cuttlefish, but when I go to boot the device on the command line using the launch_cvd command, I get the following errors:
[assemble_cvd ... fetcher_config.cpp:212] Could not find file ending in kernel
[assemble_cvd ... fetcher_config.cpp 212] Could not find file ending in initramfs.img
run_cvd returned 23
Subprocess 39641 exited with error code: 23
The main issue seems to lie in the 'error 23' that is returned by run_cvd.
I have tried Google searching and browsing popular forums where Android is built and debugged (XDA Forums, Reddit, StackOverflow, the Android Building Google Group, YouTube, and the web in general). I have also posted on Reddit and will post on the Android Building Google Group. Additionally, I have looked through the source code for Cuttlefish on Google's Git repo to find why the program is outputting the error to no avail.
Lastly, I read through the logfiles of Cuttlefish to see the errors outputted by Cuttlefish. The kernel.log file seems to show the kernel booted successfully (despite the command line saying that it couldn't find the kernel file), I would imagine the same is true of initramfs.img, but I have no way of confirming that initramfs.img was successfully found by launch_cvd. The logcat file is empty (likely because the Cuttlefish failed to boot) and launcher.log simply reproduces the output on the command line (which contain the four errors I listed above).
Could anyone help me troubleshoot this issue? Your help would be greatly appreciated!

Do ps -A | grep crosvm to see if crosvm is running already.
If it is do stop_cvd || true or kill crosvm process with process PID.

Delphi Android: After adding service to app icons and splashscreen images disappears

I've got a massive error. When I add to project new local service - my main app dosent lunch. This errors I got:
[PAClient Error] Error: E2312 Unable to execute '"C:\Users\Public\Documents\Embarcadero\Studio\17.0\PlatformSDKs\android-sdk-windows\build-tools\26.0.1\aapt.exe" package -f -M "D:\a\Android\Debug\asas\AndroidManifest.xml" -F "D:\a\Android\Debug\asas\bin\asas-unsigned.apk" -I "C:\Users\Public\Documents\Embarcadero\Studio\17.0\PlatformSDKs\android-sdk-windows\platforms\android-26\android.jar" -S "D:\a\Android\Debug\asas\res" -A "D:\a\Android\Debug\asas\assets" "D:\a\Android\Debug\asas\library" "D:\a\Android\Debug\asas\classes"' (Error 1)
[PAClient Error] Error: E2312 D:\a\Android\Debug\asas\res\drawable\splash_image_def.xml:2: error: Error: No resource found that matches the given name (at 'src' with value '#drawable/splash_image').
When I go to the Project -> Options -> Application I cant see any of icons or splashscreen images, they disappears. When I add this files manually - app is compiling without errors and starts, but only show black screen for a half second and shutdown. Without adding to project a service everything works very well, app starts normally. I tried reinstall Rad Studio - and nothing changes... In about month ago I created app with service and Delphi works fine. Im using Delphi 10 Seattle.
I dont know what I must do... my project stuck. Please, help me...

The problem was in Project Menager (upper right corner). To compile and run application correctly you must double click at main app name. When you did it, name of main app is bold. Then - everything is working very well. Thats all.

Error when updating Android Studio

When I try update my Android Sudio I get this message:
Temp. directory: C:\Users\Rick\AppData\Local\Temp\

The file Android\android-studio\plugins\gradle\lib\gradle-tooling-extension-impl.jar is probably in use by some JVM process (shown as java.exe in Task Manager).
Solution that worked for me was to close the updater and close all java.exe processes in Task Manager, then open Android Studio and try updating once more. This time the update should go all the way through.

A workaround:
1-Close Android Studio.
2-Right-click "Android Studio" icon and select "Run as administrator".
3-Go to "Help->Check for Update..."

There is no way for updating anything without the rule of updater. And the rule must be administrator or super user.
P.S.
As how it's name, updating is updating, renewing or deleting. Then it knows what it takes.

I was getting the exact error you getting. I left my PC on over night and clicked retry and it worked. Very strange. I also tried using:
handle - http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx
and
Process explorer - http://technet.microsoft.com/en-us/sysinternals/bb896653
to check what is locking that file and they both showed nothing. That is when I clicked retry and it worked

Graphic is disposed Exception

I am getting the following exception stack trace when I open the ADT/Eclipse:
org.eclipse.swt.SWTException: Graphic is disposed...(remaining trace here is quite long)
The corresponding messages in the Event details dialog are as follows:
Exception while dispatching event org.osgi.service.event.Event
[topic=org/eclipse/e4/ui/model/ui/UIElement/toBeRendered/SET] to
handler
org.eclipse.e4.ui.services.internal.events.UIEventHandler#7f6e8e26
Error while loading editor
Unhandled event loop exception
Just prior to these errors I was copying XML files form one project to another.
I have subsequently deleted every XML that had been copied but still getting the errors.
Am new to the ADT have read around a bit have not found any solutions.
Also, this is the first message to appear when opening ADT:
System property http.nonProxyHosts has been set to
local|.local|169.254/16|.169.254/16 by an external source. This
value will be overwritten using the values from the preferences

Performing a clean and refresh on eclipse (in terminal CD to Eclipse.app\Contents\MacOS then ./eclipse -clean -refresh. ) removed the error temporarily . Once I updated to eclipse Juno the error disappeared altogether. Hope this helps anyone with similar issue.

Cannot run Android application on emulator/device - activity doesn't exist?

When trying to run my application on the emulator I get an error from the activitymanager:
ActivityManager: Error type 3
My activity exists, is listed in the manifest (in fact, its the MAIN launcher activity).
Anyone know what this error means?

If you are running Eclipse try Projects-->Clean... and clean the project before running again.

i faced the same issue. I cleaned the project and removed the android:enabled=false in android manifest. This solved the issue.

Check "android:installLocation" in your AndroidManifest.xml.
"preferExternal" will cause the problem.

I got this error because I used invalid characters in my project name and Android didn't warned me about it so I had no idea that was the problem...
Example: "Thís ís íncorrect!"

nothing to worry about that it happens sometimes when activity manager unable to find activity of your app that means your target that is emulator is not started yet or may be because of following reason:
when you try to run your app on emulator you may be cancled in between building or forcefully closed your emulator.In that case when try to start emulator again it will sometimes not maximized.
now you have to restart your eclipse and then launch emulator and run your app now you will not face this type of error

Dont remember how I fixed this - most probably I wiped the local copy and re-checked out of svn.

ActivityManager: Error type 3
I don't know how true it is, but I used the same shared preferences file from another app..and got this error. I chose a new name for the shared preferences and the problem has gone away. It's working now

I had not enough space on my phone, that's why I had this problem.
So I cleaned it and go RUN )

I got this error when I mistakenly added a second application tag in my manifest as I was trying to add hardware acceleration to my app:
<application
android:hardwareAccelerated="true" />.
I added it above my actual application tag and I think this resulted in Android deploying an empty 'app' to my phone. It reported 'Installation success' in the logs and yet there was no launcher icon. It did appear, though, under Settings -> Apps but the only thing I could do there was to uninstall it. Hope this helps someone.

Thus, it seems there can be many reasons to see this error.
For those who can't fix it using the above mentioned methods:
In my case, i renamed the name of my activity (using F2 in Eclipse) and it is fixed.
