Android studio default vm options - android-studio

Android studio supports customizing vm options via
Help -> Edit Custom VM Options
My AS didn't display build info in Chinese correctly and I just set -Dfile.encoding=UTF-8 in the studio64.exe.vmoptions to fix it. I believe the default for the property -Dfile.encoding is GBK, which is the default encoding for my Windows 10 (chcp command told me so). However changing the default encoding for my Windows 10 to UTF-8 without -Dfile.encoding=UTF-8 won't work. I was wondering where AS reads the default vm options from.

Can't change "Emulated Performance: Graphics" setting in android studio

I'm trying to create a virtual device in AVD, however the graphics setting is grayed out. I've been able to successfully install HAXM and have also disabled windows Hyper-V. But the option is still grayed out.
I had the same issue and the answers here didn't work. Try this:
vim ~/.android/avd/Pixel_3a_API_28.avd/config.ini
Search for hw.gpu.mode = software change it to: hw.gpu.mode = host
Now it shows correctly in AVD manager as:
You have other options too: https://developer.android.com/studio/run/emulator-acceleration?authuser=1
I don't know exactly why but sometimes images with the Google Play Store don't allow you to configure graphics. Try with another image.
Another option is to edit the emulator ini file directly - under ~/.android/avd-emulator-name/config.ini
U will see the options:
hw.gpu.enabled=yes
hw.gpu.mode=software (or hardware)
Change as needed

No Android SDK found SDK tools directory missing

Basically I just installed for the first time in my life Android Studio android-studio-ide-182.5264788-windows.exe and when I open it I get:
Missing SDK, No Android found SDK found
I also checked this path: C:\Users\<user>\AppData\Local but I have not found and Android folder there because I was looking for C:\Users\<user>\AppData\Local\Android\Sdk
If I press next next finish I get:
Nothing to do!
Android SDK is up to date.
SDK tools directory is missing
I have also checked all kind of solutions posted on the internet but none of them fixed my problem.
I figured it out meanwhile but I forgot to update the question. Basically I had those issues because of the corporate proxy which was blocking some resources when installation was in progress.
The solution for me was to configure the proxy inside Android Studio under System Settings > HTTP Proxy. I have set it to Manual proxy configuration.
Besides this I also had to configure some security certificate inside the Java Version which was used by Android Studio. I used this code to do that: https://knowledge.digicert.com/solution/SO4085.html
The last thing was to run this: sdkmanager --licenses. I tried first in cmd but it was not working, I don't know for what reason but after I tried in Idea it worked.
After all of these, it worked. I had a small issue with the .. but it got fixed after I went in Setings > Build, Execution, Deployment > Instant Run and disabled Instant Run.
Download the zip file: http://dl.google.com/android/android-sdk_r24.4.1-windows.zip
Unzip it to SDK directory, and files like this:
D:\Android_sdk\platforms
D:\Android_sdk\tools
D:\Android_sdk\SDK Manager.exe
D:\Android_sdk\SDK Readme.txt
Restart Adnroid Studio, Configure->SDK Manager
Then you can change the Android SDK Location to your SDK path
After installation Click on configuration Go to SDK manager -> SDK tools and
uncheck “Hide Obsolete Packages”
Refer the image
after that check the mentioned package and install it –
C:\Users..\AppData\Local\Android\Sdk\tools\bin is created or not.
After creating project
Go to Tools
AVD manager
Your virtual device -> Create virtual device
Select Hardware :- Nexus 5x (Resolution)
Next
Check the latest or download latest one (OS)
Next
As it is default settings
Launch Virtual device
network adapter ipv4 settings or proxy.. I checked that, then it solved.

Windows Phone 8 Emulator in VMWare Fusion on OSX

I am attempting to launch the windows phone 8 SDK emulator on my Mac so that i can do simple web testing of mobile websites i build.
I have followed several guides and they all say the same thing.
Such as:
6. Once the content (list of files and folders) is displayed, find the VMware virtual machine configuration file – the file with the .vmx extension.
hypervisor.cpuid.v0 = “FALSE”
And this guide proved to be quite useful to get it setup:
http://developer.nokia.com/Community/Wiki/Windows_Phone_8_SDK_on_a_Virtual_Machine_with_Working_Emulator
I was able to get Hyper-V support enabled and I have even managed to open the Windows Phone 8 Emulator directly from the Hyper-V Manager. But in this state it is missing the chroming, the buttons, and when the mouse goes across the screen it disappears. The solution to this is said to be launching the emulator directly from Visual Studio.
My problem is when ever i try to launch the emulator from Visual Studio it creates a new image and then goes into a boot look where it keeps crashing and restarting over and over again.
When viewing the Hyper-V event logs i see this error:
'WP8SDK720P' has encountered a fatal error. The guest operating system reported that it failed with the following error codes: ErrorCode0: 0xC000021A, ErrorCode1: 0x88EB9150, ErrorCode2: 0x0, ErrorCode3: 0xC0000022, ErrorCode4: 0xD203BC. If the problem persists, contact Product Support for the guest operating system. (Virtual machine ID 50607D9A-6E23-4369-9D89-2730614219BA)
How can i get past this error?
In the end I found a solution, I managed to launch the original Windows Phone VM image directly from the commandline with this command:
"C:\Program Files (x86)\Microsoft XDE\8.0\XDE.exe" /vhd "C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v8.0\Emulation\Images\Flash.vhd" /name WP8SDK720P
I created a new text file with notepad and put this command in it and saved the file on my desktop as a .bat file. This way i can just double click the shortcut and launch the sim.
Hopefully this helps someone else out there. In this way, you don't even need to start visual studio to run the emulator, it makes it much simpler if all you are using the emulator for is testing web-apps.
N.B. if you press FN+DOWN-ARROW you can enable the keyboard to work in the sim.
Follow these steps and see if it might help you to fix the problem.
Step 1: Shut down the Guest operating system (Windows 8 in this case).
Step 2: Open the settings for the VM and select Processors. Look at the left pane and see if you have CHECKED the option "Virtualize Intel VT-x/EPT or AMD-V/RVI" under the Virtualization engine section.
Step 3: Open the configuration file (Windows 8 x64.vmx) for the VM and check if you had added the following line of command (hypervisor.cpuid.v0 = "FALSE") to it as shown in the screen shot. You will generally find the file at the location where the virtual hard disk is placed.
If every thing is right, check to see if you had installed Visual Studio 2012 Update 3 (if you are using Visual Studio 2012 as your IDE).
Hope this helps to fix the issue. If you need more information on how to create a VM for developing windows phone 8 apps, there is a great article on nokia developer forum. You can find it here
Happy Coding!!

Where are the scan settings stored on ce 5.0 MC9090? They are not in the registry that I can see

We are using MC9090's running CE 5.0. We are using a program called Wavelink Studio Client to access our scan application. Studio Client is different and not the same as Wavelink Telnet CE. Wavelink Studio is only a "Go Between" and does not hold any settings. The Wavelink Studio basically looks at the scanner .dll and pulls settings from that.
My problem is that I have an Interleaved 2 of 5 barcode with 16 length. The MC9090 comes with two demo programs ScanWedge and ScanSamp. I can modify the length for int 2 of 5 in either of these programs and my barcode will scan through Wavelink Studio Client. However, after a warm boot I lose all my settings since these are just demo programs.
So, I turned to DataWedge. Which uses its own config folder to store settings, but I assume loads the settings into the scanner .dll. My barcode scans perfectly in Studio Client when DataWedge is installed only after the DataWedge process has been "Stopped" then "Started". If perform a warm boot and DataWedge starts... my barcode will not scan through studio client until DataWedge has been Stopped, then my barcode will scan through Studio Client whether DataWedge is Started or Stopped.
My question is: Is there a script/command line/bat/etc. that I could use that would "Stop" DataWedge, then "Start" DataWedge after a warm boot? This is one way to solve my problem.
If anyone has any other suggestions, please let me know. I have repeatedly been told that the settings from ScanSamp and ScanWedge (demo apps) are not stored anywhere on the device. I believe they are stored somewhere though. Because, when I make a change on DataWedge, I can open ScanWedge and the settings happen there to. So there must be some central location where the hard scan settings are stored? I just need to be able to edit the settings in this location and have them stay there. I don't even need DataWedge if the scanner would hold the settings in the .dll that I specify from ScanWedge. With datawedge uninstalled, I tried changing my settings in ScanWedge then using RemCapture to capture all the settings from the device.. I then loaded those settings onto another device to see if it would load the scan settings, but it did not.
Set the options in ScanWedge. Then Use "Remote Registry Editor" that comes with Visual Studio 2008 and go to this path: [HKEY_CURRENT_USER\Software\Symbol\ScanWedge]
There you will see the various settings for ScanWedge. To persist these settings over warm & cold boot do the following:
Open Notepad on the PC.
Type the following registry entry:
[HKEY_CURRENT_USER\Software\Symbol\ScanWedge]
"AutoEnter"=dword:00000000
"AutoPIE"=dword:00000000
"AutoTab"=dword:00000000
"Binary"=dword:00000000
"Data"=dword:00000001
"Escape"=dword:00000001
"Prefix"=""
"Suffix"=""
Save the file as scanwedge.reg
Place the file on your Terminal in the \Application Folder using ActiveSync.
Cold boot the terminal.
NOTE: A cold reboot will erase all files, except the application and platform folder. Save your files before cold booting.
Hope this helps.

Add windows encoding to Eclipse on linux

I have a legacy project which has all the source files, templates, properties written in cp1250 encoding. (Windows 1250 - central european). Recently I switched from Windows to Ubuntu and found out, that fresh installation of Eclipse 3.5 doesn't have cp1250 in neither project properties nor workspace settings. How do I install new encoding to be recognised by Eclipse?
Now that's just typical, a minute later I send the question I find out that the drop-down menu can be also edited, so it's just simply matter of writing cp1250 in there, hitting OK and voila, problem solved. Eclipse even rerenders opened editors to show applied encoding right away. Problem solved.
