Running my application on another Windows machine results in a blank window. I works fine on the development machine.
I have included all the dll-files + data folder + 3 extra dll files mentioned on the Flutter website.
I have also ran "dependencies" on the resulting .exe file and can't see any missing dll's.
Compiling the "mydemo" application works fine, so I assume there are some other external files my application needs.
I have tried looking through the output of "flutter run -v" to find any clues of extra files needed, but can't see anything useful.
What is the preferred way to tackle a problem like this? How can I find out what files/resources are missing to distribute my app? Is there a way to use the "debug" version on the other machine instead and bring out the debug console window? I would guess that would show me errors when the app tries to load the missing resources.
Check if any package you depend on has some additional file requirements: for example, I'm using sqflite_common_ffi in some of my projects, which needs an additional DLL file to run. I don't know what you're referring to 'dependencies' ran on the EXE, though.
In any case, when I can't get any good output or error from a project, I do this: open up Windows prompt, go to the directory where you have put all the required files, and run
your_exe_file >> logFile.txt 2>&1
which will output the standard output and the standard error to the file. The log file name and extension don't really matter, it will be a simple text file.
For example, if I dont put the additional DLL for sqflite_common_ffi in the same folder of the compiled EXE, the output of the command above will specifically mention the name of the DLL that is missing.
if you got your project through a repository to run on another windows machine, use the command "flutter pub get"

I have created a project using Robot Framework in Eclipse via RED. I want to know how can I run this project via Windows Command Line, so that I can create a Jenkins job to run it at a particular time ? I have tried using the steps for running Eclipse Project from command line via Debug mode, but it is not helping.
Please find the project structure below
I also tried to reach this location and run this test suit using the command
Robot Test_Suite.robot, but then I'm getting below 2 errors
1.) Importing test library 'Excel_Library' failed: ImportError: No module named Excel_Library. This file is a python file which I have written to support Excel operations and it is present at below location in the project -
2.) No Such File Or Directory - Path_To_External_Input\\External_Inputs.xls
This file contains the input which is being read before performing operations related to test suite and it is present at below location -
Do I need to add those in the command line if so how to take care of that ? This project run smoothly from eclipse but only problem is coming from command line.
It seems that you are able to run robot correctly, although I would prefer lowercase R with robot command.
1) I think you have misspelled the library name. If it's a pip package, try ExcelLibrary instead, and check that you have installed it by pip list command or equivalent.
2) Please check the path. Without additional info on how and where the file is called and where the file is located are needed.
I have installed the flutter folder in Program Files (x86) and have added the .../flutter/bin directory to path. Running flutter doctor in the flutter_console.bat window or just a normal command prompt window gives nothing
and running as admin in either gives me the error:
Updating flutter tool...
\flutter\.pub-cache was unexpected at this time.
What do I do? Thanks in advance for any help.
You shouldn't put Flutter in Program Files. These folders are not writeable by non-Admin users so may fail when trying to write files if you're not running your console/editor as Admin.
Cut flutter folder from Program Files (x86) to Program Files. It has problem with x86 but works fun in x64 directory. And update the environment variables with the new path.
I had mine fixed by just removing the special character from the directory name.
I organize my folders with numbering and parenthesis like so
1) xyz
2) yza
3) aws
...
25) flutter
I changed it to
1) xyz
2) yza
3) aws
...
25 flutter
don't forget to change it in environment variables too
Ok so this is probably not the way to go about it but what I did to solve this problem was remove this line
SET pub_cache_path=%FLUTTER_ROOT%\.pub-cache
from flutter/bin/flutter.bat. I then went through the installation process and once everything was working changed the flutter.bat file back by adding the line again and then ran flutter again. I got no errors from doing this and I appreciate that this is probably not the correct way to go about solving this problem but it worked for me so I am posting it as the answer if others want to try it.
1.Set the environment variable by copying the bin directory ex: C://programfiles/flutter/flutter/bin
2.Go to Control panel -> User Accounts -> User Accounts-> Change environment variables -> Choose User variable -> Path -> Edit -> New -> Paste the link -> click ok
3.Restart Computer -> Open powershell -> Type "Flutter"
4.It should be working now.
1- First make sure that you running cmd or powershell as admin.
2- If didn't work try to restart PC.
3- If didn't work try to move the flutter folder to another path and make sure that you did the required changes on Environment Variables.
4- If didn't work, just delete the cache folder in "flutter\bin" and try again by writing
flutter doctor
Also as a note, try not to put your flutter directory inside the special directories which need a special permissions like Program Files.
I had originally installed it in d:\Program Files (x86) which is NOT the system folder, but an alternate install location that does not require elevated privs, and I was getting this error. I moved flutter to just d:\flutter and it worked. I don't know if it was spaces or the parentheses that was problematic.
Extract the zip file and place the contained flutter in the desired installation location for the Flutter SDK (for example, C:\src\flutter; do not install Flutter in a directory like C:\Program Files\ that requires elevated privileges).
You are now ready to run Flutter commands in the Flutter Console!
I have a Java rich client desktop app. that I want to distribute on some computers at work, but I've never done something like this before. People aren't too computer-savy at my workplace and since it is a student job, I won't be there for much longer and I'd like it if I could make my program easy to run by making it runnable when people double-click on it.
I also don't want to have to manually install a JRE to have it run. Basically, what I'd like to know is how to make my java application runnable easily by double-clicking (even if it's only on windows, it's okay). I'm pretty sure I'm going to need to package the correct JRE version alongside, but I don't know what's the correct way of doing this.
I read on some sites that you should not package a JRE along with your program because it makes people have multiple different versions, some of which are outdated, and it causes security issues, but this is not a problem in this case since the computers that are going to run my application are not connected to the internet and are only used to run this program anyway.
Somewhat related question: Since my application is currently an Eclipse project, I get my resources such as icons, images, SQLite database (for read and write), etc. using relative paths (e.g.: img/test.png).
Am I going to have to change any of those paths to have them keep working even while packaged?
What you're looking for is a JAR file. In eclipse, it's quite easy to make a Jar file. Specifically, you'll want to right click on your project, go to Export, and then select "Runnable Jar." Be careful with paths to folders. You may need to keep a resources folder next to the Jar file. You may need to provide some more specifics to get an exact answer on that. Typically, a Resources folder is located in the same spot as the JAR file (in the same folder on your computer).
A better option for easy install of a Java app. with a GUI is to launch it using Java Web Start. For the user, JWS is the 'one click' installation option that can (install & launch the app. then) add desktop shortcuts and menu items. A JWS launch would mean some more work for you, but it is a breeze for the end user.
To ensure a suitable JRE is present to run the app., use deployJava.js (see the JWS link for more details). The script would need to be reconfigured to get the JRE installer from your local network - the default is to get it from Oracle.
Most of the resources should be packaged in Jar files and supplied along with the app., but for the DB, use the JNLP ExtensionInstallerService to call the DB installer.
..Java Web Start is kind of a link (or I can make it a shortcut on the desktop) that the users will click to either install the JRE and run the program if the JRE isn't installed, or just run the program if the JRE is present on the computer.
The way it would work is to have a web page on the local intranet. When the user visits the page, the script checks for a suitable JRE.
If it is present, it writes the link to the launch file.
If there is no JRE, or the version is too low, it will guide the user through installing it (just a matter of them clicking 'OK' when prompted). Then it will put the link to the app.
I can then configure the link to grab the JRE from the server on our network.
That's the part where you need to reconfigure the script. AFAIR the script exposes an URL at which to look for JREs - that can be changed to point to a place on the intranet.
..So "Web" is only just in the name, the computers don't have to be connected to the internet to have this work, right?
Yes. JWS is a great launch technology for Java rich clients, but is a poorly chosen name.
To make the problem run by double clicking it you can distribute it as a jar file or a batch file to call the jar file.
For the installation part you can make a batch file that checks if java is present and then call the installer if it isn't.
Edit:
The batch code:
IF DEFINED JAVA GOTO ok
java-installer.exe
GOTO end
:ok
your-application.jar
:end
If you are finding it tough to implement the above mentioned methods. You can proceed with this simple approach.
Create a folder lib at a location. Place all the jars that your application uses into this. If you are able to create a jar for your application, you can very well place your application.jar into the lib folder too. Create a batch file at the same location that will contain the java command for your main class in it. The text within your batch might look something similiar to this :
set path="\lib\"
java -cp %path% package1.package2.MainClass
If you have any other dependencies, for ex: if you use images in your code under img/icon.jpg. Then you just have to shift the img folder to this location too.
Just zip these files using winrar and share it across. Running the batch file after extracting the zip would launch your java MainClass irrespective of the location in which it is placed in the client system.
PS : If you are unable to create a jar for your application and placing it in lib folder, just copy your bin folder with class files and paste it in the location and change the batch file accordingly to look for classes inside bin.
I'm writing a build script to compile and package my app, and I'd like a nice way to get the full path name of the .app created. I can't find any command line tools other than xcodebuild, which doesn't appear to have much in the way of inspecting an Xcode project. My full compile command is
xcodebuild -sdk iphoneos2.2.1
so it'll build with the default configuration, and I don't want to hard-code the .app filename in (although it'll be something like build/<config>iphoneos/<name>.app). Currently, I'm parsing the output from the xcodebuild command and grabbing the line
CodeSign (.*)
which works correctly, but seems like an awfully roundabout way of doing it. Is there another command line tool to do this, or at least an easier way than my solution?
Tough to say since the build location can be project/target specific or a global preference that's never explicitly set anywhere in the project file.
Never tried it, but maybe add a Run Script build phase to your project that simply prints the environment to stdout and parse that?
I want to include the Application Loader process in a software installation, to ensure that users get our software installed on their Blackberry by the time our installer software finishes.
I know this is possible, because Aerize Card Loader (http://aerize.com/blackberry/software/loader/) does this. When you install their software, if your Blackberry is connected the Application Loader will come up and force the .COD file to install to the device.
I can't make it work. Looking at RIM's own documentation, I need to:
Place the ALX and COD files into a subfolder here: C:\Program Files\Common Files\Research In Motion\Shared\Applications\
Add a path to the ALX file in HKCU\Software\Research In Motion\Blackberry\Loader\Packages
Index the application, by executing this at the command line: loader.exe /index
Start the force load, by doing this: loader.exe /defaultUSB /forceload
When I execute that last command, the Application Loader comes up and says that all applications are up to date and nothing needs to be done.
If I execute loader.exe by double-clicking on it (or typing in the command with no parameters), I get the regular Application Loader wizard. It shows my program as listed, but un-checked. If I check it and click next, it will install to the Blackberry. (This is the part that I want to avoid, and that Aerize Card Loader's install process avoids.)
What am I missing? It appears that the Aerize installer is doing something different but I haven't been able to ascertain what.
You can do it easily with the following command:
C:\RIM\JDE_4.7.0\bin\JavaLoader.exe -u load <.cod file>
With this command you don't need an alx at all, just the cod file. Look at JavaLoader usage help to see full options.
JavaLoader.exe can upload one code file. What about two or more cod files?
