I can't get the controller emulator to work with Google VR SDK 1.1 & Unity 5.6b3 under Arch Linux 64-bit. If I load the GVRDemo scene in Unit and click the play button to enter Play Mode, the console shows the following:
"Android Debug Bridge (adb) command not found.
Verify that the Android SDK is installed and that the directory containing adb is included in your PATH environment variable."
In Windows, you have to add the directory containing the Android Debug Bridge (adb) program to the PATH environment variable in Windows itself (not in the Unity program). Once you do that, the Controller Emulator works fine in Windows. You have to do the same in Linux, evidently, to get Unity to locate adb, and therefore get the Controller Emulator phone working for testing the game.
I've added the following line in my .bashrc and .profile files in my home directory:
"PATH=/home/jesse/Android/Sdk/platform-tools/:$PATH"
This, however, doesn't fix the issue.
I've also added the root directory of the Android SDK to my Unity Preferences > External Tools section.
I don't know how to get Unity and Google VR SDK to recognize the directory containing adb to the PATH environment variable that Unity needs to make the Controller Emulator work.
Is anyone else having this issue? Is there a fix or work-around?
I was able to locate the culprit and modify Google VR SDK scripts to make it work! Turns out there was an issue in the code of the script file titled "EmulatorClientSocket.cs" regarding non-Windows machines. Here's what I changed, and why:
Originally, in line 111 and 112 of this script, it read:
stringprocessFilename="bash";
stringprocessArguments = string.Format(" -l -c \"{0}\"", adbCommand);
The context is that when Windows is not present (forgive my layman's terms -- I've only started learning coding a month ago) the command to process is this: bash -l -c "adb forward tcp:7003 tcp:7003". The problem is when the -l option is used in the command, the command is interpreted as if coming from a login shell, which - I believe - means that bash isn't looking at the custom environment variables set in the user's .bashrc and .profile files in their home directory. Without looking at those files, bash can't locate the adb command (try running the bold command above in a terminal, and the result will be a prompt saying adb command not found).
To fix it, I simply removed the -l option from line 112, and, voila! Everything works like a charm! Lines 111 and 112 now look like this:
stringprocessFilename="bash";
stringprocessArguments = string.Format(" -c \"{0}\"", adbCommand);
The fix will work when running "unity-editor" or "unity-editor-beta" from the Terminal or Xterm, but running it from the application menu will still produce the adb error and Controller Emulator will not work.
Trying to run my web2py app from the development server using GoogleAppEngineLauncher
Not sure if the on-line tutorials are out of date or I'm just missing something, but when I follow the link to download the GoogleAppEngine pythonSDK for OSX I get a dmg for the GoogleAppEngineLauncher.
I download and use that, which installs the proper executables, however after I setup my app.yaml file and run "dev_appserver.py myApp" I get this error:
fancy_urllib.InvalidCertificateException: Host appengine.google.com returned an invalid certificate (_ssl.c:503: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed):
I don't get the error if I try and launch the app from the launcher itself, however I can't launch the app because it says the directory already exists and I don't have write permissions. I even tried chmod 777 on the myApp directory.
Should I not be using the GoogleAppLauncher?
additionally I tried using the linux SDX and received the same "certificate" error. The error message directs me to a link mentioning that I need the "ssl" module, but that is included in python 2.7.2 which I am using.
The link also mentions: "appcfg uses SSL when connecting to the Admin Console by default, unless the --insecure flag is passed." But I cannot find that flag in the help menu.
Found this answer which solves the problem.
Basically:
rm google_appengine/lib/cacerts/cacerts.txt
From the SDK
I am using the maven gae plugin for my build and deploy of google appengine app (under windows). All works as expected.
However - I notice its also possible to download the GAE with the same pluggin. It looks to me like something like:
mvn -DoutputFile=./test.log gae:logs
should work - however it just gets stuck at:
0% Beginning to retrieve log records...
and goes no further - what am I doing wrong?
Using
mvn -e
or
mvn -X
don't seem to provide any helpful output
I tried an absolute path as well on OSX and it refuses to honor the -DoutputFile argument and puts the logs in target/gae.log no matter where I try and tell it to put it or name it instead.
So go look in your project_dir/target/gae.log file
I have GWT app, which is deployed on GAE (Java). I'm trying to download data from App Engine datastore using appcfg.py . I did all the setup according to http://ikaisays.com/2010/06/10/using-the-bulkloader-with-java-app-engine/ .
GAE Python SDK version is 1.4.3
Python version is 2.5.4
appcfg.py is on my PATH. When I run appcfg.py on the command-line, I get the "help" message. But the problem is that no matter which command I use, it always returns the help message. I have not been able to run any command using appcfg.py.
It doesn't give any specific error message no matter what arguments I give. My app is using Google Accounts authentication, but I don't think it even gets to the point of authentication.
I'm able to use the Java appcfg (for other actions like rollback) without any problem. But the Python version simply refuses to work for all commands.
I've tried different formats like:
appcfg.py create_bulkloader_config --url=http://myappid.appspot.com/remote_api --application=myappid --filename=config.yml
appcfg.py create_bulkloader_config --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api
appcfg.py --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api create_bulkloader_config
All give me the same help message:
Usage: appcfg.py [options]
Action must be one of:
create_bulkloader_config: Create a bulkloader.yaml from a running application.
cron_info: Display information about cron jobs.
download_app: Download a previously-uploaded app.
download_data: Download entities from datastore.
help: Print help for a specific action.
request_logs: Write request logs in Apache common log format.
rollback: Rollback an in-progress update.
set_default_version: Set the default (serving) version.
update: Create or update an app version.
update_cron: Update application cron definitions.
update_dos: Update application dos definitions.
update_indexes: Update application indexes.
update_queues: Update application task queue definitions.
upload_data: Upload data records to datastore.
vacuum_indexes: Delete unused indexes from application.
Use 'help <action>' for a detailed description.
Options:
-h, --help Show the help message and exit.
-q, --quiet Print errors only.
-v, --verbose Print info level logs.
--noisy Print all logs.
-s SERVER, --server=SERVER
...
...
...
Even when I try "appcfg.py help create_bulkloader_config" for a detailed description, it still shows me the same standard help.
I have also tried on the local development server using the url http://127.0.0.1:8888/remote_api but it still gives the same help message.
I'm totally clueless as to what the problem is. I'm new to GWT and GAE, and any help will be appreciated.
Thanks.
The following fix worked for me. It looks like appcfg.py doesn't like PYTHON27 and ALWAYS returns the help menu. I fixed it by executing it with PYTHON25 and hard coded all my file locations:
C:\Python25-archive\python "C:\Program Files (x86)\Google\google_appengine\appcfg.py" rollback C:\scripts\myapp
The right way is to change the environment variables on Windows 7:
Go to System Properties
Go to Advance System Settings
Click on Environment Variables
Append to Path variable the values C:\Python27\
Click Ok and restart your computer. (Yes, it is needed.)
Another way is to:
Open command Prompt
Locate your python.exe file. For example:
C:\Python27>_
Then, run a python command that looks like this.
python <appcfg_directory> download_app -A <your_app_id> -V <your_app_version> <output-dir>
Where <appcfg_directory> is equal to C:\Program Files\Google\google_appengine\appcfg.py. (Depending on your file location)
Don't forget to put quotes before and after <appcfg_directory>
This seems like it should be very easy but I don't see a link to it anywhere.
How do I download the source code of a google app engine project?
Windows
appengine-java-sdk\bin\appcfg.cmd -A <your_app_id> -V <your_app_version> download_app <output-dir>
Linux
./appengine-java-sdk/bin/appcfg.sh -A <your_app_id> -V <your_app_version> download_app <output-dir>
For completeness, using the Python implementation:
appcfg.py download_app -A $appID -V $appVersionNumber $downloadDirectory --oauth2
--oauth2 is of course optional, you can omit it and provide your email + app-specific password (or your password, and then go implement two-factor authentication right after), but it's easier, and frankly there's no reason not to.
Documentation.
App Engine actually recently added the ability for the developer who uploaded a given app version to download its source code.
As of October 2019 you can simply go to --> App Engine --> Services and in the tool dropdown select 'source' and the source code is there
Posting this since none of the listed methods above didn't take me to the code (by June 2021)
You could try accessing it through;
Google Cloud Platform > Debugger > choosing the version of the
Application from combo at top.
This will list the files of that version on the left pane. There is no way to download it automatically but you can copy-paste the code.
Hope you will find this helpful.
IMHO, the best option today (Aug 2018) is:
Under the main menu, under Products, go to Tools -> Cloud Build -> Build history.
There, click the ID of the build you want (for me - the last one).
Then, in the opened window (Build details), click the "source" link, the download of your compressed code begins.
As simple as that.
HTH.
Working with App engine standard using Go, the debugger isn't available yet.
How I managed to download the source code for an existing service was to use the gcloud tool.
First: Get the version id of your service using the app engine console or running: gcloud app versions list
Second: use the version and service name and run: gcloud app versions describe <versionID> --service=<service name>
the describe parameter will give you the storage locations for your source files that looks like this:
cmd/main.go:
sha1Sum: e3fe5848c2640eca7ac3591490e1debc2d3a9b09
sourceUrl: https://storage.googleapis.com/<project>/<file id>
Third: you can then use the storage console, using the file id, to download the files you are interested in.
this process based on java sdk
Its works for me...
Download Google cloud SDK
gcloud init
enter image description here
Follow through process of logging in using your credentials
Enter following command from SDK
C:\Program Files (x86)\Google\appengine-java-sdk-1.9.49\bin
enter image description here
Enter Following command to download source code
appcfg.sh -A [YOUR_APP_ID] -V [YOUR_APP_VERSION] download_app [OUTPUT_DIR]
Eg: appcfg.sh -A my-project-name-1234 -V 2 download_app C:\Users\india\Desktop\my project
Note: this progress based on java-appengine sdk so we use appcfg.sh instead of appcfg.py
check if your app is uploaded with same email id that is in your app engine. if you are not sure then in app engine > control > Clear deployment credentials and then click on any project, deploy to sign in again then use this
appcfg.py download_app -A {app id from google app engine} -V {1} "{c:\path}" --oauth2_credential_file=C:\Users\{your account name}/.appcfg_oauth2_tokens
change all {} to your needs
Things have changed since this question was asked so I'm adding an updated answer. Note that this only applies to GAE Standard Environment
Google has deprecated appcfg.py and so the previous responses appcfg.py download_app no longer works.
gcloud which is the SDK in use (it replaced appcfg) does not have the functionality to download your source code.
When you deploy your app via gcloud app deploy, it copies your source code to a bucket. The default bucket is staging.<project_name>.appspot.com. Your files will stay in this bucket for a maximum of 15 days before they are deleted. You can modify the rule so that the files are retained for longer or less time.
The file names in the bucket are encoded so you can't figure out what each file is unless you open it (i.e. download it). Google has a mapping of the encoded names to the original file names. To get this mapping, you run the gcloud app versions describe command and it will list the file names and their encoded names. To download the files, you have to manually click each url one by one. So essentially, you have to download each file manually and then use the mapping to rename them (or open the file, check the content and then rename them). Also note that downloading the files manually will not maintain the folder structure in which they were uploaded.
If you do not wish to go through all of the above hassles (imagine having to manually open each url for each file if you have a small to mid-sized project which has hundreds of files), our App - https://nocommandline.com - now supports downloading source code from the default bucket - staging.<project_name>.appspot.com (so far as your files are still there which means any deployment i.e update not older than 15 days from your current date unless you previously increased the deletion age on your staging bucket's lifecycle page).
In simple terms, you enter your project name, the version number and our App will take care of retrieving the original file name to encoded name mapping, automatically downloading the files and renaming them to the original names, while maintaining the folder structure. For more information, refer to https://nocommandline.com/help/#faq_download_source_code_from_gae.
Log in to the console.developers.google.com
Select the project you want to download the code from (Google App Engine Standard Envoronment).
Go to the App Engine Dashboard. Under Summary is Debug and Source. Click on Source.
Select each file one at a time and copy it (highlight the code, copy and paste into your local editor.)
Select the next file....
You need to use svn to checkout the files.
If you are on Windows, you can use tortoise svn for your GUI end.
Here are tutorials on how to do it, here is the related question.
