Unable to generate cloud end point client library - android

I'm building an app that uses GAE using this tutorial and I'm trying to generate a Cloud end point library for a class as explained here.
However, I'm getting an unexpected error. Here are the details:

Eclipse version I'm using is 4.3.

I am facing the same problem. But, I have found this link and I think it can help:
http://mall.51zks.com/Problem/index/-190279264/generating-the-api-metadata-for-cloud-endpoints-classes-failed/
It basically links forward to this link, which tells how to create the endpoint library using command line too:
https://developers.google.com/appengine/docs/java/endpoints/endpoints_tool
I am working on this solution now. If I get any good news, I will update.

As described in Google bugtracker this is a known bug, you must either downgrade to 1.9.3 or upgrade plugin tools to 3.6.0
see: https://code.google.com/p/google-plugin-for-eclipse/issues/detail?id=278

Cannot build empty flutter project with intellij or android studio

I have been coding kotlin in intellij to develop an app for android but then found out about flutter and wanted to give it a try. Installed flutter sdk and flutter and dart plugins ok. Now even the default empty demo project runs in both my phone and in emulator but i can't build it and cannot generate an apk. I have also downloaded the android studio to try with it but a similar error occurs in it too.
Searched all the web for a solution.

Android Studio 3.0 rc2: Android Device Monitor failed to open

I've recently updated my Android Studio to 3.0 rc2 using Beta channel of the update section inside the application.
Today I wanted to use Android Device Monitor where an exception happened and saved to log inside sdk folder.
The log is this:

I don't know how to handle this error and I need a way around.
I'll be glad with any suggestion to solve it without mentioning "download stable version" and downgrade.
UPDATE: After I tried to update to Stable version through the Stable channel of update section I get error that some files missing
gradle/m2repository/com/android/java/
gradle/m2repository/com/android/java/tools/
gradle/m2repository/com/android/java/tools/build/
gradle/m2repository/com/android/java/tools/build/java-lib-model-builder/
gradle/m2repository/com/android/java/tools/build/java-lib-model/
I'm trying to update every single module so maybe I could solve this issue
UPDATE-2: After cancelling previous error and running the Android Studio, It seems to be updated but the error is still there, here is the error after updating to Stable version:

UPDATE-3: After A LOT of searching, I found a solution but it's not the answer so I added this update to question.
I can run the Android device monitor manually by going to /sdk/tools/ and run the monitor.bat file by cmd or powershell and now I have access to this feature, but even now, the Android Studio can't open it for me!!!!
Please if anyone can help me post an answer telling me a workaround this problem.
After a lot of try and catch! I finally fixed the issue.
Android Studio 3.0 is not fully support JDK 9
After installing JDK 8 on my system and set it as JAVA_HOME variable and restarting the system everything is working now.
I got it because I wanted to install Nativescript and I couldn't cause it only supports JDK 8. that was my first clue
Set JAVA_HOME variable to JDK 8 directory and everything will be okay
If you are on windows try opening your Android Studio in Administrative Mode (Run as administrator)

Android-Studio won't start, NoClassDefFoundError com/intellij/openapi/diagnostic/Logger

I'm trying to run Android-Studio on a Debian Jessie machine, but it won't.
Just unpacked it, marked bin/studio.sh as executable and executed it.

No log is written or anything else. Already searched and tried various things (e.g. adding lib/openapi.jar manually to the classpath, etc) for more than an hour, but it is still not working
Please ensure that there are no spaces in the path where Android Studio is installed.

RemoteWebDriver+AndroidDriver : error communicating with browser

I've recently started working with -> RemoteWebDriver+AndroidDriver . I've started with a basic example as follows:
stmt1:WebDriver driver=new AndroidDriver();
stmt2:driver.get("http://www.google.com");
stmt3:WebElement element = driver.findElement(By.name("q"));
stmt4:element.sendKeys("Cheese!");
'stmt1','stmt2' opens google.com successfully on the emulator .
The issue is that 'stmt3' & 'stmt4' don't work .Emulator closes webdriver and following exception is generated in eclipse :
org.openqa.selenium.WebDriverException: Error communicating with the remote browser. It may have died.

From the stacktrace, it seems your selenium version is 2.12.0. The current version is 2.25.0. Probably using latest could solve the problem.
Problem was that I used android 2.3.3 (bug on Gingerbread might have caused WebDriver to crash). On upgrading to android 4.0.3 the code runs fine.

I'm running snow leopard and have jre (or jdk?) 1.6.
Any ideas how to get this working? Thanks!
I have found a solution(Ubuntu 10.10, java-6-sun). Copy swing-worker.jar into /path_to_android_sdk/tools/lib. You can find swing-worker-1.1.jar in the same directory in SDK r7 or download it from here.
