When I open a project in the android studio (latest version), it gives the following error:
ERROR: Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used. Please refer to the
user guide chapter on the daemon at
https://docs.gradle.org/4.1/userguide/gradle_daemon.html
Please read the following process output to find out more:
Error occurred during initialization of VM
Could not reserve enough space for 1572864KB object heap
Yes, I know that it is saying that there not enough Memory to run the Daemon Process as I have only 3GB RAM. So what is the alternative for it?
Is there any issue if I'll not start the daemon process? As Only Android Studio consumes 800MB
modify value of below mentioned variable in 'gradle.properties' in root of your project.
org.gradle.jvmargs=-Xmx1536m
change it to 'org.gradle.jvmargs=-Xmx536m' and restart android studio.

Check the JVM arguments defined for the gradle process in:
- gradle.properties in project root directory
As far as i can see i need more memory but i have 16gb ram and android studio is already using 12gb.
JVM uses something called a heap to decide how much memory it is going to take while it performs the necessary tasks. You can consider it something like a place for keeping user defined datatypes at runtime.It is similar to RAM but not quite
Two solutions
You can manage your heap space for larger projects using this gui based way
If you prefer the non gui way,which is always more reliable, this is a sample gradle.properties file I am attaching from one of my projects
Note that the 1024m specifies the amount of RAM to be be given to JVM for the heap storage(1024MB). You can double it in your case, i.e . 2048M or even triple it

I have recently upgraded my RAM from 2GB to 4GB, I tried to re-install Android studio in my machine through the Ubuntu shell and an this error in the below image:
Is there anyone ever encounter this error before? If there is any useful resource, please share with me to solve this issue.
I ran into this issue too after I haphazardly edited my VM options from within Android Studio without really paying attention to what I was copy-pasting off StackOverflow. In my case the error was this:
Invalid maximum heap size: -Xmx4096m # <------ increase this to most of your RAM
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
My machine has 8GB of RAM, so this helpful error message is instructing me to set this to a higher value.
In your case, -XmxheapSize is clearly not a valid value.
On Ubuntu I had to edit the offending line in this file:
~/.AndroidStudio3.1/config/studio64.vmoptions
(folder and filename may be different for you depending on which version of Android Studio you have and whether you're using 64 or 32bit.)
Run ls -a in your home folder to see all hidden folders, if you're not sure what your Android Studio config folder is named. See this for more details.
i cant fix this error
Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.

Invalid maximum heap size: -Xmx256ml
Open gradle.properties in root of android project and check what all lines are commented out. I think, this problem occurs when you don't have enough RAM.
Looks like your vmoptions file is somehow corrupted.
If you can start Studio, then you can edit these settings from the Android Studio menu. Open Help->Edit Custom VM Options. Check to make sure the -Xmx line has something like -Xmx256m. The error line you posted above seems to indicate that there is somehow an extra l at the end of the line. If there is, remove just the l, save and restart.
If you can't start Studio, then you need to manually edit studio.vmoptions or studio64.vmoptions, depending on your installation. These files are located a local preferences directory with a name dependent on the version you are running. See this for the different possibilities. For me (64-bit Ubuntu 16.04, Studio 2.1), studio64.vmoptions is located in ~/.AndroidStudio2.1. Do not edit the vmoptions file in the installation directory (unless of course this is where the problem was introduced).
I'm trying to create a simple (software) driver using these instructions.
Host is Windows 7 x64 with fully updated MSVS Express 2013.
Latest windows driver kit is installed and working fine.
A virtual machine also with Windows 7 x64 is succesfully provisioned by VS, and configured exactly following these instructions.
The deployment process seems to execute properly and the build log shows something like:
1> Catalog generation complete.
1> <snip>\Win7Debug\Driver Package\driver.cat
1> Done Adding Additional Store
1> Successfully signed: <snip>\Win7Debug\Driver Package\driver.cat

However, when Visual Studio tries to start a debug session, I receive the following error message:
Unfortunately, there's no mention of which file it can't find. I've tried attaching a debugger and hooking kernel32's MessageBox so that maybe I could check the call trace / see which file it is looking for, but VS doesn't like me attaching ollydbg and it brings up a whole lot of other issues.
I've also tried Process Monitor to see what file it is trying to access but it's pretty hard to wade through everything it is doing.
Am I missing something? Anyone can point me in the right direction?
edit1: Did a clean install of both the host as target machine. Followed instructions perfectly: exact same error. Has nobody come across this before?
So the answer is that Visual Studio defaults to Kernel Debugger rather than Remote Debugger. Changing this at least got it to deploy and install the driver, but still caused the build process to hang forever.
I've given up on trying to write a KMDF driver and will instead opt for a global hook via SetWindowsHookEx instead. Not something I preferred, but the process for writing a kernel mode driver in Windows is way too tedious in my eyes.
I have installed java and tomcat appache server on linux.
When i am going to start tomcat using ./startup.sh command on linux server,
it gives output as
Using CATALINA_BASE: /usr/src/apache-tomcat-5.5.28
Using CATALINA_HOME: /usr/src/apache-tomcat-5.5.28
Using CATALINA_TMPDIR: /usr/src/apache-tomcat-5.5.28/temp
Using JRE_HOME: /usr/src/jdk1.6.0_16
Using CLASSPATH: /usr/src/apache-tomcat-5.5.28/bin/bootstrap.jar
but server is not started.
after that when i am firing javac command ,it generates following error
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
i am not getting the right reason for that.
I am new with linux.
Please help me.
Thanks in advance
Could not reserve enough space for object heap.
Looks like there is not enough memory given for the initialisation.
Check the given memory...and reconfigure your memory size for the JVM.
