I'm trying to install android studio, but while I was installing it I got this exception:
My question is what is the Android Emulator Hypervisor? what does it do or enable me to do? I tried looking it up online but I kept getting into these rabbit holes of information that kept expanding and expanding. I just want a concise answer for my small brain and maybe a quick and clear explanation to fix this.
The emulator essentially creates virtual machines running specific Android versions in order to run your apps. The Hypervisor driver is something that can help a lot with performance. If you want to check out the details, this documentation page might be a good start.
To fix your installation issue you only need to follow the link given in your error message, there's not much need to understand hypervisor workings.

I'm having trouble with my android studio and I even changed my windows, now I'm just frustrated. Can someone help me? I almost looked everywhere.
So this is when I've installed android studio and this appears.
Then it automatically goes to this page and wants to download android SDK but the check box is not activated! and as you can see the download size is 0!
And that's the next one!
So I quitted the setup and opened the SDK manager from the android studio and this is what it says:

does anyone know what should I do to download SDK? And by the way, I'm living in Iran, that's one of those countries that include United States sanctions. Do you think it's related and if Yes what should I do?
p.s: This is the first time I'm asking a question on Stackoverflow, so forgive me if I did something wrong in the asking process.
After doing some changes to my IP I could fix the problem. So, if anyone has the same problem I think it's related to their countries limit problems. You should change your IP.
I am trying to leverage my very modest Ruby experience with Ruboto. I have installed the necessary packages, and the various demos work well on the simulator (on Windows) and on my Android device. I have been able to write some very simple Ruby scripts for Ruboto, but when they don't work, I have no visibility over what is happening. The only error message I get is: "Unfortunately, xyz has stopped."
I assume there must be a way to troubleshoot a Ruboto script and get a log or some kind of detailed information on the reaction of the system to each line of code.
I have been googling that question for a while without success, and I apologize if I missed something obvious. I also tried "adb catlog" without getting any useful information related to the Ruby script, but maybe I was not able to find the right information in the thousands of line generated by this command.
I hope someone can point me in the right direction.
Thanks
At the moment, the debugging options for Ruboto are limited and low-tech.
You can analyse the log using "adb logcat" or the newer "rake log". "rake log" uses "adb logcat" but applies a filter so you get much less noise. If your app crashes, you should see a Ruby stack trace with the immediate cause of the crash. This is probably what most Ruboto developers use now.
Another option is to encapsulate a risky method with a "rescue" that either logs a better message, or displays the error in a dialog. This would probably be more helpful, but requires a bit more work. You could request this as a Ruboto feature in the Ruboto issue tracker :)
Would something like "debugger" work here?
It would be awesome if it could...
I have used this site to help me with the apkTool in the past, however I have today come up against an error I can't quite get my head around.
I am DE-compiling an APK which was written by a predecessor as it requires a few tweaks and he hasn't left any source files behind..
So, As far as I'm aware I have the latest tool available, using windows 7 64bit.
I have added the framework from my test tablet which the app runs fine on. And this is what I get..
This is the error screen

Anyone have an idea at what the issue is here? Any help really appreciated.
There's an open issue on a similar exception (scroll to the bottom):

few days ago, when I was debugging an Android project under eclipse I've found some great functionality: "All instances..." and "Instance count". I wanted to share my findings with rest of my colleagues, but none of them had this functionality in their eclipse install (we all use eclipse 3.7).
What's even more weird now I'm also missing this functionality.
As far as I can tell this functionality is build within eclipse from version 3.3 and available to projects using Java 1.6 and above as mentioned here and here (we're using 1.6).
See bottom of this link to see what functionality I'm talking about. It even has it's own shortcut in options (ctrl+shift+n) so I think there must be a way to use it again.
I was looking for it while debugging and while the debugger was in "stopped" state.
Anyone can help me put eclipse in right view/perspective/state to see this functionality again?
EDIT
Here is the documentation entry from eclipse help page: link
Thanks for any suggestions,

After some more digging I came to following conclusion:
DalvikVM does not support "instance retrieval".
On eclipse help page mentioned in EDIT section it written:
This command is only available if the Java virtual machine you are currently using supports instance retrieval.
Maybe there is an option to enable this option in DalvikVM, but I doubt it unfortunately.
Also when debugging on phone "Drop to frame" functionality is missing.
I recently started messing with Android Apps, but I have had nothing but problems trying to get them into the Virtual Device for testing. For some reason, they never seem to show up in the AVD. It has worked one time, but that's it out of hours spent just trying to test one or two very simple apps.
I've redone the AVD setup many, many times, trying different settings and what not to no avail. I've followed multiple guides and tutorials to the letter to get it working, but they just refuse to show up in the list. :(
Any insight would be appreciated, thank you.
I would start by testing apps that are known to work. Here are sixty or so of them.
In particular, I would start with this one. Do not change anything. Do not import it into Eclipse. Just install Apache Ant (if you haven't already), and run ant install in the project directory with your emulator running.
Either this shows up in your emulator, or it does not.
If it does not, try reinstalling the entire SDK.
If it does, then you know that your base environment is OK, and you can start slowly determining the differences to figure out where things are going wrong.
Helping you is difficult right now because your symptoms are a bit generic. It could be that you are using Eclipse and Eclipse is having a problem. It could be that your adb daemon is having a problem. It could be that you don't have any activities in your manifest, so the application is actually installing but there are no icons in the launcher. And so on.
