I am having some difficulties setting up the virtual (emulated) sdcard in Eclipse. The target API is 2.3.3 (Gingerbread).
I have read and followed this article (Referred to me by a member here).
This is where the problems start - I have already made a sdcard.img file in setting up my AVD emulation. Ihave also put in the correct file path as per step 2 (and double and triple checked the file path was correct).
The problem is when I go to the DDMS --> File Explorer, it is blank, as in totally blank - no files whatsoever are showing.
I have tried recreating the AVD emulated device, and have restarted Eclipse after each step to no avail. Possibly a silly question (remember, this is new to me), but even though I have specified the parameters for the SD card when setting up in the AVD manager, do I still need to do step 1 (of the link above)?
You need to click on your emulator name in the "Devices" tab. That will refresh connections in the "File Explorer" tab with your emulated device. If you don't see your emulator in the "Devices" window, then reset adb.

Is there a way to give an emulator a name in Android Studio?
In the emulator pull-down box in Android Studio, the emulators created from AVD manager are labelled simply: "Android SDK built for x86 (mobile)(emulator-nnnn)", where n is an integer.
If you're running multiple emulators, this isn't very helpful. Is there a way to rename each emulator to something more helpful? For example, when I created each emulator, they have names of e.g. "Pixel 4 API 29", and "Nexus 5 API 24" - why aren't these used?
Update: Two screenshots show what I mean. In the top one, the "Nexus 5 API" has been selected; yet it shows as "Android SDK etc". If I select e.g. "Pixel 4 etc", it shows as exactly the same (it actually has an emulator number added that only shows when you open the pull-down).
Of course you can edit the name of your AVD.
In the AVD Manager, clic on the pen to the right to edit your configuration and then, you can rename your AVD
Edit: There names are correctly shown in the pull-down menu, even if launched
Well what #Bruno said is the easiest way, if it does not work that way you can either try this one, is a little bit tricky though.
In case you use Mac that's an example of how to do it, if you do not use Mac let me know and I'll put the steps to do it on Windows / Linux
Open in Finder
user.name/.android/avd/
Pd: To be able to show the hidden files press ⌘ + ⇧ + .
Find your emulator, in my case I'll show this one :
Open the Pixel_4_API_30_-_Android_11.avd folder (in your case will be different) and open config.ini file and change these two params (AvdId,avd.ini.displayname)
And now restart your IDE and it should be updated.
I'm sure you could change more names, but to ensure the functionality of the emulator, I wouldn't touch too much if you do not know what you are changing.
Let me know if it works :)
You can not change the device name "emulator-nnnn" from Android Studio as that name belongs to the device. This is the name that you see in "adb devices" output.
For a real device, you have to change its name by opening the Settings app from the device.
For an emulator, in theory you can do the same, you open the Settings app inside the emulator when emulator is running. But I haven't tested this because my emulator is very slow.
I'm not able to change the ram size in the memory and storage section of the AVD manager in the android studio. I wanted the emulator to run a little faster (I have 8GB RAM). The controls are completely gray out.
If you create an AVD with "Recommended" system image then you can't change the "Memory and Storage" parameters neither when you create AVD nor when you edit your AVD.
Solution:
You should select your "Image" from "x86 Images" tab and then change "Memory and Storage" parameters in the next page.
It happened to me with an image with the pre-installed playstore app. Maybe it is an android SDK bug. Try to create one with no playstore app.
Look for your avd folder, then look for the folder of the image you want to change and edit the config.ini.
change the value of
hw.ramSize
Here is a solution for Android 4.1 that worked for me.
Create AVD as usual over AVD Manager
Open location on the disk where AVD data is saved
open the config file that is there over the notepad. Inside should be a line that starts with the hw.ramSize line. There you should change the number of MB you want. Save changes, close file.
In Android Studio click File > Reload All from Disk
If you select View Details you should see there that ram size is changed now.
I hope it will help.
You can do so by editing the config.ini file of the int the avd settings look for this
>hw.ramSize
Editing is disabled,but you can create a new virtual device by using Clone Device.. option.Once installation of OS is complete, edit the RAM again in Advanced Settings before clicking Finish.
Further adding to the answer by Fresher, it seems that even x86 images don't work(atleast its the case with my mac OS).
Here is the screenshot:
Advanced Settings:
What worked for me:
I just used "Clone Device" in Hardware selection wizard(the first one that opens after you click on the "AVD manager"
Then setup your ram here:
Once you hit "Finish", you will see your cloned device appear in the hardware selection wizard like this:
Then go ahead as usual.
just get the emulator whith api which has no google play from x86 images,just set your ram size, then change image to the api which has google play it has worked for me
creating
changing ram size
changing android image
selecting android image
It has worked and I have play market
Since Android Emulator 2.0 this should be supported:
Drag & Drop
With the new emulator, you can not only drag and drop APKs for quick installation, but you can also drag and drop any file to your emulator’s internal SD card to help in testing. link
I have the following problem. When I drop something (like pdf, image or apk) to the emulator at my workplace it won´t work, the mouse icon changes see screenshot.
It also won´t work for my colleague. But at home at my personal computer it works like charm.
I already changed the avd, to phone, another apk level, with devices frame, nothing works.
Drag and drop in gernal works on my pc though, if I drag something into chrome (pdf) it will open it as intented.
Please check path of Android Emulator (from Xamarin or another). I think it must be string like C:\Program Files (x86)\Android\android-sdk in Visual Studio:
Tools -> Options -> Xamarin -> Android Settings -> Android SDK Location and change it. Remember to run Visual Studio as administrator.
The next thing is to check paths in register. Press the Windows key and R, enter regedit.exe then find path HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools. Next, check it the value(string) of Path.
Secondly, please repeat for this path HKEY_LOCAL_MACHINE\SOFTWARE\Android Studio and compare current path value to previous value.
I hope this help at the beginning.
I think I have installed all the system images required for android m preview, but still my emulator is showing nothing, its always blank. Please help me
After Suggestion i have downloaded the other requirements, but still its not working
You have sufficient files to create the emulator might be you are editing the existing emulator, i suggest try to create a new emulator, and try to keep the Ram consumption lower to get better performance.
Refer from the above link you can create your new emulator by following below steps
Step-1: Go to Android SDK folder and run AVD Manager. Click on Create
Note: Use default value for Max VM application heap. As Android supports variety of displays, you can explore with different devices by selecting in Device: dropdown
Step-2: Select the virtual device which you just now created and click Start
Step-3: Do not make any change under Launch Options and click on Launch button
Step-4: Emulator will start a few Command Prompt windows flicker. You should now see the following screen, with the Android device booting up, which will take about five minutes
Step-5: You should now see a screen saying Emulator has been successfully installed
Your Windows/Mac PC should now be ready to get started with the Developer Preview.
Go to Android SDK manager you need to download the Android m preview section.Then follow these steps
Step 1: Run AVD Manager and click on Create.
Note : Select a small resolution screen if your RAM is low.It will be a plus in case of performance part.
Step 2:Enter the Ram value to 1Gb if your system(Computer)RAM is about 4gb or RAM value as 2gb your system(Computer)RAM is about 6gb or 8gb.
Step 3:Select the device which you created now, press Start and select Launch Button.
Step 4:You should get a alert box showing that Successfully installed.
Step 5:An android device with android device booting up screen will be appeared and it will take time depending upon the RAM you allocated at the time of creating the Android Device in AVD.
NOTEmake sure not to run too many another programs while you trying to launch or using the emulator.(make sure the IDE is uptodate)
Happy Android M Preview....
If you want to create MNC(Android M Preview) emulators, you could follow these steps:
1, Of course, downloads MNC System images. Open SDK Manager, select images like Android TV Intel x86 Atom System Image, ARM 64 v8a System Image, ARM EABI v7a System Image and something like that.
2, open AVD Manager by clicking the button on the top of Android Studio. Then you will see "Your Virtual Devices" window.
3, Click the button of "Create Virtual Device" at the left bottom of the window. Then you will see "Select Hardware" window.
4, then select the category and name of the emulator you want, and then "Next".
5, if you have succeeded downloading MNC System Images, you will see them from the "API Level"
6, and then click "Next", you will see "Android Virtual Device(AVD)" window, you can change settings if you want to.
7, click "Finish" and wait, util emulators are prepared.
I had the same problem,
I copied the system image from the default directory:
C:\Users\eli\Downloads\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk\system-images\android-MNC\default\arm64-v8a
to the image root dir:
C:\Users\eli\Downloads\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\sdk\system-images\android-MNC\arm64-v8a
I restarted eclise, and now, I could see the android M and the arm64 system image.
'qemu: could not open disk image C:\Users\William.android\avd\Nexus_5_API_21_x86.avd\sdcard.img: Operation not permitted
Error accepting connection, aborting'
how do i fix it? bear in mind i'm an ultimate beginner
I hade the same problem. I solved it by going to the AVD Manager and removing the virtual device and then add a new virtual device.
I'm Using Android studio IDE and I always face to such problems. For dealing with this matter, one approach is to :
Tools > AVD Manager > Run your Virtual Device
Run your program while your Virtual Device is completely loaded.
This solution works for me. Hopefully it works for you too.
This happens when you try to run two emulators at the same time and both use the same sdcard image file (sdcard.img).
Most likely you have duplicated an AVD definition that used this sdcard file and the original AVD instance was already running when you launched the clone.
The solution is to edit the newly created AVD definition, go to "Show advanced settings" -> "Memory and storage" -> "SDCard" and point to another image file or select "Studio managed".
