I had this problem on Android L developer preview  and  at least for this version  I solved it by creating an sdcard with a size that had square 2 size  e g 128M  256M etc

I guess  you didn t insert memory size at the time of creating avd  you can do that by editing the avd

Android studio version 0 8 9 and above has a bug creating AVDs   See Issue 78434   Workaround   go to your ADV folder in  android folder and find your AVD config ini open it with a text editor that can handle unix newlines   Notepad will run the lines together since they don t have CR-LFs   change hw sdCard no to hw sdCard yes   this should work for everyone in new builds

Maybe it sounds stupid but it worked for me when I had the same problem  delete the created avd and create one again through AVD Manager with a sd card of  for example  512MB   Check that both have the correct permissions and if not  try to change them with chmod   And if everything still fails  repeat the process but creating both avd and sd card manually via terminal   android create avd -n my avd -t 7 mksdcard -l e 512M mysdcard img emulator -avd my avd -sdcard mysdcard img   Hope that helps

Ensure two things in the AVD manager utility for the emulator    SD Card size is mentioned e g  512  From the Hardware tag  press New and select  SD Card Support  from the drop down menu    Now  start the emulator  SD Card shall now support writing as well

I increased the virtual memory of sdcard up to 512 MB for the emulator and that was enough

sometimes this can cause of a very simple reason  go to your list in eclipse and check whether you have set SDCard size

User · Answer

I think the problem here is that you forgot to set SD card size  Follow these steps to make it work    step1  close running emulator step2  open Android Virtual Device Manager eclipse menu bar  step3  choose your emulator -  Edit -  then set SD card size   This works well in my emulator

Alternate way  Dismount the drive  from settings storage  and re-mount the sdcard also fixes the problem   verify by moving a file from internal storage to sdcard  In any case  this simple method saved my butt this time

User · Answer

Make sure that you had given a value which is greater than zero for SD Card size in the Create AVD Window for that particular emulator

I tried  user2002993 great help but it one place it need to be a little edit so I edited and here what worked for me on Android Studio  emulator android 5    Go to your adb folder right click on blank area and select  open command window here  or if you installed adb by adb-installer open cmd and type these commands   adb devices   It should show your emulator number and detail  Then followed command here   adb shell   Now it should show you prompt    su  mount -o rw remount rootfs  chmod 777  mnt sdcard  exit  exit   Yeah double exit needed  now your prompt of adb shell is gone  Put a file in to your adb folder and give this command and see if it got fixed   adb push  your file name like   1 jpg   sdcard    or   adb push  your file name like   1 jpg   storage sdcard    Now in cmd it shoudl show you transfer time instead of creepy read-only thing

In adb version 1 0 32 and Eclipse Luna  v 4 4 1     I found a directory in the avd  mnt media rw sdcard that you can write to using the adb command  adb push  source   mnt media rw sdcard  There appears to be rw access to this directory   Hope this helps  -

Give any size to Sdcard in Emulator unchecked the read only option from c  user   android avd -  properties push a file through file explorer restart the Emulator    It will definitely works

Once you started the Emulator from one shell  login to another shell  amp  type   adb shell   You should see   prompt displayed  this is your device emulator  shell  Now   type following command at adb shell   mount -o remount rw  sdcard   This will now remount  sdcard with rw read-write  permission  amp  now you can push your files into  sdcard by using following command from your host shell    adb push filename mp3  sdcard     where filename mp3 could be any file that you want to push into Android Emulator   Hope this helps
