I have a problem with installing apps from Google Play onto my Samsung Galaxy S Plus phone.

It has Android 2.3.6. Yesterday I tried to download some apps. When I clicked 'Install', the app began to download but when it got to 100% it just disappeared and silently failed to install on my phone :\

I don't have an SD card and up to now I saved all my apps on the phone and had no problems like this. It seems to be some settings problem, but I don't know what to do. any ideas?!

Do you have access to the device log (logcat)? That's sadly a chicken & egg problem (you'd need some additional app to see logs, e.g. play.google.com/store/apps/details?id=com.nolanlawson.logcat and attach the output from a failed install attempt to this question). That can also be done by installing the SDK and use the integrated log viewer from there, but that's not too straightforward. –  ce4 Jul 5 '12 at 12:31
Is there sufficient space available on your phone to install the apps? –  Bryan Denny Jul 5 '12 at 13:34
It sounds to me like the infamous /cache or /data/data out of space problem. I hope google addresses this issue and gives more space for these mounts. Usually there is plenty of room to install in /data/app, but the cache and data locations run out of room quickly. –  Ryan Conrad Jul 5 '12 at 21:03

Before uninstalling updates I would also try Clear Data (same place - under Google Play in Application Manager). That fixed the same issue for me.

You either ran out of space, or you had updated Google Play.

Someone already solved this without rooting the phone by uninstalling updates for Google Play Store app: Go to Settings → Applications → All (tab), scroll down and tap "Google Play Store", then "Uninstall updates".

I was having a similar problem. When trying to install an app from the market, it would get to 100% download, then say download failed. Also, the same behavior occurred with updates to previously installed apps. Tried all sorts of things from various forms and nothing worked.

I am running Eclair, and decided that my phone was becoming a paperweight without these updates... So I resolved to install a new ROM, thankfully I did not have to go that far. I ran a one-click root application, and afterwards I could download updates and install new apps without issue.

Pretty sure rooting your phone will void the warranty, if that is not of concern and your at a dead end... perhaps give it try, it worked for me.

I'm sure there must be other solutions as well, apart from installing different ROM. I get similar problem sometimes on my HTC Desire but it works after some retry. –  roxan Sep 19 '12 at 8:26

Its indeed quite possible that either the two directories residing on the filesystem, /data/local/download or /cache/download is probably full of temporary files and is not deleted which contributes to the symptoms of the app not installing after 100% downloaded.

Some ROMs do have this facility or feature in place, called run-parts, which is invoked by the busybox which does this clean up on boot to clear out the temporary downloaded files saved in the specified directories. Again, this is dependant on the ROM.

Maybe that's what you should try doing, reboot to force the system to clean up the directories and try again upon bootup?

If that fails, then it sounds likely that the /cache partition is very small not to hold the downloaded files. The trick employed by ROMs is this, the /cache/download is either sym-linked to /data on the /data partition. The other trick is that /data/local/download is re-binded to the /cache/download directory. (see this script below to see what the second trick is about)

# bind mount /data/local/download to /cache/download if cache
# partition is too small

CACHESIZE=$(df /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2 | tr -d [:alpha:])
DATAONLY=$(getprop dalvik.vm.dexopt-data-only)
if [ $DATAONLY -eq 1 ]

  /system/xbin/busybox mount -o bind /data/local/download /cache/download

rm /cache/download/downloadfile*.apk >/dev/null 2>&1

exit 0

Why /cache and /data/local/download? it is found in the init.rc script in the ramdisk of the ROM in question which has the following environment variables that tells the Google Play store, where to save the downloaded apps.

export ANDROID_CACHE /cache
export DOWNLOAD_CACHE /cache/download

The only thing I would suggest is to use File Explorer (just as I type this I realised yeah, root... but I digress), and clean out the directory manually for a start.
