Android - Application stuck in "Installing..." stage in Market

I just had this problem, and somehow I got this solved.

What I did:

• Entered Settings -> Applications -> Manage Applications.
• Selected the Market app, and "uninstall updates".

After that, I entered the Market app again, and I was able to reinstall the app who got stucked.

PS: I'm not sure if this was just a coincidence, or this procedure works always, but it worked for me. PS2: My Android version is actually in portuguese language, so I'm not sure the option names I referred to above are correct in english.

Try to do the following:

• Close the Play store.
• Go to settings
• Select the apps option
• Find the Google Play store, and select it
• Tap "Storage"
• Select "clear data"

Then, try to download your app again.

In the " downloads" screen of the market, long click on the app that's stuck installing and you'll get the option to Delete or Cancel (I can't remember which option you'll see but it'll be obvious).
