You need to download a standalone flash player to play coc1 nowadays.
Did you read the title? This is for Android.
Every time I boot it up, or try, it will flash and then close it self and then tell me that it was made for an older version of Android.
Yeah, unfortunately it seems like the newer versions of Android might no longer have support for the version of Android the game was made with.
Not sure of a possible solution, although it might be worth asking a moderator like Savin or Fenoxo.
Other than that if you have the ability to play it on a computer, all you need is a flash projector,
a list of ones can be found here, and you should still be able to play the game via the download (the one that says CORRUPTION OF CHAMPIONS Download (Right-click, Save-as) on the
play page), as Shrike mentioned (steps are open the flash projector, click open file, then locate the .swf CoC file, and the game will start).
