I had a small amount of ether stored in a wallet i downloaded from the appstore (on android). Unfortunately my phone broke and now I cant find the same app on the store anymore. I tried finding the app from the "my apps and games" page on google play but it seems like the app is no longer there on the store.
I had emailed myself the "private key" earlier as a backup just in case. The problem I am running into now is that the backup that I had done was simply clicking on the backup button on the app and emailing whatever file it generated to myself. I never checked the file or the key at the time.
Now that I see, the file has my ether address and a .key extension. I tried searching the internet and it said that it was an iOS keynote file, but keynote isn't able to access it either.
I'm trying to retrieve the either by linking it to a new metamask account by linking the private key. If someone could help me with if and how I can open the file I'd be really grateful.
Thanks in advance.
