Android Question Key not secure?

I used B4A's keystore system and it works for both Amazon and Google Play store. BUT Google gives me this message:
Security Alert: Your app contains embedded private keys or keystore files

This app contains one or more private keys or keystore files embedded in its published apk as listed at the end of this message. These embedded items can be accessed by third parties, which can raise a variety of different security concerns depending on what the key is used for. For example, if the private key is the signing key for your application, a third party could sign and distribute apps that replace your authentic apps or corrupt them. Such a party could also sign and distribute apps under your identity.

As a general security practice, we strongly recommend against embedding private keys and keystore files in apps, even if the keys are password protected or obfuscated. The most effective way to protect your private key and keystore files are not to circulate them.

Please remove your private keys and keystore files from your app at your earliest convenience.

Did you copy the actual physical keystore file into your project files?

If so you're not supposed to do that.

Thanks! I removed the keystore from files.
But now it won't fully compile:
B4X:
Convert byte code - optimized dex.    (5.56s)
    Optimized dexer failed. Switching to Standard dexer.
Packaging files.    (0.80s)
Copying libraries resources    (0.00s)
Signing package file (private key).    Error

jarsigner error: java.lang.RuntimeException: keystore load: F:\Dropbox\Projects_B4A\_P2E App\Files\key01.keystore (The system cannot find the file specified)

The reason you get this error is because you removed the keystore file from the location you had it.
Just create another directory outside of your project files, for example you can create it in your C:\ drive, and copy the keystore file in that directory, don't forget to change the location of the keystore file under Tools\Private Sign Key in the IDE.

So are you saying keep keystore out of "project/files" but reference it from in the project IDE?
I thought referencing a file would then copy the file into project/files?

Aha! I re-read your message and figured there was only one reference needed, to do it from tools/private sign key in the IDE. As you said. THANKS!
