Distribute android app release version without certificate

Question

Not going to distribute the app just want to release a react-native app for testing without debugging mode .

I use this ./gradlew assembleRelease to compile a release version.

When I try to install it adb install app-release-unsigned.apk , it give me this error:

Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

What is the error?

Can I distribute it without signing?

Answer 1

No, Android will only install signed APKs. Even debug versions are signed, they're signed with a debug key Android Studio creates when its run the first time. You don't have to sign it with your release key though if you don't want to.

Answer 2

将apk转移到设备上，您可以使用Play商店中名为apk-signer的应用，该应用将为apk提供签名，然后您可以安装或分发
