[Android] INSTALL_PARSE_FAILED_NO_CERTIFICATES

설치하고자 하는 앱에 서명이 되어있지 않기 때문에 발생하는 문제입니다.

아래와 같이 앱 서명을 진행하시면 됩니다.

1. Build > Generate Signed APK...

2. If you don't have a key store, you need to create via "Create new..".

If you already had it, you need to choose it via "Choose existing..".

And then, you need to input Key store password / Select Key alias / Input Key password.

3. Select APK Destination Folder > Build Type : release > Check V1 and V2 > Finish

4. Building

5. Done

 

 

The built APK should have below ceritification information.

 

You can check this via "Analyze APK..." Tool.
