Ionic 3.6 Build Error

Ionic Framework ionic-v3
1

Randomly my build fails when I run

ionic cordova  run android

It fails with following error:

:\androidSdk\platform-tools\adb.exe: Command failed with exit code 1 Error output:
Failed to install F:/[Ionic Project Root]/platforms/android/build/outputs/apk/android-debug.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data
/app/vmdl1815657945.tmp/base.apk using APK Signature Scheme v2: SHA-256 digest of contents did not verify]

[ERROR] An error occurred while running cordova run android (exit code 1).

Why does this happen? And how can I solve this?

Removing and re-adding the Android platform will probably fix this. Maybe there even is a clean command that might be enough, don’t remember right now.

But I cannot keep adding and removing platform every time I see that error right?
Plus the build time is usually 1.5 - 2 mins for me.
My Machine Config is:
12 GB RAM
500GB SSD HDD
i5 2nd Gen Processor
And still it takes long time to build an APK.
And some times like in 5 attempts I see this error 3 times.
So usually I spend 5-8 mins only building the APK.

Do anybody know why the error props up?

From looking at the error message

I would guess something is messing with your files during the build process. Anti virus, broken hard disk, security software…

But this is just a guess.
