Failed Generate Signed Bundle / APK

Question

An android project, which was initially published in google playstore needed few updates. After the changes, the Generate Signed Bundle / APK is not generating any file. It does not give any message or warning in the event log.

It generates unsigned release files when using Build > Generate APK. That file is rejected by google play store with the following message.

You uploaded an APK with an invalid signature (learn more about signing). Error from apksigner: ERROR: JAR_SIG_NO_SIGNATURES: No JAR signatures

I have also read the questions 1 2, but this is different.

did you mark the checkbox in Signature Version before release? Also it is better to upload you AAB to google play rather than just you APK — L2_Paver, Oct 16 '19 at 02:02

Just check whether you are checking the Signature checkbox before you generate a signed apk.

When you are going into Generate signed bundle/APK, make sure to check two boxes that are about signing APK.

Those two checkboxes are at the last step of making the APK, right before you click on Finish.

The simplest answer is that you cannot upload an unsigned apk to play store. You need to create a signed build apk and then you will be able to upload your apk to playstore.
