If you install RAD Studio XE7 and then upgrade Android SDK to version 23, you won’t be able to deploy applications to Android devices anymore.
The reason for that is that ZipAlign.exe was moved out of sdk\tools folder in SDK 23 and XE7’s deployment process cannot find it anymore. Now it is located in sdk\build-tools\20.0.0, but only is Android SDK Build-tools rev. 20 are installed, which doesn’t happen automatically.
To fix my Delphi I first had to install Build tools rev. 20. Then I copied sdk\build-tools\20.0.0\zipalign.exe to sdk\tools\zipalign.exe. That fixed the deployment problem.
I’m hoping Embarcadero will fix this in the next update, but for now you can use this workaround.
[Android sdk folder can be found in c:\Users\Public\Documents\Embarcadero\Studio\15.0\PlatformSDKs\adt-bundle-windows-x86-20131030\sdk]
