Android 64-bit Package Compilation Fails in Delphi 12 After SDK Update Prompt ([Error] Failed)

[dmitrybv 5]

Product and Version:
Embarcadero® RAD Studio 12 — Version 29.0.55362.2017
Installed from: RADStudio_123_2017_E9E8FB1D4F9F.iso (7,256 MB)

Platform: Android 64-bit

Issue Description:
When attempting to compile a runtime package for the Android 64-bit platform in Delphi 12, I receive the following warning:

Would you like to update the platform SDK now?

Regardless of whether I choose Yes or No, the build immediately fails with the error:

[Error] Failed

In Tools → Options → Deployment → SDK Manager → Android 64-bit, several fields (e.g., SDK paths or tools) are marked with exclamation marks (!), although I did not encounter any errors during installation.

File sizes of installed Android SDK components:

• CatalogRepository\AndroidSDK-2525-23.0.55362.2017 — 159 MB

• CatalogRepository\AndroidSDK-NDK-23.0.55362.2017 — 981 KB

The SDK and NDK appear to be partially installed or missing components, but no installation errors were reported.

Questions:

• What is the reason for the exclamation marks in the SDK Manager?

• Why does the build fail with [Error] Failed after the SDK update prompt?

• How can I fully verify and repair the Android 64-bit platform SDK installation?

What I’ve tried:

• Clicking Yes or No on the SDK update prompt makes no difference — the build still fails.

• I haven’t manually modified the SDK folders.

• The SDK was installed by the ISO installer without any visible issues.

Any guidance on resolving this issue would be appreciated.
