When a Titanium SDK build fails, the root cause may be an incorrectly configured Android SDK location, but it is unclear how the CLI interprets the ANDROID_SDK environment variable versus explicit command‑line flags. Identifying whether the failure stems from a missing path, a mis‑typed variable, or an omitted flag requires examining the build output.
How should the ANDROID_SDK environment variable be configured so that the Titanium CLI recognizes it reliably? What specific patterns in the build log (e.g., Unable to locate SDK or android.jar not found) most clearly point to an SDK path problem? Can the SDK path be passed directly to the build command, and if so, what syntax is required?

When a Titanium SDK build fails because the Android SDK cannot be located, the first step is to confirm how the build tools are receiving the SDK location.
Ensure that the ANDROID_SDK environment variable is set to the absolute path of the Android SDK root directory (the folder that contains platforms/, tools/, etc.). You can check its value in the terminal with:
appceleratorecho $ANDROID_SDK # on macOS/Linux
echo %ANDROID_SDK% # on WindowsIf the variable is empty or points to a non‑existent directory, the Titanium CLI will not be able to locate the SDK.
Run the build command again and look for any lines that indicate the SDK could not be found. Typical wording (as described in the Titanium documentation) includes phrases such as "Unable to locate Android SDK" or references to missing android.jar. The presence of such messages strongly suggests a path configuration problem.
Some Titanium CLI versions allow overriding the SDK location with a command‑line flag, often formatted as:
titanium build --android-sdk /path/to/android-sdkConsult the specific version’s help output (titanium build --help) to confirm the exact flag name and syntax.
Use comments to ask for clarification. Post a solution as an answer.

While environment variables are a common starting point, it is important to verify the android.sdk.path property within the titanium.properties file. The Titanium CLI often prioritizes this internal configuration over system-level variables like ANDROID_SDK or ANDROID_HOME.
If the build continues to fail despite a correct environment variable, check the following:
titanium.properties file located in your user home directory to ensure the path is absolute and points to the SDK root.platform-tools and build-tools subdirectories; if these are missing, the CLI may report the SDK as "not found" even if the root folder exists.
