[darcywong00]

For investigating KEYMAN-ANDROID-251

No keyboards or predictive text to install

This adds a breadcrumb to get more info why a kmp file fails to install.

But it already has a breadcrumb for that: in my experience, the following breadcrumb always appears in the logs of that event (KEYMAN-ANDROID-251) and one other:

keyman/android/KMEA/app/src/main/java/com/keyman/engine/packages/PackageProcessor.java

Line 452 in 7ab6887

KMLog.LogBreadcrumb(TAG, "Determining package type for " + kmpFilename, false);

See also KEYMAN-ANDROID-4G.

In the instances I investigated, the packages turned out to be for legacy keyboards that were never designed with mobile / web in mind. @mcdurdin actually prompted that investigation, anticipating that analysis to be the case. So, "working as expected."

Ok, going back to draft to analyze. I wonder if we set addStackTrace to true
