PR #2751 cleaned up UI strings, changing the label from `Show "Get Started" on startup` to `Show this menu on startup`. This change was fine for "Get Started" menu, but the label is confusing when reused on the Keyman Settings menu.
This PR reverts the label (while formatting the string to include the localized string for "Get Started".
Since we're getting away from using the cloud keyboard catalog for adding keyboards, this changes the "Get Started" option "Add a keyboard for your language" to bring up the embedded keyboard search activity.
Fixes#2989
This updates the minimum supported Android SDK to 21 (Lollipop). This applies to KMEA, KMAPro, Sample Apps, KeyboardHarness, and FV Android app.
Tests/keyCode doesn't use KMEA so no change there.
Fixes#2977#2928 removed DejaVuSans.ttf but it turns out the font is still needed for:
* sil_euro_latin OSK to render on Android SDK 19 (KitKat)
* the sample apps and possible 3rd party apps may also be referencing the default font
* Remove handling deprecated keyman:// protocol
* Pass original URL
* lower-case BCP 47 tag when checking for match
* Clean up logic nesting in KMPBrowserActivity
This updates how the Keyman app handles URLs for downloading kmp files (in preparation for keyboard picker revamp).
If the URL contains "language" or "platform", those values are propagated for when the kmp gets downloaded. The "languageID" is then used during kmp installation.
Also fixed a few things with URL handling:
* Catch UnsupportedOperationException if the original URL has invalid query parameters
* Handle DownloadIntentService fails
### User Testing:
Load the Keyman app.
Open a Chrome browser and go to the link:
```
keyman://?filename=sil_cameroon_qwerty.kmp&url=https://keyman.com/keyboard/download?id=sil_cameroon_qwerty&language=bbj-Latn&platform=android
```
The KMP should install and use the specified `bbj-Latn` language (Ghomálá').
Normally, sil_cameroon_qwerty defaults to `aal` (Afade).
On CI, the `android/` folder was getting locked because KeyboardHarness/build.sh would rebuild KMEA without passing `-no-daemon`.
This PR updates KeyboardHarness/build.sh to follow KMAPro and Sample apps build.sh scripts and not build KMEA.
KMEA/build.sh also updated to directly copy the artifact to the KeyboardHarness project
