Fill-drawables not (yet) supported below API level 18, this

Error message

Fill-drawables not (yet) supported below API level 18, this code was run on API level {Utils.getSDKInt()}.

What it means

Thrown by LineRadarRenderer when a Fill is configured to use a Drawable but the runtime API level is below 18 (Android 4.3). Clip-path + drawable drawing relies on Canvas.clipPath hardware acceleration behavior that is unreliable before API 18, so the renderer refuses to draw rather than render incorrectly. The actual SDK level is interpolated into the message.

Solutions

1. Raise minSdkVersion to 18 (or higher) if your device matrix allows it.
2. Gate drawable fills at runtime: if (Utils.getSDKInt() >= 18) set.setFillDrawable(d); else use a solid color Fill.
3. Use Fill.Type.COLOR (solid color) or a gradient shader instead of a Drawable for pre-18 devices.
4. Filter the feature in build flavors so legacy builds never configure drawable fills.

Example fix

// before
Fill fill = new Fill(d -> drawable);
lineDataSet.setFill(drawableFill); // crashes below API 18

// after
Fill fill;
if (Utils.getSDKInt() >= 18) {
    fill = new Fill(myDrawable);
} else {
    fill = new Fill(Color.parseColor("#33000000"));
}
lineDataSet.setFill(fill);

if (Utils.getSDKInt() >= 18) {
    lineDataSet.setFillDrawable(myDrawable);
} else {
    lineDataSet.setFillColor(fallbackColor);
}

boolean supportsDrawableFill() {
    return Utils.getSDKInt() >= 18;
}

When it happens

Trigger: Setting a line/radar Fill with setFillDrawable(...) or Fill.setType(Fill.Type.DRAWABLE) and running the app on a device/emulator below Android 4.3 (API 17 or lower). Running instrumentation tests on a low-API emulator.

Common situations: Shipping to legacy devices; minSdkVersion < 18 while using drawable fills; CI matrix that includes older emulator images; using gradient/bitmap drawables for area fills without gating on API level.
