Short description:
When implementing TileProvider.getTile(int x, int y, int zoom), any RuntimeException your code might be firing will be muted/silenced but the (gms) callers.

How I came by the bug:
This results in code being very hard to debug.
Some tiles wouldn't show up on my map and I spent most of the day looking into my code that fetches and saves my cached tiles before I found out that there was a RuntimeException-derived exception firing in my getTile code. I never seen if because the parent callers ignore the exception and don't print any error nor warning message.

What steps will reproduce the problem? Please provide a link to a
demonstration page if at all possible, or attach code.
1. Add a TileOverlay to your GoogleMap object with the following implementation
public class MyTileProvider implements TileProvider {

public MyTileProvider() {
}

public Tile getTile(int x, int y, int zoom) {
if (true) {
throw new RuntimeException("ashjdasd");
}
return NO_TILE;
}
}
2. The "NO_TILE" tile (or any other tile) isn't returned because the RuntimeException avoided it to be returned, AND The application does not crash AND The application does not print any error nor warning message.

Workaround:
For developers willing to save debugging time, be sure to wrap your code in getTile with a try-catch block, like:
public Tile getTile(int x, int y, int zoom) {
try {
if (true) {
throw new RuntimeException("ashjdasd");
}
return NO_TILE;
} catch (RuntimeException e) {
Log.d("MyTag/MyTileProvider", "getTile x=" + x + ", y=" + y + ", zoomLevel=" + zoom + " raised an exception", e);
throw e;
}
}
