I get a 'java.lang.ArithmeticException: divide by zero' exception when programmatically building a table layout with setStretchAllColumns(true). If I comment out the line with setStretchAllColumns(true), I don't get the exception, but nothing renders on the screen. Also, I'm new to android development, so please let me know if it's just something I'm doing wrong.

Here's the stack trace:

Forgot to mention:

Emulator of Android V2.1-update1
API Level: 7
CPU/ABI: ARM(armeabi)
Eclipse Indigo

Actually I resolved this by using TableRow.LayoutParams instead of TableLayout.LayoutParams. Please close the bug.

Try a reboot emulator or even on your device.
Worst case, clean project and try a different emulator version.

You can run into the same issue setting a android:stretchColumns of "*" in an XML file. An example and its explanation is here:

It does still occur in Android 4.x. This condition (no views/rows added to the table yet) should be properly handled in the android code.

Status: Won't Fix (Obsolete)

Based on its date, this issue was originally reported before Android 4.x. Because of the many changes that existed in Android 4.x compared to previous versions, it's very likely that this issue doesn't exist in recent versions of Android like 4.2.2 or newer. Because of the high likelihood that this issue is obsolete, it is getting closed automatically by a script, without a human looking at it in detail. If the issue still exists on a Nexus 4 or Nexus 7 running Android 4.2.2 and is not related to Google applications, please open a new report accordingly.

This still occurs with the 5.1.1 SDK, with a div by zero crash in TableLayout.mutateColumnsWidth. The findLargestCells method probably should be amended to handle the case where a row has no columns.
