How can I make rounded only one edge of the rectangle?

Question

I have the following code:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
       <stroke android:color="@color/conversation_border" android:width="1dp"/>
       <solid android:color="@color/conversation_is_user_bg"/>
            <corners android:radius="1dp" />
            <padding android:left="7dp" android:top="1dp" android:right="1dp" android:bottom="7dp"/>  
</shape>

When i apply it to TextView, all is OK. but when i replace

<corners android:radius="1dp" />

with

<corners android:bottomLeftRadius="8dp"
          android:topLeftRadius="0"
          android:topRightRadius="0"
          android:bottomRightRadius="0" />

I have anexception. I already tried not to remove android:radius attribute, provide radius in px and dp, and result is always

error!
UnsupportedOperationException: null

which is very descriptive. What am I doing wrong and how to round only bottom left corner of the text view?

That is a bug in android ,this code will work perfectly in android devices running on version 2.2 or above . — Sandeep, Jul 29 '11 at 12:15
i was having the same problem in android 1.6 device but worked perfectly in 2.2 — Sandeep, Jul 29 '11 at 12:20
hmm... i'll try it with other versions and post you back if it is working or not — Raiv, Jul 29 '11 at 12:21
check this link http://code.google.com/p/android/issues/detail?id=9161 — Sandeep, Jul 29 '11 at 12:31
yes,that was a bug in android. i misspelled version of emulator, I has r1, not r2 here. And after upgrade to r2 it works fine, yet with inverted corners as in your link, but at least it shows corners. Thank you! — Raiv, Jul 29 '11 at 12:38

Just leave one option:

<corners 
    android:bottomLeftRadius="8dp"
/>

So it must be something else than shape. Could you paste stacktrace? – pawelzieba Jul 29 '11 at 12:20

try this one...

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/corners_blue_random">
    <solid android:color="@color/conversation_is_user_bg" />
    <corners android:radius="1dip" android:bottomLeftRadius="8dip"
        android:topLeftRadius="1dip" android:bottomRightRadius="1dip"
        android:topRightRadius="1dip" />
    <stroke android:color="@color/conversation_border"
        android:width="1dp" />
</shape>

That was a bug in android emulator, thanks to all who answered. After updating emulator to latest version all is working without modifications (exept this bug , but there is walkaround for it)
