here is the image. I can't find my app's process, but others I can see. why did this happen? what should do? Thanks.

if you get errors like below:

• Unable to get view server version from device;
• Unable to get view server protocol version from device
• Unable to get the focused window from device
• Unable to debug device

try to check these points below:

• if signed app running on the phone, DDMS can't get the process info; otherwise, can.
• if use Virtual Device, then the DDMS&HierarchyView is useful;
