developer.android.com has a nice writeup on how to setup a hardware android device for application testing on the Using Hardware Devices page. It also gives a list of USB Vendor IDs, which are required to setup your hardware device. But the list of vendors may not include your Chinese / Unbranded android phone or tablet. For eg. The vendor ID of a NATPC/MID tablet is apparently not on the list of vendor ids which includes the likes of HTC, Asus, Google,Foxconn, etc. In such a case, these are the errors you may get: On selecting Run app in Eclipse, you are greeted with a prompt asking you to select an Android Device.

While making pointers.c in the Week 5 lecture, I came across this error $make pointers cc     pointers.c   -o pointers pointers.c: In function ‘main’: pointers.c:27:5: error: ‘for’ loop initial declarations are only allowed in C99 mode pointers.c:27:5: note: use option -std=c99 or -std=gnu99 to compile your code make: *** [pointers] Error 1 If instead of using make, you use gcc pointers .c you will get a similar error. To correct this, I ran $gcc pointers.
