Question: Being frustrated with the speed of the android emulator running on a ARM image, as soon as I discovered the intel atom image I used it right away. There was a immediate speed boost (boot going from 30 sec to 3 sec) but my application no longer works completely. All the XML portions of the app work, but as soon as I move to my activity which is all surfaceview and canvas work the screen goes black. It does not crash and there are no errors in logcat. The stranger thing is that I have a previously developed application which implements similar things (canvas and surfaceviews mostly) which works fine on the new image. 

Does anyone have any idea why this would be happening?

System Information: Hardware: intel xeon quad core processor; 6 gb RAM, Nvidia 610 graphics card
OS: Ubuntu 13.04 64 bit

Answer: 
If you are printing the numbers with `+` in between, then you can go with any one of [Kevin's](https://stackoverflow.com/a/17125361/970195) answer. 

However, if you wish to truly `add` them then the following should work:

```
awk 'NR==FNR{a[$1$2]=$3;next}{$NF=$NF+a[$1$2]}1' file1 file2

```
Try this (if it helps) ... simple use of paste and awk 

**Input1.txt**

```
A yield 123
B yield 345
C yield 165

```

**Input2.txt**

```
A yield 456
B yield 5675
C yield 34534

```

**Code**

1. If you wish the add the numbers

paste -d ' ' Input1.txt Input2.txt | awk -F " " '{print $1 " " $2 " " $3+$6}'
2. If you wish to just print '+' sign in between the numbers

paste -d ' ' Input1.txt Input2.txt | awk -F " " '{print $1 " " $2 " " $3"+"$6}'
