add array in R$styleable.smali its bunch of public ids of attr

[ you can see array at end of R$styleable ]

(

example:

.line 12842
:array_0
.array-data 4
0x1010034
0x1010095
0x1010096
0x1010097
.end array-data

)

array 9

dependOnResource to hasMetaData

array 10

chooserTitle and summaryValues

array 11

valueOfSystemProperty to valueOnExtraStatusName

array 9 , 10, 11 are like this for me

.line 13748
:array_9
.array-data 4
0x7f01003a
0x7f01003b
0x7f01003c
0x7f01003d
0x7f01003e
0x7f01003f
0x7f010040
0x7f010041
0x7f010042
0x7f010043
0x7f010044
.end array-data

.line 13768
:array_10
.array-data 4
0x7f010045
0x7f010046
.end array-data

.line 13798
:array_11
.array-data 4
0x7f010047
0x7f010048
0x7f010049
0x7f01004a
0x7f01004b
0x7f01004c
.end array-data
