Thanks. I tried doing that but it seems to be an old API so I tried
to convert it to what is there today. There must be some mistake I
have made that keeps this from working.
Note that it didn't like mResources.startPreloading(); The method
simply was not there, although finishPreloading() is. I commented the
startPreloading() line out.
Secondly, it didn't like the format of the array when it looked like
this:
<array name="preloaded_drawables">
<item>@drawable/sym_def_app_icon</item>
So, I changed that to this:
<array name="preloaded_drawables">
<item type="drawable" name="sym_def_app_icon"></item>
When I execute this line:
TypedArray ar =
mResources.obtainTypedArray(com.standardandroid.swarooms.R.array.preloaded_drawables);
I get a warning:
ResourceType Invalid package identifier when getting bag for
resource number 0x7f050000
Then an exception:
Failure preloading resources
android.content.res.Resources$NotFoundException: Array resource ID
#0x7f050000
at android.content.res.Resources.obtainTypedArray(Resources.java:
424)
Any idea what I am doing wrong?
