Sample hierarchial URL, from my ContactsProvider test case:
content://com.android.contacts/data?account_name=braddroid%40gmail.com&account_type=com.google.GAIA&caller_is_syncadapter=true
Without this patch: (fetching the "account_name" parameter)
10000 iters: 0.5293 ms average
10000 iters: 0.5119 ms average
10000 iters: 0.5158 ms average
With this patch, rewriting it to not allocate memory (no implicit
StringBuilder), but still no caching:
1) when it needs to decode something (i.e account_name above;
allocates memory)
50000 iters: 0.28724 ms average
50000 iters: 0.31774 ms average
50000 iters: 0.28764 ms average
2) when it doesn't need to decode (and thus allocate memory,
i.e. account_type above)
50000 iters: 0.0954 ms average
50000 iters: 0.09124 ms average
50000 iters: 0.09088 ms average
