First, getAccounts*() will now return all available accounts depending on both GET_ACCOUNTS grants and signature matching. This is different from before where a caller of getAccounts() would need GET_ACCOUNTS to get any accounts, but if that same caller called getAccountsByType, they might have gotten back accounts if they shared a signature with the same developer. Second, cleaned up some NPEs and javadoc. This change was motivated by progress on the cts tests. Change-Id: I2f36226780e074fdf58214b46de3b79d8319ace1
