[ Merge of http://go/wvgerrit/70203 ] The earlier property_get() method had a limitation on property length. Properties of some new devices exceed that length. An error message is returned rather than a truncated string. Replace its use with android::base::GetProperty() which does not have a length limitation. Bug: 115358798 Test: WV unit/integration tests Change-Id: I46ce9a7e77bcd031225d0082f83c57d484fe5405
