android tv outofmem,java.lang.OutOfMemoryError:尝试抛出OutOfMemoryErr...
我正在尝试将用户提供的lat long值与数据库中的lat long值进行比较.如果它们彼此的半径在15 km之内,则应更改textview.
但是我面临以下错误,
我的数据库包含值来源lat = 19.218418源长= 73.08661
Des lat = 18.9766017 des long = 72.8326658.用户提供的值是
源纬度= 19.2213935源纬度= 73.081532目标纬度= 18.9632933经度纬度= 72.8324848.
