Gps代码没有错但是代码下面有红线 运行没问题可以真机Android

Question

怎么解决这个问题啊

Answer 1

需要

add permission check

一个办法是将划红线代码放入 try/catch块。

try {
  Location location = locationManager.getLastKnownLocation(provider);
} catch (SecurityException e) {
   e.printStackTrace(); // lets the user know there is a problem with the gps
}
