在版本21及以上的设备上运行应用程序时出现java错误？
我正在使用goofence应用程序检测用户位置，但它不支持21岁及以上的设备。我如何在所有设备上使用它
主要活动。爪哇
Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (location == null) {
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, MainActivity.this);
用于接收用户位置并从中接收更新的代码
这是我的主要活动类，如果我添加权限，我也会出错
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED){
Error:(100, 64) error: incompatible types: <anonymous ConnectionCallbacks> cannot be converted to Context.
after implementing permission i get error like this.

问题是，您需要启用运行时权限以促进此类操作
请阅读本页：https://developer.android.com/training/permissions/requesting.html 当应用程序变得可见时执行此检查
