定位、读取手机状态等权限在6.0系统不管用

判断版本号，如果是6.0以上，在代码中加入需要的权限，可以为多个权限，也可以为一个权限

if(Build.VERSION.SDK_INT >= 23){
requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_PHONE_STATE},REQUEST_CONTACTS);
}

重写方法，判断如果没有加上权限的操作，或加入权限的操作
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode==REQUEST_CONTACTS){
if (PermissionUtil.verifyPermissions(grantResults)) {

}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

权限的util

package com.yjkj.sandihuabing;

import android.content.pm.PackageManager;

/**

public abstract class PermissionUtil {

public static boolean verifyPermissions(int[] grantResults) {
// At least one result must be checked.
if(grantResults.length < 1){
return false;
}

// Verify that each required permission has been granted, otherwise return false.
for (int result : grantResults) {
if (result != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
return true;
}

}
