动态申请权限：

在Android 6.0及以后，将权限分为普通权限和危险权限，普通权限可以直接在manifest中申请，而危险权限需要在Java代码中动态申请；
在Android 6.0中，申请一个危险权限的同时，会将同组的危险权限一并授权给应用，例如在授权READ_EXTERNAL_STORAGE
的时候，WRITE_EXTERNAL_STORAGE会自动授权；
在Android 8.0 中这一点被修改，危险权限不会随同组权限一并授权，需要用一个授权一个，但是同组后面申请的权限不会弹框通知用户

普通权限：

ACCESS_LOCATION_EXTRA_COMMANDS
ACCESS_NETWORK_STATE
ACCESS_NOTIFICATION_POLICY
ACCESS_WIFI_STATE
BLUETOOTH
BLUETOOTH_ADMIN
BROADCAST_STICKY
CHANGE_NETWORK_STATE
CHANGE_WIFI_MULTICAST_STATE
CHANGE_WIFI_STATE
DISABLE_KEYGUARD
EXPAND_STATUS_BAR
GET_PACKAGE_SIZE
INSTALL_SHORTCUT
INTERNET
KILL_BACKGROUND_PROCESSES
MODIFY_AUDIO_SETTINGS
NFC
READ_SYNC_SETTINGS
READ_SYNC_STATS
RECEIVE_BOOT_COMPLETED
REORDER_TASKS
REQUEST_INSTALL_PACKAGES
SET_ALARM
SET_TIME_ZONE
SET_WALLPAPER
SET_WALLPAPER_HINTS
TRANSMIT_IR
UNINSTALL_SHORTCUT
USE_FINGERPRINT
VIBRATE
WAKE_LOCK
WRITE_SYNC_SETTINGS

危险权限一共9组共24个：

group:android.permission-group.CONTACTS						
  permission:android.permission.WRITE_CONTACTS
  permission:android.permission.GET_ACCOUNTS
  permission:android.permission.READ_CONTACTS

group:android.permission-group.PHONE							
  permission:android.permission.READ_CALL_LOG
  permission:android.permission.READ_PHONE_STATE
  permission:android.permission.CALL_PHONE
  permission:android.permission.WRITE_CALL_LOG
  permission:android.permission.USE_SIP
  permission:android.permission.PROCESS_OUTGOING_CALLS
  permission:com.android.voicemail.permission.ADD_VOICEMAIL

group:android.permission-group.CALENDAR
  permission:android.permission.READ_CALENDAR
  permission:android.permission.WRITE_CALENDAR

group:android.permission-group.CAMERA
  permission:android.permission.CAMERA

group:android.permission-group.SENSORS
  permission:android.permission.BODY_SENSORS

group:android.permission-group.LOCATION
  permission:android.permission.ACCESS_FINE_LOCATION
  permission:android.permission.ACCESS_COARSE_LOCATION

group:android.permission-group.STORAGE
  permission:android.permission.READ_EXTERNAL_STORAGE
  permission:android.permission.WRITE_EXTERNAL_STORAGE

group:android.permission-group.MICROPHONE
  permission:android.permission.RECORD_AUDIO

group:android.permission-group.SMS
  permission:android.permission.READ_SMS
  permission:android.permission.RECEIVE_WAP_PUSH
  permission:android.permission.RECEIVE_MMS
  permission:android.permission.RECEIVE_SMS
  permission:android.permission.SEND_SMS
  permission:android.permission.READ_CELL_BROADCASTS

动态申请危险权限主要有几个方法：

//检查SDK版本是否大于23
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)

//检查某权限是否已经动态获取
ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED 

//动态获取权限
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CAMERA}, 1);
//动态获取权限组
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.Manifest.permission_group.CAMERA}, 1);

//权限授权回调
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
	 if (requestCode == 1) {					//这里的requestCode 就是动态申请权限时传入的最后一个参数
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
				
            } else {

            }
    }
}
