Android 需要动态申请的权限以及EasyPermission 的使用

Android6.0（API 23）以后，一些涉及敏感数据的权限申请需要动态申请了，不能直接在menifest添加就可以用了。

一、需要动态申请的权限

所属权限组	权限
日历	READ_CALENDAR
日历	WRITE_CALENDAR
相机	CAMERA
联系人	READ_CONTACTS
联系人	WRITE_CONTACTS
联系人	GET_ACCOUNTS
位置	ACCESS_FINE_LOCATION
位置	ACCESS_COARSE_LOCATION
麦克风	RECORD_AUDIO
电话	READ_PHONE_STATE
电话	CALL_PHONE
电话	READ_CALL_LOG
电话	WRITE_CALL_LOG
电话	ADD_VOICEMAIL

电话	PROCESS_OUTGOING_CALLS
传感器	BODY_SENSORS
短信	SEND_SMS
短信	RECEIVE_SMS
短信	READ_SMS

短信	RECEIVE_MMS
存储	READ_EXTERNAL_STORAGE
存储	WRITE_EXTERNAL_STORAGE

二、不需要动态申请的权限

三、使用EasyPermission库进行权限动态申请

1、导入easypermission库：

 compile 'pub.devrel:easypermissions:1.0.1'

2、动态申请权限

//所要申请的权限
String[] permsLocation = {Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION};

if (EasyPermissions.hasPermissions(this, permsLocation )) {
  //已经获取所要申请的权限，进行下一步处理
} else {
            
        //没有获取，申请定位权限
        EasyPermissions.requestPermissions(this,"请求获得设备定位权限", 1, permsLocation);
     } 
}

//Android 系统权限结果监听回调
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
     super.onRequestPermissionsResult(requestCode, permissions, grantResults);

     //调用easypermission结果监听返回
     EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}


//easypermission 权限结果监听回调
@Override
public void onPermissionsGranted(int requestCode, List<String> perms) {       
}

@Override
public void onPermissionsDenied(int requestCode, List<String> perms) {
}

 //EasyPermissions.onRequestPermissionsResult 源码
 /**
     * Handle the result of a permission request, should be called from the calling {@link
     * Activity}'s {@link ActivityCompat.OnRequestPermissionsResultCallback#onRequestPermissionsResult(int,
     * String[], int[])} method.
     * <p>
     * If any permissions were granted or denied, the {@code object} will receive the appropriate
     * callbacks through {@link PermissionCallbacks} and methods annotated with {@link
     * AfterPermissionGranted} will be run if appropriate.
     *
     * @param requestCode  requestCode argument to permission result callback.
     * @param permissions  permissions argument to permission result callback.
     * @param grantResults grantResults argument to permission result callback.
     * @param receivers    an array of objects that have a method annotated with {@link
     *                     AfterPermissionGranted} or implement {@link PermissionCallbacks}.
     */
    public static void onRequestPermissionsResult(int requestCode,
                                                  @NonNull String[] permissions,
                                                  @NonNull int[] grantResults,
                                                  @NonNull Object... receivers) {
        // Make a collection of granted and denied permissions from the request.
        List<String> granted = new ArrayList<>();
        List<String> denied = new ArrayList<>();
        for (int i = 0; i < permissions.length; i++) {
            String perm = permissions[i];
            if (grantResults[i] == PackageManager.PERMISSION_GRANTED) {
                granted.add(perm);
            } else {
                denied.add(perm);
            }
        }

        // iterate through all receivers
        for (Object object : receivers) {
            // Report granted permissions, if any.
            if (!granted.isEmpty()) {
                if (object instanceof PermissionCallbacks) {
                    ((PermissionCallbacks) object).onPermissionsGranted(requestCode, granted);
                }
            }

            // Report denied permissions, if any.
            if (!denied.isEmpty()) {
                if (object instanceof PermissionCallbacks) {
                    ((PermissionCallbacks) object).onPermissionsDenied(requestCode, denied);
                }
            }

            // If 100% successful, call annotated methods
            if (!granted.isEmpty() && denied.isEmpty()) {
                runAnnotatedMethods(object, requestCode);
            }
        }
    }
