Grantor是为了解决android 6.0 及以上版本的动态权限的第三方框架，使用简单。

1.添加依赖在module's dependencies中

//导入grantor依赖
dependencies {
      implementation'com.github.dfqin:grantor:2.5'
}

2.使用实现两个方法

PermissionsUtil.requestPermission(Context context, PermissionListener listener, String[] permissions);

3.使用案例

private void requestCemera() {
        PermissionsUtil.requestPermission(getApplication(), new PermissionListener() {
            @Override
            public void permissionGranted(@NonNull String[] permissions) {
                Toast.makeText(MainActivity.this, "访问摄像头", Toast.LENGTH_LONG).show();
            }

            @Override
            public void permissionDenied(@NonNull String[] permissions) {
                Toast.makeText(MainActivity.this, "用户拒绝了访问摄像头", Toast.LENGTH_LONG).show();
            }
        }, Manifest.permission.CAMERA);
    }


    private void requestReadContact() {
        PermissionsUtil.TipInfo tip = new PermissionsUtil.TipInfo("注意:", "我就是想看下你的通讯录", "不让看", "打开权限");
        PermissionsUtil.requestPermission(this, new PermissionListener() {
            @Override
            public void permissionGranted(@NonNull String[] permissions) {
                JSONArray arr = null;
                try {
                    arr = getContactInfo(MainActivity.this);
                    if (arr.length() == 0) {
                        Toast.makeText(MainActivity.this, "请确认通讯录不为空且有访问权限", Toast.LENGTH_LONG).show();
                    } else {
                        Toast.makeText(MainActivity.this, arr.toString(), Toast.LENGTH_LONG).show();
                    }

                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

            @Override
            public void permissionDenied(@NonNull String[] permissions) {
                Toast.makeText(MainActivity.this, "用户拒绝了读取通讯录权限", Toast.LENGTH_LONG).show();
            }
        }, new String[]{Manifest.permission.READ_CONTACTS}, true, tip);
    }

    private void requestSms() {

        PermissionsUtil.requestPermission(this, new PermissionListener() {
            @Override
            public void permissionGranted(@NonNull String[] permissions) {
                Toast.makeText(MainActivity.this, "访问消息", Toast.LENGTH_LONG).show();
            }

            @Override
            public void permissionDenied(@NonNull String[] permissions) {
                Toast.makeText(MainActivity.this, "用户拒绝了读取消息权限", Toast.LENGTH_LONG).show();
            }
        }, new String[]{Manifest.permission.READ_SMS}, false, null);
    }

PermissionsUtil.TipInfo//这个方法可以做一些提示信息

注：除了在PermissionsUtil.requestPermission最后加Manifest.permission还需要在Manifest清单文件配置

最后加上GitHub地址
