android动态申请权限6.0（SDK23）以上

示例：获取读写权限

1、同样需要在清单文件里面配置

   <uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS"/>

2、然后再动态申请 

 //申请权限
    public void applyPermission() {
        //判断是否已经赋予权限
        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.WRITE_CONTACTS)
                != PackageManager.PERMISSION_GRANTED) {
            //用户是否上次拒绝权限申请（第二次打开）
            if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.WRITE_CONTACTS)) {
                //用户已经拒绝过一次，需要提示用户去设置里面授权
                Log.e("AddressBook", "用户上次拒绝权限申请");
            } else {
               //申请权限，定义数组会一次申请多个权限
                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_CONTACTS}, 100);
            }
        } else {
            Log.e("AddressBook", "还没有赋予权限");
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 100) {
            for (int i = 0; i < permissions.length; i++) {
                if (grantResults[i] == PERMISSION_GRANTED) {
                    Log.e("AddressBook", "权限" + permissions[i] + "申请成功");
                } else {
                    Log.e("AddressBook", "权限" + permissions[i] + "申请失败");
                }
            }
        }
    }
