Android 自动拨打电话功能可以通过以下步骤实现：
1. 在 AndroidManifest.xml 文件中添加拨打电话的权限：
```
<uses-permission android:name="android.permission.CALL_PHONE" />
```
n2. 在代码中使用 Intent 启动拨打电话的界面：

```
String phoneNumber = "10086";
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
startActivity(intent);
```
注意：使用 ACTION_CALL 需要在 AndroidManifest.xml 文件中添加以下权限：
```
<uses-permission android:name="android.permission.CALL_PHONE" />
```
如果不想直接拨打电话，而是想跳转到拨号界面，可以使用 ACTION_DIAL：
```
String phoneNumber = "10086";
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + phoneNumber));
startActivity(intent);
```
这样就可以实现 Android 自动拨打电话功能了。
