Android L Developer Preview包丢失了吗? [英] Android L Developer Preview packages missing?

问题描述

我正在尝试使用Android L Developer Preview SDK，特别是Bluetooth Low Energy类.我设置了compileSdkVersion 'android-L'，minSdkVersion 'L'和targetSdkVersion 'L'.我可以在外部库"下看到L平台SDK，但是当我去查看android.jar中的内容时，缺少android.bluetooth.le包.因此，我不能使用任何Bluetooth LE类，例如BluetoothLeScanner和ScanCallback.有人知道如何解决这个问题吗?

I'm trying to use the Android L Developer Preview SDK, specifically the Bluetooth Low Energy classes. I set compileSdkVersion 'android-L', minSdkVersion 'L', and targetSdkVersion 'L'. I can see the L platform SDK under "External Libraries", but when I go to see what is inside the android.jar, the android.bluetooth.le package is missing. Thus, I cannot use any of the Bluetooth LE classes such as BluetoothLeScanner and ScanCallback. Does anyone know how to fix this?

推荐答案

我想这是Android Studio中的一个错误(也有一些其他API对此有报道)...

I would guess this is a bug in Android Studio (there are some other APIs for which this has been reported too)...

如果您编写类似这样的内容:

If you write something like:

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
android.bluetooth.le.BluetoothLeScanner scanner = adapter.getBluetoothLeScanner();

然后在Android Studio中确实将其报告为错误.但是，使用gradlew build时，它可以构建正常.

then this is indeed reported as an error in Android Studio. However, it does build ok when using gradlew build.

简而言之，您可以使用它，但这确实很尴尬.我希望这个问题会尽快解决.

In short, you can use it, but it's really awkward. I hope this will be fixed soon.
