Java源主场迎战Android SDK中的差异？ [英] Java source vs. Android SDK differences?

问题描述

如果我看源$ C ​​$ C为 AudioManager ，有：

If I look at the source code for AudioManager, there is:

@SdkConstant(SdkConstantType.BROADCAST_INTENT_ACTION)
public static final String VOLUME_CHANGED_ACTION = "android.media.VOLUME_CHANGED_ACTION";

不过，是不可见的由Eclipse的，即使你指定的最低水平SDK

However, is not visible by Eclipse, even when you specify the minimum SDK level.

怎么能这样呢？

是API的这一部分不？

Is this part of the API or not?

感谢

推荐答案

您错过了以上的部分，表明它的@hide不包含在SDK：

You missed the part above, the @hide indicating it is not included in the SDK:

/**
 * @hide Broadcast intent when the volume for a particular stream type changes.
 * Includes the stream, the new volume and previous volumes
 *
 * @see #EXTRA_VOLUME_STREAM_TYPE
 * @see #EXTRA_VOLUME_STREAM_VALUE
 * @see #EXTRA_PREV_VOLUME_STREAM_VALUE
 */
