考虑以下无用code在Android活动：

Consider the following useless code in an Android activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String s1 = Intent.ACTION_PACKAGE_CHANGED;
    String s2 = Intent.ACTION_QUERY_PACKAGE_RESTART;
}

为什么Eclipse中引发的 ACTION_QUERY_PACKAGE_RESTART不能得到解决或不是一个字段错误？我的意思是，不是由 Intent类？

Why does Eclipse raise an ACTION_QUERY_PACKAGE_RESTART cannot be resolved or is not a field error? I mean, aren't both the two strings defined by the Intent class?

应用程序使用：

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="17" />

但把两个17不会改变Eclipse的行为。

but putting both to 17 doesn't change Eclipse behaviour.

推荐答案

这是从SDK隐藏，因为它只是为了在内部使用。这就是为什么它说：隐藏在它上面。 grep的code的格式，使这很难看到的。

It is hidden from the SDK because it is only meant to be used internally. That's why it says "Hide:" above it. The format of grepcode makes that hard to see.
