android - gralloc_goldfish(634) : Emulator without GPU emulation detected

Question

我正在使用 android SDK 4.0.3，我正在尝试运行一个简单的程序，在该程序中，我尝试使用 Intent 从一个页面切换到另一个页面(通过将 intent 对象传递为:Intent intent = new Intent (getApplicationContext(),SecondActivity.class);启动 Activity ( Intent )； )

[另外，我有 3GB RAM]

但是当我运行程序时，它在 DDMS 中给出了类似这样的内容:

Answer 1

如果您担心:

Emulator without GPU emulation detected.

我不会。鉴于粗略地搜索一下网络，结果相当多，而且它与正在讨论的具体问题无关，我想说这只是表明您的模拟器根本不模拟 GPU。这不太可能成为问题。

事实证明这是一条调试消息(甚至不是警告，更不用说错误了)，而且这与您的实际问题之间存在 42 秒的巨大差距。

实际问题似乎由以下行指示:

01-23 01:58:45.532: E/AndroidRuntime(634):
    android.content.ActivityNotFoundException: Unable to find explicit activity
    class {com.example.actionbar_demo/com.example.actionbar_demo.SecondActivity};
    have you declared this activity in your AndroidManifest.xml?

所以我不得不问:您是否在 AndroidManifest.xml 中声明了此 Activity ？
