gralloc_goldfish(634):未检测到GPU仿真的仿真器

Question

我使用的Android SDK 4.0.3,我试图运行在我试图从一个页面切换到使用一个Intent另一个页面的简单程序(通过传递意图对象为:意向意图=新意图(getApplicationContext( ),SecondActivity.class); startActivity(intent);)

[另外,我有3GB内存]

但是当我运行程序时,它在DDMS中给出了类似的东西:

01-23 01:58:23.892: D/gralloc_goldfish(634): Emulator without GPU emulation detected.

Answer 1

如果你担心:

Emulator without GPU emulation detected.

我不会.鉴于对网络的粗略搜索使其变得相当多,并且它与所讨论的具体问题无关,我认为这只是表明您的模拟器根本不模拟GPU.这不太可能是个问题.

这是因为它是一个调试消息(甚至不是警告,更不用说是一个错误),而且它和你的实际问题之间存在42秒的差距.

在实际的问题似乎是由线来表示:

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,我要问:有你宣布你的AndroidManifest.xml这个活动？
