gralloc_goldfish(634): Emulator without GPU emulation detected

问题

I am using android SDK 4.0.3 and I'm trying to run a simple program in which I'm trying to switch from one page to another page using an Intent (By passing intent object as: Intent intent = new Intent(getApplicationContext(),SecondActivity.class); startActivity(intent); )

[Also, I have 3GB RAM]

but when I run the program it gives something like this in DDMS:

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

回答1:

If you're worried about the:

Emulator without GPU emulation detected.

I wouldn't be. Given that a cursory search of the net turns it up quite a bit, and it's not related to the specific problems being discussed, I'd say it's just an indication that your emulator simply doesn't emulate the GPU. It's unlikely to be a problem.

That's supported by the fact it's a debug message (not even a warning, let alone an error) and also that there's a big 42-second gap between that and your actual problem.

The actual problem seems to be indicated by the line:

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?

So I have to ask: have you declared this activity in your AndroidManifest.xml?

回答2:

Open the Android Manifest.XML and define {SecondActivity} as a new activity then Eclipse will be able to locate it as a new activity
