为什么Android Emulator会在黑屏上闪烁Android？

Question

我已经安装了Eclipse Helios和Android Sdk。 问题是，当我启动模拟器时，黑屏上闪烁着android文本。 我在日志中收到以下错误。任何人都可以提出逐步解决此问题的建议。 错误如下：

Answer 1

创建模拟器时，请检查底部的“使用主机GPU”选项

Answer 2

“闪烁的Android文本”表示仿真器正在启动。 这可能需要一段时间，具体取决于计算机的速度。

有时它只是卡住了，您必须删除它并重新开始，但这听起来您已经尝试过了。

从Eclipse启动仿真器时，请查看“控制台”选项卡，而不是“日志”选项卡。 控制台可能会显示错误消息。 日志标签仅显示logcat，这是来自Android本身的消息

当您创建新的仿真器时，如果您尝试超过768M，它将警告您分配过多的RAM，根据虚拟设备设置底部的错误消息，仿真器可能无法启动。 请尝试使用512M RAM，看看它是否启动。

Answer 3

我发现了同样的问题。 相同的错误消息会一遍又一遍地循环显示。 当我将仿真器升级到API版本19时会发生这种情况。（我等了一夜，但仿真器从未启动。）

但是，如果我使用API​​版本17运行仿真器，则大约五分钟后它就可以正常启动。 （顺便说一句，我两次分配了512兆。）
