在使用mmm单独编译android应用程序时出现如下错误：

“This attribute must be localized”，这种问题一般情况是因为在res/layout下的文件中出现了没有多语言话的文本例如

<Button

android:id="@+id/btnLED1On"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="on"

android:layout_x="8px"

android:layout_y="42px"

>

</Button>

解决办法：

在res/values/strings.xml中定义字符串
<string name="led1on">on</string>

然后再把res/layout/main.xml相应内容改成

<Button

android:id="@+id/btnLED1On"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@sring/led1on"

android:layout_x="8px"

android:layout_y="42px"

>

</Button>

这是android强制实行多语言话，是为了方便应用多言版本的扩充。
