How to solve Error: This attribute must be localized. 两种方式

Best practice for Android apps is to define all of the non-dynamic content in resource files. This lets you define different resource files for different languages, for example. Normally, this is just a recommendation and the Android SDK doesn't complain if you hard-code values in your layout xml. The Android source build system, however, requires that all strings be defined in a "values" resource. This is probably intended to protect system builders from accidentally leaving content in a system image that won't display in the user's chosen language.

What you need to do is move those string values out of the layout and define them in res/values/instead. The usual place for string values is in res/values/strings.xml, but the actual file can be named anything you like as long as it's in that directory.

For example, in res/values/string.xml:

<stringname="topLeftContent">TOP_LEFT</string>

And in your main.xml layout, refer to the content by name:

    android:text="@string/topLeftContent"

For more details on the how and why of this, see Google's documentation on Localization in Android.

You can use

LOCAL_MODULE_TAGS := tests

in the Android.mk to omits the localization check.

Another way is to disable localization check in build system. Comment the line 81 inbuild/core/package.mk

#LOCAL_AAPT_FLAGS := $(LOCAL_AAPT_FLAGS) -z
