手机无法使用debug的解决方法

描述：
用Nexus one debug，报错：
Device 'device_name' requires that applications explicitely
declare themselves as debuggable in their manifest.
Application 'com.prj.test01' does not have the attribute
'debuggable' set to TRUE in its manifest and cannot be debugged


解决方法：
<application android:icon="@drawable/icon"
  android:label="@string/app_name"
  android:debuggable="true">
