记录开发中常出现的错误
1、遇到这样的错误时，应该立马想到是书写错误或语法错误，常见为android:name写成了name
Attribute is missing the Android namespace prefix
2、解决：菜单：project->clean。
Activity not started, its current task has been brought to the front
3、可能是title的冲突，解决：AndroidManifest.xml下的android:theme="@android:style/xx" 修改下其他样式
android.util.AndroidRuntimeException: You cannot combine custom titles with other title
4、解决：Context改为自己的Activity.this
The method makeText(Context, CharSequence, int) in the type Toast is not applicable for the arguments (new View.OnClickListener(){}, String, int)
