android自定义application

1 继承application

public class CustomApplication extends Application
{
private static final String VALUE = "Harvey";

private String value;

@Override
public void onCreate()
{
super.onCreate();
setValue(VALUE); // 初始化全局变量
}

public void setValue(String value)
{
this.value = value;
}

public String getValue()
{
return value;
}
}

2.在ApplicationManifest.xml文件中配置自定义的Application

<application
        android:name="CustomApplication">
</application>
