这里只演示了Activity,BroadcastReceiver,Service的禁用和启用，没有演示ContentProvider,道理都一样。
/**
* @author Administrator
* 通过PackageManager的setComponentEnabledSetting()方法，实现四大组件(Activity,BroadcastReceiver,Service,ContentProvider)的禁用和启用.
* 在PackageManager中定义的四大组件的三种基本状态有：
* COMPONENT_ENABLED_STATE_ENABLED：组件可用
* COMPONENT_ENABLED_STATE_DISABLED:组件不可用
* COMPONENT_ENABLED_STATE_DEFAULT:默认，即你清单文件中组件的默认状态。
* 可通过PackageManager的getComponentEnabledSetting(ComponentName componentName)方法获取组件的当前状态；
* 可通过PackageManager的setComponentEnabledSetting(ComponentName componentName,int newState, int flags)方法设置组件的状态
* 需要注意的是，当设置app的LAUNCHER Activity的状态为COMPONENT_ENABLED_STATE_DISABLED时，即为隐藏该app在桌面的图标，但是在设置>application选项里
* 仍然可看到该activity存在
