Android 如何获取最顶端的Top Activity, 见如下代码：[java] view plain copypublic static class TopActivityInfo { public String packageName = ""; public String topActivityName = ""; } [java] view plain copyprivate TopActivityInfo getTopActivityInfo() { ActivityManager manager = ((ActivityManager)GlobalConfig.getContext().getSystemService(Context.ACTIVITY_SERVICE)); TopActivityInfo info = new TopActivityInfo(); if (Build.VERSION.SDK_INT >= 21) { List<ActivityManager.RunningAppProcessInfo> pis = manager.getRunningAppProcesses(); ActivityManager.RunningAppProcessInfo topAppProcess = pis.get(0); if (topAppProcess != null && topAppProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) { info.packageName = topAppProcess.processName; info.topActivityName = ""; } } else { //getRunningTasks() is deprecated since API Level 21 (Android 5.0) List localList = manager.getRunningTasks(1); ActivityManager.RunningTaskInfo localRunningTaskInfo = (ActivityManager.RunningTaskInfo)localList.get(0); info.packageName = localRunningTaskInfo.topActivity.getPackageName(); info.topActivityName = localRunningTaskInfo.topActivity.getClassName(); } return info; }

On one hand this paper introduces a workflow meta-model, which is a process-centric integrated multi-view model including the product, the resource, the organization, and the evaluation information. The meta-model is used to guide and constrain the workflow modeling and can be described formally by object constraint language. On the other hand, the architecture of workflow simulation system is explained. ... 工作流仿真是支持过程改进的有效技术。从建模角度介绍了以过程为核心,集成产品、资源、组织和控制评价等信息的工作流元模型。该元模型用来指导和约束具体的工作流建模,可以利用对象约束语言进行深入刻画。从执行角度解释了基于ECA规则的工作流仿真机制。按照Windows DNA三层结构,它分用户界面层、业务逻辑层和数据库层,仿真引擎构建在业务逻辑层。在此基础上就一个软件开发过程的实例,依据过程度量指标,利用仿真结果分析了各种可能的改进方案。 文摘来源 A systems security engineering capability maturity model (SSE-CMM) is used to describe the essential characteristics of an organization's security engineering process to ensure good security engineering. A common question posed in using the SSE-CMM is, how to know if these processes will result in a more secure system or operational capability. To answer this question, this paper approaches the question from two different perspectives using metrics as a basis for the answer.

启动其他APK的Activity方法有两个app,分别叫做App1和App2。App1包含两个Activity,分别叫做App1_A和App1_B.其中App1_A是入口Activity.也就是App1_A设置intent-filter,action为<action android:name="android.intent.action.MAIN" />App2只有一个Activity，叫做App2_A。现在在App2_A中通过startActivity启动App1_A是没问题的.但是启动App1_B的时候报了fc错误。logcat如下:08-03 02:23:44.119: WARN/ActivityManager(64): Permission denied: checkComponentPermission() reqUid=1003008-03 02:23:44.119: WARN/ActivityManager(64): Permission Denial: starting Intent { act=android.intent.action.VIEW cmp=com.hello/.activity2 } from ProcessRecord{407c8bc8 665:com.fileExplorer/10032} (pid=665, uid=10032) requires null用法如下:Intent intent = new Intent(); ComponentName componentName = new ComponentName("com.hello","com.hello.App1_A");//这个没问题 //ComponentName componentName = new ComponentName("com.hello","com.hello.App1_B");//这个报错 intent.setComponent(componentName); startActivity(intent);解决方法:(1)通过隐式intent调用方法实现，需要在被调用的activity的manifest文件中添加<intent-filter><action android:name="com.example.project.SHOW_ACTIVITY" /><category android:name="android.intent.category.DEFAULT" /></intent-filter>在StartActivity(it)之前，设定该intent对应的action(com.example.project.SHOW_ACTIVITY) Intent intent = new Intent();intent.setAction(action);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);context.startActivity(intent);推荐使用利用setAction方法启动Activity还有一个好处就是不需要知道包名和Activity类名，只需要知道action就可以隐式的启动activity(2)即使直接指定了目标activity的ComponentName，跨应用的activity调用也要至少给目标activity指定一个带action的filter。如：<intent-filter><action android:name="" /></intent-filter>action name为空即可。 (3)给被调用的Activity增加一个带action的filter,如下:<intent-filter><action android:name="com.sdmc.ottplayer.uercenter" /></intent-filter>然后可以通过隐式Intent来调用，而不用使用intent.setComponent方法，如下就OK了(但是经过验证，这种方法只是对APK的入口activity有用，对普通的没用,和上面的问题一样无法解决:启动其他APK的非入口activity)Intent i = new Intent("com.sdmc.ottplayer.uercenter");i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);this.startActivity(intent);异常处理:Caused by: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?Context中有一个startActivity方法，Activity继承自Context，重载了startActivity方法。如果使用 Activity的startActivity方法，不会有任何限制，而如果使用Context的startActivity方法的话，就需要开启一个新 的task，遇到上面那个异常的，都是因为使用了Context的startActivity方法。解决办法是，加一个flag。intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)Intent intent = new Intent();intent.setClass(mContext, VideoPlayer.class);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);mContext.startActivity(intent);
