SDK2.3适用的判断当前是否Launcher的方法

记录一下，如何判断当前activity是否launcher的准确的办法？

错误方式：getRunningTasks --- 

private boolean isHome() {
ActivityManager mActivityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningTaskInfo> taskInfoList = mActivityManager.getRunningTasks(1);
if (taskInfoList == null || taskInfoList.isEmpty()) {
return false;
}
return getHomes().contains(taskInfoList.get(0).topActivity.getPackageName());
}

正确方式：getRunningAppProcesses --- 

public boolean isHome() {
ActivityManager activityManager = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
return getHomes().contains(appProcess.processName);
}else{
return true;
}
}
return false;
}

公共部分代码：
private List<String> getHomes() {
List<String> names = new ArrayList<String>();
PackageManager packageManager = mContext.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
List<ResolveInfo> resolveInfo = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo ri : resolveInfo) {
if ("com.kitsmart.setupwizard".equals(ri.activityInfo.packageName))
continue;
names.add(ri.activityInfo.packageName);
}
return names;
}
