我正在創(chuàng)建一個(gè)應(yīng)用鎖定應(yīng)用程序。如何在棒棒糖中獲取當(dāng)前正在運(yùn)行的任務(wù)？getRunningTaskinfo棒棒糖API中已棄用該方法，那么如何解決此問(wèn)題？

在API 21或更高版本中獲取“運(yùn)行應(yīng)用”的最佳解決方案是嘗試以下方法。這項(xiàng)工作對(duì)我來(lái)說(shuō)
private String retriveNewApp() {
if (VERSION.SDK_INT >= 21) {
String currentApp = null;
UsageStatsManager usm = (UsageStatsManager) this.getSystemService(Context.USAGE_STATS_SERVICE);
long time = System.currentTimeMillis();
List<UsageStats> applist = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time);
if (applist != null && applist.size() > 0) {
SortedMap<Long, UsageStats> mySortedMap = new TreeMap<>();
for (UsageStats usageStats : applist) {
mySortedMap.put(usageStats.getLastTimeUsed(), usageStats);
}
if (mySortedMap != null && !mySortedMap.isEmpty()) {
currentApp = mySortedMap.get(mySortedMap.lastKey()).getPackageName();
}
}
Log.e(TAG, "Current App in foreground is: " + currentApp);
return currentApp;
}
else {
ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
String mm=(manager.getRunningTasks(1).get(0)).topActivity.getPackageName();
Log.e(TAG, "Current App in foreground is: " + mm);
return mm;
}
}
