Androidプログラムでアプリケーションに費やされた時間を取得する方法

今日使用したすべてのアプリケーションの使用時間を取得したい。

*#*#4636#*#*をダイヤルすると、これらの詳細が表示されます。しかし、私はこれらの詳細をAndroidでプログラム的に必要としています。これで私を助けてください。

これらのPlayストアアプリが使用統計を表示する方法を確認できます

[〜＃〜] tldr [〜＃〜] @chand_becseコードを使用し、リストが空の場合は、このreguestPermissionsメソッドを追加し、onCreateでこれを呼び出しますメソッド（UsageStatsManagerが初期化された直後）

Chand becseの回答は完全に有効ですが、アプリケーションには他のアプリの統計情報を使用する権限が必要であることを覚えておく必要があります。 permision.PACKAGE_USAGEは単にユーザーに要求することはできないので、ACTION_USAGE_ACCESS_SETTINGSビューにリダイレクトして、手動でこれらの権限をオンにする必要があります。また、アプリケーションがすでにパーミッションを取得しているかどうかを確認するときに（すでに取得している場合でも）-1を取得するたびに、statsリストを確認していることにも気付きました。空です。もしそうなら、私は私のアプリケーションがこの機能のための許可を必要としていると思います。

    private void requestPermissions() {
        List<UsageStats> stats = mUsageStatsManager
                .queryUsageStats(UsageStatsManager.INTERVAL_DAILY, 0, System.currentTimeMillis());
        boolean isEmpty = stats.isEmpty();
        if (isEmpty) {
            startActivity(new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS));
        }
    }
