android - 无法压缩域。 Realm.getInstance 使我的应用程序在 LG G5 上崩溃

Question

我在尝试运行以下 REALM 代码时遇到此错误。为什么会这样？

代码:

  public static void deleteRealm(Context context) {
    Realm realm = Realm.getInstance(PSApplicationClass.Config);
    try {
        Log.i("", "realm start");
        realm.executeTransaction(new Realm.Transaction() {
            @Override
            public void execute(Realm realm) {
                realm.delete(Destination.class);
                realm.delete(TripStep.class);
                realm.delete(TripStop.class);
                realm.delete(Route.class);
                realm.delete(RealmLocation.class);
                realm.delete(PSTrip.class);
                realm.delete(PSUser.class);
                realm.delete(UserVehicle.class);
                realm.delete(Vehicle.class);
                realm.delete(MileageRates.class);
                realm.delete(PSUserActivityMonth.class);
                realm.delete(PSUserActivityWeek.class);
                realm.delete(PSUserActivityYear.class);
                realm.delete(Activity.class);
                realm.delete(PSTripsStats.class);
            }
        });
        realm.close();
        RealmManager.closeInstance();
        try {
            boolean compact = Realm.compactRealm(PSApplicationClass.Config);
            Log.i("", "GLOBAL realm end: " + compact);
        }catch (Exception e){
            Utils.appendLog("Error trying to compact realm","E", Constants.OTHER);
        }
    } catch (Exception e) {
        Log.i("", "realm continue initTrip error trying to add to realm:" + e.getMessage());
        if (realm.isInTransaction()) {
            realm.cancelTransaction();
        }
    }
}

错误:

这发生在 Realm realm = Realm.getInstance(PSApplicationClass.Config);

这不会发生在 Le Eco Le 2 Pro 或 Nexus 5 上，但会发生在我的 LG G5 上。我压实的方式有问题吗？ (这里还没有达到紧凑的代码，所以我不明白这怎么可能。

经过多次测试和反复试验，我发现了问题所在。注销时，我正在删除数据目录的上下文。所以对于 API > N 的手机会崩溃:

   int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if (currentapiVersion >= android.os.Build.VERSION_CODES.N) {
        FileUtils.deleteQuietly(context.getDataDir());
    }
