From Android O (API level 26) you can not use getPackageSizeInfo method with reflaction. Following is a code that can help you for both below api level 26 and above it:

private void getPackageSizeInfo(final Context context, String packageName) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        final StorageStatsManager storageStatsManager = (StorageStatsManager) context.getSystemService(Context.STORAGE_STATS_SERVICE);
        final StorageManager storageManager = (StorageManager)  context.getSystemService(Context.STORAGE_SERVICE);
        try {

            ApplicationInfo ai = context.getPackageManager().getApplicationInfo(packageName, 0);
            StorageStats storageStats = storageStatsManager.queryStatsForUid(ai.storageUuid, getApplicationInfo().uid);
            long cacheSize =storageStats.getCacheBytes();
            long dataSize =storageStats.getDataBytes();
            long apkSize =storageStats.getAppBytes();
            Toast.makeText(context, cacheSize + ",," + dataSize + ",," + apkSize, Toast.LENGTH_LONG).show();
            //long size += info.cacheSize;
        } catch (Exception e) {
            e.printStackTrace();
        }
    } else  {
        Method getPackageSizeInfo;
        try {
            getPackageSizeInfo = context.getPackageManager().getClass()
                .getMethod("getPackageSizeInfo",
                    String.class, Class.forName("android.content.pm.IPackageStatsObserver"));

            getPackageSizeInfo.invoke(context.getPackageManager(), packageName,
                new IPackageStatsObserver.Stub() { //error

                    public void onGetStatsCompleted(
                        PackageStats pStats, boolean succeeded)
                        throws RemoteException {

                        //totalSize = totalSize + pStats.cacheSize;
                        //Log.d("size", totalSize+"");
                        Toast.makeText(getApplicationContext(), "size"+pStats.cacheSize + ",," + pStats.dataSize + ",," + pStats.codeSize, Toast.LENGTH_SHORT).show();
                    }
                }
            );
        } catch (Exception e) {
            try {
                getPackageSizeInfo = context.getPackageManager().getClass()
                    .getMethod("getPackageSizeInfo",
                        String.class, Class.forName("android.content.pm.IPackageStatsObserver"));

                getPackageSizeInfo.invoke(context.getPackageManager(), packageName,
                    new IPackageStatsObserver.Stub() { //error

                        public void onGetStatsCompleted(
                            PackageStats pStats, boolean succeeded)
                            throws RemoteException {
                            Toast.makeText(getApplicationContext(), "size"+pStats.cacheSize, Toast.LENGTH_SHORT).show();
                        }
                    }
                );
            } catch (Exception ee) {
                Log.d("eeeeeeeeeee", "error");
                ee.printStackTrace();
            }
        }
    }
}

Please notice that for API level below 26 for making the code work, you should configure AIDL and the requirments according to: https://stackoverflow.com/a/30278018/1939409

Relplace

ApplicationInfo ai = context.getPackageManager().getApplicationInfo(packageName, 0);
StorageStats storageStats = storageStatsManager.queryStatsForUid(ai.storageUuid, getApplicationInfo().uid);
long cacheSize =storageStats.getCacheBytes();
long dataSize =storageStats.getDataBytes();
long apkSize =storageStats.getAppBytes();
Toast.makeText(context, cacheSize + ",," + dataSize + ",," + apkSize, Toast.LENGTH_LONG).show();
//long size += info.cacheSize;

with

ApplicationInfo ai = AppController.getContext().getPackageManager().getApplicationInfo(packageName, 0);
StorageStats storageStats = storageStatsManager.queryStatsForUid(ai.storageUuid, AppController.getContext().getApplicationInfo().uid);
long cacheSize = storageStats.getCacheBytes();
long dataSize = storageStats.getDataBytes();
long apkSize = storageStats.getAppBytes();

PackageStats packageStats = new PackageStats(packageName);
packageStats.cacheSize = cacheSize;
packageStats.dataSize = dataSize;
packageStats.codeSize = apkSize;
observer.onGetStatsCompleted(packageStats, true);
