android 5.0.2和5.0.1之间有所不同

Question

我只是想知道android 5.0.1和5.0.2之间有什么不同。 因为我的应用程序在5.0.2中运行完美但我在android 5.0.1中有问题。

在我的代码中查看我在if子句中检查设备的版本，但它无法从5.0.1识别5.0.2。

 public static Bitmap downSampleBitmap(Uri uri, Activity act, Boolean needRotate) {
    DisplayMetrics displaymetrics = new DisplayMetrics();
    act.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    Resources r = act.getResources();
    int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
            50, r.getDisplayMetrics()); // 50: magic num
    int targetWidth = displaymetrics.heightPixels;
    int targetHeight = displaymetrics.widthPixels - px;

    Bitmap resizedBitmap = decodeSampledBitmap(uri, targetWidth, targetHeight, act);
    Bitmap returnBitmap = null;
    ExifInterface exif;
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP  && Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP) {
        try {
            exif = new ExifInterface(uri.toString());
            int orient = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
            rotateBitmap(returnBitmap,orient);
            returnBitmap = returnBitmap == null ? resizedBitmap : returnBitmap;
        } catch (IOException e) {
            Log.v(TAG, "not found file at downsample");
            e.printStackTrace();
        }

    } else {
        try {
            float degree = 0;
            exif = new ExifInterface(uri.toString());
            int orient = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
            if (resizedBitmap != null && needRotate) {
                degree = getDegree(orient);
                if (degree != 0) {
                    returnBitmap = createRotatedBitmap(resizedBitmap, degree);
                }
                returnBitmap = returnBitmap == null ? resizedBitmap : returnBitmap;
            }
        } catch (IOException e) {
            Log.v(TAG, "not found file at downsample");
            e.printStackTrace();
        }
    }
    return returnBitmap;
}
