Android NullPointerException異常複製exif標記

我試圖重新調整大小的圖像，該部分完成。然後我試圖將exif標籤複製到新文件中。我使用ExifInterface來讀取標籤。我知道這是一個界面，而不是一個對象。但是當我嘗試使用它來拍攝真正大尺寸的圖像時，我得到了NullPointerException。我得到這個錯誤不是所有的圖像。Android NullPointerException異常複製exif標記

07-25 11:59:23.870: WARN/System.err(1362): java.lang.NullPointerException 
07-25 11:59:23.870: WARN/System.err(1362):  at android.media.ExifInterface.saveAttributes(ExifInterface.java:202)

我該如何解決？

代碼複製EXIF信息

try { 
    // copy paste exif information from original file to new 
    // file 
    ExifInterface oldexif = new ExifInterface(filePath); 
    ExifInterface newexif = new ExifInterface(file.getPath()); 

    int build = Build.VERSION.SDK_INT; 

    // From API 11 
    if (build >= 11) { 
     newexif.setAttribute("FNumber", 
       oldexif.getAttribute("FNumber")); 
     newexif.setAttribute("ExposureTime", 
       oldexif.getAttribute("ExposureTime")); 
     newexif.setAttribute("ISOSpeedRatings", 
       oldexif.getAttribute("ISOSpeedRatings")); 
    } 
    // From API 9 
    if (build >= 9) { 
     newexif.setAttribute("GPSAltitude", 
       oldexif.getAttribute("GPSAltitude")); 
     newexif.setAttribute("GPSAltitudeRef", 
       oldexif.getAttribute("GPSAltitudeRef")); 
    } 
    // From API 8 
    if (build >= 8) { 
     newexif.setAttribute("FocalLength", 
       oldexif.getAttribute("FocalLength")); 
     newexif.setAttribute("GPSDateStamp", 
       oldexif.getAttribute("GPSDateStamp")); 
     newexif.setAttribute("GPSProcessingMethod", 
       oldexif.getAttribute("GPSProcessingMethod")); 
     newexif.setAttribute("GPSTimeStamp", 
       oldexif.getAttribute("GPSTimeStamp")); 
    } 
    newexif.setAttribute("DateTime", 
      oldexif.getAttribute("DateTime")); 
    newexif.setAttribute("Flash", oldexif.getAttribute("Flash")); 
    newexif.setAttribute("GPSLatitude", 
      oldexif.getAttribute("GPSLatitude")); 
    newexif.setAttribute("GPSLatitudeRef", 
      oldexif.getAttribute("GPSLatitudeRef")); 
    newexif.setAttribute("GPSLongitude", 
      oldexif.getAttribute("GPSLongitude")); 
    newexif.setAttribute("GPSLongitudeRef", 
      oldexif.getAttribute("GPSLongitudeRef")); 

    // You need to update this with your new height width 
    newexif.setAttribute("ImageLength", 
      oldexif.getAttribute("ImageLength")); 
    newexif.setAttribute("ImageWidth", 
      oldexif.getAttribute("ImageWidth")); 

    newexif.setAttribute("Make", oldexif.getAttribute("Make")); 
    newexif.setAttribute("Model", oldexif.getAttribute("Model")); 
    newexif.setAttribute("Orientation", 
      oldexif.getAttribute("Orientation")); 
    newexif.setAttribute("WhiteBalance", 
      oldexif.getAttribute("WhiteBalance")); 

    newexif.saveAttributes(); 

    Toast.makeText(getApplicationContext(), 
      "Image resized & saved successfully", 
      Toast.LENGTH_SHORT).show(); 
} catch (Exception e) { 
    e.printStackTrace(); 
}
