When I choose some pictures，it may happen，how can i fix it？

at id.zelory.compressor.ImageUtil.getScaledBitmap(ImageUtil.java:62) actualWidth = bitmap2.getWidth();

java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

I meet the same problem,as well

@yliang11,@yuhaodev this error occur because the application does not have permission to access the image. In my case it worked just by asking for permission in runtime !

@IgorHorta it's not the problem of permission, not every picture can happen，some picture will happen,but some not.I dont know why

I have the same problem. For some pictures it's working but for some I get error. Even when I have permissions when calling compressToFile I get

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

Also in logs I see

@IgorHorta I also have the same problem.When called setDestinationDirectoryPath() method, I set to my source file path as a result path that is setDestinationDirectoryPath(sourceFilePath) ,so I meet this error.

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference at id.zelory.compressor.ImageUtil.decodeSampledBitmapFromFile(ImageUtil.java:70) at id.zelory.compressor.ImageUtil.compressImage(ImageUtil.java:33) at id.zelory.compressor.Compressor.compressToFile(Compressor.java:60) at id.zelory.compressor.Compressor.compressToFile(Compressor.java:56)

This happens when you set the destination directory same as that of the original image file. A work-around is to set a different directory for the compressed image.

How fix?

@hkk565 I want set the same destination directory so that to cover the old image.How to fix this bug?Thanks

@lilealyh I don't recommend you overwriting the original image directly. Because if the compression process somehow fails in the middle, the original image will be destroyed as well. If you have to do this, a work-around is to generate the compressed image file at a different temporary directory first (such as the external cache directory). When it's done, delete the original image file and move the compressed image file to the original directory (using Android I/O APIs).

.setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory( Environment.DIRECTORY_PICTURES).getAbsolutePath())
this method save the image into internal storage and Compressor class does not support this format so u have to store as a temporary into internal storage .i hope its useful for u. thank you

Solution:the reason is that you save your compressed file in the same folder and name with original image, just use compressToFile(File imageFile, String compressedFileName) to set a different name with the original image.

I have same issue. I had use "compressToFile(File imageFile, String compressedFileName) to set a different name with the original image." but the error continues

private File compressImageAnotherLibrary(int width, int height, int quality, File file) {

      try {
          return new Compressor(mContext)
                  .setQuality(quality)
                  .setMaxWidth(width)
                  .setDestinationDirectoryPath(new FileOperations().createMediaFile(Message.messageType.image.toString(), imageExtension, false).getAbsolutePath())
                  .setMaxHeight(height)
                  .setCompressFormat(Bitmap.CompressFormat.JPEG)
                  .compressToFile(file);

      } catch (IOException e) {
          Mylog.printStackTrace(TAG + "compressImageAnotherLibrary error ", e);

          return null;
      }
  }

Please help me!!

I have this error! how can i fix it?

How con I fix this error? I don't know how to continue with the compressor

If it helps anyone else, I get the error when I try to compress an empty file. My solution was to check the file size before invoking the compression library (and also investigate why I my app has empty files in the first place):

if(photoFile != null && photoFile.length() > 0){
    File compressed = new Compressor(this).compressToFile(photoFile);
}

Using the same directory between original and compressed was my cause of this error. Would be nice to see a proper error instead of this one that doesn't really help.

Thank you for the people that mentioned that option!

Choiced the output image to compress was my cause of this error. I resolve this problem with delete the output image after using it.

Hi Guys add image temp file storage it's working fine

private void openCamera() throws IOException { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); photoFile = createImageFile(); photoURI = FileProvider.getUriForFile(getActivity(), getActivity().getPackageName() + ".provider", photoFile); intent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(getActivity(), getActivity().getPackageName() + ".provider", photoFile)); startActivityForResult(intent, IMAGE_CAPTURE_CODE); } private File createImageFile() throws IOException { // Create an image file name File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES); image = File.createTempFile( "temp", /* prefix / ".jpg", / suffix / storageDir / directory */ ); // Log.e(TAG, "createImageFile: "+image.getAbsolutePath() ); mImageFileLocation = image.getAbsolutePath(); if (image.exists()) { image.delete(); } return image; }

BitmapFactory.Options bmOptions = new BitmapFactory.Options(); bmOptions.inJustDecodeBounds = true; BitmapFactory.decodeFile(mImageFileLocation, bmOptions); int cameraImageWidth = bmOptions.outWidth; int cameraImageHeight = bmOptions.outHeight;

        int scaleFactor = Math.min(cameraImageWidth / targetImageViewWidth, cameraImageHeight / targetImageViewHeight);
        bmOptions.inSampleSize = scaleFactor;
        bmOptions.inJustDecodeBounds = false;
        Bitmap photoReducedSizeBitmp = BitmapFactory.decodeFile(mImageFileLocation, bmOptions);

       /* BitmapFactory.Options options = new BitmapFactory.Options();
        options.inPreferredConfig = Bitmap.Config.ARGB_8888;
        Bitmap photoReducedSizeBitmp = BitmapFactory.decodeFile(mImageFileLocation, options);

*/

        try {
            compressedImageFile = new Compressor(Objects.requireNonNull(getActivity())).compressToFile(new File(mImageFileLocation));

        } catch (IOException e) {
            e.printStackTrace();
        }

我的方式

1.    compileOnly "androidx.exifinterface:exifinterface:1.3.2"
2.    replace `android.media.ExifInterface` with `androidx.exifinterface.media.ExifInterface`
