Java cursor error – retrieve image from Gallery

At present, I am trying to retrieve the location of the image in the gallery and convert it into a file so that it can be uploaded to the Internet. But I received this error. An error occurred when I opened the gallery and selected the image. I am not proficient in Android and still think I am a beginner. Therefore, if you decide to refuse my question, please tell me the reason so that I can learn. Thank you

The code I use to retrieve the image is as follows:

 private String getRealPathFromURI(Uri contentURI) {
    String result;
    Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
    if (cursor == null) { // Source is Drop@R_613_2419@ or other similar local file path
        result = contentURI.getPath();
    } else {
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
        result = cursor.getString(idx); // getting error here ; it returns -1
        cursor.close();
    }
    return result;
}

resolvent:

You must add the column name mediastore.images.media.data to the query

Update getrealpathfromuri () as follows:

private String getRealPathFromURI(Uri contentURI) {

    String result;
    String[] filePathColumn = { MediaStore.Images.Media.DATA };        

    Cursor cursor = getContentResolver().query(contentURI, filePathColumn, null, null, null);
    if (cursor == null) { // Source is Drop@R_613_2419@ or other similar local file path
        result = contentURI.getPath();
    } else {
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(filePathColumn[0]);
        result = cursor.getString(idx);
        cursor.close();
    }
    return result;
}

In your onactivityresult() method:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        // When an Image is picked
        if (requestCode == YOUR_REQUEST_CODE && resultCode == RESULT_OK
                && null != data) {
            // Get the Image from data
            Uri selectedImage = data.getData();

            // Get real path 
            String imageRealPath = getRealPathFromURI(selectedImage);

            // Do something

        }
    } catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                .show();
    }

}

Make sure you have added permissions:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

This is a good tutorial. I hope it will help ~
