java.lang.IllegalArgumentException : Unknown URL file at android. content.ContentResolver.delete

Question

出现上述错误

builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
                    @Override
                    public void onCancel(DialogInterface dialog) {

                        if (mImageCaptureUri != null)
                        {
                            //exception at below line
                            getContentResolver().delete(mImageCaptureUri, null,null);
                            mImageCaptureUri = null;
                        }
                    }
                });

我尝试通过 new File(mImageCaptureUri.getPath()).exists() 检查文件是否存在它存在，但我仍然收到异常

java.lang.IllegalArgumentException: Unknown URL file:///storage/sdcard0/tmp_avatar_1412858553212.jpg    
at android.content.ContentResolver.delete(ContentResolver.java:984) 

Answer 1

I tried checking if file exists by new File(mImageCaptureUri.getPath()).exists() it exists

请注意 there is no requirement that a Uri point to a file that you can access .

still i'm getting the exception as

java.lang.IllegalArgumentException: Unknown URL file:///storage/sdcard0/tmp_avatar_1412858553212.jpg at android.content.ContentResolver.delete(ContentResolver.java:984) 

ContentResolver 主要用于 content:// 方案。对于 file:// 方案，您可能需要尝试自己直接删除文件。
