Is it really necessary for you to get a physical path? 
For example, <code>ImageView.setImageURI()</code> and <code>ContentResolver.openInputStream()</code> allow you to access the contents of a file without knowing its real path.

blocks|key|1256692|text|这就是我要做的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1256693|Uri+selectedImageURI+=+data.getData();

}|1256696|注意：managedQuery()方法已被弃用，所以我没有使用它。|offset|length|style|CODE|1256697|最后一次编辑:改进。我们应该关闭光标！！|1256698|entityMap^0|0|0|0|0|3|E|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|Y|8|@$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|11|8|@]|9|@]|A|$]]|$1|S|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|T|$]]

This is what I do:

<pre><code>Uri selectedImageURI = data.getData();
imageFile = new File(getRealPathFromURI(selectedImageURI));
</code></pre>

and:

<pre><code>private String getRealPathFromURI(Uri contentURI) {
 String result;
 Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
 if (cursor == null) { // Source is Dropbox or other similar local file path
 result = contentURI.getPath();
 } else { 
 cursor.moveToFirst(); 
 int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
 result = cursor.getString(idx);
 cursor.close();
 }
 return result;
}
</code></pre>

NOTE: <code>managedQuery()</code> method is deprecated, so I am not using it.

Last edit: Improvement. We should close cursor!!

This helped me to get uri from Gallery and convert to a file for Multipart upload

<pre><code>File file = FileUtils.getFile(this, fileUri);
</code></pre>

<a href="https://github.com/iPaulPro/aFileChooser/blob/master/aFileChooser/src/com/ipaulpro/afilechooser/utils/FileUtils.java" rel="nofollow noreferrer">https://github.com/iPaulPro/aFileChooser/blob/master/aFileChooser/src/com/ipaulpro/afilechooser/utils/FileUtils.java</a>

I'm trying to get image from gallery. 

<pre><code>Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select picture"), resultCode );
</code></pre>

After I returned from this activity I have a data, which contains Uri. It looks like:

<pre><code>content://media/external/images/1
</code></pre>

How can I convert this path to real one (just like '<code>/sdcard/image.png</code>') ?

Thanks
