How to rename File From filepath in Android?

Question

I have Path Which is stored into one variable That is

String Path:

String filepath="/mnt/sdcard/DCIM/Camera/1396854069062.jpg";

Now i want to rename only file that is 1396854069062.jpg I Reilly don't have any idea for how to do that.

My Code Is:

File sdcard = Environment.getExternalStorageDirectory();
File from = new File(sdcard, filePath);
File to = new File(sdcard, "RChat_Rename.jpg";
from.renameTo(to);

Any help will b appreciated.

Thank You

@InnocentKiller answer is perfect +1 for that..@Nirav Dabhi have you added READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions? — TheFlash, Apr 07 '14 at 11:29

Try this way,

File sdcard = Environment.getExternalStorageDirectory();
File from = new File(sdcard,"/1396854069062.jpg");
File to = new File(sdcard,"test.jpg");
from.renameTo(to);

Do not forget to add below permission in android manifest file

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

Edit

String filepath= Environment.getExternalStorageDirectory() + "/DCIM/Camera/";
File from = new File(filepath,"1396854069062.jpg");
File to = new File(filepath,"test.jpg");
from.renameTo(to);

Don't forget to add accessing SD card permission in manifest @NiravDabhi other wise it won't work – AlphaCode Apr 07 '14 at 11:27

Have you added `` this permission in manifest. – InnocentKiller Apr 07 '14 at 11:27
Yes I had added the permission but the Result is same – Nirav Dabhi Apr 07 '14 at 11:28
No just file didnt renamed – Nirav Dabhi Apr 07 '14 at 11:29
Are you using the method within "try catch" or alone ? – AlphaCode Apr 07 '14 at 11:30
Indeed it does and if it doesn't show you an error like NullPointException then it's not something related to the code that innocentkiller posted – AlphaCode Apr 07 '14 at 11:32
Yes please see my code in the question My method is in try catch block. – Nirav Dabhi Apr 07 '14 at 11:32
Okey in that case if the code didn't work it will not show the error because it's try . I'm not an expert but can you try using it without try catch and then give us the error log that you get on LogCat ? – AlphaCode Apr 07 '14 at 11:33
@NiravDabhi What does renameTo() return when you run it?? true or false?? – Naveen Apr 07 '14 at 11:34
I think Hamid got it because in this answer you didn't access the "/DCIM/Camera/" folder . Try Hamid's code and tell us what's the result – AlphaCode Apr 07 '14 at 11:36
Acctully my whole path store in the variable. which means when i capture image that should be not the system name. – Nirav Dabhi Apr 07 '14 at 11:36
@NiravDabhi, take a `String` variable instead of `File` for getting SDcard path and then try. – InnocentKiller Apr 07 '14 at 11:42
@NiravDabhi, Still it is the same? Update me whether it is working or not. – InnocentKiller Apr 07 '14 at 11:46
Yes dude its still same. But +1 for your effort. FilePath is dynamic means it is not fixed that user will Pick the image from Camera only. Then how can i do that? – Nirav Dabhi Apr 07 '14 at 12:09
Then you have to use `onActivityResult` and return a path from there and then apply this rename. – InnocentKiller Apr 07 '14 at 12:16
@NiravDabhi, you want to rename last captured image every time, Is this you want to say? – InnocentKiller Apr 07 '14 at 12:18
@NiravDabhi, what i am asking is you want to get the path of last captured image everytime right? Is this what you are asking? – InnocentKiller Apr 07 '14 at 12:36
Yes You are right I want path of last captured image – Nirav Dabhi Apr 07 '14 at 12:42
Okay, for that you have to use `onActivityResult` as i already told you and use `Uri audioUri = data.getData(); String absolutepath = getRealPathFromURI(audioUri);` this inside it. – InnocentKiller Apr 07 '14 at 12:47

So, you want rename a picture which is taken from camera, right? – Hamid Shatu Apr 07 '14 at 12:15
then you should give a name to the image to when you start the camera to capture that image. – Hamid Shatu Apr 07 '14 at 12:23
