Get filepath and filename of selected gallery imag

Question

I am creating an app which uploads a selected image from the gallery and uploads it to a web service. The webservice requires the filename of selected image plus a base64 encoding of the file contents. I have managed to achieve this with a hardcoded file path. However, I am struggling to get the real filepath of the image. I have read around the web and have this code, but it does not work for me:

 public void onActivityResult(int requestCode, int resultCode, Intent data) {
   if (resultCode == RESULT_OK) {
     Uri selectedImageUri = data.getData();
     String[] projection = {MediaStore.Images.Media.DATA};

     try {
       Cursor cursor = getContentResolver().query(selectedImageUri, projection, null, null, null);
       cursor.moveToFirst();

       int columnIndex = cursor.getColumnIndex(projection[0]);
       String picturePath = cursor.getString(columnIndex);
       cursor.close();
       Log.d("Picture Path", picturePath);
     }
     catch(Exception e) {
       Log.e("Path Error", e.toString());
     }
   }
 }

I get this error:

java.lang.NullPointerException

EDIT

Forgot to mention I am using Kitkat. It looks like my problem is KitKat related. I found this (see below) which helped me get my app working:

Android Gallery on KitKat returns different Uri for Intent.ACTION_GET_CONTENT

Answer 1

Try this:

Uri selectedImageURI = data.getData();
imageFile = new File(getRealPathFromURI(selectedImageURI));

And

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

Answer 2

Try this,

 file = new File(getPath(outputFileUri));


 public String getPath(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    @SuppressWarnings("deprecation")
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Answer 3

Use below code,

public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (resultCode == RESULT_OK) {

     Uri selectedImageUri = data.getData();
     String s = getRealPathFromURI(selectedImageUri);
     editText1.setText(s);
}
}

and below is your getRealPathFromURI function,

public String getRealPathFromURI(Uri uri) {
    String[] projection = { MediaStore.Images.Media.DATA };
    @SuppressWarnings("deprecation")
    Cursor cursor = managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Hope this helps you

 if (Build.VERSION.SDK_INT <19){

    Intent intent = new Intent(); 
    intent.setType("image/jpeg");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, 
    getResources().getString(R.string.select_picture)),GALLERY_INTENT_CALLED);

 }else{

      Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
      intent.addCategory(Intent.CATEGORY_OPENABLE);
      intent.setType("image/jpeg");
      startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
 }

 @Override
 public void onActivityResult(int requestCode, int resultCode, Intent data)
 {

      super.onActivityResult(requestCode, resultCode, data);
      if (resultCode != Activity.RESULT_OK) return;
      if (null == data) return;
      Uri originalUri = null;

      if (requestCode == GALLERY_INTENT_CALLED) {
           originalUri = data.getData();
      } 
      else if (requestCode == GALLERY_KITKAT_INTENT_CALLED) {
           originalUri = data.getData();
           final int takeFlags = data.getFlags()
            & (Intent.FLAG_GRANT_READ_URI_PERMISSION
            | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

            // Check for the freshest data.
            getContentResolver().takePersistableUriPermission(originalUri,    takeFlags);
      }
      loadSomeStreamAsynkTask(originalUri);
}

Answer 5

If you are like me and you dont have a local file ready, for instance you want to give user a chance to take a picture and then upload the picture this is how to do it. I am a noob in java but i have allot of experience in coding. Stackoverflow helped me allot so now it is my time to do something back.

Under class activity you have to declare these two items. asuming you have a working upload class and php script.

NOTE i am not taking any consideration about all the different API's out there. I am using java compiler 1.7 and a API range of 10 to 18.

public class Yourproject extends Activity {
File imageFile;
File imageFileName;

//This part is needed for decoding the path adres.

 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.BUCKET_DISPLAY_NAME); 
                result = cursor.getString(idx);
                cursor.close();
            }
            return result;
        }

//This is needed for the path name, now you might just want to use one decoding script depending on //your class in total.
//In my case this was the way to go.
//To use one single addres use this line ImageColumns.DATA in the int idx declaration.

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

//Then under protected void onCreate(Bundle savedInstanceState) you place this code to get 
//the image and process it.
@Override
protected void onCreate(Bundle savedInstanceState) {
        //declare the ImageView
        final ImageView inputPicture = (ImageView) findViewById(R.id.imageView2);

        inputPicture.setImageURI((Uri) getIntent().getExtras().get("picture"));
        //here where recieve the image from last page "Putextra" method


        try {
            //here we will get the data and proces it trough to get the real 
            //address for uploading.
            //This is send from a other activity with a Intent.EXTRA_STREAM
            //The code looks like this:
            /*********"Putextra"*********/
            //final ImageView iv = (ImageView) findViewById(R.id.imageView1);
            //final Uri thumb = (Uri) getIntent().getExtras().get(Intent.EXTRA_STREAM);
            //iv.setImageURI(thumb);

            //Sending it to the next activity

            //it.putExtra("picture", thumb);    
            /*********"Putextra"*********/

            Uri fileUri = (Uri) getIntent().getExtras().get("picture");
            //get 
            //Uri fileName = (Uri) getIntent().getExtras().get("picture");
            //get
            imageFile = new File(getRealPathFromURI(fileUri));
            //send
            imageFileName = new File(getRealPathFromNAME(fileUri));
            //send
            //i got a exeption Uri fileName, use fileUri twice..
        } catch (Exception e2) {
            // TODO Auto-generated catch block
            e2.printStackTrace();
        }
        //here we will declare the name for furter processing.
        final File uploadFilePath = imageFile;
        final File uploadFileName = imageFileName;


}

And the rest i will leave up to u, if you got this far, I am pretty sure you will finish.

Answer 6

A little late to the party but here's my code, hope this helps.

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        Uri selectedImageUri = data.getData( );
        String picturePath = getPath( getActivity( ).getApplicationContext( ), selectedImageUri );
        Log.d("Picture Path", picturePath);
    }
}

public static String getPath( Context context, Uri uri ) {
    String result = null;
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver( ).query( uri, proj, null, null, null );
    if(cursor != null){
        if ( cursor.moveToFirst( ) ) {
            int column_index = cursor.getColumnIndexOrThrow( proj[0] );
            result = cursor.getString( column_index );
        }
        cursor.close( );
    }
    if(result == null) {
        result = "Not found";
    }
    return result;
}
