Getting Image from gallery in android

I've been trying to get an image from gallery in this app and then on a button click I want to upload to my PHP server.

The "selectedImagePath" comes as null why?
If anyone has a solutions please help me! Thanks in advance.

onCreate()



img = (ImageView) findViewById(R.id.ImageView01);
Button browse = (Button) findViewById(R.id.Button01);

browse.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
}
});


onActivityResult()



public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
selectedImageUri = data.getData();
System.out.println(selectedImageUri);
selectedImagePath = getPath(selectedImageUri);//returns as null
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}


getPath()



public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
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

try this

@Override
public void onClick(View view) {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    startActivityForResult(intent, 0);
}

@Override
 protected void onActivityResult(int reqCode, int resCode, Intent data) {
    if(resCode == Activity.RESULT_OK && data != null){
        String realPath;
        // SDK < API11
        if (Build.VERSION.SDK_INT < 11) {
            realPath = RealPathUtil.getRealPathFromURI_BelowAPI11(this, data.getData());
        }

        // SDK >= 11 && SDK < 19
        else if (Build.VERSION.SDK_INT < 19) {
            realPath = RealPathUtil.getRealPathFromURI_API11to18(this, data.getData());
        }

        // SDK > 19 (Android 4.4)
        else {
            realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());
        }
        System.out.println("Image Path : " + realPath);
    }
}


public class RealPathUtil {

    @SuppressLint("NewApi")
    public static String getRealPathFromURI_API19(Context context, Uri uri){
        String filePath = "";
        String wholeID = DocumentsContract.getDocumentId(uri);

         String id = wholeID.split(":")[1];

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

         // where id is equal to             
         String sel = MediaStore.Images.Media._ID + "=?";

         Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
                                   column, sel, new String[]{ id }, null);

         int columnIndex = cursor.getColumnIndex(column[0]);

         if (cursor.moveToFirst()) {
             filePath = cursor.getString(columnIndex);
         }   
         cursor.close();
         return filePath;
    }


    @SuppressLint("NewApi")
    public static String getRealPathFromURI_API11to18(Context context, Uri contentUri) {
          String[] proj = { MediaStore.Images.Media.DATA };
          String result = null;

          CursorLoader cursorLoader = new CursorLoader(
                  context, 
            contentUri, proj, null, null, null);        
          Cursor cursor = cursorLoader.loadInBackground();

          if(cursor != null){
           int column_index = 
             cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
           cursor.moveToFirst();
           result = cursor.getString(column_index);
          }
          return result;  
    }

    public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri){
               String[] proj = { MediaStore.Images.Media.DATA };
               Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
               int column_index
          = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
               cursor.moveToFirst();
               return cursor.getString(column_index);
    }
}

the code for getRealPath class is not mine, I din't write down the website.
