Question

In my app I am capturing an image and uploading it to the server. The capturing and uploading part works fine in my Android device which is of 5 mega pixel.

But the app crashes occasionally when taking a photo. We’ve noticed if someone takes a
picture that has a high megapixel setting, the photo does not upload and the app crashes.

How to reduce the size of a 8 megapixel photo to be able to upload without crashing?
Do I have to compress the captured image. Following is my code to capture an image

ContentValues values = new ContentValues();  
values.put(MediaStore.Images.Media.TITLE,fileName);  
mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);          
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  
intent.putExtra(MediaStore.ACTION_IMAGE_CAPTURE, capturedImage);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);  
startActivityForResult(intent, 3);

I am uploading the image in OnActivity Result as follows

public void onActivityResult(int requestCode, int resultCode, final Intent data) 
{
  super.onActivityResult(requestCode, resultCode, data);
  if (requestCode == 3) 
  {     
    String[] projection = { MediaStore.Images.Media.DATA};  
    Cursor cursor = managedQuery(mCapturedImageURI, projection, null, null, null);
    int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst(); 
    capturedImage = cursor.getString(column_index_data);    
    String url = "http://xxxxxxxxxxxxxx.com/device_upload.php";
    new ProfileAddImageFileAsync().execute(url);
  }
}

And I am running a progress dialog box until the upload get completed, as follows

     class ProfileAddImageFileAsync extends AsyncTask<String, String, String> 
      {                     
            @Override
            protected void onPreExecute() 
            {
                super.onPreExecute();
                showDialog(DIALOG_DOWNLOAD_PROGRESS);
            }        
            protected String doInBackground(String... Aurl) 
            {

                    outputStream.writeBytes(lineEnd);
                    bytesAvailable = fileInputStream.available();
                    Log.e("bytesAvailable ",""+bytesAvailable);

    }

Please help me friends, the above code is my working code in my 5MP camera.

Answer 1

i got solution like this, i use to capture and compress the image.

Following is my camera part

 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
             file = new File(Environment.getExternalStorageDirectory(),  String.valueOf(System.currentTimeMillis()) + ".jpg"); 
             Log.e("ffffffffffiiiiiiiiilllllllllle ",""+file);
             f = String.valueOf(file);
             mCapturedImageURI = Uri.fromFile(file);
             Log.e("outputFileUri ",""+mCapturedImageURI);
             setupImage(intent);
             intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI); 
             startActivityForResult(intent, 3); 

i am uploading the image in OnActivity Result as follows

public void onActivityResult(int requestCode, int resultCode, final Intent data) 
{
  super.onActivityResult(requestCode, resultCode, data);
  if (requestCode == 3) 
  {     
      capturedImage = f;
      String url = "http://xxxxxxxxxxxxxx.com/device_upload.php";
      new ProfileAddImageFileAsync().execute(url);
  }
}

And i am running an progress dialog box until the upload get completed, as follows

 class ProfileAddImageFileAsync extends AsyncTask<String, String, String>
