ORIGINAL: In my application, I call my own camera from the code, my intention is to take a picture from the camera and get its path to the file and also show it in the image view.
below is the code from AlertDialog.Builder
//run camera builder.setNegativeButton("Resim Cek", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { //native camera // here,counter will be incremented each time,and the picture taken by camera will be stored as 1.jpg,2.jpg and likewise. count++; String file = dir+count+".jpg"; File newfile = new File(file); try { newfile.createNewFile(); } catch (IOException e) {} Uri outputFileUri = Uri.fromFile(newfile); Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); startActivityForResult(cameraIntent, TAKE_PHOTO_CODE); dialog.dismiss(); } });
in onActivityResult
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) { Log.d("CameraDemo", "Pic saved"); final File file = getTempFile(this); try { Media.getBitmap(getContentResolver(), Uri.fromFile(file) ); String image_string = Uri.fromFile(file).toString(); Bitmap bm = Bitmap.createScaledBitmap( BitmapFactory.decodeFile(image_string), getResources().getDisplayMetrics().widthPixels, getResources().getDisplayMetrics().heightPixels, true); bmpPhoto = bm; bmpPhotoPath =image_string; imageView.setImageBitmap(bmpPhoto); removePhoto.setVisibility(View.VISIBLE); } catch (FileNotFoundException e) { Toast.makeText(getApplicationContext(), "file not found exception", Toast.LENGTH_SHORT).show(); } catch (IOException e) { Toast.makeText(getApplicationContext(), "ioexception", Toast.LENGTH_SHORT).show(); } }
and it always happens for a FileNotFoundException, how can I solve this?
since i use try catch it doesn't give much log
05-26 10:04:12.620: D/CameraDemo(3794): Pic saved
after changing onActivityResult
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) { Log.d("CameraDemo", "Pic saved"); //final File file = getTempFile(this); File outputDir = ContactFormActivity.this.getCacheDir(); // context being the Activity pointer File file = null; try { file = File.createTempFile("prefix", "extension", outputDir); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { Media.getBitmap(getContentResolver(), Uri.fromFile(file) ); String image_string = Uri.fromFile(file).toString(); Bitmap bm = Bitmap.createScaledBitmap( BitmapFactory.decodeFile(image_string), getResources().getDisplayMetrics().widthPixels, getResources().getDisplayMetrics().heightPixels, true); bmpPhoto = bm; bmpPhotoPath =image_string; imageView.setImageBitmap(bmpPhoto); removePhoto.setVisibility(View.VISIBLE); } catch (FileNotFoundException e) { Toast.makeText(getApplicationContext(), "file not found exception", Toast.LENGTH_SHORT).show(); } catch (IOException e) { Toast.makeText(getApplicationContext(), "ioexception", Toast.LENGTH_SHORT).show(); } }
