Body
copied!<p>I need a help with this Android application! I'm at very beginning in developing on Android and for a school's project I have to create an App that scan qr's codes and shoot photo.</p> <p>I have a problem on shooting photo, I'd like to shoot the photo, confirm it pressing "tick button", open a new intent that allow you to add a comment on Image, and then through another button I'll ad inside an ArrayAdapter.</p> <p>I'll try to show you the parts of the code that have problem, if anything more is needed just ask!</p> <p>The method TakePhoto is inside a Fragment that launch the camera intent pressing a button.</p> <p>public void TakePhoto() {</p> <pre><code> Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); int imageNum = 0; File imagesFolder = new File(Environment.getExternalStorageDirectory(),"aMuse"); imagesFolder.mkdirs(); String fileName = "image_" + String.valueOf(imageNum) + ".jpg"; File output = new File(imagesFolder, fileName); while (output.exists()){ imageNum++; fileName = "image_" + String.valueOf(imageNum) + ".jpg"; output = new File(imagesFolder, fileName); } Uri uriSavedImage = Uri.fromFile(output); intent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage); getActivity().startActivityForResult(intent, 100); } </code></pre> <p>The onActivityResult is inside a FragmentActivity that contains 2 more Fragment, and I'll need to pass the image shooted to another intent (imageResult) that will show the photo shooted and permit to add comment through an EditText.</p> <p>public void onActivityResult(int requestCode, int resultCode, Intent intent) {</p> <pre><code> super.onActivityResult(requestCode, resultCode, intent); IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent); if (scanResult != null) { Intent qrResult = new Intent(this, QrResult.class); String resultString = scanResult.getContents(); qrResult.putExtra(EXTRA_MESSAGE, resultString); startActivity(qrResult); } else{ switch (requestCode) { case 100: if (resultCode == Activity.RESULT_OK) { Intent imageResult = new Intent(this, ImagePreview.class); startActivity(imageResult); } } </code></pre> <p>}</p> <p>In this situation the app (as I understood) save the photo inside SD/aMuse with name image_nn.jpg. What I need to do is get this photo and set inside imageResult as bitmap. I tried passing the uri through .putExtra method but it crash giving "null pointer exception" error.</p>
