  1. POAndroid Launching Camera Intent from Fragment
    text
    copied!<p>I currently have an activity that hosts multiple fragments and I am on my third fragment of a collection.</p> <p>In that fragment I use an Intent to launch either the Camera or Gallery. See code:</p> <pre><code>public Intent getImageIntent() { // Camera. final List&lt;Intent&gt; cameraIntents = new ArrayList&lt;Intent&gt;(); final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); final PackageManager packageManager = context.getPackageManager(); final List&lt;ResolveInfo&gt; listCam = packageManager.queryIntentActivities(captureIntent, 0); for (ResolveInfo res : listCam) { final String packageName = res.activityInfo.packageName; final Intent intent = new Intent(captureIntent); intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name)); intent.setPackage(packageName); cameraIntents.add(intent); } // Filesystem. final Intent galleryIntent = new Intent(); galleryIntent.setType("image/*"); galleryIntent.setAction(Intent.ACTION_GET_CONTENT); // Chooser of filesystem options. final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source"); // Add the camera options. chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[] {})); // Calling activity should exeecute: // startActivityForResult(chooserIntent, 1); return chooserIntent; } </code></pre> <p>After that the onActivityResult executes:</p> <pre><code>private void handleSmallCameraPhoto(Intent intent) { Bundle extras = intent.getExtras(); mProductBitmap = (Bitmap) extras.get("data"); imgProduct.setImageBitmap(mProductBitmap); } </code></pre> <p>Where mProductBitmap is a Bitmap Global Variable and imgProduct is an ImageView already initialized.</p> <p><strong>For some reason, first: The Camera option force closes the app, and gets a null pointer from the actual fragment itself, like the fragment items are all null again. Second: The gallery options (More then one) don't error out but don't show the image either.</strong></p> <p>Any help would be appreciated. I've looked at every response possible, but not many people call an intent from a fragment that isn't the initial fragment that the activity is hosting. Thanks!</p> <p>EDIT: Found out sometimes my Context is Null after the onActivityResult. If anyone has encountered this help is appreciated. Thanks.</p> <p>EDIT: Below is by onActivityResult method, most of the time the first if should be executed.</p> <pre><code>@Override public void onActivityResult(int requestCode, int resultCode, Intent intent) { if (resultCode == Activity.RESULT_OK) { handleSmallCameraPhoto(intent); } else { if (requestCode == 1) { InputStream stream = null; if (intent == null) { System.out.println("DATA IS NULL.."); } else { try { if (mProductBitmap != null) { mProductBitmap.recycle(); } stream = getActivity().getContentResolver().openInputStream( intent.getData()); mProductBitmap = BitmapFactory.decodeStream(stream); System.out.println(mProductBitmap); System.out.println("Setting image result"); imgProduct.setImageBitmap(mProductBitmap); } catch (FileNotFoundException e) { e.printStackTrace(); } finally { if (stream != null) try { stream.close(); } catch (IOException e2) { e2.printStackTrace(); } } } } } } </code></pre>
