[Q] Really confused and annoyed right now - Android Q&A, Help & Troubleshooting

Can somebody please tell me how these bits of code
Code:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri originalUri = data.getData();
selectedImageImageView.setImageURI(originalUri);
selectedImageImageView.setVisibility(View.VISIBLE);
progressDialog.setProgress(0);
progressDialog.show();
new GetImageFileTask(this).execute(imageHelper,
selectedImageImageView);
}
super.onActivityResult(requestCode, resultCode, data);
}
Code:
public static final int GALLERY_KITKAT_INTENT_CALLED = 2;
public static final int GALLERY_INTENT_CALLED = 1;
private final int PREF_WIDTH_IMAGE = 500;
private Activity activity;
public ImageHelper(Activity activity) {
this.activity = activity;
}
public void getImage() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
activity.startActivityForResult(intent, GALLERY_INTENT_CALLED);
} else {
showKitKatGallery();
}
}
private void showKitKatGallery() {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
activity.startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
}
public File getFileFromImageView(ImageView imageView) throws IOException {
int preferredWidth = PREF_WIDTH_IMAGE;
Bitmap origBitmap = drawableToBitmap(imageView.getDrawable());
int origWidth = origBitmap.getWidth();
int origHeight = origBitmap.getHeight();
int destHeight, destWidth;
if (origWidth <= preferredWidth || origHeight <= preferredWidth) {
destWidth = origWidth;
destHeight = origHeight;
} else {
destWidth = PREF_WIDTH_IMAGE;
destHeight = origHeight / (origWidth / destWidth);
}
File tempFile = new File(activity.getCacheDir(), "temp.png");
tempFile.createNewFile();
Bitmap bitmap = resizeBitmap(origBitmap, destWidth, destHeight);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 0, bos);
byte[] bitmapData = bos.toByteArray();
FileOutputStream fos = new FileOutputStream(tempFile);
fos.write(bitmapData);
fos.close();
return tempFile;
}
public static Bitmap drawableToBitmap(Drawable drawable) {
if (drawable == null) {
return null;
}
if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable) drawable).getBitmap();
}
int width = drawable.getIntrinsicWidth();
width = width > 0 ? width : 1;
int height = drawable.getIntrinsicHeight();
height = height > 0 ? height : 1;
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
private Bitmap resizeBitmap(Bitmap inputBitmap, int newWidth, int newHeight) {
return Bitmap.createScaledBitmap(inputBitmap, newWidth, newHeight, true);
}
}
have managed to come up with this error:

Because i don't know if any of you have seen my thread about my new app "Blox Backup" but the launch has been a big massive flop due this problem.
Now what i don't get is that it was all working as it should before i signed then published it?! I mean i know that apps don't work on every phone but this simply will not work at all no matter the phone!
So can someone please review the code and see where the null pointer is coming from because it shouldn't be coming up as null especially when it didn't before. I have tried to get an answer on Stack but nobody has bothered
So yeah please give me hand because i need this app back on Gplay
Thanks

I'm on my phone right now and have just taken a quick look, but my understanding is that "selectedImageView" is null. You could use something like Eclipse's debugging tool to check in real time where the crash happens and due to what.

So I've been playing around with it and it doesn't crash any more but it'll just finish the intent then do nothing. so nothing is being uploaded...
Code:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == imageHelper.GALLERY_KITKAT_INTENT_CALLED) {
Uri originalUri = data.getData();
selectedImageImageView.setImageURI(originalUri);
selectedImageImageView.setVisibility(View.VISIBLE);
progressDialog.setProgress(0);
progressDialog.show();
new GetImageFileTask(this).execute(imageHelper,
selectedImageImageView);
}else{
if(resultCode == imageHelper.GALLERY_INTENT_CALLED){
Uri originalUri = data.getData();
selectedImageImageView.setImageURI(originalUri);
selectedImageImageView.setVisibility(View.VISIBLE);
progressDialog.setProgress(0);
progressDialog.show();
new GetImageFileTask(this).execute(imageHelper,
selectedImageImageView);
}
}
super.onActivityResult(requestCode, resultCode, data);
}
Code:
public int GALLERY_KITKAT_INTENT_CALLED = 2;
public int GALLERY_INTENT_CALLED = 1;
public ImageHelper(Activity activity) {
this.activity = activity;
}
public void getImage() {
if (Build.VERSION.SDK_INT < 19) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
activity.startActivityForResult(intent, 2);
} else {
showKitKatGallery();
}
}
private void showKitKatGallery() {
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
activity.startActivityForResult(intent, 1);
}
I also have a feeling this
Code:
public class GetImageFileTask extends AsyncTask<Object, Object, Object> {
private OnGetImageFileListener listener;
public GetImageFileTask(OnGetImageFileListener listener) {
this.listener = listener;
}
@Override
protected Object doInBackground(Object[] params) {
File imageFile = null;
ImageHelper imageHelper = (ImageHelper) params[0];
ImageView imageView = (ImageView) params[1];
try {
imageFile = imageHelper.getFileFromImageView(imageView);
} catch (IOException e) {
e.printStackTrace();
}
return imageFile;
}
@Override
protected void onPostExecute(Object imageFile) {
listener.onGotImageFile((File) imageFile);
}
}
may have something to do with the problem but i could be wrong

Click to expand...
Click to collapse
I done but it didn't show anything that i didn't already know

Right i give up, I've tried every single "solution" but absolutely nothing works, so i have no idea what's happened but it won't work so this app, unless someone can actually fix it, is going to off the play store

Okay, I'm feeling very very stupid right now, it turns out i forgot i deleted the imageview from the layout but made a rookie mistake and left the code. I'm such a twat.
