I followed the Kii Cloud tutorial on creating and archieving an object, and tried to implement it to my own app. What it basically does is, when user clicks on the "existingButton", it opens a new activity where user can pick an image from the gallery and upload it. I'm facing no issues on the second activity, yet the uri from the first activity comes as "null" to the second activity and I'm getting a NullPointerException eventually, since I'm trying to parse a null String. I examined this issue through debugger and found out that the problem is in the first activity's "onSaveCompleted" method. The if (exception == null) condition is not met, which basically means that I'm getting some kind of an exception, I guess. Then, if (exception instanceof CloudExecutionException) condition is not met, too. As a result, it shows the Toast of the else condition of my main if. Code is below. Thanks for any help guys.
First Activity:
public class SendNotePreActivity extends AppCompatActivity {
public static final String APP_BUCKET_NAME = "tutorial";
#Override

setContentView(R.layout.activity_send_note_pre);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Button existingButton = (Button) findViewById(R.id.existingButton);
existingButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
KiiBucket bucket = Kii.bucket(APP_BUCKET_NAME);
KiiObject object = bucket.object();
object.set("deneme", 313131);
object.save(new KiiObjectCallBack() {
#Override
public void onSaveCompleted(int token, #NonNull KiiObject object,
Exception exception) {

Move startActivity into onSaveCompleted, because now you start the 2nd activity before save is finishec

As mentioned in the comment, you can get the absolute path from the saved image and pass it through an intent to the Activity that it needs it.
To achieve this, you might want to convert your image file to a BitMap first, which will give you the actual path of the image (sometimes .getAbsolutePath() method returns a wrong file path, so it is a better solution to convert your image to a bitmap first).
This can be achieved:
String filePath = file.getPath();
Bitmap imgBitmap = BitmapFactory.decodeFile(filePath);
Then to obtain the real path of the image you saved you need to
1) Obtain the Uri of the created Bitmap:
public Uri getUri(Context context, Bitmap imgBitmap) {
ByteArrayOutputStream bOutputStream = new ByteArrayOutputStream();
String path = MediaStore.Images.Media.insertImage(context.getContentResolver(),
imgBitmap, "Title", null);
return Uri.parse(path);
}
2) Fetch the real path from Uri:
public String getRealPath(Uri uri) {
String [] proj={MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
In your first activity you can pass the path of your image through an intent to the other activity, then fetch it and display it/etc.
Intent intent = new Intent(context,OtherActivity.class);
intent.putExtra("PATH",path);
startActivity(intent);
Receive the data you passed:
Intent intent = getIntent();
String path = intent.getStringExtra("PATH");
//convert the path to image/bitmap and display the image
You can also pass the entire Bitmap to the Activity you need it, but I strongly recommend that you don't, because it will use a lot of memory.

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.
Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.
I am selecting an image from gallery in onActivityResult method and I can get image path in this method. Now I want to upload this image in servlet and this uploading task, I want to do in AsyncTask doInBackground method, but I can not access image path from onActivityResult to doInBackGround method.
I don't know how to achieve this. I am putting my code here:
public class Photos extends ActionBarActivity {
private static final int REQUEST_ID = 1;
private static final int HALF = 6;
Button mUpload;
ImageView mPhoto;
Button mDoUpload;
Intent data;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_photos);
mPhoto = (ImageView) findViewById(R.id.uploaded_photo);
mUpload = (Button) findViewById(R.id.btn_photoshare);
mDoUpload = (Button) findViewById(R.id.btn_upload);
mUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, REQUEST_ID);
}
});
mDoUpload.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
InputStream stream = null;
if(requestCode == REQUEST_ID && resultCode == Activity.RESULT_OK)
{
try
{
stream = getContentResolver().openInputStream(data.getData());
//System.out.println(data.getData());
Bitmap original = BitmapFactory.decodeStream(stream);
((ImageView)findViewById(R.id.uploaded_photo)).setImageBitmap(Bitmap.createScaledBitmap(original, original.getWidth()/HALF,
original.getHeight()/HALF, true));
String path = getRealPathFromURI(getApplicationContext(), data.getData());
System.out.println(path);
}
catch(Exception ex)
{
ex.printStackTrace();
}
if(stream != null)
{
try
{
stream.close();
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}
}
public String getRealPathFromURI(Context context,Uri contentUri)
{
Cursor cursor = null;
try
{
String[] proj = {MediaStore.Images.Media.DATA};
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
// System.out.println(cursor.getString(column_index));
return cursor.getString(column_index);
}
finally {
if (cursor != null) {
cursor.close();
}
}
}
private class sendFile extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... params)
{
HttpURLConnection httpConn=null;
try
{
File uploadFile = new File(path);
//here I dont know how to access selected image path
}
catch(Exception ex)
{
ex.printStackTrace();
}
return null;
}
}
That's because you made path a local variable of onActivityResult(). Make it a variable of your activity. Change String path = getRealPathFromURI(.. to path = getRealPathFromURI(... And declare String path=""; in the activity.
I am a web dev and a couple of weeks ago I started trying to learn android studio and app dev. Im currently using kii cloud for my android app and I am currently trying to figure out how implement the following scenario --
a. I already have user registration, so I am currently working on a "edit profile" page.
b. On the edit profile page Im trying to create a button so that the user clicks on it and it will then open a fragment where the user can upload the image. link
c. Then attach that image to the url, and use the URL where needed such as a view profile page. linkenter link description here
EditUserProfile.java
public class EditUserProfile extends Activity {
Button picbutton;
#Override

if(fragment == null)
fragment = new ProfilePic();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.fragcon, fragment);
ft.commit();

Then for things like this, Im trying to find a way to dynamically show the profile pictures associated with the users, and if not use the icon as default.
holder.icon.setImageResource(R.drawable.list_account);
UserListLoader.java
public class UserListAdapter extends AbstractArrayAdapter<IUser> {
private final LayoutInflater inflater;
public UserListAdapter(Context context) {
super(context, R.layout.image_list_item);
this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = this.inflater.inflate(R.layout.image_list_item, parent, false);
holder = new ViewHolder();
holder.text = (TextView)convertView.findViewById(R.id.row_text);
holder.icon = (ImageView)convertView.findViewById(R.id.row_icon);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
IUser user = this.getItem(position);
holder.position = position;
holder.text.setText(user.getUsername());
holder.icon.setImageResource(R.drawable.list_account);
return convertView;
}
}
Also when opening in app, the EditUserProfile crashes at
picbutton.setOnClickListener(new View.OnClickListener()
Any guidance or help on the matter is appreciated. Thanks.
I hope this helped someone...
