Android displaying image from Database

Android displaying image from Database - java

Hi I learned how to grab data from a SQL and display onto TextView. But I'm having little trouble displaying images.
The images are stored in the SQL database as URL but I can't display as an image onto the view.
I've done some research and found on "How to display image with given URL", but I'm just having a little difficulty understanding the concept of grabbing the URL and display .. Please kindly help me. Thank you!
This is the errorLog i'm getting.
Update
Line 159 : photoMe.setImageDrawable(drawable);

You don't seem to understand an AsyncTask. The point is that it does not run on the UI thread, making it possible to do long term IO like HTTP connections. Wrapping the entire doInBackground in a runOnUIThread is completely counter to that. Its not your only problem, but its on the list.
The rest is too hard to read due to formatting, but look on line 159. Some variable you're using there is null.

Writing a TableRow on UI thread with data from AsyncTask Thread

I have implemented a JSON Parser on a background thread and then am trying to write the data to a series of TableRows on the UI Thread using some embedded code which includes a handler to put me back on the normal UI Thread. The code continually comes back with this stack trace

I tried moving all the code into the AsyncTask but it then demands to be on the UI Thread.
Here is my code. Any help would be much appreciated.
protected Boolean doInBackground(final String... args) {
final TableLayout tl = (TableLayout) findViewById(R.id.table);
final TableRow v1 = new TableRow(MainActivity.this);
JSONParser jParser = new JSONParser();
String temp = "http://sandbox.kriswelsh.com/hygieneapi/hygiene.php?op=nearest&lat=" + latitude + "&long=" + longitude;
JSONArray json = jParser.getJSONFromUrl(temp);
int [] test = new int [10];
for (int i = 0; i < 10; i++) {
try {
JSONObject c = json.getJSONObject(i);
String vid = c.getString(id);
String vbn = c.getString(BusinessName);
String va1 = c.getString(Add1);
String va2 = c.getString(Add2);
String va3 = c.getString(Add3);
String vpost = c.getString(Post);
String vlong = c.getString(longitudej);
String vrate = c.getString(RatingDate);
String vratestar = c.getString(Rating);
String vlat = c.getString(latitudej);
if (vratestar.contentEquals("-1")) {
vratestar = "Exempt";
}
//testing(vbn,va1,va2,va3,vpost,vratestar);
//TableLayout tl = (TableLayout) findViewById(R.id.table);
isRunning = true;
new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
while (isRunning) {
try {
// Thread.sleep(10000);
mHandler.post(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
tl.addView(v1);
}
});
} catch (Exception e) {
// TODO: handle exception
}
}
}
}).start();
isRunning = false;
//jsonlist.add(map);
} catch (JSONException e) {
e.printStackTrace();
}
}
return null;
}
UPDATE: Now shows v1 initialization

Looking at your while (isRunning) loop I suppose you are trying to add the same v1 TableRow view to the TableLayout on each iteration (however, it is just a guess, because you didn't post v1 declaration). Of course, at the second time it will give you an error as it is already has parent, you should create new TableRow object each time. Going deeper, you don't need Handler which is connected to UI thread, because you are using AsyncTask, you can take advantage of the fact, that onPostExecute method is executed on the main thread. Considering it, you can write the following AsyncTask implementation:
class MyAsyncTask extends AsyncTask<Void, Void, JSONArray>{
#Override
protected JSONArray doInBackground(Void... params) {
JSONParser jParser = new JSONParser();
String temp = "http://sandbox.kriswelsh.com/hygieneapi/hygiene.php?op=nearest&lat=" + latitude + "&long=" + longitude;
JSONArray json = jParser.getJSONFromUrl(temp);
return json;
}
#Override
protected void onPostExecute(JSONArray json) {
TableLayout tl = (TableLayout) findViewById(R.id.table);
for (int i = 0; i < 10; i++) {
try {
JSONObject c = json.getJSONObject(i);
String vid = c.getString(id);
String vbn = c.getString(BusinessName);
String va1 = c.getString(Add1);
String va2 = c.getString(Add2);
String va3 = c.getString(Add3);
String vpost = c.getString(Post);
String vlong = c.getString(longitudej);
String vrate = c.getString(RatingDate);
String vratestar = c.getString(Rating);
String vlat = c.getString(latitudej);
if (vratestar.contentEquals("-1")) {
vratestar = "Exempt";
}
TableRow tableRow = new TableRow(context);
//configuring row, setting layout params
tl.addView(tableRow);
} catch (JSONException ex){
//error handling
}
}
}
}

URL cannot be cast to String

I am very new in android and trying to develop application to load all mp3 files from server to list-view and by clicking list item it should play that mp3 file directly from server.

The code:
myList.get(position)
is implicitly casting the element of myList to a String, since myList is a List<String>. This is failing because you managed to insert a URL object into myList.
Enable "unchecked cast" warnings, and you should see a warning where you are inserting into myList.
Two possible fixes:
Eliminate the unchecked cast. Part of that will probably involve calling .toString() on your URL before adding it to myList.
Or, change the type of myList to List<URL>, and then do the .toString() call inside onItemClick.
Which one you go with depends on the type you'd like myList to have.

I think that myList contains wrong objects. You put URIs inside it, not Strings. Use toString method on Uris when you filling list.
Find where you do this:
myList.add((String)uri);
and change to:
myList.add(uri.toString());

Invoke toString() method on the URL object to get the string form.
Refer http://docs.oracle.com/javase/6/docs/api/java/net/URL.html#toString%28%29

Your `Exception saying...
java.lang.ClassCastException: java.net.URL cannot be cast to java.lang.String
Which boldly indicating, you are trying to cast an URL to a String object...that means, baseURL is an URL object but you are trying to cast it to a String object, that's why Exception happening.
Now, Change the following...
String baseURL;
to
Uri baseURL;
As well as, where you are referencing baseURL as a String, change them as Uri.

Try removing all the unnecessary spaces in your URL by calling trim().
Please refer the below question as well
Android: howto parse URL String with spaces to URI object?

How to upload audio in soundcloud via my app and i want to send that id also to my server

How can i get the path and uplaod audio to soundcloud and then send id to my server side..

Replace this
UploadToSoundCloudTask uploadTask = new UploadToSoundCloudTask(this, wrapper); uploadTask.execute(new AudioClip(path));
By
UploadToSoundCloudTask uploadTask = new UploadToSoundCloudTask(ActivtiyName.this, wrapper); uploadTask.execute(new AudioClip(path));
In your case this does nto refer to activity context
To upload check the sample here
https://github.com/soundcloud/java-api-wrapper/blob/master/src/examples/java/com/soundcloud/api/examples/UploadFile.java
Downalod java-wrapper-api.jar and add it to libs folder
Get the path of the audio file from sdcard
To uplaod
http://developers.soundcloud.com/docs#uploading
Quoting from the above link
To upload a sound, send a POST request to the /tracks endpoint
Create a wrapper instance:
ApiWrapper wrapper = new ApiWrapper("client_id", "client_secret", null, null);
Obtain a token:
wrapper.login("username", "password");
Make a POST request to the /tracks endpoint. On Button click invoke AsyncTask
class TheTask extends AsyncTask<Void,Void,Void>
{
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try {
wrapper = new ApiWrapper("client_id",
"client_secret",
null,
null);
token = wrapper.login("username", "password");
upload();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
Upload method.
public void upload()
{
try {
Log.d("DDDDD", "uploading in background...");
File audioFile = new File("/mnt/sdcard/Music/A1.mp3");
// replace the hardcoded path with the path of your audio file
audioFile.setReadable(true, false);
HttpResponse resp = wrapper.post(Request.to(Endpoints.TRACKS)
.add(Params.Track.TITLE, "A1.mp3")
.add(Params.Track.TAG_LIST, "demo upload")
.withFile(Params.Track.ASSET_DATA, audioFile));
Log.i("......",""+Integer.valueOf(resp.getStatusLine().getStatusCode()));

ImageLoader NullPointerException for an off-screen, SlidingMenu item?

I'm parsing a JSON response from a weather feed and the data I receive includes a url to an icon that corresponds with the conditions, then I display that icon in an ImageView. I was able to make this work in a sandbox app before moving the package of code into my project.
In the main project I use the latest versions of ActionBarSherlock and SlidingMenu for navigation, and both apps make use of Android-Async-Http-Client but now it has a fatal NullPointerException when trying to display the icon from that url in the ImageView. I don't think this is caused by any of the libraries.
I've seen that sliding menus mostly consist of some type of ListView handled with an Adapter, which I'm doing in a portion of my sliding menu. But the only clue I have is that it crashes because now it's an off-screen UI element that I'm trying to work with. Does it matter that I have something in my sliding menu that isn't handled by an Adapter? I can't imagine much else is different but maybe you guys some clue of what I'm missing. Hopefully it isn't something basic that I'm just forgetting... or maybe it is :)
Alright, thanks for any ideas.

Yikes! I tried to post a "snippet" but maybe I should've posted the complete file...

Putting the updateWeatherUi() logic at inside the end of buildWeatherObject() fixed this for me.
The problem is that I'm still not sure what was occurring here previously. The Logs were showing the proper data right up to the point of imageLoader.DisplayImage(String, ImageView) in my original code but I kept crashing there with NullPointerException.
