Image Slider using Pager-view with Bitmap not working

Dear All I use PagerView to make a slider images and every thing went well
if I use a URL images and String array from drawable images.
But when I use a file stored in my APP directory its not work you will see my code here
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

}
}
I user some tools to download files and store it in imgPath
Images is downloaded and stored and no issue for it
but the issue that
bitmap.size();
always empty and the APP Crashed

The problem is in my DownloadTask not in the code itself.
I solve it by changing the download task to code:

new Thread(new Runnable() {
public void run() {
try {
System.out.println(url+saveName);
URL sourceUrl = new URL(url+saveName);
URLConnection conn = sourceUrl.openConnection();
conn.connect();
InputStream inputStream = conn.getInputStream();
int fileSize = conn.getContentLength();
File savefilepath = new File(savePath);
if (!savefilepath.exists()) {
savefilepath.mkdirs();
}
File savefile = new File(savePath+saveName);
if (savefile.exists()) {
savefile.delete();
}
savefile.createNewFile();
FileOutputStream outputStream = new FileOutputStream(savePath+saveName, true);
byte[] buffer = new byte[1024];
int readCount = 0;
int readNum = 0;
int prevPercent = 0;
while (readCount < fileSize && readNum != -1) {
readNum = inputStream.read(buffer);
if (readNum > -1) {
outputStream.write(buffer, 0, readNum);
readCount = readCount + readNum;
int percent = (int) (readCount * 100 / fileSize);
if (percent > prevPercent) {
System.out.println(percent);
//Toast.makeText(LoadPage.MY_CONTEXT,percent,Toast.LENGTH_LONG);
prevPercent = percent;
}
}
}
outputStream.flush();
outputStream.close();
inputStream.close();
//Thread.sleep(50);
} catch (Exception e) {
System.out.println( e);
}
}
}).start();
}

Storing seriaized ArrayList in SharedPreferences - ArrayList is empty when retrieving

The below code is certainly not the best way of doing what I need to do but unfortunately I don't have much time to go back and change data structures / storage options etc. It will be cleaned up however. Anyway, the quality of the code isn't my problem, I digress.
When the user registers their account for the first time, they are given a ListView with multiple choice (check boxes). The selected items are stored in a SparseBooleanArray then converted to an ArrayList of Strings.
The names of the ListView items are coming from an SQLite database method called getStoreNames() which returns an ArrayList of Strings of the Store names.
I need to then get the Store objects associated with each store name. This is done in the for loop within the continue_button case. (Store store = db.returnStoreByName(storeName)... then adding each of those stores to an ArrayList of Stores.
I am then trying to store this ArrayList of stores in SharedPreferences. Because SPs doesn't support ArrayLists, the data is serialized. In the next Activity when I try to access the Store objects, I deserialize the shared preference object. However when I checked the size of the deserialized ArrayList, it is 0. I checked the arraylist size before I serialized it and put it into shared preferences and it was giving the correct size.
This leads me to believe that somewhere between serializing/deserializing or storing in/retrieving from shared prefs is where something is going wrong and the arraylist is being emptied.
Here is the first activity where the data is saved to shared prefs.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mad.losesano2/com.mad.losesano2.LoggedInActivity}: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
From this Logcat it's clear that your array size is 0 and you are trying to access index 0. Make sure you check array length before accessing its content.
May be you are getting crash for this line
Log.d("LoSeSANO", "Store name at index 0: " + store_list.get(0).getName());
check store_list size before accessing it's index.

I saw u only store a simple List then you didnt easy way to share data.
Okey with small data like this : SparseBooleanArray a = list_view.getCheckedItemPositions();
I will create class
Class A implement Serializable{
List<String> data;
}
then send Serializable via Intent.

Android Augmented Reality Pro AR 9: activity gets back when displays too many markers

I'm using this very useful tutorial (https://github.com/RaghavSood/ProAndroidAugmentedReality) for developing a custom AR app.
It works pretty fine, but when I display markers extracted from a file folder (sometimes) the app gets blocked and restarts from the previous activity.
I suppose it's because of the big number of markers situated in the same point of the screen.
Infact, when I lower the radius, and then showing a littler number of markers, the activity continues to work.
Besides, I've tried to modify the function "getTextWidth()" as many people suggest on the net.
I don't know how to reduce the number of Markers drawn on the same point of the screen (so indipendently from reducing the radius). Can you suggest me something? THANKS A LOT!!!!!
I show you the LocalDataSource.java modified:

I would like to thank the Author of the Tutorial who helped me in fixing the problem.
I report his answer that soled my problem:
Not sure why you have that limitation but this should limit the number of Markers drawn on the screen.
In class AugmentedView.java
You can introduce a new member variable:
private static int MAX_NUM_TO_DRAW = 10;
Then in the method onDraw(Canvas canvas):
You can quit the drawing loop early.
int i=0;
ListIterator<Marker> iter = collection.listIterator(collection.size());
while (iter.hasPrevious() && i<MAX_NUM_TO_DRAW ) {
Marker marker = iter.previous();
marker.draw(canvas);
i++;
}

Android-World Clock Widget analog

Can I use my own custom view in the widget, apart from analog clock? Or is there any other way to show the clock? like use the Imageview as the clock face and to draw the dial according to the time?
Please help me regarding this.!!!:(

A similar example for thermometer is given in this link
http://mindtherobot.com/blog/272/android-custom-ui-making-a-vintage-thermometer/
You can create your own view and make the clock as well.

You can replaced the clock dial, clock hand minute and clock hand hour with your own drawings. Then You'll have your own custom clock.
android:dial="#drawable/YOUR_OWN_DIAL"
android:hand_hour="#drawable/YOUR_OWN_HOUR"
android:hand_minute="#drawable/YOUR_OWN_MINUTE"
Test the layout in the Graphical Layout Tool to see how it look like.

Android application loading issue

I am developing an application on Android 2.2 . Mainly what it does , is that it grab data from the internet and then it shows it on the device's screen. I have finished an Activity , but , it is too slow , it takes too much to get the web content . I would like to make it run faster .

The Activity takes too much time to load .(About 10 seconds) . So please , can you help me figure out where and how to insert the Async Task ? Or maybe you can suggest me something else to make the application run faster ? Something like a handler for example ? I don't really know much since I am new to Android programming . Any advice would be much appreciated . Thanks.

1) You need improve your code style
2) For such purposes you must use AsynchTask or Handler+Separate Thread
