<p>I have used this example here.
<a href="http://stackoverflow.com/questions/6979521/move-raw-file-to-sd-card-in-android">Move Raw file to SD card in Android</a></p>
<p>The issue is
1. The app seems to read the .m4a file I want (possible reads the bytes wrong here).
2. When the file is saved to the /tmp dir the file size is totally wrong.
eg one file goes from 30kb to 300kb, another goes from 25kb, to .25kb. </p>
<p>Any suggestions</p>
<pre><code>public String saveAs(int ressound, String whipName){
byte[] buffer=null;
InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
int size=0;
try {
size = fIn.available();
buffer = new byte[size];
fIn.read(buffer);
fIn.close();
} catch (IOException e) {
// TODO Auto-generated catch block
Log.i("saveas", "did not save1");
//return false;
}
String path= Environment.getExternalStorageDirectory().getAbsolutePath()+"/tmp/.pw2";

4,989,321 | 4,989,322 | Compare dictionary values and key in python | <p>I have a dictionary <code>item</code>. It has strings as keys and the values are lists e.g.:</p>
<pre><code>item['title'] = [u'python']
item['image'] = [u'/link/to/image']
item['link'] = [u'link to article']
</code></pre>
<p>I want to check if any value is 0 in length, but link or image may be empty, so I did the following:</p>
<pre><code> for key, value in item.iteritems():
if len(value) == 0:
if key != 'image' or key != 'link':
raise DropItem("Item is empty: %s" %item)

<p>Now when I want to read the value of "name" and "photoUri" fields, it gives me "Object is not an instance of class". Following is the code:</p>
<pre><code>void printValues() {
try {
Class cls = Class.forName("my.pkg.name.TestClass$MyStaticClass");
for(Field field: cls.getDeclaredFields()) {
System.out.println("Field name: " + field.getName());
System.out.println("Field value: " + field.get(cls));
}
} catch (Throwable e) {
e.printStackTrace();

</code></pre>
<p>I also tried to pass "null" at field.get(null) to read the value but it gives null pointer exception.</p>
<p>Please help me, how can I read the value of the field "name" and "photoUri"?</p>

<p>I used a cursorLoader() to access the the Contacts and displayed it in a listView.

<p>My question is do I have to use ContentResolver().insert() for this or is there a way to do it using CursorLoader() itself. Is CursorLoader() just for accessing data ? </p>

I know it is because I am using "this" in my script, but I can't get it working without this. If my code is not the way to do this, I am open to other suggestions. Here is my code, which is wrapped in document.ready higher up in the script:</p>
<pre><code>$("button#add-friend").click(function (e) {
$(this).trigger('addFriend');
});
$('#add-friend').on('addFriend', function() {
$(this).append('<input type="text" value="Friend"><span id="add"><input type="button" id="add-friend" value="+"></span><br/>');
