ADT Updates Problem

When Updating ADT in Eclipse, I get the problem.

At last I found that it is due to admin right program in Windows 7.  I need to run Eclipse as administrator in order to successfully upgated ADT in Eclipse.

Check Time for the program

 long count = System.currentTimeMillis();
   :
   : // Your code to measure time
   :
count = System.currentTimeMillis() - count;
Log.d("Graph draw","Time (ms): " + count);

Android Assets

Android offers one more directory where you can keep files to be included in the package: /assets. It’s at the same level as /res, meaning it’s not part of the /res subdirectories. The files in /assets do not generate IDs in R.java; you must specify the file path to read them. The file path is a relative path starting at /assets.

String getStringFromAssetFile(Activity activity) {
 AssetManager am = activity.getAssets();
 InputStream is = am.open("test.txt");
 String s = convertStreamToString(is);
 is.close();
 return s;
}

Android Resources - RAW

Android also allows raw files in addition to arbitrary XML files. These raw resources, placed in /res/raw, are raw file resources such as audio, video, or text files that require localization or references through resource IDs.

String getStringFromRawFile(Activity activity)
throws IOException {
 Resources r = activity.getResources();
 InputStream is = r.openRawResource(R.raw.test);
 String myText = convertStreamToString(is);
 is.close();
 return myText;
}
String convertStreamToString(InputStream is)
throws IOException {
 ByteArrayOutputStream baos = new ByteArrayOutputStream();
 int i = is.read();
 while (i != -1) {
  baos.write(i);
  i = is.read();
 }
 return baos.toString()
}

Android Resources - Arbitrary XML

Android allows arbitrary XML files as resources.

XML files that need to be read in this fashion are stored under the /res/xml subdirectory.

<rootelem1>
<subelem1>
Hello World from an xml sub element
</subelem1>
</rootelem1>

Resources res = activity.getResources();
XmlResourceParser xpp = res.getXml(R.xml.test);

private String getEventsFromAnXMLFile(Activity activity)
throws XmlPullParserException, IOException {
 StringBuffer sb = new StringBuffer();
 Resources res = activity.getResources();
 XmlResourceParser xpp = res.getXml(R.xml.test);
 xpp.next();
 int eventType = xpp.getEventType();
 while (eventType != XmlPullParser.END_DOCUMENT) {
  if(eventType == XmlPullParser.START_DOCUMENT) {
   sb.append("******Start document");
  }
  else if(eventType == XmlPullParser.START_TAG) {
   sb.append("\nStart tag "+xpp.getName());
  }
  else if(eventType == XmlPullParser.END_TAG) {
   sb.append("\nEnd tag "+xpp.getName());
  }
  else if(eventType == XmlPullParser.TEXT) {
   sb.append("\nText "+xpp.getText());
  }
  eventType = xpp.next();
 }//eof-while
 sb.append("\n******End document");
 return sb.toString();
}//eof-function
