AssetManager in android

Basically, Assets are a raw approach to resource management. We can place any files we want into the assets directory of our project.

If we have a reference to any Context subclass, such as an Activity, we can get a reference to the AssetManager instance provided by the platform:

  1. AssetManager assetManager = getAssets();

Once we have an AssetManager reference, we can just open a raw InputStream for any asset we put into the assets directory

Like in this way:

  1. <> InputStream input = null;
  3. <> try {
  5. <> input = assetManager.open("mytextfile.txt<> ");
  7. <> } catch (IOException e) {
  9. <> // handle
  11. <> }

Here is an example as a class having feature of text file reading via AssetManager

For instance

  1. public static class myData
  2. {
  3. public static void loadData(Context context)
  4. {
  6. try
  7. {
  8. AssetManager am = context.getAssets();
  9. InputStream is = am.open("mytextfile.txt");
  10. BufferedReader br =
  11. new BufferedReader(new InputStreamReader(is));
  12. String line = br.readLine();
  13. My_Name = line;
  14. line = br.readLine();
  15. My_Contact = Integer.parseInt(line);
  16. br.close();
  17. }
  18. catch (IOException e)
  19. {
  21. Log.e("Error", "Unable to read data from txt file");
  23. }
  24. }
  25. }
