File not found exception Android java

Question

I am developing an android app and I want to read an xsl file. I have following code

    File rootPath=Environment.getExternalStorageDirectory();
   try {
    File randomContactsFile = new File(rootPath.getPath()+"/assets/LoginTest.xlsx");
    System.out.println(randomContactsFile.exists());
    }catch(Exception e){
    }

randomContactsFile.exists() returns false and I'm getting file not found exception.

Please help.

Thanks

Did you check if the file is present on the sd card in assets folder?? — Rachita Nanda, Aug 01 '13 at 10:13
*randomContactsFile.exists() return false and getting file not found exception.* That's obvious isn't it ! — AllTooSir, Aug 01 '13 at 10:13

May This Help you:

You will not be able to access assets/ at runtime using File.
You access assets/ at runtime using AssetManager, which you can get via getResources().getAssets().

Like:

AssetManager assetManager = getResources().getAssets();

And use assetManager.open(your file name);

Edit:

InputStream is = //Open file, and get inputstream
Workbook workBook = WorkbookFactory.create(is);
int totalSheets = workBook.getNumberOfSheets();
for (int i = 0; i <= totalSheets - 1; i++) {
  Sheet sheet = workBook.getSheetAt(i);
  // Do something with the sheet
}

Thanks, but my eclipse not recognizing getAssets() method. do we need to use context? Actually i want to open a xls file with FileInputStream – itin Aug 01 '13 at 11:01
@itin: yes buddy it uses context.. if your class extends Activity then it will not require otherwise you will need it... – Bhavin Nattar Aug 01 '13 at 11:03
but actually i can not extends the Activity class as i have already extends the ActivityInstrumentationTestCase2. I want to read xls file using poi which need FileInputStream. – itin Aug 01 '13 at 15:28
my code is fis = new FileInputStream(path); workbook = new XSSFWorkbook(fis); so context.getResources().getAssets().open not work i think... please advice... – itin Aug 01 '13 at 15:32

Solved:

if you get this exception even when you are sure that you have included all the jars then create a libs folder in the project root directory and copy all jars in libs folder. the add these jars in java build path (select all jars and right click add jars.)
