Android Error - Open Failed ENOENT

Question

I am trying to save some block coverage using an array of integers that simply saves the number of times a block is executed  For some reason  though  when I try and write to some files that I created   BlockForHelper txt  for example  which I made specifically in Eclipse and placed in the project directory   I get this error   java io FileNotFoundException    nfs guille groce users nicholsk workspace3 SQLTest BlockForTest  open failed  ENOENT  No such file or directory  at libcore io IoBridge open IoBridge java 416  at java io FileOutputStream  lt init gt  FileOutputStream java 88  at java io FileOutputStream  lt init gt  FileOutputStream java 73  at com example sql2 SQLTest blockCoverage SQLTest java 149  at com example sql2 test SQLTestCase testSuite SQLTestCase java 41  at java lang reflect Method invokeNative Native Method  at android test InstrumentationTestCase runMethod InstrumentationTestCase java 214  at android test InstrumentationTestCase runTest InstrumentationTestCase java 199  at android test ActivityInstrumentationTestCase2 runTest ActivityInstrumentationTestCase2 java 192  at android test AndroidTestRunner runTest AndroidTestRunner java 190  at android test AndroidTestRunner runTest AndroidTestRunner java 175  at android test InstrumentationTestRunner onStart InstrumentationTestRunner java 555  at android app Instrumentation InstrumentationThread run Instrumentation java 1584  Caused by  libcore io ErrnoException  open failed  ENOENT  No such file or directory  at libcore io Posix open Native Method  at libcore io BlockGuardOs open BlockGuardOs java 110  at libcore io IoBridge open IoBridge java 400      18 more   and gives me the error   public void blockCoverage   throws IOException       String coverage           for  int x   0  x  lt  20  x            coverage    x         bb count x      n        File file   new File   nfs guille groce users nicholsk workspace3 SQLTest BlockForTest txt        Writer out   new OutputStreamWriter new FileOutputStream file       Here     try               out write coverage         finally           out close              Anyone know what might be causing this

With sdk  you can t write to the root of internal storage  This cause your error   Edit    Based on your code  to use internal storage with sdk   final File dir   new File context getFilesDir       nfs guille groce users nicholsk workspace3 SQLTest    dir mkdirs      create folders where write files final File file   new File dir   BlockForTest txt

Put the text file in the assets directory  If there isnt an assets dir create one in the root of the project  Then you can use Context getAssets   open  BlockForTest txt    to open a stream to this file
