  3.  
  4. InputStream is = this.getClass().getResourceAsStream(path) ;
Parsed in 0.012 seconds, using GeSHi 1.0.8.4


also try context.getResource().getraw Method ;
nothing works for me . all return null .

Hello Rizwan,

have you tried the following :?:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. FileInputStream android.app.ApplicationContext.openFileInput(String name) throws FileNotFoundException
Parsed in 0.011 seconds, using GeSHi 1.0.8.4


Where exactly is the file located you are trying to load :?:
  1. Desktop-PC-HDD
  2. Within the Android-Project
  3. On the Emulator-HDD

Hello Rizwan,

put the image you want to load to the following folder:
"/res/raw/myImage.png"

Then access it with the following code (I'm doing this to a mp3-File):
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. InputStream in = this.getResources().openRawResource(R.raw.everlast);
Parsed in 0.011 seconds, using GeSHi 1.0.8.4


With me in is not null, it is:
Code: Select all
in:   AssetManager$AssetInputStream  (id=830003249256)


This works ;) :!:
