IOException - Cannot load file

Question

I have an app that shows GIF images. It all works fine if image is saved in drawable, and I access it like this ``` is=context.getResources().openRawResource(R.drawable.mygif); movie = Movie.decodeStream(is); ``` But I need to download image from internet, so I'm saving it to CacheDir, that works fine. I tried the following to read it. ``` try { is = new BufferedInputStream(new FileInputStream(new File(context.getCacheDir(), "mygif.gif"))); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } movie = Movie.decodeStream(is); ``` And this ``` movie = Movie.decodeFile(new File(context.getCacheDir(), "mygif.gif").getPath()); ``` But no matter what, it ends with ``` java.io.IOException at java.io.InputStream.reset(InputStream.java:218) at android.graphics.Movie.decodeStream(Native Method) at android.graphics.Movie.decodeTempStream(Movie.java:74) at android.graphics.Movie.decodeFile(Movie.java:59) ``` or ``` java.io.IOException: Mark has been invalid…

Accepted Answer

suggestion:

1.try move the download location to another folder like: `sdcard`, or the app another folder except the `cache`.

2.when init the `inputstream`, try use: init with a buffer size

```
int buffersize = 16*1024;
InputStream  is = new BufferedInputStream(xxx,buffersize);
```

3.to check the file existed in your folder

update: change the code like this and dont use `Movie.decodeFile`

```
 InputStream is = null;
    try {
        is = new BufferedInputStream(new FileInputStream(new File(getCacheDir(), "mygif.gif")), 16 * 1024);
        is.mark(16 * 1024); 
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
movie = Movie.decodeStream(is);
```

no exception throw, and the `movie` is not null.

Also, although your code will throw the exception, the `movie` is also not null.
