Sorry had to laugh but I feel for you!

Could you post your current code for what path you are selecting?

And could you clarify if you main problem is selecting the external storage path that will have sufficient space?

For android there are 2 positions

a) internal

b) external (still on device on some devices)

c) external (sdcard on some devices)

Option C is device specific.

either way, the readily availablle path can be found with

http://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory%28%29

This is the function I use to find the best cache directory (for pictures, just change the subdir to whatever is most appropriate).

public static File getBestExtDir(Context applicationContext) {
    File path;

    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        path = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "Pictures");
    }
    else {
        //lets try internal storage
        path = applicationContext.getCacheDir();
    }

    if (path.exists()) {
        return path;
    }
    if (path.mkdirs()) {
        return path;
    }

    return null;
}

OK, now it will Solved but again I have a problem When i clear a catch then all the download content will be remove from their — Alpan, Apr 29 '13 at 07:22

yes you are right you can not prevent this ....if you clear it all data will be loss ..its depend on you where you want to save the data....internally or externally ..in externally you can prevent the data loss on clear – Monty Apr 29 '13 at 07:21
And how we can Store data externally same as a data/data/applicationcontext/myfile/myfile2 – Alpan Apr 29 '13 at 07:33
i think you did not gone through my given link .....you need to give your external sdcard given path. – Monty Apr 29 '13 at 08:43

Use Environment.getExternalStorageDirectory to find path to SD card.
