Question

I’m trying to store some images, that I get as base64 coded strings, in the internal storage.
For some reason they don’t seem to be stored, and I have no clue why.

This is the function that stores them:

public void createImage(String image, String name){
    try{
        byte[] imageAsBytes = Base64.decode(image.getBytes(), Base64.DEFAULT);
        Bitmap img_bitmap = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);

        //mCtx is the context. It comes from the main activity
        FileOutputStream fos = mCtx.openFileOutput(name, Context.MODE_WORLD_READABLE);
        img_bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
        fos.flush();
        fos.close();

        //Let's check if they're there
        File f = new File(mCtx.getFilesDir().getPath() + "/" + name + ".png");

        if (f.exists())
             Log.v(DB_TAG, "Exists");
        else
             Log.v(DB_TAG, "Not exists");
    }
    catch(Exception e){
        e.printStackTrace();
        Log.e(DB_TAG, e.toString());
    }
}

I keep getting “Not exists” in the logcat. Why can that be?

Answer 1

File f = new File(mCtx.getFilesDir().getPath() + "/" + name); //<-- removed .png!
if (f.exists())
    Log.v(DB_TAG, "Exists");
else
    Log.v(DB_TAG, "Not exists");

You are saving your file as ‘name’ and then, the file you created as ‘name.png’.
