Android, How to store image in internal storage?

android, bitmap

Solution

outputImage.toString() is not the image :) the contant you put on the file is not the binary data, but some string!

A way to do it is this:

public String writeFileToInternalStorage(Context context, Bitmap outputImage) {
    String fileName = Long.toString(System.currentTimeMillis()) + ".png";

    final FileOutputStream fos = openFileOutput(fileName, Context.MODE_PRIVATE);
    outputImage.compress(CompressFormat.PNG, 90, fos);
}

I coded directly into the browser, it is possible to have some syntax errors, but the code should work.

Problem

I want to store bitmap image on internal storage (not external storage). I have written this code but it seems something has problem. Because when i download image from DDMS, I can't open it. ``` public String writeFileToInternalStorage(Context context, Bitmap outputImage) { String fileName = Long.toString(System.currentTimeMillis()) + ".png"; try { OutputStreamWriter osw = new OutputStreamWriter(context.openFileOutput(fileName, Context.MODE_PRIVATE)); osw.write(outputImage.toString()); Log.i(TAG, "Image stored at: " + fileName); } catch (Exception e) { Log.w(TAG, e.toString()); fileName = null; } return fileName; } ```
