Question

I am trying to save image to SD card and I added some code for it.But after clicking the “OK”/Checkmark in the camera, my app exits.Would I have to check if the directory that I am trying to store it in exists?How would i do that?.. !file.exists(){file.mkdirs}? ..In my code I have tried to store it in /Android folder which exists in every SD card.

           file = new File(Environment.getExternalStorageDirectory().getPath()
                 + "/Android/" + "bhe_app" + ".jpg");

    imageUri = Uri.fromFile(file);

i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

        startActivityForResult(i, cameraData);

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        bmp = (Bitmap) extras.get("data");
        iv.setImageBitmap(bmp);


    }
}

Create the directory before creating the File.

boolean createdDirectory = new File(Environment.getExternalStorageDirectory().getPath() + "/directory1/directory2/directory3/").mkdirs();

the variable createdDirectory will be

true if and only if the directory was created, along with all
necessary parent directories; false otherwise

You will have to make sure that your app has the permission to write to the SD Card(Check your AndroidManifest.xml)

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
