How can i send a Bitmap[] to service class?

Question

I want to send the bitmap of the images to the service class and i want to use that bitmap there to set wallpaper The code i used is....

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if (requestCode == PICK_IMAGE_MULTIPLE) {
                imagesPathList = new ArrayList<String>();
                String[] imagesPath = data.getStringExtra("data").split("\\|");
                try {
                    lnrImages.removeAllViews();
                } catch (Throwable e) {
                    e.printStackTrace();
                }
                for (int i = 0; i < imagesPath.length; i++) {
                    imagesPathList.add(imagesPath[i]);
                    yourbitmap = BitmapFactory.decodeFile(imagesPath[i]);
                    resized[i] = Bitmap.createScaledBitmap(yourbitmap, 480,
                            800, true);
                    ImageView imageView = new ImageView(this);
                    imageView.setImageBitmap(resized[i]);
                    imageView.setAdjustViewBounds(true);
                    lnrImages.addView(imageView);
                }
            }
        }

    }



case R.id.btnsetwall:
            Intent i = new Intent(MainActivity.this, WallService.class);
            Log.i("Main Activity", "Before putExtra");
            i.putExtra("Imagess", resized);
            Log.i("Main Activity", "After putExtra");
            startService(i);
            Log.i("Main Activity", "Start Service");
            break;

//If i use i.putExtra("Imagess", resized); it gives error and if i dont use this line service gets started

In service class...

@Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();
        Log.i("on create", "Service Created");

    }

The logcat is...

05-06 15:53:57.932: I/Main Activity(14185): Before putExtra
05-06 15:53:57.932: I/Main Activity(14185): After putExtra

public class MainActivity extends Activity implements View.OnClickListener { private Bitmap resized[] = new Bitmap[10]; — nawaab saab, May 06 '14 at 10:41
resized[] = new Bitmap[imagesPath.length]; for (int i = 0; i < imagesPath.length; i++) try this — duggu, May 06 '14 at 10:43
need to use Parceable to send Array of bitmap...have a look [here](http://stackoverflow.com/a/15102154/2591002) — SweetWisher ツ, May 06 '14 at 11:12

Bitmap class itself implemented parcelable interface. So you can pass array of bitmaps just by calling Bitmap[] btmaps = new Bitmap[10]; Intent intent = new Intent(); intent.putExtra("bitmaps", btmaps);

And you can receive this array through intent as

Bitmap[] btmpList = (Bitmap[]) intent.getParcelableArrayExtra("bitmaps");

If you want to use a bitmap in different areas of your app you do not pass them around. You are on a very limited memory machine keep a bitmap as little time as possible in the heap.

The way you do it, you just save it to a file temporarly and then load it whereever you need it again.

Get your cache dir

public static String getCacheDir(Context ctx) {
        return Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()) ||!Environment.isExternalStorageRemovable() ?
                ctx.getExternalCacheDir().getPath() : ctx.getCacheDir().getPath();
    }

Save the bitmap

public static File saveBitmap(Bitmap bitmap, String filename, String path, boolean recycle) {
        FileOutputStream out=null;
        try {
            File f = new File(path,filename);
            if(!f.exists()) {
                f.createNewFile();
            }
            out = new FileOutputStream(f);
            if(bitmap.compress(Bitmap.CompressFormat.PNG, 90, out)) {
                return f;
            }
        } catch (Exception e) {
            Log.e(TAG, "Could not save bitmap", e);
        } finally {
            try{
                out.close();
            } catch(Throwable ignore) {}
            if(recycle) {
                bitmap.recycle();
            }
        }
        return null;
    }

Then load it again.

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
selected_photo.setImageBitmap(bitmap);

You could also look into Picasso which handles async loading for you and also enhances Performance with a disk cache and many more features

Picasso.with(getContext()).load(bitmapFile).into(imageView);

you can solve this in different different way with your requirement.

u can use static variable for storing imageBitmap

u can pass with intent

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);    
byte[] byteArray = stream.toByteArray();    
Intent in1 = new Intent(this, Activity2.class);    
in1.putExtra("image",byteArray);

i didnot get, this went above my head – nawaab saab May 06 '14 at 11:01
convert bitmap to byte[] and pass with intent – SuN May 06 '14 at 11:07
or u can directly convert stream to byteArry on onActivityResult and send with intent.putExtra() – SuN May 06 '14 at 11:08
one more solution is make bitmap varible to public static and use in service – SuN May 06 '14 at 11:08
-1 these are all bad solutions. Bitmap in a static is a memory leak bound to happen und putting heavy weigth into an intentdis a) very slow and b) also intents have upper size limits (1MB with GB as I remembter) – Patrick May 06 '14 at 11:16
@for3st so how may i do this? – nawaab saab May 06 '14 at 11:27

store bitmap file in sd card and get in service with your own name – SuN May 06 '14 at 12:33
