How to covert String[] to Bitmap[]?

Question

I am making a project in which wallpaper will be changed after every 10 seconds I am able to set Bitmap array to the Service class using this code

resized[i]=    Bitmap.createScaledBitmap(yourbitmap, 480,800, true);
Intent i = new Intent(MainActivity.this,WallService.class);
                    i.putExtra("Imagess", resized);
                    startService(i);

In the service class i am using this code:

 String[] Bits = intent.getStringArrayExtra("Imagess");
        for(int i =0; i<Bits.length;i++){

        getApplicationContext().setWallpaper(Bits[i]);
        Thread.sleep(10000);
        }

It is giving error in this line The method setWallpaper(Bitmap) in the type Context is not applicable for the arguments (String). So what must I do so that i can set wallpapers by conerting String[] to Bitmap[]

Update 1:

Bitmap[] Bits = (Bitmap[]) intent.getExtras().getParcelableArray("Imagess");
        for(int i =0; i<Bits.length;i++){


        try {
            getApplicationContext().setWallpaper(Bits[i]);
            Thread.sleep(10000);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        }

How do you get "Bits" array? Like this: Bitmap[] Bits = (Bitmap[]) getIntent().getExtras().getParcelableArray("Imagess"); ? — krossovochkin, May 06 '14 at 06:53

You are wrong using this code line:

 String[] Bits = intent.getStringArrayExtra("Imagess");

You put Parcelable[] to intent extras, but trying to get String[]. Use:

Bitmap[] Bits = (Bitmap[]) getIntent().getExtras().getParcelableArray("Imagess");

Update: If you init Bits array in Service onStart(Intent intent, int startId) method, then update this line:

Bitmap[] Bits = (Bitmap[]) getIntent().getExtras().getParcelableArray("Imagess");

to:

Bitmap[] Bits = (Bitmap[]) intent.getExtras().getParcelableArray("Imagess");

As you see, I replaced getIntent() method by intent argument from onStart(Intent intent, int startId) method
