Sharing images and text with Facebook on Android

Why? Because they are Facebook and can permit to themselves such bugs.So, they expect only images upon type is "image/". If the type is "text/plain"-then a URL should be contained in the message. Don't use .setType("/*");Otherwise use their SDK. But in this case you'll sacrifice simplicity and flexibility of your application.

Solution to the following highlighted problems.

Please attach only photos or a single video.

Facebook isn't in the Share option Dialog

even if Facebook wall appears, then it won't let you open your image on the front page.

Share an image on Facebook without using Facebook SDK

I got lucky after searching for three days constantly. Sorry, The answer might be lengthy, because I found no solution on StackOverflow that could share an image on Facebook without using Facebook SDK.

Here is the full and perfect solution:

Bitmap bitmap = viewToBitmap(load your image OR layout background for your imageView);shareImage(bitmap, "com.facebook.katana");

The first parameter is the imageView/layout for the images that are loaded into the bitmap. The second parameter is the facebook's package name.

Then code the following Method as shown.

public void shareImage(Bitmap bitmap, String packageName) {        try {            File file = new File(this.getExternalCacheDir(), "temp.png");            FileOutputStream fileOutputStream = new FileOutputStream(file);            bitmap.compress(Bitmap.CompressFormat.PNG, 95, fileOutputStream);            fileOutputStream.flush();            fileOutputStream.close();            file.setReadable(true, false);            final Intent intent = new Intent(android.content.Intent.ACTION_SEND);            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));            intent.setType("image/*");            intent.setPackage(packageName);            startActivity(Intent.createChooser(intent, "Share image on facebook"));        } catch (Exception e) {            Log.e(TAG, e.toString());            Toast.makeText(this, "Error while sharing Image on Facebook", Toast.LENGTH_SHORT).show();        }    }

Here're my app Screenshots:

1. "Quote book App" is loading a picture with a quote on it.

2. Click the share button and click on Facebook from the dialog.

3. Facebook sharing options dialog appears.

4. Image loaded to the Facebook front page.

5. Finally the Image is shared on Facebook And the method is working properly as we expected.

PS: You can check out this functionality in my app, Here's the Link to download it from google play store.

There is only one solution you can create the bitmap of text and image using canvas and share it on facebook. (Download source code here)

Here is my code:
