Intent sharing         


        

Answer 1

Sharing with Facebook has the problem that it only accepts an url in the EXTRA_TEXT. The native FB app will then grab a text and an image from this url to compose the post. That's not a "bug" but the intended behaviour they give to the official app :-/

Take into account Twitter will only accept text/plain without any markup and with 144 chars at max.

I've made my own "Share" dialog to intercept all different behaviours and give to each target intent what they accepts: HTML, plain text, FB URL and Twitter short text.

Here comes the code:

public class ShareHelper implements AdapterView.OnItemClickListener {
            private static final String TAG = ShareHelper.class.getSimpleName();

            private Activity mContext;
            private Dialog mDialog;
            private LayoutInflater mInflater;
            private GridView mGrid;


   private ShareIntentAdapter mAdapter;
        private int mMaxColumns;

        private List plainTextActivities;
        private Set htmlActivitiesPackages;

        private String subject;
        private String textbody;
        private CharSequence htmlbody;
        private String twitterBody;
        private String facebookBody;

        public ShareHelper(Activity context, String subject, String textbody, CharSequence htmlbody, String twitterBody, String facebookBody) {
            this.mContext = context;

            this.subject = subject;
            this.textbody = textbody;
            this.htmlbody = htmlbody;
            this.twitterBody = twitterBody;
            this.facebookBody = facebookBody;
        }

        @SuppressLint("NewApi")
        public void share() {

            this.mInflater = LayoutInflater.from(mContext);

            final Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);

            sendIntent.setType(HTTP.PLAIN_TEXT_TYPE);
            plainTextActivities = mContext.getPackageManager().queryIntentActivities(sendIntent, 0);

            if (plainTextActivities.size() > 0) { 
                htmlActivitiesPackages = new HashSet();
                sendIntent.setType("text/html");
                final List htmlActivities = mContext.getPackageManager().queryIntentActivities(sendIntent, 0);
                for (ResolveInfo resolveInfo : htmlActivities) {
                    htmlActivitiesPackages.add(resolveInfo.activityInfo.packageName);
                }

                mAdapter = new ShareIntentAdapter();

                final View chooserView = mInflater.inflate(R.layout.dialog_share_us_chooser, null);
                mGrid = (GridView) chooserView.findViewById(R.id.resolver_grid);
                mGrid.setAdapter(mAdapter);
                mGrid.setOnItemClickListener(this);

                mMaxColumns = mContext.getResources().getInteger(R.integer.maxResolverActivityColumns);
                mGrid.setNumColumns(Math.min(plainTextActivities.size(), mMaxColumns));

                AlertDialog.Builder builder;
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                    builder = new AlertDialog.Builder(mContext, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
                } else {
                    builder = new AlertDialog.Builder(mContext);
                }
                builder.setTitle(R.string.text_share_us_title);
                builder.setView(chooserView);

                mDialog = builder.create();
                mDialog.show();
            } else {
                Toast.makeText(mContext, "No social apps installed to share ChurchLink!", Toast.LENGTH_LONG).show();
            }
        }

        @Override
        public void onItemClick(AdapterView parent, View view, int position, long id) {

            ResolveInfo info = (ResolveInfo) mAdapter.getItem(position);

            Intent intent = new Intent(android.content.Intent.ACTION_SEND);
            intent.setClassName(info.activityInfo.packageName, info.activityInfo.name);
            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TITLE, subject);
            intent.putExtra(Intent.EXTRA_SUBJECT, subject);

            if (info.activityInfo.packageName.contains("facebook")) {
                intent.putExtra(Intent.EXTRA_TEXT, facebookBody);

            } else if (info.activityInfo.packageName.contains("twitter")) {
                intent.putExtra(Intent.EXTRA_TEXT, twitterBody);

            } else if (htmlActivitiesPackages.contains(info.activityInfo.packageName)) {
                intent.putExtra(Intent.EXTRA_TEXT, htmlbody);

            } else {
                intent.putExtra(Intent.EXTRA_TEXT, textbody);
            }
            Log.d(TAG, info.activityInfo.packageName);
            ((Activity) mContext).startActivity(intent);

            mDialog.dismiss();
        }

        public class ShareIntentAdapter extends BaseAdapter {

            public ShareIntentAdapter() {
                super();
            }

            @Override
            public int getCount() {
                return plainTextActivities != null? plainTextActivities.size() : 0;
            }

            @Override
            public ResolveInfo getItem(int position) {
                return plainTextActivities.get(position);
            }

            @Override
            public long getItemId(int position) {
                return position;
            }

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View view;
                if (convertView == null) {
                    view = mInflater.inflate(R.layout.griditem_share_us, parent, false);
                } else {
                    view = convertView;
                }
                bindView(view, plainTextActivities.get(position));
                return view;
            }

            private final void bindView(View view, ResolveInfo info) {
                TextView text = (TextView)view.findViewById(android.R.id.text1);
                ImageView icon = (ImageView)view.findViewById(android.R.id.icon);

                text.setText(info.activityInfo.applicationInfo.loadLabel(mContext.getPackageManager()).toString());
                icon.setImageDrawable(info.activityInfo.applicationInfo.loadIcon(mContext.getPackageManager()));
            }
        }
    }

Seems like some people wants the layout files too. Here are they:

dialog_share_us_chooser.xml

griditem_share_us.xml (from own AOSP project):
