Teilen Bild via android-app mit ACTION_SEND nicht funktioniert

Habe ich Biene nach dieser

Android - Anteil auf Facebook, Twitter, E-Mail, ecc

Aber ich bin nicht in der Lage zu teilen, Bild mit action_send intent in android.Bitte siehe meinen code, und leite mich, wo ich falsch bin.

saveFileName = "";
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("image/*");
            Bitmap shareImage = null;
            shareImage = Bitmap.createBitmap(pc.getDrawingCache());
            OutputStream OS = null;
            File f1 = new File(Environment.getExternalStorageDirectory()
                    + "/Free Hand");
            if (f1.isDirectory() == false)
                new File(Environment.getExternalStorageDirectory()
                        + "/Free Hand").mkdir();
            SimpleDateFormat filename = new SimpleDateFormat("yyyyMMddHmmss");
            java.util.Date today1 = new java.util.Date();
            saveFileName = filename.format(new java.sql.Timestamp(today1
                    .getTime())) +  ".png";
            if (saveFileName.length() == 0)
                saveFileName = "Free Hand";
            file = new File(Environment.getExternalStorageDirectory()
                    + "/Free Hand", saveFileName);
            try {
                outStream = new FileOutputStream(file);
                shareImage.compress(Bitmap.CompressFormat.PNG, 100, outStream);

                share.putExtra(android.content.Intent.ACTION_SEND, Uri.parse(Environment.getExternalStorageDirectory()
                        + "/Free Hand/"+saveFileName+".png"));
                Toast.makeText(
                        getApplicationContext(),
                        "Saved in " + Environment.getExternalStorageDirectory()
                                + "/Free Hand" + "\nFile: " + saveFileName
                                + ".png", Toast.LENGTH_LONG).show();
                Log.v("Before image", "Before image");
                startActivity(Intent.createChooser(share, "Share Image"));
                Log.v("After image", "After image");
                outStream.flush();
                outStream.close();
                saveFileName = "";
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(),
                        "Exception : " + e.getMessage(), Toast.LENGTH_LONG)
                        .show();
            }
            save = false;

Die Logcat Ausgabe die ich bekomme, ist :

Ich bin es zu testen auf einem echten Gerät über USB-debugging.

Benutzen Sie einfach folgenden code-snippet :

try {
    File myFile = new File("/mnt/sdcard/images/2.png");
    MimeTypeMap mime = MimeTypeMap.getSingleton();
    String ext=myFile.getName().substring(myFile.getName().lastIndexOf(".")+1);
    String type = mime.getMimeTypeFromExtension(ext);
    Intent sharingIntent = new Intent("android.intent.action.SEND");
    sharingIntent.setType(type);
    sharingIntent.putExtra("android.intent.extra.STREAM",Uri.fromFile(myFile));   
    startActivity(Intent.createChooser(sharingIntent,"Share using"));
}
catch(Exception e){
    Toast.makeText(getBaseContext(), e.getMessage(),Toast.LENGTH_SHORT).show();  
}

nun es zeigt sich ein dialog sagen keine Anwendung, die diese Aufgabe ausführen können
Erstens sollten Sie eine Datei im Ordner mit dem Namen Bilder in Ihrem SDCard, jetzt Holen Sie sich das Bild an und den teilen....Es wird funktionieren
Dies funktionierte wirklich für mich.. danke
