Share image and text through Whatsapp or Facebook

I have in my app a share button and i want to share an image and a text at the same time. In GMail it works fine but in WhatsApp, only the image is sent and in Facebook the app crashes.
The code i use to share is this:
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Message");
Uri uri = Uri.parse("android.resource://" + getPackageName() + "/drawable/ford_focus_2014");
try {
InputStream stream = getContentResolver().openInputStream(uri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
If I use "shareIntent.setType("*/ *")" Facebook and WhatsApp crashes.
Is there some way to do this? Maybe sent two messages by separate at the same time (WhatsApp).
Thanks in advance.

Currently Whatsapp supports Image and Text sharing at the same time. (Nov 2014).
Here is an example of how to do this:
/**
* Show share dialog BOTH image and text
*/
Uri imageUri = Uri.parse(pictureFile.getAbsolutePath());
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
//Target whatsapp:
shareIntent.setPackage("com.whatsapp");
//Add text and then Image URI
shareIntent.putExtra(Intent.EXTRA_TEXT, picture_text);
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
shareIntent.setType("image/jpeg");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
ToastHelper.MakeShortText("Whatsapp have not been installed.");
}

Please try the below code and hopefully it will work.
Uri imgUri = Uri.parse(pictureFile.getAbsolutePath());
Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
whatsappIntent.setType("text/plain");
whatsappIntent.setPackage("com.whatsapp");
whatsappIntent.putExtra(Intent.EXTRA_TEXT, "The text you wanted to share");
whatsappIntent.putExtra(Intent.EXTRA_STREAM, imgUri);
whatsappIntent.setType("image/jpeg");
whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
activity.startActivity(whatsappIntent);
} catch (android.content.ActivityNotFoundException ex) {
ToastHelper.MakeShortText("Whatsapp have not been installed.");
}

For sharing text and image on WhatsApp, more controlled version of code is below, you can add more methods for sharing with Twitter, Facebook ...
public class IntentShareHelper {
public static void shareOnWhatsapp(AppCompatActivity appCompatActivity, String textBody, Uri fileUri) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.setPackage("com.whatsapp");
intent.putExtra(Intent.EXTRA_TEXT,!TextUtils.isEmpty(textBody) ? textBody : "");
if (fileUri != null) {
intent.putExtra(Intent.EXTRA_STREAM, fileUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("image/*");
}
try {
appCompatActivity.startActivity(intent);
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
showWarningDialog(appCompatActivity, appCompatActivity.getString(R.string.error_activity_not_found));
}
}
public static void shareOnTwitter(AppCompatActivity appCompatActivity, String textBody, Uri fileUri){...}
private static void showWarningDialog(Context context, String message) {
new AlertDialog.Builder(context)
.setMessage(message)
.setNegativeButton(context.getString(R.string.close), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setCancelable(true)
.create().show();
}
}
For getting Uri from File, use below class:
public class UtilityFile {
public static #Nullable Uri getUriFromFile(Context context, #Nullable File file) {
if (file == null)
return null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
try {
return FileProvider.getUriForFile(context, "com.my.package.fileprovider", file);
} catch (Exception e) {
e.printStackTrace();
return null;
}
} else {
return Uri.fromFile(file);
}
}
// Returns the URI path to the Bitmap displayed in specified ImageView
public static Uri getLocalBitmapUri(Context context, ImageView imageView) {
Drawable drawable = imageView.getDrawable();
Bitmap bmp = null;
if (drawable instanceof BitmapDrawable) {
bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
} else {
return null;
}
// Store image to default external storage directory
Uri bmpUri = null;
try {
// Use methods on Context to access package-specific directories on external storage.
// This way, you don't need to request external read/write permission.
File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
bmpUri = getUriFromFile(context, file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
}
For writing FileProvider, use this link: https://github.com/codepath/android_guides/wiki/Sharing-Content-with-Intents

As of now, a Whatsapp Intent supports image and text:
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT,title + "\n\nLink : " + link );
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(sharePath));
shareIntent.setType("image/*");
startActivity(Intent.createChooser(shareIntent, "Share image via:"));
The image will be as it is and EXTRA_TEXT will be shown as the caption.

try with this code
Uri imageUri = Uri.parse(Filepath);
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage("com.whatsapp");
shareIntent.putExtra(Intent.EXTRA_TEXT, "My sample image text");
shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
shareIntent.setType("image/jpeg");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
ToastHelper.MakeShortText("Kindly install whatsapp first");
}

public void shareIntentSpecificApps(String articleName, String articleContent, String imageURL) {
List<Intent> intentShareList = new ArrayList<Intent>();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
//shareIntent.setType("image/*");
List<ResolveInfo> resolveInfoList = getPackageManager().queryIntentActivities(shareIntent, 0);
for (ResolveInfo resInfo : resolveInfoList) {
String packageName = resInfo.activityInfo.packageName;
String name = resInfo.activityInfo.name;
Log.d("System Out", "Package Name : " + packageName);
Log.d("System Out", "Name : " + name);
if (packageName.contains("com.facebook") ||
packageName.contains("com.whatsapp")) {
Intent intent = new Intent();
intent.setComponent(new ComponentName(packageName, name));
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, articleName);
intent.putExtra(Intent.EXTRA_TEXT, articleName + "\n" + articleContent);
Drawable dr = ivArticleImage.getDrawable();
Bitmap bmp = ((GlideBitmapDrawable) dr.getCurrent()).getBitmap();
intent.putExtra(Intent.EXTRA_STREAM, getLocalBitmapUri(bmp));
intent.setType("image/*");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intentShareList.add(intent);
}
}
if (intentShareList.isEmpty()) {
Toast.makeText(ArticleDetailsActivity.this, "No apps to share !", Toast.LENGTH_SHORT).show();
} else {
Intent chooserIntent = Intent.createChooser(intentShareList.remove(0), "Share Articles");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentShareList.toArray(new Parcelable[]{}));
startActivity(chooserIntent);
}
}
You can share image also I have done in my app like mentioned in above code.

My second answer for this question is: I'm pasting full code here because new developer need sometimes full code.
public class ImageSharer extends AppCompatActivity {
private ImageView imgView;
private Button shareBtn;
FirebaseStorage fs;
StorageReference sr,sr1;
String Img_name;
File dir1;
Uri uri1;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.app_sharer);
imgView = (ImageView) findViewById(R.id.imgView);
shareBtn = (Button) findViewById(R.id.shareBtn);
// Initilize firebasestorage instance
fs=FirebaseStorage.getInstance();
sr=fs.getReference();
Img_name="10.jpg";
sr1=sr.child("shiva/"+Img_name);
final String Paths= Environment.getExternalStorageDirectory()+ File.separator+"The_Bhakti"+File.separator+"Data";
dir1=new File(Paths);
if(!dir1.isDirectory())
{
dir1.mkdirs();
}
sr1.getFile(new File(dir1,Img_name)).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
sr1.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
uri1= Uri.parse(uri.toString());
}
});
}
}) ;
shareBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
uri1=Uri.parse(Paths+File.separator+Img_name);
Intent intent=new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
//intent.putExtra(intent.EXTRA_SUBJECT,"Insert Something new");
String data = "Hello";
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(Intent.EXTRA_TEXT,data);
intent.putExtra(Intent.EXTRA_STREAM,uri1);
intent.setPackage("com.whatsapp");
// for particular choose we will set getPackage()
/*startActivity(intent.createChooser(intent,"Share Via"));*/// this code use for universal sharing
startActivity(intent);
// end Share code
}
});
}// onCreate closer
}

Use this code for sharing on whatsapp or on another package with image and video. Here the URI is the path of image. If image in Memory then it took fast loading and if you are using url then sometimes images don't load and links gone direct.
shareBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
uri1=Uri.parse(Paths+File.separator+Img_name);
Intent intent=new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
//intent.putExtra(intent.EXTRA_SUBJECT,"Insert Something new");
String data = "Hello";
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(Intent.EXTRA_TEXT,data);
intent.putExtra(Intent.EXTRA_STREAM,uri1);
intent.setPackage("com.whatsapp");
startActivity(intent);
// end Share code
}
If this code is not understandable then see the full code in my other answer.

Actually. it is possible to send image and text through WhatsApp by downloading the image to device external storage and then share the image to WhatsApp.
if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
Bitmap bm = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
Intent intent = new Intent(Intent.ACTION_SEND);
String share_text = "image and text";
intent.putExtra(Intent.EXTRA_TEXT, notification_share);
String path = MediaStore.Images.Media.insertImage(MainActivity.this.getContentResolver(), bm, "", null);
Uri screenshotUri = Uri.parse(path);
intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));
} else {
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
}
//The above code works perfect need to show image in an imageView

This works:
<activity android:name="com.selcuksoydan.sorucevap.Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.SEND" />
<data android:mimeType="image/*" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
soru_image = (ImageView) soruView.findViewById(R.id.soru_image);
soru_image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
v.buildDrawingCache();
Bitmap bitmap = v.getDrawingCache();
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/SoruCevap");
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception ex) {
//ignore
}
Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
waIntent.setType("image/*");
waIntent.setPackage("com.whatsapp");
waIntent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.fromFile(file));
getContext().startActivity(Intent.createChooser(waIntent, "Share with"));
} catch (Exception e) {
Log.e("Error on sharing", e + " ");
Toast.makeText(getContext(), "App not Installed", Toast.LENGTH_SHORT).show();
}

This worked for me in January 2019
private void shareIntent() {
Bitmap imgBitmap = BitmapFactory.decodeResource(getResources(),R.drawable.ic_launcher);
String imgBitmapPath = MediaStore.Images.Media.insertImage(getContentResolver(),imgBitmap,"title",null);
Uri imgBitmapUri = Uri.parse(imgBitmapPath);
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM,imgBitmapUri);
shareIntent.setType("image/png");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.putExtra(Intent.EXTRA_TEXT, "My Custom Text ");
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject text");
startActivity(Intent.createChooser(shareIntent, "Share this"));
}
This will let the user share the image + text to WhatsApp and all other apps the user wants, it's always the best to let the user select where to share the content instead of prompting just WhatsApp.
Also make sure that if you include just WhatsApp to share it might not be installed in some devices, for this you will need a try catch and inside of it the startActivity(intent); and also set the package of the intent to just WhatsApp with intent.setPackage("com.whatsapp").

Copy text from anywhere.let it be Google, Facebook or whatsapo itself
attempt to upload the image in whatsapp anywhere.at contact or group.before you hit the send image arrow... you will see caption option to that image... touch and hold, a paste option will appear.hit paste... your text will show up... then you can send the photo.and it will appear with the text you wanted... there you go... you have the text and image in it... the only problem will be the text size, which is limited to certain number of words
😀 This works for Android users only

add image to twitter share intent android

I'm trying to add an image to my twitter share intent. I save an image locally in one class and then in another I get the image and try to attach to my intent.
Here is my code
private void shareTwitter(){
try {
FileInputStream fis;
fis = getActivity().openFileInput("photo.jpg");
Bitmap shot = BitmapFactory.decodeStream(fis);
File file = new File(MapView.path, "snapshot.jpg");
if(file.exists()){
Log.i("FILE", "YES");
}else{
Log.i("FILE", "NO");
}
Uri uri = Uri.parse(file.getAbsolutePath());
//Uri uri = Uri.parse("android.resource://com.gobaby.app/drawable/back");
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("/*");
intent.setClassName("com.twitter.android", "com.twitter.android.PostActivity");
intent.putExtra(Intent.EXTRA_TEXT, "Thiws is a share message");
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(intent);
} catch (final ActivityNotFoundException e) {
Toast.makeText(getActivity(), "You don't seem to have twitter installed on this device", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
At the moment there is no exception in my logcat my app just displays a toast saying image failed to load.
Please what an I doing wrong?

This is what you need
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file);

This might be helpful for somebody:
private void sendShareTwit() {
try {
Intent tweetIntent = new Intent(Intent.ACTION_SEND);
String filename = "twitter_image.jpg";
File imageFile = new File(Environment.getExternalStorageDirectory(), filename);
tweetIntent.putExtra(Intent.EXTRA_TEXT, getString(R.string.twitter_share_text));
tweetIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
tweetIntent.setType("image/jpeg");
PackageManager pm = getActivity().getPackageManager();
List<ResolveInfo> lract = pm.queryIntentActivities(tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);
boolean resolved = false;
for (ResolveInfo ri : lract) {
if (ri.activityInfo.name.contains("twitter")) {
tweetIntent.setClassName(ri.activityInfo.packageName,
ri.activityInfo.name);
resolved = true;
break;
}
}
startActivity(resolved ?
tweetIntent :
Intent.createChooser(tweetIntent, "Choose one"));
} catch (final ActivityNotFoundException e) {
Toast.makeText(getActivity(), "You don't seem to have twitter installed on this device", Toast.LENGTH_SHORT).show();
}
}

Here is solution:
private fun shareOnTwitter() {
val file = File(context!!.filesDir, FILENAME_SHARE_ON_TWITTER)
val uriForFile = FileProvider.getUriForFile(context!!, com.yourpackage.activity.YourActivity, file)
val intent = Intent(Intent.ACTION_SEND).apply {
type = "image/jpeg"
putExtra(Intent.EXTRA_STREAM, uriForFile)
}
startActivity(intent)
}

How can I post on Twitter with Intent Action_send?

I have been struggling to send text from my app to Twitter.
The code below works to bring up a list of apps such as Bluetooth, Gmail, Facebook and Twitter, but when I select Twitter it doesn't prefill the text as I would have expected.
I know that there are issues around doing this with Facebook, but I must be doing something wrong for it to not be working with Twitter.
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Example Text");
startActivity(Intent.createChooser(intent, "Share Text"));

I'm using this snippet on my code:
private void shareTwitter(String message) {
Intent tweetIntent = new Intent(Intent.ACTION_SEND);
tweetIntent.putExtra(Intent.EXTRA_TEXT, "This is a Test.");
tweetIntent.setType("text/plain");
PackageManager packManager = getPackageManager();
List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(tweetIntent, PackageManager.MATCH_DEFAULT_ONLY);
boolean resolved = false;
for (ResolveInfo resolveInfo : resolvedInfoList) {
if (resolveInfo.activityInfo.packageName.startsWith("com.twitter.android")) {
tweetIntent.setClassName(
resolveInfo.activityInfo.packageName,
resolveInfo.activityInfo.name);
resolved = true;
break;
}
}
if (resolved) {
startActivity(tweetIntent);
} else {
Intent i = new Intent();
i.putExtra(Intent.EXTRA_TEXT, message);
i.setAction(Intent.ACTION_VIEW);
i.setData(Uri.parse("https://twitter.com/intent/tweet?text=" + urlEncode(message)));
startActivity(i);
Toast.makeText(this, "Twitter app isn't found", Toast.LENGTH_LONG).show();
}
}
private String urlEncode(String s) {
try {
return URLEncoder.encode(s, "UTF-8");
} catch (UnsupportedEncodingException e) {
Log.wtf(TAG, "UTF-8 should always be supported", e);
return "";
}
}
Hope it helps.

you can simply open the URL with the text and Twitter App will do it. ;)
String url = "http://www.twitter.com/intent/tweet?url=YOURURL&text=YOURTEXT";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
and it will also open the browser to login at the tweet if twitter app is not found.

Try this, I used it and worked great
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/intent/tweet?text=...."));
startActivity(browserIntent);

First you have to check if the twitter app installed on the device or not then share the text on twitter:
try
{
// Check if the Twitter app is installed on the phone.
getActivity().getPackageManager().getPackageInfo("com.twitter.android", 0);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setClassName("com.twitter.android", "com.twitter.android.composer.ComposerActivity");
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "Your text");
startActivity(intent);
}
catch (Exception e)
{
Toast.makeText(getActivity(),"Twitter is not installed on this device",Toast.LENGTH_LONG).show();
}

For sharing text and image on Twitter, more controlled version of code is below, you can add more methods for sharing with WhatsApp, Facebook ... This is for official App and does not open browser if app not exists.
public class IntentShareHelper {
public static void shareOnTwitter(AppCompatActivity appCompatActivity, String textBody, Uri fileUri) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.setPackage("com.twitter.android");
intent.putExtra(Intent.EXTRA_TEXT,!TextUtils.isEmpty(textBody) ? textBody : "");
if (fileUri != null) {
intent.putExtra(Intent.EXTRA_STREAM, fileUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("image/*");
}
try {
appCompatActivity.startActivity(intent);
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
showWarningDialog(appCompatActivity, appCompatActivity.getString(R.string.error_activity_not_found));
}
}
public static void shareOnWhatsapp(AppCompatActivity appCompatActivity, String textBody, Uri fileUri){...}
private static void showWarningDialog(Context context, String message) {
new AlertDialog.Builder(context)
.setMessage(message)
.setNegativeButton(context.getString(R.string.close), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setCancelable(true)
.create().show();
}
}
For getting Uri from File, use below class:
public class UtilityFile {
public static #Nullable Uri getUriFromFile(Context context, #Nullable File file) {
if (file == null)
return null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
try {
return FileProvider.getUriForFile(context, "com.my.package.fileprovider", file);
} catch (Exception e) {
e.printStackTrace();
return null;
}
} else {
return Uri.fromFile(file);
}
}
// Returns the URI path to the Bitmap displayed in specified ImageView
public static Uri getLocalBitmapUri(Context context, ImageView imageView) {
Drawable drawable = imageView.getDrawable();
Bitmap bmp = null;
if (drawable instanceof BitmapDrawable) {
bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
} else {
return null;
}
// Store image to default external storage directory
Uri bmpUri = null;
try {
// Use methods on Context to access package-specific directories on external storage.
// This way, you don't need to request external read/write permission.
File file = new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "share_image_" + System.currentTimeMillis() + ".png");
FileOutputStream out = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
bmpUri = getUriFromFile(context, file);
} catch (IOException e) {
e.printStackTrace();
}
return bmpUri;
}
}

How to open Facebook and Twitter in android

Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/html");
String str = et.getText().toString();
i.putExtra(android.content.Intent.EXTRA_TEXT,str);
startActivity(Intent.createChooser(i,"Share using"));
I can't open Facebook and Twitter with this code in Android but other applications like Gmail and Skype are opened successfully. Why's that? And how do I open Facebook and Twitter?

Can you try this code:
private void facebooktaPaylas() {
try {
String facebookUri = "http://m.facebook.com/sharer.php?u=";
String marketUri = "your sharing text");
Intent shareOnFacebookIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse(facebookUri + marketUri));
startActivity(shareOnFacebookIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
private void twitterdaPaylas() {
try {
String facebookUri = "http://mobile.twitter.com/home?status=";
String marketUri = "your sharing text";
Intent shareOnFacebookIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse(facebookUri + marketUri));
startActivity(shareOnFacebookIntent);
} catch (Exception e) {
e.printStackTrace();
}
}

How about changing the MIME type to "text/*"?
It seems that Facebook and Twitter can deal with "text/plain" instead of "text/html".

Open Twitter app from other app and load some page

Is there a way to open the Twitter app from my own application?
For example, I have my own Android app and I want to open Twitter app using Intent.
How can I do that?
Answers with example would be much appreciated.

try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name=" + twitter_user_name)));
}catch (Exception e) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/#!/" + twitter_user_name)));
}
This should do the necessary work for you.

Expanding on #Chrishan's answer you can open the twitter app to perform different functions based on the uri (list below from this post)
twitter://user?screen_name=lorenb
twitter://user?id=12345
twitter://status?id=12345
twitter://timeline
twitter://mentions
twitter://messages
twitter://list?screen_name=lorenb&slug=abcd
twitter://post?message=hello world
twitter://post?message=hello world&in_reply_to_status_id=12345
twitter://search?query=%23hashtag
e.g.
String uriStr = "twitter://post?message=hello world"
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(uriStr)));
}catch (Exception e) {
//the user doesn't have twitter installed
}
NOTE: I have only tried user and post, so if you come across any that don't work please let me know and I will update this answer.

If the user already has Twitter installed on their phone, something like this should take care of it:
try{
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "this is a tweet");
intent.setType("text/plain");
final PackageManager pm = getPackageManager();
final List<?> activityList = pm.queryIntentActivities(intent, 0);
int len = activityList.size();
for (int i = 0; i < len; i++) {
final ResolveInfo app = (ResolveInfo) activityList.get(i);
if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) {
final ActivityInfo activity=app.activityInfo;
final ComponentName name=new ComponentName(activity.applicationInfo.packageName, activity.name);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
intent.setComponent(name);
startActivity(intent);
break;
}
}
}
catch(final ActivityNotFoundException e) {
Log.i("twitter", "no twitter native",e );
}

I use this:
Intent i = getOpenTwitterIntent(this, "UserName");
startActivity(i);
And the function:
public static Intent getOpenTwitterIntent(Context c, String Username) {
try {
c.getPackageManager().getPackageInfo("com.twitter.android", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name="+ Username));
} catch (Exception e) {
return new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/#!/" + Username));
}
}
If Twitter app is intalled in the device, this open that, else open web browser...

private void showTwitter(){
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.twitter.android", "com.twitter.android.ProfileActivity");
this.startActivity(intent);
}
