How to Share both image and text through whatsapp android programatically

I need to share both an image and some text via WhatsApp, using an Intent on Android.
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, Uri.parse(imageUrl));
shareIntent.setType("image/png");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(shareIntent);
} catch (android.content.ActivityNotFoundException ex) {
ToastHelper.MakeShortText("Kindly install whatsapp first");
}
I’m using the code above, but it throws a 'File format not supported' error while sharing.

You can try like this
public static void shareOnWhatsapp(Context context, String str) {
Uri parse = Uri.parse(str);
Intent intent = new Intent();
intent.setAction("android.intent.action.SEND");
intent.setPackage("com.whatsapp");
String stringBuilder = context.getResources().getString(R.string.play_more_app) +
context.getPackageName();
intent.putExtra("android.intent.extra.TEXT", stringBuilder);
intent.putExtra("android.intent.extra.STREAM", parse);
intent.setType("image/*");
intent.addFlags(1);
try {
context.startActivity(intent);
} catch (Exception unused) {
setToast(context, context.getResources().getString(R.string.whatsapp_not_installed));
}
}
I used this function to share images it's working I hope it's work you too.
Edit
Add this dependency for converting URL to bitmap
implementation 'com.github.bumptech.glide:glide:4.14.2'
Use this function to get Image URI to share
private Uri getImageURI(Bitmap image) {
File imagesFolder = new File(getCacheDir(), "images");
Uri uri = null;
try {
imagesFolder.mkdirs();
File file = new File(imagesFolder, "shared_image.png");
FileOutputStream stream = new FileOutputStream(file);
image.compress(Bitmap.CompressFormat.PNG, 90, stream);
stream.flush();
stream.close();
uri = FileProvider.getUriForFile(this, getPackageName() + ".provider", file);
} catch (IOException e) {
Log.d("TAG", "IOException while trying to write file for sharing: " + e.getMessage());
}
return uri;
}
Use this function for share Image on WhatsApp
public static void shareOnWhatsapp(Context context, Uri uri) {
Intent intent = new Intent();
intent.setAction("android.intent.action.SEND");
intent.setPackage("com.whatsapp");
String stringBuilder = "Your String Or Message" +
context.getPackageName();
intent.putExtra("android.intent.extra.TEXT", stringBuilder);
intent.putExtra("android.intent.extra.STREAM", uri);
intent.setType("image/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
context.startActivity(intent);
} catch (Exception unused) {
Toast.makeText(context, "whatsapp not installed", Toast.LENGTH_SHORT).show();
}
}
Uses like this
findViewById(R.id.btnShare).setOnClickListener(v -> {
Glide.with(this).asBitmap().load( /*Your URL*/ "https://drinkprime.in/images/smart_water_purifier.jpg").into(new CustomTarget<Bitmap>() {
#Override
public void onResourceReady(#NonNull Bitmap resource, #Nullable Transition<? super Bitmap> transition) {
Bitmap bitmap = resource;
shareOnWhatsapp(MainActivity.this, getImageURI(bitmap));
}
#Override
public void onLoadCleared(#Nullable Drawable placeholder) {
}
});
});
It's Working now completely

Unable to open PDF file through intent programmatically in android

I have an app where on button click, access should be provided to browse and open the PDF files stored in the internal memory of the device.I tried various codes but i get an toast saying "Cannot display PDF". I don't get any errors in logs. I use android version 7.0 device. Attached my code below: please help:
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
I have included this in Oncreate:
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
This is how called the method:
linear_pdf.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pdf.setTextColor(getActivity().getResources().getColor(R.color.colorWhite));
openPdf(getContext(), Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
communication.dismiss();
}
});

Try this one...
public void openPdf(Context context, String path){
File file = new File(path);
if (file.exists()) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
PackageManager pm = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.setType("application/pdf");
Intent openInChooser = Intent.createChooser(intent, "Choose");
List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
if (resInfo.size() > 0) {
try {
context.startActivity(openInChooser);
} catch (Throwable throwable) {
Toast.makeText(context, "PDF apps are not installed", Toast.LENGTH_SHORT).show();
// PDF apps are not installed
}
} else {
Toast.makeText(context, "PDF apps are not installed", Toast.LENGTH_SHORT).show();
}
}
}
Call this method:
openPdf(getApplicationContext(), Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");

For opening one specific file:
File pdfFile = new File(Environment.getExternalStorageDirectory() + "/your_directory/" + "your_file_name" + ".pdf");
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try{
startActivity(pdfIntent);
}catch(ActivityNotFoundException e){
Toast.makeText(getContext(), "No required app", Toast.LENGTH_SHORT).show();
}
Check directory, this one works.

For opening pdf file from local storage add prefix in url.
private void openPdf(File file) {
try {
String url = file.getAbsolutePath();
String u = "file:///" + url;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(u));
startActivity(i);
} catch (Exception e) {
e.printStackTrace();
}
}

Share Image and data to Twitter in android

I ma developing one application in i have to share data and image to Twitter from my android Application.I am following http://chintankhetiya.wordpress.com/2013/07/18/sharing-text-image-in-twitter-android-example/comment-page-1/#comment-285 this.I did change consumer key and consumer secret .While Running my App one Toast message coming Login Faild .Please tell me any thing required for this

For twitter sharing you can share file directly from the twitter app if it is install and if the app is not install you can use twitter api.
Below is the code for both the things
Boolean isTwitterAppAvailable =false;
try {
Intent shareIntent = new Intent(
android.content.Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT,
"Content to share");
PackageManager pm = getPackageManager();
List<ResolveInfo> activityList = pm.queryIntentActivities(
shareIntent, 0);
for (final ResolveInfo app : activityList) {
if (app.activityInfo.name.contains("twitter")) {
final ActivityInfo activity = app.activityInfo;
final ComponentName name = new ComponentName(
activity.applicationInfo.packageName,
activity.name);
shareIntent.setClassName("com.twitter.android",
"com.twitter.android.PostActivity");
shareIntent.addCategory(Intent.CATEGORY_LAUNCHER);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
shareIntent.setComponent(name);
shareIntent.putExtra(Intent.EXTRA_TEXT,
GlobalApplication.twitter_share_msg);
if (GlobalApplication.isImageShareTwitter)
shareIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file:///sdcard/attachment.jpg"));
isTwitterAppAvailable = true;
startActivity(shareIntent);
break;
}
}
if (!isTwitterAppAvailable) {
if (isNetworkAvailable()) {
GlobalApplication.casted_image = casted_image;
// twitter web sharing using twitter4j api...
Twitt_Sharing twitt = new Twitt_Sharing(
ShowCampaignDetail.this, twitter_consumer_key,
twitter_secret_key);
twitt.shareToTwitter(
GlobalApplication.twitter_share_msg,
casted_image);
Twitter_Handler tHandler = new Twitter_Handler(
ShowCampaignDetail.this, twitter_consumer_key,
twitter_secret_key);
User user;
try {
user = tHandler.twitterObj
.showUser(tHandler.twitterObj.getId());
String url = user.getProfileImageURL();
} catch (IllegalStateException e) { // TODO
// Auto-generated
e.printStackTrace();
} catch (TwitterException e) {
e.printStackTrace();
}
} else {
Toast.makeText(ShowCampaignDetail.this,
"No Network Connection Available !!!",
Toast.LENGTH_LONG).show();
}
}
} catch (Exception e) {
e.printStackTrace();
}

Use Following code :
/*
* Share any Image.
*/
private void shareImage() {
Intent share = new Intent(Intent.ACTION_SEND);
// If you want to share a png image only, you can do:
// setType("image/png"); OR for jpeg: setType("image/jpeg");
share.setType("image/*");
// Make sure you put example png image named myImage.png in your
// directory
String imagePath = Environment.getExternalStorageDirectory()
+ "/myImage.png";
File imageFileToShare = new File(imagePath);
Uri uri = Uri.fromFile(imageFileToShare);
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(share, "Share image to..."));
}

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;
}
}
