When I click the share button, it opens and shows some apps, but I click one app, for eg, WhatsApp it open and I choose the contact but when clicking the send button it shows "file can't be send". where I made a mistake, please help me to solve this code.
here I attached code for the share button.
//get an image from imageview
Drawable drawable = imageView.getDrawable();
Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();
//sharing image
try {
File file = new File(MainActivity.this.getExternalCacheDir(), "myImage.png");
FileOutputStream fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 80, fOut);
fOut.flush();
fOut.close();
file.setReadable(true, false);
//sharing intent
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file);
intent.setType("image/png");
startActivity(Intent.createChooser(intent, "Share via"));
} catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(MainActivity.this, "File not Found", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
Try adding
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
here is my android manifest file,

i am using this code to run a camera intent to take a photo. All being taken from HERE step by step (full sized camera option)
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(getActivity(), "com.example.android.fileprovider", photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(imageFileName, ".jpg",storageDir);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
Toast.makeText(getActivity(), mCurrentPhotoPath, Toast.LENGTH_SHORT).show();
return image;
}

A little surprising since the file "shell" is there(at this location).
I fount THIS thread but i cant understand a thing...can you explain it humanlike? Any solution is welcome! Its an important project and i need to finish as much as possible and this is a huge stop.
In your files_path.xml, you need to replace com.example.package.name with your apps package name, as explained on developers site.
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Android/data/com.example.terrormachine.swipeapp/files/Pictures" />
</paths>
Also add camera permission in your AndroidManifest.xml file.
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera"
android:required="true" />
I think you are missing "uses-feature android:name="android.hardware.camera" android:required="true"" in your manifest.
I have a problem in my android app while trying to create a pdf file from view of app.
W/System.err: java.io.FileNotFoundException: /storage/emulated/0/Documents/MyList/MyList.pdf: open failed: ENOENT (No such file or directory)
I had an error such like above. What am I missing there?
How can I handle it? Can you help me? Thanks.

Please any one help me i was so Straggled about it.
Onreceive method will crash app at context.startActivity(Intent.createChooser(sendIntent, "Send"));
It works fine in oncreate method but do not work in broadcastreceiver class.
Can anybody knows reason. I am new android programmer.
Thanks in advance.
public class SMSReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
takePictureNoPreview(context);
String imagePath="test.jpeg";
Intent sendIntent = new Intent(Intent.ACTION_SEND);
// sendIntent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
sendIntent.putExtra("sms_body", "I Send you pic.");
sendIntent.putExtra("address", phoneNumber);
sendIntent.setType("image/png");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(dataFile));
// context.startActivityForResult(sendIntent, 1);
context.startActivity(Intent.createChooser(sendIntent, "Send"));
// context.startActivity(sendIntent);
}
}
}
public void takePictureNoPreview(Context context){
// open back facing camera by default
Camera myCamera= Camera.open();//openFrontFacingCameraGingerbread();
if(myCamera!=null){
try{
//set camera parameters if you want to
//...
// here, the unused surface view and holder
SurfaceView dummy=new SurfaceView(context);
myCamera.setPreviewDisplay(dummy.getHolder());
myCamera.startPreview();
myCamera.takePicture(null, null, photoCallback);
} catch (IOException e) {
e.printStackTrace();
}finally{
// myCamera.close();
}
}else{
Toast toast = Toast.makeText(context, "No front Facing camera", Toast.LENGTH_LONG);
toast.show();
}
}
Camera.PictureCallback photoCallback = new Camera.PictureCallback() {
public void onPictureTaken(byte[] data, Camera camera) {
// Save the image JPEG data to the SD card
FileOutputStream fos = null;
// camera.startPreview();
bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
StudentDemo.iView.setImageBitmap(bmp);
try {
fos = new FileOutputStream(dataFile,true);
fos.write(data);
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();

Try:
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra("sms_body", "I Send you pic.");
sendIntent.putExtra("address", phoneNumber);
sendIntent.setType("image/png");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(dataFile));
sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(Intent.createChooser(sendIntent, "Send"));
Whenever launching an Activity from outside a UI related context (like a Service or a BroadcastReceiver), you need to attach the FLAG_ACTIVITY_NEW_TASK to the intent.
This function is used to save image on sdcard (I have tested it on the emulator only):
public String SaveImage(String URL,String imagename){
Bitmap bitmap = null;
InputStream in = null;
String path = Environment.getExternalStorageDirectory().toString();
File dir = new File(path + "/bh");
if(!dir.exists())
new File(path + "/bh").mkdir();
Log.i("in save()", "after file");
File mImageFile = new File(path+"/bh/"+imagename);
if(mImageFile.exists())
Toast.makeText(mContext, "Saved", Toast.LENGTH_LONG).show();
try{
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
FileOutputStream out = new FileOutputStream(mImageFile);
bitmap.compress(CompressFormat.JPEG, 100,out);
out.flush();
out.close();
in.close();
return imagename+".jpg";
}catch(IOException ex){
Log.e("==== Error in saving image ====",ex.getMessage());
return "";
}
}
I have added the required permissions like below :

You also need to use the Internet permission since you're connecting to the internet.
<uses-permission android:name="android.permission.INTERNET" />
Does your emulator support SDCard ?
