To send the email the method for the button is;
public void buttonSendEmailClicked(View view) {
File file = saveFileToShare();
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("application/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Check Out MyPic");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Taken With Android!");
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivityForResult(Intent.createChooser(emailIntent, "Send mail..."), interstitial_request);
}
The saveFileToShare element is this;
public File saveFileToShare() {
try
{
File fileImage = new File(Environment.getExternalStorageDirectory() + "/DCIM/Camera/attachment.png");
if(!fileImage.exists())
{
fileImage.delete();
}
editorImage.setDrawingCacheEnabled(true);
Bitmap bitmap = editorImage.getDrawingCache();
fileImage.createNewFile();
FileOutputStream ostream = new FileOutputStream(fileImage);
bitmap.compress(CompressFormat.PNG, 100, ostream);
ostream.close();
editorImage.invalidate();
editorImage.setDrawingCacheEnabled(false);
return fileImage;
}
catch (Exception e)
{
System.out.print(e);
e.printStackTrace();
return null;
}
}
Saving the image works fine, the save code is;
public void buttonSaveImageClicked(View view) throws IOException {
editorImage.setDrawingCacheEnabled(true);
Bitmap bitmap = editorImage.getDrawingCache();
SaveLayoutToFile saveImage = new SaveLayoutToFile(this, bitmap, editorImage);
String filePath = Environment.getExternalStorageDirectory() + "/DCIM/Camera/wonkydog";
saveImage.execute(filePath);
}
I need to set the email code to grab the image and attach to email.
At the moment when I press the email button it just returns to the title screen without doing anything else.
If I comment out this line
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
Then it opens the mail send dialogue, but without attachment of course...
I found the answer, rather than using the emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
I replaced it with;
emailIntent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(EditorActivity.this, "com.myapp.myappname.provider", file));
It now works correctly!

I have upgraded to android 11. I am having an issue downloading PDF files.
I have used this code:
private void createFile(Uri pickerInitialUri, String title) {
Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/pdf");
intent.putExtra(Intent.EXTRA_TITLE, title);
// Optionally, specify a URI for the directory that should be opened in
// the system file picker when your app creates the document.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, pickerInitialUri);
}
startActivityForResult(intent, CREATE_FILE);
}
The file is created but the file is empty. I am still unable to save the downloaded pdf file.
I used to use DownloadManager request to download the pdf file from web.
DownloadManager downloadManager = (DownloadManager) this.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(uri);
if (SDK_INT > Build.VERSION_CODES.Q) {
// Uri uri1 = Uri.fromFile(new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "")); //before android 11 this was working fine
// Uri uri1 = Uri.fromFile(new File(getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS), ""));
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(true).setTitle(title + strDate + ".pdf")
.setDescription(description)
//.setDestinationUri(uri1) // before android 11 it was working fine.
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, title + strDate + ".pdf") // file is not saved on this directory.
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);//to show the DOWNLOAD notification when completed
// createFile(uri , title + strDate + ".pdf"); // for new scoped storage
} else {
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(true).setTitle(title + strDate + ".pdf")
.setDescription(description)
.setDestinationInExternalPublicDir(FileUtils.downloadPdfDestination(), title + strDate + ".pdf")
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //to show the DOWNLOAD notification when completed
}
long PDF_DOWNLOAD_ID = downloadManager.enqueue(request);```
ACTION_CREATE_DOCUMENT is used to create a new document. If one already existed, it will be overwritten. If you want to view an existing document, use ACTION_VIEW.
Of course none of the code you posted actually downloads a PDF. If you need help with that, post your DownloadManager code.
Check this code snippet:
override fun startDownload(url: String, onError: (e: Exception) -> Unit) {
try {
val request = DownloadManager.Request(Uri.parse(url))
request.setDestinationInExternalPublicDir(
Environment.DIRECTORY_DOWNLOADS,
UUID.randomUUID().toString()
)
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_ONLY_COMPLETION)
(context.getSystemService(DOWNLOAD_SERVICE) as DownloadManager).enqueue(request)
} catch (e: Exception) {
e.printStackTrace()
onError.invoke(e)
}
}
It's working fine on Android 11 by using DownloadManger API.
Use below code to download & view pdf.
First you need to apply rxjava dependency for background task.
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
Don't forgot to check WRITE_EXTERNAL_STORAGE permission before call below method. Also check INTERNET permission as well.
Then use below method to perform operation in background.
private void downloadAndOpenInvoice() {
mDialog.show();
Observable.fromCallable(() -> {
String pdfName = "Invoice_"+ Calendar.getInstance().getTimeInMillis() + ".pdf";
String pdfUrl = "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf";
File file = CommonUtils.downloadFile(mActivity, pdfUrl, pdfName,mDialog);
return file;
}).subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(file -> {
CommonUtils.viewPdf(file, mActivity, mDialog);
});
}
To download file from url use below snippet
public static File downloadFile(Activity mActivity, String url, String fileName, CustomDialog mDialog) {
// write the document content
File fileDir = new File(CommonUtils.getAppDir(mActivity, "Invoice")); //Invoice folder inside your app directory
if (!fileDir.exists()) {
boolean mkdirs = fileDir.mkdirs();
}
File pdfFile = new File(CommonUtils.getAppDir(mActivity, "Invoice"), fileName); //Invoice folder inside your app directory
try {
URL u = new URL(url);
URLConnection conn = u.openConnection();
int contentLength = conn.getContentLength();
DataInputStream stream = new DataInputStream(u.openStream());
byte[] buffer = new byte[contentLength];
stream.readFully(buffer);
stream.close();
DataOutputStream fos = new DataOutputStream(new FileOutputStream(pdfFile));
fos.write(buffer);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
if (mDialog.isShowing()) {
mDialog.dismiss();
}
Toast.makeText(mActivity, "Something wrong: " + e.toString(), Toast.LENGTH_LONG).show();
}
return pdfFile;
}
for app directory
public static String getAppDir(Context context, String folderName) {
return context.getExternalFilesDir(null).getAbsolutePath() + File.separator + folderName + File.separator;
}
Use below code to view pdf
public static void viewPdf(File pdfFile, Activity mActivity, CustomDialog mDialog) {
Uri uri = FileProvider.getUriForFile(mActivity, mActivity.getApplicationContext().getPackageName() + ".provider", pdfFile);
// Setting the intent for pdf reader
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
pdfIntent.setDataAndType(uri, "application/pdf");
//pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
mActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
if (mDialog.isShowing()) {
mDialog.dismiss();
}
}
});
mActivity.startActivity(pdfIntent);
Log.e("Invoice - PDF", pdfFile.getPath());
} catch (ActivityNotFoundException e) {
mActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
if (mDialog.isShowing()) {
mDialog.dismiss();
}
}
});
e.printStackTrace();
Log.e("Invoice - PDF", "Can't read pdf file");
Toast.makeText(mActivity, "Can't read pdf file", Toast.LENGTH_SHORT).show();
}
}
I have checked the uri, the file saved is a bitmap and its returning file. But the image which shows during sharing is not valid. Gmail says it could not attach the attachment, messages app could not load the image.
Text sharing is working fine.
I am new to Android and is having problem sharing image through share intent. I have googled alot, tried various things but still could not find the solution.
public static void shareWallpaper(Context context, int wallpaperResourceId) {
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), wallpaperResourceId);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/wallpaper" + String.valueOf(wallpaperResourceId) + ".jpg";
OutputStream out = null;
File file = new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(file.getPath()));
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
context.startActivity(Intent.createChooser(shareIntent, "برنامه مورد نظر خود را انتخاب کنید"));
}
I am developing and android blog application where I want to share my current blog page screenshot.I try but it showing file format is not supported..please help me to find my error..Thanks in advance
MyAdapter.java
sendImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Bitmap app_snap = ((BitmapDrawable)movie_image.getDrawable()).getBitmap();
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/SaveImg";
System.out.println("****FILEPATH **** : " + file_path);
File imagePath = new File(Environment.getExternalStorageDirectory() + "/scr.png");
FileOutputStream fos;
try {
fos = new FileOutputStream(imagePath);
System.out.println("****FILEPATH1 **** : " + file_path);
app_snap.compress(Bitmap.CompressFormat.PNG, 200, fos);
System.out.println("****FILEPATH2 **** : " + file_path);
fos.flush();
fos.close();
}
catch (IOException e) {
System.out.println("GREC****** "+ e.getMessage());
}
Intent sharingIntent = new Intent();
Uri imageUri = Uri.parse(imagePath.getAbsolutePath());
sharingIntent.setAction(Intent.ACTION_SEND);
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
context.startActivity(sharingIntent);
}
});
Here is the code that allowed my screenshot to be stored on an SD card and used later for whatever your needs are:
First, you need to add a proper permission to save the file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
And this is the code (running in an Activity):
private void takeScreenshot() {
Date now = new Date();
android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);
try {
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";
// create bitmap screen capture
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
File imageFile = new File(mPath);
FileOutputStream outputStream = new FileOutputStream(imageFile);
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
openScreenshot(imageFile);
} catch (Throwable e) {
// Several error may come out with file handling or DOM
e.printStackTrace();
}
}
And this is how you can open the recently generated image:
private void openScreenshot(File imageFile) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
Uri uri = Uri.fromFile(imageFile);
intent.setDataAndType(uri, "image/*");
startActivity(intent);
}
If you want to use this on fragment view then use:
View v1 = getActivity().getWindow().getDecorView().getRootView();
instead of
View v1 = getWindow().getDecorView().getRootView();
on takeScreenshot() function
Note:
This solution doesn't work if your dialog contains a surface view. For details please check the answer to the following question:
Android Take Screenshot of Surface View Shows Black Screen
if u have any doubt please go through this link
You can get the Bitmap of your screen view inside your layouts. Where view will be your layout views like Linear or RelativeLayout
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap returnedBitmap = view.getDrawingCache();
then have to convert into byte[] so that you can send with the Intent like this following:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
returnedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
and send data with Intent like this:
Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("bitmap_",byteArray);
get Intent on your SecondActivity like this:
byte[] byteArray = getIntent().getByteArrayExtra("bitmap_");
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
I am trying to create file in internal storage and then send it via email in Android.
However, I still get file not found or similar errors.
Please, help!
String FILENAME = "TestFile.txt";
Sending file by button click
btnSendFile.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
File gpxfile = getFile();
Uri path = Uri.fromFile(gpxfile);
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
Context context = v.getContext();
String email = "MYEMAILHERE";
i.putExtra(Intent.EXTRA_EMAIL, new String[]{email});
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "Text");
i.putExtra(Intent.EXTRA_STREAM, path);
context.startActivity(Intent.createChooser(i, context.getString("Sending...")));
}
});
}
Creating file in internal storage
private void createTestFile() {
try {
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_APPEND);
fos.write("Your content".getBytes());
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Get file function. Return File if file exists
private File getFile() {
return new File(getFilesDir() + "/" + FILENAME);
}
Maybe you need to make
Context.openFileOutput(FILENAME, Context.MODE_APPEND);
Instead of that one you used? I think someone had similiar problem over here: android what is wrong with openFileOutput?
i'm trying to send images from my app, but it only sends one image (the one mentioned in the code below image_intro.
i want the app to share whatever image the user chooses.
Here is the code i used:
// Share event start
final Button share = (Button) findViewById(R.id.share);
share.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.image_intro);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/LatestShare.jpg";
OutputStream out = null;
File file=new File(path);
try {
out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
path=file.getPath();
Uri bmpUri = Uri.parse("file://"+path);
Intent shareIntent = new Intent();
shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/jpg");
startActivity(Intent.createChooser(shareIntent,"Share with"));
}
});
im counting in your help friends, thanks
i managed to solve it by adding these two lines:
ImageView image = (ImageView) findViewById(R.id.backgroundPreview);
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
