I'm creating an app, and in this app have a button to open an PDF with a calendar with activities of user...
The PDF is in assets folder.
And the actualy code is:
private void abrirCalendario() {
AssetManager assetManager = getAssets();
File fileDir = new File(Environment.getExternalStorageDirectory().getPath() + "/");
fileDir.mkdirs();
File file = new File(fileDir, "Calendario DAERG.pdf");
String path = Environment.getExternalStorageDirectory().getPath() + "/Calendario DAERG.pdf";
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(this, getPackageName() + ".provider", new File(path));
List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = "tk.davidev.android.ews";
grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
}else {
uri = Uri.fromFile(new File(path));
}
if(!file.exists()) {
try {
InputStream in = assetManager.open("calendario_2017.pdf");
OutputStream out = new BufferedOutputStream(new FileOutputStream(file));
copyFile(in, out);
in.close();
out.flush();
out.close();
} catch (Exception e) {
}
}
intent.setDataAndType(uri, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
And the error i'm getting is:
file:///storage/emulated/0/Calendario DAERG.pdf exposed beyond app through Intent.getData()
Hi because Android from Mashmellow , I think, changes its segurity behavior such as request for permission on runtime or using FileProvider to manage URI. Now me have to give permission in some code in order to work.
Here's an example of open Intent with ACTION_VIEW in Nougat
File archivo= new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES),"excerpt_DEC.pdf");
Uri uri = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
archivo);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri,"application/pdf");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
startActivity(intent);
My example is the same as yours. I read a file from assets then, I find that file created and save it in archivo object. Later on, get an uri with FileProvider method and finally, I give permissions to intent with this line
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
I leave you this link for background knowledge about this new implementation.
https://developer.android.com/reference/android/support/v4/content/FileProvider.html
Also, I followed this anwser to read my file.pdf from asset

i'm trying to send (install) my mcpack file using this code but is is not working, minecraft support this type of extenstion to install mods (.mcpack, .mcaddon, .mcworld, .mctemplate, .modpkg how we can define mimetypes for these extensions)
please go through this image i need exactly like this https://imgur.com/14rIBvN
try {
//File path = new File(getFilesDir(), "dl");
File file = new File(path);
PackageManager manager = this.getPackageManager();
// Get URI and MIME type of file
Intent share = new Intent(Intent.ACTION_SEND);
//share.setType("image/jpeg");
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(path));
share.setPackage("com.mojang.minecraftpe");//package name of the app
startActivity(Intent.createChooser(share, "Select Minecraft to install"));
} catch (Exception e) {
Log.i(TAG, "App not found.. "+e.getMessage());
}
i did it!)
File file = new File(this.getExternalFilesDir(null), "1.mcpack");
Uri photoURI = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", file);
Intent intent = new Intent(Intent.ACTION_VIEW);
// set the content type and data of the intent
intent.setDataAndType(photoURI, "application/octet-stream");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
// start the intent as a new activity
startActivity(intent);
Open with minecraft and it will open and it will day download started and if it works it will say, If it does not work it will say, Minecraft onlu supports .mcpack, .mcworld, .mctemplate on pocket edition
I am trying to add option to update app by downloading apk, its getting installed successfully. But the problem is, app got close after installation, without prompting Open/Done screen in Nougat and above devices.
I have tried using both ACTION_VIEW and ACTION_INSTALL_PACKAGE, but no luck. Also tried with startActivityForResult instead of startActivity, still no luck.
public void installAPK() {
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
File file = new File(path + "update.apk");
if (Build.VERSION.SDK_INT < 24) {
intent.setDataAndType(Uri.fromFile(new File(path + "update.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
} else {
Uri apkURI = FileProvider.getUriForFile(
activity,
activity.getApplicationContext()
.getPackageName() + ".provider", file);
intent.setDataAndType(apkURI, "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
activity.startActivityForResult(intent, RC_INSTALL_APK);
}
Anything I missed to do?
Here's sample code of my application method to open new version
void OpenNewVersion(String location) {
Intent downloadIntent;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
String PATH = Environment.getExternalStorageDirectory() + "/Download/";
File fileLocation = new File(PATH, "app-stock.apk");
Uri apkUri = FileProvider.getUriForFile(this, "Adapters.GenericFileProvider", fileLocation);
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
downloadIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(apkUri, "application/vnd.android.package-archive");
List<ResolveInfo> resInfoList = this.getPackageManager().queryIntentActivities(downloadIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
this.grantUriPermission(packageName, apkUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
} else {
File fileLocation = new File(this.getFilesDir(), "app-stock.apk");
downloadIntent = new Intent(Intent.ACTION_VIEW);
downloadIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
downloadIntent.setDataAndType(Uri.fromFile(fileLocation), "application/vnd.android.package-archive");
}
this.startActivity(downloadIntent);
}
What i am trying is to share a file over bluetooth. I have tried below two methods to pass the file name to the ACTION_SEND intend. share activity is pop'ing up and when i touch the connected bluetooth device, i get a toast saying Bluetooth share: File Unknown file not sent. Both the method fails.
public void pushFileOverOpp(String filename) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setPackage("com.android.bluetooth");
intent.setType("audio/mp3");
File f = new File(Environment.getExternalStorageDirectory(), "images");
File sample = new File(f, "sample.mp3");
Uri u = Uri.parse(sample.toString());
intent.putExtra(Intent.EXTRA_STREAM, u);
mContext.startActivity(intent);
}
Error , Log-
OppService: URI : /storage/emulated/0/images/sample.mp3
OppService: HINT : null
OppService: FILENAME: null
OppService: MIMETYPE: audio/mp3
File f = new File(mContext.getFilesDir(), "images");
File sample = new File(f, "sample.mp3");
Uri u = FileProvider.getUriForFile(mContext,
BuildConfig.APPLICATION_ID + ".provider", sample);
intent.putExtra(Intent.EXTRA_STREAM, u);
Error, Log-
OppService: URI : content://com.example.com.test.provider/tester/images/sample.mp3
OppService: HINT : null
OppService: FILENAME: null
I have checked the android source code, This error comes when filename is null. Log also says filename is null. But i could not figure out the exact reason. Could someone Please help me out here, what is wrong with my code.
After some study i understood the problem. There were two issues-
xml tag for external storage(/sdcard/) directory was wrong in xml file.
I changed as below.
<root-path
name="root"
path="/" />
URI permission was not granted
mContext.grantUriPermission("com.android.bluetooth", u,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
After modifying with above lines of code, File share is working !
full working code-
public boolean pushFileOverOpp(String filename) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("*/*"); // supports all mime types
intent.setPackage("com.android.bluetooth"); //bluetooth package name, default opp
File folder = new File(Environment.getExternalStorageDirectory(), "images");
File file = new File(folder, filename);
if (!file.exists()) {
Logger.e("No such file " + filename + " exists!");
return false;
}
Uri u = FileProvider.getUriForFile(mContext, mContext.getPackageName() + ".provider", file);
intent.putExtra(Intent.EXTRA_STREAM, u);
mContext.grantUriPermission("com.android.bluetooth", u,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
Logger.d("Sharing file over bluetooth " + folder.toString());
mContext.startActivity(intent);
return true;
}
Thanks.
Please refer this code , it works and share the files using createChooser method.
ArrayList<Uri> arrayList2 = new ArrayList<>();
String MEDIA_PATH = new String(Environment.getExternalStorageDirectory() +
"/NewCallLogs/audio.mp3");
File files = new File(MEDIA_PATH);
Uri u = Uri.fromFile(files);
arrayList2.add(u);
Intent share = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
share.setData(Uri.parse("mailto:"));
share.setType("audio/mpeg");
share.putExtra(android.content.Intent.EXTRA_STREAM, arrayList2);
try {
startActivity(Intent.createChooser(share, "Share..."));
// getActivity().finish();
Log.i("Finished sharing.", "");
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(getActivity(), "nothing shared.", Toast.LENGTH_SHORT).show();
}
For sharing the file only in bluetooth
ArrayList<Uri> arrayList2 = new ArrayList<>();
String MEDIA_PATH = new String(Environment.getExternalStorageDirectory() +
"/NewCallLogs/audio.mp3" );
File files = new File(MEDIA_PATH);
Uri u = Uri.fromFile(files);
arrayList2.add(u);
Intent share = new Intent(android.content.Intent.ACTION_SEND);
share.setData(Uri.parse("mailto:"));
share.setType("audio/mpeg");
share.setPackage("com.android.bluetooth");
share.putExtra(android.content.Intent.EXTRA_STREAM, arrayList2);
startActivity(share);
I'm trying to open a file using another app, i.e. opening a .jpg with Gallery, .pdf with Acrobat, etc.
The problem I'm having with this is when I try to open the file in the app, it only opens the chosen app instead of opening the file within the app. I tried following Android open pdf file via Intent but I must be missing something.
public String get_mime_type(String url) {
String ext = MimeTypeMap.getFileExtensionFromUrl(url);
String mime = null;
if (ext != null) {
mime = MimeTypeMap.getSingleton().getMimeTypeFromExtension(ext);
}
return mime;
}
public void open_file(String filename) {
File file = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS), filename);
// Get URI and MIME type of file
Uri uri = Uri.fromFile(file).normalizeScheme();
String mime = get_mime_type(uri.toString());
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(uri);
intent.setType(mime);
context.startActivity(Intent.createChooser(intent, "Open file with"));
}
As far as I can tell, it returns the right URI and MIME type:
URI: file:///storage/emulated/0/Download/Katamari-ringtone-985279.mp3
MIME: audio/mpeg
Posting my changes here in case it can help someone else. I ended up changing the download location to an internal folder and adding a content provider.
public void open_file(String filename) {
File path = new File(getFilesDir(), "dl");
File file = new File(path, filename);
// Get URI and MIME type of file
Uri uri = FileProvider.getUriForFile(this, App.PACKAGE_NAME + ".fileprovider", file);
String mime = getContentResolver().getType(uri);
// Open file with user selected app
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(uri, mime);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}
I used this piece of code and it worked perfectly fine on android 6 and below not tested on the higher version
public void openFile(final String fileName){
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory()
.getAbsolutePath()+ File.separator+"/Folder/"+fileName));
intent.setDataAndType(uri, "audio/mpeg");
startActivity(intent);
}
[This question may be duplicate, but i din't find what i am looking for]
[Read]How can we open files like ppt, doc, pps, rtf, etc. in Android?
I am having PPT files. In my app, i have a list view which display the PPT file list available in my private app folder. In click of particular file, i want to open corresponding PPT file for reading in my App.
The App which i am creating is just like collection of PPTs and reading them one by one.
Please provide any API/Example/Links.
You need to use other application to open your ppt files , Make sure that file location you are providing is accessible to other application. Try with following :
final Uri uri = Uri.fromFile(file);
final Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, "application/vnd.ms-powerpoint");
PackageManager pm = getPackageManager();
List<ResolveInfo> list = pm.queryIntentActivities(intent, 0);
if(list.size() > 0)
startActivity(context, intent);
Available application will be shown to user and user can choose application which can open.
private void openPPT(final String path) {
File file = new File(path);
Uri uri ;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
} else {
uri = Uri.fromFile(file);
}
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setDataAndType(path, "application/vnd.ms-powerpoint");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "Application not found", Toast.LENGTH_SHORT).show();
}
}
