I'm adding a notification to my android project:
mBuilder.setContentTitle("title");
mBuilder.setContentText("Text");
mBuilder.setSmallIcon(R.drawable.icon);
mBuilder.setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE);
mBuilder.setSound(Uri.parse("android.resource://com.my.package/" + R.raw.sound));
mBuilder.setOnlyAlertOnce(true);
Now, I would like a "settings view" where the user can decide if he/she wants vibrating or sound.
How should I store this setting and update setDefaults and setSound?
SharedPreferences is a good place to start.
From #dsandler, I give you an example as a little bit more detail:
builder = new NotificationCompat.Builder(this).setContentTitle(contentTitle).setContentText(contentText).setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true).setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
.setStyle(new NotificationCompat.BigTextStyle().bigText(contentText));
int notificationDefault = NotificationCompat.DEFAULT_SOUND;
// Check vibrate
boolean isVibrate = mPreferences.getBoolean(mKeyPrefNotifications[1], true);
if (isVibrate) {
notificationDefault = notificationDefault | NotificationCompat.DEFAULT_VIBRATE;
}
// Check light
boolean isLight = mPreferences.getBoolean(mKeyPrefNotifications[2], true);
if (isLight) {
notificationDefault = notificationDefault | NotificationCompat.DEFAULT_LIGHTS;
}
// Check sound
Uri sound = null;
if (!mPreferences.contains(mKeyPrefNotifications[3])) {
sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
} else {
String soundPref = mPreferences.getString(mKeyPrefNotifications[3], "");
if (soundPref.isEmpty()) {
sound = null;
} else {
sound = Uri.parse(soundPref);
}
}
builder.setDefaults(notificationDefault);
builder.setSound(sound);

I'm trying to update my app to work with androids new scoped storage rules in Android 10 and up, but am having the hardest time with it. I know I need to rebuild my app with new versions of java, but I just want to get it to work while I study and learn enough to do so. In a nutshell, I really need help. I have read so many different ways to make scoped storage work, and everybody seems to be doing it differently.
Just for clarification, what I am trying to do with the uri is both display in an imageview, then upload to database.
This code is working to take a picture and select images and videos in android 9, but in android 10, it only works when camera component captures a picture or a video. When a user selects an image or video from file, it returns a null pointer exception. Because I am pretty sure the error is in how I am dealing with the different chooser intents, I have shown the on result code first.
I have been unable to find a clear example of how to retrieve a usable image or video uri in android 10. If anybody can help, I would really appreciate it. I know I have much to learn.
if ((new java.io.File(_filePath)).exists()){
} else {
_filePath = vidfile.getAbsolutePath();
if ((new java.io.File(_filePath)).exists()){
} else {
ArrayList<String> _filePath_1 = new ArrayList<>();
if (_data != null) {
if (_data.getClipData() != null) {
for (int _index = 0; _index < _data.getClipData().getItemCount(); _index++) {
ClipData.Item _item = _data.getClipData().getItemAt(_index);
_filePath_1.add(FileUtil.convertUriToFilePath(getApplicationContext(),
_item.getUri()));
}
}
else {
_filePath_1.add(FileUtil.convertUriToFilePath(getApplicationContext(),
_data.getData()));
}
}
_filePath = _filePath_1.get((int)0);
}
}
Just in case I am wrong, here is the code for the click event to launch the chooser...
SimpleDateFormat date1 = new SimpleDateFormat("yyyyMMdd_HHmmss");
String fileName1 = date1.format(new Date()) + ".jpg";
picfile = new
File(getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_DCIM).getAbsolutePath() +
File.separator + fileName1);
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri _uri_camr1 = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
_uri_camr1 = FileProvider.getUriForFile(getApplicationContext(),
getApplicationContext().getPackageName() + ".provider", picfile);
}
else {
_uri_camr1 = Uri.fromFile(picfile);
}
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, _uri_camr1);
takePictureIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
SimpleDateFormat date2 = new SimpleDateFormat("yyyyMMdd_HHmmss");
String fileName2 = date2.format(new Date()) + ".mp4";
vidfile = new
File(getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_DCIM).getAbsolutePath() +
File.separator + fileName2);
Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
Uri _uri_camr2 = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
_uri_camr2 = FileProvider.getUriForFile(getApplicationContext(),
getApplicationContext().getPackageName() + ".provider", vidfile);
}
else {
_uri_camr2 = Uri.fromFile(vidfile);
}
takeVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, _uri_camr2);
takeVideoIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
contentSelectionIntent.setType("*/*");
contentSelectionIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Intent[] intentArray = new Intent[]{ takePictureIntent, takeVideoIntent};
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
chooserIntent.putExtra(Intent.EXTRA_TITLE, "Choose an action");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivityForResult(chooserIntent, REQ_CD_CAMR);
try this code. it copies the selected file to scoped storage and gives you the final path of scoped storage from where you can access it. try it out & let me know if you face any problem.
android.net.Uri sharedFileUri = android.net.Uri.fromFile(new java.io.File(_filepath));
java.io.FileInputStream input = null;
java.io.FileOutputStream output = null;
try {
String filePath = new java.io.File(getCacheDir(), "tmp").getAbsolutePath();
android.os.ParcelFileDescriptor pfd = getContentResolver().openFileDescriptor(sharedFileUri, "rw");
if (pfd != null) {
java.io.FileDescriptor fd = pfd.getFileDescriptor();
input = new java.io.FileInputStream (fd);
output = new java.io.FileOutputStream (filePath);
int read;
byte[] bytes = new byte[4096];
while ((read = input.read(bytes)) != -1) {
output.write(bytes, 0, read);
}
java.io.File sharedFile = new java.io.File(filePath);
String finalPath = sharedFile.getPath(); // this will provide you path to scoped storage. use this final path to access the selected file from scoped storage.
}
}catch(Exception ex) {
android.widget.Toast.makeText(this, ex.toString(), android.widget.Toast.LENGTH_SHORT).show();
} finally {
try {
input.close();
output.close();
} catch (Exception ignored) {
}
}
I have app in xamarin form where i am accessing webview for video call. Everything is working fine just i need to know how i can switch back/front camera during call? as when video call start front camera open by default.
Code for initializing video call
function initializeLocalMedia(options, callback) {
if(options) {
options['audio'] = true;
if(options['video'])
options['video'] = true;
} else {
options['audio'] = true;
options['video'] = false;
}
// Get audio/video stream
navigator.getUserMedia(options, function(stream) {
// Set your video displays
window.localStream = stream;
myapp.setMyVideo(window.localStream)
if(callback)
callback();
}, function(err) {
console.log("The following error occurred: " + err.name);
alert('Unable to call ' + err.name)
});
}
Going straight to code then it should look like:
Camera.CameraInfo camInfo = new Camera.CameraInfo ();
for (int i = 0; i < Camera.NumberOfCameras; i++) {
Camera.GetCameraInfo (i, camInfo);
if (camInfo.Facing == CameraFacing.Front){
try {
return Camera.Open(i);
} catch (Exception e) {
// log or something
}
}
}
return null;
What we are doing is iterating over the hardware and then check to match the front camera, if it match then do the things. Same is true for back camera too
I am working on Encryption,Decryption in swift OpenSSl AES-256-CBC. I have checked with many third- party libraries or pods i.e. CryptoSwift and many others. But I am always getting HMAc is Not valid from Php back end team.
Where as in android they have done this:
Following is my android method:
public EncryptedData encrypt(Object data) throws Exception {
String text;
if (data instanceof String) {
text = String.valueOf(data);
} else {
text = (new Gson()).toJson(data);
}
if (!this.doAction) {
return new EncryptedData(text, "");
} else {
this.ivspec = new IvParameterSpec(this.getIV1().getBytes());
this.keyspec = new SecretKeySpec(this.getKey1().getBytes(), "AES");
if (text != null && text.length() != 0) {
byte[] encrypted;
try {
this.cipher.init(Cipher.ENCRYPT_MODE, this.keyspec, this.ivspec);
encrypted = this.cipher.doFinal(this.padString(text).getBytes());
} catch (Exception var5) {
throw new Exception("[encrypt] " + var5.getMessage());
}
String encryptedData = new String(Base64.encode(encrypted, Base64.DEFAULT))
.replace("\n", "");
SecretKeySpec macKey = new SecretKeySpec(getKey1().getBytes(), "HmacSHA256");
Mac hmacSha256 = Mac.getInstance("HmacSHA256");
hmacSha256.init(macKey);
hmacSha256.update((Base64.encodeToString(getIV1().getBytes(), Base64.DEFAULT).trim() + encryptedData.trim()).getBytes());
byte[] calcMac = hmacSha256.doFinal();
return new EncryptedData(encryptedData, bytesToHex(calcMac));
} else {
throw new Exception("Empty string");
}
}
}
Any one know how this will works in iOS.
Any help will be appreciated.
Thanks
Here is a simple HMAC implement in Swift 4:
0xa6a/HMAC
No third-party library is needed. Just create a bridging header and import <CommonCrypto/CommonCrypto.h> in it.
Have a try and happy coding.
HI i have implemented push notification in my application, serer is sending notification but not receiving at my end.

break;
case PushNotificationType.Toast:
notificationContent = e.ToastNotification.Content.GetXml();

// Setting the cancel property prevents the notification from being delivered. It's especially important to do this for toasts:
// if your application is already on the screen, there's no need to display a toast from push notifications.

So how can i confirm that there is no issue in my implementation or there is issue from server end.
There are couple of steps you can take to debug this problem:-
There is broadcast and sending notification, using notification hub, option available on azure portal(you can do from VS also from left side server explorer). When you did this there is a log that will show you whether a notifications sent successfully or not.
First just delete all your registrations with notification hub and for very new registration check is your device getting registered with correct tags/channel uri or not(this you cad do from server explorer too)
Make sure you are sending/registering the correct templates that are corresponding to WNS service.
make sure you are using WNS service this different from what is for
WP8 silverlight one.
You can see the errors just at the bottom of this page if any.
There is option for device registrations from where you can alter the registrations.
How would i go about caching sound assets in Flex, I load the sounds for play via:
private function set_streamingMedia(mediaURL:String) : void {
var req:URLRequest = new URLRequest(mediaURL);
if (streamChannel) {
streamChannel.stop()
}
auth_play(req);
}
private function auth_play(reqestURL:URLRequest) : void {
stream = new Sound();
var credsHeader:URLRequestHeader = new URLRequestHeader("Authorization", "Basic " + credentials);
reqestURL.requestHeaders.push(credsHeader);
var context:SoundLoaderContext = new SoundLoaderContext(1000, true);
stream.load(reqestURL, context);
timer = new Timer(100);
timer.addEventListener(TimerEvent.TIMER, mediaPositionChange);
play();
}
private function play():void{
if(isPaused){
streamChannel = stream.play(trackPosition);
timer.start();
isPaused = false;
}
else{
if (streamChannel) {
stop();
}
streamChannel = stream.play();
timer.start();
isPaused = false;
}
ChangeVolume();
}
I am on the playbook, so I can save it in a directory, put it in as a BLOB on SQLite (seems like a terrible idea) - Ideas would be much appreciate.
Also want to thank all the people here who have been taking the time to teach me Flex :) - you guys are better than the book I spent money on!
