I am about to build an app like deezer using flutter https://play.google.com/store/apps/details?id=deezer.android.app now for I have 2 question.
Is there any library for online audio streaming which may give the possibility to download the app
How can I store my audio files in a private / hidden folder such as folder created using vault app in case of download https://play.google.com/store/apps/details?id=com.netqin.ps
Thanks for your help
To stream audio you can use this library:
AudioPlayers
To keep your files safe you can use the Sandbox folder in iOS and getExternalFilesDir in Android.
You can find an example of how to implement the saving of the file over here:
Saving data to Local Storage in Flutter
I remind you that SOF is to show what you've done so far, some of your progress, examples, etc so we can help you with that and not how to build an entire app.
I am new to phoneGap. I am creating a dummy app to upload an audio file from iOS/android device on local server. So I was wondering if there is a way to open the audio gallery and select the required audio file to upload. Similar to an image gallery.
Is it possible to open audio list and select necessary audio file? If not, what is the alternative?
As far as I remember, you cannot reach the pictures and audio files stored in the media gallery. Therefore, you may need to implement your own native plugin and call the appropriate methods from your JavaScript code.
You can capture audio/image by using Capture plugin of Phonegap. Check this out Capture Plugin
You can perform basic File operations as well. Check this out File Plugin
For your situation, you have to implement native interface which can be accessed by your JavaScript code. This would be an alternative way for it. If you desire to create your own plugin, please have a look at Plugin Development Guide. This might be helpful.
Well I have implemented code using file plugin which will iterate through all the folders recursively to find all the image (created this as I needed multi selection approach which is not directly provided by cordova) . You can modify the extension of image (search) i.e png,jpeg etc with audio extension.
With this code you will get the path of audio files and you can make use of filetransfer to upload it on server
Hope it helps you
I'm creating an Android app that will handle collections of image files.
I'm looking for an archive format (and library) similar to .zip or .tar that meets these requirements:
Open source
Allows extraction of a single file without extracting
all files
Capable of containing image and text (probably json) files
I'm looking for something that is well supported on Android. Something that works for Android and IOS would be a plus.
What about Gzip? Open source and it has native support on Android.
For iPhone, you could use the ZipArchive library, though it may also have native support. (Search the SDK, I don't know how!)
In my app,I want to make sure user can record his sound and sent to other user to listen to it.
In android platform I choose .amr ,it's not too big and easy to record.
Then I realized I should make sure my ios user can chat with my android user,but .amr seems not support in ios(after v4.3).
So is there a certain audio file format that can use between android and ios platform?
Or I have to let my Server to do the Transcoding job?
Both android and iOS should be able to handle mp3 files.
You can encode to mp3 on the device using various open source projects (could be a combination of steps).
I would personally go for a server-side encoding/conversion, because too many things can go wrong (especially on all the various Android versions and devices)
At last we use amr. Ios client do the decode job.
I am curious how to create a simple PowerPoint presentation viewer for Android. I am focusing on the Office 2003 and 2007 formats (which means .ppt and .pptx). How do I read .ppt or .pptx files and show them like a picture slideshow on my Android app?
Well that's a loaded question. Are you seriously thinking someone will write down the whole process for you? Have you done any research?
I'd start by seeing if there are any java libraries for working with .ppt files. Secondly, I'd see if I can use it in Android. Then I'd use the Android SDK to create the app using the said library.
Easy.
