Showing File Upload Progress To User


Does anyone have a recommendation on how to visually show progress of uploading a large file to a web server? My app needs to upload one photo at a time, as directed by the user. Images are about 200kb.

I don't want to put up a progress dialog and block the user from further interaction while the upload is in progress. Looks like i can:

Have a service upload the photo, and post status updates to the notification bar.
Upload through service (or bg thread), but post status updates to some in-app notification indicator.

I'm wondering if #1 is more standard, i like the idea of putting off updates to the notifcation bar so it's separated from my main app. I don't really want to build some global upload widget that has to be displayed on each activity my user navigates to.

Can User Upload Apps To Phone Without Google / Operator Intervention

I am new to android and would like to understand the concept. Some beginners questions. Is android truly open in the sense that one can you distribute apps without having to pay google / operator (or anyone else)?

Can the user upload apps to the phone without google / operator intervention (for example by going directly to a site)? How is the upload actually done?

Will there automatically be google ads in the android application or is this controlled by the app developer / user?

Allow File Upload In Webview

For example, http://imgur.com. In the stock browser on an android phone you can press the "browse" button on imgur.com and navigate to a photo you wish to upload. This works great in the browser. Is there something i should set to true to allow this in a webview?

Publishing - Upload Update To Market - Getting Error - The File Is Invalid

I have an app which i have just updated to froyo to take advantage of the move to sd card feature. I am now trying to upload the update to the market but i keep getting the following error: "the file is invalid: w/resourcetype( 7193): bad string block: last string is not 0- terminated error getting 'android:label' attribute: attribute is not a string value". I changed the value in the manifest from "android:label="@string/app_name" " to "android:label="test" " and uploaded it, then it started complaining about the icon, saying that it wasn't a string.

The application part of my manifest is shown below and i'm properly confused. The app compiles into an apk, it even installs and runs fine on my n1 (installing from sd card) it just won't upload to the market.

Code:.

Samsung I7500 - Can't Upload Big File To Internal Sd / Fix It

I have one issue with my galaxy - i can't upload big files. It just drops a usb connection. For example i'm trying to upload something like 100-200mb file and it just drops and reconnects in a few minutes without uploading it correctly.

Currently i'm using linux, but it has the very same issue on windows (tried that already)

Any ideas? I have usb debugging on, tried without it but no difference

P. S. : This issue occurred in 1. 5 and 1. 6, just annoyed me enough to start looking for a solution.

Show Progress Bar In Notification When Uploading Image

I'd like my app to upload an image to a web server. That part works.

I'm wondering if it's possible to somehow show the progress of the upload by entering an entry in the "notification bar". I see the facebook app does this.

When you take a picture and choose to upload, the app lets you continue on, and somehow puts the picture upload notifications in a progress bar in the notification bar. I think that's pretty slick. I guess they spawn a new service or something to handle the upload and update that progress bar in the notification bar every so often.

Motorola Droid - Download Progress Bar Automatically Appeared When Click On Adobe Flash 10 / What To Do

I went into the market recently to try and download adobe flash 10. When i clicked on it to go into the app. Instead of an install button, a download progress bar automatically appeared. The only problem is nothing happened. I waited over 10 minutes and the bar never moved. Is there a step i'm missing here?  I have the original droid running 2. 2.

Unwanted Data Upload

Since i got my nexus one in the middle of january, i notice that once a month (on the 5-6th) my phone upload between 30-50 mb in a day. The rest of the month i have around 1 mb/day of upload. Since i have data plan with 250 mb included, 30-50 mb is quite a lot.

I strongly suspect the new auto-backup feature to upload my data to google. How can i disable it? I didn't found anything in settings. How does this auto-backup feature work? Do you guys also notice some unwanted data upload once a month?

Flickr Upload Tool That Supports Gallery Root Screen

I'm after a flickr upload app. I'm aware there are loads but i need a specific thing that no one appears to do. When you go to the gallery screen and you see the piles of photos on that first screen, you can press them and select piles. You can also choose select all to select all piles. If you then click share, none of the custom file uploaders appear, only the inbuilt ones (picasa, google mail, etc). I'm after a flickr app that will hook in to that menu though i'm assuming that there is a reason that none of them can.

Upload Photo Picasa Album List Blank On Samsung Galaxy Nexus

I just noticed this recently when trying to upload a picture from the gallery to picasa - the folder list is blank, clicking it or the new folder button does nothing. I've used it in the past so i'm not sure what changed - also working fine on my t prime, and, all of the folders are visible in the gallery itself, just not the upload screen. What i've tried so far that hasn't worked:

1) rebooting phone
2) disabling then enabling photo syncing in accounts and sync
3) clearing gallery and media storage data
4) multiple combinations of the items listed above

Anyone else have this issue? Or know how to fix it? ( I'm running stock ics ).

Is There A Way To Request Permissions From A User As You Need Them

I suspect there has to be. I mean i saw for bluetooth there is. I was wondering why it is not as easy for the other permissions. I mean heck we can intercept urls without even asking a user for the most part, so i would have to suspect that permissions have to have this ability.

User Experience And Ui Refinements

I think android has a ton of functionalities and that's definitely wonderful. I am not trying to be overally critical since i know the android team has been working hard and this is highly appreciated. However in all systems, there are rooms for improvement and here are a few areas where i think android can improve upon:

1) ui refinements - currently it's actually pretty hard to create good- looking ui in android. This is one of the main reasons why uis in android look like childplay compared to iphone apps. Any of the base/ core ui components in android (to be blunt) are not that pretty. To customize and add in the appropriate gradient and create the kind of sophisticated uis that are comparable to iphone apps is twice as hard. Having done development in both, this is something android should target. Overall the android ui is too blocky, too funky, and not stylish. And in some cases, they are moving backwards. The new tabs in android 2. 0 look worse than android 1. 6. The new spinner is also not doing justice either. A focus in this area will be helpful in order to create better ui for android applications.

2) user experience - instead of constantly just adding new functionalities, focus on user experience. For example, always having to click the menu key to bring up a menu requires additional clicks that are not necessary. Having to click a back key and guess where the current application ui will take me back to is also not great. Possibly provide a built-in on-screen menu in the framework? Provide a breadcrumb component as part of the framework as well?
