[android-developers] viewport meta tag AndroidTV width/height attribute not working
I've set up an Android TV app using a Webview object and followed the explicit directions as to getting the meta tag's width/height defined (so that they are used when rendering the app). No matter what I do to alter the attributes of the meta tag, they do nothing to change the width and height: Width:912 Height:516 Device Pixel Ratio: 2 I've tried several things like setting various Websetting methods, but no luck. Anyone out there experienced this issue and come up with a resolution? webSettings.setJavaScriptEnabled(true); webSettings.setMixedContentMode(webSettings.MIXED_CONTENT_ALWAYS_ALLOW);//Allow mixed content webSettings.setLoadWithOverviewMode(true); webSettings.setUseWideViewPort(true);//Sets whether the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport webSettings.setMediaPlaybackRequiresUserGesture(false); webSettings.setDomStorageEnabled(true); webSettings.setDatabaseEnabled(true); webSettings.setJavaScriptCanOpenWindowsAutomatically(true); webSettings.setBuiltInZoomControls(true); webSettings.setSupportZoom(true); Here's the meta viewport tag -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Spinner items missing selection radio button
Hey, i asked it at SO few days ago, no answer yet, hoped someone here will have an idea... (http://stackoverflow.com/questions/6146442/spinner-items-selection- radio-missing) When my items contains English and/or numeric signs, it shows the radio selection near the item, but when it doesn't contains any English and/or numeric signs (contains only Hebrew in my example) it does not show the radio selection near the item. For the adapters (array adapter) creation i used the layout android.R.layout.simple_spinner_item And before setting the Spinner adapter I did adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); The solution I found for now, is set the layout to simple_dropdown_item_1line; this solves the problem by not showing the radio button. Any ideas on how to get the radio button visible always? - correction - it does not solve the problem, in _few_ of my spinner the text is now whit (on a white background..)

I don't understand the underlying protocol horribly well, but you need to actually scan for the uuid using SDP, which requires a call to the API. When the device is in range, I am able to call BluetoothAdapter.getRemoteDevice and retrieve the friendly name. But when I am not in range, it seems this information is cached. I was thinking if I can use the friendly name as an indicator whether the device is within range (i.e If friendly name is not null, then it's in range). I am certain there is better way to do this. But it seems the only way is to establishing a connection. I don't think there is a better way, at least with the current API. Unless by better way you mean a more elaborate synchronization mechanism or something like that. But yes, I think at least from the API exposed by the android system, you have to do polling.

[android-developers] Mounting and UnMounting SDCard
Hey, After some searches (actually a lot :)) the only related solution i found is to take the MountListener, MountService and their friends (some other related class) and to add them to the project. but when the code reaches to listenToSocket() function, it crashes on socket.connect(address); (line 203) the reason is permission denied. the apk contains the internet permission (which is the only somehow related permission since we create a LocalSocket). I also added a FactoryTest (app will run as root by manual) permission. non of them helped. from digging some more up, i saw that it connects to the VOLD (volume demon) and send commands to him. i checked to see if VDC is exists (thought it might by 2.3 breaking change or something like that...) but its there. the only thing i can think of is that i messed something up in the Mount* files and I should call those functions via reflection but i don't see how it will help me since it's crashing on permission denied. any ideas? if anyone ever done it (or know what to do) It will help me a lot to hear how and what I can do.

[android-developers] Configuring automated build scripts
I have an app that needs to be built in 3 versions, where the only differences between the versions are a few strings that need to be compiled with the app. One of those strings is the IP address of a server where the app needs to send data to, so for security reasons I want this to be compiled with the app rather than be a config file that's loaded in runtime. I want to set up a build script that would do the following: 1) Build my the 3 versions of the apk, based on some param file for each version, which would state the string values that should be compiled into it. I am imagining that this would be implemented by having the Android source code import a specific strings file, and the build script would replace that file for each version before compiling it. 2) Also generate some server-side .php files that depend on information from the build (e.g. the php file should have the latest version number of the Android app). 3) In the end will create 3 output directories one for each build, which have the respective .apk file and relevant .php files 4) Another note is that currently the app supports android 1.5 up to 2.1, and I read that sometimes build commands in Ant might be different between 1.5 and newer versions. 5) It would also be great if this mechanism could be generalizable to more than 3 apk versions in the future I don't know much about build scripting.

[android-developers] How to get a phone number in normalized form
I am looking for a way to get the normalized form of phone numbers (which is probably the format Android uses when comparing two numbers). There are a few mentions of the normalization process in the dev site and elsewhere, but I could not find a single example where its accessible. I looked at the PhoneNumbeUtils which seems to have some number formatting functions, but I saw on this forum that it was recommended not to use it and that it would be deprecated soon. Please let me know if you know how to access the normalized form. Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: intensive writing to internal memory
Indeed we are not able to push continuously to a server - both because of network availability and also the power consumption is probably much higher than saving it and sending in bulk. I think we will indeed aim for the 3 level approach and try to put as little as possilbe on the main memory just to be safe.. Thanks to everyone who answered! Nadav On Apr 4, 4:37 pm, Bob Kerns r...@acm.org wrote: If Jason's suggestion of pushing it to a server is inadequate, you can buffer events, and only write them out once a minute or 10 minutes or something. This will put an upper bound on the number of writes performed. You can combine the approaches, and push to the server, and only write to the filesystem if you don't succeed in pushing to the server within a decent interval. Then when communications is reestablished, push the saved data up first. You could also send it to the SD -- and when the SD is not available, buffer it on the local filesystem until it becomes available again. Essentially, we're looking at a 3-level buffering hierarchy -- RAM, local flash, and either SD or server. The more the buffering in RAM, the more data you risk losing in the event of a crash, but the fewer writes and less battery required.

[android-developers] intensive writing to internal memory

[android-developers] Re: Bluetooth API in 2.x problem.
I've also been quite frustrated by this issue since I'm also doing activities that depend on a device being always discoverable. There is an open issue on the Android project page about this - if you (and others) would like to see this implemented please star it! http://code.google.com/p/android/issues/detail?id=6348q=bluetooth%20discoverycolspec=ID%20Type%20Status%20Owner%20Summary%20Stars Moneytoo - what you say is interesting - do you mean that if my app has a specific service registered then it will respond to any peer requesting it even when it is not discoverable? However, even if it does work, from my prior experience working with BT, polling for specific services is much slower than doing regular BT discovery (and possibly more power consuming?)

[android-developers] Keeping notification at the status bar after the service that spawned stops
Hi, I have a main application, that at some point spawns a service that checks for updates, if it finds any, it posts a notification with the link to the update, and then the update service stops. Through the debugger I've noticed that the notification pops up but then disappears once my service is stopped, which I guess makes sense since the Notification object was instantiated within that service. What would be the best practice of keeping that notice available until the user clicks it? I can see two paths: 1) somehow attaching the notification to my top service - which might get really ugly -- since that update service is spawned by another sub-service that is spawned by a broadcast receiver... so even if i wanted to somehow pass the object of my top level service it would mess the entire abstraction of my app structure and would force me to keep pointers to it through every event and service that I use... Perhaps there is some other way to get that service through the app's context? or any other alternative? 2) Finding a way to keep my update-service alive until the user presses the notification, but I'm not sure if there is any intent broadcasted that I could listen to... Any suggestions would be appreciated, Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.
