I am writing an application that will run on 2.0 and above. Now, I am thinking of adding the Data backup feature to the application. Is there anyway to modify the manifest file to include the metadata only if the phone is using Froyo(2.2). Ideally, i would like to avoid creating a separate application for just Froyo.

1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...
So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI?
Hard to explain...
Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want.
Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that?
In an Android application I am writing, the styling for my various TextView elements is defined in an xml resource. I would like enable the user to change certain styles such as android:typeface using a PreferenceActivity. Is there a way to modify a style resource programmatically such that all associated widgets will update correctly? If not, must I manually select all widgets by id and change their styling?
View 1 Replies View RelatedHave a question regarding RotateAnimation. If I do not set the property FillAfter to true then the image in my view, that I use RotateAnimation to animate, returns to the initial position after the animation is done. My problem is that when I set fillafter to true when I later set the image on my imageview to another image than the one I animated some kind of transformation is applied to that image also.

I am looking for some answers from some of the experts here. I have a project in mind that I want to start. It is about using HTC's Touch HD phone as a device in a museum with rich media/video about the art and the artists on it. Besides the videos and animation, I also want to show some content from a web browser. Now my biggestest issue. I do not want that the museum guest who pick up the phone for the tour get to see the standard Android user interface. Is there a way to develop a new user interface that would start up directly once the phone is turned on? It should then automatically start the app with the museum infos. Later I may want to add some GPS functions and even sms and photo taking, etc....

View 4 Replies View RelatedI am trying to add permissions to my application manifest, so it can access other apps that the user installs at runtime. I thought the way to do this was to define a permission-tree in the manifest, and then use PackageManager.addPermission() to add permissions under that tree. However, I can't get this to work and the documentation I found wasn't conclusive. Could anybody show me how to do this by means of a simple example?
View 3 Replies View RelatedI'm primarily working on the Android SDK on windows, but would like to modify/tweak some functionality in the application framework.I have a separate ubuntu box where I downloaded the android source code, built it using "make" as well as "make sdk". I have a few questions in mind. Is it possible to import the binaries that I built on the ubuntu box into the android windows SDK? If so, what are the (proper) steps in doing so.For example, say I modified some functionality in the Activity.java file, then built it on ubuntu. I want to be able to make use of my modifications and continue my app development on my Windows SDK. Can I somehow import the framework binaries built from this step over to my windows SDK and continue my development from there? If so, what are the binaries I need and what are the steps to import them?

View 2 Replies View RelatedThis question actually has two parts.
The first part:
I've been developing my first app for a couple of weeks now. I have 5 screens and everything seems well. However, I'm considering changing the app's navigation to a TabView.
I haven't delved much into it, but I'm hoping someone can save me a little bit of time. It seems that people don't generally place Activities inside each tab. They simply point the tab content to a View. This is where my major setbacks are. 1) I already have Activity classes full of code and 2) I can't quickly guess how the structure of an app using TabView looks. For example, where do I put the handler code for clicking a button on a View? Does it all just get dumped into the TabView Activity somehow?
What I would like is if you could please give me a quick synopsis of what I'm looking at doing, answers to any questions you think I may have, and point me toward some resources for creating TabView applications. A quick Google search really just shows me how to create a TabView Activity and add a couple tabs to it. The code doesn't go any deeper. For example, say I have a layout xml to show in one of my tab's content pane, where does the code go for clicking a button I have in that layout?
The second part:
I've added a TabActivity to wrap the Activities I currently have in. At the moment I have Activities populating the content of my tabs (though ultimately I'd like to do this in the most efficient fashion, which doesn't seem to be having Activities be tab content). I've noticed something rather annoying. My MAIN Activity is an Activity I wrote for my user to log in to their account. After logging in, they are taken to my Tab Activity. Here is what happens:
When I am on my Tab Activity and I "minimize" the app by clicking the Home button and then launch it again, I don't get taken back to the Tab Activity. I get taken to my log in Activity. Why? I don't have the launchMode of my Tab Activity set to singleInstance... or is it singleInstance by default? How can I make the app re-launch showing the Tab Activity (ideally by setting some parameter, assuming I'm doing something wrong, and not having to save this data off somewhere and reading it and programmatically telling it what to go to)?
I have a ListView, displaying some items, containing an ImageView filled with a standard image at first and a line of text.
What I wanna do is downloading one thumb after another with an AsyncTask and step for step change the standard image with the downloaded one. How to realise this?
The ListView contents are managed by an enhanced ArrayAdapter.
So, I added the receiver (contained in application) in the manifest. Broadcast doesn't fire my broadcast receive.
<receiver android:name="mypkg.IncomingCallReceiver">
<intent-filter>
<action android:name="android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED"/ >
</intent-filter>
I have two applications A and B (in different packages). A can send an explicit intent to B to perform some kind of action. Then,I enforced a permission in application B called "my.permissions.B_PERMISSION ". The A application can still call B despite the fact that it doesn't have the appropriate <uses-permission> in its manifest. Have I understood something wrong?

I see that multiple broadcasts (ACTION_TIME_TICK, for example) cannot be registered in the manifest, the must be explicitly registered via Context.registerReceiver().

I am essentially attempting to create a Receiver that is awakened as soon as possible after my application is installed. The first time it is awakened, it registers a few listeners, and then it unregisters itself so it is never called again. (I really wish there was an intent fired immediately after your app had been installed, to allow a small bit of setup.
