I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

View 1 Replies View RelatedI have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.
On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.
Of course it has something to do with the density but not sure how should I resolve this.
This is my code...
if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.
Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.

I searched the Incredible forums and sub forums and could not find an answer to this question, though I am sure it has been asked: If I want to go from my stock 2 GB card to a new card, and I want to preserve data AND have all apps still be able to read whatever data they were reading off the card, do I just transfer the files from one card to the other? I bet the only thing I need to make sure of is that new card is formatted with the same file system as the original card, right? I know copying data from one card to the other will preserve data, but I want to make sure I have no problems with apps, either, after inserting the newer card.
View 7 Replies View RelatedI have to create an app that draws a map reading data from a text file : for example the text file can be like
. index x y orientation
vertex 1 0 0 0
vertex 2 5 0 0.5
vertex 3 10 2 0.3
so i need to do in java something like fscanf does in c (fscanf scans the text file for known formatted data... example, in the file i written i know each line has a string float float float and i need to put them into a specific data structure that can be a list of elements "vertex"
next, when i have all the data, draw a simple image rappresenting the data..
my questions are...
there is a function like fscanf?
and then.. what's better for drawing the 2d map? i have tu use Opengl? At the end i have to draw the image pixel by pixel.. i hope there is something easier then openGL
I am trying to reverse engineer an existing android app and understand how a particular UI is constructed. I've found that I can rename the apk to zip and view some of the compiled source. The res/layout directory is populated with all the xml files that define the UI, but while they do have the xml extension, they are not in XML format. Is there anyway to convert these files back to text based markup?
View 2 Replies View RelatedI am currently working on a group project to build an Android game. I have been delegated the task of building a PC based level editor (which is all done). All I have to do now is decide on the file format for the map that is outputted. At the moment it is just a standard text file with different numbers to represent different tiles; E.G 0=path 1=wall 2=enemy.
1 1 1 1 1 1 1 1
1 0 0 0 2 0 0 1
1 1 1 1 1 1 1 1
The actual Android game then takes this file and stores the values into a 2D Array. However those who are making the actual game are having difficulty opening a text file, and others have told me it has to be done using an XML file. I have now been asked to find a away to take in this input. how I would read the text file and put the values into a int array[][] ? Or if it is easier, use an XML file and tell me how to format that file and read the values into a int array[][]
I have an app that runs perfect on 2.2 and 2.2 but always getting VerifyError on 1.6 while startup, I don't think that my app cannot run under 1.6 because I don't call any APIs that don't support 1.6. I'm really confused, does anybody has the same issue?

CODE:...........
I got an error message from a user that runs Android 1.5. The error reported os a java.lang.VerifyError and it seems to be based on the method setBuildInZoomControls missing. The thing is that this method should be there on an Android 1.5 device and my app's manifest specifies the minimum sdk level as "3".
<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"></uses-sdk>
The documentation for that method says that it is available on level 3: http://developer.android.com/reference/android/webkit/WebSettings.htm...)
So why do I get this error message?

I'm getting this error: "Uncaught handler: thread main exiting due to uncaught exception java.lang.VerifyError" It's only happening on 1.6. Android 2.0 and up doesn't have any problems, but that's the main point of all. Can't catch the Error/Exception (VerifyError), and I know it's being caused by calling isInitialStickyBroadcast() which is not available in SDK 4, that's why it's wrapped in the SDK check. I just need this BroadcastReceiver to work on 2.0+ and not break in 1.6, it's an app in the market, the UNDOCK feature is needed for users on 2.0+ but obviously not in 1.6 but there is a fairly amount of users still on 1.6.
private BroadcastReceiver mUndockedReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
//FROM ECLAIR FORWARD, BEFORE DONUT THIS INTENT WAS NOT IMPLEMENTED
if (Build.VERSION.SDK_INT >= 5)
{
if (!isInitialStickyBroadcast()) {
int dockState = intent.getExtras().getInt("android.intent.extra.DOCK_STATE", 1);
if (dockState == 0)

finish();

I'm trying to write a simple web service client app for Android, and I'd like to use commons-digester to convert the service's XML responses into objects I can work with. However, I'm getting a VerifyError as soon as I try to invoke any Digester method.
I've set up my dependencies (external jars) using Maven (the Masa Android plugin for Maven, and the Maven Plugin for Eclipse). The Masa plugin seems a little bit bleeding edge, so that may somehow be the source of the problem, but I can't be sure.
How can I debug this issue further, and what, if anything, can I do to resolve it? Is it not possible to use a library as simple as Digester on the Android platform?

I've got an application that uses overridePendingTransition to do some custom animations upon transitioning from one activity to the other. This was made available in Android 2.0, but I want to make the application work on Android 1.6. I figured if I just checked that android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.DONUT, and if not, don't do the overridePendingTransition.
However, I get a VerifyError, which I assume is caused by this: VFY: Unable to resolve virtual method 346: ../../Login: overridePendingTransition (II)V
Is it not possible to use newer functionality conditionally based on the SDK version?

View 3 Replies View RelatedI'm working on an android application for the analysis of measurements (e.g, blood pressure) using a Bayesian network model (PEModelOR is the class in my android application), which is embedded in a smart phone. Since the measurements are to be taken at sequential times, the model contains a number of variables referring to different time controls. With the initial version with 2 controls the model run without a problem but when I extended the model to 4 controls it crashed producing the following error:
CODE:.......
I saw that in a recent discussion http://groups.google.com/group/android-developers/browse_thread/threa... Dirk has encountered the same problem but unfortunately I could not see any solution to that. The extended PEModelOR method runs without problems in Java but it fails in the android application due to the dalvikvm verifier as far as I understood. The PEModelOR method is a description of a Bayesian Network in java and it simply contains definition of 62 variables and 62 probability distribution tables (in total 700 lines and the java file is 41 KB); below is a sample of the code (note that BayesNet is a class loaded via external jar):
CODE:......
Does the size/definition of PEModelOR cause the problem? I'm not sure how I can split it as it needs to be loaded at once for creating the network and running the model with available measurements. The thing is that this is even not the final version of the model, where the goal is to have 11 time controls, ending up with 112 variables and probability tables, and 1245 lines.
Is there a way out or alternative of implementing PEModelOR so that it does not fail at verification?
