Android :: R File Stopped Generating / How To Fix?
Dec 8, 2009
Suddenly my R file has stopped generating. It has deleted itself and won't come back. In eclipse, I have all the latest updates to the sdk and the plugging. Has this ever happened to anyone else before, how do you fix it?! I have tried restarting, cleaning the project, rebuilding, doing the Android->fix project properties.
After i created my project. The R file is not generating. I need to build the application to create that R file. After i add any image or string. It is not automatically adding in R file. I need to build another time to generate that code in R file. what is the reason?
I generated a new android project in eclipse. I then copied all the files from chapter 3 in my book over to the project. After doing so the R.anything is not available and the resource file is missing. I try to clean the project and generate it but it isn't working. What I can do to fix this error?
I am trying to publish my first Android application, and therefore need to sign the app with a keystore. At first everything goes well. I type the following into the command prompt: keytool -genkey -v -keystore testKeystore.keystore -alias testKeystore -keyalg RSA -validity 10000. I answer the several questions that follow, but after the last question, I get the following error. keytool error: java.io.FileNotFoundException: testKeystore.keystore [Access is denied] Maybe I am doing some silly mistake, but I have followed several guides on the internet on how to make a keystore, and I thought that was all there was to it?
I'm trying to generate the MD5 Fingerprint I will use with the release of my application. I used Eclipse to Compile and Sign my application, which gave me a keystore file and a .apk file. Now i need to generate the MD5 for my MapViews. I tried using the cmd prompt to generate it, but everytime it states that no such file exists. Is there somewhere special i need to be storing the keystore so the keytool has access to it? Also, once i get the MD5 fingerprint, all i have to do is insert it and re-compile and sign my application (the same way i previously did it). Am i correct on that assumption? I've read through the developer docs and I'm still unclear on the whole process.
I installed the bluetooth file transfer app from the market and it worked fine for a couple of goes, then my 6 yr old got hold of my phone and i am not sure if he altered some sort of setting and it is now not sending out files (it says on the recieving phone, - connection dropped- ) it is also now not connecting to other phones.
I renamed the package in the manifest from com.a to com.a.beta in order to upload a different version to the Android Market.
In the manifest I changed the referenced entities (services, activities etc.) to use the fully qualified name "com.a.X" instead of just ".X". Of course the code still references com.a.R, so there is lots of errors in Eclipse. My expectation would have been though that R.java will be regenerated in com.a.beta. But it is not generated at all.
I am trying to add some updates to an already released application but something has happened with my workspace that prevents me from Running or Exporting the application. I keep getting the following code...
You think it would be an easy fix but I looked into the HDPI drawables folder and there were no doubles. I even went as far as to delete the entire folder and the error still appears. Anyone got any clever ideas?
I would like to be able to generate unique serial numbers for each Android device for use in unlocking an application. How could I do this? EDIT: The reason is I want to revamp a paid application and provide users who have paid for the old version, which will have a different package name, a way to obtain the full version by downloading an unlikable free version of the application. I would push an update to the old version that would generate and display the code that they could enter to turn the Free version into a fully functional version.
I'm working on an Android class that extends MapActivity. I have set the OnTouchListener and everything works okay for the first MotionEvent. After the first MotionEvent, the system stops either generating MotionEvents or receiving them or both.
Does anybody know what I have to do to keep receiving MotionEvents?
1. How do you programmatically generate key strokes? I found some tutorials where it says to use IWindowManager, but that doesn't exist anymore in 1.5. (And WindowManager doesn't provide any function to generate key strokes)
2. How do you programmatically select one item from a ListView? Is it possible to do it with the index of the list item (it's position in the list)
I put two projects into Eclipse, called Project1 and Project2.Project1 is independent, but Project2 must be dependent to Project1.When I build the Project2, the error msg comes like this: Error generating final archive: duplicate entry: AndroidManifest.xml
I'm creating a 2d game and have run into another problem. I use array lists for generating everything that has multiple instances, background images, foreground images, enemies, etc. The problem I have is if I choose to generate any more than a certain number of any given object I get an arrayindexoutofboundsexception even though the code works fine with lower numbers. For the background images that are larger, the number seems to be lower (about 40). for enemies, which are smaller, the limit is more (about 150). I don't believe I'm out of memory as I'm not getting that error.
generation code Y=0 last = 13
The above codes work if the variable is lower. But sends the error as soon as it goes above a certain number.
I was just wondering, theres a lot of people who sell unlock codes for htc. But they must get them from somewhere, somehow. were living in 21st century and everything can be hacked / cracked, so is there a tool similar to a KeyGen which can generate unlock codes for htc? I think there must be one somewhere.

This question has been asked(and answered) many times about dynamically generating and loading java bytecodes at runtime into a running Dalvik VM, but is there any way to load dex files/bytecodes into an app at runtime?
Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?
I am successful in creating file using openFileOutput(). and can read the file using openFileInput().
I am able attach file from external storage sdcard while emailing the same using getExternalStorageDirectory as sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+Environment.getExternalStorageDirectory()+"/ zibra.txt"));
But while trying to attach file from the openOutputFile stored area using sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+ getFilesDir() + "/zibra.txt"));, resulting emptied file emailing.
My file is stored in "/data/data/com.example/files/zibra.txt".
I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format: 1|a|This is line 1a 1|b|This is line 1b 2|a|This is line 2a 2|b|This is line 2b 2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line. b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value <!--sample XML --> <data> <line number="1"> <entry name="a">This is line 1 a</entry> </line> </data> c.) Should I just copy & paste the whole file as a static string array in the application and use that. [EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".
I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.
I have created the private signed keystore file using eclipse and i have released the apk files in android market website. after some days we got some issues from users and we have fixed the issues but i don't have private signed keystore file. while making the apk file i need to use previous version release used private signed keystore file. Is there way to get private signed keystore file from previous apk release file?
How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.
I'm developing with Android 2.1 on a Nexus One with firmware 2.1 update 1. I'm using the RehearsalAudioRecorder class from here: http://rehearsalassist.svn.sourceforge.net/viewvc/rehearsalassist/ Code...
I'm writing a bitmap editor. Each document consists of about 3 bitmap layers and documents are, at the moment, saved as a custom file with a .bme extension. These files can be converted to standard jpg/png files by rendering each bitmap on top of one bitmap and saving the latter. I need some way for the user to be able to select .bme files they've created already. Is there anything in Android that can make this easier for me? The only option I can see is to write an activity that creates a list view and write a list adapter that looks for .bme files on disk i.e. a copy of the standard "Media Gallery" app that works for my .bme files. The list adapter will either have to generate a thumbnail preview of the image to show to the user or I'll have to package such a preview in the .bme file when they're created. This is the only option I can think of. I thought I'd ask in case there is more Android friendly way of doing this. For example, can you add custom file support to the "Media Gallery" app?
