[Q] Changing smali using apktool gives problem with r.Java

I've been stuck for a while now, trying to add some new functionality (day counter) to an existing apk (widget).
What I've done so far:
- unpacked the apk using apktool (using apktool d -d)
- start new project in netbeans with the specific source
- adding the java class to the existing package
The java code introduces some new parameters. I've added the parameters to different xml's. When I try to rebuild I keep getting the message:
cannot find symbol
symbol : variable layout
location: class fr.gdi.android.news.R
remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
Can anyone give me a hint what to do?

some additional info. This is the class I'm trying to add:
Code:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package fr.gdi.android.news;
/**

import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.Timer;
import java.util.TimerTask;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.widget.RemoteViews;
public class CountDays extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
Timer timer = new Timer();
timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager), 1, 60000);
}
private class MyTime extends TimerTask {
RemoteViews remoteViews;
AppWidgetManager appWidgetManager;
ComponentName thisWidget;
public MyTime(Context context, AppWidgetManager appWidgetManager) {
this.appWidgetManager = appWidgetManager;
remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
thisWidget = new ComponentName(context, CountDays.class);
}
@Override
public void run() {
Date date1 = new Date();
Calendar calendar = new GregorianCalendar(2010, 11,25);
long days = (((calendar.getTimeInMillis()- date1.getTime())/1000))/86400;
remoteViews.setTextViewText(R.id.days,""+ days);
appWidgetManager.updateAppWidget(thisWidget, remoteViews);
}
}
}

1. Apktool does not support writing your code in Java right now. Whole story is here: http://code.google.com/p/android-apktool/issues/detail?id=88 . If you want to use Java, it's possible, but you will have to use a workaround. It's not that hard to implement, but requires you to understand, how Java/javac/bytecode works. Workaround is described in above link, if you don't want to read full story, instructions start at "My script is here".
2. I think (but maybe I'm wrong) that you misunderstand, how R references work. These R.drawables.xxx strings aren't magically converted to resIDs at compile or run time. To use them you have to generate proper R class using SDK. If you use Eclipse or Netbeans, you don't have to do that, cause IDE regenerates R.java file each time you modify something in resources, so you can use R references in your code whenever you want.
In app decoded by apktool you have to manage resIDs manually. It's caused by the fact, that if you want to use some resources in smali, you can't let SDK generate ids for these resources automatically, cause resIDs are stored in smali in numerical form, i.e. "const v0, 0x7f012345", not something like "const v0, R.drawables.xxx". So if you would add e.g. "const v0, 0x7f012345" line to smali and resIDs would be regenerated, your line might reference other resource, that you want.
Of course that's not the case if you want to use resources from Java code, but as I said, this feature isn't fully supported by apktool. Also I think it would be good to add possibility to generate resIDs automatically, even for smali code, cause managing resIDs manually is very inconvenient. But that's future.
For now if you want to add new resource and use it from your Java/smali code, you have to modify public.xml file, add that resource with next free resID and then use that resID from your code.
If you want to know more, you could read this: http://forum.xda-developers.com/showthread.php?p=7380557#post7380557

@Brut.all: Thanks for your extensive answer! I will read the stuff you mention and get back at it.

@Brut.all: I think you're right about me not understanding R.java completely. But what I understand from your story is this. When I want a new resource to use in a new class and to be used in the existing xml, I would have to do the following:
- add a line to the res/values/ids.xml, for example:
Code:
<item type="id" name="main">false</item>
- add a line to the res/values/public.xml, for example:
Code:
<public type="id" name="main" id="0x7f0a0034" />
- add a line to the R$id.java and R$layout.java (don't exactly know which one)
Code:
.field public static final main:I = 0x7f0a0034
first: is this correct? second: How can I refer to the newly added resource in my new class. R.layout.main doesn't work, R$layout.main doesn't work.
Code:
remoteViews = new RemoteViews(context.getPackageName(), R$layout.main);

You don't have to do that. If you add new drawable, XML or @+id/something value, then it's ok.

<public type="id" name="main" id="0x7f0a0034" />

Yes.

No ;-)
If you want to use these resources in smali, then you could use them as is, e.g.: "const v0, 0x7f0a0034".
If you want to use my workaround to work in Java, then you could do the same, as above, e.g.:
Code:
int id = 0x7f0a0034;
or you could do this cleaner and generate R class manually: remove all existing R*.java classes (they aren't used) and create single R.java file:
Code:
public final class R {
public static final class id {
public static final int main = 0x7f0a0034;
}
}
and then you could use it as "R.id.main" in your code.
But first you have to implement workaround to use any Java code.

@Brut.all: thanks again for your reply. I think I didn't understand your previous story fully. I am 'developing' on windows, so your workaround is going to be tricky. Do you know if anyone has ported your script to windows?

Some additional info: I don't want to use a new resource in the existing smali code. What I want is a new resource, say @id/main, to be used in the xml files and in a java class, which describes the method that should be invoked when the widget updates.
What I've done now is that I've made a new R$main class with the resources I want to use. I also made the java class with the method and it refers to the resources mentioned in the R$main class. This way I can build it without problems in Netbeans. But when I want to use apktool, I keep getting the message:
Code:
I: Checking whether sources has changed...
I: Smaling...

Maybe I'm completely on the wrong track...

Sometimes I get NullPointerException instead of real smali errors, when I'm doing "apktool b". I think it's a bug in the apktool. Try to smali "smali" dir normally, without apktool to see errors.
But I don't really see much sense in adding any Java classes, because they just can't work without additional steps. What my script does, is:
javac all files from brut.iface
javac all files from brut.src against compiled brut.iface
convert compiled brut.src to smali. This is done in two steps:
dx them to classes.dex
baksmali them using baksmali or apktool
Most of commands from my script (javac, dx, apktool/baksmali) should work on a Windows. File operations, i.e. mkdir, rm, cp should be easily portable. I don't know, how to replace "find" command.
You could try to use Cygwin - then you should be able to run my script on a Windows.

To do this properly, I'm installing Linux now, so my next reply could take a while...

Thanks, could you plz upload the full source code ?
Does it support images and clickable feed so that clicking any feed directs the user to the website ?

I will upload the full source of my app today.
It will read any section of the xml so if there are images you will be able to extract the URL and use it in your app. It does support clickable feed also, just by extracting the post URL again.
The app I made is for an audio podcast.

Here you go... hope it helps

hello tony,
first thank you for the source code.
I tried running your source code but I am getting these error messages:

Sorry, I must have left that in from when I was playing with Fragments, it's not needed. You can remove it from the build path. Right click the project, properties, then find and remove from build path.

I would deeply appreciate if you could upload a fresh copy of source code without this fragment file / issue.
thank you

OK. I'll upload again tomorrow.

thanks i will keep an eye on your site and here

I have re-uploaded the source, now without the Fragment compatability.

I tested the code and I think it only works for the RSS FEED that you added in the code.
I tried other rss feed like "http://rss.news.yahoo.com/rss/mostviewed" mentioned on your website (in comments) and few other rss feeds but nothing seems to be working.
(thanks once for all the help)

I wouldn't worry about those warnings.
The app I have uploaded is specifically for the Epileptic Gibbon Podcast, which is a wordpress site.
The code should just need slight changes to match the rss feed you want to use. I suggest you download the rss xml for Epileptic Gibbon and the rss xml for Yahoo and compare the differences.

really great code.
Thanks.

I could really use some help.
I would like to use this app to pull feeds for this site.

But have no idea how to add this to eclipse and then turn it in to an app.
Could someone help out with the steps to take?
Thank.

[Q] Write to file (not sdcard)

How can you write to a file that is not in the sdcard, it's a highscore text file that I just want my int "clicked" to go in there.
(Lol yeah.)

I doubt you can write text into a file that is NOT in the sdcard, unless you have root permission. However, you can store those highscores etc in a SQLite Database or SharedPreferences.

Okey, thanks! Then how would I be able to write to SharedPreferences (as it seems it is much easier than SQLiteDatabase?)
I read the site but couldn't manage it.

Create a SharedPreferences.Editor object and use its put... methods with a tag for your int. Then call apply() or commit() and retrieve the value later with a PreferenceManager (setDefaultValues(this, R.xml.whatever, false) and getDefaultSharedPreferences (this) ... ). It's the usual way to get preferences, same as if you saved them in a PreferenceActivity.

You CAN create a text file on the /data directory without root permissions!
However, this can be done just in the directory of your app. Check this tutorial: http://developer.android.com/training/basics/data-storage/files.html#WriteInternalStorage
It IS possible!

For SharedPreferences:
Instantiate a new SharedPreferences:
Code:
SharedPreferences prefs = this.getSharedPreferences("com.example.app", Context.MODE_PRIVATE);
To edit a value:
Code:
prefs.edit().putString("highscore", "12345").commit();
where "putString" can be "putInt", "putLong" and "highscore" can be any words you want.
To read the value:
Code:
String highscore = prefs.getString("highscore, "0");
where "highscore" must be the same value a the one when you're editing, and 0 is the default value if there is no value stored previously.
To save a file like what Nikwen said:
http://stackoverflow.com/questions/13161470/saving-file-in-internal-storage-android
----------------
However in my opinion, I think SharedPreference is easier as everything is handled by the OS itself, without you needing to read the file line by line, parse the data and get what you need.

how can we access the committed data from another class?

You can only get access to the SharedPreferences from an activity or a class with an activity context like a dialog with getActivity(). Then use the SharedPreferences prefs = this.getSharedPreferences("com.whatever",...)

What means with "com.example.app"? Is that just my package? And where should the file be placed in eclipse before running?
If I got like a number that is changing each time I click a button, and then I timer that counts from 60 down to 0, when it's on 0 I have onFinish method, what should I put there to make the text inside highscore.txt file to edit to what my int is (clicked)?
It's hard to explain.. :/
Edit:
I have this code:
Code:
SharedPreferences prefs = getSharedPreferences("com.SAH.clickr", Context.MODE_PRIVATE);
String highscore = prefs.getString("highscore", "0");
final TextView text2 = (TextView) findViewById(R.id.highscore);
text2.setText("Highscore: " + highscore);
When running it has to force close upon start (this code is in the onCreate method).
I get this error in the logcat:

Your shared preferences object is null I guess try SharedPreferences prefs = PreferenceManager.getDefaultSharedPreference(this) ;
I suggest use a sqlite database for highscore shared preferences can easily be tampred

To avoid Sql and
To prevent tampering of highscore data try simple encoding like representing 1 by 'a' in the shared preference value or something else of that kind

Forget everything below, I fixed it, I just put "inputStream.read()" instead of inputStream in "if(inputStream > clicked)"
Thx everyone.
Now, it just says that I didn't beat my highscore even if it is a 0 inside the text file.. :/
!!OLD BELOW!!
Okey so here's the code that should work, the only thing that is not working is that I want it to write to the file ONLY if the int "clicked" value is higher than the value inside the file.
Code:
Code:
String filename = "highscore.txt";
FileOutputStream outputStream;
FileInputStream inputStream;
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
inputStream = openFileInput(filename);
if(inputStream > clicked){
outputStream.write(clicked);
outputStream.close();
}
}catch (Exception e) {
e.printStackTrace();
}

You cannot compare ints and InputStreams.
You need to read the value from the file as a String using a BufferedReader and then get it as an int using Integer.parseInt().
Then you can compare the values.

It looks to me like you don't have all of the required toolchain installed. Take a look at the link below down the page where it says "Requirements for Linux" and lists all of the packages you need to have. I don't know how BBQLinux works so you'll have to translate what it does for Ubuntu-Fedora-Arch into whatever package manager you're using.
