[Q] Changing smali using apktool gives problem with r.Java - Android Software Development

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:
/*

package fr.gdi.android.news;

import java.util.Calendar;

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.

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...

Debugging a dll

I'm creating a project as a dll. Can anybody tell me how to go about debugging it. I attach it to the remote process "services.exe" but any breakpoints I put, dont hit and display an exclamation mark, saying that no executable code exists at that point..
How do you guys debug ur DLLs??
be sure that services.exe is the correct process
bye
Let me explain a bit. Actually I'm trying to write a WinMob service (This is my first time writing a service dll, infact, first time writing a dll).
I created a dll with the DLL_PROCESS_ATTACH case in the ul_reason_for_call calling a SPC_init function (exported using __declspec(dllexport)).
Moreover, I added these entries to the registry:
[HKEY_LOCAL_MACHINE\Services\ShantzABC]
"Order"=dword:00000009
"Index"=dword:00000000
"Prefix"="SPC"
"Keep"=dword:00000001
"Dll"="ShantzABC.dll"
"FriendlyName"="ShantzABC"
But the service didn't load. Then I added the line "services load ShantzABC" to the deployment options of my VS2005 project. Now, on pressing F5, the service loads (I know because I put a MessageBox() inside the SPC_init, which is now displayed on screen) BUT:
1. I can't see the ShantzABC.dll loaded in Remote Process Viewer tool (seeing for services.exe)
2. Moreover, I can't hit any breakpoints in my project, even the one kept on the MessageBox() line. (Though now they have stopped giving the error "not an executable line" that they were giving earlier)
Actually I'm trying to start a project which could benefit greatly if it was a service instead of me writing an exe for it..
So, any pointers??
EDIT: added a part of the code:
Code:
#include "stdafx.h"
#include "ShantzABC.h"
#include <windows.h>
#include <commctrl.h>
HINSTANCE g_hInst;
// This is an example of an exported function.
__declspec(dllexport) HRESULT SPC_init(void)
{
HRESULT result;
MessageBox(NULL, TEXT("initCtrl"), TEXT("INIT"), MB_OK);
result = S_OK;
return result;
}
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
HRESULT result;
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
//save instance handle
g_hInst = (HINSTANCE) hModule;
result = SPC_init();
MessageBox(NULL, TEXT("initCtrl"), TEXT("main"), MB_OK);
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
1. implements all the exported functions for service:
Init, Open, Close, Deinit, IOControl, Read, Seek, Write also if empty (just return 0)
2. instead to use F5 to debug it, try to deploy the dll and attach the process to debug it: Debug > Attach to process.... (vs2005's menu)
i hope this help you
Could you please direct me to an SW development environment, which documents the above functions, Reg_Key meanings etc. sort of a reference guide? What compilers/linkers do you guys use ?

I implemented all the functions and just returned 1. (didnt return 0 because read on a msdn blog that returning 0 form dllmain or xxx_Init will unload the dll)
But again on attaching to services.exe, its not loading my dll(or unloads it soon after loading). (Dll is kept in \windows)
So, cant find the dll in the modules window and so cant load the symbols for it in order to debug it..

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:
Code:
Description Resource Path Location Type
Project 'EppyGibbonPodcast' is missing required library: 'C:\Users\Tony.DZNT\AndroidDev\android-sdk-windows\extras\android\compatibility\v4\android-support-v4.jar' EppyGibbonPodcast Build path Build Path Problem
The project cannot be built until build path errors are resolved EppyGibbonPodcast Unknown Java Problem
Attribute minSdkVersion (4) is lower than the project target API level (10) AndroidManifest.xml /EppyGibbonPodcast line 1 Android ADT Problem
This is the version of my eclipse:
Code:
Eclipse IDE for Java Developers
Version: Helios Service Release 2
Build id: 20110218-0911
I am using 2.2 but I can see you created this code for 2.3. I do have API installed for 3.0 and 3.1 etc so I should be at-least able to run the program on virtual mobile (on PC thru eclipse) but getting the above error msgs.
Please Help.
I just found the file "android-support-v4.jar" in this location:
D:\Android\AndroidSDK\android-sdk-windows\extras\android\compatibility\v4
now how and where I can link this path ?

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.
Hi tony,
I did try to remove it and now I am getting these errors:

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.

Let me know if you have any problems, but this should run fine now.

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.

Interested in toggling a value in the build.prop

So in my toolkit, id like to design an activity where I could point it towards certain lines in the build.prop to allow a user to easily toggle, for instance this line
qemu.hw.mainkeys=0
So, in the layout xml, lets say it had "Enable Nav Bar" and a "Toggle Button" for on/off
Where would i start in developing such a feature?
You create a ToggleButton and whenever it is clicked, you change the line.
What is your problem?

My concerns are wouldnt I need to add ro permissions on the prop before toggling and a reboot action to apply
I think your device needs to be rooted to be able to write to the build.prop file. You do not need root access to read it though
I'm from mobile and i can't post some code but i will give you some hints
To edit build.prop programmatically first you ne ed to be rooted then you can use the shell command "sed" to exchange values. Take a look at AOKP settings source on github and look for density changer class
If you want to import various build properties you can use fileinputstream and read the file line by line then let the app create listview custom items for every line in the file (you need a custom adapter) .
Sorry if this post it's not really useful but i will edit this when at PC

I Wrote something up but I keep getting force closes "Not a java code monkey yet, still learning" and Ill post here what I have when I get to my pc later. Maybe you can see what Im missing or did wrong. What I did is I have a preference screen similiar to AOKP density changer class. What Im going for is a PreferenceList that you click and your values are Enable or Disabled and another preference to reboot to apply settings. Im wanting to allow the user to enable and disable the Navigation Bar by toggling it through the build.prop. If this works, I want to add more toggles custom values like change your phone model, Screen Density, build number, ect; but figured Id start with something simpler first and see if it works.

this is the method you need:
Code:
private void setLcdDensity(int newDensity) {
Helpers.getMount("rw");
new CMDProcessor().su.runWaitFor("busybox sed -i 's|ro.sf.lcd_density=.*|"
+ "ro.sf.lcd_density" + "=" + newDensity + "|' " + "/system/build.prop");
Helpers.getMount("ro");
}
( method took from here : https://github.com/TeamBAKED/packag...aked/romcontrol/fragments/DensityChanger.java )
newDensity is the int/string you let the user set ( you can use a seekbar or a dialog or what you prefer)
you have also CMDProcessor().su.runWaitFor : just use the classes you can find here : https://github.com/TeamBAKED/packag...11bca71808c9143/src/com/baked/romcontrol/util
just add these classes in your project ( these are to simplify your life when you need to use android terminal [ remember to give credits on your app! ] )
Now, you can use various types of views and methods to show to the user all the available props:
- manually add every view for every line in your build.prop ( this will probably limit the compatibility with other devices and make your app "laggy" due to "gazilions" views )
- use a blank linearLayout and inflate a "row view" for every line in build.prop:
read file line by line and import every line in an ArrayList:
Code:
ArrayList<String> Tokens = new ArrayList<String>();
try {
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("/system/build.prop");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
// Read File Line By Line
while ((strLine = br.readLine()) != null) {
strLine = strLine.trim();
if ((strLine.length()!=0)) {
String[] names = strLine.split("\\s+");
Tokens.add(names[0]);
}
}
for (String s : Tokens) {
//System.out.println(s);
//Log.d("NNNNNNNNNNNNNNNNNN", s);
}
// Close the input stream
in.close();
} catch (Exception e) {// Catch exception if any
System.err.println("Error: " + e.getMessage());
}
names = new String[Tokens.size()-1];
names = Tokens.toArray(names);
ArrayList<String> value = new ArrayList<String>();
try {
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
// Read File Line By Line
while ((strLine = br.readLine()) != null) {
strLine = strLine.trim();
if ((strLine.length()!=0)) {
String[] val = strLine.split("\\s+");
value.add(val[1]);
}
}
for (String s : value) {
//System.out.println(s);
//Log.d("NNNNNNNNNNNNNNNNNN", s);
}
// Close the input stream
in.close();
} catch (Exception e) {// Catch exception if any
System.err.println("Error: " + e.getMessage());
}
values = new String[value.size()-1];
values = value.toArray(values);
LineNumberReader lnr = null;
try {
lnr = new LineNumberReader(new FileReader(new File("/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table")));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
lnr.skip(Long.MAX_VALUE);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int num = lnr.getLineNumber();
Log.d("LINES", ""+num);
int i = 0;
//now inflate a specific view for every line
// you can also filter every item for example by reading the string and inflating a different layout using an if statement
for (String s : names) {
LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View v = inflater.inflate(R.layout.uvrow, null, true);
TextView text0 = (TextView) v.findViewById(R.id.text0);
ImageButton back0 = (ImageButton) v.findViewById(R.id.back0);
final EditText edit0 = (EditText) v.findViewById(R.id.edit0);
ImageButton fwd0 = (ImageButton) v.findViewById(R.id.fwd0);
text0.setText(s);
parentGroup.addView(v);
edit0.setText(values[i]);
/*
* if you need to set listeners and actions insert them inside this loop!
*/
}
if you need more informations, take a look at my code on github ( was my first "really useful" app ): https://github.com/cesco89/CustomSettings/blob/master/src/com/cesco/customsettings/UVTable.java

[Library] Cmd library: Execute Your Java Codes With Root Access Privileges

Synopsis:
Have you ever wanted as root apps developer to use your favourite Java codes instead of bash/shell commands?
Have you grown tired of Runtime.getRuntime.exec("su") and ProcessBuilder("su").start()?
I did and still do, that's why I've been searching for a solution for my problem until I found out in AOSP source code that some of *.java files run with root access, tracking the way they execute them with root access led me to make this simple library.
Description:
Cmd library -short for Command- is an open source (licensed under Apache licence V2) that allows you to execute java commands with root access privileges by passing package name, full class name and whether your app is a system app or not in just two lines of codes.
For instance, suppose you want to flash a *.img recovery image, the first thing comes to your mind is this code:
Code:
busybox dd if=/path/to/recovery.img of=/path/to/recoveryPartition
lets say /sdcard/recovery.img is the file path and /dev/block/mmcblk0p12 is the partition (Samsung GALAXY Ace Plus GT-S7500)
Here is how to implement it:
Code:
...
Proccess proc = Runtime.getRuntime().exec("su");
OutputStream stream = proc.getOutputStream();
stream.write("busybox dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p12".getBytes());
stream.flush();
...
Pretty simple isn't it, now suppose you don't know anything about bash codes, what will you do?
Let me answer this question:
1) Learn some bash.
2) Use Cmd library with java codes.
Here is the same implementaion with Cmd library:
Code:
...
JavaRoot root = JavaRoot.newInstance(getPackageName(), RootCommands.class.getName(), false);
root.execute("/sdcard/recovery.img", "/dev/block/mmcblk0p12")
...
And in RootCommands.java file (should not be an inner class):
Code:
package com.bassel.example;
import com.bassel.cmd.Command;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
public class Main extends Command
{
private byte[] buffer;
private File recovery, partition;
private FileInputStream in;
private FileOutputStream out;
//static main method implementation is a must
@Override
public static void main(String[] args)
{
//required to start
new Main().run(args);
}
//the begging just like onCreate
@Override
public void onRun()
{
if(argsCount() < 2) showUsage();
System.out.println(String.format("Flashing %s to %s", getArg(0), getArg(1)));
recovery = new File(nextArg());
partition = new File(nextArg());
buffer = new byte[1024 * 1024];
try
{
in = new FileInputStream(recovery);
out = new FileOutputStream(partition);
while(in.read(buffer) > 0)
{
out.write(buffer);
out.flush();
}
in.close();
out.close();
System.out.println("Flashed successfully!");
}
catch (Exception e)
{e.printStackTrace(System.err);}
}
//called upon calling showUsage()
@Override
public void onShowUsage()
{
System.err.println("Two args are needed!");
}
//called once an exception is caught
@Override
public void onExceptionCaught(Exception exception)
{
exception.printStackTrace(System.err);
}
}
Quite lengthy but sometimes we prefer using Java codes to bash ones, don't we?
Here is another example for listing /data files:
Code:
package com.bassel. example;
import java.io.File;
//Without extending Command.class
public class Main
{
@Override
public static void main(String[] args)
{
String[] files = new File("/data").list();
for(String file : files)
{
System.out.println(file);
}
}
}
Usage in depth:
Check root access:
Cmd.root();
No root:
Cmd.SH.ex(String command, String... args);
Cmd.SH.ex(String[] commands);
Cmd.SH.ex(List commands);
With root access:
Cmd.SU.ex(String command, String... args);
Cmd.SU.ex(String[] commands);
Cmd.SU.ex(List commands);
JavaRoot java = JavaRoot.newInstance(String packageName, String className, boolean isSystemApp);
java.execute(String... args);
java.executeInBackground(String... args);
All previous methods aside of the last one:
java.executeInBackground(String... args);
return an instance of type Output that has the following methods:
Code:
boolean success() //returns true if process exit value = 0 else false
String getString() //returns output in String format
String[] getArray() //returns output in String Array format
List getList() //returns output in String List format
int getExitValue() //returns process exit value
String toString() //returns process status and output in String format
Converting:
String string = ...;
String[] array = ...;
List list = ...;
String s1 = Convert.array2string(array);
String s2 = Convert.list2string(list);
String[] a1 = Convert.list2array(list);
String[] a2 = Convert.string2array(string);
List l1 = Convert.array2list(array);
List l2 = Convert.string2list(string);

Help me translate this coding

I'm learning how to manage data that I pull from DB (MYSQL) from this coding. I tried to figure out from free source coding but got stuck on this function, can anybody explain to me flow of this coding?
Code:
protected void onPostExecute(Void aVoid) {
name = names.split(":");
email = emails.split(":");
phone = phones.split(":");
combinedArray = combinedText.split(":");
listView.setAdapter(new ArrayAdapter<String>(RetrieveData.this,
android.R.layout.simple_list_item_1, combinedArray));
progressDialog.dismiss();
}
and when I tried to use this code, red line prompt out and saying that cannot resolved this constructor on if i change
Code:
listItems
to
Code:
names
variables on this
Code:
adapter=new ArrayAdapter<String>(this,
R.layout.list_item, R.id.txtitem, listItems);
I don't understand why I need to use 'split' to pull out the output on listview.
