RootTools Read Output - Java for Android App Development

RootTools Read Output - Java for Android App Development

I want to read a command output but I can't do it:
Code:
Command command = new Command(0, "echo this is a command", "echo this is another command") {
@override
public void output(int id, String line) {
//tv.setText(line);
//This ^ give me RunTime error
}
};
RootTools.getShell(true).add(command);
I want to read the command output and put it in a TextView, but I dont want to use shared prefferences becouse I don't want that the user can read this information and becouse I need to put a lot of code to read and write in it.
Any Ideas???

Now I'm not in my PC, but it gives me a RunTime error, I think is very similar as change a TextView in background AsynkTask.
Thanks!

That was my guess, too. So try this:
Code:
final StringBuilder s = new StringBuilder();
Command command = new Command(0, "echo this is a command", "echo this is another command") {
@override
public void output(int id, String line) {
s.append(line);
}
};
RootTools.getShell(true).add(command).waitForFinish();
tv.setText(s.toString());

It doesn't work ;( The string is empty! Only works if I put a log in public void output, out of it, it does't work!

It does work. I just tested it in Eclipse.
My Activity:
Code:
package com.example.testers;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import com.stericson.RootTools.RootTools;
import com.stericson.RootTools.execution.Command;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
TextView tv = (TextView) findViewById(R.id.hello_world);
final StringBuilder s = new StringBuilder();
Command command = new Command(0, "echo this is a command", "echo this is another command") {
@Override
public void output(int id, String line) {
s.append(line);
}
};
RootTools.getShell(true).add(command).waitForFinish();
tv.setText(s.toString());
} catch (Exception e) {
}
}
}
and the layout:
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin">
<TextView
android:text="@string/hello_world"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/hello_world"/>
</RelativeLayout>

OK, we don't need it if you've already solved it.
But could you please post that in the future? Thanks.

Yeha, but I post it for two reasons:
- You can show how can I solved it
- To the newbies, the can learn with it

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
it's not perfect, could be tricky, but i can't post all the code here

first you'll have to copy the file from the apk-assets folder to /data/data/your.pqackage.name/file/file.format, after that you can copy it as root to the system partition.
Code:
String data_storage_root = mContext.getFilesDir().toString();
InputStream is= null;
OutputStream os = null;
File h = new File(data_storage_root+"/file.format");
if (h.exists()) h.setWritable(true, true);
try {
is = mContext.getResources().getAssets().open("keypad/file.format");
os = new FileOutputStream(data_storage_root+"/file.format");
IOUtils.copy(is, os);
is.close();
os.flush();
os.close();
os = null;
Log.d(TAG, "success copying");
} catch (IOException e) {
Log.w(TAG, "failed copying");
}
h.setExecutable(false, true);
h.setReadable(true, true);
h.setWritable(false, true);

Thanks for the info, I didn't know it!
When I use this code I have two issues, in mContext and IOUtils, what am I doing wrong?
And Copying from data to system I preffer doing it with RootTools. Can u help me pls??

Oh, sorry. This is a snipplet from one of my apps, it uses a library called commons-io-2.1.jar for the IOUtils. The context is just the context from the loader where this snipplet comes from.
I've never used RootUtils so I can't help you with that, sorry.
When I'm not on my phone but at a computer I'll search for an alternative to extract the file from the apk for you (if you haven't found it by then, SO will have an answer for sure).

This is all my code, I use your library and RootTool library.
I have two issues:
1- Error in waitForFinish();
2- processDialog don't appear.

Hi,
I've rewrote my snipplet not to use the apache library (eventually it is just one method that was used so this is more clean) and added that to a asynctask.
Better late than never now you have rewritten yours as well :S Attached is the eclipse project.
Also, in your code you are trying to copy two files, that is not going to work like that. You define the inputstream and the outputstream twice. I will make this thing work for you if you haven't figured it out tomorrow, will take 24 hrs for me to come back on this. I don't use roottools as I said but maybe I'll look into that as well. Else I will give you an alternative.

I'm frustrated... You change the name of my functions an now I don't understand anything.
public void reparar is the name of the button function, in your code the functions starts "onCreate".
I prefer my dirty but understable (for me) code
Now I have only one problem, the app works, but it take a long time to reemplace the file in system directory. In other words, I pulse the button, close the application, an in one minute the file is reemplaced. How can I fix that an take this time in a progress dialog?
Sorry for my bad english! I'm spanish
This is my code, is dirty but I think you understand it. Add functions and edit, but no the name of the functions, Please!

Hi, I haven't had time to produce more code for you.
Just some remarks looking at your code:
1 you duplicate a lot of code
2 your application does everything on the main thread
3 you do a lot of unnescasairy code on the terminal
1)
copyfle 1 and 2 are almost the same, why not use it only once? copyFile(String filename){ ... } for example?
2)
extracting the files form the apk to /data schould be done at the loading of the app, in the background and preferably only once (now it tis done everytime the app starts), then copy it to system at a press of the button. In my example there is a function doneBackground(boolean succes), from there you could set the visiblity of your button to View.VISIBLE, allowing the user to copy the file to /system, now everything is done after the button press.
3)
Code:
"su"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
"cp /data/data/com.fixer.gminipop/files/sec_key.kl /system/usr/keylayout/sec_key.kl"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system")
"su"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system"
"cp /data/data/com.fixer.gminipop/files/sec_keypad.kl /system/usr/keylayout/sec_keypad.kl"
"mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system");
this calls 2 times su and it mounts 2 times the system as rw and back to ro, can hugely be optimized
Edit, just read Nikwens reply in your other thread, you don't have to call su at all according to him. However,as I said, I am not a user of Roottools so can't confirm that.

Thank's! I'm going to fix that, Optimice code and clear it. But the problem persist, the copy of the file to system take a long time, and the process to do it is after I close the app, This is my only important error..

You should get someone to translate all that Spanish to English. I took the effort to translate it for myself (with Google translator) but I'm sure the advantage potential user won't.

I see that you can write English.
However, you might want to have it translated to other languages, too.

Create the directory using the mkdir() method in the java.io.File class. And copy every file to the directory in /data/data. You need to copy the files one by one.

Need help in saving data from app

Code:
import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.*;
import java.io.*;
public class MainActivity extends Activity
{
/** Called when the activity is first created. */
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}public void save(View view){
EditText e=(EditText) findViewById(R.id.editText1);
String a=String.valueOf(((e.getText().toString())));
try{FileOutputStream s=new FileOutputStream("/data/data/com.mycompany.myapp/first.sav");
ObjectOutputStream save= new ObjectOutputStream(s);
save.writeObject(a);}
catch(Exception f){e.setText(""+f);}
}
}
This code saves the entered data in first.sav file. But if i add different data again, it replaces the earlier saved data but i want both the older and newer saved. How to do it

You mean appending some new text to your existing file?
Code:
try {
PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("/data/data/com.mycompany.myapp/first.sav", true)));
out.println("the text");
out.close();
} catch (IOException e) {
e.setText(""+e);
}

you can use Filewriter like this
FileWriter fw = new FileWriter(filename,true);

the 2nd parameter will open file in append mode.

As per Developer's site:
Code:
FileOutputStream(String path, boolean append)
Constructs a new FileOutputStream that writes to path.
http://developer.android.com/reference/java/io/FileOutputStream.html
Using your current code, just add true to your FileOutputStream

[Q] Same shell command works from console and doesn't work from Activity

//sorry for my english, if any
Hi. I'm using AIDE right on my device (Xperia NeoV, 4.1.B.0.587, root)
And i'm trying to inject key events through the same shell command:
"input keyevent 25" via "su", both in AIDE Console and separated Activity.
//volume-down key is not my target, just good for tests. I've tried different keys, same result.
Part of the code:
Code:
try {
java.lang.Process p = Runtime.getRuntime().exec("su");
DataOutputStream dos = new DataOutputStream(p.getOutputStream());
dos.writeBytes("input keyevent 25\n");
dos.flush();
} catch (IOException ex) {
//log any errors
}
So, when it goes in AIDE ConsoleApp - it pushes down volume.
But when it executes from my Activity - nothing happens (no error messages in log, dos != null);
Maybe there should be some specific permission on manifest?
"android.permission.ACCESS_SUPERUSER" - no changes.
Maybe there should be some trick in code? Or(and?) i'm very stupid. Also, maybe somewhere a whole listing of _simple_ keyInjection project exists?

I managed to solve it already. I'm using this class now:
public void RunAsRoot(String[] cmds){
Process p = null;
try {
p = Runtime.getRuntime().exec("su");
} catch (IOException e) {
e.printStackTrace();
}
DataOutputStream os = new DataOutputStream(p.getOutputStream());
for (String tmpCmd : cmds) {
try {
os.writeBytes(tmpCmd+"\n");
} catch (IOException e) {
e.printStackTrace();
}
}
try {
os.writeBytes("exit\n");
} catch (IOException e) {
e.printStackTrace();
}
try {
os.flush();
} catch (IOException e) {
e.printStackTrace();
}

Then simply call it via
String[] commands = {"command1", "command2", "command3", ...};
RunAsRoot(commands);

I saw that thread before creating own, and tried solutions from it. They works same way - only from ConsoleApp in AIDE.
Also, last method is the same as I'm already using, but I've tried to copy code in project - no progress.
In addition:
- superuser rights granted to both.
- test "ls" command put into dos object gives me same list of current dir in both projects, so commands seems to run.

Thanks for participating in solving.
The reason was somewhere else - after executing "export LD_LIBRARY_PATH=/system/lib" all works fine. Thread is over.

[Q] Error receiving Intent from IntentService

I'm trying to make an app that displays and image which will be downloaded in background in an IntentService class. When the IntentService finishes to download it sends the intent to be catched by a BroadcastReceiver in the MainActivity but I'm getting this error:
Code:

This is MainActivity class:
Code:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

};
@Override

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
This is the IntentService class:
Code:
package com.example.matt95.myapplication;
import android.app.IntentService;
import android.content.Intent;
import android.os.Environment;
import android.util.Log;
import android.widget.Toast;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class ImageIntentService extends IntentService {
private File cacheDir;
private static final String CACHE_FOLDER = "/myapp/image_cache/";
public static String TRANSACTION_DONE = "com.example.matt95.myapplication.ImageIntentService.TRANSACTION_DONE";
//Constructor method
public ImageIntentService() {
super("ImageIntentService");
}
@Override
public void onCreate() {
super.onCreate();
String tmpLocation = Environment.getExternalStorageDirectory().getPath() + CACHE_FOLDER;
cacheDir = new File(tmpLocation);
if (!cacheDir.exists())
cacheDir.mkdirs();
}
@Override
protected void onHandleIntent(Intent intent) {
if (intent.hasExtra("url")) {
String remoteUrl = intent.getExtras().getString("url");
String imageLocation;
String fileName = remoteUrl.substring(remoteUrl.lastIndexOf(File.separator) + 1);
File tmpImage = new File(cacheDir + "/" + fileName);
if (tmpImage.exists()) {
imageLocation = tmpImage.getAbsolutePath();
notifyFinished(imageLocation, remoteUrl);
stopSelf();
return;
}
try {
URL url = new URL(remoteUrl);
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
if (httpCon.getResponseCode() != 200)
throw new Exception("Failed to connect");
InputStream is = httpCon.getInputStream();
FileOutputStream fos = new FileOutputStream(tmpImage);
writeStream(is, fos);
fos.flush();
fos.close();
is.close();
imageLocation = tmpImage.getAbsolutePath();
notifyFinished(imageLocation, remoteUrl);
} catch (Exception e) {
Log.e("Service", "Failed!", e);
}
}
}
private void writeStream(InputStream is, OutputStream fos) throws Exception {
byte buffer[] = new byte[80000];
int read = is.read(buffer);
while (read != -1) {
fos.write(buffer, 0, read);
read = is.read(buffer);
}
}
private void notifyFinished(String imageLocation, String remoteUrl) {
Intent i = new Intent(TRANSACTION_DONE);
i.putExtra("imageLocation", imageLocation);
i.putExtra("url", remoteUrl);
ImageIntentService.this.sendBroadcast(i);
}
}
And this is the Manifest file:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.matt95.myapplication" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MyActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".ImageIntentService" />
</application>
</manifest>
What am I doing wrong?

Code:
Caused by: java.lang.NullPointerException
at com.example.matt95.myapplication.MyActivity$1.onReceive(MyActivity.java:74)
tells you there, you are asking an object that is of type "x" that is NULL to do something on line 74

Why not just use the picasso library or similar to download the image asynchronously in the background?

I'm a beginner in Android application so I don't have the proper knowledge right now, thanks for the suggestion though, I'll definitely try to take a look at that library :good:

Yeah but I also need to download it and then load it, and it's not good to download that amount of data on the main thread

AsyncTask runs in the background on a separate thread via the doInBackground method.

Also, when there is a possibility that one of the objects included in the intent is null you can trap the error with a try/catch around the sendBroadcast() to prevent the exception from crashing the entire app.
