[Guide] Accessing all Build.prop values without Root - Java for Android App Development

[Guide] Accessing all Build.prop values without Root - Java for Android App Development

Hi.
I was developing an app in which I needed to access some of the build.prop values without accessing root.
After some days finally I found a good & working solution.
So, for whom they need it later, I decided to share it here.
All you have to do is this :
1. Make a process which executes "getprop" from the "/system/bin/getprop" directory and initialize the String which we want to get (ro.board.platform in example).
2. Make a BufferedReader which gets the value (String) by retrieving the data from a inputStreamReader().
3.Convert the BufferedReader to String.
Help your selves.
Code:
Process p = null;
String board_platform = "";
try {
p = new ProcessBuilder("/system/bin/getprop", "ro.board.platform").redirectErrorStream(true).start();
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line=br.readLine()) != null){
board_platform = line;
}
p.destroy();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Thanks man!.,,..

But are we really in such a need of getprop? If I remember correctly, on all Android devices /system partition is world-readable. So we can just read it build.prop like a normal text file and then parse it.

Maybe you're right.
But before the Tut، I collected some info on build.prop.
I read different files from different devices with different ROMs.
And I gained a result : The file differs from ROM to ROM and from device to device.
I had thought of this knowing that in device Nexus 4 "ro.x.y" is in line "z" forexample :
1. Create BufferedReader to read the build.prop file.
2.
// Let's consider ro.x.y : outcome in build.prop
int x = 0;
String y ="";
If ((y = br.readLine()) != null) {
x++;
String line = y;
if (x = z){
// So we have found ro.x.y
String result = line;
result = result.replaceAll("ro.x.y", "");
result = result.replaceAll(" :", "");
}
}
Using this procedure we have retreived the ro.x.y value in Nexus 4.
But does anybody promise that ro.x.y is in line "z" in all devices?
The answer is NO as I mentioned above.
Maybe someone has changed his build.prop file and ... .
I hope it helps.

Thanks sir.
Didn't notice at all.

And here is C# Translation for the code:
------------------------------------------------------------------------------------------------
Global Variables
------------------------------------------------------------------------------------------------
Code:
private Process p = null;
private string AdbPath = Path.Combine(Path.GetTempPath(), "RegawMOD", "AndroidLib", "adb");
------------------------------------------------------------------------------------------------
Process Definition
------------------------------------------------------------------------------------------------
Code:
try
{
p = new Process();
ProcessStartInfo sInfo = new ProcessStartInfo("cmd");
sInfo.RedirectStandardOutput = true;
sInfo.RedirectStandardInput = true;
sInfo.CreateNoWindow = true;
sInfo.UseShellExecute = false;
sInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.StartInfo = sInfo;
p.OutputDataReceived += p_OutputDataReceived;
p.EnableRaisingEvents = true;
p.Start();
p.BeginOutputReadLine();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error starting adb process", MessageBoxButton.OK, MessageBoxImage.Error);
}
------------------------------------------------------------------------------------------------
p_OutputDataReceived Definition
------------------------------------------------------------------------------------------------
Code:
void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
string line = "";
try
{
if (!(line = e.Data).Trim().Length.Equals(0) && !line.Contains("/system/bin/getprop ro.board.platform"))
{
this.Dispatcher.BeginInvoke(new Action(() => txt.AppendText(line + "\n")));
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error Reading Output", MessageBoxButton.OK, MessageBoxImage.Error);
}
}
------------------------------------------------------------------------------------------------
Passing command to our little adb process
------------------------------------------------------------------------------------------------
Code:
if (p != null)
{
p.StandardInput.WriteLine(AdbPath + " shell /system/bin/getprop ro.board.platform");
}
------------------------------------------------------------------------------------------------
Side Notes:
------------------------------------------------------------------------------------------------
Code above will result in active shell, it's a simulation for executing commands via CMD
What you need to do is the following:
Change "AdbPath" content to match the path of your adb executable.
"txt" is the Textbox that will show the output, put your own object.
Remove this line " !line.Contains("/system/bin/getprop ro.board.platform);" from "p_OutputDataReceived" to have an idea why I included it in the first place, it's not a must to have it but it will make output look nicer.
In the "Passing command to our little adb process" section, you can replace " shell /system ...etc" with your own object to make the app flexible and be able to execute any command the user type [example: .p.StandardInput.WriteLine(String.Join(" ", AdbPath , CommandTextBox.Text));]
This is almost the same code I execute in Droid Manager for the active shell, I just added few more lines to serve my active shell demands
My device is rooted, nevertheless it doesn't matter which language we are using, as long as we are executing the same command, then it should work with non rooted devices too just like OP says
I use AndroidLib that's why my Adb path points to AndroidLib's adb executable.
------------------------------------------------------------------------------------------------
Good luck
------------------------------------------------------------------------------------------------

@Dr.Alexander_Breen Yes /system is read only and we can read the file, but if you read it like a text file you will have to break text apart to get the value and not key + value. and you will have to go line by line to reach the key you want, so by using "getprop" you will get the value without having to write extra lines of code to make the app show you value only. As for me I prefer it that way, no need to make the app execute more lines of code just to get a part of the string.

Well, we are supposed to write smart parser which is indifferent to line number, it searches by key name...and gets the value. However, that is the reinvention of the wheel - getprop does exactly the same.
Just saying that the same result is available without the getprop. But it will be (or will not if you're really good in regular expressions) harder, yes.

Alternatively, you can use reflection to access Android's internal android.os.SystemProperties class.

Then, you can create a static method like the following in order to avoid NPEs if the property we're asking for isn't present and such:
Code:
public static String getSystemProp(Context context, String prop, String default) {
String result = null;
try {
result = SystemPropertiesReflection.get(context, prop);
} catch (IllegalArgumentException iae) {
Log.e(TAG, "Failed to get prop: " + prop);
}
return result == null ? default : result;
}
And simply invoke it to get the returned property, for example:
Code:
String prop = getSystemProp(this, "ro.sf.lcd_density", "213");
EDIT : sorry to the guys that were @ mentionned by the code's annotations

@ whoever's code I decide to use: Thanks, I'll make use of this in my library I'll put you in the credits :good:

I'm using the code in the OP and it's returning the default value, but not the actual value... This is really weird...
EDIT: Ok, so it won't update values until I reboot the device. Is there any workaround?

The system properties are not reloaded after you edit the build.prop, you need a reboot, or you've to read from build.prop file.

But whenever I read directly from build.prop something screws up, like build.prop becomes empty or deletes itself. In my last test my sdcard became corrupted and build.prop became blank.

Use setprop and getprop in addition to the changes you make to the build.prop, this way you can get the current value without the hassle or performance loss of having to parse the whole build.prop for each value you want to read.
For example, if you change ro.whatever=true to ro.whatever=false, also do a setprop ro.whatever false so that you can retrieve the value from getprop ro.whatever

If this is true (and i think it is), why <ou don't simply use the Java Properties class to read the prop file?
developer.android.com/reference/java/util/Properties.html
Sorry for answering in this old Thread, but i dont see why you read the properties file by yourself.

Yeah, it should work, in theory.. But in practice it screw things up a lot. It ends up deleting the whole contents of build.prop or not reading correctly and it's very unpredictable :-/
And yes I was using the Properties class (and still do)

Then you're not doing it right, it does work, and it's very easy to test, just open Terminal emulator, and try the following:
Code:
setprop ro.test.prop true
getprop ro.test.prop
# returns
true
As I said, this will not modify the build.prop, but if everytime you modify the build.prop you also use setprop, then you can avoir the big performance overhead of having to parse the whole build.prop just to get the value of a single prop.
The best way to me remains accessing the private android.os.SystemProperties class through reflection. I believe I had already posted the class in this thread earlier, but here it is:

Hi.
I was developing an app in which I needed to access some of the build.prop values without accessing root.
After some days finally I found a good & working solution.
So, for whom they need it later, I decided to share it here.
All you have to do is this :
1. Make a process which executes "getprop" from the "/system/bin/getprop" directory and initialize the String which we want to get (ro.board.platform in example).
2. Make a BufferedReader which gets the value (String) by retrieving the data from a inputStreamReader().
3.Convert the BufferedReader to String.
Help your selves.
Code:
Process p = null;
String board_platform = "";
try {
p = new ProcessBuilder("/system/bin/getprop", "ro.board.platform").redirectErrorStream(true).start();

Hi, Is anyone nood friendly to explain me or some tutorial where and how to put this comand, to change my build.prop without unlocking bootloader on my HOX tegra 3..grateful for any response

Hi.
I was developing an app in which I needed to access some of the build.prop values without accessing root.
After some days finally I found a good & working solution.
So, for whom they need it later, I decided to share it here.
All you have to do is this :
1. Make a process which executes "getprop" from the "/system/bin/getprop" directory and initialize the String which we want to get (ro.board.platform in example).
2. Make a BufferedReader which gets the value (String) by retrieving the data from a inputStreamReader().
3.Convert the BufferedReader to String.
Help your selves.
Code:
Process p = null;
String board_platform = "";
try {
p = new ProcessBuilder("/system/bin/getprop", "ro.board.platform").redirectErrorStream(true).start();
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line=br.readLine()) != null){
board_platform = line;
}
p.destroy();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

Hey,
Sorry for bumping this old thread.
How a non-developer user could use this to change/add build.prop lines?
I got a complete stock Nexus 5X that I'd like to add some new lines into build.prop without root.
Is it possible?
Thanks in advance!

How to integrate that to show in textView?

How SEUS Flashing Works

OK, so been trying to figure out what happens when you use SEUS.
It checks for internet connection by loading this URL:
Code:
http://emma.extranet.sonyericsson.com/ns/no-cache
I've figured out quite a bit.
Sony Ericsson has implemented something called Tampered Device Service.
This checks if the devices has been tampered with.
This service works from this server:
Code:
tds.sonyericsson.com
Then for the actual firmware download.
This is done by downloading 2 *.ser.gz which tells SEUS what Software customization to get and is sessions specific.
The customization ser.gz file looks something like this:
Code:
CDA=1233-7027_NjKhzOzTUsfXvPg40lyh6aTl.ser.gz
And it's downloaded from:
Code:
emma.extranet.sonyericsson.com
It's done via some sort of search mechanism on the server.
That looks like this:
Code:
ns/usdoe1/2/script/search/TAC8=35941903/CDA=1233-7027_By5JACZqd1R7JOpLu6qvwK8N.ser.gz
After that it's downloading the actual firmware files.
They are downloaded in bin format which I haven't been able to unpack yet.
They are also downloaded from the emma server and is named something like:
Code:
277795427_k9ABo3YVh+8klYUKwllGLDcJ.bin - ~14.3 MB
277835617_ZpJseUr9e09U5h2Cz81+5vcT.bin ~149 MB
Then it does a netbios call which has some sort of HEX code.
And then check the Internet connection again:
Code:
http://emma.extranet.sonyericsson.com/ns/no-cache
Now it starts up a service called:
Code:
/fq/ServiceClientDbServlet
This service runs from this server:
Code:
ma3.extranet.sonyericsson.com
This last part is done twice in a row.
Inside one of the *ser.gz files is a *.ser file which contains some code and instructions. Some parts is encrypted but most of the code is not.
See the complete code in post #2
I don't quite know what to do with all this info yet.
But hopefully something useful will come of this.
Just wanted to share a bit of my knowledge, hope it's useful for some of you here.

wow seems u done some packet sniffing...
may be u should contact Bin4ry regarding this... he is involved in FreeXperia Project for Arc/Play...
i am sure he can shed some more light on this matter...

Figured out the *.bin files is the actual files that also goes in the blob_fs folder:
Code:
%programfiles%\Sony Ericsson\Update Service\db\
So they are decryptable using the known method.

Tampered Device Service does in fact check for Root and custom software.
Don't know if this will have an effect in the updating process from SEUS.

So, it's a bad news huh. Keep looking. Thanks for the info.

Confirmed that devices that has been rooted and modified in software will not be eligible for 2.3.3 update. You will have to flash back a stock unrooted firmware before updating to 2.3.3

Of course. SE said that in their blog. Better backup all data in SD Card and format it too. I don't think the SEUS' intelligent enough to check out that the SD Card contains CyanogenMod folder as busybox and xRecovery
EDIT: I tried to find the update 2.1 package in my computer after repaired my phone for several times and I can't find it. It's of course that it's deleted as soon as the update completed.

I believe SEUS works like the Flash Tool and Pay-Per-Update service through fastgsm.com and davince.
Flash Tool requires you to provide the firmware and place the sin files in the correct location.
Pay service requires a fee to install the correct sin files/firmware.
SEUS requires a CDA to determine which sin files/firmware to install.

I beg that the FlashTool works like SEUS cause without SEUS and other update services, where is FlashTool come from?

But what if SEUS change its method? Well, i still want to update and we will see how it goes.

Whatever method they choose, they can't close the door behind them. They need the access too. Flash Tool can be updated.
Nor would google allow that. JMHO

Yes, FT can be updated but it's development is kinda dead as of now, and we don't even have its source codes, so the other developers can't update it. Unless if Androxyde and Bin4ry want to work on FT again.

Why are the devs acting like this is an issue? The Flash Tool already works on the ARC, so what are you worried about?

Work on Arc no mean it can work on X10, just like Arc has bootloader unlocked but no mean X10 can when update to 2.3.3

You totally missed the point. The bootloader or root has NEVER mattered. When the NEVER has happened, then start your *****ing.

What I mean is that IF SE changed their flashing method for the GB firmware and FT won't work for those who upgraded their X10 to GB. But another user has said that they won't since it requires them to start all over again.
Who knows, we're not the one who are developing the firmwares and we all should stop making assumptions(but some people aren't making assumptions, they are so sure they are right).

I am not pretending to know. However, you are failing to acknowledge that the Flash Tool is a modification of Update Service. The same method is used. Quit acting like this is nuclear science.

I told you, what IF they CHANGE the flashing method, then SEUS will also be updated with the new method.
Why am I repeating this anyway? Silly me.

How can I loop through my JSON object?

I am new to Java and I am getting kind of stuck by trying to loop through my JSON. I am retrieving a JSON object where I want to loop through.
My JSON looks as follow:
Code:
{"message":{"2":[{"uid":"2","title":"","message":"Test1","success":1,"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !","success":1,"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","success":1,"created_at":null,"updated_at":null}]}}
I tried a loop like this:
Code:
for(int i = 0; i<json.names().length(); i++){
try {
Log.v("TEST", "key = " + json.names().getString(i) + " value = " + json.get(json.names().getString(i)));
} catch (JSONException e) {
e.printStackTrace();
}
}
But this will only target "message" which includes the whole JSON "string". I want to loop through each message and retrieving the value of uid 1, uid 2 etc. How can I achieve this?
Thanks in advance.

Here is how I'm doing it:
Code:
private static final String AllNewsItemsURL = "some_url_here.php";
private static final String TAG_SUCCESS = "success";
private static final String NEWS = "news";
private static final String TITLE = "title";
private static final String STORY = "story";
private final JSONParser jParser = new JSONParser();
private JSONArray newsItems = null;
..... / code snipped / ....
try {
JSONObject json = jParser.makeHttpRequest(AllNewsItemsURL, params);
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
newsItems = json.getJSONArray(NEWS);
for (int i = 0; i < newsItems.length(); i++) {
JSONObject obj = newsItems.getJSONObject(i);
Integer id = i + 1;
String title = obj.getString(TITLE);
String story = obj.getString(STORY);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}

Thanks for your reply. I tried it but getting this exception:
Code:
org.json.JSONException: Value {"2":[{"uid":"2","title":"","message":"Test1","success":1,"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2","success":1,"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3","success":1,"created_at":null,"updated_at":null}]} at messages of type org.json.JSONObject cannot be converted to JSONArray

You might want to try the matching JSONParser I have for it, sorry forgot to include it:
https://github.com/JonnyXDA/WGSB/bl...om/jonny/wgsb/material/parser/JSONParser.java
Also noting that your entire JSON Array is called "message" but you also have a parameter called "message" - maybe rename the Array to "messages"?
As for the code you should have something like:
Code:
private static final String AllNewsItemsURL = "some_url_here.php";
private static final String TAG_SUCCESS = "success";
private static final String MESSAGES = "messages";
private static final String TITLE = "title";
private static final String MESSAGE = "message";
private final JSONParser jParser = new JSONParser();
private JSONArray messageItems = null;
..... / code snipped / ....
try {
JSONObject json = jParser.makeHttpRequest(AllNewsItemsURL, params);
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}

My code looks like the this:
Code:
//Message task
MessageTask task = new MessageTask(DashboardActivity.class);
task.execute();
try {
json = task.get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}
I am using Async Task to retrieve my JSON.
And my JSON parser looks like this:
Code:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
But it doesn't get through the if statement, because it can't find the value success. ( org.json.JSONException: No value for success ). Don't really know what I am doing wrong here. Is it because I am using AsyncTask and retrieving my JSON the wrong way?
I also renamed my Array to "messages", stupid mistake thanks!

We're getting closer! With regards to using AsyncTask - thats fine and the recommended way to do service side sync/download operations (doesn't block the UI thread) so no need to change that.
I just took a look at my reference JSON and I have the success tag outside of an item eg:
Code:
{"topical":[{"tid":"5","title":"Exam countdown... just 12 weeks left!","story":"some_story_text_here","staff":"0","red":"0","show":"1"}],[COLOR="red"]"success":1[/COLOR]}
Whereas your success tag is put in each item:
Code:
{"message":{"2":[{"uid":"2","title":"","message":"Test1","[COLOR="red"]success":1,[/COLOR]"created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !",[COLOR="red"]"success":1[/COLOR],"created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","[COLOR="Red"]success":1[/COLOR],"created_at":null,"updated_at":null}]}}
I'm guessing that your php line for:
PHP:
$response["success"] = 1;
is inside of the while loop:
PHP:
while ($row = mysql_fetch_array($result)) {
Taking it out of the while loop should fix that

That makes sense, because I am trying to get a success code for my whole JSON response. I changed my PHP code to:
Code:
while($row = mysqli_fetch_array( $messages )) {
// create rowArr
$rowArr = array(
'uid' => $row['id'],
'title' => $row['title'],
'message' => $row["message"],
'created_at' => $row['created_at'],
'updated_at' => $row['updated_at'],
);
// store rowArr in $return_arr
$return_arr[$row['id']][] = $rowArr;
}
$return_arr['success'] = 1;
// Json encode
echo json_encode(array("messages" => $return_arr));
}
Retrieving the following JSON:
Code:
{"messages":{"2":[{"uid":"2","title":"","message":"Test1","created_at":null,"updated_at":null}],"3":[{"uid":"3","title":"","message":"Test2 !","created_at":null,"updated_at":null}],"4":[{"uid":"4","title":"Bla","message":"Test3!","created_at":null,"updated_at":null}],"success":1}}
But I am still getting the following exception:
Code:
org.json.JSONException: No value for success

The success tag is still being encoded as part of an inner array, not the first array - try this:
PHP:
if (mysql_num_rows($messages) > 0) {
$response["messages"] = array();
while ($row = mysql_fetch_array($messages)) {
$messagesArray= array(
'uid' => $row['id'],
'title' => $row['title'],
'message' => $row['message'],
'created_at' => $row['created_at'],
'updated_at' => $row['updated_at'],
);
array_push($response["messages"], $messagesArray);
}
$response["success"] = 1;
echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "No messages found";
echo json_encode($response);
}

And it's finally working!
Getting the following JSON result:
Code:
{"tag":"message","success":1,"error":0,"messages":[{"uid":"2","title":"","message":"Test1","created_at":null,"updated_at":null},{"uid":"3","title":"","message":"Test2!","created_at":null,"updated_at":null},{"uid":"4","title":"Bla","message":"Test3!","created_at":null,"updated_at":null}]}
And I can successfully loop through my JSON with the following code:
Code:
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
messageItems = json.getJSONArray(MESSAGES);
for (int i = 0; i < messageItems.length(); i++) {
JSONObject obj = messageItems.getJSONObject(i);
String title = obj.getString(TITLE);
String message = obj.getString(MESSAGE);
Log.e("TITLE :", title);
Log.e("MESSAGE :", message);
}
} else {
Log.e("JSON Response", "success == 0");
}
} catch (Exception e) {
e.printStackTrace();
}
Thank you very much! So the problem was that I placed the "success" tag outside my Array?
