Hi everyone.
I want to retrieve the current cpu frequency in my app but I don't seem to be right.
In my code I want to read the "scaling_cpu_freq" file from internal storage.
This is the code:
Code:
private String ReadCPUMhz() {
String cpuMaxFreq = "";
int cur = 0;
try {
[user=1299008]@supp[/user]ressWarnings("resource")
BufferedReader maxi = new BufferedReader(new FileReader(new File("/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq")));
try{
cpuMaxFreq = maxi.readLine();
cur = Integer.parseInt(cpuMaxFreq);
cur = cur/1000;
} catch (Exception ex){
ex.printStackTrace();
}
} catch (FileNotFoundException f) {
f.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return String.valueOf(cur);
}
The problem is that the method only returns 0, which is the initial value of the int "cur".
Can anybody help me?
Thanks in advance.
Here's the code I use:
Declare this class in your Activity
Code:
// Read current frequency from /sys in a separate thread
// This class assumes your TextView is declared and referenced in the OnCreate of the class this one is declared in
// And its variable name is mCurCpuFreq
protected class CurCPUThread extends Thread {
private static final String CURRENT_CPU = "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq";
private boolean mInterrupt = false;
public void interrupt() {
mInterrupt = true;
}
[user=439709]@override[/user]
public void run() {
try {
while (!mInterrupt) {
sleep(400);
final String curFreq = readOneLine(CURRENT_CPU);
mCurCPUHandler.sendMessage(mCurCPUHandler.obtainMessage(0,
curFreq));
}
} catch (InterruptedException e) {
return;
}
}
}
// Update real-time current frequency & stats in a separate thread
protected static Handler mCurCPUHandler = new Handler() {
public void handleMessage(Message msg) {
mCurFreq.setText(toMHz((String) msg.obj));
final int p = Integer.parseInt((String) msg.obj);
new Thread(new Runnable() {
public void run() {
// Here I update a real-time graph of the current freq
}
}
}).start();
}
};
Helper methods used :
Code:
// Convert raw collected values to formatted MhZ
private static String toMHz(String mhzString) {
if (Integer.valueOf(mhzString) != null)
return String.valueOf(Integer.valueOf(mhzString) / 1000) + " MHz";
else
return "NaN";
}
// Iterate through the /sys file
public static String readOneLine(String fname) {
BufferedReader br;
String line = null;
try {
br = new BufferedReader(new FileReader(fname), 512);
try {
line = br.readLine();
} finally {
br.close();
}
} catch (Exception e) {
Log.e(TAG, "IO Exception when reading sys file", e);
// attempt to do magic!
return readFileViaShell(fname, true);
}
return line;
}
// Backup method if the above one fails
public static String readFileViaShell(String filePath, boolean useSu) {
CommandResult cr = null;
if (useSu) {
cr = new CMDProcessor().runSuCommand("cat " + filePath);
} else {
cr = new CMDProcessor().runShellCommand("cat " + filePath);
}
if (cr.success())
return cr.getStdout();
return null;
}

I'm an experienced developer but new to Android development. I have an app that runs some native binaries, and I provide a status indicator to show when the native process is running and when it's not. Currently I poll the device to figure this out, using the ActivityManager API to determine if specific processes are running or not.
I'm hoping there is some way to register a listener on process state changes, so I can get notified when my process starts or stops. I looked through the API, and there doesn't seem to be such a thing. Does anyone know how I can keep track of process start and stop other than polling via ActivityManager?

Afaik there's no way to accomplish that other than your way or being system/root app. See this similar question here for reference.
Can you show how you start the process?

Sure. Here's the class that manages starting, stopping, and statusing (running or not) the binary executable. In this case, it's the omniNames service of the omni ORB (CORBA broker).
Code:
public class RHManager {
private TimerTask task = new TimerTask() {
@Override
public void run() {
if (RHManager.this.listener != null) {
listener.running(isOmniNamesRunning());
}
}
};
private IStatusListener listener;
public RHManager() {
}
public void startOmniNames() {
final Exec exec = new Exec();
final String[] args = new String[]
{RhMgrConstants.INSTALL_LOCATION_OMNI_NAMES_SCRIPTS + "/" + RhMgrConstants.OMNI_NAMES_SCRIPT_FILE,
"start"};
final String[] env = new String[] {"LD_LIBRARY_PATH=/sdcard/data/com.axiosengineering.rhmanager/omniORB/lib"};
Thread t = new Thread() {
public void run() {
try {
int res = exec.doExec(args, env);
logMsg("omniNames start return code " + res);
} catch (IOException e) {
logMsg("Failed to start omniNames");
e.printStackTrace();
}
String std = exec.getOutResult();
logMsg("omniNames start: std out==> " + std );
String err = exec.getErrResult();
logMsg("omniNames start: err out==> " + err );
};
};
t.start();
logMsg("omniNames started");
}
private boolean isOmniNamesRunning() {
String pid_s = getOmniNamesPid();
Integer pid = null;
if (pid_s != null) {
try {
pid = Integer.parseInt(pid_s);
} catch (NumberFormatException e) {
return false;
}
}
if (pid != null) {
RunningAppProcessInfo activityMgr = new ActivityManager.RunningAppProcessInfo("omniNames", pid, null);
return activityMgr.processName != null ;
}
return false;
}
public void stopOmniNames() {
String pid = getOmniNamesPid();
android.os.Process.killProcess(Integer.parseInt(pid));
android.os.Process.sendSignal(Integer.parseInt(pid), android.os.Process.SIGNAL_KILL);
}
private String getOmniNamesPid() {
Exec exec = new Exec();
final String[] args = new String[]
{RhMgrConstants.INSTALL_LOCATION_OMNI_NAMES_SCRIPTS + "/" + RhMgrConstants.OMNI_NAMES_SCRIPT_FILE,
"pid"};
String pid = "";
try {
int res = exec.doExec(args, null);
logMsg("oniNames pid return code: " + res);
} catch (IOException e) {
logMsg("Failed to start omniNames");
e.printStackTrace();
return pid;
}
String std = exec.getOutResult();
logMsg("omniNames pid: std out ==> " + std);
String err = exec.getErrResult();
logMsg("omniNames pid: err out ==> " + err);
String[] parts = std.split("\\s+");
if (parts.length >= 2) {
pid = parts[1];
}
return pid;
}
//monitor omniNames status and report status periodically to an IStatusListener
public void startMonitorProcess(IStatusListener listener, String string) {
this.listener = listener;
Timer t = new Timer();
t.schedule(task, 0, 1000);
}
private void logMsg(String msg) {
if (RhMgrConstants.DEBUG) {
System.err.println(msg);
}
}
}
Here's the Exec class that handles invocation of Runtime#exec(), consumes std and err out, and reports those and process return status to the caller.
Code:
public class Exec {
private String outResult;
private String errResult;
private Process process;
private boolean failed = false;
StreamReader outReader;
StreamReader errReader;
public int doExec(String[] cmd, String[] envp) throws IOException{
Timer t = null;
try {
process = Runtime.getRuntime().exec(cmd, envp);
outReader = new StreamReader(process.getInputStream());
outReader.setPriority(10);
errReader = new StreamReader(process.getErrorStream());
outReader.start();
errReader.start();
t = new Timer();
t.schedule(task, 10000);
int status = process.waitFor();
outReader.join();
errReader.join();
StringWriter outWriter = outReader.getResult();
outResult = outWriter.toString();
outWriter.close();
StringWriter errWriter = errReader.getResult();
errResult = errWriter.toString();
errWriter.close();
return (failed ? -1: status);
} catch (InterruptedException e) {
return -1;
} finally {
if (t != null) {
t.cancel();
}
}
}
public int doExec(String[] cmd) throws IOException{
return doExec(cmd, null);
}
public String getOutResult(){
return outResult;
}
public String getErrResult(){
return errResult;
}
private static class StreamReader extends Thread {
private InputStream is;
private StringWriter sw;
StreamReader(InputStream is) {
this.is = is;
sw = new StringWriter(30000);
}
public void run() {
try {
int c;
while ((c = is.read()) != -1){
sw.write(c);
}
}
catch (IOException e) { ; }
}
StringWriter getResult() {
try {
is.close();
} catch (IOException e) {
System.err.println("Unable to close input stream in StreamReader");
}
return sw;
}
}
private TimerTask task = new TimerTask() {
@Override
public void run() {
failed = true;
process.destroy();
}
};
}
Here's the script that startOminNames() invokes. It's the shell script installed with omniORB with functions other than start and get_pid removed, since those are handled by Android classes. You can invoke any executable in place of the script, or wrap your executable in a script.
Code:
#
# omniNames init file for starting up the OMNI Naming service
#
# chkconfig: - 20 80
# description: Starts and stops the OMNI Naming service
#
exec="/sdcard/data/com.axiosengineering.rhmanager/omniORB/bin/omniNames"
prog="omniNames"
logdir="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs"
logfile="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs/omninames-localhost.err.log"
options=" -start -always -logdir $logdir -errlog $logfile"
start() {
#[ -x $exec ] || exit 5
echo -n $"Starting $prog: "
$exec $options
}
get_pid() {
ps | grep omniNames
}
case "$1" in
start)
start && exit 0
$1
;;
pid)
get_pid
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
exit 2
esac
exit $?
And here's the IStatusListener interface
Code:
public interface IStatusListener {
public void running(boolean running);
}
Runtime.exec() has some pitfalls. See this helpful Runtime.exec tutorial for a nice explanation.

i want to save a layout (relative layout), when i run the app everything is working fine, but i am unable to find saved file/s in the internal storage of the phone. Any help would be appreciated as i am new and unable to sort out what is going wrong . here is my code
Code:
public void saveMe(View v) {
// get prompts.xml view
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompt.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialog);
// set dialog message
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
final String fileName = userInput.getText().toString();
final View view1=findViewById(R.id.relativeLayout); // The view that you want to save as an image
Bitmap bitmap = Bitmap.createBitmap(view1.getWidth(), view1.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
view1.draw(c);
if(fileName.length() == 0)
Toast.makeText(EidCardFinal.this,"Please Enter File Name",Toast.LENGTH_SHORT).show();
else{
File file = new File(context.getFilesDir(), fileName);
if (file.exists())
Toast.makeText(EidCardFinal.this,"File Already Exists",Toast.LENGTH_SHORT).show();
else{
try{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, out);
Toast.makeText(EidCardFinal.this,"File Saved",Toast.LENGTH_SHORT).show();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
}
});
alertDialogBuilder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
Try adding a line:
out.flush();
just before calling close() on the FileOutputStream. I think this will get the save code to work, and it's worth trying.

thanks for the suggestion, but i have opted for the external storage and its working fine
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?

send.put("", variable1);
StringEntity se = new StringEntity(send.toString());

"application/json"));
Log.e("test", send.toString());
post.setEntity(se);
response = client.execute(post);

json = new JSONObject(
EntityUtils.toString(response.getEntity()));
}
} catch (Exception e) {
e.printStackTrace();
}
return json;
}
