Why were the three error log files created? - android

I use the following code to catch a global uncaught error, the test code System.out.println(s.equals("any string")); will cause an error.
In my mind, one error log file will be created, but in fact, the three error log files were created with same content, what problem are there in my code?
BTW, I test the code in Android 4.0, only one error log file was generated! but when it run under Android 5.0, three error log files was generated!
MainActivity.java
public class MainActivity extends AppCompatActivity {
private String s;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
System.out.println(s.equals("any string"));
}
}

}

There are different log files in android: Error,Debug,Verbose etc.
And therefore there are different qualifiers for them and they are Log.e,Log.d,Log.v etc. Two of them you are using e and d qualifiers but I don't know about third

Write JSON to a File

I have a class compositionJSON. The class has a method calls makeJSONObject, that creates a JSON-Object and put stuff in it. Here is the code of the class.
public class CompositionJso extends JSONObject {
public JSONObject makeJSONObject (String title, String desc, ArrayList<String> imgPath, ArrayList<Resources> imgView) {
JSONObject obj = new JSONObject() ;
try {
obj.put("title", title);
obj.put("desc", desc);
obj.put("imgPath", imgPath);
obj.put("imgViewPath", imgView);
} catch (JSONException e) {
e.printStackTrace();
}
return obj;
}
Now I create a instance of this class and call the method in another class. After that I want to write the JSONObject to file and save it on the sd card on device. Here is the code:
saveCompo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setName();
createJSONFolder();
CompositionJso obj = new CompositionJso();
obj.makeJSONObject(compoTitle, compoDesc, imgPaths, imageViewPaths);
MyCompositionsListActivity.buildList();
try {
Writer output = null;
File file = new File("storage/sdcard/MyIdea/MyCompositions/" + compoTitle + ".json");
output = new BufferedWriter(new FileWriter(file));
output.write(obj.toString());
output.close();
Toast.makeText(getApplicationContext(), "Composition saved", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
finish();
}
});
The file is saving successfully but if I open it, there is nothing inside. What is wrong with the code?
makeJSONObject is returning JSONObject
Your code should be
saveCompo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setName();
createJSONFolder();
CompositionJso obj = new CompositionJso();
JSONObject jsonObject = obj.makeJSONObject(compoTitle, compoDesc, imgPaths, imageViewPaths);
MyCompositionsListActivity.buildList();
try {
Writer output = null;
File file = new File("storage/sdcard/MyIdea/MyCompositions/" + compoTitle + ".json");
output = new BufferedWriter(new FileWriter(file));
output.write(jsonObject.toString());
output.close();
Toast.makeText(getApplicationContext(), "Composition saved", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
finish();
}
});
Try this write a simple class with static methods to save and retrieve json object in a file :
CODE :
public class RetriveandSaveJSONdatafromfile {
public static String objectToFile(Object object) throws IOException {
String path = Environment.getExternalStorageDirectory() + File.separator + "/AppName/App_cache" + File.separator;
File dir = new File(path);
if (!dir.exists()) {
dir.mkdirs();
}
path += "data";
File data = new File(path);
if (!data.createNewFile()) {
data.delete();
data.createNewFile();
}
ObjectOutputStream objectOutputStream = new ObjectOutputStream(new FileOutputStream(data));
objectOutputStream.writeObject(object);
objectOutputStream.close();
return path;
}
public static Object objectFromFile(String path) throws IOException, ClassNotFoundException {
Object object = null;
File data = new File(path);
if(data.exists()) {
ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream(data));
object = objectInputStream.readObject();
objectInputStream.close();
}
return object;
}
}
To save json in a file use RetriveandSaveJSONdatafromfile.objectToFile(jsonObj) and to fetch data from file use
path = Environment.getExternalStorageDirectory() + File.separator +
"/AppName/App_cache/data" + File.separator;
RetriveandSaveJSONdatafromfile.objectFromFile(path);
Thanks #Chris Handy! I created a JSONObjectVariable and assign it to the makeJSONObject. Here is my final code:
saveCompo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
setName();
createJSONFolder();
CompositionJso compositionJso = new CompositionJso();
JSONObject obj;
obj = compositionJso.makeJSONObject(compoTitle, compoDesc, imgPaths, imageViewPaths);
MyCompositionsListActivity.buildList();
try {
Writer output;
File file = new File("storage/sdcard/MyIdea/MyCompositions/" + compoTitle + ".json");
output = new BufferedWriter(new FileWriter(file));
output.write(obj.toString());
output.close();
Toast.makeText(getApplicationContext(), "Composition saved", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
finish();
}
});
In the method makeJSONObject you instantiate a new JSONObject.
this code should work.
public void makeJSONObject (String title, String desc, ArrayList<String> imgPath, ArrayList<Resources> imgView) {
try {
this.put("title", title);
this.put("desc", desc);
this.put("imgPath", imgPath);
this.put("imgViewPath", imgView);
} catch (JSONException e) {
e.printStackTrace();
}
}

Sending and Receiving messages using Smack Api for Android

I'm trying since last four days to send and receive chat message using own XMPP and with Smack+OpenFire. According to Smack's "readme.txt' i set up the connection and got logged user in. The code of connection and login is this
public static String TAG = "Test connection";
private static XMPPTCPConnection connection;
private static String userName = "demo";
private static String Password = "demo";
static {
// Create the configuration for this new connection
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
configBuilder.setResource("");
configBuilder.setUsernameAndPassword(userName, Password);
configBuilder.setServiceName("192.168.2.10");
configBuilder.setHost("192.168.2.10");
configBuilder.setPort(5222);
configBuilder.setCompressionEnabled(false);
connection = new XMPPTCPConnection(configBuilder.build());
}
This way i configured the connectionbuilder.
here i am connecting and signing in the user.
public class ConnectAndLogin extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... params) {
try {
connection.connect();
Log.i(TAG, "Connected to " + connection.getHost());
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
Log.e(TAG, "Failed to connect to " + connection.getHost());
Log.e(TAG, e.toString());
e.printStackTrace();
}
try {
connection.login(userName, Password);
Log.i(TAG, "Login as a : " + connection.getUser());
setConnection(connection);
setListner();
} catch (XMPPException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (SmackException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (IOException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
}
return null;
}
}
In some tutorials that the addPacketListner must be set after login. i done that in setConnection() and some posts went through addAsyncStanzaListner.
for send message
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Message msg = new Message("demo2", Message.Type.chat);
msg.setBody("Hi how are you");
if (connection != null) {
try {
connection.sendPacket(msg);
Log.d("Send to room : Name : ", "demo2");
Log.d("store", "store data to db");
//DBAdapter.addUserData(new UserData(text, "", "1" ,beam_id));
} catch (Exception e) {
Log.d("ooo", "msg exception" + e.getMessage());
}
}
}
});
and for receiving messages this code
public void setListner() {
connection.addAsyncStanzaListener(new StanzaListener() {
#Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
Message message = (Message) packet;
Log.i(TAG, "REC : " + message.getBody());
Log.i(TAG, "REC: " + message.getFrom());
}
}, new StanzaFilter() {
#Override
public boolean accept(Stanza stanza) {
return false;
}
});
}
here is my dependencies
compile 'org.igniterealtime.smack:smack-android:4.1.0'
compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
compile 'org.igniterealtime.smack:smack-core:4.1.0'

compile 'org.igniterealtime.smack:smack-resolver-minidns:4.1.0'
compile 'org.igniterealtime.smack:smack-sasl-provided:4.1.0'
But still i'm not able to send messages to demo2 user.
Where im doing wrong.Please guide and help me.
Thanks

SignalR for Android: how can I pass dynamic class to SubscriptionHandler1

I have a method startSignalR calling

empty crash file when using ACRA

i am using the code below to generate a crash file, the file is created at parse.com but it is empty.
any idea why?
Another problem is that "ACRA.DEFAULT_REPORT_FIELDS;" has an error, default report fields is not available.
public class LocalSender implements ReportSender {
private final Map<ReportField, String> mMapping = new HashMap<ReportField, String>() ;
private FileOutputStream crashReport = null;
private Context ctx;
public LocalSender(Context ct) {
ctx = ct;
}
public void send(CrashReportData report) throws ReportSenderException {
final Map<String, String> finalReport = remap(report);
ByteArrayOutputStream buf = new ByteArrayOutputStream();
Log.i("hcsh","Report send");
try {
Set set = finalReport.entrySet();
Iterator i = set.iterator();
String tmp;
while (i.hasNext()) {
Map.Entry<String,String> me = (Map.Entry) i.next();
tmp = "[" + me.getKey() + "]=" + me.getValue();
buf.write(tmp.getBytes());
}
ParseFile myFile = new ParseFile("crash.txt", buf.toByteArray());
myFile.save();
ParseObject jobApplication = new ParseObject("AppCrash");
jobApplication.put("MyCrash", "app name");
jobApplication.put("applicantResumeFile", myFile);
try {
jobApplication.save();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}catch (FileNotFoundException e) {
Log.e("TAG", "IO ERROR",e);
}
catch (IOException e) {
Log.e("TAG", "IO ERROR",e);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private Map<String, String> remap(Map<ReportField, String> report) {
ReportField[] fields = ACRA.getConfig().customReportContent();
if (fields.length == 0) {
fields = ACRA.DEFAULT_REPORT_FIELDS;
}
final Map<String, String> finalReport = new HashMap<String, String>(
report.size());
for (ReportField field : fields) {
if (mMapping == null || mMapping.get(field) == null) {
finalReport.put(field.toString(), report.get(field));
} else {
finalReport.put(mMapping.get(field), report.get(field));
}
}
return finalReport;
}
}
There is no such constant as ACRA.DEFAULT_REPORT_FIELDS. You are looking for ACRAConstants.DEFAULT_REPORT_FIELDS
ACRA.DEFAULT_REPORT_FIELDS constant value is in acra-4.3.0 version ...
if you are using acra-4.5.0 version ACRA you will get this error "DEFAULT_REPORT_FIELDS cannot be resolved or is not a field" .
try to use acra-4.5.0 version and then use following code
// Extract the required data out of the crash report.
String reportBody = createCrashReport(report);
/** Extract the required data out of the crash report. */
private String createCrashReport(CrashReportData report) {
// I've extracted only basic information.
// U can add loads more data using the enum ReportField. See below.
StringBuilder body = new StringBuilder();
body.append(
"Device : " + report.getProperty(ReportField.BRAND) + "-"
+ report.getProperty(ReportField.PHONE_MODEL))
.append("\n")
.append("Android Version :"
+ report.getProperty(ReportField.ANDROID_VERSION))
.append("\n")
.append("App Version : "
+ report.getProperty(ReportField.APP_VERSION_CODE))
.append("\n")
.append("STACK TRACE : \n"
+ report.getProperty(ReportField.STACK_TRACE));
return body.toString();
}
Don't use following code
////////////////////////
final String reportBody = buildBody(arg0);
private String buildBody(CrashReportData errorContent) {
ReportField[] fields = ACRA.getConfig().customReportContent();
if (fields.length == 0) {
// fields = ACRA.DEFAULT_MAIL_REPORT_FIELDS;
fields = ACRA.DEFAULT_REPORT_FIELDS;
}
final StringBuilder builder = new StringBuilder();
for (ReportField field : fields) {
builder.append(field.toString()).append("=");
builder.append(errorContent.get(field));
builder.append('\n');
}
return builder.toString();
}
Happy Coding....

How to view the Intents a BroadcastReceiver is receiving?

I have an infinite loop somewhere in my code, indicative of my group messaging BroadcastReceiver continually accepting only the first message in the database, over and over again, until I stop running the application. Note that the repeating of the message only occurs in the client app and not in the server database.
Is there way to trace what intent the BroadcastReceiver is receiving? ie. be able to view the intents the BroadcastReceiver is acting on to locate the source of these actions?
My code for both sending and receiving a group message if it helps: (BroadcastReceiver is near the bottom)
