Adding a Icon to notification area in android app

Adding a Icon to notification area in android app - java

O.K i have looked around this site and others and i see something similar to what i am wanting but yet it isn't what i am wanting...let me explain
i am learning to build an android app using eclipse that has a media player linked to my shoutcast server i am running, so far the apps works great but it doesn't have an icon on the top were the notification area is and when i go to a different app (a game) to play while leaving the music playing it minimizes the app .. thats fine but when i reopen the app it doesnt stop the mediaplayer infact if i play the player i will have 2 players running i will then have to force stop it using the task manager,, i know this can be done as i have apps on my phone that has icons and it will do what i am wanting
when i searched this site i found a link to youtube that has soemthing similar to what i am wanting
http://www.youtube.com/watch?v=e74z0_Z5QWI&feature=relmfu the code that is shown is as followed
import android.app.Activity;
public class StatusBar extends Activity implements OnclickListener{
NotificationManager nm;
#Override
Protected void onCreate(bundle savedInstance){
//TODO Auto-generated method Stub
super.oncreate(savedInstaceState);
setContentView(R.layout.statusbar);
Button stat = (Button)findViewById(R.id.bStatusBar);
stat.setOnClickListener(this);
nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
}
public void onClick(View v){
//TODO Auto-generated method Stub
Intent intent = new Intent(this, StatusBar.class);
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
}
i have add this code to my MainActivity.java but it spits several errors to me that i have tried to fix using quickfix here is the script i currently have in my MainActivity.java file

Why the status of text to speech is error rather than successful implementation?

I am trying to make a simple Text to Speech application but it is throwing an error and thus, as a result, the toast is appearing when the button is clicked instead of getting TextToSpeech.SUCCESS as the int status.
Here is the code I used:
package com.example.notifyme;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
EditText txt;
Button b;
String s;
TextToSpeech tts;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt = findViewById(R.id.input);
b = findViewById(R.id.button);
}
public void notify(View view) {//for creating tts activity
tts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
s = txt.getText().toString();
if (status == TextToSpeech.SUCCESS) {
tts.setLanguage(Locale.ENGLISH);
tts.setSpeechRate(1.0f);
tts.speak(s, TextToSpeech.QUEUE_FLUSH, null, null);
Toast.makeText(getApplicationContext(),"Here it is",Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Something unexpected happened", Toast.LENGTH_SHORT).show();
}
}
});
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onPause();
}
}

Thanks in advance for your help

What should i do to move to another activity when only special conditions are met
Basically, an if-statement and an Intent.
Raw code with no variables added:
if(condition(s)){
Intent i = new Intent(this, TargetActivity.class);
//Put arguments into the intent if you need them...
startActivity(i);
}
You can put it in a thread, in an onClickListener, anywhere and any way you want to execute the code.
As to the error you are receiving, I cannot help you with that until you supply the stacktrace from Logcat

You can do like this:
mNextBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (mQuestionCount < questionList.size()){
// set next question
} else {
// call finish
}
}
});

App seems like launching more than once in landscape mode after splash screen?

I have a splash screen and after that my main activity starts. This works fine in portrait mode but if in case i tilt my phone in landscape mode, the main activity can be seen launching more than once after splash screen.
I tried using android:launchMode="singleInstance" but in that case i am not able to attach files in feedback alert-box.

Dont use android:launchMode="singleInstance"
Launch mode you should use "singleTask" for this .
Because singleInstance creates separate task stack for Activity and do not check activity in current Task Stack.
while "singleTask" check each time if an Activity exist in Task Stack it can not create new one.

listView won't populate from bottom

I'm making a chat activity for a school project and I want the newest messages at the bottom of the listView. Adding the code below does not work. I simply want the newest message to appear at the bottom and make the listView automatically scroll to the last list item. Thanks in advance!

Set multiple dialogs in one class and set a textview on one of dialogs

So I'm trying to make two dialogs (dialogInfo & dialogGuide) in one class. One is for showing info about the app, another one for showing the guide how to use it. I can access both of them by click an image button (imbtnInfo & imbtnGuide) respectively on the main class (startover)
Info dialog works fine. But I can't achieve to use textview in Guide dialog so it becomes my problem now. I want to show a text file from /res/raw/legal.txt on Guide dialog (I created the raw folder)
My text file contains html codes too.
Here are my codes:

fileStream.read(fileBuffer);
fileStream.close();

}
catch (IOException e)
{
// exception handling
}
return myText;
}
}

I can't achieve to use textview in Guide dialog so it becomes my
problem now.
So here is your solution:
TextView mtxt1 = (TextView)dialogGuide.findViewById(R.id.textView1);
mtxt1.setText(ImportTextFile());
For reading Text from file:
String ImportTextFile()
{
String myText = "";
try {
InputStream fileStream = getResources().openRawResource(
R.raw.legal);
int fileLen = fileStream.available();
// Read the entire resource into a local byte buffer.
byte[] fileBuffer = new byte[fileLen];
fileStream.read(fileBuffer);
fileStream.close();
displayText = new String(fileBuffer);
} catch (IOException e) {
// exception handling
}
return myText;
}
