I have a SMSReceiver class that needs to pass the phone number and message to another class. Which works but when I call that class I need the function to read preference to compare if it needs to execute another function.

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

View 3 Replies View RelatedI see calling the stop function of MediaPlayer simply does nothing. The playback goes on.
I looked in the documentation and I found: "Stops playback after playback has been stopped or paused."
So, I tried to pause() it before stopping, but the MediaPlayer then pauses and resumes the playback. The only thing I can see is that the buffering stops. But the playback continues. Is this the expected behavior? Could the problem be related to the fact that I call the methods of the MediaPlayer object from different threads than the creator by synchronizing with Semaphores?
I know that when a row is selected in list view, the function on List Item Click() is called. I want to know which function is called when a row in List View is highlighted(not selected).

I came over from BlackBerry, where there is simply an option to "hide" my phone number on outgoing calls... but I can't seem to do this with my Eris. Someone once suggested that I prefix my contacts with *69... but that seems to prevent caller id from working properly, which just trades one issue for another.
If possible, I would prefer to be selective with who I do this with (it's okay for personal contacts to see my number... but it's not okay for business contacts to see my number).
How can I detect whether or not an Image View has a picture in it upon a button click. I had a class that displays a picture and some results, but I don't want the user to be able to access those results (pushing the button) until the results have been written to that class.
So, I figured I needed to check to see if there was a picture displayed in the ImageView yet.
So something like:
CODE:...............
But obviouslt R.id.photoResultView == null isn't the right way to do it...anyone know how?

I have two classes, one MainClass and one DataBaseHelper class, which extends SQLiteOpenHelper.
From my MainClass I call a method in the DataBaseHelper class to open a data base. Before opening the data base I want to check the users data base version (this is important as soon as I want to update the data base and push it to the Android market). So from the DataBaseHelper class I call the following method, which is in the MainClass.

I call the checkCurrentDbVersion() method from the DataBaseHelper class like so:

I am calling intents alot in my program and I thought that I could write a public class that would have all of my intents so I can just call something like intents.testIntent(params) and then have it fire off the intent.
I tried it out but am getting a force close with a null pointer exception. This is my whole class. I know it is probably sloppy but I have just been learning java for 2 months so I still am an amateur. Any way, my code...
I am calling a method of another .apk file dynamically at runtime in my application. I can execute it successfully if method does not contain any variable which is defined outside of that method.
But if I am using the variables which are defined outside that method ( in the same activity or same .apk) then my application throws "java.lang.reflect.InvocationTargetException" at runtime.
For e.g. if method defines as ,

I release a class. In the class, there are public fields that can be written. I want to register the callback function which will be called right after my field is accessed. I think I can do that by using JVM tool interface which is supposed to be used for a debugger software. JVM tool interface:
I'm not sure same interface is working on android. or, They provide another form of interface to get a notification of a field access.
I am trying to call my service class's stopService() method from my activity. But I don't know how to access stopservice method from my activity class. I have the below code but its not working. This is HomeScreen class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
} else {
stopService(new Intent(HomeScreen.this, AutoService.class));
} } });
}
This is Service Class:
public class AutoService extends Service {
private static final String TAG = "AutoService";
private Timer timer;
private TimerTask task;
@Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "Auto Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
int delay = 5000; // delay for 5 sec.
int period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){
public void run() {
System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();
return super.stopService(name);
} }

My point is to be able to call a 2.1 API if it exists, while the application should be able to run in 1.5
Specifically, I am making a GPS application which would like to call android.location.LocationManager.addNmeaListener if available. My problem is that this call takes as parameter an abstract class (GpsStatus.NmeaListener) which I cannot pass directly to Class.GetMethod (or my application won't work in 1.5). What I am currently trying is a) to create a wrapper class for GpsStatus.NmeaListener:......................
I'm trying to write a simple application that attempts to receive SMS messages and handle them. I've followed several tutorials but I'm getting nowhere, when I send a SMS to the emulator, the Intent never seems to get fired.I'd really appreciate some guidance with what's going wrong. I'm just getting into Android development but I think I have my head wrapped around (most of) it. While monitoring the emulator's logcat, the log events never come up, and debugging breakpoints are never hit, so I have a feeling it's somewhere in my intent filter.

View 2 Replies View RelatedWhen using G Maps, it says Waiting for Location almost indefinitely.I reinstalled the G Maps updates.Then I downloaded GPS Status to see if a different app could use the receiver and it had similar problems. After 20 minutes or so, it got a lock onto the satellites but not only did it display our location as several hundred feet off, it didn't track our movements while we were in the car going 60 mph.Apparently, it got a lock, but only momentarily or with very poor reception.So I have all of the typical forum questions.
1) Has this been reported before for the D2?
2) Is there anything I can do fix this before doing a hard reset?
I have an ArrayAdapter (myAdapter) attached to an AutoCompleteTextView (textView)component. Once the user presses a character I would like to populate AutoCompleteTextView's drop down list with items containing this character. I retrieve the items using AsyncTask (which uses a web service).
I call myAdapter.add(item) but the drop down list is empty.I added a call myAdapter.getCount() after each addition and it shows zero every time.
Calling notifyDataSetChanged() didn't help.I even tried to add simple String objects instead of my custom objects, to no avail.What am I doing wrong?
Edit: I changed the code as miette suggested below but still to no avail.
Generally, what I do is after text is changed in my auto complete text view, I call a new AsyncTask and pass it the entered text and a Handler (see afterTextChanged()). The task retrieves objects relevant to the text and once done the Handler's handleMessage() is called. In handleMessage() I attempt to populate the adapter's objects. But still the adapter's drop down list ends up empty.
Here is my code:
public class AddStockView extends Activity implements OnClickListener, OnItemClickListener, TextWatcher {
ArrayAdapter<Stock> adapter;
AutoCompleteTextView textView;
Vector<Stock> stocks;
public AddStockView() {
// TODO Auto-generated constructor stub
stocks = new Vector<Stock>();}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.add_stock_view);
findViewById(R.id.abort_button).setOnClickListener(this);
adapter = new ArrayAdapter<Stock>(this,
android.R.layout.simple_dropdown_item_1line, stocks);
//adapter.setNotifyOnChange(true);
textView = (AutoCompleteTextView)
findViewById(R.id.search_edit_text);
textView.setAdapter(adapter);
textView.setOnItemClickListener(this);
textView.addTextChangedListener(this);} Code...
I try to learn java for android devices. i have to create the update function. But still have one question: How?
in class root
public void update(){maindebug("update"); // This is my debug function}
public void run(){ while(isRunning){ // isRunning is a boolean variable
SystemClock.sleep(100);
update();}}
and inside onCreate run(); but it doesnt work.
I must be overlooking something because I am unable to get my TabHost to display in my Activity class.I am getting the dreaded force close when I try to run the app.It will work if I extend TabActivity, but I can't do that [details at the bottom] because once I move the code from my prototype project its going to be in a custom class that inherits from Activity.

View 2 Replies View RelatedHaving a problem when I'm setting my phone to the vibrate function. It doesn't vibrate at all, just acts as if I set the phone to silent.
How do I fix this? Anyone else have this issue since the rogers update. My gf is having the same problem with her X10.
I have an original Nexus 7 running Android 4.3. I just learned about the "Take bug report" and "Power menu bug report" method to capture screen shots and logs. Unfortunately, they don't seem to work for me.
I'm logged on with my normal Google account. When I use either method, I get the "Take bug report" popup. When I tap on Report, the popup goes away and then nothing happens - no email - nothing. I've seen a couple of other reports of this happening.

My auto focus has been really inconsistent recently, some days it will work for a little but for the most part it doesn't focus anymore. I've also been having a lot of issues with the headphone jack, what should I do? btw, my insurance on my phone is protectcell. Do you think they would consider upgrading me to a Droid 2 or a better phone? (my phones rooted, I changed roms to see if that was the issue, but the problem still occurs)

View 3 Replies View RelatedHad a few days of use without issues, go to make a call yesterday and it takes ages to connect, but instead of connecting I get a beep and then it returns me to my contact list. Tried putting the phone in and out of flight mode by holding down the power button and selecting the flight mode option, the option turns grey after I press it, won't allow me to press it again and seemingly does nothing. Press the off option and turn the phone back on and it's fine. Now I reckon I had suffered this with earlier firmwares.
