I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images.

Sep 13, 2010I have 3 days into this and my mind is melting oozing out my ears...
The end result is that I want to upload selected photos from and Android phone to a php website.
I can display the images from the camera and get the filename that I want to upload. However I cannot use FileInputStream on the file name because it is not private to my application. Use FileInputStream generates an error that the file contains a path separater.
Does anyone know how to get the filestream running? Do I have to copy the file into a private file store?
After 3 days of googling this I am amazed I haven't that answer.

Android :: Need To Take Into Account When Repeatedly Calling Same Activity?
Oct 28, 2010I am developing an app where a single activity is instantiated multiple times by itself. I guess you could think of it like a book where each activity is a page. At the end of the page (activity) the user presses a button to go to a new page. I fire off an Intent for the same Activity, but I push different data into the Bundle so that a different page is loaded. This works fine, and I like the fact that the user can back up to a previous point, but my question is whether this will eventually be a problem? What happens if this activity is instantiated 10 times, or 50, or 100? Will the device run out of memory, will GC come along and clean up old activities, or what? If GC does clean them up, what happens when the user presses Back and the previous Activity is no longer on the stack? Is it better to keep track of the user's path, finish() the activity, and override the Back button so that whether the user is moving forward or backwards, I only load a single Activity? Another approach I could take is to refresh all the data on the page so that it's still the same activity, but with new data. The Back button would not work as expected in this case.

Android :: Calling StartActivity From Outside Of An Activity Context
Oct 12, 2010I have implemented a ListView in my Android application.
I bind to this ListView using a custom subclass of the ArrayAdapter class. Inside the overridden ArrayAdapter.getView(...) method, I assign an OnClickListener. In the onClick(View v) method of the OnClickListener, I want to launch a new activity.
I get the exception:
Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
How can I get the context that the ListView (the current Activity) is working under?
Android :: Calling Finish() After Starting A New Activity
Apr 26, 2010The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag?
Is it correct to call finish() after calling startActivity() on the new activity?
CODE:...................
I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?

Android :: Multipart Upload - Transmit The Image Directly From Memory
Oct 12, 2010As part of my Android app, I'd like to upload bitmaps to be remotely stored. I have simple HTTP GET and POST communication working perfectly, but documentation on how to do a multipart POST seems to be as rare as unicorns.
Furthermore, I'd like to transmit the image directly from memory, instead of working with a file. In the example code below, I'm getting a byte array from a file to be used later on with HttpClient and MultipartEntity.
CODE:..............
This all seems fairly clear to me, except that I can't for the life of me find out where to get this ByteArrayPartSource. I have linked to the httpclient and httpmime JAR files, but no dice. I hear that the package structure changed drastically between HttpClient 3.x and 4.x.
Is anyone using this ByteArrayPartSource in Android, and how did they import it?
After digging around in the documentation and scouring the Internet, I came up with something that fit my needs. To make a multipart request such as a form POST, the following code did the trick for me:
CODE:.....
The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important.
Android :: Translucent Activity Not Calling OnStop On Exit
Dec 3, 2009I'm having this strange issue where upon exiting a subactivity that is translucent (android:theme="@android: style/Theme.Translucent" ) the onStop() method doesn't appear to be called. have a TimerTask that runs and is supposed to be terminated when the subactivity ends in the onStop() method, but I'm instead left with an orphaned thread running in the background. It go particularly bad when I ran the subactivity several times. When I revert to no theme, the onStop() method is called and the activity behaves properly. Is there something I missed about how Translucent activities'lifecycles differ from standard activities?

Android :: Free Up Memory By Finishing An Activity After Calling Another?
Feb 25, 2010Hopefully the title wasn't to confusing but what I meant was the following:
Lets say activity A starts activity B by calling:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Could I save/free up some memory by finishing Activity_A after Activity_B is begun (if thats even possible). Maybe through the following:
Intent myIntent = new Intent(Activity_A.this, Activity_B.class);
Activity_A.this.startActivity(myIntent);
Activity_A.finish();
Or would Acitivty_A call startActivity() and wait for Activity_B to finish before it called finish()?
The idea would then be that when the users end with Activity_B, it would just restart Acitivity_A (and finish itself in a similar fashion)? Would this create too much overhead? Thanks for any answers and I apologize if the formatting of this post isn't correct.
Android :: When Does Activity Object Really Get Killed After Calling Finish()
Nov 5, 2010I created a thread in my activity, and that thread will print out the value of my instance variables in my activity after running for about 10 seconds. I pressed the back key to destroy my activity before the thread prints out the values, and when the thread reaches that line of code, it can still print out the values correctly. That means even though the activity is finished, the java object of the activity is still there. Will the object always be there? Or it is just waiting to be GCed? Or it will be killed only when Android needs memory?

Sprint fun has already said I could use the image, but I have no idea how or if its possible to set it as the default image for callers with no photo linked to their account.

Jul 2, 2010I 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(){

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 period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){

System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();

} }
Android :: Can Service Report Back To Calling Activity With Status
Jun 29, 2010Is there a way that a Service can report back to the calling activity when the Service has reached a particular stage of processing? Consider a music player activity that initiates the actual music playing in the background as an Android Service. I want to detect and inform the Activity when the Service has reached the Mediaplayer's onPrepared. Is there a way that the Service can tell the calling Activity when the MediaPlayer's onPrepared is called, to let the Activity know that the audio is prepared and ready to play?I am basically looking to see if there is work around, rather than having a thread in the activity, pinging constantly to check if the Service has reached onPrepared.
