Android :: Calling Method From Service Immediately
Sep 3, 2010I'm pretty sure that android services are going to be the end of me.I have almost no hair left after the last few days.At first I was having a heck of a time getting the service to bind on an onclick of a button, got that straightened out from help here yesterday. Now I actually want the service to bind in the onCreate() method of the activity. That part is no problem, works as intended.My service is actually a socket service to connect TCP sockets to a socket server that I wrote.If I put the call to the method from the bound service mBoundService.StartSocketServer() inside a button click, bingo, works great. But I need this to fire up immediately when the activity loads, so directly under my bindService() call within my onCreate() method of the activity.When I place the call to start the socket inside my onCreate() I get a force-close.
This method (StartSocketServer()) spawns a new thread then opens the socket on that thread to my remote machine.I'm guessing that the problem lies with the new thread generation before the activity fully loads not sure.LogCat is fairly cryptic here. It does say something about thread attach failed, then shows an uncaught handler exception that has "Caused by: java.lang.NullPointerException" within it.Again, if I put this call to the method inside a button click, I"m in business, if it's in the onCreate() it fails. Is there some way inside an activity (presuming that my assumption is correct that it needs to fully load before spawning a new thread) to call the StartSocketServer() after it's loaded: ala body.onLoad() in html?
Android :: Calling A Non-static Java Method From C
Dec 22, 2009In my Android app, I need to call a non static java method from C/C++. But i get a blunt crash when i do it using GetMethodID/CallVoidMethod()1 methods.
I have done like this:
1. Register the method using GetMethodID() as follows (mine is a cpp file): jmethodID xyz = (env)->GetMethodID( cls, "showxyz", "()V");
2. And I call this method as follows: env->CallVoidMethod(cls, xyz);
3. In java, my showxyz() is defined this way(this basically enables a button which was disabled) void showxyz() {findViewById(R.id.btnPass).setEnabled(true);}
And this crashes.
But I have been using this method of calling Java funcs from C using a set of GetStaticMethodID/CallStaticVoidMethod()(for nonstatic methods) and that works always.
But in this case, I have to call a non-static method and i get a crash.

Android :: How To Stop Service Method Of Calling Activity Class?
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(){
@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);
} }

Intent i = new Intent(Intent.ACTION_CALL);
// cursor of the selection Cursor c = (Cursor) mAdapter.getItem(position);
// get some info from the cursor
String contactId = c.getString(c.getColumnIndex(Contacts._ID));
String IsPhone = c.getString(c.getColumnIndex(Contacts.HAS_PHONE_NUMBER));
//if the selection has phone numbers if (Integer.parseInt(IsPhone)> 0) {
Cursor phones = getContentResolver().query(Phone.CONTENT_URI, null, Phone.CONTACT_ID + "=" + contactId, null, null);
while (phones.moveToNext()) { String strPhoneNumber = phones.getString(phones.getColumnIndex(Phone.NUMBER)); System.out.println(strPhoneNumber);

Android : App Crashes - Can't Find A Java Method Despite - No Compiler Error
Aug 20, 2010My Android app runs fine, but: If I insert a call to WebView.setScrollbarFadingEnabled, it crashes saying:
Could not find method android.webkit.WebView.setScrollbarFadingEnabled, referenced from [my class]
VFY: unable to resolve virtual method 289: Landroid/webkit/WebView;.setScrollbarFadingEnabled (Z)V
I am using Android 1.5, not a custom ROM. My app defines minSdkVersion="3" I always clean before compiling.
Is setScrollbarFadingEnabled unavailable in Android 1.5? If so, why don't I receive a compiler error?

Android :: Phantom Error - Error Parsing XML - Unbound Prefix
May 26, 2010The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check).
My environment is:
Fedora Eclipse Platform
Version: 3.4.2
Based on build id: 20090211-1700
My target is Android API level 5.
The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error.
