Android :: Inside Service Class / Executing Method For Toast From Scheduled TimerTask
Apr 30, 2010I am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?

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

// 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(){

} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub

Android :: Custom Title Bar With TextView And Id / Title Does Not Inherit
Oct 12, 2010I have a custom title bar that I would like to apply to all my activities. I have searched online and found a few ways of doing that however I have ran into a problem. It seems that despite the fact I have a TextView in my titlebar with id @android:id/title, Android will not use the value defined in the manifest in android:label for each activity. I tried also calling setTitle(R.string.myTitle) but it still will not render it! If I manually put some text in my TextView in the xml it shows up fine. How can I have a custom title bar that is linked and makes Android use my manifest values for labels? I do not want to lose the setTitle() or the XML attributes functionality.

Jul 16, 2010first of all: yes, I read all the other threads on this topic. And not only those from this site...

HTC EVO 4G :: Device Trying Toast's Root Method - Undo Damage
Sep 23, 2010Here's what I've figured out. I tried doing Toast's root method for linux and the directions weren't idiot proof because I screwed them up. I've explained how far I've gotten in other threads. If that's relevant just ask and I'll explain exactly what I did.
Anyway my phone does the basics. It allows me to make phone calls, text, and look at the internet on the phone so this isn't an emergency but it I am worse off than I was before I tried to root because I can no longer use easytether.
I had no problem with easytether prior to the root attempt, and it still works when I hook it up with my wifes untampered evo. with my phone but with my wife's evo, I've never messed with that one, I have no trouble connecting with easy tether.
Some of the things I've noticed about the device since the attmept...
-I can't update to 2.2 via the OTA or any other method, my device says no updates are available.
-Simple root wasn't so simple, the phone never shut off and rebooted into boot screen like the red screen said it would in step 1.
How do I reset the device to the way it was the day it was purchased. I've got everything I need backed up. I'm ready to reset just tell me how.
HTC EVO 4G :: Easiest Method (Fresh / Toast) To Get Rooted Wireless Tether?
Jun 14, 2010I have been reading myself in circles & am a bit confused on which way to go. I am enjoying the Evo but I would like the wireless tether. I guess there are other rooted things in the future I could install but the big draw for me is replacing my wmwifirouter on my WM device on my Evo.
I just don't know what the downsides are for one over other other. I think that Fresh has tethering already built in but I don't know if there are issues with the SD card or other items. Or should I just get the stock ROM that is rooted over at XDA?

Android : When / Where To Invoke Overridden Method Of Super Class?
Apr 14, 2010This question occured to me while programming a Android application, but it seems to be a general programming question more.
The situation is, I am extending (subclass-ing) an class from a library, and overriding a method. how do I know if I should invoke the method of super-class? and when? (in the beginning of the overridden method or in the end?)
For example, I am overriding the method "public boolean onCreateOptionsMenu(Menu menu)" from class "Activity" in Android platform. And I saw someone write "return super.onCreateOptionsMenu(menu)" in the end of the method, in an example. But how do I know it should be done this way? and it is correct or not? what's the difference if I begin my method with "super.onCreateOptionsMenu(menu)"?
Android :: Call Non Static Method (Located In Main Class) From Different One
Oct 18, 2010I've been trying to call a non-static method, located in my main application Class, from the Preferences Class. Because the method I call is not static, I instantiate the main class and then try to call the specific method I want but it's force closing.
Preferences.class (from where I call the method):
Preference sorted = (Preference) findPreference("sortPref");
sorted.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
Object d = new Dmarks();
((Dmarks) d).queryBookmarks();
return true;
}});
the Dmarks.class method I call:
public void queryBookmarks() {
Toast.makeText(context, Toast.LENGTH_LONG).show();
//context is not null and the Toast is working if I call it from Dmarks.class }
The Logcat:

Android :: Sending A String Created Inside A Method To Another Class
Sep 12, 2010I have code which has one activity which passes information to a second activity.
I can use this information to pass to a third activity with additional information from the result of the second activity.
I want to use gestures as a method of going back to a previous activity, but if I go back from the third to the second activity I need the information initially passed from the first to the second activity to still be present.
i.e.
First Acticity
what is Y?
answer y = 5
Second activity
User said Y = 5
what is X?
Third Activity
User said Y = 5
X = 6
Go back to Second activity but maintain the input of
User said Y = 5.
To do this I have used a bundle to pass the information between activities, but I can only access the info in the bundle from within a method within the class started by the intent.
The gesture controls are within another class, so I cannot access the bundle information from within this class as the getIntent command produces a not defined error.
What I need to do is to be able to pass the information from the bundle from the first activity to the gesture class so that I can pass it back when I go back using the gestures.
Android : Override A Method Taking A Reflected Class Argument

General :: How To Hack Webkit Java Class Method
Apr 18, 2012I try to make android java app that uses webkit browser component but in slight different way. My primary goal is to modify the webkit WebViewCore java class method so my android application uses my own WebView which derived from modified WebViewCore and acts as I wish. The problel is that WebViewCore and entire bunch of related classes is not part of public SDK.
So far I tried:
- replaced android.jar from SDK in my project with "full" version (framework.jar)
- copied entire webkit java classes from Android OS to my project and modified the method as I need.
- included in lib/armeabi the libwebcore.so and libchrome_net.so (these I grabbed from rooted phone which I gonna to use for experiments)
- compiled and created apk file with libs included (in the code java layer calls my own libs using System.loadLibrary(..))
- application crashes on launch on device with:
Code:

What should I do for making my own independent version of webkit, so I can install it with my application on specific phone without breaking other apps (browsers) behaviour?
Android :: Style Own Styleable With A Style - Custom View Class With Custom Attribute
Jul 8, 2009I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
