I've found a example on this site on how to make a subclass of the application for android.
I've created this code
package mensand.test;
class TestApp extends android.app.Application { }
Added this line to the manifest
android:name="mensand.test.TestApp"
And when i run the app it's starts with a force close message.
When i remove the line from the manifest all runs ok

is there an easy way of identifying which application generates spam messages that appear in the notifications?
sometimes the icon gives it away but not all the time..
From the documentation for android.app.Application:
"Base class for those who need to maintain global application state"
I am using my own subclass to maintain an object that I'm using to query a server. Also from the documentation:
"onTerminate() Called when the application is stopping."
However, onTerminate() in my class is never called. I press the back button while viewing my main activity, and everything seems to shut down. My main Activity's onDestroy() method is called and isFinishing() returns true, but my android.app.Application's onTerminate() method is never called.
I have put some instructions in onLowMemory() callback and want to test the same. Is there a "direct" way to test onLowMemory function of the application subclass?
Or will I have to just overload the phone by starting many apps and doing memory intensive tasks?
I'm rooted and I have a lot of app updates, but I'm getting constant fcs from the app market to update. Is it a root issue or a google/android issue ? I got a droid by the way.

Hi,
Is there any api on android which generates a Thumbnail image from an inputstream which is a video file?
Thank you.
I am using Eclipse and trying to run one of the examples. However, when I do, it generates many errors.
I am trying to test using the AlarmController.java file. Do I need to create a project with all the same names and classes within this java file? Or is there a project already created somewhere in the SDK I should be trying to run?
I have a Activity and I have a class which extends this Activity. In this subclass I call:
startActivity(new Intent(this, CameraView.class))
Which should start the "CameraView" Activity. However, I always get this error:

If it makes any difference the subclass creates a ListView and when a row of the ListView is clicked it calls startActivity();
I have one subclass which extends Dialog class, it seems I can not use startActivity() function to start a new Activity in this subclass which extends Dialog class, how to resolve it?
How to start a new Activity in a Dialog subclass? (In my customized dialog subclass, I have one button, when pressed, I would like to have a new Activity start).
I have subclassed ArrayAdapter to set the color of text to RED if the string does not contain 100%, this has been added to a ListView. The problem is that some of the rows show as red when they contain 100%.
CODE:.....................
I don't think this problem is caused from my ListActivity subclass. I think it has something to do with with my BaseAdapter subclass:
package com.mohit.gtodo;
import com.mohit.gtodo.database.TasksDBAdapter;
import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CursorAdapter;
import android.widget.TextView;............................
I'm subclassing Android's view class, but whenever I make an instance of the view from another class, the constructor never gets called (or so it seems). I've implemented both public myclass (Context context) and public myclass (Context context, AttributeSet, attrs) I can't figure out what I'm doing wrong. Do I need to override onDraw and onMeasure?
View 1 Replies View RelatedI have a ListActivity which is being filled via an internal class "OrderAdapter" - while the list is being populated I set various OnClickListeners on the TextView elements which should open the same view with different parameter values per line. My problem I have is that no matter which entry in the list I click I will always get to a view with the same parameter ID (it's always the ID of the last line in the list) - even though the output of the ID varies if I output it to the TextView.
Here is the code of the internal class which populates the list in the ListActivity:
CODE:.............
Any ideas why it always opens the view with the same ID even though the TextView "tvCheatTitle" displays a different value in every line?
I'm implementing custom widget exdending a View class. But I've found that View's protected field (e.g. mLeft) is not accessible from subClass
View 2 Replies View RelatedI am having a problem with an application I am in the middle of writing which is causing me some serious headaches.
The situation is this:
The application allows the user to configure several different kinds of information in several activities.
One of the activities, which is a subclass of Activity, takes data from the user and stores it in a shared preferences instance that I create manually and edit in code. This activity requires a complex screen layout that I do not believe would work well with a PreferenceActivity, hence me rolling my own in this case.
Another one of the activities, which is a subclass of PreferenceActivity, is a straight forward list of preferences, each with a list options - standard stuff.
I am finding that any data that I store from the first activity, my bespoke preference screen which manually adds the data using a StoredPreferences.Editor instance is overwritten once the user selects an option in my activity that extends PreferenceActivity.
I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency).
So what i got is this:
main.xml:
CODE:..........
(Theres obviously more, but you get the point)
Now, this is the stacktrace:
CODE:...........
Why cant i cast my custom view? I need it to be that type since it has a few extra methods in it that i want to access. Should i restructure it and have another class handle the logic, and then just having the view being a view? I'd really like this to work though.
I get a NullPointerException calling a Superclass Method in Subclass Inner Class Constructor... What's the Deal?
In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class.
CODE:...................
After I instantiate the object in the constructor, I get a runtime error when I try to assign a value in the inner class with a superclass method.
Can you not call superclass methods in the subclass constructor?
Do static variables of an ApplicationContext subclass left untouched when the process is killed?

View 4 Replies View RelatedAll of a sudden, in my notifications area, there is something that is almost always "synchronizing my contacts". This just all of a sudden appeared. I didn't download any app for this, and my contacts don't even appear in gmail.Anyone know what is doing this? I'm always worried about what apps send all my info out. Something seems fishy. The icon that appears on the top left is gray and spins.
View 5 Replies View RelatedI'm a novice Android programmer, and to help me understand how Intents really work, I wanted to put together a small Activity which would let the user call startActivity() with any action and data they want. I tried many different combinations, including "android.intent.action.VIEW" and "http://www.google.com". No matter what combinations I use, I always get an ActivityNotFoundException. Any ideas as to why?

View 3 Replies View RelatedI really like the Weather Channel App and Weatherbug, but they both constantly start themselves and run in the background no matter what my settings are.I don't need my phone to update weather in the background as I don't check it that often.I just want something that I can open, check the weather and CLOSE really close.Is there a decent Weather App that will let me close it and not run on its own?Seems to me that its a common problem with apps, that many devs don't properly shut them down or force them to run unnecessarily.

View 7 Replies View RelatedI have a rooted Droid X running the original 2.2 leak and have been using Dolphin Browser HD since I got it. Lately I noticed every time I go back to the browser after "minimizing" it, it reloads the pages that were open. Now, I could be completely crazy and it could have been doing this the entire time I've used it but I feel like this is something new. It's quite annoying actually, as I have to wait every time I pull the browser back up. I can't point at anything that recently changed that could have affected it, I even uninstalled and reinstalled it to try and fix it but to no avail.
Am I the only one this happens to? Am I crazy and it has been happening the whole time and I only just noticed it? When is the droid x 2.2 official OTA coming out!
I don't know if this is the right group, but my ADT keeps crashing while editing layout files. I'm not positive, but I think it might have something to do with the background images that I'm attempting to use, as they are not rendered in the preview at all. Is this the appropriate group to discuss the ADT tools? If so, does anyone else have problems getting background images to display?
View 4 Replies View RelatedJust my a new Android phone and I've been tinkering with some basic apps. It's been driving my crazy that the Android plugin for Eclipse refreshes externals folders whenever I save ANYTHING. Normally I wouldn't mind but when it takes 10s to refresh I start to notice. I already searched and other people have this problem, but there are no solutions. If it matters, Eclipse 3.5 running on a 64bit jvm on Ubuntu 9.10
View 2 Replies View RelatedI have updated all my apps earlier today and ever since there has been 6 or 7 apps that are constantly showing the status of installing in the android market. I have had to charge the battery twice today because of this. Is there anyway that I can stop these installs? I am new to android so please be gentle. I have a samsung galaxy s and so far have tried uninstalling the apps it says are installing, clearing the cache, force closing the market, switching phone off and also performing a battery pull.
