Android :: Application Subclass Constantly Generates Forceclose

Nov 16, 2010

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 { }

Added this line to the manifest


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

Android :: App.Application Subclass - OnTerminate Is Not Being Called

Mar 19, 2010

From the documentation for

"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's onTerminate() method is never called.

Android :: Test OnLowMemory Function Of Application Subclass?

Jun 11, 2010

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?

Feb 21, 2012

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 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?

Android :: StartActivity From Subclass?

May 15, 2009

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();

Android :: ListActivity Subclass - OnListItemClick Never Called?

Aug 1, 2010

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;............................

Android :: Subclass Of View Constructor Not Being Called

Jun 6, 2010

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?

Android :: Multiple Intents In A ListView Populated Via Subclass

Jun 2, 2010

I 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:


Any ideas why it always opens the view with the same ID even though the TextView "tvCheatTitle" displays a different value in every line?

Android :: Manually Set Preferences Being Overwritten By A Subclass Of PreferenceActivity

Mar 16, 2010

I 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.

Android :: ClassCastException When Casting Custom View Subclass

May 23, 2010

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:



(Theres obviously more, but you get the point)

Now, this is the stacktrace:


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.

Android :: Calling Superclass Method In Subclass Constructor

Apr 30, 2010

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.


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?

Android :: Why Do I Constantly Get ActivityNotFound Exceptions

Aug 9, 2010

I'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 "". No matter what combinations I use, I always get an ActivityNotFoundException. Any ideas as to why?

The code in my only Activity is below....

Android :: Is There Weather App That Doesn't Run Constantly In Background?

Feb 11, 2010

I 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.

Android :: Dolphin Browser Constantly Reloading Pages

Sep 19, 2010

I 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!

Android :: ADT Crashing Constantly - Background Image Related

Aug 12, 2010

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?
