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?

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'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

I'm writing an Android JUnit test and want to copy/reset a test fixture file (it's an SQLite database file.) If I were within the main application, I know I could just place the file in the assets directory and use getResources().getAssets().open(sourceFile).However, this API appears to be unavailable from the ActivityInstrumentationTestCase2 class.Is there an easy way to copy a file over from the testing PC, or should I just keep a fresh copy of a test fixture on the device and copy it over a temporary file?

I have a project (that compiles and runs in the emulator.) I have a test project that tests part of this project. This test project also compiles with no problems, but when I try to run (test) it in the emulator, I get a NoClassDefFoundError exception on one of the classes my test class tests (I hope that made sense!) when it starts to run in the emulator. This is coming out of the adb log. I looked in the bin directory (of the test project) for the missing class, but could not find it... Should it be there? I found no reference (apk, etc) of the project I am trying to test either in the test projects bin directory. How does the test project get the classes it needs to test against (in the classpath, I assume.) How do the tested classes get moved to the emulator? I did try running the app before testing, so I know it is installed and runs correctly. BTW, I am using netbeans with the nbandroid plugin.

I'm working on an application which allocates lot of memory and hence I'm bound to get OutOfMemory. I want a way to get notified when system is running short of memory so that I can stop processing further, notify user and release as much memory as possible.
According to official Android documentation there is a callback onLowMemory from the system. I have a class which extends android.app.Application and I have overridden onLowMemory() method. This class has entry in the in the application tag of AndroidManifest. However it never gets called in my case. Do I need to register for this event using AndroidManifest or any other means?

Is there any sort of automated test similar to this (The W3C Markup Validation Service) that can perhaps mark how the usability a mobile application is or whether it is secure etc.
Or is the best way to just give my prototype to testers and receive feedback.

I created application with name Test, and has a class that extends broadcastreceiver that listen for PACKAGE_RESTARTED. I use Advanced Task Killer, and killed the Test application. But when I kill another application, for example gmail, the Test's broadcastreceiver got the intent (I logged it). Does it means that broadcastreceiver will never died?

I'm looking for a twitter application for Android that allows a mute function. I know Ubertwitter has it on Blackberry and Brizzly has it for the iPhone. I cannot find anything for android though. I have friends who I like and do not want to unfollow (nor do I want them to know I unfollowed them), but sometime these people go on rants and I would just like to be able to not have to see them when they decide to do it.

When we build and install the test application from eclipse, it is able to launch the test application and show the running of tests. However, we wish to launch the test application from the phone directly. Is this possible. As test application does not have any activity it does not have main icon displayed. Could any one point us to right approach this regards Regards, Raja Nagendra Kumar, C.T.O www.tejasoft.com -Mobile Enterprise Applications Development Excellence

I've always been a fan of V Cast music ID before I recently switched to my Droid X. It was one of my favorite features. I was able to find it in the Verizon apps, as well as Shazam and SoundHound in the Droid Apps. However, both Shazam and Soundhound, no matter how many times I try, say they didn't receive any music or failed to identify a song, and V Cast SongID just stays on the "Listening" screen until I have to close the app. The songs I've tried are relevantly popular songs so I know they're not too unique for the databases. I've placed my phone in every possible way up to my speakers but no such luck. Is this a common problem? Could it be leaning towards a phone issue and not an app issue with three apps all failing to carry out their function. I'm not going to pay for a full version until I get it worked out.

I was trying to send Monkey commands in one of my test applications. But When I install it on the emulator, the packageManager refuses to grant permission "SET_ACTIVITY_WATCHER" which is required to run Monkey.
Is it possible to call Monkey in a test application?

I've implemented an onSaveInstanceState function in the main activity of my TabHost-based application. I need to save the state of various objects I am keeping in memory that I have all marked as serializable, as well as some basic int and string values. I have stepped through my application and watched it call the onSaveInstanceState function and presumably save everything without any manner of exception or problem. The issue is that my onCreate function is being called with a null Bundle value every time after I start the application again. I'm really at a loss and unsure why it would call the save but not pass anything into the create.

I am calling a method of another .apk file dynamically at runtime in my application. I can execute it successfully if method does not contain any variable which is defined outside of that method.
But if I am using the variables which are defined outside that method ( in the same activity or same .apk) then my application throws "java.lang.reflect.InvocationTargetException" at runtime.
For e.g. if method defines as ,

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:
CODE:...........
If it makes any difference the subclass creates a ListView and when a row of the ListView is clicked it calls startActivity();

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?

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:
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 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?
