Android :: Core Class Access Resources At The App Layer

Sep 22, 2009

Can a core class such as "AbsListView" access resources, such as xml files, and .png's, in a 3rd party app installed in the normal way (at the app level)?

I realize this is a change in framework code, and that is fine for my purposes. So, for example, if I know that I am going to install an app called "MyApp", could I go into frameworks/base/core/java/android/ widget/AbsListView.java and tell it to use an xml file and .png's that live in that app? Here is the line I would want to modify: setSelector(getResources().getDrawable( com.android.internal.R.drawable.list_selector_background));

Android :: Access Drawable Resources From A Not Context Class?

Nov 7, 2010

So I'm defining a class that sets a Drawable attribute in an object. The problem is that I can't access the getResource().getDrawable(int resourceId) method unless I have some Context.
So what I did was to send to that class an activity instance (let's call it "act") and then I did:

act.getResources().getDrawable(R.drawable.whellchair)

but, when executing that line it throws a NullPointerException.

When idea how to accomplish this?

Android :: Cannot Open Database In Service Layer Class

Sep 15, 2010

When I create a instance of the SQLiteOpenHelper, I always need a "Context" to be passed as its constructor's argument. To use this "Context", in my service layer class, I extends Activity class, though I do not display this activity on the screen because it is my service layer. I always get NullPointer exception when I open the SQLiteOpenHelper in my service layer class, Is it because my service layer class extends the Activity class but I did not show this activity on mobile screen? (That's there is no intent to my service layer class), if it is so, how to get rid of it if I wanna open a SQLiteOpenHelper in my service layer class which do not need to extends Activity, but need a Context object to pass to SQLiteOpenHelper?

Android :: Violation Of Core Library Class Not Existing In Application

Oct 29, 2009

After getting comfy with the Android 2.0 environment and emulator (for the most part), I took the next step to bind <myapp> against the latest Android 2.0 jars: android.jar and maps.jar. The existing code (working in Android 1.6) did not need any changes to compile, but the app doesn't build due to a weird error message that prevents the build. See snippet below, drawn from the Eclipse Console. I have no aspirations to run up against any core library classes, and I am not aware I do. In other words, I am not implementing SealedObject (or any other core class that I am aware of) that would run up against Dalvik. Not in the javax, java or any other namespace. Anybody got any pointers what's going on here?......

public String getStr(){
return str;
}
public void setStr(String s){
str = s;

General :: How To Access Core Android Functions Like App Switching

Jun 28, 2013

Is there any way to access core Android functions like app switching (holding down the Home button for a few seconds), to be used in other contexts? Similar to how you can access Activities from the apps installed and use them as Shortcuts.

What I'd like to do is this:

press Home -> bring up app switching interface
long-press Home -> go to Home screen

Basically I want to reverse the two functions that short and long pressing the Home button does.

If not that, I'm also interested in being able to access the "app switching interface" via a Shortcut (like a Shortcut you place on your Home screen), or via an app.

For example, you can long-press on the Home screen and add a Shortcut (different than adding a shortcut to an App) which basically includes various context functions of some of the apps you have installed. I want to be able to do this - add a Shortcut - in which the Shortcut I add launches the "app switching interface" that you normally get by long-pressing the Home button. That way I can put that Shortcut in Wavelauncher or wherever else I want to be able to app switch without the annoyance of having to long-press something.

Android :: Access Resources From Another Application

Jan 28, 2009

I have created a subclass of Activity, 'CustomActivity', that overrides the onCreateOptionsMenu and onOptionsItemSelected methods. In a couple of other applications I have extended this subclass to provider a common menu for each activity. Is it still possible to access the resources from this Subclass? By default it uses the resources from the current activity (Strings, xml layout etc.).

Sony Ericsson Xperia X10 :: Device With 2.1 / Access More To Its Core

Dec 3, 2010

I have been using Xperia X10i from its launch. It was amazing when it was 1.6. Today it is 2.1 and the access is more to its core. Recently I have installed Z4 Root and ROM Manager. When I click on ROM Manager, it asks to select Phone Model. And in the list I do not find Xperia X10. Can I select any phone model and run the process. Got little scared, as phone might brick.

Besides, I noticed of custom ROM for Xperia X10i (FROYO 2.2)

Can we download and get it rooted as shown in the above link?

Samsung Moment :: Application Layer Of The Phone Is Not Receiving Hardware Layer's Data Correctly

Dec 21, 2009

Ok so I know many are having battery issues. You, like me, probably have more battery life than you think. This is because the application layer of the phone is not receiving the hardware layer's data correctly (hold talk button, end call button, and middle button upon starting up your turned-off phone, this boots in test mode which shows you hardware layer battery power, aka the correct battery life estimate). It's causing another problem because some applications can't be run when the phone THINKS it's about to die.

I have a method in my ItemizedOverlay class which takes an object as a parameter and depending on it's certain values returns an appropriate icon. What's the best way to access the drawable resource from within ItemizedOverlay as you can't access it directly like in an activity?

Android :: WebView-based Browsers Accessing Protected Resources Through Oracle Access Manager -OAM

Oct 5, 2010

We have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.

If we use Mini Opera, we are able to get authenticated and forwarded properly.

This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.

This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

I have created a WebView-based custom browser with the hope of seeing a client-side error and tried trapping every possible error....none show up....

I have tried to trace all of the http requests and found only a single difference in the requests... the http header for Connection:keep- alive is not sent by the Android WebView.

I have provided some tracing info below...

Android :: Access To Class Not Allowed / What To Do?

Feb 6, 2009

I get an apk file from somewhere. I tried to install it the emulator successfully. (The emulator is built from the latest code in AOSP which should be cupcake or later). But I can't launch the application from the GUI. It complains "The application xxx has stopped unexpectedly." After checking the logcat, I find the message "access to class not allowed". It seems that that process is not allowed to instantiate the Activity class.

Since I can install the apk successfully, I am curious why I can't launch it as a user.

BTW, I tried two ways to install the app. 1) by copying it to /system/ app and rebuild the system.img 2) by using "adb install". Both getting the same error message.

I tried to extract the AndroidManifest.xml file from the apk. But it seems that the file is scrambled and can't read.

Android :: Android - Retrieving All Drawable Resources From Resources Object

Jul 11, 2010

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:

InputStream is = Resources.getSystem().openRawResource(resourceId)

However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?

Or, is there a way for me in Java to extract all property values from the R.drawable static class?

Android :: Communicating Between Receiver Class And An Activity Class

Jul 14, 2010

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.
