Android :: Pass Complex Objects With Help Of Intents?
Nov 18, 2010I am trying to extend the "android.content.Intent" class by adding a private attribute of a custom class. My goal is to send complex objects from the main Activity to a background Service.
The extension itself is not a problem, the class gets compiled without any errors and the project runs. The only problem is that the BroadcastReceiver does not receive the modified Intent and the "onReceive" method gets never called.
It there any way to pass complex objects with the help of Intents?
Android :: Unable To Get Data From Activity To Service / How Intents Could Pass That?
Nov 24, 2010I am pretty new to this but I was told I could get good help here. A friend and myself are playing around with creating Android apps (using ADT)
Here is how we are trying to make the program: in activity, user sets threshold values for the X and Y axis on accelerometer. When user hits button "Start", startService is invoked and starts TiltService.
TiltService is designed to run in the background always on the phone without user interaction. TiltService constantly compares the threshold with the accelerometer values and will vibrate if they are off.
My problem is I can't seem to get the putExtra() data correctly. I have overridden the onStartCommand in my service but I get the message "unreachable code" when I save the getExtras() to a bundle.
Here is the relevant code (I can post the whole thing, just do not want to clog up page) code...
I thought I understood the basic of how Intents could pass data, but I guess I don't. Is it obvious what I am missing?

Android :: Passing Variable From One Class To Another
Nov 15, 2010I am working to set a countdown timer. I have successfully (borrowed) a number picker (spinner) and set up the dialog box for the user to set the time. This is in a class called timepickactivity and the variables are hour and mins (R.id.hour and R.id.mins). I want to call the set values (R.id.hour and R.id.mins) from the dialog (timepickeractivity) to the actual countdown class (countdown) but I can't figure out how to get the values.
View 4 Replies View RelatedAndroid :: Best Approach For Making One Variable Available In Another Activity / Class?
Jun 22, 2009I have tried to understand for the past 2 days what is the best approach to making the value from a variable sitting in activity A (in my case, the int position used in OnListItemClick / OnItemSelectedListener) available in another activity B (which of course sits in another class). There may be the option to write the result of the OnListItemClick int position into a small SQLite DB - but that seems to be total overkill.
Anybody could pls share the best approach with me?
Android :: Cannot Receive Broadcasts For Package Intents
Oct 20, 2009I am trying to register a Broadcast Receiver to receive broadcast events for the package events. Following is the code and my receiver in the manifest file. The log statment never happens, but I can clearly see the same broadcast firing for "HomeLoaders" (the Launcher) debug statements.
public class IntentListener extends BroadcastReceiver {
@Override public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i("INTENT LISTNER:", intent.getAction()); } }
<receiver android:name="IntentListener" android:enabled="true" android:exported="true">
<intent-filter> <data android:scheme="package"></data>
<action android:name="android.intent.action.PACKAGE_ADDED"></action>
<action android:name="android.intent.action.PACKAGE_ADDED"></action>
<action android:name="android.intent.action.PACKAGE_CHANGED"></action>
</intent-filter> </receiver>
Passing Variable From One Class To Another
Feb 20, 2012I would like to setup a boolean called dFlag in the main.class of my program and reference it in another class.
I already have it setup to work locally just hitting a snag on how to do it.
Code:
public class Main extends Activity {
boolean dFlag; ///Debug flag, true=enabled | false=disabled
}
public class Other extends Activity {
if(dFLag = true) {
///Output debug message
}
}
Or is there an easier way to do what I want without having to re-invent the wheel so to speak?

Android :: Java Reflection - Get All Instance Variable Names Of A Class
Nov 5, 2010I'm writing an android app that requires binding a JSON object into a domain entity with the keys from the JSON as instance variables. Since there are several domain entities, each with different instance variables that the JSON needs to bind to in the app, i'd like to write a method such as ths following: Loop through all the instance variables from the domain if a key exists in the JSON with the name of the instance variable, take the value for this key from the JSON and set the Domain's instance variable with this key name equal to this value. The reason i'm interested in the doing the binding from the class to the JSON is because if the JSON changes for some reason, I don't want it to break the app when the instance variable doesn't exist in the app's domain for a specific JSON key. Code...
View 2 Replies View RelatedAndroid :: Can't Register To Receive Screen Off Intents From Manifest
Aug 24, 2010I have an application that listens for screen off, and user present intents. Since you cant register to receive screen off intents from the manifest, I am registering them in a service. Do I really need to have a whole service to ensure that I always get notified of when the screen shuts off, and the user unlocks the phone? Seems really wasteful :-(
The code I use in my service:
@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "Service created.");
// register receiver that handles user unlock and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_USER_PRESENT);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenReceiver();
registerReceiver(mReceiver, filter);
}

Android : Pass Value From One Class To Another?
Feb 17, 2010Class AddText(extends Activity), Grafitti(extends MapActivity) and MarkerOverlay. Grafitti calls AddText, and AddText opens a new Activity that gets an input from user (EditText), then when that is successful Grafitti calls MarkerOverlay. The problem is I can't access the input in AddText. I need to use that input in MarkerOverlay, I tried creating a setter and getter but it won't work. (error) I've tried searching the web and I think the solution is Bundle. I'm having a hard time understanding how Bundle works. Is there any other way? or any code snippet on how to use Bundle. A code snippet would really help me a lot.

Android :: How To Pass Class Instances Between Applications In Droid
Mar 18, 2010I have an application App1 which defines class A and uses instances of this class. What I want to achieve is - after App1 is installed on the device to be able to load App2 which defines and implements class B which is subclass of class A (imported from App1 package); and be able to get an instance of class B in the App1. Class B doesn't add any new interfaces, so using it as class A is ok. But I am not sure how to pass the instance of class B to App1 (preferrably without any user interaction).
Can anyone advise if this is feasible?
Android :: Accessing Inner Variable From Outer Class Method In Android Activity
Aug 31, 2010I m doing some task with following code,
I want to access inner class variable from outer class method.
class Outer extends Activity
{private Handler mHandler = new Handler();
StopTheThread()
{mHandler.removeCallbacks(mUpdateTimeTask);//
This is the what I want to do:
} class Inner
{ final Runnable mUpdateTask = new = new Runnable() {
public void run() {
//Some Code Goes Here
} };
InnerClassMethod()
{ mHandler.removeCallbacks(mUpdateTimeTask);//
This statement working fine here. Here mUpdateTask is inner class variable which is not accessible from outer class.
Android :: Pass In Object Java Class Embedded In As Parameter
Apr 19, 2010I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?

Android :: Changing Variable Affects Indirect Variable (value Vs Reference)
Sep 26, 2010Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?
