I have a webview with a FriendConnect button to allow a user to login to FriendConnect.
When clicking on this button, I'm taken through the expected screens for logging in.
However, it seems like the last redirect after logging in fails with a Javascript error in the browser:

I've gone through the Notepad Tutorials and they are all working on my virtual device. I am now stuck in the midst of trying to write my own Android app.
My setup:
Windows 7 SP 1 64-bit
Eclipse Indigo Service Release 2
Android Development Tools 16.0.1.v201112150204-238534
Android Virtual Device Platform 2.3.3, API Level 10, CPU/ABI ARM (armeabi)
The app is about as simple as they come - you enter a number, it divides it by another number and displays the result.Here is the code involved:
AndroidManifest.xml:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.driving"
android:versionCode="1"
android:versionName="1.0" >

By the time DrivingTimeEstimator's onCreate() method gets executed, the Bundle object (savedInstanceState) is null (which I'm guessing is what leads to mMiles being null, which throws a NullPointerException and kills everything).
I am creating an application which retrieves images from the web. In case the image cannot be retrieved another local image should be used.
While trying to execute the following lines:
CODE:................
The line if(drawable.equals(null)) throws an exception if drawable is null.
Does anyone know how should the value of drawable be checked in order not to throw an exception in case it is null and retrieve the local image (execute drawable = getRandomDrawable())?
I have a very simple Android activity layout like this:

I am following the Parcelable example in the Android developer guide with the intention of having a more complex object that I send to different activities. Right now, my class is a wrapper of a String member. If I put the object in the intent and read it back from the Intent it reads as expected, however, on the receiver side, it is always null-pointer.
View 1 Replies View RelatedI have an activity that implements LocationListener in my application and my onLocationChanged method has been working perfectly up until recently. For some reason the Location object being passed into the method is null. My question is, why is it null? Does it pass in a null object if it cannot acquire a location?
My GPS is on and I have it set to pull a location from the GPS, and I know my GPS can get a fix on me as I used Maps and had it locate me.
Also, I have the permission for my app set as:

I'm trying to open a dialog window, but every time I try to open it it throws this exception:
CODE:.................
I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached it since it seems like I'm missing something:
CODE:............
Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.
I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

View 2 Replies View RelatedWhat is the basic difference between the PhoneWindow and MidWindow policies? I found that the emulator version takes the implementations of the PhoneWindow.When the MidWindow implementations will be used? Also, I found that PhoneWindow handles the call settings implementation and the same is not there in MidWindow? Please someone help me pointing out the differences between both the policies and under which circumstances which one will be used.

View 11 Replies View RelatedI am trying to get a FileInputStream object on an image that the user selects from the picture gallery.
This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

What is "window.demo.clickOnAndroid()"? I know that clickOnAndroid is a method in my Android application. But what is window and demo? My file is called demo.html. Is that it?
I am having issues regarding a LocationListener in my Service called myService.
Here is my code:

locationListener = (LocationListener) new MyLocationListener();
locationManager.requestLocationUpdates(provider, 0, 0, locationListener);

In my Activity there is a button which should stop the service. On the click of the button I am doing:
stopService(new Intent(getApplicationContext(), myService.class).................
Is there an equivalent to Java's null layout in Android? Basically I want to specify the x and y coordinates of each component and not have the layout manager choose where they go. They will be within a scroll pane so it doesn't matter whether they fit on the screen.
I know null layouts are generally not a good idea but I have a special case where I need it. I'm porting a Java TV guide app and the program grid is made up of JLabels. The program dynamically generates them all, setting the x and y coords based on start/end time and channel. Each program could start and end at any time so as far as I know a table layout won't work.
I have a picture in the setImageResource, but I want to make it null; so far I am using i.setImageResource(1), but would like to know a better way.

I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

why RingtoneManager.getRingtone(this, Settings.System.DEFAULT_RINGTONE_URI); always returns null when launching from my activity?
