How can I implement a run() method of thread if I create a Thread Global?
I mean If I create a Thread Globally then can I implement its run() method {" public void run()"} anywhere in my Application?
In the run() method I have to write the code to perform some action.
IF I can do it then please can anyone show me briefly how to do it particularly.
I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged(). But it does not work. Any workaround for that?

I was told to do this but don't quite understand why that would speed things up. Is it GameView that should implement Runnable? Should I make the thread sleep when not drawing? where should I start the thread? package com.android.WWS;

I need to suspend/resume a thread from another thread in the same process. I tried to look into thread apis,but I couldn't figured out a way to achieve this.Can anyone pls point me some references to look or give a tip to do this.

View 1 Replies View RelatedI've installed the newest Android SDK using eclipse's software updates feature to hit the resource at https://dl-ssl.google.com/android/eclipse/.
After installing it, it seems like the SDK is integrated into Eclipse, but when I try to create a new project with a single blank activity in it, I get the following error:
CODE:.................
This is using eclipse version 3.4.2 running on top of Mac OS 10.5.7 on a 32 bit processor.
Is this a misconfiguration on my part? Have I missed a part of the installation?

View 9 Replies View RelatedI've had the E Strong File Explorer for some time but never really used it. So today I wanted to create a special folder for some pictures i downloaded off the web. All the ones I downloaded were put under sdcard/downloads. I created a folder and named it "Cars" and then went to the download folder, copied the pictures, went to the Cars folder and pasted them there. I then think I made a mistake and went to the original pictures in the download folder and deleted them. Now when I open my photo gallery and go to the download folder, i see frames for the pics but no picture. And when I try and open them I just get a black screen. When I go back in the file explorer, I'm able to go to the "cars" folder, click on a picture, choose image from the drop down menu, and then I can view it. So what did I do wrong and is it fixable?
View 9 Replies View RelatedMy android app was running ok under Eclipse, then I tried to add some GridView sample code from some online examples and now it will not build/run anymore.
I keep getting the major error:
CODE:..
Attempt to include a core VM class in something other than a core library.
I have never put anything to do with 'SocketFactory' in any of my code. I searched all of my code and can't find any code that I did that contains the SocketFactory.class.
I deleted my xml's and classes that I was working on that had to do with the GridView and reverted back to the code I had before, when it was running - but now I continue to get the above error. I even try to use 'Clean' but the error continues. Does anyone know what I should do about this error?
I'm new to android. I'm using webview in scrollview to display my local html page (html has text only). I created two buttons for zoomin and zoomout using behind function zoomIn() & zoomOut() respectively. These functions work fine. The problenm is, when I zoom in, some of the text goes out from both top and bottom and it doesn't appear when I scroll.

View 7 Replies View RelatedI've had more than one user say they have trouble when they "upgrade" new versions of my app in Android Market. One woman says it takes her several "days" to successfully do it (I presume that means multiple attempts spread out over time).Can this be on my end? I upgrade my database on each rev - basically I retreive the user data and stick it in the new database that ships with my app. But I think the complaint is about something different. Has anyone else received comments about anything similar? I am concerned people uninstall my app just because of this issue,

View 2 Replies View RelatedI have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app.
From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity.

View 1 Replies View RelatedI'm happily retrieving contact photos with the new Contacts Contract APIs and cursor.getBlob, but I'm having great trouble working out how to set a contact photo.
I believe I have the right URI (at least, it works for retrieving the photo), but it just won't work for updating or adding one.
Here's my best bet:
ByteArrayOutputStream bytes = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
Uri uri = Uri.withAppendedPath( ContactsContract.Contacts.CONTENT_URI, friendId ); uri = Uri.withAppendedPath( uri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
// eg: content://com.android.contacts/contacts/6/photo
ContentValues values = new ContentValues();
values.put(ContactsContract.CommonDataKinds.Photo.PHOTO, bytes.toByteArray()); values.put(ContactsContract.CommonDataKinds.Photo.MIMETYPE, ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE );
context.getContentResolver().insert(uri, values);
And here's my exception:
java.lang.UnsupportedOperationException: Unknown uri: content://com.android.contacts/contacts/6/photo at com.android.providers.contacts.LegacyApiSupport.update (LegacyApiSupport.java:914) at com.android.providers.contacts.ContactsProvider2.updateInTransaction (ContactsProvider2.java:2924) at com.android.providers.contacts.SQLiteContentProvider.update (SQLiteContentProvider.java:139) at com.android.providers.contacts.ContactsProvider2.update (ContactsProvider2.java:1923) at android.content.ContentProvider$Transport.update (ContentProvider.java:180) at android.content.ContentProviderNative.onTransact (ContentProviderNative.java:195) at android.os.Binder.execTransact(Binder.java:287) at dalvik.system.NativeStart.run(Native Method).

View 1 Replies View RelatedI am working on an application that requires an approximate position of the user, so basically i am fine with any relatively recent location data i can get. However I can't seem to get things right using mock location data and would therefore appreciate your help. The method i'm having tries to set mock location data for the gps provider and tries to later retrievie it BUT: locationManager.setTestProviderEnabled("gps", true); seems to fail because i do not get any active location provider from the location manager. When I tried using a mock location provider with addTestProvider and give it my mock location, the LocationManager returns me this mock provider with getProviders(true) but then getLastKnownLocation returns null instead of the provided mock location.
