Android :: Droid App Crashes Due To Low Memory / Stop A Thread Before Completion?
Nov 11, 2010My application is basically a image viewer. It is opened from both camera and as a separate application.
I open the image viewer to view and edit the picture. Each edit operation is implemented using thread. If my application closes due to pressing the home button, the next time I open it with camera. It throws anr.
This doesn't always happen. Only when large edit operations or edit operations on large image files are done.
I get out of memory error, sometimes timeout.
I guess it s because the thread doesn't complete the edit operation when home is clicked. and it s still running on the background. so when i open it s unable to process it.
m I right?
If so what is the way to stop a thread before the completion?
Android : Program Crashes When I Call A Class From Another Java File
Oct 26, 2010I am new at android development and java programming, but I have decided to program a drinking game app in android. This app basically simulates a deck a cards, a player clicks a button to draw a card then based on the card thats drawn the player plays a drinking game (ie takes 1 drink, takes 2 drinks ect).
I have the main program in one java file, and the code that shuffles the card deck and puts the card sequence in an array in other java file. My problem is that whenever a class from the other java file (classicMode.java) is called from the main program (fubar.java), my android program crashes and gives the error : "The application Drinking Game - FUBAR (process com.games.dg) has stopped unexpectedly. Please try again". Code...

Android :: Camera In Froyo Emulator Crashes
Jun 28, 2010We are exploring the default applications in Froyo and we found out that the Camera app always crashes seconds after it loads.
Is this related to the no camera/video input limitation of the application? If not, what seems to be the problem? We already added all the additional properties to the AVD. We also disabled the auto-rotate screen option.
Android :: App Crashes In Emulator - Logs Blank
Mar 29, 2010I have a simple app that I am building to get the hang of android's development environment - and things like click events, etc..
The app loads, and I am able to change the text in a textfield using a button handler. However, when I import the location class, and try to do a simple GPS call, the application crashes.
The problem is, everything looks good in Eclipse (error console) - and I'm not seeing any exceptions in the android emulator (DevTools). I have the logcat window open, but I haven't done anything in eclipse/code to send logcat anything (do I need to?)
Is there a better way to troubleshoot?

Android :: Thread Class In SDK LunarLander And JetBoy Examples Not Each In Separate Java File / Why Is So?

Android :: Custom List Cursor Adaptor Crashes At BindView On Emulator - Not On Phone
Aug 23, 2010I will try to be specific if I can - please be patient, first time asker and relatively new to programming on this platform. Apologies if this has been asked/answered before - please link it to me. I have searched up and down but find other unrelated (to me at least) problems.
The real puzzler for me is that my app is crashing on my emulator but when installed on my phone (via upload of apk to phone and then using an AppInstaller app from market) it works.
The crash comes from a NullPointerException at the numbered line in the following code snippet (my code) of a custom list cursor adapter.
CODE:....................
The following error dump is created.
CODE:..............
Curiously I have been happily programming and debugging away all day and out of the blue a long working and bug free portion of my app now throws up this error.
I suspect it might be a problem with the databases, but really not sure - nothing seems out of place there. Up until today I had a database with only one table - today I added a new table which also has a "_id" field as the name autoincrement key field, which I read in the docs was required for android list adapters (if memory serves). Having some experience in coding and some minor experience with databases, that seems like a bad idea to me but I am uncertain of if that is the problem and/or how else to do it.
The crash I am listing here does not display or make reference to the data in the other, new table. The cursor does not contain any query data from it. In fact if I rename the key field "_id" of the new table to something else (ie "_blah"), the crash remains.
Like I said, if I upload the apk to my phone, it works.
I have tried the following on the emulator:
- restarting adb (and eclipse) - no result
- uninstall from emulator - no result
- destory AVD profile and recreate - no result
I am developing this under the Android 2.1 SDK, and have been for the last few weeks. I have only ever had that SDK installed, I am yet to update to 2.2.
Not sure what else I can say here - hoping somebody here has experience enough to shed some light on it.
Without a fix to this, I can anticipate a very slow development process here on out (assuming I have to upload to my phone to test new code changes...).
Android :: Activity Crashes When Remote Service Crashes
Jul 16, 2010I'm trying to understand remote services at the moment and everything works fine, i can start the service and know how to communicate with it through the AIDL-interface. My problem is that the service seems to still run in the same process like the activity it was started from, because the activity crashes too, if there is an error thrown in the Service.
I set the service process to remote ( android:process=":remote" ) so what am i doing wrong? Or what do i have to do to unbind the service-process completely from the activity-process?

Sep 26, 2009I see a strange problem when I try to set a TextView, instead of a layout file via setContentView.
Case 1: i.e. if I do the following, it works fine...
TextView tv = new TextView(this); tv.setText("Hello World"); setContentView(tv);
Everything is OK.
Case 2: But suppose I have a main.xml file with a TextView in it and I try the following:
=========== View tv = findViewById(R.id.textview); setContentView(tv); =========== I get a Force Close with the below error

View 3 Replies View RelatedSetContentView Of Activity Within Activities Current View?
Feb 17, 2012So I have my main activity. It starts out adding a custom SurfaceView called DrawView as the content view with
DrawView drawview = new DrawView(parameters);
this.setContentView(drawview);
now my layout.main.xml is a layout with a video view which I am using to play my cutscenes. I am able to switch to this view by calling a method I made which switches the content view by
this.setContentView(R.layout.main);
which works fine when I am calling this method within the Activity. Only problem is I need to call this method from within DrawView! The method I made to switch to my cutscene is public and I do pass the Activity (named Draw) as a parameter of DrawView.
So when I do call this method from within DrawView my game freezes and will subsequently crash! however it works when method is called locally?

Android : Handle Messages Between The Main Thread(the Deafult UI Related Thread) And The User Created Gamethread
May 21, 2009I 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.

Android :: Communicating Between Receiver Class And An Activity Class
Jul 14, 2010I'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.
