Android :: Orientation Specific Failure In ListView.layoutChildren - Exception ArrayIndexOutofBoundsException
Sep 20, 2010
I am a very green android developer and need some help with a strange program crash. Often the program will run just fine. There is an equal chance it will fail (see stack at the end). I can watch the program run through the getView function and everything seems in order (i.e. all the information is there as expected and passes through convertView seemingly fine). Either it will go through a few times and then program will be A-OK or it will fail as seen below and I have not been able to pick out what causes the crash. Even stranger is that if I hold the phone in landscape mode, it will never fail!! It only fails about 50% of the time in portrait orientation.

I understand how to force a specific orientation per activity in the android manifest. I would like to know if it is possible to allow the keyboard to change orientation even though the activity(the layout really) must remain unchanged.

I have Activity with ListView inside it and in the onCreate method of the Activity I have code for populating the Data of the ListView this Data is a server based and so populating includes calling Network URLs. I have the ArrayAdapter of the ListView in the Same Activity Class.
Now the Issue I'am facing is that, in Rest all scenarios my Activity is behaving in a proper way but when the Orientation [ Portrait to Landscaped or other way round] is taking place the Data is Getting lost and Newer Data calls are Required to Populate the Same Old Data now this is something that is not intended out the code how should I deal with it.

On a click event I create a thread and start a long-running operation based on this method. After the long-running task is completed, it does a callback to another method, which does a post to the handler:
@Override
public void contentSearchModelChanged(Model_ContentSearch csm, ArrayList<Class_Reminder> newRemindersList) {
remindersList = newRemindersList;
mHandler.post(mUpdateDisplayRunnable);
}...........
This works beautifully when I do this normally. However, if I change the orientation while the long-running operation is running, it doesn't work. It does make the callback properly, and the remindersList does have items in it. But when it gets to this line:
r_adapter.notifyDataSetChanged();
Nothing happens. The odd thing is, if I do another submit and have it run the whole process again (without changing orientation), it actually updates the view twice, once for the previous submit and again for the next. So the view updates once with the results of the first submit, then again with the results of the second submit a second later. So the adapater DID get the data, it just isn't refreshing the view. I know this has something to do with the orientation change, but I can't for the life of me figure out why. can anyone suggest an alternative method of handling threads with orientation changes?

I created a sql lite database with the following columns:
static final String dbName="demoDB";
static final String tableName="Employees";
static final String colID="EmployeeID";
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
db.execSQL("CREATE TABLE "+tableName+" ("+colID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+
colName+" TEXT, "+colAge+" Integer);");
I want to select all the records in the database like this and display them in a gridview:SQLiteDatabase db=this.getWritableDatabase();Cursor cur= db.rawQuery("Select "+colName+", "+colAge+" from "+tableName, new String [] {});String [] from=new String []{DatabaseHelper.colName,DatabaseHelper.colAge};
int [] to=new int [] {R.id.colName,R.id.colAge};
SimpleCursorAdapter sca=new SimpleCursorAdapter(this,R.layout.gridrow,c,from,to);
GridView grid=(GridView)findViewById(R.id.grid);
grid.setAdapter(sca);but i receive the following exception:java.lang.IllegalArgumentException: column '_id' does not exist.the db table does not have a column with name '_id'so what is wrong with this code

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.
Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).
After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?

I have had androids for over two years now and am getting more and more concerned every time I download an app and seeing that it wants to READ my SMS message and Contacts.
Is there a way I can disable reading of SMS messages or any one of the other permissions by specific apps, or all apps?
Are we living in a world where any "joe schmo" can upload an app the to the app store and wait for those inadvertent downloads and collect all your personal information, and that's after all the time we spend protecting our identity and personal details?

I have a problem with working with the ORIENTATION values of the SensorManager. I would like to have some kind of 360°-value which directly shows me if the phone is in normal portrait (0°), landscape, portrait turned around (180°) or anything in between. So I could have, for example, an arrow that points to the floor (like gravity would do with a plummet) all the time, no matter how I tilt (sidewards) the phone. I thought this would be easy, but I'm pretty confused at the moment.
First of all, the X value of the orientation-array seems to correspondent with how I turn the phone, BUT: if it's completely uprightly standing, this value is about 60° ... why not 0° (or 90°, 180°, 270°), as I would expect?
Second: The value resets if I turn the phone and Android automatically changes screen orientation. So both in Portrait and in Landscape mode it will be sth. like 60° when the phone is in a 0° angel in real world. I set "android:screenOrientation" to "landscape" but this doesn't help anything :/
I want the app NOT to change orientation when I turn the phone, but I want it to get a continuous orientation value when I tilt the phone.

I am connecting to a server on my network written in C#. The data sent from the android device is received by the server and a reply is succesfully sent but the android code timesout and never gets the return data.I have tested that the C# server can communicate and reply with a C# client.
I have studied the network traffic using Wireshark when using both the C# server-android client and C# server-C# client and it appears that the android device acknowledges(ACK) the reply data but my code never recieves it.
I have the code running in a thread so running it on Android 4.0 doesn't error out but I have tried running it on Android 2.2 with exactly the same behaviour(or lack of it). Also I have run it on 2 different android devices.
(AndroidManifest.xml)
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

I have downloaded the Layar401.apk file from web and trying to install it into my android device [HTC Magic, OS 2.2]. But every time I'm trying to install it its saying -
adb install Layar401.apk
1098 KB/s (1855698 bytes in 1.649s)
pkg: /data/local/tmp/Layar401.apk
Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY]
From other posts I figured out that there might be a missing shared library of google maps api in manifest.xml file. I tried to view the manifest.xml file and it gave me something like following -
package: name='com.layar' versionCode='27' versionName='4.0.1'

But here it says library includes google maps api as well. So I'm not sure why I'm not able to install this apk file.

I followed instructions from here. After $ repo sync I tried to build it with $ make, but got this error:
CODE:............
Using Ubuntu 10.04 LTS.
UPD: I found a discussion, that claims, that problem could be that I'm having 64bit libs on my 32bit system.
CODE:.....
How do I figure out, if that libz.so.1.2.3.3 is the right lib, and in case I have to replace it with the right one, how do I do it?

I have a similar problem to this question, but slightly different. I have compiled a .so library to use with JNI. Because it is large (15 MB), I am putting it on the SDCard instead of in the standard application place.
The file is called libSample.so and it's located at /data/library/libSample.so
I load it in a static initialization block:
CODE:.............
Here's the relevant logcat output:
CODE:............
I read the post about can android load dll's from sdcard in native mode which said that the sdcard cannot be used to load libraries, so I moved the .so into /data/data/com.example.hellojni/lib/libSample.so (the private app data storage location). No change:
CODE:.............................
What I don't understand is that clearly the library exists, and the OS is trying to load it ... so what would make it fail?
Following the advice of one of the commentors, I tried attaching via strace to get more detailed error information. The log can be found as a github gist.
The error appears to be on lines 47-51:
CODE:...........................
Here's the readelf of the library:

Does the API restrict you from attaching to another database while you have one open?I tried the SQLite3 command "attach database .../contacts.db as aliasdb" .This works in the adb shell and I'm able to perform joins with tables in this database. When I use the same command via the API using "db.execSQL(attach database/contacts.db as aliasdb)" it gives me failure 14.Is this restricted on purpose or am I making a mistake somewhere?

I created a simple client socket from my Activity, but it fails. I am running this activity in emulator and server runs on PC(its a different application without Android stuff).
*clientSock = new Socket("127.0.0.1", 30001);*
logcat shows java.net.SocketException: permission denied <maybe missing INTERNET permission>
If I enable permission for my Activity(android.permission.INTERNET), my Activity constructor itself not called and logcat shows following info. Permission Denial: starting Intent < flg=0x10000000 cmp=com.example.client/.MyClientActivity > from null <pid=-1, uid=-1> requires android.permission.INTERNET.
Any suggestion on how to resolve this issue?

I am working on an app that uses a Socket to connect to a controller over TCP. The protocol library was written in Java and I am implementing it in android via a Service. where the Connection class is a Thread that handles the communications with the controller. It's where the Socket lives.I'm using the Preferences mechanism to store the IP and Port. If I feed the Socket the correct IP and Port, the Connection Service works beautifully. However, I am trying to simulate a user entering the wrong information and having the connection fail. The ultimate goal is to present a dialog and offer the ability to "reconnect" or "update settings". However, when I enter a wrong Port number, the application simply hangs.I was under the impression that Threads executed concurrently so I've tried moving the call to start the Connection Service to a Thread, but it still hangs the application.

I'm trying to write a basic camera app. The problem that I am facing is that it works fine in emulator but on the phone (Nexus one) it fails.
The point of failure is the very first call, i.e. Camera.open(). It fails on the phone saying "Failed to connect to camera service". Any idea what could be wrong? (BTW, I am calling this from my activity's onCreate funtion itself, could that be an issue?)
For the information, I do have the necessary Camera permissions specified in my manifest xml file.
