Android :: AudioManager Declaration Crashes App
Oct 16, 2010
I'm having a bit of trouble with an Android app that I'm working on (mostly for practice and learning purposes) that uses the AudioManager object.
When defining the AudioManager as follows, however, the app crashes when I run it:
CODE:................
When I simply comment out the AudioManager declaration, the app does not crash. Any ideas as far as what I'm doing wrong? I'm a bit of a beginner to Android development, so I have a feeling that I'm missing something obvious.
I've also tried adding the android.permission.MODIFY_AUDIO_SETTINGS and android.permission.MODIFY_PHONE_STATE permissions to the AndroidManifest.xml file, but that has made no difference.

I want to create an android Layout of which I want to instantiate several copies. I understand that declaring the layout in an XML will create a single instance. Is there a way to use the XML View declaration as a 'definition' rather than a 'declaration' ? Or is it possible to clone a view?

I accidentally imported a resource file with a capital letter in the name (SDK 8) and as we all know, that corrupts the R.java file in a way that rebuilding the project doesn't fix (I renamed the file to something legal from within Eclipse, of course). So now the build chokes with the error above when it hits the first xml file in res. In SDK 7 the only fix was to build a fresh project and move everything over. I'm hoping there is something better in SDK 8.

We are planning on using setParameter() function in AudioManager.java for turning on/off some audio effects from the UI. This function goes all the way to the HAL layer. However, we see a comment in the code saying the following (pasted at the end of mail). So, my question is it okay to start using this API with our own defined set of (key,value) or is there a possibility of this function disappearing later. If yes, then is there any other recommended function to pass on UI settings all the way down to the HAL.

We just released our first widget to the market called AudioManager, it's available now and free to download to anyone who has cupcake already installed.AudioManager is a home-screen Widget that allows you to get live readings of your current volume levels on your Android phone (similar to your computer's "Volume Mixer").Tap on the screen and you can adjust the volume levels individually for the following streams: Alarm, music, notifications, ringer, system and voice call volume.The widget comes in two sizes, large (4x1) and small (2x1). The AudioManager Console is also available through your application launchpad in case you do not need the Widget on your screen but wish to access all volume streams from one place.Attached are a few screenshots, check it out and let us know. Only tested with Android's default home-screen, however, there are mixed reports of the widget working for aHome and dxTop with the latest versions.

I'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?

I can't seem to change alerts and ringer volume seperately using Audiomanager pro. Whilst at work i want to hear my txt message sounds (alerts) but not my ringtone, and i want the phone to vibrate with both still. However when moving the ringtone and/or alert slider the other one moves too, they can't seem to move seperately. Am i doing something wrong or does this app not do that, and if so, is there an ap that does?

Just wondering, on 1.5, the Ringer/Alerts volume was locked together so however loud the Ringer volume was, the notification volume would be the same. Since upgrading to 2.1 OTA, they are no longer linked together. Is there any way I can link them back together so they are they same volume without having to individually change each one? It's kind of annoying when I set my Ringer volume to low, and all of the sudden I get a text and it's almost 3 times as loud.

I've been using:
Notification.DEFAULT_SOUND
for quite some time with great success. When I replace that with:
Notification.DEFAULT_ALL
the program crashes when the notification is called.

I'm trying to create an application that has 3 tabs. Under the middle tab should be a ListView. It starts up fine (on the left tab) but when I click the middle tab it crashes.
The other two tabs are static data specified in the main.xml file. But the middle tab, I try to create dynamically. Here's the code from the main onCreate function:
CODE:...............
Instead I appear to get an exception:
CODE:...............
ContactListActivity is defined this way:
public class ContactListActivity extends ListActivity { ...
I get the feeling that I'm supposed to create the Intent with something like Intent.ACTION_VIEW but this is where I get lost. If this is the problem, I could try stuff until it works, but I'd prefer to understand why.
Or is ContactListActivity supposed to override something ?

I'm getting fairly regular crashes using WebView's in the underlying C code (sigsegv's). There isn't a _whole_ lot of rhyme or reason to it, but one thing that is somewhat suspicious is that I have more than one webview active (only one is one the screen at any one time, but if this has anything to do with my problem it may not matter since it appears that webkit widgets run asynchronously from the main UI thread).
Here's the stack dump. I've looked through the archives and it appears that there are other dumps, but it's really hard to tell from my vantagepoint whether they have anything to do with one another.
This is pretty easily reproducible (especially with one particular url of mine) so it should be relatively easy to track down.

I have separated java code from Android code and have two projects. Android dependent on Java project. Now i want to get the memory trace of the Java project on Android. For that I have created Androd Junit Project implementing Android Instrumentation, and a dummy android project dependent on my actual java project.(as I only want to get memory trace of java project on android).Problem is when I execute Android Junit project, and give a reference of dummy project removing java project dependency, all tests(dummy) run fine.But when I run junit project, with dummy android proj keeping dependency on java project, my application crashes.I get an error message like : "Process crash" not getting any error message in logcat. No clue whats wrong with code.Any help is highly needed.

In my application I've implemented such that pressing the hardware volume keys displays a Toast with the current volume. Things go well most of the times. However long presses of the volume keys do succeed in crashing my application. The Log generated on crash is the following...
The approach I follow:
I have a toast Object and for every key press event detected I inflate a view ,set the view elements within, set it to the toast and then show the toast.
Any idea what is going wrong ? code...

I should post this as a follow-up to my previous thread.
But I think this problem (may be) somewhat big so I create a new thread:
1. If a user install an alternative to 'Home'. (I'll call it 2nd Home)
2. He set this 2nd Home to launch by default for 'Home' action.
3. Whenever this 2nd Home crashes, their only choice is to reboot the system... ?
Because, after setting 2nd Home as default, the 'chooser' will not come out any more even if you press the 'Home' button.
In some case if this 2nd Home crashes in its initialization state, user can go no where, can't even go to Settings -> Manage App -> Clear Defaults
Am I missing something?

Is there any way to catch crashes in my own android app? Something like a global uncaught exception handler? Just wondering if I could install something like that, then if an uncaught exception is thrown, I could pop up a dialog for the user and ask if they want to mail a dump of the exception to me.
