General :: API Level Differences - App Works In Level 10 But Not In Level 7?

Jul 2, 2012

I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

09-04 04:24:21.485: E/AndroidRuntime(6834): Uncaught handler: thread main exiting due to uncaught exception
09-04 04:24:21.510: E/AndroidRuntime(6834): java.lang.VerifyError: [code]....

There seems to be a problem with an uncaught exception and reflection, although....why does it work on API level 10?

Android :: Way To Write Droid Broadcast Receiver Detects When Phone Wakes Up?

Apr 5, 2010

I want to figure out how to detect when the phone wakes up from being in the black screen mode and write a handler for that event. Is that possible? It seems like this would be something a Broadcast Receiver should handle? Or is there a better or more proper way?

HTC Incredible :: Car Stereo No Longer Detects SD Card After Upgrade

Aug 31, 2010

I've been really happy with my Incredible since it came out.I even got a new stereo for my car, an Alpine CDE-102, because I was able to plug my phone into it and it would start playing my music off the SD card.
Today I updated, and now my stereo does not detect the files on the SD card.I think it is only looking at the phone storage.Was the phone storage given some kind of higher priority in the update? Is there any way to keep my phone storage from being mounted?

Android :: Noise During Video Playback

Aug 19, 2010

I have noticed that during playback of video I take with my Motorola droid, I hear a sort of a pop every now and then. The first time I heard it, I thought it was something going on around me when taking the video, but it's not, it appears that the sound is coming from the droid, though I do not hear the pop when recording. There is no rhyme or reason to it. Sometimes you don't hear it at all, sometimes it's every 30 seconds, and a lot of times, I hear the pop right at the end of the video, but sometimes it happens right in the middle.

Android :: Filtering Sensors Noise?

May 21, 2010

I'm programming an Augmented Reality application. It's development it's in an advanced state but I can't place the icons on the screen so still as anothers programs does (Layar, in example). This is because of the continuous variations of the sensors. I've tried the three modes of the sensors (FAST, GAME, and NORMAL) but I only get them to move more or less fast. The shivering is the same at different speed.

Finally I thougth I could reach my goal with a digital filter, averaging historical values. But again the icons continues moving, specially the most far placed ones (in the z axis). Please, could some one help me with some clue?

Android :: Filtering Accelerometer Data Noise

Oct 28, 2009

How do I filter noise of the accelerometer data in Android? I would like to create a high-pass filter for my sample data so that I could eliminate low frequency components and focus on the high frequency components. I have read that Kalman filter might be the best candidate for this, but how do I integrate or use this method in my application which will mostly written in Android Java? or can it be done in the first place? or through Android NDK? Is there by any chance that this can be done in real-time?

Android :: Can I Programmatically Detect White Noise

Oct 7, 2010

The Dell Streak has been discovered to have an FM radio which has very crude controls. 'Scanning' is unavailable by default, so my question is does anyone know how, using Java on Android, one might 'listen' to the FM radio as we iterate up through the frequency range detecting white noise (or a good signal) so as to act much like a normal radio's seek function?

Android : Phone Making Loud Shrill Noise / Way To Fix

Jun 13, 2010

When I make a call everyone is telling me that they are hearing a loud shrill sound but I hear nothing so I went to Verizon to get an exchange since I have the insurance. They checked my phone out and said it should be exchanged but when they tried to exchange it they said there was none in the store and none even at their warehouse and they had no idea when they would get more. I'm wondering if that is because of the new Android phones coming out.

So if I have to get another phone I want to be prepared to make a decision. Any thoughts on another Android phone? I absolutely love my Droid and hope they will be able to get more in so I can exchange mine. But if I can't I would want one just like the Droid as far as a physical keyboard and also I like the amount of memory. And I want the freedom I have with the Droid to install anything I want. It's the first phone Verizon hasn't locked down.

Anyway hopefully I can keep my Droid but as I said I just want some ideas in case they don't get any more Droids in stock. Oh one last question, I was talking to an ex Verizon employee who insisted that the Droid won't accept a 32GB card. Is this correct?

Android :: Is API Level 6 Gone?

Sep 21, 2010

I have updated my tools to revision 7 and now I can't do a build as it says the API level is obsolete. I can understand warning but it won't build at all. I am using android.bat to generate a build.xml for release versions. So the build.xml gets made from scratch each time. If I switch to --target 8 it builds but I have already released it on the Android Market with 6. Won't this mean that some people that have Android 2.0.1 won't be able to run it?

Android :: Silent Profile Active - Text / Emails Still Make Noise

Aug 6, 2010

So I downloaded Tasker and created a profile that's supposed to silence my phone when it's plugged in at night, and it almost works. Tasker says the profile is active and I can see the "silent" icon in the notification bar, but texts and emails still make noise. As far as I can tell, Silent Mode is also supposed to silence notifications, but it's not working for me. I'm using Handcent SMS and Gmail.

Android :: Low Level Audio API

Aug 9, 2010

I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.

As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?

Android :: Low Level Debugging ?

May 15, 2010

Is there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower? For example show what functions are being called from the libcore folder. I am also interested to find how it communicates with the linux kernel at the bottom of the layers. Is there a way to do this?

Android :: Getting Values From XML - API Level 3

Jun 24, 2010

I have a string that contains a xml structure and there are two pieces of data in separate tags that I am after.

xpath has been added since API level 8, and with me being stuck with API level 3 (old phone for you ;-)) I need a way to get the data.

Would using a regular expression commit a huge sin? ;-) The xml isn't that big...

HTC EVO 4G :: HTC EVO Wall Charger Noise

Jun 22, 2010

I have noticed that while charging my EVO using the stock wall charger and any micro usb cable that there is a loud whining noise. It is pretty loud and can even hear it while watching TV. I have read that the Droid Incredible charger has the same issue as well and have tried to switch the prong orientatoin and still no luck. I have used my other HTC charger that I have from my old Touch Diamond and don't hear any type of noise. I have read that it is the capacitors in the charger making the noise. I have tested and the charger still makes the noise after the green LED light has come on.
