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?

One of my friends with an iPhone showed me how a battery level meter is next to the bluetooth symbol when his headset is connected(new feature in iOS5 from what I found online). He was also using a cheap Motorola headset too. Is there an app or widget that does the same thing on Android?

Is there any way to show my smartphone battery level on my computer? Synced via internet.
It will be sweet to have those two bars (notebook and smartphone battery level) next to each other on the taskbar (win 8). I tried to google it, but unsuccessfully.

I'm having a small issue with my current phone and headphones. The problem is that headphones and phone have no problem with higher output volume. Temporary solution - speaker boost, trouble is: it causes any equalizer to FC.
How can I increase the volume at kernel level? If that's not possible then rom level would be enough. No apps, just pure source changes.

First problem is , Video recording has much noise , I think its due to high microphone sensivity. Is there any way to calibrate o change its level?
Second problem is , Speker volume in Jelly bean is too low and it causes some problem for ringign and allarm. is there any way to change its level?
I read in some threads that there are some CSV files located at /system/etc that we can change microhpone and speaker level. but I cant find in JB.and another configuration file named asound.conf that we can specify sound level in dB , but i'm afraid that it cause high voltage , and high current subsequently and cause speaker be corrupted..

Is it possible to create a lockscreen replacement at the application level that replaces the device's security lock, whether it be PIN, passphrase, pattern or face unlock, or potentially a new method? I know it's possible in the framework level, and have done it before, but I'm just wondering if it's possible to do it at the application level.
So far the few lockscreen replacements that I've tried only implement a slide gesture unlock lockscreen UI, and falls back to the device's security lock after that.

Ever since Google started allowing offline maps (both in the old Google Maps incarnation, and in the current one), I have found that when I download a map section for offline viewing, often there are many details missing (small street names, for example).
Any way to make Google maps download map tiles to their maximum level of detail (the level you could get if you zoomed in all the way), including all street names? You'd think this would be a given, but it seems not to be.
Searching around for discussions of this, most articles and forum threads are just about tile caching in general, not level of detailed cached.

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?

It may be a low to mid level phone, but can anyone explain how that makes a difference on whether someone should buy the phone or not. Is there really anything that intensive that people would be running on their Android phone (except 3D games)?
What problems do you expect people to be having with the Aria because of this outdated processor and low resolution?

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?

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?

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...

Android Version: 2.2 (but also happened on 2.1). My phone's battery level will suddenly drop to 89% even though it is still on charge. It's annoying because sometimes you'll start the day with only 89% charge instead of 100%. My friend also has a Desire but is not experiencing this problem - the only difference between them is the version of kernel. I read somewhere that is was the kernel that was the problem and somebody found a fix - xda developers - View Single Post - [DEV] Desire GSM/CDMA kernel 2.6.32 Google / 2.6.34/35 Cyanogen Mod.

Hello, I would like to ask what settings are necessary for my application to be available on all screen sizes: Is it enough to compile it using SDK 1.6 (but target is set to 1.5 and API level to 3) or maybe I have to set target to 1.6 and API level to 4?

How to decode a base64 encoded string to byte array on Android API level 7?
Can it be done using any standard packages of Java?
Should i copy the source code from google search results?
Should i re-implement encoder and decoder according to RFC?
API level 8 has util package android.util.Base64 that does this, but i have to do development based on API level 7.
