Android :: Unused Java Hardware Acceleration On G1
Mar 31, 2009
Can you confirm that the G1's Qualcomm MSM7201 CPU does not support java hardware acceleration? (Re: Android game developers desperately need optimised game engine example code). I'm reading here[1]:
"528 MHz ARM11 Jazelleâ„¢[2] Java® hardware acceleration"
And from what I've read on the net, MSM7201A-a is the dual-core CPU powering the G1. So, can you confirm that Android could be faster, if Android could use the Java, instead of the Dalvik VM, and that this didn't happen because of Sun?

I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well.

Has discovered a way to rid of mouse acceleration in android?
Here is a good explanation of what mouse acceleration is:
Without mouse acceleration, the movement of the mouse and the movement of the crosshair will be 1 : 1.
With mouse acceleration, the movement is based on speed. Meaning, if you move the mouse 1 inch, slowly, it'll move one distance. If you move it still 1 inch, but fast, it'll move a lot farther.

I'm just wondering...on Android Web, I could find two completely opposite ways of defining which direction the positive X acceleration is. http://developer.android.com/reference/android/hardware/SensorEvent.html At the bottom, it says "When the device lies flat on a table and is pushed on its left side toward the right, the x acceleration value is positive. " However, http://developer.android.com/reference/android/hardware/SensorListene..., it says "When the device is pushed on its left side toward the right, the x acceleration value is negative (the device applies a reaction force to the push toward the left) "

I have some resources in my app that are going to be loaded optionally for different brands. I don't want to set up entirely different projects each time we re-brand the app so I want to know if the resources that are not used will be always packaged in and if there is a way to avoid this.

Maybe I am misunderstanding something but I believe Android is supposed to automatically kill "unused" tasks after a while. Is that correct? I own a Galaxy S and I see that I still have in the running tasks list some apps that I haven't used for more than 18 hours. And these taks do not make any kind of auto sync, they communicate with the network only when used actively. Am I misunderstanding something?

I'm looking to increase the speed/acceleration of a bluetooth/usb mouse on my android tablet/phone/any other android device. I've noticed there are no such features/options when pairing the device in honeycomb/ICS (via settings). My device/s are rooted.

I have a ton of folders on SD card and some places on my phone's internal storage that I want to know how to delete, bottom line is some of them are important folders that may be required by the system - some contain downloaded data from games and what not - such as The Sims Freeplay - that range in sizes from 400MB to 900MB.
I'm running on a stock phone, HAS NEVER BEEN ROOTED,

I did was use the search function and after 10 pages I could not see what I was looking for. In java, we use method parameters for a number of reasons but I've never used parameters in my methods unless I needed them..When defining a method in android for a button that I want to click, I had my method defined in XML under the Button element
[HIGH]androidnClick="showText"[/HIGH]
then, in my ProjectName.java file I defined the method
[HIGH]public void showText(View view){
}[/HIGH]
I was told that the View in the parameter is the view that was clicked.Button is a subclass of View as is TextView and since that is the case,is this the rule for just the onClick method? Also, why can I not pass the Button as a parameter? Button is the actual "View" being clicked, so why not Button?
Furthermore, are there other methods similar to this and if so, do they all follow the rule just like the View parameter, where let's say if I had a class called "A" and it had a subclass "B" and that class had a subclass "C", and if I wanted to use the onClick method, I can only pass the Highest Class as the parameter?
To simplify that, are there ever cases where I would pass anything else OTHER THAN "View" as the parameter to these methods?

I have been having problems trying to keep the wi-fi ON for a continuous period of time. Every time i turn on the wifi, and leave the phone idle after using an app, the connection is automatically disconnected. I did change the advanced wifi settings sleep policy to Never, but still shows disconnected. I am sure that i am well in the range of my wireless router and that it is switched on at all times. This is very annoying cause i have to turn ON and OFF the wireless adapter on my phone to regain connection to use other apps.

I want to create a light rom for my RK2818 tablet. I removed lots of apk's, and it works fine. Now, I want to delete the unnecessary languages and dictionaries from the keyboard (LatinIME.apk).
How can I do it? Can I simply remove the folders like resaw-da with Total Commander (compression set to 0)? I want to keep English and Hungarian languages only.
I'm also interested in more tips to speed up this unofficial cyanogenmod 2.3.7 rom, because this old chinese tablet with 256mb ram is only used to watch movies and browse the internet. I've already updated the hosts file with the adfree version, and removed the following apk's:
ADWLauncher.apk (replaced with LauncherPro)
Bluetooth.apk (no BT in this device)
Calendar.apk
CalendarProvider.apk
Camera.apk (no cam...)
CMStats.apk
CMUpdateNotify.apk
[code]....
Can I remove any of these? I want to remove everything wich is not important.

I need to download a root in order to Delete programs I don't use? (such as "City ID" and "Skype" and all the others on my Apps panel I don't use, ever.) Am I correct? Also read on the "Sticky" that task killers actually slow my phone down? I use advanced task killer free and it makes my battery life way longer and gives me the ability to kill stuff I ain't using.
I really like the phone a lot! I use the barcode scanner and the google goggles (which I think needs some more work IMO) and constantly google stupid stuff at work that me and the guys come up with. I really like the phone, but wouldn't mind getting rid of some useless programs I have. (Like on my home PC). Not to forget the Full version of Angry Birds. I'm addicted to that game! Its awesome! (reminds me of the game "Gorilla" that windows NT used to have).

I'm about to retire my trusty old Epic 4G and whats the best way to store my battery on it. I will be removing it but I'm not sure whether I should store it fully charged or half way charged. If I remember correctly, I read somewhere that you should store your battery with 50% charge for it to have some life if you ever need to use the phone months or a few years time. Storing it fully charged can pose a threat due to the battery blowing up?!?! Not sure if this is correct or not. What to do to preserve your unused batteries in your old phones?

I just rooted my stock 2.1 Droid and am playing with all things I now have access to. I realize I can now delete just about anything in the /system folder. I have already removed a few stock apps (like the Visual Voicemail). I suppose I could also remove unused wallpapers, sounds, etc., but would freeing up this space offer any benefit?

I synced up with my computer after uninstalling unused apps and clearing the browser cache and a few others, just general clean up to keep the phone running smooth. After roaming around my sd card, I came across this. A total of 84 cache files totaling 3.24mb. What is this from and is it ok to delete them? I'm assuming it is since it is just cache, which you can delete any of theme xcept for google nav (force close issues).

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
