Android :: Android Launch Modes
Apr 13, 2010I am finding it hard to understand the exact circumstances in which each the various launch modes would be used in Android.

I am finding it hard to understand the exact circumstances in which each the various launch modes would be used in Android.
I am looking for a way to add more advanced blend modes to my program (ones that I could define myself). How would you suggest going about this with Android?
Setting pixels individually is too slow to be a viable solution.
Android boot modes.I have searched but couldn't get concrete reference.
1) What are the different boot modes of Android?
a) Normal Power up.
b) Recovery Mode
c) Download Mode
i) Fastboot
ii) AP Fastboot
iii) BP SBF Flash
iv) BP Only
v) BP HW Diag & Boot AP
vi) BP Tools
2) What is the difference between these modes?
I think "recovery mode" clears cache, takes "update" from sdcard.But in "Download mode", we can use fastboot protocol to "Flash" the device.
I know several of you wrote your apps and games before 1.6 was out or before you had a trusty N1 or Droid to test on. This led to many apps that rely on compatibility mode, that is, a width (when portrait) that is always 320 to make things work out. For 3D games, this made our games continue to work because when the games are run full resolution, our 1.5-compliant textures get scaled up automatically and become non power-of-two, causing white or black wherever a texture should be drawn (and then users complain that our games are nothing but white!)Well I wasn't very worried about it and I still have a few games in compatibility mode but recently a user contacted me, telling me that one of my games (Light Racer 3D) and a few other 3D games were all white on his Droid. I asked him if he had ever run any kind of tweak utility and he said that when he first got his phone, he installed an app called "Spare Parts" and played with some settings on it. Apparently one of the settings disabled compatibility mode and runs everything full-res, breaking many of our apps and games. Of course users don't know that's what they are doing. They think they are somehow unlocking their phone's potential that their evil carriers didn't give them access to. If only they understood!First of all, if you're the author of "Spare Parts", that's a bad idea. Please don't give users that option. Nothing good can come of it.Second, since there will probably always be some kind of tweak app out there that allows for disabling compatibility mode, it's in your best interest as a developer to update your old apps and make them work at every resolution. Counting on compatibility mode in the long term is a bad idea I think.
View 4 Replies View RelatedHere are the settings I am trying out as my "Power Saver Mode" for my HTC Magic (Rogers). Not sure yet how much of a difference this whole set up will actually make, but I'll try to make it a scientific study. Please take a look, I am interested in comments on the setup in general, and on individual settings (ie. will a particular setting really make that much of a difference to the over-all power usage?).As of the moment I changed all these settings, my battery is at 97% (After I turned on my phone this morning, all these settings were previously opposite so i could get my email, etc).
1. Screen Brightness 15%
2. WiFi = OFF
3. GPS = OFF
4. Auto-sync = OFF
5. "Enable always on mobile" = OFF
6. Background Data Usage = OFF
7. Use only 2G Networks = YES
I am also using these apps:
"TasKiller" to kill BG apps
"Useful Switchers" to modify settings.
It would be nice if there were an app that could work like the power setup in the system tray of Windows where you can choose different power modes for your laptop. A simple app with a Power Saver Mode, Balanced Mode, and Power User Mode that could all be set by the user.It would be nice to be able to run the app, choose the "Power Saver" mode and have it automatically change all the settings as I've listed them above, and then be able to choose "Power User" to reverse them easily so I don't have to go through all the separate steps to do it myself.

View 2 Replies View RelatedI've had my brand new Droid Incredible for less than a day. It replaced a BlackBerry Curve that I had for several years and really liked. One nice feature the BB had was that it would shift from ringing mode to vibrate mode by simply slipping it into its case. Absolutely nothing had to be done to the device itself, other than configuring it to do this. Given that Android phones don't have this feature, what is the simplest and quickest way to move around among ring, vibrate, and silent modes of operation? Any way to do it with a single tap or two?

View 3 Replies View RelatedJust wondering if any of the ROMs re-added the old 2.1 feature where you could switch from Volume on, to Vibrate only, to Silent mode on the phone. Since 2.2 it's either Vibrate with sound or vibrate in silent, and you have to edit the settings menu itself to get "just" silent or "just vibrate. Do any ROMs add this functionality?

The phone has been reset via settings>privacy>factory data reset twice. And i still cant get the vibrate functions from haptatic keyboard or ringers to work. He needs the vibration stuff back for work. If i cant figure it out it will have to be returned as nonfunctioning so unless im totally missing something

Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

View 1 Replies View RelatedIs it in any way possible to launch an activity from the main function without having a UI? i.e. is there a way to create a sort of "wrapper" around another activity, i.e. by launching the main activity, it takes you to another activity automatically. If that is not possible, is there a way to remove the main activity from the stack so that clicking the back button does not take you to a blank UI?
Here's an example of what I'm trying to do:
public class WrapperActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:555-1212"));
startActivity(intent);
}

I am trying to create a widget that, when clicked on, launches the browser and goes to a particular URL. Unfortunately, I have had a lot of problems. I started with a (working) widget that, when clicked, opened the alarm clock. Then, using the code from another Groups post (http://groups.google.com/group/android-developers/msg/ 11e54b1df3a4d279), I tried to convert it to open the browser instead. Here is my (non-working) code...

The problem is the apps will launch twice or more when I apply the following steps: 1. launch the app A (1 time) 2. rotate the screen, (the app A will launch again, now the app A launch twice) 3. press return button (my expected result is that the app A will keep running, luckily, I can do that.) 4. launch the app A ( there will be one more app A running) So, in this case, there are 3 app A launching at the same time. But my expected result is just have one and only one app A launch.
