My PreferenceActivity contains a nested PreferenceScreen in another PreferenceScreen and I'm applying a theme to my PrefenceActivity that changes the background color. However when I open the nested PreferenceScreen I get a black background and I cannot see the options.This happens with android 2.1 , but it does not happen with android 1.6.Any ideas on how this can be corrected?

When i fire up my youtube app, i get a quick black screen flash and it goes back to home screen. The app doesnt launch at all. It was working just fine for several months, all of a sudden it started doing this.
View 8 Replies View RelatedThis was reported in the other thread about X8 Issues, but thought to start a new one to gather feedback from users. It's about the ''black screen'' freezing issue encountered by some users. I have had this several times since owning the phone for a few weeks, so it is a recurring issue. Problem: The phone hangs or appears to be shut down or become unresponsive suddenly. Pressing the hardware buttons doesn't help as the phone doesn't react at all. Solution: Take out cover and battery and restart.Observations: From my own observations, it's not actually a shutdown but a major freezing/hanging. Sometimes when it happens, I can still see vague shades of the display at an angle. After leaving the phone for a while in the pocket, the phone comes back to normal again. Not sure if this is true for all users with this problem. Anyway, gathering more feedback to see how prevalent the problem is, to evaluate whether I should take it to the SE service centre, or whether doing so will help at all.

To end the call (or enter numbers in a call menu) I need to press the sleep button to get the screen to light up again. This is a pain in the a$$.I have the screen timeout set for 2 mins.
2) About once or twice a day the home screen will lock where I can't press anything. I need to reboot to fix.
Sometimes when I hit the screen/power button the screen will stay black and i can see the menu bar up top fine but all else is black. If I hit the home key then all lights up fine. Then sometimes Ill hit the button and it works fine.

View 8 Replies View RelatedThere is an activity which fetches xml data from the network, parses it and displays it in the UI. When the user clicks on any of the link or button on the screen I call startActivity with new Intent object of the same activity. I do this to have the activity on the history stack. Previously I just called setContentView of the activity without starting the activity again, but with this I cannot have the previous page in the history stack.Now the problem is - each screen normally takes up to 20 seconds to fetch content, parse and display. when the startActivity is called the screen becomes black until the next UI is rendered. I wanted to keep the previous screen showing until the next page loads.Please tell me 1. Is there a way to do this? 2. Is it good to start the activity again for each page. If not how to have the previous page in the history stack so that I can use the Android's back button.

I have a listview that when you click on an item it will take you to a WebView that displays some static formatted text associated with that list entry.
I had it all working with a TextView but I wanted to be able to use HTML formatting for the text and figured the WebView was the way to go. Right now it is just supposed to display a generic link for testing purposes but when the viewContent intent starts it just goes to a black screen. I can go back and pick another entry and it also just shows the black screen.
I'm not sure what code you are going to want to see so here's the viewSection class file and the viewsection.xml layout.

My Tablet shows black screen after a while animation android logo and no more work. So I tried factory reset. But factory reset doesn't proceed to recover menu. It shows only factory reset logo (Android logo with red triangle) like screenshot.
My tab has only 3 button (power, Volume up and down). I tried both of them. But the logo doesn't move. How to factory reset?
My tab Configuration:

View 1 Replies View RelatedI've a lot of initialization code in my main activity's onCreate(). When I launch my game, the screen goes black for a long time, then my game appears. I did logged some message at the start and end of onCreate() and found that onCreate() is executing its code while the screen is black. Sometimes the screen goes black for too long and phone shows a popup dialog prompting me to choose between Force close/Wait. Then when onCreate() is completed, my game appears. Choosing 'Wait' then dismiss the dialog.
I tried using progress dialog described in this article:
http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog
But it doesn't work. The screen goes black for the same amount of time even after I use the progress dialog.

View 2 Replies View RelatedI wrote a service and I registered BroadcastReceiver in it. In the onReceive () method of BroadcastReceiver catagory,I just wrote Intent.ACTION_TIME_TICK.equals(intent.getAction()) to receive the systenm time every minute and deal with everything that I should do in it every minute.But i found a problem that when the mobile phone screen was locked and was completely black,my service seems to be sleep and does not work,and when I light up the screen(it is still in locked condition),the system will automatically run my service.I do not know the reason,I guess if it is because my service is not the system-level service? When the mobile screen is black,Andraid system will hibernate the sevice which is not the system-level service,so if this,I should add my service to system service,but I know how to use android.permission.ADD_SYSTEM_SERVICE? If you can,please send me a example about how to add own service to system-level service.This problem has been troubled me for two weeks.
View 2 Replies View RelatedHas anyone seen their MapView which was working in 1.1 displaying a plain black screen (no errors) after compling with the 1.5 SDK? I made sure to copy the debug.keystore from the 1.1 location to the new 1.5 location so its compiling and loading on the phone correctly (I did a reinstall not uninstall/install) and shouldn't need a new mapsAPI key.
No errors are showing up in DDMS other than: Failed to find provider info for com.google.settings
I am trying to get a slide down animation to work, and it seems to work except that it starts with a big black screen instead of the screen that was there. So I have layout1 and layout2. When I start the animation using ViewFlipper.showNext it puts a big black background over layout1 and then slides in layout2. If I use ViewFlipper.startFlipping() it slides in layout2 out as it is sliding in layout1 -- which is what I would expect.
My slide_down.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="0" android:toYDelta="100%"
android:duration="4000" android:detachWallpaper="true"/> </set>
My java code looks like this:
ViewFlipper vf = (ViewFlipper) findViewById(R.id.DropDownList);
vf.setAnimation(AnimationUtils.loadAnimation(this, R.anim.slide_down));
vf.showNext(); or vf.startFlipping();
Whenever I start any Android Application, initially a black screen comes to the foreground for a split of a second and then the splash screen comes up of the Application. Can anyone let me know the way of avoiding it?

I've been banging my head against a wall this afternoon trying to get a WebView to work. Below is the code in the main class:
public class fkyougoogle extends Activity {
/** Called when the activity is first created. */
WebView webview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
// WORKS
//webview.loadUrl("http://www.google.com");
// DOESN'T WORK
//webview.loadUrl("http://www.theregister.co.uk");
//webview.loadData("<html><body>hello</body></html>", "text/html", "utf-8");
//webview.loadDataWithBaseURL("fake://", "<html><body>hello</body></html>", "text/html", "utf-8", "http://www.theregister.co.uk/");}}
This is Google's "Hello, Webview" example. If I use a WebView and try to access www.google.com then it works fine. If I try to access any other site then it fails including loadData and it just displays a black screen in the emulator. In the end I would like to read from a local file.
is included under the manifest tag and the XML schema is the same as the Hello Webview example.
Am I missing something obvious here?

I've been block by this question for about a week. I tried to implement a simple application: show a image, when user touch on screen, I want to create a GLSurfaceView to cover the previous image. Then show some 3D effects on this GLSurfaceView.
The logic is quite simple. But I have a serious problem. When GLSurfaceView comes out, the whole screen become black, after 1-2 seconds, the GLSurfaceView with texture shows up. Is there any way to make this smoothly? The 1-2 second black screen is really a bad user experience.
Recently my phone feel so slugish and the mp3's are not playing on any music app. Ive searched through the internet that if i do a hard reset and clean dalvik cache that should fix it. But when i done that something went wrong with my android phone. It boots with no problem but when the boot finishes the screen just go black. I know it is booted cause it vibrates when i press the buttons(haptic feedback) but its just black screen. Im using mt6516 android platform phone. Cherry Mobile Candy to be exact.
