I am trying to create a very simple help page in my app. The layout xml for the page contains only a textview that displays the help info. In the Eclipse layout view, the layout looks perfect... however, when i try to load it in the emulator (via an OptionsMenu) it comes up as a blank black screen.
Here is the Code:

Trying to create a WebView but it only shows a blank/white page. I have followed several examples and they all say that work with this code...
Here is my code:

I used webview to visit https link. the page always show blank. i found the way to dill with it

That's work fine.
But i used API Android 2.1, the above method is belongs to Android 2.2.
I have an android application that loads web pages in an activity with a WebView. I am using the retrieving the page manually and using WebView's loadDataWithBaseURL to display it on screen. Everything there is fine.
Now, i am trying to override the Back button press to simulate going back in the WebView history stack. I am able to override the Back button press, i can see that there is a history stack in the WebView, i can see that the history url is correct, but when i call WebView's goBack() method, it displays a blank page.
If i use WebView's loadUrl method, the Back button with an override works as intended. But why.... If i need to handle this manually, how do i start messing with history pages?
Noticing that since the latest Chrome updates you open a web page and all you get is a blank page? I have been having this happen a lot lately since the last update(s) Also it doesn't seem to matter which brand phone, it's happening on HTC One, LG Optimus GPro, and Sony Xperia Z1.

View 3 Replies View RelatedI have the tronsmart CX-919 mini pc running 4.2 and there is an issue with the browser reverting back to the home page or the previous page. When I try to display a webpage on our intranet it reverts back to the homepage or previous page after about 3 hours. I need it to display constantly. I read somewhere that it was a Download Manager issue and disabling it would work but I can't find where to disable it. Also it was stated that Flash was an issue but i tried uninstalling it and it just reinstalled itself and the problem kept occurring. I just want to display a page in a browser and for it to stay on the screen (full screen) until I manually navigate away from it. I plan to leave it on for weeks at a time.

Also, it seems to save the history, even after I delete history, cookies, caches. Why? I was told to try and keep this, as well as deleted email, empty or the phone may become slow.

View 1 Replies View RelatedI'm trying to connect to connect to my T-Mobile G1 to test a simple android app I an creating. I cannot get it to show up in the list of connected android devices. Here are the details: 32-bit Windows XP I have enabled USB Debugging on my device I am not prompted with the New Hardware Wizard when I plug my device in, it is merely seen as a new removable drive. It does not appear under any other categories in Device Manager, nor is there a new "Unknown Device" entry anywhere to be found I have tried "Update Driver" and select the driver that Google provides for their official developer devices, but it says "this driver does not match your device" or something to that effect. Probably because it is expected a device type other than "Disk Drive"I have tried uninstalling the device under "Disk Drives" and plugging it in again but it always gets reinstalled automatically as a "Disk Drive" have tried uninstalling the device, manually installing the Google driver from the INF file and plugging in the device and it is still only recognized as a "Disk Drive" Most importantly, I get a blank device list when I run "adb devices" from the Android SDK tools directory before and after each step I tried After hours of scouring the web I get the distinct impression that a new device category should be popping up in Device Manager if the driver is installed correctly, but I have not been able to get the device to come up as anything other than a new "Disk Drive"
View 2 Replies View RelatedMy app has one activity and one ContentProvider, the activity is simple in that it's just a splash screen at the moment with no other logic in it (I do intend to have more activities in the app). The ContentProvider uses SQLite as a back end and loads some static data from files on first install, a slow process due to file sizes and database initialization. My problem is that I want the activity to show up as soon as the install starts and maybe display a progress bar or dialog to show the user progress about the install. At the moment I get a blank (white) screen while the ContentProvider is initialising the data which takes quite a long time and I get "Activity idle timeout for history record" warning in LogCat. My splash screen only shows when the Content Provider is done, from the app standpoint this is undesirable behaviour. One potential solutions would be to manually start the provider via an AsyncTask but I have a feeling that this is a bad approach due to the fact that if the activity is interupted and restarted while the install is underway and a new AsyncTast is created through the activity's onCreate() then I'll have worst problems on my hands. Is there a way to start the content provider in the background and display my splash screen activity straight after the app is started? Note that this problem is only an issue on first install.

After this I am getting activity launch timeout and Idle timeout. Is there any design issue with my activity or problem with android environment.
If I want to enforce a maximum length of input in an EditText field, I can use the maxLength attribute. But if I want to enforce a minimum length (in my case, simply non-blank), I find no corresponding minLength attribute. I've also looked at the various 'inputType' attributes (phone, password, etc) but I don't see anything like 'required' or 'non-blank'. I can't believe this would require a custom input filter; it's more likely the answer is so obvious it just doesn't get written down in the form I'm asking the question.

I have a simple app that I am building to get the hang of android's development environment - and things like click events, etc..
The app loads, and I am able to change the text in a textfield using a button handler. However, when I import the location class, and try to do a simple GPS call, the application crashes.
The problem is, everything looks good in Eclipse (error console) - and I'm not seeing any exceptions in the android emulator (DevTools). I have the logcat window open, but I haven't done anything in eclipse/code to send logcat anything (do I need to?)
Is there a better way to troubleshoot?

I ran into a rather strange problem with my OpenGL game. While most textures look good, five or six are not drawn on Droid, and I don't see anything special about these images/models. For example, my HUD is made of 4 elements. The upper part is drawn correctly, while the lower part appears as white rectangles. The code used for loading and drawing these models and textures is exactly the same. Textures are 32-bit TGAs in both cases, POT dimensions, in - nodpi, inScaled==false, using GLSurfaceView to rule out configuration issues. No problems on G1 and Hero (and of course on emulator). And I don't have the Droid, so I can't just try whatever comes to my mind. Asked users to send me logs - no errors, all models and images appear to load normally.
View 2 Replies View RelatedI've got a basic list activity with a few images that when you select one starts a new activity with a SurfaceView (based on the Lunar Lander sample). Some times the screen is just blank, from some debugging I can see that the background .png is being loaded and doDraw() is being called by the activity doesn't display anything for anything from 4 to 20 seconds. Other times the game activity is loaded just fine. I assumed it was some kind of garbage collection problem but I can't see anything in LogCat and the second activity is actually loaded, just not displayed for some reason.

View 4 Replies View RelatedI'm creating a basic Mapview application which will display my current location on the google map. Initially i had many doubts while creating the application, but thanks to android developers archives that helped me to reach this point. I have followed almost all the threads on the android developers site but still unable to see my location on the google maps. It always shows a white screen on the emulator with google image at the bottom. Please help to make it work. From most of the threads I learn that we need to sign our application with the correct fingerprint. I did so but unsuccessful.
The following will explain the steps:
1. Using sdk version android-sdk-windows-1.0_r1
2. Created a new android application.
3. Signing the application:
a. C:Program FilesJavajdk1.6.0_13in>keytool.exe -list -alias androiddebugkey -keystore "D:Profilesfknq86Local SettingsApplication Data Androiddebug.keyst ore" -storepass android -keypass android
b. Certificate fingerprint (MD5): 75:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:33 where XX=some alpha numeric data
c. signing up for an Android Maps API key!
Using link http://code.google.com/android/maps-api-signup.html 4.
Code below: There are 2 applications
1. Find Me
2. ShowMyLoc.
FindMe has a button which directs it to ShowMyLoc (using Intent) to show the location on the google maps. For simplicity sake i'm pasting the code only for ShowMyLoc app.
