I am trying to create an app that gets the location and telephone number of the phone. This is the Code I am using to get the telephone number (I am focusing on sdk 1.5) and in the emulator this works.

The application My App (process com.mycompany.android) has
stopped unexpectadly. Please try again.
So, I think I need to code for this issue. In order words, when rotate the device from landscape to portable or from portable to landscape, application needs to catch this event.
Is it right ?
How to make it ? What is wrong here ?
Is it possible to test on the emulator ?
I just bought the Nexus One unlocked for AT&T and really like it. 1 wierd thing is that when I rotate the phone counter clockwise, the screen goes to landscape just fine; but when I rotate it clockwise it does not go to landscape "the other way". And, if I'm holding the phone 'normally' and rotate it 180 degrees ('upside down') it doesn't follow.My youngest daughter delights in telling me that her iPhone does this with no problem. What's up with that?

I have a series of OpenGL-ES calls that properly render a triangle and texture it with alpha blending on the emulator (2.0.1). When I fire up the same code on an actual device (Droid 2.0.1), all I get are white squares. This suggests to me that the textures aren't loading, but I can't figure out why they aren't loading. All of my textures are 32-bit PNGs with alpha channels, under res/raw so they aren't optimized per the sdk docs. Here's how I am loading my textures:......................
View 4 Replies View RelatedI'm developing an App that sends keep-alive packets to its server to ensure the connection is still alive.
The server is java based and thus easily to run. I run the server on a virtual machine (Windows 7). After my App is connected and the first keep-alive packet is received (it displays a message in its console output) I disable the network interface in Windows. This step is very important because by disabling it, there is no way to send any packet back to the client informing it about network changes.
The clients are configured to send every 25 seconds a keep-alive packet, so you don't need to wait long.
When you use the sample JavaClient on Windows 7 it takes less than a minute after the keep-Alive packet and an exception is thrown which triggers reconnection (which currently can't occur). This is the expected behaviour.
When you use the sample Android App on an emulator (tested Android version 2 and 4) it is the same behaviour. So in less than a minute after the keep-alive packet it recognises that the connection is dead, throws an exception, this triggers reconnection.
Problem is now when this App runs on a real device (tested several, Xpearia Arc S, one Cyanogen Mod 4 on Galaxy S3 and my Galaxy S3). I've waited 5 minutes, but there was no exception. This behaviour is reproducable.
Since this is a sample App, it uses no wakelock or service, so to test it is important to have it in foreground all the time (don't switch to other Apps or homescreen) and increase your display timeout to a few minutes to ensure that it doesn't go off. Use Logcat-Output to get informed whats happening, because there is no output in the App itself.
Now Sample-Code is in the attachement. Something had gone wrong. The Code consists of 3 Eclipse projects which you can easily import.
Is there a way to check if our code is running in the emulator vs a real device? I'm using a Map View which requires a signing key. I'm using the signature of the eclipse debug key when running on the emulator, but this won't work when I build a release version. I think I need to have a check to see if I'm running on a real device, and set it to the real release key at that time.

I've created a layout with an image view and a web view. The web view is set to have a default visibility of gone. When the activity fires up it displays the image view first and when the web view has finished loading its url, it marks itself as visible and the imageview is marked as hidden.
When the imageview is shown, I would like it to rotate repeatedly just for a little added pizazz.
I have never done animations before in Android and all the posts I found when I asked the internet were not helpful; thus, I have returned to SO for help.
So if I start with this...final ImageView splash = (ImageView)findViewById(R.id.splash);
How do I create a repeated rotate animation and apply it to the ImageView?
I have a question: Is there any way to have such a thing: [URL] ..... in Xperia Play 2.3.4 gingerbread?
I do not want custom room... I would prefer apk or package for flashing .
Does anyone know of an animation/method that can rotate an image around smoothly to face a point, such as where the user is touching?

I have developed and tested my app on the emulator, and now want to install it on my HTC device. the apk installs successfully, however my database is not going with it. I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem

View 3 Replies View RelatedI'm currently hosting an app on my own server so my beta testers can test it. I've set up the apk MIME type to be application/ vnd.android.package-archive, and when I try to download the app from the emulator, it downloads the 53KB apk file and installs it. When I try to do the same thing from a real ADP1 device, it only loads 43KB. When I try to install it, the system says that I'm trying to install an app that already exists (called "Android System") and that doesn't require any permissions, but nothing happens when I proceed. logcat tells me
"D/asset (16379): failed to open Zip archive '/ sdcard/download/[name of the app].apk'
Bonus points! When I try to download the app from the emulator, I can see that in the accesslog of my server. Not so when I download it from the device, even after deleting /sdcard/download/* and clearing the cache through the settings. Almost as if the device was loading an old copy from a proxy server. I'm not sure which APN I'm using, but none of the T-Mobile APNs have a proxy AFAICS. Is there a way to circumvent the proxy, assuming that this is the case? And/or tell the proxy not to cache this apk file?
Running into REALLY interesting problems with OpenGL ES. Basically when I start my program in 1.5 or 1.6 emulator, it works just fine but on HTC Hero 1.5 it does not. The problem is that the vertices are not being rendered but the gl.glClear() command is working just fine. I followed in with the debugger and it does go into the rendering function and such but still not rendering the vertices...

Why is the actual phone not rendering the vertices like the emulator is?
I have an android application that parses some HTML, downloads an image, and displays it. I'm using an AsyncTask to do the HTML parsing and image downloading, but that shouldn't be relevant. I never have a problem when I'm on WiFi on my phone, when I'm using the Eclipse debugger on my phone, or when I'm using the emulator. When I have my phone on the cell network (even with pretty good reception), the image sometimes fails to display. I'm having a hard time figuring out what is wrong, since the problem cannot be reproduced in the debugger. Does anyone have any idea what could be wrong?
Update: I have narrowed it down to the image downloading function. This way my original code:.......................
As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!
