[android-developers] Re: Camera + GLSurfaceView frame rate
Thanks for your response. On the Nexus 4 when I query for frame rate ranges I get 30 as a max but trying to set the frame rate doesn't have any effect. I'm not doing any format conversion in my code for the video frames but maybe there's some way to specify a different format? I'd particularly like to know if anybody's gotten this all working at a high frame rate purely from Java or if it's necessary to dig into the NDK.

I think you might be able to adjust this between at least 2 values, 15fps maybe 30fps options. Are you converting YUV to JPG camera preview frames ? If yes you will need to try to make this conversion as efficient as possible for good fps.

[android-developers] Odd ICS only, ScrollView/ListView, landscape only shadow at top of View
I am seeing an odd dark shadow at the top of all ScrollView and ListViews in my application that I can't seem to get rid of. The odd part about it, it ONLY appears in landscape mode on the Galaxy Nexus or in the emulator. It doesn't appear on any emulators running 2.2 or 2.3.x, nor does it appear on my Captivate running 2.3.3. Also, it doesn't appear on my Asus Transformer Prime running 4.0.3 in landcape mode, so it seems like the issue is localized to the Galaxy Nexus and the Android emulator with a 4.0.x based AVD. I do not have anything within the app that would provide a different theme/layout/style for orientation, nor OS version. Can anyone provide me some guidance here? Here are two snippets of a screenshot, one in landscape, the other in portrait https://lh4.googleusercontent.com/-6_zGD6D58sg/T5rJQYsstLI/H60/unOKwwXjs4Q/s1600/anotated.pnghttps://lh5.googleusercontent.com/-EOunVBMNXz0/T5rJeDp6rfI/H7A/ujyLWFP7Ta0/s1600/missing.png https://lh4.googleusercontent.com/-6_zGD6D58sg/T5rJQYsstLI/H60/unOKwwXjs4Q/s1600/anotated.png -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] device testing on iOS app port
I've completed an iOS app for a client and they've asked me to do an Android port for them. I haven't written any real Android apps before but I've been hacking around on some of my own apps and studying the docs long enough to feel confident that I understand the APIs and conventions well enough to do the port. However, I'm a little concerned about testing. I don't currently own any Android devices at all. I'm willing to buy 2-3 devices for testing purposes but I don't have the budget to buy more than this or to subscribe to one of the online testing services. So before I commit to this project, I'd like to ask people with more experience this: are two or three different phones enough to test a relatively simple app before release or would I need more to represent the large number of different devices out there? -- miles -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Hook event listeners for activity/application lifecycle events
Hi, Is there any way to to listen for activity/application lifecycle events without having to extend the classes? Reason for this is we are providing a component that needs to detect when an activity/application is paused or resumed. And for convenience sake we don't want the client to have to notify the component every time activity lifecycle changes. If possible we just want the component to hook into the lifecycle events and be informed automatically by the android system. We could make the component extend Activity and let the client extend the component, but this would be more complicated for the client. We want to keep things simple for the client as possible even if it makes our component more complex. So is there a way to hook event listeners for lifecycle events? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Emulator web access behind proxy using HttpURLConnection()
Hi, I'm behind a proxy and have set-up the correct proxy settings in the emulator. I am therefore able to browse the net using the emulator browser. But in my app when using HttpURLConnection to open an input stream to any website I get a connection timeout. This only happens in the emulator, running the app on the device works fine. My question is if the HttpURLConnection uses the same proxy settings as set on the emulator. Or does it access the net some other way? As such it might be blocked by our firewall.

[android-developers] How to show the soft keyboard on native activity
When I try to use ANativeActivity_showSoftInput(), it doesn't bring up the soft keyboard.

I read the source code, and I found after start nativeActivity, NativeContentView(extend View) will be created, and when call ANativeActivity_showSoftInput, it will call showSoftInput() in java side.

I really can't believe I never thought of using a local proxy. It seems all so simple now!

You could have a local proxy in your app that does that for you. I noticed that the API now has an AudioTrack class within android.media. It can take a raw stream of PCM 16 BIT. I was wondering if anyone has any tips or ideas on progmatically transcoding MP3 stream to PCM 16 for playing through. You would have to find an mp3 decoder to include in your app. Using one written in Java would perform poorly, and using a native one would require writing some JNI code and passing data back and forth.

As I haven't really implemented anything with the accelerometer yet, I don't know exactly, but I would go about it by monitoring normal, non-shaking values from the sensor, then anything that fell out of those ranges for a certain amount of time would be considered shaking. my 2 cents.
