My question is almost exactly this question:
Clone textview to append it to a ViewGroup
However, I was inflating a view, and then attempting to clone it at the object level for performance reasons (I don't want to parse XML every single time), so that answer doesn't help me. View.clone() is protected and it apparently doesn't have a copy constructor. Is there any way to do this?
I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

Is there any way for an ordinary application to replace low level classes that are preloaded on startup, so that higher level preloaded classes will end up calling my custom versions rather than the originals?
I'm thinking the answer is no, but want to make sure I haven't overlooked something.
When start the activity i will set the activity object to the Application, and i will registry it in the Appication app = MyApplication.getApplication(this);

View 2 Replies View RelatedIs there a way to manage the audio levels through an app? Or is it more dependent on the phone's built in capabilities? Right now at work I listen to a skype audio call from my house (for security) at a very low volume and then at a higher level I listen to music or podcasts, both sources going at the same time. When my dog goes nuts, the door is knocked on, or (in theory) if someone busted down my door, I notice the change in volume and sound, turn off my local media, and focus on what I'm hearing until the drama passes.
I ask because I would like to continue this setup when not at work, like say while running, where I again have earphones in and am normally listening to audio content. I would like to be able to have two pieces of audio: music combined with a skype stream or normal phone call, going at the same time like at work. So is there a way to have two sources going at the same time, with the volume of each independently adjustable? Is this an app thing or a phone thing? Phone will be Sprint Hero.
When I start my application I prompt the user for the password and use it to instantiate my data adapter object that I will need throughout the application. So I store it in Application object. My activity A prompts user for pwd, instantiates data adapter, sticks it to Application object and later starts activity B which in turn starts the built int gallery activity. When fooling around with gallery and capturing pictures for some time coming back to activity B I discover that Application.myDataAdapter is null. I found out that during me playing with camera the Application.onTerminate() method was called. So it seems like Android killed my process and when B was supposed to become visible it started a process again jumping directly to activity B bypassing A? Is that how it works? Should I then never assume that Application.myField will survive? and init it not only when A is started but whenever I discover it is null?

Is it possible to create a lockscreen replacement at the application level that replaces the device's security lock, whether it be PIN, passphrase, pattern or face unlock, or potentially a new method? I know it's possible in the framework level, and have done it before, but I'm just wondering if it's possible to do it at the application level.
So far the few lockscreen replacements that I've tried only implement a slide gesture unlock lockscreen UI, and falls back to the device's security lock after that.
I want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3

Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I have updated my tools to revision 7 and now I can't do a build as it says the API level is obsolete. I can understand warning but it won't build at all. I am using android.bat to generate a build.xml for release versions. So the build.xml gets made from scratch each time. If I switch to --target 8 it builds but I have already released it on the Android Market with 6. Won't this mean that some people that have Android 2.0.1 won't be able to run it?

I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.
As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?

View 2 Replies View RelatedIs there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower?

Is there a way to do this?
