Android pinch-zoom into image

I am trying to display an image and pinch-zoom into the image. There doesn't seem to be any built in thing for this. I saw that there are some libraries, but would much rather not use a library for this.
Anyone have an idea on how to do this?

You should refer this answer which uses this library. And also refer the library by Chrisbanes. This is the best place for beginner tutorial

How to apply different live effects to android Camera?

I want to develop a Camera 2 kind of application. So i just wanted to know how to apply live effects to android Camera .Is there any android library for that? plz help me to solve the issue.
thanks in advance....

What have you tried? I assume by live effects you mean shown on the preview.
You can try what the answer here suggested, but any sort of complicated filter implemented in java is going to slow things down. For good performance you'll probably have to write some native code to process the previews. The good news is, if you're writing NDK code you can make use of libraries like OpenCV to do the filtering for you.

Building animation in Android app

I have done apps which uses only pictures and sound clips. What I want to do is to build an Android app which involves animation. I have seen many of the "Water effect" apps in play store, which has quite good animation effect. One of my them is "Koi Pond". I would like to do the similar kind of app for sand. The detailing of the animation should look good as we see and touch the real sand.
I'm new to animation stuff and have no idea about it. Can anyone please help me out with how to use the detailed animation for Android? I know that it is not possible only with java. Please refer me to any blogs/docs available on this stuff.
Thanx

For such effects (as used in Koi Pond) you will need several pixel shaders. To use it you will need to us OpenGL ES 2.0. I would recommend using a game engine like AndEngine for the basic setup and the shader usage. If you have no experience with shaders it won't be that easy!
I'm not sure if AndEngine is the best choice for that, but it is possible with it.
Check it out http://www.andengine.org/
There are also a couple of shader tutorials in the forum

At first for translate or some other simple animation you can use android native animation method , but for great things you can use , this , I think it's all you want ;)

How to use Flipboard effect on Android

I really like some effects in iPad. Especial flipboard, but I am an android developer at the moment, so I want to build an app which has the same effect. But I cannot find any source code about it on the Internet. On youtube I found a video I really like. Can someone help me?

Hey… Here is a quick guide for getting the clipboard effect on your Android phone. Just go through this tutorial for getting it. Hope it will be helpful to you.

http://openaphid.github.com/blog/2012/07/27/how-to-handle-touch-events-for-flip-animation/ there u go, but it is on opengl, and i'm not sure if it supports complex views as ListView. If you want to make one from the scratch i also recommend you this link. It is on Flex, but the principle is similar. http://oreilly.com/pub/a/javascript/archive/flashhacks.html?page=1

Android: Is that possible to implement a flip/page curl from top to bottom like iphone?

I am implementing an app in which i need to flip/pagecurl a pageview? how can i do that? I didnot find a solution for this. I searched a lot in google? Can any one help me on this?

Three possibilities I can think of.
You can implement it using cocos2d-x. There are a lot of scene's transitions which also contains the page curl animation you describe.
There is an open source project called android_page_curl which does this.
Depending on the android versions you are supporting, you can try RenderScript to create that animation.
