I m trying to understand the concept of fragment on android. The official pages has some code snippets and a link mentioning the entire source code called FragementLayout.java. However on clicking it , I get redirected to this page
http://developer.android.com/tools/samples/index.html
Which says the source code is available in the samples directory where the sdk has been installed. I tried checking out samples of various different API levels (8, 11, 17) but could not find the source code for fragments tutorial. Does any body know where it is ?
I have that exact file in the samples folder of 13, 14 & 16.
For extra credit, I recommend checking out the Fragments demo of Action Bar Sherlock, since I believe it shows a better way of learning Fragments.
For more discussion about this, check out my question & the related answers:
How many Activities vs Fragments?
You can see that I do not like the pattern in that tutorial, but there is good discussion for both approaches.
Make a new project using
create project from existing sample. Choose maximum target name then Select Sample ApiDemo.
Finish. Now go to ApiDemos->src->com.example.android.apis.app->FragmentLayout.java
.Enjoy
Yes, it seems to be removed from the official Android online documentation.
However, it can be found in the downloadable "Samples for SDK" for each API level.
To download "Samples for SDK", using "Android 4.4.2 (API 19)" as an example:
Open Android SDK Manager (E.g. Eclipse > Window > Android SDK Manager).
Tick "Android 4.4.2 (API 19)" > "Samples For SDK".
Install.
FragmentLayout.java will be found in a directory like
"C:\Program Files\Android\sdk\samples\android-19\legacy\ApiDemos\src\com\example\android\apis\app\FragmentLayout.java"
You can find the Sample code as well as explanation in official Android Docs
Here
Just clic on this link to download the example from Android Developers wbesite : FragmentBasics.zip

I am trying to use a color picker in Android Studio. There is no color picker in the palette box. However, from online research, there is a color picker in what has been dubbed as the API Demos.
Mac-mini-3:android-24 myuser$ pwd
/Applications/android-sdk-macosx/platforms/android-24
Mac-mini-3:android-24 myuser$ ls
android-stubs-src.jar data package.xml source.properties
android.jar framework.aidl sdk.properties templates
build.prop optional skins uiautomator.jar
But where am I supposed to find the API Demos?
On the Android SDK Manager, I do not see "Samples" mentioned anywhere, as this shows.
For those who come across this answer looking for the old API demos sample, I got it running with Studio, despite some legacy code in the sample:
https://tekeye.uk/android/examples/android-api-demos-for-studio
Regarding The color picker from the old API demos app, it needs a bit of work for todays modern devices. But I sucked the code out of the API demos sample and it can be found here:
https://tekeye.uk/android/examples/ui/android-color-picker-tutorial
It should be installed from the Android SDK Manager by checking the Samples for SDK option.
You can also download them directly from:
android/platform/development/nougat-release/+/samples
https://developer.android.com/samples/index.html
I could not find any Color Picker from the list of samples though.
Here is my repository for Android ApiDemos : https://github.com/av930/ApiDemos
please refer it.
From Android studio 2.2 Preview, Google-provided Android code samples based on the currently highlighted symbol in your project. To use the feature, highlight a Variables, Types and Methods in your code then Right Click to show a context menu for Find Sample Code.

When I tried this future I am getting Samples are currently unavailable for Fragment,AppCompatActivity,Toolbar, FloatingActionButton.
Do we need to download samples or enable it from settings, how can I get this future ?
You need to download samples from the SDK Manager.
Check the following link for reference.

I seem not to be able to find any of the Google Android samples. For example, I'm reading this: https://developer.android.com/guide/topics/graphics/prop-animation.html#keyframes, and there is a link to a MultiPropertyAnimation sample which should show how to use keyframes. When I click there, it get redirected to a samples main page, and the sample I'm looking for is not there, or at least I can't find it. The same for quit a few other samples. I also tried importing the samples in Android Studio, which provides a search/filtering interface, and can't find anything there.
Has Google moved the samples, and forgotten to update the rest of the docs? Did the 'old' samples get deprecated and moved elsewhere? Can they still be accessed?
The latest (and most convenient way) to do it is:
open android studio
if a project is currently opened, close it (file -> close project)
on the following screen choose "Import an Android code sample".
Also see http://developer.android.com/samples/index.html
This is my first post to this group. I am looking at the screenrecord.cpp source code from android.googlesource.com. I found the following source links for the screenrecord.cpp file.
https://android.googlesource.com/platform/frameworks/av/+/android-4.4.2_r1/cmds/screenrecord/screenrecord.cpp
https://android.googlesource.com/platform/frameworks/av/+/aaa3f358410701710e31f31de62f0b4521989661/cmds/screenrecord/screenrecord.cpp
I think, #2 link is the latest source code for screenrecord.cpp. However, how can I know which source code is the latest one?
Any idea would greatly help me.
The answer depends on what you mean by "latest".
The currently-shipping version of Android, "KitKat" 4.4.2, comes with version 1.0 of screenrecord. That's what your first link points to.
The "master" branch of the AOSP source tree has the sources for screenrecord v1.1, which adds some new features. That's your second link. The newer version can be built and run on Android 4.4, but it's not checked into the 4.4 branch, so no devices I'm aware of currently ship with it.
Details about v1.1 are available here.
To see the latest in any git tree, you click on the link higher up the tree.
So for both the link you provided, click on higher up link and you will notice ending up here:
https://android.googlesource.com/platform/frameworks/av/+/master
Within the page is also indicated the latest commit number, and that is the latest as of anytime you are reading this article.
And then travelling down the link to reach the screenrecord.cpp again:
https://android.googlesource.com/platform/frameworks/av/+/master/cmds/screenrecord/screenrecord.cpp
now you notice that this link does not have any version anymore, but is tagged with a commit number - not at the link itself, but the first few lines of the page. That page is also the latest in development right now.
I have downloaded all documentation with SDK manager help. But how can I open this documentation and the samples of code in Android Studio after downloading?
According to Android Studio Tips and Tricks, you can press Ctrl+Q to show docs for selected API under Windows or F1 under Mac.
For the samples , you can use eclipse to export to Android Studio.
First you need to make sure the documentation is added to Android Studio.
Go to File -> Project Structure. Under the Platform Settings heading, add or select an Android Platform. Go to the Documentation Paths tab and make sure the path to your SDK's documenation folder is added there - it should be [SDK]\docs\reference, where [SDK] is the full path to your SDK installation. If it is not there add it manually.
Once this is done, use Ctrl+F1 while your cursor is on the item you want to display help for.
The samples have not been ported to Android Studio yet, but I'm sure google will get around to it at some point. For now follow the instructions in the comments by androidika (you will need a copy of Eclipse installed).
In Android Studio you need to download javadoc dependency which is part of sdk.
If you enable documentation to appear while writing code in android studio by navigating to
File-> Settings-> Editor-> General-> Other
and
selecting(check box) Show Quick documentation on mouse move, you would get irritating after some time because it will come out automatically you when you would be writing code.
So, I think we should go to alternative ways by using Ctrl + Q(on Ubuntu at least I am not sure of other environments). This way when you would feel help you can simply use the simple command.
I was trying to find this setting in the latest build of android studio, and after wasting a lot of time I finally found out that now the ide automatically finds the documentation, which can be opened with shift+f1 on a method.
Now a days once you Import project in Android studio, it will automatically shows docs. But on mouse hover you want to expand it.
Docs hover page was simply resized very short like the above, it looks like docs is not avail. But when I Carefully moving the mouse down to the bottom of the hover page allowed me to resize it.
