Hello, this is Chris talking, your fellow Time Keeper (yeah, I was nicknamed) and this is my tutorial on how to build a simple, lightweight analog clock!
______________________________________________________________
This guide assumes that you have successfully set up the Android SDK, ADT, Eclipse, some basic Java knowledge and image editing skills.
_______________________________________________________________
Let's start!
Go to the menu bar and click File > New > Android Project
Give your project a name, such as "XDA Devs Clock". Anything you prefer. This isn't going to affect the final app.
Next, select Android 1.6 as the build target. Analog clocks don't require anything special.
Now it's time to create the package name. I usually make mine like "com.xda.clock.chris".
Untick the "Create Activity" checkbox.
Info: We don't need to create an Activity because we are making a widget. Widgets don't have Activities, otherwise, they would be shown in the app drawer.
Click Finish and Eclipse will set up the project.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
________________________________________________________________
Next up, you need to make 3 images for the clock:
The dial (which is the clock's background)
The hour's hand
The minute's hand
Use your incredible Photoshop/GIMP/Illustrator skills to make your awesome clock!
Few tips:
Make the canvas 300*300 pixels
Make the dial with 10% padding
To easily make the hands, keep the dial background and draw the hour's and minute's hand as they were at position zero (Hour at 12 o'clock and minute at zero). Erase the dial and save each hand image
Save with a .png extension. So, in the end, you will have 3 images. Name them:
hand_dial.png
hand_minute.png
hand_hour.png
All lower case. It is extremely important or else you will get an error!
Also, create an app icon. You need to make 3 different ones for every screen size.
HDPI - 72*72 px
MDPI - 48*48 px
LDPI - 36*36 px
Save them with the name "ic_launcher.png" and overwrite the images that are already in the project's respective folders.
________________________________________________________________
Following, we gotta put them to our app.
So, first, right-click res > New > New folder and name it "drawable".
Drag your images you created previously into there.
Now, let's make the layout of the clock.
Go to res > layout > main.xml
Go to the main.xml tab (at the bottom) and delete the TextView block. Next, change the layout from Linear to Relative.
Now, we will add the clock's code.
Code:
<AnalogClock
android:id="@+id/analogClock1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:dial="@drawable/hand_dial"
android:hand_minute="@drawable/hand_minute"
android:hand_hour="@drawable/hand_hour"/>
So, what did we do there?
We gave the item an id
We put it in the middle of the screen
We redirected the drawables to the respective hand and dial
The final xml is this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<AnalogClock
android:id="@+id/analogClock1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:dial="@drawable/hand_dial"
android:hand_minute="@drawable/hand_minute"
android:hand_hour="@drawable/hand_hour"/>
</RelativeLayout>
_______________________________________________________________
Next, we need to tell Android that what we are actually doing is a widget.
Right click res and create a folder named "xml".
Right clock xml > New > Android XML file
Change the Resource Type to AppWidgetProvider and give it a name such as "widget_config.xml". Lower case!
Delete everything and paste this in:
Code:
<appwidget-provider
xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="140dip"
android:minHeight="140dip"
android:updatePeriodMillis="0"
android:initialLayout="@layout/main"/>
There we set how many rows the widget will take. The calculation method is
74 * [number of rows] - 4
We want the widget to be 2*2 so the width is 146dip and the height is also 146dip. But we'll change it to 140 to make it a little bigger.
Then we set an update period... which actually doesn't work below 30 minutes. It's a bug in Android and last, we gave it a layout, which we made previously (main.xml).
____________________________________________________________
Now, we must declare the widget in the manifest.xml with a <receiver> element.
Open the manifest xml and delete the <activity> block. As said previously, we won't have any activity.
Inside the <application> add this piece of code:
Code:
<receiver android:name=".Clock_Actions" android:label="XDA Analog Clock">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_config" />
</receiver>
The android:name is the class we are going to create in a few minutes.
The label is the name that will be shown in the widget picker of your homescreen. Then we specified the update and linked the widget_config.xml
The final xml is:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xda.clock.chris"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="4" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<receiver android:name=".Clock_Actions" android:label="XDA Analog Clock">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_config" />
</receiver>
</application>
</manifest>
_______________________________________________________________
Now it's time to create the Clock_Actions class.
Right click the package > New > Class
Give it the above name.
Delete everything and paste this in:
Code:
package com.xda.clock.chris;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.widget.RemoteViews;
public class Clock_Actions extends AppWidgetProvider{
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
PendingIntent pendingIntent;
if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
{
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.main);
pendingIntent = PendingIntent.getActivity(context, 0,getAlarmPackage(context), 0);
views.setOnClickPendingIntent(R.id.analogClock1, pendingIntent);
AppWidgetManager
.getInstance(context)
.updateAppWidget(
intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS),
views);
}
}
public Intent getAlarmPackage(Context context)
{
PackageManager packageManager = context.getPackageManager();
Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);
String clockImpls[][] = {
{ "Standard Alarm", "com.android.alarmclock",
"com.android.alarmclock.AlarmClock" },
{ "HTC Alarm ClockDT", "com.htc.android.worldclock",
"com.htc.android.worldclock.WorldClockTabControl" },
{ "Standard Alarm ClockDT", "com.android.deskclock",
"com.android.deskclock.AlarmClock" },
{ "Froyo Nexus Alarm ClockDT",
"com.google.android.deskclock",
"com.android.deskclock.DeskClock" },
{ "Moto Blur Alarm ClockDT",
"com.motorola.blur.alarmclock",
"com.motorola.blur.alarmclock.AlarmClock" },
{ "Samsung Galaxy S", "com.sec.android.app.clockpackage",
"com.sec.android.app.clockpackage.ClockPackage" } };
boolean foundClockImpl = false;
for (int i = 0; i < clockImpls.length; i++)
{
String packageName = clockImpls[i][1];
String className = clockImpls[i][2];
try
{
ComponentName cn = new ComponentName(packageName, className);
packageManager.getActivityInfo(cn,PackageManager.GET_META_DATA);
AlarmClockIntent.setComponent(cn);
foundClockImpl = true;
} catch (NameNotFoundException nf)
{
}
}
if (foundClockImpl)
{
return AlarmClockIntent;
}
else
{
return null;
}
}
}
Change the package name to your own after pasting.
So here, we set up the update, the remote views and the pending intent which redirects you to the Desk Clock app. Because different phones have different Desk Clock package names, we set up a method to handle that.
Many thanks to sndytime. Got the code from his post here.
____________________________________________________________
Next up...nothing! Our clock is done! We just have to export it.
Right click the project > Android tools > Export signed application
Choose next, select Create new keystore > click browse and give it a name.
Create a password and click next.
In alias put whatever you want. I usually put "chris95x8"
Enter your password again and put, like, 100 year for validity. You get the rest.
Click Next, browse and enter a name for the apk.
Click Finish and congrats on your first analog clock! Yay!
If you have done everything right it should work. Otherwise, comment here on the thread.
*Sorry for big images

I hope to see some clock on the Themes & Apps section soon. Good luck everyone!

great tutorial buddy!
getting right to do the job!
I made one sometime ago but all ended when started to add settings
Anything didnt work anymore from then on
Lol interesting, thanks.
Too fun ! Thank you dude !
Great Job Chriss, nice and clear. However I still menaged to get stuck.
Now it's time to create the Clock_Actions class.
Right click the package > New > Class
Click to expand...
Click to collapse
Where/what should I right click?
For now I created in in src folder in (default package), but I get 3 errors, so I assume I did it wrong.
Anyway tutorial looks great

Hi,How to add second to it?
Hello.Thank you for this great tutorial.I'm beginner and i have problem with clock.When i use clock with some of launchers Go Launcher,Apex launcher.. when restert phone i get error-Problem loading widget.Pleace help me.Sorry for my English
so how to add date & weather to it ?
Cant find main xml
First off, wonderful tutorial! Thanks :good:
So, forgive my n00bness please. I've never fully taken on the world of designing apps or widgets so much of this is new to me. I set everything up according to directions but have gotten stuck looking for the main xml file. After an hour or so of looking, and looking... and looking, I CAN NOT for the life of me seem to locate it anywhere. I have downloaded the most recent ADT package ( build: v21.0.0-519525 ) and it's running Eclipse 3.8. I've included a screenshot. Not sure if I've done something wrong or what, but I'm guessing it's most likely in plain sight. I am just not sure where to begin to look! Any help would be awesome, I have a slew of custom new clocks I feel the Android community would love :fingers-crossed:
EDIT: I've gone through and manually added an Android XML Layout file to the layout folder with the name of main.xml. After doing this I've gone through and followed step by step everything to the T. Everything checks out in the end after exporting, and even installs correctly. However, it does not show up in my widgets list or App drawer, and when trying to launch it from a file manager it says it cannot be launched.
Help!

Hi, i'm wondering where i can read more about /system/media/lockstyle file structure and coding language. Yeah, i know that manifest is an XML file, but if we for example have this code:
Code:
<Var name="isreached_to_pressed" expression="1" const="true"/>
<Var name="lock_state_pressed" expression="eq(#unlocker_lock.state,1)+eq(#unlocker_call.state,1)+eq(#unlocker_mess.state,1)"/>
<Var name="lock_state_normal" expression="eq(#unlocker_lock.state,0)*eq(#unlocker_call.state,0)*eq(#unlocker_mess.state,0)"/>
<Var name="lockstate" expression="#unlocker_lock.state+#unlocker_call.state+#unlocker_mess.state"/>
<VariableCommand name="camera_show_ani_end" expression="ifelse(#leftToRight,#screen_width-abs(#touch_dist),abs(#touch_dist)-#screen_width)" const="true" condition="#camera_show_ani_con"/>
Where do i get more information about all this eq, abs, ifelse expression, and Var names like lock_state_pressed, lock_state_normal, camera_show_ani_end etc. Is there any guide out there, i wasn't able to find by myself.
Oh, one more thing.
Does the lockstyle file only describes the outlook of lock screen or does it also handle the actions like how to unblock (press, swap or tap)?
I am attempting to replace the data an app* stores in an XML resource, and I can't figure out how to make it work. I followed the tutorial, but it only covers things like "drawable" (and the simple types like string and integer)
I have tried various combinations of compiled or textual XML, with the file in res/xml or res/raw, and so far have not found anything that had any effect on the app, while my module never reports any errors! (at least not in any log I've found)
*The app is Swype, I'm attempting to replace one of the English keyboard layouts (qwerty, azerty, or qwertz) with a completely new one I saw that's actually good for the sliding entry method instead of a slide left on the top row being at least 14 different possible words (Seriously, I made a list) including some very commonly needed ones like it, or, out, and our. The layouts are** stored in xml files such as res/xml/kbd_azerty_panlatin.xml but even attempting a single letter swap hasn't done anything yet.
So, what do I need to do to make a line like
Code:
resParam.res.setReplacement(resParam.packageName, "xml", "kbd_azerty_panlatin", xrf);
actually work? (xrf is from
Code:
XResForwarder xrf = modRes.fwd(R.raw.kbd_azerty_panlatin);
as of my last attempt. modRes is as per the tutorial) and that file is in the last attempt compiled by creating a new Swype apk with the modification via apktool then just grabbing it from there.)
**Note that actually attempting to run recompiled Swype APKs -- modded or not -- fails with a crash when the keyboard would appear, so I can't actually confirm that I'm right about the location of the layouts I need to change, but it seems to be reasonable that they are where I think. I also have No idea how to link them to the language options, so I can't see a way to create a new one instead of replacing an existing.
bump, I'm curious too
edit: if you scroll down on the tutroial page, it covers modifying xml layouts

It doesn't give much detail and since layouts are a separate type, it might not apply anyway.
I really hope it's not right about me needing to include All the xml files in the app just to make one work. I suppose I should try it anyway.
ok i was able to successfully replace an xml file in snapchat using xposed, although it caused snapchat to fc, but i think thats on the app itself. i basically copied the code on the tutorial word for word lol
Code:
package com.joss.geofilter;
import android.content.res.XModuleResources;
import de.robv.android.xposed.IXposedHookInitPackageResources;

}
because i put it in /raw, i had to compile the xml first using apktool and swap it into the xposed module using 7zip afterwards
I'm late, but i think you've misunderstand some things. For example, you can't mod Swype, not like you do here.
I give you an example. I've this xml file:
Code:
<resources>
<color name="white">#ff000000</color>
<color name="common_signin_btn_default_background">#ff000000</color>
</resources>
(taken from Twitter app)
I want to change that values. You can't replace the entire xml, but you can create an xml, name it like you want (xda.xml will work) and put in it:
Code:
<resources>
<color name="white">THE COLOR YOU WANT</color>
<color name="common_signin_btn_default_background">THE OTHER COLOR YOU WANT</color>
</resources>
and you put that file into res/values of your Xposed app. You've not to write all entries, you write only those you want to change. Now, you have to write the code that does the magic:
Code:
import android.content.res.XModuleResources;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
public class Main implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
private static String MODULE_PATH = null;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
if (!resparam.packageName.equals("com.twitter.android"))
return;
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, resparam.res);
resparam.res.setReplacement("com.twitter.android", "color", "white", modRes.fwd(R.color.white));
resparam.res.setReplacement("com.twitter.android", "color", "faint_transparent_white", modRes.fwd(R.color.faint_transparent_white));
}
}
So, into 'resparam.res.setReplacement' you don't put the xml name, but you put the resource name. In this case, the color's name. So, if in your xml you have:
Code:
<resources>
<color name="forum">THE COLOR YOU WANT</color>
</resources>
you will use:
Code:
resparam.res.setReplacement("com.twitter.android", "color", "white", modRes.fwd(R.color.forum));
And that changes the color 'white' of Twitter app, into the color 'forum', that you've defined into your xlm xda.xml ('THE COLOR YOU WANT' here).
For layout, that is a bit different...
Ok sorry, my last post here is not totally correct. The way used in the first post should work, but it doesn't. Has someone find a solution?
P.S. The example of snapchat is a bit different, probably, because it uses 'layout'.
P.S.2 This thread should be moved in the 'Xposed' section...

Oww. I am actually getting started with android development and i am also learning how the system itself works. However i haven't found an example to edit a string resource in an app. I only find examples on how to edit systemui resources. Any help with finding that?

Note that this 'replacement' only works with the Xposed framework.

actually i meant over writing. Like changing string values
I am following geeksforgeeks app building tutorial. Totally new to building apps with android studio and I have hit a couple of snags which I solved.
I have got to the point where I now have a working json URL and the next step is to gue the URL to get the data in to the app and to copy & paste code in to app>res>layout>activity_main.hml file.
I do not know where to put the URL and the code and when I try it does not work.
This is the working json call
https://spreadsheets.google.com/feeds/cells/1puaF3Z9eJxlnyW1-sjwHZlJah9DXmY18Ol2i6S3Drr4/1/public/full?alt=json
Text saying what to do
After copying this id paste the id in the below URL and run the URL in your browser. You will get to see all the excel data in JSON format. Now we will use this data in JSON format inside our app. Make sure that you have published your Excel sheet. Otherwise, this method will not work. Now we will use this URL in our app to get the data in JSON format.
Which now works in browser (their example did not)
Then I am supposed to do this
Step 5: Working with the activity_main.xml file
Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.
XML
<?xml version="1.0" encoding="utf-8"?>
<!--in this we are displaying a nested scroll view-->
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/idNestedSV"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!--recycler view for displaying our list of data
and we are making nested scroll for our
recycler view as false-->
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/idRVUsers"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:listitem="@Layout/user_rv_item" />
<!--we are adding progress bar for thepurpose of loading-->
<ProgressBar
android:id="@+id/idPBLoading"
android:layout_width="wrap_content"
android:layout_centerInParent="true"
android:layout_height="wrap_content" />
</RelativeLayout>
I think the URL has to be in somewhere for the above to work.
can anyone help?
I may have figured out what I was doing wrong with the code but the emulator is just sitting there spinning as if wait for the data in json format.
The only thing that I may not be doing right is I have not added the URL, I think I have all the parts added other than that but the error suggests to me that the class UserModal is empty. error reports all point to UserModal which is there and as I understand it is used to store the json format data.
I think I found the correct place to put the URL but the app will not run in the emulator.
The app I'm working with is found here

I'm still struggling with these errors, as this code is copied & pasted as per the instructions in the tutorial unless AS has changed and some of the commands are not in the newer version then I would expect the code is correct and it is something I have done wrong.
I have attached a PDF of the tutorial. Can anyone give me some help?
