How to create a Lottie Alert Dialog in Java

I've tried searching for the Java tutorial regarding creating my LottieAlertDialog, but I can't find any. Everywhere it's in Kotlin, but I need the Java code as my project is in Java.
I've tried creating my LottieAlertDialog in this way:
LottieAlertDialog.Builder alert=new LottieAlertDialog.Builder(context,DialogTypes.TYPE_CUSTOM,
"social.json") //Here social.json is inside assets folder
.setTitle("Social")
.setDescription("social");
alert.build();
But the dialogbox doesn't show, when I run the app. To check whether my alert dialogbox was being created or not I tried testing it by printing the description set in the dialog in a Toast:
Toast.makeText(context,alert.getDescription(),Toast.LENGTH_SHORT).show();
The toast works and its showing "social"! That means the dialog is being created. But unfortunately it doesn't show in my app. What do I do? I've implemented all the dependencies as shown in the below link:
lottiealertdialog

Ok, after much hankering, I finally came to the solution. It's
alert.build().show();

The thing is not related to Kotlin or Java as such, you need to show the dialog once you have built it. So far your code is correct. You just need to show it further like this
LottieAlertDialog.Builder alert = new LottieAlertDialog.Builder(context, DialogTypes.TYPE_CUSTOM,
"social.json")
.setTitle("Social")
.setDescription("Social")
.build()
.show();

Android-Stringbuilder Returns Numeric, Not Alpa

Really new to Java and Android but trying to learn. In process of creating a dialog alert I am using the stringbuilder to put together a message to the user. I am taking several lines of text from my string.xml file that looks like
<string name="lbl_deactivated_error">YOU HAVE BEEN DEACTIVATED</string>
<string name="lbl_notification_line2">Call Customer Service 1–800-xxx-xxxx-/string>
<string name="lbl_notification_line3">Email support#xxxx.com</string>
<string name="lbl_notification_line6">Please Exit By Pressing Home.</string>
My stringbuilder looks like
AlertDialog.Builder dialog = new AlertDialog.Builder(ErrorActivity.this);
dialog.setTitle(lbl_deactivated_error);
alertmessage.append(lbl_notification_line2);
alertmessage.append("\n");
alertmessage.append(lbl_notification_line3);
alertmessage.append("\n");
alertmessage.append(lbl_notification_line6);
dialog.setMessage(alertmessage.toString());
dialog.show();
When executed, the alert shows with the title but the message shows a set of numbers, not the text as shown in the strings.xml. It prints each line of the text with the returns, but I get something like
YOU HAVE BEEN DEACTIVATED
2131099688
2131099688
2131099688
Is there an obvious mistake I am making? Does it have something to do with the hyphens in the phone number maybe?

You need to get the String not the resource ID.
Whenever you build it creates an R file that holds resource IDs (ints) for your resource pointers. You want to use the getString(R.string.lbl_notification_line3) instead.

Android Studio - URL string

So I'm pretty new to the whole Android Studio thing and I've been using the internet to help me with a lot of the things I am doing and needed help on something.
I'm not sure if it's possible to connect this to either a string or an SQL database but I have a Main Layouts with a bunch of buttons that allow me to click on them and choose what external player I would like to use to watch the video. In my MainActivity java class, this is how it finds the button.
case R.id.button3:
intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("http://videoname.mp4"), "video/*");
startActivity(Intent.createChooser(intent, "Choose an External Player"));
break;"
I wanted to know if "http://videoname.mp4" url can be connected to like a string where I can always update or change the URL instead of manually going to find the URL in the MainActivity java and changing it. As of now I have to manually do it but a different way to do it would be helpful.
I'm sorry if it's all confusing, but if you know, please let me know as soon as.
Thank you.

you just need write your string URL :
open your directory folder /res/values/strings.xml -> write your string : <string name="yourStringName>yourStringURL</string>. to use your string do this
getContext().getString(R.string.yourStringName) in fragment
getString(R.string.yourStringName) in Activity
or you can write directly on your code, put your cursor on your string, then press key alt + enter choose extract string resource fill the resource name with your string name
wherever you need to use it, just do point 1 or 2. also in your Intent
hope this help you, never stop learning!

Add it to strings.xml in your project. That is the recommended way of using strings anyway.

How to print Android activity display using cloud print

I am trying to implement Google Cloud Print into an app, following the Integration Guide. I'm trying to keep it basic by just printing out google.com. When clicking the print button I created, it brings up the dialog, but I am getting a FileNotFoundException stating
java.io.FileNotFoundException: No content provider:
http://www.google.com
If I then select a printer and click print, the dialog gives me a "Document Missing" message, which makes sense based on the FileNotFoundException.
I took print_dialog.xml and PrintDialogActivity.java verbatim from the guide. Here is my code calling the activity:
Intent printIntent = new Intent(getActivity(), PrintDialogActivity.class);
Uri docUri = Uri.parse("http://www.google.com");
printIntent.setDataAndType(docUri, "text/html");
printIntent.putExtra("title", "Google");
startActivity(printIntent);
I'm attempting to figure out how to print a web page, but would eventually like to be able to print the activity display.
So my question is: What do I need to do in order to print a webpage or activity display?

Try to add the following to your application manifest
<uses-permission android:name="android.permission.INTERNET" />

Use system PIN dialog in Android application

Background
I am trying to write an application which works like described below.
When user start application it check if user have registered PIN on his device.
If user have registered PIN, application must show button "Continue with PIN".
When user press on button "Continue with PIN" system standard PIN dialog must appears.
User enter his PIN and press "Continue" button.
After System must check if entered PIN is correct or no and continue working.
Searches
I have made some searches and found some articles on stackoverflow and other internet sources which say "There is no way to develop a new custom unlock mechanism on a non-rooted phone." or "I would be surprised if you could, because then you would be probably able to steal the pin code, and I don't think anyone would want that.".
Also I have watched some video tutorials like Tutorial: Android Internals - Building a Custom ROM, Pt. 1 of 2 and Tutorial: Android Internals - Building a Custom ROM, Pt. 2 of 2.
EDITED
I have made some searches today and found a very interesting thing, I think I am on a right way to the solution, and I want to share my ideas with you. So looking in android sources I found an interesting files ChooseLockPassword.java (packages\apps\Settings\src\com\android\settings) and LockPatternUtils.java (*frameworks\base\core\java\com\android\internal\widget*) now I am interest in:
Question
How can I call LockPatternUtils class function from my code ? Or Why I cant see that function in Eclipse ?
Decision
So I think that the only way to get access to the Android system PIN dialog is to root the phone make some changes in the system files and use system PIN dialod
Question
Can somebody provide me useful links about getting access to the system PIN dialog in the rooted phone.
Am I on a right way and can I solve my problem in this way?
If anybody encountered such problem please help me to solve.
Any Solutions?

Okay, I have solved this problem and now I want to share my solution with you.
At first as I told I have android sources so I have made some changes in android sources to get access to the PIN and Pattern dialogs. And here they are:
in ~\AndroidSources\pakages\apps\Settings\AndroidManifest.xml I have changed following lines of code
<activity android:name="ConfirmLockPattern"
android:exported="true"> // This line was added by me.
</activity>
<activity android:name="ConfirmLockPassword"
android:exported="true" // This line was added by me.
android:them="#android:style/Them.NoTitleBar">
</activity>
<activity android:name="ChooseLockPattern"
android:exported="true" // This line was added by me.
android:label="#string/lockpattern_change_lock_pattern_label">
</activity>
This modifications allow me to call "ConfirmLockPattern", "ConfirmLockPassword" and "ChooseLockPattern" activities from my own application. After I compile android Source codes and launch system.img on my emulator.
In my application I have write following functions in order to call "ConfirmLockPattern" or "ChooseLockPattern" activities:
/**
* Show PIN/Password confirmation dialog.
*/
void ShowConfirmLockPINActivity() {
CustomLog.i(TAG, "Show Confirm Lock PIN Activity");
Intent intent = new Intent(Intent.ACTION_RUN);
intent.setComponent(new ComponentName("com.android.settings",
"com.android.settings.ConfirmLockPassword"));
startActivityForResult(intent, mRequestCode);
} /* ShowConfirmLockPINActivity() */
/**
* Show set PIN/Password dialog.
*/
void ShowSetLockPINActivity() {
CustomLog.i(TAG, "Show Set Lock PIN Activity");
Intent intent = new Intent(Intent.ACTION_RUN);
intent.setComponent(new ComponentName("com.android.settings",
"com.android.settings.ChooseLockPassword"));
startActivityForResult(intent, mRequestCode);
} /* ShowSetLockPINActivity() */
/**
* Show Pattern Confirmation dialog.
*/
void ShowSetLockPatternActivity() {
CustomLog.i(TAG, "Show Set Lock Pattern Activity");
Intent intent = new Intent(Intent.ACTION_RUN);
intent.setComponent(new ComponentName("com.android.settings",
"com.android.settings.ConfirmLockPattern"));
startActivityForResult(intent, mRequestCode);
} /* ShowSetLockPatternActivity() */

Here are some considerations regarding your question.
Diving deep into Android's code is not very good idea in this particular case, since verifying PIN code is an important security point and its mechanism must be hidden and well protected to avoid any malicious intentions.
Thus, the actions you want to perform (ask for PIN and then check it against real PIN) are prohibited and would look like an intrusion. So, you shouldn't try to get an access to the storage of user passwords.
It would be more correct to try launching standard PIN screen via some Intent and ask it to make all job for you. However, a brief investigation didn't give me any results in this direction; perhaps, you'll find something.
Modifying the ROM is obviously dead-end - no one will flash the phone to install one app. Requiring rooted phone is a bit better, there are apps that cannot run on non-rooted phone, but still it forwards us back to the point #2 (intrusion).
Users may disable PIN check and there are devices with no SIM.
So, according to the all mentioned I'd suggest you think of different verification method for your app.

Since API level 21 there is KeyguardManager.createConfirmDeviceCredentialIntent that can be used to authenticate current user with the device lock pin.
See the usage example.
