Is there any way to disable deep link on Fragment? - android

I implemented an app using NFC which has URL link. So, When NFC is on, the mobile detects URL and opens my app.
I made it happen like this:
<activity
android:name=".view.main.MainActivity"
android:launchMode="singleTop"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED" />
<action android:name="android.nfc.action.TECH_DISCOVERED" />
<!--<action android:name="android.intent.action.MAIN" />-->
<!--<category android:name="android.intent.category.LAUNCHER" />-->
<category android:name="android.intent.category.DEFAULT" />
<data
android:host="example.com"
android:scheme="http" />
</intent-filter>
<meta-data
android:name="android.nfc.action.TECH_DISCOVERED"
android:resource="#xml/nfc_tech_filter" />
</activity>
However, the problem is, I have many activities and fragments. It works even while I use my application and It keeps open my application on each and every activities and fragments.
I don't want this behaviour. I want it detects URL just out of my application. How can I achieve this behaviour?


make it single task to avoid multiple opening of the activity
android:launchMode="singleTask"

When app is sterted, trying to share the text and app is launching but if open pervious app by android navigation button i see 2 my app exemplars. How to check if app is launched and reopen not open second at one time

Simple answer: you need to add
android:launchMode="singleInstance"
within your activity bracket (below android:name=".activitys.SplashScreen", for example)
Better answer: Go through this article to understand the different types of launch modes: https://medium.com/#iammert/android-launchmode-visualized-8843fc833dbe

Background call android

I need to do background calls. I mean, I don't want to show the android call interface when the program makes a call I want to show my own interface, is there any way to do it?
Thank you!

It's not possible at the moment. For phone calls, it will always show the dialer screen.

Though it is not recommended to do, you can achieve that by linking an Activity with the call.
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- open activity when establishing a call -->
<intent-filter>
<action android:name="android.intent.action.CALL_PRIVILEGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
</activity>

Need assistance with the Android Manifest XML File within my Launcher App

Hoping someone can point out my failure here. Ive developed a custom launcher app which I want to replace the home screen. I also want the activity accessible via a custom URL "myapp://launcher.android.com."
I'd love to explain why, but to cut a long story short, the Android Gods demanded that I consolidate two activities (each working fine) into a single Activity.
Can someone check over my manifest file to point out any errors or fields I need to fix? Or even a superior alternative?
<activity
android:name=".KioskLauncher"
android:label="#string/app_name"
android:theme="#android:style/Theme.DeviceDefault.NoActionBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
<intent-filter>
<data android:scheme="myapp" android:host="kiosk.androiddev.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>

You need an extra attribute to be added to the activity tag.
Try adding this to the activity tag:
android:launchMode="singleTask"

Android Intent-Filter for Multi Screen

I want to launch my application from web browser in Android using Intent-Filter based on scheme, host in the DATA tag like this.
<activity android:name=".activity.LogoActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".activity.phone.MainActivityPhone" android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="my" android:host="mystore" />
</intent-filter>
</activity>
<activity android:name=".activity.tablet.MainActivityTablet" android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="my" android:host="mystore" />
</intent-filter>
</activity>
As you see, There are two Main Activities for phone and tablet, and in LogoActivity determine which Main Activity will be opened by screen size. But the problem is when user clicks my://mystore link in web browser, there are two choices to launch that MainActivtyPhone and MainActivityTablet.
What I want is there is only one proper intent-filter works for uri my://mystore .
Any help? Thanks.

On the first run of your application, use PackageManager to disable the activity you do not want to use.
Please do not invent custom schemes. Please use HTTP URLs instead:
<data android:scheme="http" android:host="yourdomain.com" android:path="/something/or/another" />
That way, you can actually put a real Web page at http://yourdomain.com/something/or/another, so if somebody gets your link but does not have your app installed, they will see your Web page, instead of getting an error.
Also, please remove android:configChanges, or handle all configuration changes.

Could not launch application by calling a URL from Android Browser

There are many answers in stackoverflow showing how to lauch app from a web browser ,but I am not sure what went wrong with my code, that never seems to be doing the intended.
I am trying to launch my app by a URL from any other app like web browser,initially
my manifest file looks like this
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
And When I typed http://ebay.com in the browser that never started my app.Obviously,how does the browser know about my app?,then i tried the other way around and added another Activity called MyActivity and altered the manifest file as
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MyActivity">
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
and tried in my Main Activity
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://mycityway.com")));
Thus producing the intended result.I can also start another application Activity using this method.
But most of the answers here says that the later is possible.What is the mistake i am doing,I couldn't launch my app from browser.Please guide me.

And When I typed http://ebay.com in the browser that never started my
app.
It gets started when a matching link is clicked not when you type the url in the browser.
Try it by sending yourself an email containing http://ebay.com and click the link in the email application.
