I am trying to set up a mobile website that opens my mobile app when a link is clicked in the Android browser. To accomplish this task, I added an intent filter to AndroidManifest.xml, as seen in the code below:
<activity android:name=".MyAppActivity" android:label="#string/app_name" android:theme="#style/Theme.Titanium" android:configChanges="keyboardHidden|orientation" android:alwaysRetainTaskState="true" android:launchMode="singleInstance">
<intent-filter>
<data android:scheme="myapp" android:host="app"/>
<action android:name="android.intent.action.MAIN"/>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.LAUNCHER"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>
</activity>
The link itself in the browser works great, and I'm easily able to gather parameters when the app is first opened using Ti.Android.currentActivity. The problem comes when the app is already open, but a user clicks the link to open it from within the mobile browser. When my app opens, instead of resuming where I left off before, I simply see the splashscreen. This goes both ways: If I opened the app first from the mobile browser, then tried to resume it later from the Android homescreen or app drawer, I only see the splash screen. Per tips I saw on other places of the internet, I tried adding the code below to AndroidManifest.xml (as seen above):
android:alwaysRetainTaskState="true" android:launchMode="singleInstance"
This however, appears to have no effect on anything, and the same problem persists. What am I missing here? Any help would be greatly appreciated.
The way i have done was like this
<android xmlns:android="http://schemas.android.com/apk/res/android">
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="18"/>
<manifest android:installLocation="preferExternal"
android:versionCode="1" android:versionName="1.0">
<uses-permission android:name="android.permission.CALL_PHONE"/>
<application android:label="App Name" android:largeHeap="true">
<activity
android:configChanges="keyboardHidden|orientation|screenSize"
android:label="#string/app_name"
android:launchMode="singleTop"
android:name=".mainActivity" android:theme="#style/Theme.Titanium">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<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="schemaname"/>
</intent-filter>
</activity>
</application>
</manifest>
</android>
and its working fine for me . for Android 4.XX

I've followed the steps in the android documentation Here to implement linking in my application. I dont really need any fancy parameter passing, all I want is when the user clicks a link on the browser that my app opens. All I did was modify my AndroidManifest. Here is the relevant part
<application
android:name=".MainApplication"
android:allowBackup="true"
android:label="#string/app_name"
android:icon="#mipmap/ic_launcher"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter android:label="filter_react_native">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="u2player" android:host="open.my.app" />
</intent-filter>
</activity>
I am using react-native-navigation and trying to browse from either the chrome browser or the native browser to any of u2player:// u2player://open.my.app u2player://open.my.app/ doesn't work. I have also binded the url event from the Linking module but nothing works. I restarted, uninstalled, etc.
Help appreciated
Try using branch. It solves most of the problem that you are facing and it also has a very clean documentation. Please go through and let me know if you have any issues
I have created an android app using android studio. When i run my code on the IDE, its runs as expected on the connected phone. The problem is, it does not leave behind an icon on my phone to use it next time. I will again have to run from android studio to use the app. This was fine initially, i don't realize what made the icon vanish. The app is also present in the settings.
When i go to
Settings->apps
i can very well find my app over there. It is not disabled. I tried uninstalling the app and trying again. It still doesn't give me the icon.
I cleared defaults, forced closed and tried everything possible. Nothing is helping me.
Please help.

You should specify a different for every intent that can launch your app. So one for the BROWSER category with your url data, and one for the LAUNCHER category.
From the App Manifest Guide.
Components advertise their capabilities — the kinds of intents they can respond to — through intent filters. Since the Android system must learn which intents a component can handle before it launches the component, intent filters are specified in the manifest as elements. A component may have any number of filters, each one describing a different capability.
Your code would become something like:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<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:host="www.chillumapp.com"
android:pathPrefix="/chillum"
android:scheme="http" />
</intent-filter>
I have created app to act like an home launcher. So when user clicks on the home button I get Complete action using Launcher or my app's name say for example "myhomelauncher".
When I click on home button and click myhomelauncher my application loads everything from first perfectly fine. Now when I am in the second screen in my application say I am looking at activity 2 in my app and now I click on Home button and click myhomelauncher I endup getting the same activity 2 windows it is not reloading. (It should reload and show up activity 1 rather than 2)
I have seen lot of apps that can reload everytime I click their launcher. Why not mine?
Here is what I have done in my manifest.xml
<activity
android:name=".MyLauncher"
android:label="#string/app_name"
android:persistent="true"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I am not sure where is the mistake?
Please have a look into the documentation - what can be of interest to your problem are the following settings:
android:clearTaskOnLaunch
android:launchMode
I would suspect setting android:launchMode to singleTask could solve your problem, altough be careful which side effects this will cause.
So:
<activity
android:name=".MyLauncher"
android:label="#string/app_name"
android:persistent="true"
android:screenOrientation="landscape"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
should do the trick.
Look up launchMode. But be careful, with great power, comes great responsibility.
This is the relevant section in a menifest that seems to work for me. Note that I have put singleInstance in the launch mode because I don't want more than one of my app, ever.
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".usbEffects"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden"
android:screenOrientation="portrait"
android:launchMode="singleInstance"
android:configChanges="keyboardHidden|orientation"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
My application is never shown in the RECENT APPS list whenever I put the following piece of code in my activity's manifest entry
<category android:name="android.intent.category.DEFAULT" />
If I remove above line it works fine. I've also made sure that the following flags are set to false-
android:noHistory="false"
android:excludeFromRecents="false"
But still its never displayed even if I launch app manually.
In case anybody wants to have a look the manifest, its-
<?xml version="1.0" encoding="UTF-8"?>
<uses-sdk android:minSdkVersion="8" />
<application
android:name="com.raj.poc.copypaste.MainApplication"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".CopyPasteActivity"
android:launchMode="singleTop"
android:noHistory="false"
android:excludeFromRecents="false"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.SEARCH_LONG_PRESS" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
It may also happen if you set
<activity... android:label=""/>
for your main Activity
This is the only activity in your application, right?
You are using the category tag twice. You have written in your code
<category android:name="android.intent.category.LAUNCHER" />
so you have already selected the category. When you add a new activity then you will write the Default category tag.
I'm building a time logging application and i have created the main layout.
I tried to debug my application on my phone Samsung Galaxy S and it starts fine, but if i close it and want to run it again it's not in my app drawer. It shows up in Settings->Programs->Manage and in Recent when holding down the home button.
Here is the manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.doweb.timelog" android:versionCode="1">
<application android:icon="#drawable/icon" android:label="#string/app_name" android:theme="#android:style/Theme.NoTitleBar">
<activity android:name="MainActivity" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN">
<category android:name="android.intent.category.LAUNCHER">
</category></action></intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8">
</uses-sdk>
</manifest>
I think your closing </action> tag in the intent-filter is in the wrong position.
Should look like:
<intent-filter>
<action android:name="android.intent.action.MAIN" > </action>
<category android:name="android.intent.category.LAUNCHER"> </category>
</intent-filter>
That filter is a signal to the system that this activity should be visible in the app-drawer. When it's not correct or present, the activity won't be visible.
Usually it's best to use closed empty elements to prevent this error:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
You're also missing a . in front of your activitys class. This always relates to your apps package name. It will internally be joined to packagename + classname. Therefore the dot, otherwise it would result in com.doweb.timelogMainActivity, which is obviously not the correct reference. So it should be android:name=".MainActivity".
your activity's name like this android:name=".MainActivity", you can have a try
