I would like to create a custom way to enter new events to the calendar.
From what I understood it should be easy by creating an app responding to the intent being sent by the calendar app. I created the following activity in my app:
<activity android:name=".Main"
android:label="#string/app_name">
<!-- for normal launch -->
<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.EDIT" />
<category android:name="android.intent.category.ALTERNATIVE" />
<!-- also tried DEFAULT and others -->
<data android:mimeType="vnd.android.cursor.item/event" />
</intent-filter>
</activity>
But still only the builtin dialog pops up. From what I've seen in the sources of the calendar app the Intent isn't hardcoded there.
Am I missing something obvious?
After some more digging in the source code I found out that the intent target class is hardcoded. So no way of overriding the event edit activity. ;-(

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
Best answer: Read through the doc on tasks: https://developer.android.com/guide/components/activities/tasks-and-back-stack
I would like to have two activities. FirstActivity should be started from
launcher (by tapping on icon) and SecondActivity should be started by voice
command (by saying "OK Google, start play example").
The problem is that for my current configuration only FirstActivity is
started. Also method isVoiceInteraction returns false. I also don't see any values in flags that indicates that activity was started by voice.
Here's part of AndroidManifest.xml:
<application android:label="play example">
<activity android:name="com.example.FirstActivity" android:label="play example">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="com.example.EXAMPLE_ACTION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name="com.example.SecondActivity" android:label="play example">
<intent-filter>
<action android:name="com.example.EXAMPLE_ACTION" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.VOICE" />
</intent-filter>
</activity>
</application>
Here it states:
To specify the text to say after "Start", specify a label attribute for the activtiy that you want to start.
But when I change label for SecondActivity it does not help.
I'm using API version 26.
How to setup configuration to handle described behavior?
AFAIK isVoiceInteraction will always return false when the application is opened using "open" voice command. However, the scenario which you described, having another activity to respond to voice commands, should've worked.
The only thing that you might have missed is to put the action android.intent.action.MAIN in the second activity.
I recently started testing my react-native android application and noticed that it doesn't create an app icon on installation. When I debug - it seems to install and run fine, but when I look for it in the app icon to launch - it does not show up. Looking at the list of installed apps, it's there. How can I debug this? Do I need to change the launch mode from singleTop to something else? I tried changing it to singleInstance and it still had the same issue. If I remove some of the intent filters it seems to work - so maybe I messed up the branch.io installation instructions? Do I need to create a seperate intent filter xml node for the other intents? https://dev.branch.io/getting-started/sdk-integration-guide/guide/react/#android-configure-manifest
AndroidManifest.xml
<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:screenOrientation="portrait"
android:launchMode="singleTop"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http"
android:host="www.foo.com"
android:pathPrefix="/event" />
<!-- note that the leading "/" is required for pathPrefix-->
<data android:scheme="fooapp" android:host="open" />
</intent-filter>
<intent-filter>
<action android:name="fcm.ACTION.EVENT" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Update
Splitting up the intent-filters seems to have fixed it - but a bit unclear if that is the correct thing to do. In the branch.io instructions - did they mean for me to create a new intent-filter and not add to the existing main one?
<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="http"
android:host="www.foo.com"
android:pathPrefix="/event" />
<!-- note that the leading "/" is required for pathPrefix-->
<data android:scheme="fooapp" android:host="open" />
</intent-filter>
The launcher is typically specific software developed by the individual hardware manufacturers. On all of the devices i have, an app does not get installed on the homescreen when it is not installed from the play store, but it does show up in the list of apps. However, that behaviour will be specific to the launcher you are using i think.
You should not need to go to settings->apps though just to see it. Is that the problem you are having?
Perhaps a screenshot as well as a description of your test device (s) would make the question clearer.
Update....
Typically the startup activity has one intent filter with only MAIN and LAUNCHER. I would just try to remove the other things from that intent filter and see if that resolves the problem. Then one by one, add the rest of the things you have listed until you identify the problem child.
Looking at this again, I am not sure that you can define 2 actions in a single event filter. So it seems you need to remove VIEW.
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"

How to make my Android app appear in the share list of another specific app
(8 answers)
Closed 9 years ago.
Ok, this is hard to explain, but this is what I don't know how to do:
Basically when you highlight text in Android, you are then given the option to share that piece of text. Therefore you just click on the share button in the menubar.
Now, how can make my app appear in that list of app which can be used to share the text?
Create a activity YourActivtiy and register in manifest with action SEND mime type text/plan even you can handle image type as well by adding another intent filter.
<activity android:name=".YourActivity" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
Just add the following Intent Filter to an activity in your AndroidManifest.xml:
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="yourmimehere"/>
</intent-filter>
You have to write this your manifest file
<activity android:name=".SomeActivity" >
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="tsome mime here" />
</intent-filter>
