I am making an android application that needs to display a simple quick search, but to do this i need to change the:
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
To:
<action android:name="android.intent.action.SEARCH" />
<category android:name="android.intent.category.DEFAULT" />
But once I do, the application doesn't find a launcher activity, how can i fix this? This is the code that i am using:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mysoftwaremobileapps.School"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="3" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:label="#string/app_name"
android:name=".SchoolActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
<activity android:name=".GoogleActivity" android:label="#string/app_name"></activity>
<activity android:name=".WikipediaActivity" android:label="#string/app_name"></activity>
<activity android:name=".ProjectsActivity" android:label="#string/app_name"></activity>
<activity android:name=".NotesActivity" android:label="#string/app_name"></activity>
<activity android:name=".SearchFunction" android:label="#string/app_name">
<intent-filter android:label="ACTION_SEARCH"></intent-filter>
</activity>
</application>
There is no reason for a LAUNCHER to exist in a searchable activity.
The point of a searchable activity is that after a search is triggered by the user, your activity then receives the search query, searches your datastore, and finally presents the results.
Now if you wanted a separate activity that does something related to your datastore, for example input or import data, then by all means go ahead and create another activity and assign LAUNCHER to that activity. The searchable activity isn't meant to be a LAUNCHER activity.

In my android app I use a library project and I use one of it's activities. However in the library project that activity has MAIN action and LAUNCHER category intent-filter. So I added that activity to my manifest and removed the intent-filter. The manifests seem to be correctly merged into build/intermediates/manifests/full/debug/AndroidManifest.xml, and the activity looks as expected (without the intent-filter):
<activity
android:name="com.michaelrnovak.util.logger.Logger"
android:configChanges="orientation"
android:label="#string/show_log" >
</activity>
However when I start the app from AndroidStudio in the emulator, then instead of my AlertsActivity, the library's Logger activity is launched. What am I doing wrong?
This is the manifest of the library:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.michaelrnovak.util.logger"
android:versionCode="8"
android:versionName="1.5">
<uses-permission android:name="android.permission.READ_LOGS" />
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity android:name=".Logger"
android:label="#string/app_name"
android:configChanges="orientation">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="7" />
</manifest>
and my app's manifest has the following relevant activity definitions:
<activity
android:name=".AlertsActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/app_name"
android:launchMode="singleTop" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" /> </intent-filter>
</activity>
<activity android:name="com.michaelrnovak.util.logger.Logger"
android:label="#string/show_log"
android:configChanges="orientation"
tools:replace="android:label"
>
<intent-filter tools:node="removeAll" />
</activity>
Have you tried tools:node="remove" on the category node only? From my experience, it seems to work.
Something like this:
<activity android:name="com.michaelrnovak.util.logger.Logger"
android:label="#string/show_log"
android:configChanges="orientation"
tools:replace="android:label"
>
<intent-filter>
<category tools:node="remove" android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
I tried many ways on similar situation like you. I figured out that I must add tools:node="replace" in the Activity node to remove intent-filter's specific action and category. Try this :)
<activity
android:name="com.michaelrnovak.util.logger.Logger"
android:label="#string/show_log"
android:configChanges="orientation"
tools:replace="android:label"
tools:node="replace">
<!-- Rewrite the intent-filter you want -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I'm trying to combine android manifest files from 2 plugins in Unity, but there are two activities with the same intent-filter and I can only get 1 or the other to work at the same time....
Of the 2 conflicting activities, whichever is on top in the manifest file is the one that will work. So if activity from manifest #1 is on top, plugin #1 will work but not #2, and vice versa.
The two conflicting activities are:
<activity
android:name="com.devfo.andutils.DevfoUnityPlayerActivity"
android:label="#string/app_name"
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
And:
<activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity"
android:label="#string/app_name" android:screenOrientation="portrait"
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
is there any way I can merge the two and get them to work from the same app? I'm using Unity 3d.
For example in the manifest where you want to use only the first activity as launcher you have to add this 2 modifications:
At the beginning of the manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
And for the activity for which you want to remove the intent filter add this code:
<activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity"
android:label="#string/app_name" android:screenOrientation="portrait"
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
<intent-filter tools:node="removeAll">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
The important part is to add the tools:node="removeAll" attribute in the intent-filter tag
Declare your manifest header like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
And then add one of the following appropriate attributes to the relevant Activity(s):
tools:merge="override"
tools:merge="remove"
Slightly different to #amarkovits answer, I've found success with:
<activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity"
android:label="#string/app_name" android:screenOrientation="portrait"
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen"
tools:node="merge">
<intent-filter tools:node="remove"> ...
which I believe will try to merge it first, then replaces just the intent filter causing both Icons on the launcher screen
The Activity that has this intent-filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
is the main Activity that will start on application start up, you can't make both activities work at the same time.
what you should do is let only one Activity ( your main one have this filter) and leave the other one without it.
the second Activity will also be part of the application, but it will not be the first Activity you will see. You can start it by using the startActivity() method.
I have done this, the solution is that when you have multiple flavors, like
1. flavorA,
2. flavorB
and main application id is - com.android.vivek
and main flavorA is using com.android.vivek
and second flavorB is using com.android.vivek.flavorb
flavorA's manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.android.vivek">
<application xmlns:tools="http://schemas.android.com/tools"
android:allowBackup="true"
android:icon="#mipmap/flavorA_ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:replace="android:icon" />
<activity
android:name=".ActivitySplash"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait"
tools:node="replace">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
then simply flavorB's manifest mention like below
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.android.vivek">
<application xmlns:tools="http://schemas.android.com/tools"
android:allowBackup="true"
android:icon="#mipmap/flavorB_ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:replace="android:icon" />
<activity
android:name=".flavorB.SecondActivity"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait"
tools:node="replace">
<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>
<activity
android:name=".ActivitySplash"
android:label="#string/app_name"
android:launchMode="singleTop"
android:screenOrientation="portrait">
<intent-filter tools:node="remove">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
when you run flavorA or flavorB then it will work fine
I've been following THIS tutorial to create a Widget with configuration activity. When you add the widget to the homescreen it shows the settings activity and changes the widget look accordingly. But after that you can't change the look.
However I would like for the settings activity to be separate, meaning that there is an icon in the apps menu and when you press it, settings show up and you can change the widget look.
I've tried changing the Main launcher in Android Manifest to the Settings activity, but it doesn't work. How can this be created?
AndroidManifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.wptrafficanalyzer.appwidgetclockconfiguration"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
</intent-filter>
</activity>
<activity android:name=".WidgetConfigurationActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.appwidget.action.APPWIDGET_CONFIGURE"/>
</intent-filter>
</activity>
<receiver android:name="AnalogClockWidgetProvider" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider"
android:resource="#xml/widget_info" />
</receiver>
</application>
Try this, it works for me:
<activity
android:name=".WidgetConfigurationActivity"
android:launchMode="singleTop"
android:excludeFromRecents="true">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
</intent-filter>
</activity>
I have the same problem everyone reports but this began happening suddenly. My app was working as expected, automatically launching the MAIN activity.
But all of the sudden it stopped working and I started seeing the No Launcher activity found! message.
This is my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xitrica.android">
<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk android:minSdkVersion="8" />
<application android:icon="#drawable/icon" android:label="#string/app_name"
android:theme="#style/Theme.Transparent">
<uses-library android:name="com.google.android.maps" android:required="true" />
<activity android:name="ElBusetonActivity" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="andoid.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="RouteInfoActivity"></activity>
<activity android:theme="#android:style/Theme.Translucent.NoTitleBar"
android:name="GetDirectionsActivity"></activity>
<activity android:theme="#android:style/Theme.Dialog"
android:name="PointProviderList"></activity>
</application>
</manifest>
Sorry if I'm not posting this snippet correctly. It's the first time I ever post a question.
Thanks in advance.
<activity android:name=".ElBusetonActivity" android:label="#string/app_name">
try this, prefix (".") on activity name
here (.) refer to package path
Remove
category android:name="android.intent.category.DEFAULT"
as it is not required.
Say if you have the Activity names TestActivity
If you want the TestActivity to be the first to launch when you hit "run", simply add two lines:
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
To the position like below in your AndroidManifest.xml:
<activity
android:name="TestActivity"
android:label="#string/name"
android:screenOrientation="portrait" >
<intent-filter android:label="#string/app_name" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
use the dot before the activities in your manifest to declare it. or you can write the package name dot your activity name.
like this.........
<activity android:name=".ElBusetonActivity" android:label="#string/app_name">
if you not using package name then it decide the default one.
I am trying to develop a basic app to display information in 2 tabs, and from my understanding the info in each tab needs to have its own activity, in addition to the one for the tabs. I have done this, all of the java code looks right, and I have declared all 3 activities in my AndroidManifest.xml. When I launch the app, it crashes on start, and when I run logcat, I find:
java.lang.RuntimeException: Unable to start activity ComponentInfo{android.wingdom.convention/android.wingdom.convention.TabWidget}: android.content.ActivityNotFoundException: Unable to find explicit activity class {android.wingdom.convention/android.wingdom.convention.Schedule}; have you declared this activity in your AndroidManifest.xml?
I keep doublechecking the file, and I dont see anything wrong, it currently looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="android.wingdom.convention"
android:versionCode="1" android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".TabWidget"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<activity android:name=".Map" />
<activity android:name=".Schedule" />
</activity>
</application>
You are defining activities in your activity.
Try the following code instead:
<activity android:name=".TabWidget"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Map" />
<activity android:name=".Schedule" />
