I have declared a intent to access another layout on a button click, When it was run I getting following error,
android.content.ActivityNotFoundException: Unable to find explicit activity class xxxxxx; have you declared this activity in your AndroidManifest.xml?
From this I understood that intent need to be declared in android manifest file but I don't know how to declare.
Can anyone explain me how to declare<
Thanks in advance
Siva
you need to declare your activity in android manifest.xml here is an example:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your.package.name">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".Activity1" android:label="#string/app_name"></activity>
<activity android:name=".Activity2"></activity>
</application>
<uses-sdk android:minSdkVersion="4" />
</manifest>
u missed some like .helloListView in manifest, even check for the dot.
<activity android:name=".helloListVeiw"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

I have a problem: I want to start an Activity from another application and for that I did the following:
public void startMyActivity(View view){
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package", "com.package.MyActivity"));
startActivity(intent);
}
But I get the error: Unable to find explicit activity com.package/com.package.MyActivity. Also I declared the MyActivity as activity in the manifest file and I still get the same error. What am I doing wrong? Thanks!
Manifest file of the application A(from which I want to start the activity):
<?xml version="1.0" encoding="utf-8"?>
package="com.example.appA"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
and this is the Manifest file of the application B(which contains the activity that should be started):
<?xml version="1.0" encoding="utf-8"?>
package="com.mypackage.package.appB"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="16" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name="com.package.MyPackage"
android:label="#string/title" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Ok so I found my solution. It is a bit frustrating. So.. I tried all the thinks that you guys suggested(I appreciate that) but nothing worked. So my thoughts guided me to use the adb shell to see how it is my application B named and I found out that it is not only com.package, but it's com.mypackage.package(the name mypackage/pakcage are not relevant, only for example purposes). After that I checked the manifest for the application B and saw that the "package" attribute has as value com.mypackage.package. Thank you again!
my error is
E/AndroidRuntime(11101): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.hellolinear/java.text.Normalizer$Form};
have you declared this activity in your `AndroidManifest.xml`?
but in my manifest code is:
<activity android:name=".Form"
android:label="#string/app_name">
<intent-filter/>
</activity>
can anyone help me?
If non of above works, then
uninstall app from your device
restart eclipse( if you are using it, otherwise other IDE)
clean your project
Check whether the activity is in the root package. Otherwise mention the package path while declaring in manifest file.
<activity
android:name="com.example.smstracking.MainActivity"
>
</activity>
Perhaps you the package name is incorrect? Try specifying the full package name like this:
<activity android:name="com.example.hellolinear.Form"
android:label="#string/app_name">
<intent-filter/>
</activity>
The correct way to this, however, would be to add the package name like this tou your manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hellolinear"
android:versionCode="1"
android:versionName="1.0.0" >
at least one activity must contain with intent filter that contain action as action.MAIN and category as Launcher as per my knowledge.Hope this helps as you haven't provided the intent filter in your manifest.
<activity android:name="your package name.Your Activity Name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Your Package name is not written correctly. Your Code:
<activity
android:name=".Form"
android:label="#string/app_name">
<intent-filter/>
</activity>
Instead of above, write this:
<activity
android:name="your package name.Form" // eg: android:name="com.example.myapp.Form"
android:label="#string/app_name">
<intent-filter/>
</activity>
I was making a simple text field and 'send' button to display whatever the user typed in the text field. The program is completely illustrated in the Android training tutorials by android.com.
Whenever I'm adding the Activity DisplayMessageActivity, I'm getting "Duplicate attribute" as an error. Here's the code:
<application
<activity android.name="DroidStart"/>
<activity
android:name="com.start.droidstart.DisplayMessageActivity"
android:label="#string/title_activity_droid" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Update: I fixed the problems that were pointed out, but I'm still getting the error. Here's my current AndroidMainfest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.start.droidstart"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="DroidStart"
android:name="com.start.droidstart.DisplayMessageActivity"
android:label="#string/title_activity_droid" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The error looks like this
Error parsing XML; duplicate attribute. type Android AAPT problem.
My problem was the tools:replace duplicated.
Fixed easy:
tools:replace="android:label,android:theme">
You have at least two errors:
Be sure to close your <application> tag.
Use android:name, not android.name.
So the first 3 lines should change from:
<application
<activity android.name="DroidStart"/>
to
<application>
<activity android:name="DroidStart"/>
Update:
In your updated code, you have:
<activity
android:name="DroidStart"
android:name="com.start.droidstart.DisplayMessageActivity"
You are using android:name twice, which is why you are getting this error. You should probably change this to:
<activity
android:name=".DisplayMessageActivity"
assuming DisplayMessageActivity is the class name of the Activity you which to refer to.
Last, you forgot your manifest end tag: you should have </manifest> at the very end of your file.
change
android.name
into
android:name
on the first line...
For instantapp project also check that you have
xmlns:android = "http://schemas.android.com/apk/res/android"
in app AndroidManifest.xml in manifest tag.
use
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.start.droidstart"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/title_activity_droid" >
<activity
android:name=".DisplayMessageActivity"
android:label="#string/title_activity_droid" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".DroidStart"/>
</application>
</manifest>
instead of
<application
<activity android.name="DroidStart"/>
you are using "android.name" instead of "android:name" for declaring activity in manifest and also close first application tag as <application>
I recently created a project and added a splash and a main activity. I edited the manifest file and added the splash activity and the main activity in to it. After adding the main activity, it gives me a warning "Exported Activity Does not Require Permission". What is this warning that it gives me? my API version is android:15.
Please help,
Thank you!
this is my manifest file!
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sliit.droidman"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="15" />
<application android:label="#string/app_name"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme">
<activity
android:name=".SplashActivity"
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="com.sliit.droidman.main.MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="com.sliit.droidman.main.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
add this to your activity definition
android:exported="false"
This warning means that your activities are exposed to different-process apps that might instantiate them without any required permission.
for details see:
http://developer.android.com/guide/topics/manifest/activity-element.html
http://developer.android.com/guide/topics/manifest/activity-element.html#prmsn
It could be due to the <action android:name="com.sliit.droidman.main.MAINACTIVITY" />. I don't know why you add that intent filter?
You normally don't need an intent-filter for other normal activities.
My default package name is com.xont.controller (R file contain that package.Eclipse generated one) . I want to make it more packages.Like 'com.xont.controller.salesand 'com.xont.controller.admin like this: And I added activity also in manifestfile
Edited
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.xont.controller"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:label="Xont" android:icon="#drawable/virtusel64">
<activity android:name=".AndroidAppXontActivity"
android:label="Xont">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".LoginActivity"
android:label="Login">
</activity>
<activity android:name=".syn.DatabaseCheckActivity"
android:label="Databse Setup">
</activity>
...........
Package structure is:
Error says : android.content.ActivityNotFoundException: Unable to find explicit activity class {com.xont.controller/com.xont.controller.syn.DatabaseSetupActivity}; have you declared this activity in your AndroidManifest.xml?
Please help me what i want to do here.
All components that are registered as .SomeName use manifest's package value as prefix. So basicaly you regsitered activity .AndroidAppXontActivity as com.android.xont.controller.AndroidAppXontActivity. But there is no such java class.
You should fix your component names to have full name to your Java class, like this:
<activity android:name="com.xont.controller.AndroidAppXontActivity" ... />
Same for all other components.
Please try this,
<activity android:name="com.xont.controller.syn.DatabaseSetupActivity"
android:label="Databse Setup">
</activity>
