I am working with Android Studio 1.0 when suddenly, out of the blue I can not run my app on my phone because it is telling me that it can not find the default activity.
Changing the "default activity" to the specific activity I want to launch, ends in the error that apparently the activity I selected is not declared in AndroidManifest.xml.
Which also isn't true, because I did declare it in the .xml, I didn't remove it or add something new, it always has been there and now it doesn't want to work.
Thank you for reading and maybe answering / commenting. :D
Edit: This is my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pack.aproject" >
<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" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SecondPageActivity">
</activity>
</application>
</manifest>
you may need to refresh the IDE's cache.

I want to make register_activity is first run if application open. But, still MainActivity run first. Can anybody help me to fix this.
This is my Manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.client18.dd">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/Theme.AppCompat.DayNight.NoActionBar">
<activity android:name=".register_activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".signup_activity">
</activity>
<activity android:name=".MainActivity">
</activity>
</application>
</manifest>
When I see your Manifest file I can not see any faults. I suggest to do followings.
1) Uninstall app in emulator / device if its exists, and then run application.
or
2) Rebuild project with cleaning ( Build > Clean Project )
P.S.
If you could practice signup_activity > SignupActivity it is nice and best practice.
i had a problem, the Android Studio give me a warning which say:
"The acitivity is not declared in Android Manifest" this appear when i look on the Edit Configuration.
I see in another topic wich says that i have to put in androidManifest.xml
But i already did, and the Android Studio doesnt take it.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.drdower.myapplication" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".AplicacionSencillaInicio"
android:label="#string/app_name"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".AplicacionSencillaResultado"
android:label="#string/app_name"/>
</application>
</manifest>
Which problem could be?
Thank u!
copy the code
delete the activity class
recreate one with same name
paste the code
Place your whole package path
com.example.drdower.myapplication.AplicacionSencillaInicio
Then clean your Project.
Also make sure you passed the correct java file name.
After pausing with work on an Android Studio project for a while, and then coming back and adding it to SVN, I can't get the project to run anymore; it seems to me that the original AndroidManifest.xml was probably lost due to a lack of proper "SVN ignore" rules, and as I created a new Android Studio project on a new machine, updated it from SVN and later commited (and also unfortunately already updated on the other machine I work on), it seems that SVN used the newer manifest file and maybe other files needed for a proper build of the project.
Besides the fact that in the current manifest file, there are several activites missing that I'll have to try to reconstruct there, I now have the problem that I always get the "Default Activity not found" error when trying to build. When I set it to .MainActivity (which is absolutely present in app/src/main/java/com.example.bla.logintest) it says "The activity 'MainActivity' is not declared in AndroidManifest.xml" and thus doesn't compile.
My manifest file now looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bla.logintest" >
<uses-permission android:name="android.permission.READ_PHONE_STATE">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<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" />
</intent-filter>
</activity>
<activity
android:name=".EditDB"
android:label="#string/title_activity_edit_diags"
android:parentActivityName=".MenuActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.bla.logintest.MenuActivity" />
</activity>
<activity
android:name=".EditAnswers"
android:label="#string/title_activity_edit_questions"
android:parentActivityName=".MenuActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.bla.logintest.MenuActivity" />
</activity>
</application>
</uses-permission>
</manifest>
Note: I already tried the solutions in [this similar question][1].
[1]: Default Activity not found in Android Studio "this similar question". Rebuilding and invalidating the cache doesn't get me anywhere. I also added
sourceSets {
main {
manifest.srcFile 'src/main/AndroidManifest.xml'
}
to my build.gradle, and this also didn't change anything.
I am aware that the parent to the other 2 activities is still missing and wanted to work on that problem next, but first wanted to have a working default activity.
Do you have any suggestions what I could try? I'm using Android Studio 1.3.2.
This should solve your problem.
You shouldn't write the tag inside the tag.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.bla.logintest" >
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<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" />
</intent-filter>
</activity>
<activity
android:name=".EditDB"
android:label="#string/title_activity_edit_diags"
android:parentActivityName=".MenuActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.bla.logintest.MenuActivity" />
</activity>
<activity
android:name=".EditAnswers"
android:label="#string/title_activity_edit_questions"
android:parentActivityName=".MenuActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.bla.logintest.MenuActivity" />
</activity>
</application>
</manifest>
Im working with an android application ,even if I change the names of classes at AndroidManifest.xml the application still work and installing on the tablet but the weird thing that even I removed the launcher activity from the manifest I still got it when I run the app the same xml view !!!
As an indication Im using Maven too.
I think the problem comes from Maven
this is my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapps.android"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity android:name="com.myapps.android.project.login.Connection"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.myapps.android.project.login.Connection" >
</activity>
</application>
</manifest>
I tried:
removing the R file
undeploying the application from the device with this comand:
mvn android:undeploy -Pandroid-15 -Dandroid.device=usb
Uninstall the application manually from the device
removing maven android folder from .m2/repository
I still got the same activity while deploying the application to the device
First of all, there is a little problem in your manifest: you are defining the same activity twice:
<!-- First time definition of "com.myapps.android.project.login.Connection" -->
<activity android:name="com.myapps.android.project.login.Connection"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Second definition of "com.myapps.android.project.login.Connection" -->
<activity android:name="com.myapps.android.project.login.Connection" >
you should remove the second one, it doesn't make sense to have a duplicated definition.
Did you change the Connection.java and/or Connection.xml and nothing hapened?
I'm using Eclipse to make an Android app. I've used it before and not had this problem. The console says everything installed ok, so I'm a little confused. I'm not sure what is relevant from logcat, but I can post it if you think that would help.
I've restarted Eclipse, ADB, the emulator, and the Mac several times in various orders and nothing has helped. I know it must be something simple but I haven't played around with this in a few months.
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.hyser.pinpoint"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
</application>
<activity android:name=".pinpoint" android:label="pinpoint">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Your Activity needs to be inside of your application tag in your manifest
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity android:name=".pinpoint" android:label="pinpoint">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
It's a similar issue to this:
Unable to start Service Intent
Your <activity> tag needs to be in the <application> block.
Is it possible your manifest does not refer to any activities? If you install an app with no activities in the manifest you will get this behavior.
