When create empty android project with no activity by default, and then add empty activity through android studio GUI, debug is showing error
Waiting for application to come online
Manifest file seems to be fine, what step in app setup might have been missed? When creating project with empty activity by default, there is no error
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:dataExtractionRules="#xml/data_extraction_rules"
android:fullBackupContent="#xml/backup_rules"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.MyApplication"
tools:targetApi="31">
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<meta-data
android:name="android.app.lib_name"
android:value="" />
</activity>
</application>
I tried to compare contents of two new created project, one with manually added mainActivity and another project with empty activity created by default, but it seems no diff
Try to clean project and rebuild it , then try again

INTRO
Greetings, all!
My Android Studio 4.0.1 project refused to build due to not being able to find an AndroidManifest.xml file that's in /main/ where it should be, according to the documentation. Mass replacing the occurrences of "api" with "implementation" or vice versa hasn't helped.
Thus, what other information do you want for clarification, and what should change to ensure this works?
Thankee!

Try to rebuild the project or modify project structure. It happens when something was wrong
I'm a beginner in Android.
Every time when I open class teacher's project to my system it shows this error.
Error running app: Default activity not found.
What should I do to match the same project as my teacher's?
I've tried many solutions.
My Manifest file is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.assigncheckbox">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
maybe it happen because you didn't add this activity to your AndroidManifest.xml
<activity
android:name=".yourActivity"
/>
Im taking the udacity coarse and for some reason android studio wont recognize my MainActivity class. Ive tried cleaning the project, rebuilding and making sure that the names were correct but nothing has solved my problem.
Android Manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="androidedx.example.activitylifecycle">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".Activity1"></activity>
<activity android:name=".Activity2" />
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Found the problem, this package name within the code I had to paste
package com.example.android.cookies;
Im not sure why specifically this caused the problem but atleast I solved it.
I wanted to learn how to make android apps and downloaded android studio.
But when I made my first project and it was trying to sync an error came. This is what it said: A problem occurred configuring project ':app'.
When i went to Android Manifest most of it was red. Does someone know what to do?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

you have error in this line. Try to change abel to label
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.
