App installing on Cellphone but not showing on screen - android

I am developing an android application using android studio, which has 2 activity so far, LoginActivity and the MainActivity, But when I run the application it installs in my cellphone or virtual machine, but does not appear anywhere. I looked into the installed application and the application is installed. I believe my problem is on the Manifest, but I do not know how to solve it.
The complete code is here on GitHub: https://github.com/SoftwareEngineeringClass/MobileApplication/tree/master/Minerva
and here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<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/AppTheme" >
<activity
android:name=".Minerva"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".LoginActivity"
android:label="#string/app_name" >
<itent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</itent-filter>
</activity>
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name"
android:theme="#android:style/Theme.Translucent.NoTitleBar" />
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id" />
</application>

I believe the first thing I'd do is set a breakpoint at the beginning of the launcher Activity and see if execution gets there or not. No matter what Logcat will tell you something is wrong. You have to run it in debug mode of course. Attach the debugger. If you give me all your code I'd be more than happy to take a look and give you a definitive answer quickly.

Do you know if you require permissions? , maybe it is the problem that not allow you to run. Also if you can share your activity I can help you.

When running my android studio app on my phone, it runs but does not save it on my phone

I have previously ran projects and they not only run but save as apps that I can open again later. Now for some reason this particular projects runs and opens but does not save as an app on my phone.
I'm sure I must be missing some simple setting but I can't find any solutions, any help would be appreciated.
Thanks
edit: I am using a Samsung s10 5g, I am coding in Kotlin, I didn't think these things were relevant because I can run my other projects which were also coded in Kotlin and those will save as normal apps on my phone.

Go to Settings -> apps -> (find the application by name) -> uninstall for all users (Depends upon the device you are using)
Then run your app again via Android Studio in your phone. Check if it helps.

Android Studio: App Installs But Doesn't Open Android 5.0

I've been trying to make an app. I've finished it with no errors, but when I install it on my device I can't open it.
I've searched for the solution on here, but nothing has helped. Most people post their AndroidManifest, so here it is.
<?xml version="1.0" encoding="utf-8"?>
<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"></application>
<activity android:name="Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any help is much appreciated. Thanks!

Android Studio doesn't recognize MainActivity though declared in AndroidManifest.xml

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>

app appears in Manage Applications, but not on the main menu

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.
