After app installation I can't open it - android

I have created an simple app with a few activities. After successful installation I can't open the app. I can just see it in device's apps.
Yes of course a read all the answers telling "You have to set launcher activity". But I set launcher activity.
Here is AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cz.jacon.davodani"
android:versionCode="0"
android:versionName="0.1">
<application
android:icon="#drawable/logo"
android:label="#string/app_name"
android:theme="#style/Theme">
</application>
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activities.SearchActivity"
android:label="#string/search_activity">
</activity>
<activity
android:name=".activities.CustomerActivity"
android:label="#string/customer_activity">
</activity>
<activity
android:name=".activities.CreditActivity"
android:label="#string/credit_activity">
</activity>
<activity
android:name=".activities.PrintReceiptActivity"
android:label="#string/print_receipt_activity">
</activity>
<activity
android:name=".activities.ProductActivity"
android:label="#string/product_activity">
</activity>
Never before happened to me... Can you give me some advice? Thanks a lot


All your activities are required to be defined within the <application> tag.
<application
android:icon="#drawable/logo"
android:label="#string/app_name"
android:theme="#style/Theme">
<!-- Add activites here -->
</application>


Your manifest should look like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="cz.jacon.davodani"
android:versionCode="0"
android:versionName="0.1">
<application
android:icon="#drawable/logo"
android:label="#string/app_name"
android:theme="#style/Theme">
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
...
...
</application>
</manifest>


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cz.jacon.davodani"
android:versionCode="0"
android:versionName="0.1">
<application
android:icon="#drawable/logo"
android:label="#string/app_name"
android:theme="#style/Theme">
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activities.SearchActivity"
android:label="#string/search_activity">
</activity>
<activity
android:name=".activities.CustomerActivity"
android:label="#string/customer_activity">
</activity>
<activity
android:name=".activities.CreditActivity"
android:label="#string/credit_activity">
</activity>
<activity
android:name=".activities.PrintReceiptActivity"
android:label="#string/print_receipt_activity">
</activity>
<activity
android:name=".activities.ProductActivity"
android:label="#string/product_activity">
</activity>
</application>
</manifest>
try Replacing your manifest with this..


Change your AndroidManifest.xml structure to -
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cz.jacon.davodani"
android:versionCode="0"
android:versionName="0.1">
<application
android:icon="#drawable/logo"
android:label="#string/app_name"
android:theme="#style/Theme">
<activity
android:name=".activities.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activities.SearchActivity"
android:label="#string/search_activity">
</activity>
<activity
android:name=".activities.CustomerActivity"
android:label="#string/customer_activity">
</activity>
<activity
android:name=".activities.CreditActivity"
android:label="#string/credit_activity">
</activity>
<activity
android:name=".activities.PrintReceiptActivity"
android:label="#string/print_receipt_activity">
</activity>
<activity
android:name=".activities.ProductActivity"
android:label="#string/product_activity">
</activity>
</application>
</manifest>
All activities tag must be placed inside <application> tag and it should be placed inside <manifest> tag.

App Icon should be placed in mipmap folder. Move your imagebutton_on in res\mipmap\ and Replace below code from application tag:
android:icon="#drawable/imagebutton_on">
With:
android:icon="#mipmap/imagebutton_on"
And resolve the following issue, as Markus Kauppinen mentioned:
<category android:name="roid.intent.category.LAUNCHER" />
To:
<category android:name="aroid.intent.category.LAUNCHER" />
Hope this helps.

Try by removing following lines from all activity tags
android:icon="#mipmap/imagebutton_on"
Keep it in only application tag.

Cannot change intent filter in android manifest

I have 3 activities in this android studio project. I'm tasked with starting them each separately by moving the intent filter into the activity, however I'm unable to start one of my activities. The same activity doesn't have a /activity> closing tag and I'm not sure why. Any help would be greatly appreciated.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sean.lab1">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".StartActivity">
<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="#string/title_activity_login"
android:theme="#style/AppTheme.NoActionBar" />
<activity android:name=".ListItemsActivity"></activity>
</application>
</manifest>
I am able to move the intent tag to my ListItemsActivity and it will start, but I am not able to move the intent filter tag to my LoginActivity, nor does LoginActivity have a closing </activity> tag.

Here is what you want to do
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".StartActivity">
</activity>
<activity
android:name=".LoginActivity"
android:label="#string/title_activity_login"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ListItemsActivity"></activity>
</application>

Try this.
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".StartActivity"></activity>
<activity
android:name=".LoginActivity"
android:label="#string/title_activity_login"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ListItemsActivity"></activity>
</application>

show 2 apps when debugging in android

When I debug and install app in device, it's show 2 apps install in device (one open with Splashscreen & another open without Splashscreen ) . Guide me, what I'm doing wrong.
here is my manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity

android:label="#string/app_name" >

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

You have two Launcher Activities: MainActivity and SplashScreen. Remove one of those. Try this:
<?xml version="1.0" encoding="utf-8"?>
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
</activity>
</application>

You have two LAUNCHER thats the issue
<category android:name="android.intent.category.LAUNCHER" />
Make it DEFAULT in MainActivity.
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

You have 2 launcher activities, remove intent-filter from one. I think SplashScreen should be launcher activity so remove from MainActivity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Error:Cannot read packageName from app/src/main/AndroidManifest.xml

These are the errors that pop up when running my app for splash screen.
Error:The markup in the document preceding the root element must be well-formed.

First impression is that you manifest file (src/main/AndroidManifest.xml) does not start like follows:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.package.name" >
...
</manifest>
Or it has a invalid format...
Share your manifest file and then, we will be able to see exact error

Answer from here is checking that the applicationId is set in the defaultConfig in build.gradle ,
because the applicationId in build.gradle overrides the package in <manifest>.

Your manifest is wrong, you have duplicate the tag close manifest and some tags have wrong open/close tags.
A simple example could be:
<?xml version="1.0" encoding="utf-8"?>
<manifest>
<application>
<activity>
<intent-filter>
<action />
<category />
<data />
</intent-filter>
<meta-data />
</activity>
<activity-alias>
<intent-filter> . . . </intent-filter>
<meta-data />
</activity-alias>
<service>
<intent-filter> . . . </intent-filter>
<meta-data/>
</service>
<receiver>
<intent-filter> . . . </intent-filter>
<meta-data />
</receiver>
<provider>
<grant-uri-permission />
<meta-data />
<path-permission />
</provider>
<uses-library />
</application>
</manifest>
Check android documentation for more info:
https://developer.android.com/guide/topics/manifest/manifest-intro.html
Check if works this code for you:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.pratyuvamgmail.wilm">
<application
android:allowBackup="true"
