Why does AndroidManifest.xml have invalid targetSdkVersion?

I build an app using android studio 3, but when I want to publish it, market said "Your application must have a valid targetSdkVersion set. To solve this problem, you need to edit your AndroidManifest.xml file and upload again the .apk file."
I thought proguard make this problem so add -keep AndroidManifest.xml to rules. But it doesn't resolve my problem.
could you help me please?
I forgot to say I didn't have targetSdkVersion in my manifest. I added it manually but didn't resolve my problem.
my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ir.farshidete.breathefree">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" /><!--optional-->
<uses-permission android:name="android.permission.VIBRATE" /><!--optional-->
<application
android:name=".G"
android:allowBackup="true"
android:icon="#drawable/icon128"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:theme="#style/AppTheme">
<activity android:name=".Main_Activity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".Relaxing_Activity" />
<activity android:name=".Setting_Activity" />
<activity android:name=".Info_Activity" />
<activity android:name=".Absorption_Activity" />
<activity android:name=".Capacity_Activity" />
<activity android:name=".Control_Activity" />
<activity android:name=".Program_Activity" />
<activity android:name=".Contact_Activity" />
<activity android:name="ir.tapsell.sdk.TapsellAdActivity"
android:configChanges="keyboardHidden|orientation|screenSize" >
</activity>
</application>
</manifest>
my gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "ir.farshidete.breathefree"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
debug {
minifyEnabled false
// Uses new built-in shrinker http://tools.android.com/tech-docs/new-build-system/built-in-shrinker
useProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro'
}
release {
minifyEnabled false
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguardTest-rules.pro'
}
}
}
dependencies {
api(name:'tapsell-sdk-android', ext:'aar')
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Finally I solved it by:
removing:
minSdkVersion 15
targetSdkVersion 28
from gradle.
and adding :
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="26" />
to manifest!
It seems slideme.org isn't up to date...

VM has multidex support, MultiDex support library is disabled

I'm getting the following error.
FATAL EXCEPTION: main

here is my build.gradle,i have enables the multidex in the android part,
apply plugin: 'com.android.application'

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}
and my manifest file is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mycompany.newlogin" >
<uses-permission android:name="android.permission.INTERNET"/>

android:label="#string/title_activity_login" >
</activity>
<activity
android:name=".Register"
android:label="#string/title_activity_register" >
</activity>
</application>
</manifest>

create a class lets name it App and extend from MultiDexApplication like this:
import android.support.multidex.MultiDexApplication;
public class App extends MultiDexApplication {
//you can leave this empty or override methods if you like so the thing is that you need to extend from MultiDexApplication
}
in your manifest add App as your application name just like this
<application
android:name=".App" // <<< this is the important line!
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name">
After adding everything make a clean build and it should work now :).

Override attachBaseContext method in your application class
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}

Code above is updated and still doesn't work.................Let me know what you think

Replace android-L with something else -- 20 or 19 would be likely choices. The "L" Developer Preview will not work on anything but "L"-equipped devices and emulators.
Also, the targetSdkVersion in your build.gradle overrides that which is in your manifest. Replace the targetSdkVersion in your build.gradle to 20.
