Answer 1

try using this code in the manifest.xml inside the application tag.

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Answer 2

Below I'm listing possible solutions, try this steps one by one:

• 1 Delete app on device and Clean Project

---

• 2 Disable minifyEnabled in debug mode

go to build.gradle(Module: app) in debug block and disable minifyEnabled:

buildTypes {

    debug {
        minifyEnabled false

     }
}

• 3 Setting dataBinding to true in application's gradle file

In my case, I was including another layout <include layout="@layout/attached_layout" /> to my activity's layout and this solved it.

    android {
    ...
    ...
    ...

    dataBinding {
        enabled = true
    }

    }

• 4 Check the relative path of your activities in manifest

eg:

<activity android:name="com.pathToClass.MyActivity"

---

• 5 Check the package names in your custom views

  <com.pathToClass.MyCustomView
      android:id="@+id/myview"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginLeft="16dp"
      android:layout_marginRight="16dp" />

• 6 Try disabling pre-dexing in the app build.gradle:

  dexOptions {
   preDexLibraries false
  }
  

---

• 7 Disable Instant Run

  Go to File -> Settings -> Build,Execution, Deployment -> Instant Run -> Uncheck the checkbox for instant run

---

• 8 Try MultiDexApplication

Add this to build.gradle(Module:app)

android { 

defaultConfig {
      ...
      multiDexEnabled true
}

dependencies {
     ... 
    implementation 'androidx.multidex:multidex:2.0.1'
}


}

if you are using application class you have to extend it with MultiDexApplication instead of Application and add it to AndroidManifest.xml

<application
    android:name="com.myPackageName.MyApplication"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name">

else add MultiDexApplication class path from library as name

<application
    android:name="androidx.multidex.MultiDexApplication"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name">

• 9 Proguard obfuscation

Looks like the class is loaded by reflection, but your proguard file doesn't prevent that class from being obfuscated
