Answer 1

In some cases, this could be a MultiDex issue. Try this in your application class. That is in App.java which extends Application:

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this); // this is the key code
}

Answer 2

if you already added multidex in both gradle and manifest then try to disable instant run and then create apk to test, i was facing same issue and searched a lot and tried every solution but at last this solved my problem

Answer 3

In Android 9 likely to help adding to manifest into "application" tag:

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

Answer 4

add this to gradle.build:

defaultConfig {
...
minSdkVersion 14
targetSdkVersion // your version 
...

// Enabling multidex support.
multiDexEnabled true
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}
