Вот файл манифеста:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp.myappandroid">
<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">
<activity
android:label="List of Mobile OS"
android:name=".LoginActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".SettingsActivity" />
</application>
</manifest>
Пытаюсь передавать параметры из одной в другую. Перед отправкой проверяю дебагером - в обоих случаях intent в Extras содержат введённые значения. На приёмном конце проверяю - Extras в обоих случаях пустые. Т.е не содержит пустые значения с указанными именами, а пустой, от слова "вообще".
В чём может быть дело? Что делаю не так? Где смотреть? Куда копать?
P.S. Не знаю, насколько это важно, но LoginActivity изначально была google LoginActivity, я убрал всё, кроме полей ввода данных.
