What about people all right? I hope so with the whole Stack community.
Well I have a question that is killing me already has time, and I can not solve. First of all I want to remind you that I am a beginner in Android Programming.
I want to put in my App a button or some share menu, so people can share the contents of a webview.
Below is my code:
Android Manifest.xmml
<?xml version="1.0" encoding="utf-8"?>
<android:uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<android:uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
<activity
android:name=".splash_screen"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:noHistory="true"
>
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:configChanges="orientation|screenSize"
android:label="@string/title_activity_splash_screen"
android:screenOrientation="portrait" />
<activity android:name="radardf.radardf.error_webview"></activity>
