Actually it is very difficult and messy to use extra support libraries, You are getting those errors, because you are using support library's theme which is not a part of android.jar, Instead you can use android.jar's default theme. Just put

public  class MainActivity extends Activity {...}

in place of

public  class MainActivity extends AppCompatActivity {...}

and change your manifest's App theme pointing to 'styes.xml', So basically you have to change the styles XML file to this one

Also you should use below code in 'Manifest.xml' file to point the Theme of your project or Activity in Styles XML file under values

android:theme="@style/AppTheme"

this reference article is very helpful for what exactly you are trying to dohttps://geosoft.no/development/android.html, Also sign your APK in order to run your app on device, otherwise it can show error while installing. Thanks.
