when i create a new project in android studio i find the the activity class initially extends AppCompatActivity and i have to change it to extend Activity instead.
but the issue that i am facing is, R class is not recognisable and i receive the error "Cant resolve symbol R". i posted the build.gradle file below and it seems to me it has no errors.
also, after tryin to find out the solution, i checked all the xml files and i found that the style.xml "posted below" has error at "Theme.AppCompat.Light.DarkActionBar" and android studio cant resolve it.
please let me know how to fix this error.
code : public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.xxx.xxx);//cant resolve symbol R
}
}
style.xml :
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">//cant resolve symbol Theme+cant resolve symbol AppCompat
<!-- Customize your theme here. -->
</style>
</resources>
gradle.build :
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.example.com.bt_11"
minSdkVersion 19
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.+'
}
You will have to change the theme to Holo Light or Holo Dark or Material theme as pasted below;
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
</resources>
