I am new to Android studio from Eclipse and trying to tweek setup. When I add and Activity (blank activity) it generates the java file but it comes up with extends AppCompatActivity which gives errors.Most of my project use ActionBarActivity or Activity. Is there a setting that I need to address to gernerate these files and eliminate errors ?
Here is the file generated by adding a activity
package com.example.jerry.els2015;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class Main2Activity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main2, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Here is the gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.jerry.els2015"
minSdkVersion 19
targetSdkVersion 22
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-v7:22.0.0'
}

Based on whether or not you have a dependency on the support library in your build.gradle, Android Studio will either generate your activity with extends AppCompatActivity
or extends Activity
.

As you might already know, AppCompatActivity
is part of the support library. I wonder if you have the library downloaded. You could open the SDK manager and scroll all the way to the end to make sure you have it:
After that you need to include it as a dependency to the gradle build file for the module (not project). In your build.gradle file you need to add:
compile 'com.android.support:appcompat-v7:22.2.1'

At the left projects pane. you will see a project with the name "support-v7-appcompat" on it. double click that to open it.
