So I am trying to get ads to work for my first Android ap, I am following the Google developers tutorial found here: https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals
Thus my code looks like what it looks like in the example:
package com.google.example.gms.ads.banner;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.AdView;
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
/**
* A simple {@link Activity} that embeds an AdView.
*/
public class BannerSample extends Activity {
/** The view to show the ad. */
private AdView adView;
/* Your ad unit id. Replace with your actual ad unit id. */
private static final String AD_UNIT_ID = "TO_BE_DISCOVERED_SHORTLY";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create an ad.
adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId(AD_UNIT_ID);
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout);
layout.addView(adView);
// Create an ad request. Check logcat output for the hashed device ID to
// get test ads on a physical device.
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("INSERT_YOUR_HASHED_DEVICE_ID_HERE")
.build();
// Start loading the ad in the background.
adView.loadAd(adRequest);
}
@Override
public void onResume() {
super.onResume();
if (adView != null) {
adView.resume();
}
}
@Override
public void onPause() {
if (adView != null) {
adView.pause();
}
super.onPause();
}
/** Called before the activity is destroyed. */
@Override
public void onDestroy() {
// Destroy the AdView.
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}
}
However, when I compile this I get the following errors:
BannerSample.java:25: error: package R does not exist
setContentView(R.layout.activity_main);
^
BannerSample.java:34: error: package R does not exist
LinearLayout layout = (LinearLayout) findViewById(R.id.linearLayout);
^
2 errors
I suspect the solution to my answers may be incredibly simple, but I'm not sure where these Rs are suppose to come from and the tutorial doesn't say anything about it. Help?
I am compiling using this javac command:
javac -cp ".;android.jar;google-play-services.jar" BannerSample.java
