我正在尝试在我的活动中添加admob广告但是它显示我的onCreate方法（）在我点击按钮输入下面的活动后出现错误。我特此发布我的代码和Logcat日志，其中引发了错误。清单文件中提供了所有必要的权限。

的build.gradle：

dependencies {
    compile project(':playservicesads921')
    compile 'com.android.support:support-v4:23.4.0'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.google.android.gms:play-services-ads:8.4.0'

}

MainActivity：

    import com.google.android.gms.ads.AdListener;
    import com.google.android.gms.ads.AdRequest;
    import com.google.android.gms.ads.AdView;

    public class Temperature extends Activity implements OnClickListener{

    private AdView mAdView;
    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.temperature);
        Title=(TextView) findViewById(R.id.title);
        Result=(TextView) findViewById(R.id.result);
        Value=(EditText) findViewById(R.id.value);
        spinnerfrom=(Spinner) findViewById(R.id.spinnerfrom);
        spinnerto=(Spinner) findViewById(R.id.spinnerto);
        Calculate=(Button) findViewById(R.id.calculate);
        Bundle b=getIntent().getExtras();
        //Title.setText(b.getString("item"));
        imm=(InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

        mAdView = (AdView) findViewById(R.id.adView);

        AdRequest adRequest = new AdRequest.Builder()
                 .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .addTestDevice("F2B5F7BB75F462E9074A7905A1047616")
                .build();
        mAdView.loadAd(adRequest);
        mAdView.setAdListener(new AdListener() {
            @Override
            public void onAdLoaded() {
            }

            @Override
            public void onAdClosed() {
                Toast.makeText(getApplicationContext(), "Ad is closed!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onAdFailedToLoad(int errorCode) {
                Toast.makeText(getApplicationContext(), "Ad failed to load! error code: " + errorCode, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onAdLeftApplication() {
                Toast.makeText(getApplicationContext(), "Ad left application!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onAdOpened() {
                super.onAdOpened();
            }
Display d=getWindowManager().getDefaultDisplay();
        int h=d.getHeight();
        int w=d.getWidth();
        if(h < 1280 && w < 720)
        {
            Title.setTextSize(15);
            Calculate.setTextSize(15);
        }

        TemperatureItems=getResources().getStringArray(R.array.temperatureitems);
        ArrayAdapter<String> Temperatureadapter=new ArrayAdapter<String>(getBaseContext(), android.R.layout.simple_spinner_dropdown_item, TemperatureItems);
        spinnerfrom.setAdapter(Temperatureadapter);
        spinnerto.setAdapter(Temperatureadapter);

        Calculate.setOnClickListener(this);

//Futher main logic for the code inside onCreate which works perfectly when ads arent added.
        });


    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }

    @Override

        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }

    @Override

        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }
    }
