My android app is automatically force closing

Question

I have created an Android App for testing admob ads but when I run it, it force closes. My MainActivity:-

package com.dibdev.bmicalculator;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class BMI_Calculator extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bmi__calculator);
}}

My Manifest. I do not think there is any error here.... :-

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dibdev.bmicalculator"
android:versionCode="1"
android:versionName="1.0" >

    android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

        android:label="@string/app_name" >

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

            android:theme="@android:style/Theme.Translucent" />
    </activity>
</application>

My Layout File. I have included xmlns...... in com.google...... Is it correct?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.dibdev.bmicalculator.BMI_Calculator" >

    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

    android:layout_height="wrap_content"
    ads:adSize="BANNER"
    ads:adUnitId="SAMPLE"
    ads:startOnCreate="True" >
</com.google.android.gms.ads.AdView>

Answer 1

in latest ads sdk you need to add meta tag for gms version with ad declaration in menifest file which you forget to add.

integer value can be differ form your value, you can get it in your log cat while debunging.

  <meta-data
        android:name="com.google.android.gms.version"
        android:value="6111000" />

    <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />

Answer 2

I think you missed the activity closing tag of BMI_Calculator activity in your manifest. If that's not it, please post the stacktrace.
