Google maps activity crashes after successful installation

Not sure why this is happening, the application shows no errors and I've obtained the key successfully as well but the activity doesn't run!
Here is my MapScreen class:
package com.example.prateekchachra.projectconnecttoastmasters;

return;
}
googleMap.setMyLocationEnabled(true);
googleMap.setTrafficEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(true);
Marker marker = googleMap.addMarker(new MarkerOptions().position(Pos).title("That is my loc"));

Change your android :name in your XML file
android:name="com.google.android.gms.maps.SupportMapFragment"
Replace with your Fragment package and fragment name like
android:name="com.example.prateekchachra.projectconnecttoastmasters.MapScreen"

Force Close on replacing AppCompatActivity with Activity

I had an old project in Eclipse and I imported it into Android Studio to rebuild it with Material Design.
I done all things...
configured build.gradle and dependencies:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.mhrz.Minesweeper"
minSdkVersion 8
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.android.support:cardview-v7:+'
}
and styles:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#1E9618</item>
<item name="colorPrimaryDark">#146310</item>
<item name="colorAccent">#1E9618</item>
</style>
</resources>
and this is Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mhrz.Minesweeper"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".MinesweeperGame"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and also CardView works well.
The problem is that app works correctly with this and give me Holo Design:
public class MinesweeperGame extends Activity {
but I want Material and I get FC on:
public class MinesweeperGame extends AppCompatActivity {
with this log:

Where is mistake? How to fix it?

Android system doesn't know that you want to use alternate theme for application (like yours AppTheme) until you define it in application or activity attribute inside AndroidManifest.xml file.
You need to add the android:theme="#style/AppTheme" attribute to your <application> tag in AndroidManifest.xml like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mhrz.Minesweeper"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#style/AppTheme">
<activity android:name=".MinesweeperGame"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

android title bar null pointer exception

I know it is simple but I wasnt able to fix it.Tried many solution from SOF.com but none worked. I am trying to display a title for activity and throws NPE. Using API19 for testing.Below are the codes:
In the activity:
public class DisplayImageActivity extends RootActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getActionBar().setTitle("Image Preview");
In the Manifest:
<application
android:allowBackup="true"
android:icon="#drawable/icon"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".DisplayImageActivity"
android:label="< app name >"
android:screenOrientation="portrait" >
</activity>
In the style.xml:
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Finally, the logcat says:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.kittu.<> /com.example.kittu.<>.DisplayImageActivity}: java.lang.NullPointerException

If you are using the support library, your activity needs to extend it
import android.support.v7.app.AppCompatActivity
public class MainActivity extends AppCompatActivity{
and use getSupportActionBar() instead of getActionBar()

I think you are using AppCompat, then you should use getSupportActionBar() instead of getActionBar().
Change this:
getActionBar().setTitle("Image Preview");
to this:
getSupportActionBar().setTitle("Image Preview");
Hope this helps :)

I am a beginner and have been using treehouse to learn. I am very early in the course and suddenly started getting a crash message when I start the app. I am unsure what is happening. I have posted everything that I know of. Sorry if I missed something or posted too much.

import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
private CrystalBall mCrystalBall = new CrystalBall();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Declare our View variables
final TextView answerLabel = (TextView) findViewById(R.id.textView1);
Button getAnswerButton = (Button) findViewById(R.id.button1);
getAnswerButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
String answer = mCrystalBall.getAnAnswer();
// Update label with dynamic answer
answerLabel.setText(answer);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, 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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);

Your Activity extends ActionBarActivity.
public class MainActivity extends ActionBarActivity
Indicates you are using AppCompat in which case you need to set Theme derieved from Theme.AppCompat to the Activity
or
android:theme="#style/Theme.AppCompat" >
set the theme for the application

To simply add ActionBar Compat your activity or application should use #style/Theme.AppCompat theme in AndroidManifest.xml like this:
<activity
...
android:theme="#style/Theme.AppCompat" />
This will add actionbar in activty(or all activities if you added this theme to application)
i.e. in your manifest file,Change
android:theme="#android:style/Theme.Black.NoTitleBar.Fullscreen"
to
android:theme="#style/Theme.AppCompat"

Please change
android:theme="#android:style/Theme.Black.NoTitleBar.Fullscreen"
to
android:theme="#android:style/Theme.AppCompat"

AdView - Missing adActivity with android:configChanges in AndroidManifest.xml

I just set up my app with the Google Play library method of adding adds (AdMob). When I run the emulator the add has the error message:
Missing adActivity with android:configChanges in AndroidManifest.xml
I located a fix at:
Missing adActivity with android:configChanges in AndroidManifest.xml
The fix stated to do the following:
"com.google.ads.AdActivity" is declared when using the admob sdk jar in the "libs" folder. >It seems you're using admob via the google play services library so change:
activity android:name="com.google.ads.AdActivity"
To
activity android:name="com.google.android.gms.ads.AdActivity"
Also make sure you add the meta-data tag:
I tried this and the CatLog said to change the meta tag back to:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />

LinearLayout layout = (LinearLayout) findViewById(R.id.ll);
layout.addView(adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
Here is my Layout:

I also have my Manifest:

You need to leave the meta-data tag as is:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
Additionaly, you need to replace this tag:
<activity
android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
With this (as suggested in the answer you linked):
<activity
android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
Since you are using the Google Play Services and not the legacy AdMob SDK you need to replace the name of the activity class from com.google.ads.AdActivity to com.google.android.gms.ads.AdActivity

This may be part of the problem. It seems you are missing....
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
in you AndroidManifest.xml

Make sure you only have the Google Play Services library included and not both Google Play Services and Admob SDK.
It looks like the value of #integer/google_play_services_version is zero. Are the Google Play Services resources being included in your app?

if you are using unity you should use this.
<!-- Google Mobile Ads Permissions -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Removing the layout declaration and leaving the programmatic one worked. There were also some unrelated issues causing problems with Eclipse.

From update of play service to version 22 you can go without making above change , I am pasting the code for future reference here
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
in androidmanifest.xml file with having google play service as lib. project instead to use admobsdk.jar file

All you have to do is add this to your AndroidManifest.xml file:
<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

it's appear to the screen missing activity with android configchanges in Android manifestxml
