Guys,I am trying to integrate admob SDK in my app from the past 3 hours and have no luck.
I have added the jar libraries ( build path), included in build paths, everything is good there.
main activity :
Code:
// Create the adView
adView = new AdView(this, AdSize.BANNER, MY_AD_UNIT_ID);
// Lookup your LinearLayout assuming it's been given
// the attribute android:id="@+id/mainLayout"
RelativeLayout layout = (RelativeLayout)findViewById(R.id.ad);
// Add the adView to it
layout.addView(adView);
// Initiate a generic request to load it with an ad
adView.loadAd(new AdRequest());
layout
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:id="@+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<com.google.ads.AdView
android:id="@+id/ad"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
ads:adSize="BANNER"
ads:adUnitId="a15XZXXXXX3"
ads:loadAdOnCreate="true" />
everything loaded on the manifest file as well!

says there, line 42, your asking "NULL" to do something! No idea what is on line 42, but would assume it's your ad view, so maybe your loading the wrong layout ? or even attempting to findViewById before setContentView() ? Would need more info/code

Hi,
You are mixing the two solutions for integration of admob banners (XML and code). The coding solution assumes that you have a layout that you want to populate with ads (useful when using different ad networks). In your case you define the admob banner in the XML so you don't need to call it at all in the code, If you think to set a listener (to do something when admob failed to show ads) in this case you can call and set your ad listener (that you implement on the activity) this way:
AdView adView = (AdView)findViewById(R.id.ad);
adView.setAdListener (this);
adView.loadAd(new AdRequest());
Hope this will help

Please help me out! Thanks in advance..
Aren't there prefixes for the Uris?
Try "tel:<your number>" for example for the dial intent. (If that does not work, search for the right prefix.)
Its strange, i got this code from a book (begining android application development.)
How can it be faulty..
I dont find any prefix for the uriS
edit:
Actually, there is a prefix for the dialing intent.
But not, for the browser intent.
So, my app is still cashing
edit: actually, it.worked. But the map is still crashing

The following are the contents within the LineaLlayout in my main.xml file:
Code:
<TextView

android:text="@string/result"
android:textSize="25sp"
android:layout_gravity="fill_horizontal"
android:gravity="center"
android:id="@+id/display"

<Button
android:layout_width="250dp"
android:layout_height="wrap_content"
android:text="@string/bAdd"
android:layout_gravity="center"
android:gravity="center"
android:id="@+id/bAdd"

<Button

android:layout_height="wrap_content"
android:text="@string/bSub"
android:layout_gravity="center"
android:gravity="center"

And this is what the logcat has to say :

Being inexperienced in java , I could not figure out what's wrong with the code.May be the exception is due to my add,sub and display being null but I am not sure.Please help me figure out what's wrong with my code and how to deal with it.
Any help is greatly appreciated.
Well, you can find the line where it crashes in the logcat:
Code:

It's line 21. Which one is that?
Have a look at my debugging tutorial here as well, mainly the part on understanding the logcat. It will probably be very helpful and save much time: http://forum.xda-developers.com/showthread.php?t=2325164

It means the.view with id bAdd was not found make sure have declared it in your layout

I have declared the ids for each view as you can see in the layout.xml attached.This NPE is turning out to be quite frustrating now.

do one thing
add a breakpoint to each line
then debug your app if on Eclipse or Android Studio !
and watch the control flow through each line this should narrow you down to the root cause.

WebView wv = (WebView) findViewById(R.id.main_content);

XML:
Code:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="LINK WAS HERE"
android:id="@+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"

<WebView
android:id="@+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
Check the xml.main_content id that you used to identify webview is for framelayout.
You have to replace main_content with webView in your java code.
Moreover your first framelayout never ends

i did. Same error!:crying:
Try writing the full package name to instead of just "MainActivity"
<activity android:name="app2.android.MainActivity" >
In the manifest change your activity name to <activity android:name="app2.android.MainActivity" > and also make sure that your project src folder has correct package inside (named app2.android)
Hey guys,
I'm having a problem figuring out a way to store the geofences that my app creates, in order to load them when I run the app again. The purpose is to show a list of geofences created by the user.
I tried to serialize them using Java's Serialization and I also tried to use Gson to convert them into a Json string. The problem with Gson it's when I try to load them, it gives me an error message saying that Geofence is not a class. (which is true, it's an interface).

Hey guys,
I'm having a problem figuring out a way to store the geofences that my app creates, in order to load them when I run the app again. The purpose is to show a list of geofences created by the user.
I tried to serialize them using Java's Serialization and I also tried to use Gson to convert them into a Json string. The problem with Gson it's when I try to load them, it gives me an error message saying that Geofence is not a class. (which is true, it's an interface).
Thank you in advance.
