I'm trying to open a web browser from my app using:
Intent browser = new Intent(Intent.ACTION_VIEW, Uri.parse("http://developer.android.com/"));
startActivity(browser);
But the app just crashes:

We tried integrating HelpStack by following steps given on GitHub, but we kept getting the following errors:

I'm guessing it has something to do with the App Theme, which in our case is is Theme.AppCompat.NoActionBar.
I have an autocompletetextview. I want a method to run "onClick". Here is my XML:
<AutoCompleteTextView
android:id="#+id/GivenByBox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="setupMiranda"
android:gravity="left"
/>
When this is run, I get errors. It doesn't matter what onClick is set to, it will always cause an error. If I remove the android:onclick line everything works fine, but that is not what I want.
Here is an excerpt from logCat:

I get this error no matter what function is set onClick. Even a function with an empty body causes this error.
What is causing this error?
Getting run time exception as "inflating class fragment" when I tried to add Google map in my android application. I go through all the previous comments similar to which I have posted. But I couldn't solve it.
Log file is attached here

One visible mistake
https://developers.google.com/maps/documentation/android/start
Your meta tag must be a child of application tag in manifest
<meta-data // should be inside application tag.
android:name="com.google.android.maps.v2.API_KEY"
android:value="********************************" />
Change this
<permission
android:name="com.venky.maps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
to
<permission
android:name="com.example.newapp.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
There seems to be two problems that I am having trouble with. The first case is when I launch the clock app and works perfectly, this seems to be the case when I launch most apps.
The second case is when I try to launch an activity such as the Phone activity. When I go to get the Intent, getLaunchIntentForPackage(app.pname) returns null. Is there a different way to get the Intent of the phone activity so that I can launch it in this case?
The third case is when I go to launch an activity such as the Camera activity. It seems that I have to have the Camera activity already within my androidManifest.xml file to launch it but is there another way to go around this? My app has the capibility to launch any app from its UI so I cannot add every single activity an android device has into my manifest file beforehand. Thank you!
Java:
Intent launchApp = getPackageManager().getLaunchIntentForPackage(app.pname);
System.out.println(Intent of " + appName + ": + " " +launchApp);
if(launchApp!=null){
System.out.println("Permission granted to launch " + appName);
startActivity( launchApp );
}
else{
System.out.println("Permission not granted to launch " + appName);
}

How to launch the camera
How to launch the dialer
to launch a specific app you need to know the package name and the class name
try{
Intent i = new Intent();
i.setClassName("com.example.app", "com.example.app.MainActivity");
i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(e);
}catch(ActivityNotFoundException e){
e.printStackTrace();
}
I am getting the same problem this question, but the solution didn't work for me. I've included my JAR in build path. What wrong am I doing?
I am using the same example.
Here's the crash log:

I recomend you to change libraries to cocos2d-x, because cocos2d for android won't be updated anymore.
Cocos2d-x works in C++, and uses JNI (Java native interface) to work. Here is all the info you will need to start using it.
I guess the problem was in the JAR file. Fortunately the project is open source, so I added the source file and it stopped giving me error. There's a source code available on that tutorial which also uses the source files, instead of the JAR.
I get the same problem. And I copy the source code to src instead of including the jar.
And you must change the project's jre version to 1.6
