Cannot run Android "Camera Preview" sample

Cannot run Android "Camera Preview" sample - android

The sample I'm referring to is: CameraPreview.
The program simply force closes upon start up. I've also tried other camera demos that have the same problem.
I'm trying to run the samples on my Nexus One and the emulator with the same problem on both. I'm not even sure if the emulator should be able to run them or not.
Based on LogCat, the error is:

All I did to try out the sample was create a new Android 2.1update1 Project, named everything according to the supplied Java file, copied the Java file from the URL to the CameraPreview.java file, then run it. Am I supposed to do anything else?
Any help would be appreciated. Thanks in advance.

Add the following to your manifest, as children of the <manifest> element:
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.CAMERA" />

I solved this error by placing gms library separately:
Before I have used :
compile 'com.google.android.gms:play-services:8.1.0'
That above one line will take care of GCM and all google related libaries.But this one line cause a verifier error.On top of the verifier error you can see some gms related log.
After that I have added separately like this to fix this issue :
compile 'com.google.android.gms:play-services-location:8.1.0'
compile 'com.google.android.gms:play-services-base:8.1.0'
compile 'com.google.android.gms:play-services-analytics:8.1.0'
compile 'com.google.android.gms:play-services-maps:8.1.0'
compile "com.google.android.gms:play-services-gcm:8.1.0' // for gcm push notification

How to solve "Out of memory" during image processing on Imagine SDK android [duplicate]

This question already has answers here:
Strange OutOfMemory issue while loading an image to a Bitmap object
(44 answers)
Closed 7 years ago.
as i am implementing both OCR and Imagine SDK for our app, i need your help to solve this problem.
i have a method like below.
public void ImageProcessing(View v) {
try {
MIContext _miContext = MIContext.getInstance();
_miContext.clearAll();
Uri _imageUri = Uri.fromFile(GetImageFile("form.jpg")); // GetImageFile() will return a file
ImageOperation _imageOperation = ImageOperation.AUTO_ENHANCE;
OperationController _operationController = _imageOperation.getController();
_miContext.loadSourceImage( _imageUri, this );
final FineOperation fineOperation = _operationController.createOperation();
_miContext.run( fineOperation );
} catch (Exception e) {
Log.v("mango", e.getMessage());
}
}
when i execute it. it returns "Out of memory: Heap Size=7943KB, Allocated=4113KB, Bitmap Size=24888KB, Limit=32768KB"
below is my logcat output.

am i doing something wrong ? Hemp help me guys

You can try increasing the allocated memory to your application. In android Every application gets a chunk of memory allocated. but in case of image processing application it is most likely to fall short of that memory.
Also try manually cleaning up the memory in your app. The android garbage collector usually have bitmap image memory leakages.
you can get a good read up on this via following link
bitmap memory managment

Use this in your application tag of Manifest file ..
android:largeHeap="true"

I'm getting the same error on an application I've developed for Android 2.1 and Android 2.2 but run on Android 4.0.1 ICS. The same app would run on Android 2.1 but cause a crash with the above error on ICS. If you're drawing something relatively big to the size of the screen, consider checking from that place.

NullPointerException app loading

When my app loads the following error comes up on some devices. It refers to none of my source files at all! How do I go about fixing this one?

As mentioned here: Marking Current Location on Map, Android and here http://code.google.com/p/android/issues/detail?id=2035, you may need to call overlays.populate(); method in your code.
