Please help me out with this Android camera.
The error I get is below:
Unable to resume activity {..,CreatePropertyActivity5}: Failure delivering result ResultInfo{who=null, request=100, result=-1, data=null} to activity..: java.lang.NullPointer
It also gives this warning which is strange since I compress the images:
W/OpenGLRenderer(10242): Bitmap too large to be uploaded into a texture (3264x2448, max=2048x2048)
My app allows the user to select a photo from gallery or take one using camera.
As u can figure out from the code there is no limit to the number of photos the user adds.
In the main page (createPropertyActivity*5*) the user touches the Take photo Button, she chooses the camera or gallery, then she selects (or takes) a picture, then the app goes to a page (CreatePropertyActivity*51* ) in which she can either cancel or write a description for the image.
When she touches "send photo button" she goes back to main page, the photo is sent to the server, and an image view is added to the bottom of the previously added images in the main page so the user can see all the images she has selected.
SOMETIMES (and I don't know when that happens, sometimes it's when the 4th picture is added, sometimes when the first!) It gives the error! (esp when the camera is on high resolution).
I compress the photos and everything. What am I doing wrong?
Does it have anything to do with the file name? Compression?
What is wrong in my code? I have no clue!
Here my code :
public class CreatePropertyActivity5 extends ActionBarActivity {
protected static final int SELECT_PICTURE = 1;
private static final int ACTIVITY_REQUEST_CODE_IMAGE = 100;
private static final int IMAGE_DESCRIPTION = 200;

Answer
That's what I expected. Android is killing your process while the Camera or Gallery is running because it needs the resources. When the user returns to your app, Android has started a new process and is recreating your activities. What you'll need to do is override onSaveInstanceState() and onRestoreInstanceState() and save and restore anything that needs to be preserved while the user is playing with the camera or gallery app.
