I have and android app that allow the user to choose an image from gallery or by capturing by the camera and when I get the single selected/captured photo I put it in my fixed sized imageView with 250dp width and 250dp height.
The problem is it is running in my Emulator but when I installed my app in real device, the posting of photo in imageView doesn't work. How can I fix this?
Thank you in advance
Those 3 "+" are the Image View. This is screen cap from emulator
I select and capture 3 photo and paste it in my Image view, I also want to fit the image in my ImageView
When I run this app in my real device the error comes up after capturing photo. The error is NullPointerException.

I'm creating an image filter app in Android studio. first, the user selects an image from gallery or captures image using camera and it will be displayed in imageview. Then the user clicks edit button and that image is displayed in imageview of next activity where we can add filters... It works fine with low resolution images but when I select any high resolution image or click a high resolution image it is shown in first imageview but when I click edit button either the app crashes or the last image I had selected is displayed. So instead of passing bitmap I thought of passing image uri.I found the solution for image selected from gallery but I want the uri of captured image. I searched for the solution but couldn't find it. If anyone knows how to solve this problem please help me. THANKS

I want to change the size of an image taken by the camera say 600x800. I am successfully doing so and its working fine but I also want to change the byte size or you can say memory as well. Like the photo resizer app https://play.google.com/store/apps/details?id=com.xllusion.app.photoresizer&feature=search_result on google play. For example if I take a photo on this app and change the resolution to 600x800. It creating this resolution photo simply with 23kb(no quality compromise) where as original photo was of 600kb. Can somebody help???
I have implement Gallery and Image Switcher in Eclipse Android Development.
On click of thumbnail, it loads the image and on click of Set Wallpaper, it sets the wallpaper as well. But as soon as the application loads, I want to display the first image from the Gallery to Image Switcher. Other wise if you click on Set Wallpaper, it will throw an exception. After you select an image from the Gallery, it will work fine.
Can anyone please help me how to show the first image of the gallery in Image Switcher so that when I click Set Wallpaper without selecting an image, it should work fine
One more thing, after image switcher initialization, I have set the first image but it takes the entire window in Emulator? If you select an image it show the preview.
Thanks in advance.
