Hello Guys,
I am here after long time and today i am posting one new sample.
Today I have build simple example in which you can select either Camera or Gallery to pick up an image.For that you have to simple click on Default image and that will launch dialog to ask selection alternative Camera / Gallery.
You can choose any one of them and pick up single image form respective item index either it could be Camera or Gallery.
I will upload next sample in which you can select multiple images from Gallery and use that path.
One Major thing that i have use here and that is
Copy Image to your own created Folder. It means when you Capture any image from Camera or Gallery that image will be copied and pasted into your specific /DIR and we will use that image path from target /dir.
So, You can save and safe your images in your own directory.
Now What you will learn from this post ?
- How to Capture image from camera in android ?
- How to Pick up image from Gallery in android ?
- How to launch alert dialog for image selection either Camera & Gallery ?
- How to create folder in SD Card ?
- How to copy image at specific folder in SD Card ?
- How to create Random File name for image ?
- How to set Header & Footer fix view using Linear Layout in android ?
Let start with XML layout. (I will show only major code here)
Main.xml

Image Selection Mode Camera or Gallery Dialog
- After the selection of one of the mode you will get either Camera screen or Gallery screen , Here you have to select any single image.
- If you are not selecting any image then result should be blank.

After Selection of Image
- Yeah, Now you have select any single image and that will come with
onActivityResult.
- Now do some copy & decoding task

super.onActivityResult(requestCode, resultCode, data);
if (requestCode == Utility.GALLERY_PICTURE) {
Image_Selecting_Task(data);
} else if (requestCode == Utility.CAMERA_PICTURE) {
Image_Selecting_Task(data);
}
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == Utility.GALLERY_PICTURE) {
// data contains result
// Do some task
Image_Selecting_Task(data);
