Capturing a picture and than displaying within an ImageView - Android
Hey guys I am using my webcam to simulate a camera in the emulator and when I go to take the picture and select the check mark button to use the picture I run across an error while trying to display the image back into my ImageView on the app.
Here is my code:
Initiator:
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
function....
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
Bitmap bm = BitmapFactory.decodeFile(imagePath);
Log.w("Here","error");
Bitmap bm = BitmapFactory.decodeFile(imagePath);
ImageView image = (ImageView) findViewById(R.id.gimg1);
image.setImageBitmap(bm);
} else if (resultCode == RESULT_CANCELED){
}
}
}
I run across a runtime error
Suggestions and thoughts are needed!

Very Simple way to Click button and set store image in imageview.
`public class MainActivity extends Activity {
private static final int CAMERA_PIC_REQUEST = 22;
Uri cameraUri;
Button BtnSelectImage;
private ImageView ImgPhoto;
private String Camerapath ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImgPhoto = (ImageView) findViewById(R.id.imageView1);
BtnSelectImage = (Button) findViewById(R.id.button1);
BtnSelectImage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// TODO Auto-generated method stub
try {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
});
}
@Override
public void onActivityResult(final int requestCode, int resultCode, Intent data) {
try {
switch (requestCode) {
case CAMERA_PIC_REQUEST:
if (resultCode == RESULT_OK) {
try {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ImgPhoto.setImageBitmap(photo);
} catch (Exception e) {
Toast.makeText(this, "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
break;
default:
break;
}
} catch (Exception e) {
}
}
}`
Set this Manifest.
<uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature>

You can use the following codes. It's fully functional and allows you set image from both your camera and gallery as well. I am almost sure that your runtime error is "OutOfMemoryError: bitmap size exceeds VM budget" as I am seeing that you have loaded the captured image directly to your imageView. You should scale it , please take a look at the method called GetScaledBitmap in my following code. Hope your codes will work ok if you use that method only when you load the image to your imageview. Full example is done for you , Hope it helps.

if(requestCode==CAMERA_PIC_REQUEST && resultCode==RESULT_OK){
Bitmap image = (Bitmap) data.getExtra("data");
image_taken.setImageBitmap(image);
}
You were calling data.getData() whereas it should have been data.getExtra("data") as data is an intent which you will have put the bitmap
