ry the below code is one of the solution to your problem::
static Uri capturedImageUri = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.imageView = (ImageView) this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
photoButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Calendar cal = Calendar.getInstance();
File file = new File(Environment.getExternalStorageDirectory(), (cal.getTimeInMillis() + ".jpg"));
if (!file.exists()) {
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
file.delete();
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
capturedImageUri = Uri.fromFile(file);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, capturedImageUri);
startActivityForResult(i, CAMERA_RESULT);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
//Bitmap photo = (Bitmap) data.getExtras().get("data");
//imageView.setImageBitmap(photo);
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), capturedImageUri);
imageView.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Solution 2
your error clearly says that java.io.FileNotFoundException: /filename
please provide exact path "/sdcard/filename"
new FileOutputStream(getExternalStorageDirectory()+"filename");
OR
String imageFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/name.png";
note: add permission WRITE_EXTERNAL_STORAGE in manifest file.
