Encoding and saving image to sd card

Encoding and saving image to sd card - android

I have a problem where I have to take an Image from the gallery and save it to the memory card after compressing it. I am able to pick the image from the gallery and even save it. But somehow there seems to be some coding mistake due to which I can not open the Image. Here is the code:
public class MainActivity extends Activity {
ImageView image;
Button save, add;
String fileName;
final Context context = this;
Bitmap bitmap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
save = (Button)findViewById(R.id.buttonSave);
add = (Button)findViewById(R.id.buttonAdd);
image = (ImageView)findViewById(R.id.imageView);
add.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 0);
}
});
save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
LayoutInflater li = LayoutInflater.from(context);
View promptsView = li.inflate(R.layout.rename_dialog, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompts.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editRename);
alertDialogBuilder
.setTitle("Save Image")
.setMessage("Enter name")
.setNegativeButton("Save", new DialogInterface.OnClickListener() {
//
#Override
public void onClick(DialogInterface dialog, int which) {
fileName = userInput.getText().toString();
Log.d("Name" , fileName);
saveFile(null, fileName);
Toast.makeText(getApplicationContext(), "Image saved", Toast.LENGTH_SHORT).show();
}
})
.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
Toast.makeText(getApplicationContext(), "Image save cancelled", Toast.LENGTH_SHORT).show();
}
});
AlertDialog build = alertDialogBuilder.create();
build.show();
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK){
Uri targetUri = data.getData();
try {
bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(targetUri));
image.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private void saveFile(Bitmap images, String fileName) {
BitmapDrawable drawable = (BitmapDrawable) image.getDrawable();
bitmap = drawable.getBitmap();
File sdCard = Environment.getExternalStorageDirectory();
File pic = new File(sdCard , fileName + ".jpeg");
boolean success = false;
FileOutputStream outStream;
try {
outStream = new FileOutputStream(pic);
//bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
/* 100 to keep full quality of the image */
outStream.flush();
outStream.close();
success = true;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Image saved with success",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during image saving", Toast.LENGTH_LONG).show();
}
}
}

Upload image to server from gallary or camera android

i have a Activity for Upload image from gallary or camera to server.image upload from camera is fine but upload from gallary is not done.i have a error showing
BitmapFactory﹕ Unable to decode stream: FileNotFoundException
i want to do when i pick up the image from gallary it is shown in other Activity on image view.
i don't know how to get fileuri for gallary please help me.
my code:
loadimage = (ImageView) findViewById(R.id.profilpic);
loadimage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
/* Intent i = new Intent(Tab1.this, ImageMain.class);
startActivity(i);*/
// selectImageFromGallery();
AlertDialog.Builder builder = new AlertDialog.Builder(Tab1.this);
builder.setMessage("Select Image From")
.setCancelable(true)
.setPositiveButton("camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_REQUEST);
}
})
.setNegativeButton("gallary", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}
});
AlertDialog alert = builder.create();
alert.show();
}
});
Hear is my onActiivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_REQUEST) {
if (resultCode == RESULT_OK) {
launchUploadActivity(true);
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),
"User cancelled image capture", Toast.LENGTH_SHORT)
.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)
.show();
}
}
else if(requestCode==RESULT_LOAD_IMAGE){
if (resultCode==RESULT_OK){
launchUploadActivity(true);
}
}
}
private void launchUploadActivity(boolean isImage){
Intent i = new Intent(Tab1.this,UploadAvtivity.class);
i.putExtra("filePath", fileUri.getPath());
i.putExtra("isImage", isImage);
startActivity(i);
}

Here is the Code piece for Taking a Picture through Default Camera (here I implemented Intent to to fetch the image). After that store it to SD card(here a new file will be created and the newly taken image will be stored ); and if you don't want to store then remove the saving part from code. After that you can use the file path for your upload purpose. You can then refer it and change to get the path as your wish.
In the class area put these lines
final int TAKE_PHOTO_REQ = 100;
String file_path = Environment.getExternalStorageDirectory()
+ "/recent.jpg";//Here recent.jpg is your image name which will going to take
After that invoke the camera by putting these line in calling method.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, TAKE_PHOTO_REQ);
then add this method in your Activity to get the picture and save it to sd card and you can invoke your upload method from here to upload the image by knowing its path.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PHOTO_REQ: {
if (resultCode == TakePicture.RESULT_OK && data != null) {
Bitmap srcBmp = (Bitmap) data.getExtras().get("data");
// ... (process image if necesary)
imageView.setImageBitmap(srcBmp);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
srcBmp.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
// you can create a new file name "test.jpg" in sdcard folder.
File f = new File(file_path);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// write the bytes in file
FileOutputStream fo = null;
try {
fo = new FileOutputStream(f);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// remember close de FileOutput
try {
fo.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.e("take-img", "Image Saved to sd card...");
// Toast.makeText(getApplicationContext(),
// "Image Saved to sd card...", Toast.LENGTH_SHORT).show();
break;
}
}
}
}
Hope this will be helpful for you and others too .. thanks

Save captured image

I have been trying to work this out but not having any success.
I have a really simple app that captures an image and displays that image to the user. The problem is that it saves the image as the date is was captured, but instead I want to give the image a specific name.
Here is my code:
#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) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, CAMERA_REQUEST);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
System.gc();
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
I would really appreciate it if someone could show me what I need to add and where to set the image name.

Try 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();
}
}
}

Android Complete Action Using

Hi I have this button and when I click on it I'd like to launch a Complete Action Using window that would allow me to choose between Camera & Gallery.
Is there an easier way to implement this other than creating a dialog.

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(
context.getString(R.string.Select_an_Option_to_add_Photo))
.setCancelable(true)
.setPositiveButton(context.getString(R.string.Camera),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
try {
Intent action = new Intent(
"android.media.action.IMAGE_CAPTURE");
action.putExtra(
MediaStore.EXTRA_OUTPUT,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI
.toString());
startActivityForResult(action, 8);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
})
.setNegativeButton(context.getString(R.string.Gallery),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
try {
Intent photoPickerIntent = new Intent(
Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
alert = builder.create();
Now
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && requestCode == 8) {
Bitmap photoBitMap = (Bitmap) data.getExtras().get("data");
Bitmap usableBMP = Bitmap.createScaledBitmap(photoBitMap, 68, 80,
true);
//This is my ImageView Object
cameraButton.setImageBitmap(usableBMP);
cameraButton.setScaleType(ScaleType.CENTER_INSIDE);
} else if (resultCode == RESULT_OK) {
Uri chosenImageUri = data.getData();
try {
//Here I scale my Bitmap as desired
photoBitMap = Media.getBitmap(this.getContentResolver(),
chosenImageUri);
Bitmap usableBMP = Bitmap.createScaledBitmap(photoBitMap, 68,
80, true);
//this is my ImageView Object
cameraButton.setImageBitmap(usableBMP);
cameraButton.setScaleType(ScaleType.CENTER_INSIDE);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
