Taking pictures with camera on Android programmatically

Look at following demo code.

Here is your XML file for UI,

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <Button        android:id="@+id/btnCapture"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="Camera" /></LinearLayout>

And here is your Java class file,

public class CameraDemoActivity extends Activity {    int TAKE_PHOTO_CODE = 0;    public static int count = 0;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        // Here, we are making a folder named picFolder to store        // pics taken by the camera using this application.        final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";        File newdir = new File(dir);        newdir.mkdirs();        Button capture = (Button) findViewById(R.id.btnCapture);        capture.setOnClickListener(new View.OnClickListener() {            public void onClick(View v) {                // Here, the counter will be incremented each time, and the                // picture taken by camera will be stored as 1.jpg,2.jpg                // and likewise.                count++;                String file = dir+count+".jpg";                File newfile = new File(file);                try {                    newfile.createNewFile();                }                catch (IOException e)                {                }                Uri outputFileUri = Uri.fromFile(newfile);                Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);                startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);            }        });    }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {            Log.d("CameraDemo", "Pic saved");        }    }}

Note:

Specify the following permissions in your manifest file,

<uses-permission android:name="android.permission.CAMERA"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

There are two ways to take a photo:

1 - Using an Intent to make a photo

2 - Using the camera API

I think you should use the second way and there is a sample code here for two of them.

You can use Magical Take Photo library.

1. try with compile in gradle

compile 'com.frosquivel:magicaltakephoto:1.0'

2. You need this permission in your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.CAMERA"/>

3. instance the class like this

// "this" is the current activity param

MagicalTakePhoto magicalTakePhoto =  new MagicalTakePhoto(this,ANY_INTEGER_0_TO_4000_FOR_QUALITY);

4. if you need to take picture use the method

magicalTakePhoto.takePhoto("my_photo_name");

5. if you need to select picture in device, try with the method:

magicalTakePhoto.selectedPicture("my_header_name");

6. You need to override the method onActivityResult of the activity or fragment like this:

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {     super.onActivityResult(requestCode, resultCode, data);     magicalTakePhoto.resultPhoto(requestCode, resultCode, data);     // example to get photo     // imageView.setImageBitmap(magicalTakePhoto.getMyPhoto());}

Note: Only with this Library you can take and select picture in the device, this use a min API 15.
