Permissions

<!-- 往SDCard写入数据权限 --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <!--请求访问使用照相设备--><uses-permission android:name="android.permission.CAMERA" />

Constant

 public final static int album_request_code = 1; 
 public final static int crop_request = 2; 
 public final static int camera_request_code = 3; 
 Photo Path 
 public static String Saved_image_dir_path = Environment.getexternalstoragedirectory (). GetPath () +  "/appname/camera/";

Camera

Specify camera to take photo save address
String state = Environment.getexternalstoragestate ();
if (State.equals (environment.media_mounted)) {Camerapath = Saved_image_dir_path + system.currenttimemillis () +". png"; Intent Intent =New Intent ();
 Specifies the ACTION intent.setaction (mediastore.action_image_capture) to turn on the system camera;    String Out_file_path = Saved_image_dir_path;    File dir = new file (Out_file_path);    if (!dir.exists ()) {dir.mkdirs (); } //Convert the file address to URI format URI uri = uri.fromfile (new File (Camerapath));
//Set the system camera to take photos after the picture file storage address Intent.putextra (Mediastore.extra_output, URI); Startactivityforresult (Intent, camera_request_code);} else {toast.maketext (Getapplicationcontext (), "Please confirm that the SD card is plugged in", Toast.length_long). Show ();  

Onactivityresult

Get Camerapath, just do whatever you want.

@Override

public void onActivityResult(int requestCode, 
int resultCode, Intent data) {    
super.onActivityResult(requestCode, resultCode, data);    
if (resultCode == Activity.RESULT_OK) {        
if (requestCode == CAMERA_REQUEST_CODE) {            LogUtil.d("path=" + cameraPath);        } }

Album

new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, ALBUM_REQUEST_CODE);

Onactivityresult

Call the system album and get the absolute address of the picture via the URI.

 @OverridePublicvoidOnactivityresult(int Requestcode,
int ResultCode, Intent data) {
 Super.onactivityresult (Requestcode, ResultCode, data);
 if (ResultCode = ACTIVITY.RESULT_OK) {          
 if (Requestcode = = Appconstants.album_request_code) {              < br> try {

     &NB Sp    } catch (Exception e) {                &N Bsp  e.printstacktrace ();           
          }            } &nb Sp      }    }      

GetAbsolutePath method

 Public StringGetAbsolutePath(Final context Context,
Final URI Uri) {
if (Null = = URI)ReturnNull
Final String scheme = Uri.getscheme (); String data =Null
