Android calls the System camera three steps, Android calls three steps

Step 1:

<Uses-permissionandroid: name = "android. permission. WRITE_EXTERNAL_STORAGE"/>

<Uses-permissionandroid: name = "android. permission. MOUNT_UNMOUNT_FILESYSTEMS"/>

Step 2:

Intent intent = new Intent (MediaStore. ACTION_IMAGE_CAPTURE );

 

StartActivityForResult (intent, 1 );

Step 3:

Protected void onActivityResult (int requestCode, int resultCode, Intent data ){
// TODO Auto-generated method stub
Super. onActivityResult (requestCode, resultCode, data );
If (resultCode = NewsActivity. RESULT_ OK ){
String sdStatus = Environment. getExternalStorageState ();
If (! SdStatus. equals (Environment. MEDIA_MOUNTED) {// check whether sd is available
Log. I ("TestFile ",
"SD card is not avaiable/writeable right now .");
Return;
}
String name = new DateFormat (). format ("yyyyMMdd_hhmmss", Calendar. getInstance (Locale. CHINA) + ". jpg ";
Toast. makeText (this, name, Toast. LENGTH_LONG). show ();
Bundle bundle = data. getExtras ();
Bitmap bitmap = (Bitmap) bundle. get ("data"); // obtain the data returned by the camera and convert it to the Bitmap image format.

FileOutputStream B = null;
//??????????????????????????????? Why can't I save it directly in the system album ????????????
File file = new File ("/sdcard/myImage /");
File. mkdirs (); // create a folder
String fileName = "/sdcard/myImage/" + name;

Try {
B = new FileOutputStream (fileName );
Bitmap. compress (Bitmap. CompressFormat. JPEG, 100, B); // write data to a file
} Catch (FileNotFoundException e ){
E. printStackTrace ();
} Finally {
Try {
B. flush ();
B. close ();
} Catch (IOException e ){
E. printStackTrace ();
}
}
ImageView iv = (ImageView) findViewById (R. id. news_ImageView_image );
Iv. setImageBitmap (bitmap );
}
