The strongest android in history to open a photo or to select a picture from a local album after the first crop in the save and display the source of the explanation attached

The layout of the whole program is simple

A linear layout in a vertical direction with two buttons (button) and a control to display the picture (ImageView)
This part of the code is not given here.

1. Is the album that opens the system

Intent (Intent.  Action_picknull); Albumintent.setdataandtype (MediaStore.Images.Media.  External_content_uri"image/*"album_ok);

Here is a local album opened by the implicit intent of starting a system

2. It's the camera that opens the system.

Intent (Mediastore.  Action_image_capture); ///The following sentence specifies the path of the photo storage after the camera is called  (pre. Exists ()) {    pre. Delete ();}  {    pre(IOException e) {    e.printstacktrace ();} Cameraintent.putextra (Mediastore.  Extra_output, Uri.fromfile (precamera_ok);

Open the camera by opening an implicit intent

3. Cropping the clipping here is also through an implicit intent to invoke the function of the system

/** * Crop image method implementation  *   Image source */Clipphoto (Uri uri) {Intent (       "Com.android.camera.action.CROP");    "image/*");    Intent.putextra ("crop""true");    //Aspectx aspecty is the ratio of width to height, where the square is set (aspect ratio is 1:1)Intent.putextra ("Aspectx", 1);    Intent.putextra ("Aspecty", 1);    //Outputx outputy is a cropped image with a wide height of Intent.putextra ("OUTPUTX");    Intent.putextra ("outputy");    Intent.putextra ("Return-data"true);    cut_ok);}

4. Display and save pictures

/** * Save the picture data after cropping to set the picture to ImageView  *  picdata */Setpictoview (Intent picdata) {clog.d     (TAG  "Display the picture on the control");    Bundle extras = Picdata.getextras ();     null) {        = extras.getparcelable ("Data");         TODO Set the picture before you should delete the previous picture, save the latest picture Readbitmap2file (bitmap);        Headphoto. Setimagebitmap (bitmap);    }}

The following is the source code for the entire program (which also includes a team image for two samples of the tool class)

There is a problem to be verified.

When I saved the picture, it was my practice to determine if the SDcard card was available,

Unavailable cases are saved directly to the phone memory, in this place, someone and I mentioned that it seems that due to certain problems, it cannot be saved to this place.

If available, save directly on the SDcard card.
