Question

我有一个活动，我给用户一个选项来点击相机中的图像，然后我将这个图像存储在一个字节数组和数据库中。但是我的代码似乎不适用于三星Galaxy S3下面是代码：

相机调用意图：

if (i == 0) {
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); 
}

开启相机的活动方法：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == 1337 && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        if (extras != null) {   
            BitmapFactory.Options options = new BitmapFactory.Options();
            thumbnail = (Bitmap) extras.get("data");
            image(thumbnail);
        } else {
            Toast.makeText(CreateProfile.this, "Picture NOt taken", Toast.LENGTH_LONG).show();
        }

        super.onActivityResult(requestCode, resultCode, data);     
    }
}

我的图片（位图缩略图）功能：

public void image(Bitmap thumbnail) {
    Bitmap photo = thumbnail; 
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
    b = bos.toByteArray();
    ImageView imageview = (ImageView)findViewById(R.id.imageView1);
    Bitmap bt = Bitmap.createScaledBitmap(photo, 100, 80, false);  
    imageview.setImageBitmap(bt);
}

然而，这不适用于三星S3，我将代码更改为以下内容，现在它适用于三星S3，但它不适用于任何其他设备。

相机意图：

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

结果活动：

startActivityForResult(intent, CAMERA_IMAGE_CAPTURE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
        // Describe the columns you'd like to have returned. Selecting from the Thumbnails location gives you both the Thumbnail Image ID, as well as the original image ID
String[] projection = {
 MediaStore.Images.Thumbnails._ID,  // The columns we want
 MediaStore.Images.Thumbnails.IMAGE_ID,
 MediaStore.Images.Thumbnails.KIND,
 MediaStore.Images.Thumbnails.DATA};
 String selection = MediaStore.Images.Thumbnails.KIND + "="  + // Select only mini's
 MediaStore.Images.Thumbnails.MINI_KIND;

 String sort = MediaStore.Images.Thumbnails._ID + " DESC";

//At the moment, this is a bit of a hack, as I'm returning ALL images, and just taking the latest one. There is a better way to narrow this down I think with a WHERE clause which is currently the selection variable
Cursor myCursor = this.managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, selection, null, sort);

long imageId = 0l;
long thumbnailImageId = 0l;
String thumbnailPath = "";

try{
 myCursor.moveToFirst();
imageId = myCursor.getLong(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
thumbnailImageId = myCursor.getLong(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
thumbnailPath = myCursor.getString(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
}
finally{myCursor.close();}

 //Create new Cursor to obtain the file Path for the large image

 String[] largeFileProjection = {
 MediaStore.Images.ImageColumns._ID,
 MediaStore.Images.ImageColumns.DATA
 };

 String largeFileSort = MediaStore.Images.ImageColumns._ID + " DESC";
 myCursor = this.managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, largeFileProjection, null, null, largeFileSort);
 String largeImagePath = "";

try{
 myCursor.moveToFirst();

//This will actually give yo uthe file path location of the image.
largeImagePath = myCursor.getString(myCursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
}
finally{myCursor.close();}
 // These are the two URI's you'll be interested in. They give you a handle to the actual images
 Uri uriLargeImage = Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, String.valueOf(imageId));
 Uri uriThumbnailImage = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, String.valueOf(thumbnailImageId));

// I've left out the remaining code, as all I do is assign the URI's to my own objects anyways...
// Toast.makeText(this, ""+largeImagePath, Toast.LENGTH_LONG).show();
// Toast.makeText(this, ""+uriLargeImage, Toast.LENGTH_LONG).show();
// Toast.makeText(this, ""+uriThumbnailImage, Toast.LENGTH_LONG).show();

    if (largeImagePath != null) {
        // Toast.makeText(this, "" + largeImagePath, Toast.LENGTH_LONG).show();

        BitmapFactory.Options opts = new BitmapFactory.Options();
        opts.inSampleSize = OG;
        // thumbnail = (BitmapFactory.decodeFile(picturePath));
        thumbnail = BitmapFactory.decodeFile((largeImagePath), opts);
        System.gc();
        if (thumbnail != null) {
            Toast.makeText(this, "Success", Toast.LENGTH_LONG).show();
        }

        image(thumbnail);

    }

    if (uriLargeImage != null) {
        Toast.makeText(this, "" + uriLargeImage, Toast.LENGTH_LONG).show();
    } 

    if (uriThumbnailImage != null) {
        Toast.makeText(this, "" + uriThumbnailImage, Toast.LENGTH_LONG).show();
    }
}

这是我的image（）函数：

public void image(Bitmap thumbnail) {
    b = null;

    Bitmap photo = thumbnail; 
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
    b = bos.toByteArray();

    if (b != null) {
        Toast.makeText(this, "Success Yeah" + b, Toast.LENGTH_LONG).show();
    }
}

虽然全部三个1）uriLargeImage 2）largeImagePath 3）uriThumbnailImage返回路径或URI我无法将创建的位图设置为我的ImageView。然而，只有三星S3的情况，如果我用任何其他设备运行上面编辑的代码，程序崩溃。

在我使用的清单中

android:configChanges="keyboardHidden|orientation"

基于教程：http://kevinpotgieter.wordpress.com/2011/03/30/null-intent-passed-back-on-samsung-galaxy-tab/

但是，如果我以风景模式拍摄照片，一切正常！我很困惑!! （在三星S3中）

Answer 1

最后经过三天的努力，我设计了一个简单的机制来克服三星S3 Saga。

下面是代码，代码的快速摘要是我首先检查设备的制造商，并根据此我调用相机的不同意图。

public class MainActivity extends Activity {

    private static int RESULT_LOAD_IMAGE = 1;
    private static final int PICK_FROM_GALLERY = 2;
    int CAMERA_PIC_REQUEST = 1337;
    Bitmap thumbnail = null;
    private static final int OG = 4;

    private static final int CAMERA_IMAGE_CAPTURE = 0;
    Uri u;
    ImageView imgview;
    // int z=0;
    String z = null;
    byte b[];
    String largeImagePath = "";
    Uri uriLargeImage;
    Uri uriThumbnailImage;
    Cursor myCursor;

    public void imageCam(Bitmap thumbnail) {
        Bitmap photo = thumbnail;
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        photo.compress(Bitmap.CompressFormat.JPEG, 70, bos);
        b = bos.toByteArray();
        ImageView imageview = (ImageView) findViewById(R.id.imageView1);
        imageview.setImageBitmap(photo);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button bt = (Button) findViewById(R.id.button1);
        bt.setOnClickListener(onBTN);
        if (savedInstanceState != null) {

            Bitmap Zatang;
            String B1 = savedInstanceState.getString("message");
            Toast.makeText(this, "SavedYeah" + B1, Toast.LENGTH_LONG).show();
            BitmapFactory.Options opts = new BitmapFactory.Options();
            opts.inSampleSize = OG;
            Zatang = BitmapFactory.decodeFile((B1), opts);
            System.gc();
            if (Zatang != null) {
                Toast.makeText(this, "Success Zatang" + B1, Toast.LENGTH_LONG)
