Question

我的应用程序的基本结构是：

在我的应用的第一个屏幕上，用户点击了一个按钮，TAKE PICTURE。
手机的默认相机应用程序出现，用户即可拍照。
必须显示照片，并要求用户输入他的姓名和电话号码。
必须将姓名，电话号码和图像附加到要发送到预定义地址的电子邮件中。（gmail android app）

我的问题是当我在拥有android 2.3的三星手机上运行我的应用程序时，它完美运行（我得到了我最近点击过的图像），但是当我在拍摄照片后尝试使用Android 4.2的sony手机时，它显示的是另一张照片而不是我最近拍摄的照片。

我的代码在这里我的第一页代码：它接受图像并调用另一个活动INF.java

Cameraproject.java

public class CameraProject extends Activity {

Button button;
Bitmap btm;
Bitmap thumbnail;
String filePath;
  File pic;
final static int CameraData = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_camera_project);
    button = (Button) findViewById(R.id.cont);


}


//start camera activity
public void camera(View v) {
    Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(i, CameraData);
            }

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        btm = (Bitmap) extras.get("data");

    }
        if(resultCode == RESULT_OK)
        {
            //it moves to another activity
            Intent intent1=new Intent (CameraProject.this,INF.class);

            startActivity(intent1);


}
        else {
            //if discard it reopen camera activity
            Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(i, CameraData);
        }

}

    public void exit(View v)
    {
    finish();
}

}

第二类INF.java：显示当前点击的图像，并询问用户输入姓名和电话号码。

public class INF extends CameraProject {
Bitmap bitmap;
String pic,fullPath;
String[] Paths;
int era;
Intent imageReturnedIntent;
final static int CameraData = 0;
ArrayList<Uri> uris;   
File fileIn;


private static final String TAG = "MyActivity";
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.in);

    Button bt = (Button)findViewById(R.id.bt);

    preview();

}
    //to show the image 
private void preview() {
    getLastImageId();
    File imgFile = new  File(fullPath);
    if(imgFile.exists()){

        Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());

        ImageView myImage = (ImageView) findViewById(R.id.imageView1);
        myImage.setImageBitmap(myBitmap);
        //generate toast message
        Context context = getApplicationContext();
        CharSequence text = "image shown clearly or not ,if not than press back";
        int duration = Toast.LENGTH_LONG;

        Toast toast = Toast.makeText(context, text, duration);
        toast.show();


    }

}

public void Takepath(){
    getLastImageId();
    uris = new ArrayList<Uri>();
    Paths = new String[] {fullPath};
    for(String file : Paths ){
    fileIn= new File(file);
    Uri u=Uri.fromFile(fileIn);
    uris.add(u);

    }

}
//perform sending action

        public void sedmail(View v){
            Takepath();
            final EditText et = (EditText)findViewById(R.id.et1);
            final EditText et2 = (EditText)findViewById(R.id.et2);

            Intent i = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
            i.setType("plain/text");
            i.setType("application/octet-stream");

            i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
            i.putExtra(Intent.ACTION_DEFAULT, "test/");

            i.putExtra(Intent.EXTRA_EMAIL, new String[]{"pravind.india@gmail.com"});
            i.putExtra(Intent.EXTRA_SUBJECT, "My Information");
            i.putExtra(Intent.EXTRA_TEXT, "Name:"+et.getText().toString()+'\n'+"Mobile No."+et2.getText().toString());  
            startActivity(Intent.createChooser(i, "send email...."));
        }

//call camera when back button is pressed
    public void cam(View v) {
        finish();
    }


    @Override
    public void onBackPressed() {
    finish();
    Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(i, CameraData);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data){
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            btm = (Bitmap) extras.get("data");

        }
            if(resultCode == RESULT_OK){
                Intent intent1=new Intent (this,INF.class);
                startActivity(intent1);
    }
            else {

                Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(i, CameraData);
            }


    }
        //get the id of the last image taken by camera          
private int getLastImageId(){
    final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
    final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
    Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, null, null, imageOrderBy);
    if(imageCursor.moveToFirst()){
        int id = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID));
         fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
        Log.d(TAG, "getLastImageId::id " + id);
        Log.d(TAG, "getLastImageId::path " + fullPath);
       imageCursor.close();
        return id;
    }else{
        return 0;
    }
}

}

在Android 2.3上工作但在android 4.2上没有
