When it intent to Activity B, my app will exit automatically. But it will works if the image is captured image. Is it because the size too large? I have no ide on this.Can someone help me? Thanks a lot!
You shouldn't put bitmap into Bundle. The best way is saving image on storage and pass path uri between activities.
byte [] recieve = getIntent().getByteArrayExtra("key",defaultValue);

you can using this method

}
// Create a media file name
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator

}
#Override

Getting Image from Gallery.
Try the following code.Hopefully it will work
public class ImageGalleryDemoActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
}
Taking Picture
public class CameraDemoActivity extends Activity {
int TAKE_PHOTO_CODE = 0;
public static int count=0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//here,we are making a folder named picFolder to store pics taken by the camera using this application
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
File newdir = new File(dir);
newdir.mkdirs();
Button capture = (Button) findViewById(R.id.btnCapture);
capture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// here,counter will be incremented each time,and the picture taken by camera will be stored as 1.jpg,2.jpg and likewise.
count++;
String file = dir+count+".jpg";
File newfile = new File(file);
try {
newfile.createNewFile();
} catch (IOException e) {}
Uri outputFileUri = Uri.fromFile(newfile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}
});
}
#Override

super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Log.d("CameraDemo", "Pic saved");
}
}
}
Also add the permissions in Manifest File:
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Have you got the WRITE_EXTERNAL_STORAGE permission on your manifest file? If not, add

My toast doesn't show up and I am confused because I think I made it correctly, I don't understand. As you can see its a program that shows three buttons, the first one activates a download which is supposed to open the PDFs file automatically - if there is no pdf reader a toast should pop up saying there isn't a reader. the other buttons take to a new screen and operate as a back button.

The above code show toast only if you have not declared the activity in your manifeast file but not when the pdf is not present. You must use FileNotFoundException for your requirement.
