I'm now making a simple android app. It's just allow user to take an Photo and then show it. When i test it in Virtual device, it's ok. But when i download apk to my android device, after i take a photo in Back camera, the app has stopped and return to main menu. Just problem in Back Camera. In addition, in virtual device, after taking photo, the photo will show successfully. But it's empty in my phone
In MainActivity, i click on "Take Photo", it will start the camera and same my image to folder. Then it send the path of Photo to the next activity and show it.
This is my MainActivity
public class MainActivity extends AppCompatActivity {
private static final int REQUEST_ID_IMAGE_CAPTURE = 100;
Button TakePhoto, InsertPhoto, Exit;
String mCurrentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(imageFileName,".jpg",storageDir);
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TakePhoto = (Button) findViewById(R.id.button);
InsertPhoto = (Button) findViewById(R.id.button3);
Exit = (Button) findViewById(R.id.button2);
//Start Camera
TakePhoto.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
System.out.println(ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = Uri.fromFile(photoFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(intent,REQUEST_ID_IMAGE_CAPTURE);
}
}
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_ID_IMAGE_CAPTURE) {
if (resultCode == RESULT_OK) {
//Bitmap bp = (Bitmap)data.getExtras().get("data");
//ByteArrayOutputStream stream = new ByteArrayOutputStream();
// bp.compress(Bitmap.CompressFormat.PNG, 100, stream);
// byte[] images = stream.toByteArray();
File imgFile = new File(mCurrentPhotoPath);
if(imgFile.exists()){
System.out.println("This is file"+mCurrentPhotoPath.toString());
Intent Show = new Intent(MainActivity.this, ShowPhoto.class);
Show.putExtra("image",imgFile);
startActivity(Show);
}
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Action canceled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Action Failed", Toast.LENGTH_LONG).show();
}
}
}
}
This is The ShowPhoto Activity
public class ShowPhoto extends Activity {
private LinearLayout Image;
Button Back,Next;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_photo);
Image=(LinearLayout)findViewById(R.id.linearLayout);
//Get Image from previous Activity
File image = (File)getIntent().getExtras().get("image");
Bitmap bmp = BitmapFactory.decodeFile(image.getAbsolutePath());
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageBitmap(Bitmap.createScaledBitmap(bmp, bmp.getWidth()*2, bmp.getHeight()*2, true));
Image.addView(imageView);
}
}
This is what's in my logcat when i run app enter image description here
