Im reaching the way how to set image for ImageView from Camera or Gallery without using AlertDialog or handle two buttons for too intent.
So, I found the Intent.createChooser from https://gist.github.com/Mariovc/f06e70ebe8ca52fbbbe2 or Allow user to select camera or gallery for image
Everything working perfect when i was selected image from Gallery, but from Camera , always RunExceptionError.
Here are my classes: MainActivity.class
public class MainActivity extends AppCompatActivity {
private static final int PICK_IMAGE_ID = 234;
ImageView image;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image = (ImageView) findViewById(R.id.imageView);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
onPickImage(v);
}catch (IOException e){e.printStackTrace();}
}
});
}
public void onPickImage(View view) throws IOException{
Intent chooseIntent = ImagePicker.getPickImageIntent(this);
startActivityForResult(chooseIntent,PICK_IMAGE_ID);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,Intent data) {
switch (requestCode){
case PICK_IMAGE_ID:
Bitmap bitmap = ImagePicker.getImageFromResult(this, resultCode, data);
image.setImageBitmap(bitmap);
}
}
}

I had look for "Caused by: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=234, result=-1, data=Intent { }} to activity" but not luck for it, also it may relating to the log selectedImage = NULL.
Please show me any idea or advise for it. Thanks.
