I'm creating an Android app to capture image when input the wrong password so I created Camera class & Launcher class:

}
else {
return;
};
} catch (IOException e) {
e.printStackTrace();
f = null;
mCurrentPhotoPath = null;
}
break;
default:
break;
}
startActivityForResult(intent,CAMERA_REQUEST);
mimageView.setVisibility(View.INVISIBLE);
}
private File createImageFile() throws IOException {

String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);

);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
private File setUpPhotoFile() throws IOException {

I am trying to play some rtsp video on custom textureview.Video is playing for the first time but when I go to second activity where the same video is played (not reinstantiated,same session but with different textureview) there it is playing and coming back to first activity where I am setting the sureface again in onResume textureview is still showing the content where it was left for the first time.Interesting fact is like video is still playing, just it is not visible in the textureview and if I go to second screen like before it is showing.I tried both releasing the surfacetexture and not releasing, tried also releasing the surface which I am holding a reference in the first activity for future use, not any of those seems to work.What can be the possible reason?
in onResume I am checking if app is coming back from app drawer or full screen activity.Where making the app go to background by clicking home button and coming back to app from app drawer video is playing.Only when coming back from full screen it's not working.

This is one activity class of my android project and this activity depends on another utility class....which is mentioned below:
The statement Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap(); shows an error in "imageView" and the statement boolean result=userChosenTask.checkPermission(Crime.this); shows an error on "checkPermission"...but I don't understand why...because checkPermission is already defined in the utility class....

In your manifests.xml, you need to include permission:

In my application there is a button to "upload a picture": taking a photo from camera or choosing from gallery.
On both options, there are 3 problems:
1) When clicking again to upload another picture - the application crushes
2) On the first "upload", the picture is rotated on the side (90 degrees counterclockwise)
3) The picture's size is the original size and I want it to be compressed to resolution of 125x125.
Please help (even if you have a solution to one problem)

Use this method to do the compress,just set the targetWidth&targetHeight yourself.
Also,you can use bitmap.compress(Bitmap.CompressFormat.JPEG, compressRate, byteOutputStream); to compress your bitmap by quality.
For the crash,it's because the picture bitmap takes too much memory.You should compress the picture and remember to release the memory after your first upload.You can consider using a WeakReference.

Could someone please help and implement this? I would appreciate and it and it would help a lot. Also, I have even helped myself by trying.
You need to use the TelephonyManager
mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
mTelephonyMgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
The listener object can be created like this
private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
// Test for incoming call, dialing call, active or on hold
if (state==TelephonyManager.CALL_STATE_RINGING || state==TelephonyManager.CALL_STATE_OFFHOOK)
{
stop(); // Put here the code to stop your music
}
super.onCallStateChanged(state, incomingNumber);
}
};
When stopping, or closing your app, remember to call this.
mTelephonyMgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_NONE);
I have tried to get this working so that it plays in the background?? why won't it work it looks fine to me??
I am new to java/android development so hope someone can fix the issue and explain what I problem was so I can learn something
Yes I got it to stream so far but once you exit the app the music stops playing
For being new think im doing great must be since I have previous experience with PHP etc..
Thanks ;)

well, it is stopping because you're asking it to stop.
When the activity goes to background it pauses.
You should run the stream from a service (that stays in the background without issues) and use a bound service to communicate between activity and service http://developer.android.com/guide/components/bound-services.html
