}
Beginning with startButton.onclick() a system? permission dialog is shown as a result of calling startActivityForResult(mProjectionManager.createScreenCaptureIntent(), REQUEST_CODE);.
Then, the user either accept or decline the permission request. Therefore closing the permission dialog.
After that, we receive a callback of this action onActivityResult() with the REQUEST_CODE. We could use this opportunity to call something, but this is not really helpful since our goal is to fetch the first image that is clear of the dialog. After the callback, the dialog is starting to fade.
Now, if the permission was granted, dirty Image(s) now start being dispatched to the now registered ImageAvailableListener.onImageAvailable(...).
We receive an Image immediately after the user accepted. But the first few frames, after the callback, are dirty by showing a fading permission dialog. Is there a way to get a reference of this permission dialog so that we know exactly when it is no longer visible on screen?
A quick hack would be to add a delay to allow for the dialog box to disappear. Or skip the few dirty frames to get the first clean image...

i also make sure that my android manifest is correct
I have Spent Day and Night trying to solve this problem, Browsed through numerous pages on the topic, Tried different codes of my own.
And it still happens. I am a beginner in Android. And please, please do help me. Is there no possible way to solve my problem?
this is my logcat
LogCat

Firstly, you should include your logcat in text form as a part of your question!
However, from what I can read from your screenshot the issue is in the onLocationChanged() method. Perform a check on "location" to see if it is null before trying to read it.
#Override
public void onLocationChanged(Location location) {
if(location != null){
double longitude = location.getLongitude();
double latitude = location.getLatitude();
textView.setText("Longitude:" + longitude + "\n" + "Latitude:" + latitude);
}
else{
Log.e(TAG, "onLocationChanged -- location is null!");
}
}
Note:
Just in case you didn't know the "TAG" is generally added to the beginning of most Android class like this:
public class MainActivity extends AppCompatActivity implements LocationListener {
private static final String TAG = MainActivity.class.getSimpleName();
Why MainActivity.class.getSimpleName() instead of just "MainActivity"? Because if you ever refactor your code, then the name will automatically be changed.
EDIT:
Have you added the necessary permissions in your manifest file?
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-feature android:name="android.hardware.location.gps"/>

Sending image from Android to PHP

I have tried 3 diffrent methods for sending a image from my Android to PHP.
All three gives the message "Missing inp_image name". I am thinking that I maybe am not sending the image as an image, but rather as some text ?
I am using this http request class in Android: https://github.com/kevinsawicki/http-request
Method 1 with encoding it to base64:
//String selectedFilePath = FilePath.getPath(context, imageUri);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
Bitmap bm = BitmapFactory.decodeFile(destImage,options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,40,baos);
byte[] byteImage_photo = baos.toByteArray(); // bitmap object
//generate base64 string of image
String encodedImage = Base64.encodeToString(byteImage_photo,Base64.DEFAULT);
// Send image
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", encodedImage);
stringResponse = request.body();
Method 2 - sending a input stream of image
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", in); // sending input stream
stringResponse = request.body();
Method 3 - sending file:
String sourceFilename= FilePath.getPath(context, imageUri);
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", new File(sourceFilename)); // sending input stream
stringResponse = request.body();

Instead of using only
File myDir = new File(sdCard, "Video/CrazySing");
use
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Video" + n + ".mp4";
File file = new File(myDir, fname);
This will generate a unique file name for each time.
Instead .mp4 you can use your video extension

You're not reusing your list items. This is why the list is starting to "stutter".
There are a lot of answers on this problem that display the concept of reusing ListView items.
Like this one
In general: within your getView method, check if the convertView is null. If it is, inflate your view. If it's not null, just insert the items that you want to display. This should solve your stuttering list view problem.

Please use for existing layout in BaseAdpter as below
ViewHolder holder = null;
if ( convertView == null )
{
/* There is no view at this position, we create a new one.
In this case by inflating an xml layout */
convertView = mInflater.inflate(R.layout.listview_item, null);
holder = new ViewHolder();
holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
convertView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) convertView.getTag ();
}
this may helps you
