what code would I need to add to be able to use this App on phone? [duplicate]

This question already has an answer here:
NetworkOnMainThreadException with AsyncTask
(1 answer)
Closed 6 years ago.
Would some one tell where and what code I would need to add to my Java file to make my app work using NetworkOnMainThreadException because I am really struggling. App crashed when it starts saying the app has stopped working.

Everything looks fine in your code.
Make sure you have active internet connection in your mobile where you are trying to run this application.
If you are using Internet, then don't forget to add this to your AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>

How can I get my app to read external text file correctly? Only showing weird characters and diamonds

I'm working on my first app. Got everything set up and working correctly, except displaying a random quote from a text file. Clicking the button shows weird characters (diamonds, question marks, etc) and not the actual text except for the placeholder off and on.
I followed the github source correctly as far as I know.

This is what I see:

I had a folder called "fonts" that was not being used. My code was looking for the assets folder with just the randomquote.txt file. Due to the extra folder in there, it was unable to locate the txt file. Deleted the folder since it wasn't being used, saved, boom and progress.

Trying to get a simple Camera application to work

I'm a beginner to Android app development. I'm getting the hang of it, and I've read a lot of tutorials, but I still can't get the camera to work. Basically what I want to do is take a picture, store the image internally within the app and then display that image to (later) be able to draw on it. I'm not worried about the drawing part at the moment because I'm still getting an error for SetOnClickListener...Here's the code.

Simply move this part:
// Add a listener to the Capture button
Button captureButton = (Button) findViewById(R.id.button_capture);
captureButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Camera mCamera = getCameraInstance();
// get an image from the camera
mCamera.takePicture(null, null, mPicture);
}
}
);
into your onCreate() function, at the end of it. Then it should work.
You need to find views / setup click events in the onCreate of Activities.

how to capture image from Camera in Android?

I have made an application to capture photos from the camera.
I have created two Activities: In Activity1 there is one Button which starts the camera wehen it is clicked. When the image is captured, it is passed to Activity2.
However, when I run the application and start the Activity1 (with the one Button) and I click on the button to start the camera it displays a pop up window showing the message "Unfortunately, camera has stopped". There are no errors in the log-cat or on the console.
Can anyone help me. Please. Thanks a lot.

You need only one Activity if you use startActiviyForResult():
Bello, a simple source code for take a picture from camera app, you need to start Activity with startActiviyForResult() and receive the intent from camera application.

out.flush();
out.close();
}
catch (Exception e)
{
Log.e(TAG, "ERROR:" + e.toString());
}
}}}

The steps are:
1. So First of all as before we need to create a static int that will be our
public static final int CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE = 1777;
2. Next we fire intent to start Activity for result:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE);
Here we are actually passing an URI as an extra to the intent in order to save the image at this location when it will be taken.
3. Finally we will receive the result in onActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
//Check that request code matches ours:
if (requestCode == CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE)
{
//Get our saved file into a bitmap object:
File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg");
Bitmap bitmap = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
}
}
When decodeSampledBitmapFromFile method is:
public static Bitmap decodeSampledBitmapFromFile(String path, int reqWidth, int reqHeight)
{ // BEST QUALITY MATCH
//First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
// Calculate inSampleSize, Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
options.inPreferredConfig = Bitmap.Config.RGB_565;
int inSampleSize = 1;
if (height > reqHeight)
{
inSampleSize = Math.round((float)height / (float)reqHeight);
}
int expectedWidth = width / inSampleSize;
if (expectedWidth > reqWidth)
{
//if(Math.round((float)width / (float)reqWidth) > inSampleSize) // If bigger SampSize..
inSampleSize = Math.round((float)width / (float)reqWidth);
}
options.inSampleSize = inSampleSize;
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(path, options);
}
don't forget to add the relevent camera permissions to the manifest file:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

onCreateOptionMenu android Issue

It's the usual activity. The problem is in onCreateOptionMenu. When I click the menu button nothing is done. I don't see where the problem is.
I also try to comment all code without menu but It's still don't work.
It is either a very strange problem or I don't see some simple things..

Help if you see a solution.

You've misspelled method name - it should be onCreateOptionsMenu(), not onCreateOptionMenu().
It's preferable to use #Override annotation to avoid such mistakes:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
This way it will give you compile time error if you misspell method name or use wrong parameters.

Change your onCreateOptionsMenu to:
//Menu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(Menu.NONE, INFO, Menu.NONE, "О программе").setIcon(
R.drawable.info);
menu.add(Menu.NONE, BLOCK, Menu.NONE, "Блокировать").setIcon(
R.drawable.block);
menu.add(Menu.NONE, CLOSE, Menu.NONE, "Выход").setIcon(R.drawable.exit);
return true;
}
It should work now!

try to add
#Override to public boolean onCreateOptionMenu
And do you try to use MenuInflater and inflate menu from xml?
