Android : Portrait layout of my app is drawing Views larger on app

I have 2 layouts for the primary screen of a small app I built. One layout is for portrait and one layout is for landscape.

The landscape version looks just how I want it.



Here is the XML code for this layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/gradient"
    android:gravity="center_horizontal|top"
    tools:context=".Main">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"

        <ProgressBar

            android:indeterminate="false"
            android:max="100"
            android:progress="0"
            android:progressDrawable="@drawable/progressbar"
            android:secondaryProgress="100" />

        <ProgressBar

        </LinearLayout>

    </LinearLayout>
</LinearLayout>

The portrait XML is the exact same XML except the top-most LinearLayout has android:orientation="vertical" added to it.

However, when in portrait mode, the progress bars size themselves bigger than the view that contains them.



I suspect this is because half of the screen is not a perfect square, and the View containing the ProgressBar should be a square. Does anyone know how to accomplish my goal here?

Android : App Engine Blobstore Tutorial Server Error

I follow the tutorial of Google about blobstore

https://cloud.google.com/appengine/docs/java/blobstore/#Java_Complete_sample_application

However when i deploy the project to app engine i get the 500 Server Error

these are my classes:

serve class:

import java.io.IOException;
import javax.servlet.http.HttpServlet;

public class Serve extends HttpServlet {
private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();

@Override
public void doGet(HttpServletRequest req, HttpServletResponse res)
    throws IOException {
        BlobKey blobKey = new BlobKey(req.getParameter("blob-key"));
        blobstoreService.serve(blobKey, res);
    }
 }

upload class:

    throws ServletException, IOException {

    Map<String, List<BlobKey>> blobs = blobstoreService.getUploads(req);
    List<BlobKey> blobKeys = blobs.get("myFile");

    if (blobKeys == null || blobKeys.isEmpty()) {
        res.sendRedirect("/");
    } else {
        res.sendRedirect("/serve?blob-key=" + blobKeys.get(0).getKeyString());
    }
}
}

HTTP Sessions are disabled by default. To enable HTTP sessions specify:

It's possible to reduce request latency by configuring your application to
asynchronously write HTTP session data to the datastore:

  <async-session-persistence enabled="true" />

With this feature enabled, there is a very small chance your app will see
stale session data. For details, see

what am i doing wrong ?

Android : Why the App is installed twice?

When I run the Android App Studio, the cell is the App is "installed" twice: There are two apps one called "SplashScreenActivity" and other "Doctor Quiz" (my app), the two are equal. If I uninstall one, the other also uninstalls.

Why does this happen? How do I "install" just my app? (DoctorQuiz)

Android : scene camera not pointing directly at scene

My clipping view isn't aligned in the y-axis. Its like the camera is looking a bit lower than it should be. The x-axis is completely fine, the edge of the scene lines up with the edge of the device screen. I thought that maybe I should rotate the 'mViewMatrix' first but my attempts at that have failed. What should I be doing?

 @Override
    public void onSurfaceChanged(GL10 unused, int width, int height) {

        GLES20.glViewport(0, 0, width, height);// Sets the current view port to the new size.

        float RATIO = (float) width / (float) height;

        Matrix.orthoM(mProjectionMatrix, 0, -RATIO, RATIO, -1, 1, -1, 1);

    }

    @Override
    public void onDrawFrame(GL10 unused) {

        Matrix.setLookAtM(mViewMatrix, 0, 0, 0, -1, 0f, 0f, 0f, 0f, 1.0f, 0.0f);// Set the camera position (View matrix)
        Matrix.multiplyMM(mMVPMatrix, 0, mProjectionMatrix, 0, mViewMatrix, 0);// Calculate the projection and view transformation

Android : How disable scroll movement when i move a bitmap?

I want move a bitmap in the screen, but i can do it only horizontally, because if I do it vertically, the scroll of the view start and the movement of the bitmap disappears. I have

public boolean onTouchEvent(MotionEvent event)

method where in case MOVE I change the X and Y of the bitmap. Then in onDraw() method I paint the bitmap. The scroll are in xml. Inside of it are a layout and inside a View.

I would like when I touch, in case DOWN, if I touch the bitmap, disable the scroll, but I is in other place no.

Can someone help me? Thanks and regards.

Hi All, I am trying to play a song that is in remote server and is in this link. You also can check the song. but as per what i have coded the song is not getting played from the remote server.

Button b = (Button) findViewById(R.id.button1);
    b.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            try{

            mySong = new MediaPlayer();
            mySong.setDataSource("http://www.hrupin.com/wp-content/uploads/mp3/testsong_20_sec.mp3");
            mySong.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mySong.prepareAsync();
            mySong.start();     

            }
