Java Android - Either there is not enough memory for the backgroud task or there's a problem with the GC

My android app is supposed to read about 25kb from a InputStream which is wrapped in a BufferedReader. This happens in a background Thread that communicates via a Handler. But when starting to read the Thread seems to be blocked and a debug message shows up:
09-29 22:56:27.837 13625-13640/de.jzbor.epos I/art: Background sticky concurrent mark sweep GC freed 519353(7MB) AllocSpace objects, 0(0B) LOS objects, 77% free, 2MB/10MB, paused 797us total 109.196ms
I don't know how to handle or bypass it and I wasn't able to find something useful on the internet. I would be very thankful for any tipps or solutions.
Here is the code and the log:

if ((networkInfo == null) || (!networkInfo.isConnectedOrConnecting())) {
returnCode = 1;
} else {
try {
socket = new Socket(HOST, PORT);
PrintWriter pw = new PrintWriter(socket.getOutputStream());
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
pw.println("get " + request);
pw.flush();

}
socket.close();

The Garbage collection is slowing down my application running?

Here is the Fragment I am running, It used for running an if statement with dots, every time the image moves. As well as this theres an automatic timer where the images moved based on a time that I set. The app worked well until I added in the dots feature. It is still working but very slowly and cuts out of maybe 2/3 minutes of it running. Is there parts of this code I can change or delete or can I run the app on external memory? mayeb this would speed it up a bit. Ive tried to set the drawables as local variables but still no change. Is there anything else I can do.
public class HomeFragment extends Fragment {
ViewPager viewPager;
ViewPagerAdapter adapter;
LinearLayout sliderDotsPanel;
private int dotsCount;
private ImageView[] dots;
Drawable active_dots;
Drawable nonactive_dots;
public HomeFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home, container, false);
viewPager = (ViewPager) view.findViewById(R.id.view_pager);
sliderDotsPanel = (LinearLayout) view.findViewById(R.id.SliderDots);
active_dots = getDrawable(getActivity().getApplicationContext(), R.drawable.active_dot);
nonactive_dots = getDrawable(getActivity().getApplicationContext(), R.drawable.nonactive_dot);
adapter = new ViewPagerAdapter(this.getActivity());
viewPager.setAdapter(adapter);
dotsCount = adapter.getCount();
dots = new ImageView[dotsCount];
for (int i = 0; i < dotsCount; i++) {
dots[i] = new ImageView(getActivity());
dots[i].setImageDrawable(nonactive_dots);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(8, 0, 8, 0);
sliderDotsPanel.addView(dots[i], params);
}
dots[0].setImageDrawable(active_dots);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
for (int i = 0; i < dotsCount; i++) {

}
dots[position].setImageDrawable(active_dots);
}
#Override
public void onPageScrollStateChanged(int state) {
}
});

Delete the while (true) { just before the loop. works fine now

App stopped working Android Studio

How many activities can I put in my project how many pictures? I make one project and have now 13 activities also and when I have between 5 and 8 activities, my project works wonderfully. Nothing stacks, nothing crashes and now I have 13 activities and when I build my project and open it, the welcome screen works and I can open one, two or three other activities but on 4 or 5 activities open and my app stops working and crashes. I think it is out of memory, but I don't understand why it happens because I have all of my bitmaps resized and compressed and when I start a new activity after startActivity() I put finish().

AFAIK 13 activies are supported so i guess the problem is somewhere else..maybe you did not give enough ram to your AVD.
Anyway i feel to adivice you to use fragment.

Try this may help you add this tag in your manifest file.
<application
...
...
android:largeHeap="true"
......
......
</application>
it will allocate large heap for your app
Or try this
May cause this. For creating Bitmaps memory-efficient you should use BitmapOptions
Bitmap bm;
bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile(filepath),100, 100, true);
mPicture = new ImageView(context);
mPicture.setImageBitmap(bm);
check this Strange out of memory issue while loading an image to a Bitmap object

Android MultiThread SpeedTest have performances problems

I've started to do a speedtest application recently.
The method is simple :
I instanciate multiple threads all downloading the same uncompressible file, then i calculate the average download speed.
But I've got some performances problems I think. When i start the test with more than one thread, i see a lot of GC_CONCURRENT freed and WAIT_FOR_CONCURRENT_GC in the logCat.
I don't understand where's that comming from.
Habitually these problems seems to appear in certain circumpstances, like instanciating too much objects, or huge objects, but i don't think it's the case here...
Here is my code (simplified - without speed calculation):
public class SpeedTest extends Activity{
private final int NB_THREADS = 2;
private long bytesIn;
private long downloadTime;
private List<Downloader> downloaders = new ArrayList<Downloader>();
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.speed_test);
bytesIn = 0;
for (int i = 0; i < NB_THREADS; i++){
downloaders.add(new Downloader());
downloaders.get(i).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, i);
}
}
private synchronized void addBytes(){ bytesIn++; }
private class Downloader extends AsyncTask<Integer, Void, Void>{
#Override
protected Void doInBackground(Integer... params){
Log.d("eduine", "Downloader " + params[0] + " started");
try{
InputStream stream = new URL("http://test-de-vitesse.ariase.com/ariasetool/1mb_random.bin").openConnection().getInputStream();
while((stream.skip(1)) != 0){
addBytes();
}
stream.close();
}catch (MalformedURLException e){
e.printStackTrace();
Log.e("eduine", "malformed url : " + e.getMessage());
}catch (IOException e){
e.printStackTrace();
Log.e("eduine", "io error : " + e.getMessage());
}
Log.d("eduine", "Downloader " + params[0] + " terminated");
return null;
}
}
}
So I'd like to know if someone already experienced this problem, or have any idea why is there these performances problems, because it distorts the speed calculations.
Thanks in advance!

Thread objects themselves consume much memory for their stacks. To clean your test from instantiate/free threads, do not use AsyncTask (which creates Thread), but create a fixed threadpool beforehand, start test, wait it to end, and only then shutdown the thread pool.

Thread OutOfMemoryError, Force Close

everytime I run this code I get a force close, which i don't understand. Im new to Android development, can anybody help? I'm really thankful for any tips from you guys. So far i just understood, that the memory space is running out, but how can I prevent the memory from running low?
