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[i].setImageDrawable(nonactive_dots);
}
dots[position].setImageDrawable(active_dots);
}
#Override
public void onPageScrollStateChanged(int state) {
}
});
Timer timer = new Timer();
timer.scheduleAtFixedRate(new myTimerTask(), 4000, 2000);
return view;

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

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:

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();
String responseString = "";
Log.d("EpOs", "1");
while (!br.ready());
int i = 0;
while (br.ready()){
Log.d("EpOs", "ln"+i++);
char c;
c = (char)br.read();
if (c != 0)
responseString += Character.toString(c);
}
Log.d("EpOs", "1.5");
System.out.println(responseString);
timestamp = new SimpleDateFormat("E HH:mm").format(new Date());
switch (request) {

SubstituteDay sd = SubstitutePlanGetter.getSubstitutions(responseString)[0];
} catch (URISyntaxException | ImplicitLoginException e) {

break;
}
default: {
returnCode = 2;
}
}
socket.close();
} catch (IOException e) {

}

This is an action what I do :
btUnselectAll.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
// for (RowBean aRowBean_data : rowBeen) {
// aRowBean_data.setSelected(false);
// }
for (RowBean rowBean : Adapter.data) {
rowBean.setSelected(false);
}
adapter.notifyDataSetChanged();
for (ObjectDefExtends objectDefExtends : Singleton.getInstance().getListaODE()) {
objectDefExtends.visible = false;
editor.putInt(objectDefExtends.id.toString(), 0);
editor.apply();
}
}
});
In my App, I save E-Mails with GSON to an .json File. Because of freezing the UI, I've to do this in Background. I tried with a "new Thread" but I got a Parsing-Error of Gson, so I'm trying with AsyncTask now...

My Code worked if I tried to do it on MainThread:
File dir = new File(mailParcel.getContext().getFilesDir() + "/emails/" + mailParcel.getDirectory() + "/" + foldername);
if (!dir.exists()) dir.mkdirs();
for (File f : dir.listFiles()) {
f.delete();
}
String fileName;
File file;
Mail[] Mails = mailParcel.getMails();
for (int i = 0; i < Mails.length; i++) {
fileName = Mails[i].getReceiveDate().toString().replace(" ", "_").replace(":", "-");
try {
file = new File(dir, fileName + ".json");
file.createNewFile();
Writer writer = new OutputStreamWriter(new FileOutputStream(file));
Gson gson = new GsonBuilder().create();
gson.toJson(Mails[i], writer);
writer.close();
}
catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
}
catch (UnsupportedEncodingException usee) {
usee.printStackTrace();
}
catch (IOException ioe) {
ioe.printStackTrace();
}
}
I hope you can help me!
If you have another idea instead of for example doing in Asynctask, tell me please!
The answer is really simple...
I made an AsyncTask instead of the Thread.
Then the code works.
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);

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!
