I have written an android app which basically allows me to keep track of times and address of GPS coordinates.
I have 3 Lists each corresponding to Lyft, Uber and Other.
But I believe my app starts slowing down my Smart Phone (Samsung Galaxy S7 Edge, with Android O)
can someone look at my code and tell me why is it slowing my smart phone.
My assumption is that, possibly thread synchronization issue.
Attached is my code

This (likely) isn't a threading issue, in the normal sense of the word. What's happening is you've got a GeoCoder.getFromLocation() call executing on the main thread. Per the documentation:
The returned values may be obtained by means of a network lookup. ...It may be useful to call this method from a thread separate from your primary UI thread.
That means the method could block for several seconds each time it is called. That's more likely if you're driving through an area of spotty cell coverage. Since the method is called with each location update (roughly every 2 seconds), it's understandable that the UI is hanging.
SUGGESTED FIX
Replace your getAddress() function with an AsyncTask, which moves the getFromLocation() call to a background thread (now your app will truly be multithreaded). Something like this should work:
private class GetFromLocationTask extends AsyncTask<Location, Void, List<Address>> {
protected List<Address> doInBackground(Location... locs) {
return gcd.getFromLocation(locs[ 0 ].getLatitude(), locs[ 0 ].getLongitude(), 1);
}
protected void onProgressUpdate(Void... progress) {}
protected void onPostExecute(List<Address> result) {
//execute the remainder of your getAddress() logic here
}
}
Then, execute it using new GetFromLocationTask().execute(location). Call this instead of getAddress(). You don't need to pass a Context to getAddress(), since Service.this will work just as well (it is a Context).
Bonus hint: Note that onLocationChanged() runs on the UI thread, and so does refreshAllViews(). That means your call to runOnUiThread() is superfluous, and it will just execute the given Runnable synchronously.
I am collecting GPS location data in Splash Screen and store it in session, and use it later in MainActivity. If the GPS is turn off or used for the first time it will ask for permission in my splash screen. The problem is that I am using the timer to move splash screen Activity to another activity. Due to the timer, SplashScreen is moving to next the activity without the permission. I want my Splash screen to wait till permission dialog is allowed or denied. Below is my code

If you do not understand please comment.
Try this solution.
First of all, make your onCreate() method this way:
#Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
session = new Session(SplashActivity.this);
//GPS Tracker
permissions.add(ACCESS_FINE_LOCATION);
permissions.add(ACCESS_COARSE_LOCATION);
permissionsToRequest = findUnAskedPermissions(permissions);
//get the permissions we have asked for before but are not granted..
//we will store this in a global list to access later.
welcomeText = (TextView) findViewById(R.id.welcome);
tf1 = Typeface.createFromAsset(getAssets(), "fonts/Roboto-Light.ttf");
welcomeText.setTypeface(tf1);
mLogo = (ImageView) findViewById(R.id.applogo);
zbgimg = (ImageView) findViewById(R.id.zbgimg);
zbgimg.setImageResource(R.drawable.splash_screen_option_three);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (permissionsToRequest.size() > 0)
requestPermissions(permissionsToRequest.toArray(new String[permissionsToRequest.size()]), ALL_PERMISSIONS_RESULT);
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
}
Then make separate setUserLocation() function outside of onCreate() as follow:-
public void setUserLocation() {
locationTrack = new LocationTrack(SplashActivity.this);
if (locationTrack.canGetLocation()) {
double longitude = locationTrack.getLongitude();
double latitude = locationTrack.getLatitude();
Geocoder gcd = new Geocoder(SplashActivity.this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = gcd.getFromLocation(latitude, longitude, 1);
} catch (IOException e) {
e.printStackTrace();
}
if (addresses != null && addresses.size() > 0) {
String locality = addresses.get(0).getLocality();
String subLocality = addresses.get(0).getSubLocality();
String address = addresses.get(0).getAddressLine(0);
String state = addresses.get(0).getAdminArea();
String countryn = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName();
session.setLocation(latitude,longitude,locality,subLocality);
//Toast.makeText(SplashActivity.this,locality +" "+ postalCode + " " + latitude+ " " + longitude,Toast.LENGTH_SHORT).show();
}
startApp();
} else {
locationTrack.showSettingsAlert();
}
}
One more separate function startApp() outside onCreate() like below:-
public void startApp() {
new Handler().postDelayed(new Runnable() {
#SuppressLint("PrivateResource")
#Override
public void run() {
if (session.FbLoggedIn()) {
Intent i = new Intent(SplashActivity.this,
MainActivity.class);
startActivity(i);
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
} else {
Intent i = new Intent(SplashActivity.this,
LoginActivity.class);
startActivity(i);
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
}
}
}, 3000);
}
And last thing, change onRequestPermissionsResult() method like below:-
#TargetApi(Build.VERSION_CODES.M)
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case ALL_PERMISSIONS_RESULT:
for (String perms : permissionsToRequest) {
if (!hasPermission(perms)) {
permissionsRejected.add(perms);
}
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (permissionsRejected.size() > 0) {
if (shouldShowRequestPermissionRationale(permissionsRejected.get(0))) {
showMessageOKCancel("These permissions are mandatory for the application. Please allow access.",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(permissionsRejected.toArray(new String[permissionsRejected.size()]), ALL_PERMISSIONS_RESULT);
}
}
});
return;
}
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
}
else {
animation2();
animation3();
setUserLocation(); //After that start app
}
break;
}
}
So, this solution follow permission first, then user-Location and then startApp.
If I understand correctly you want to access location before going jumping from splash screen. If so just remove timer open and as splash screen opens make it check for location service on/off and get location and then jump to another activity.
if (!canGetLocation()) {
showSettingsAlert();
} else {
fetch location
if (session.FbLoggedIn()) {
startActivity(new Intent(SplashActivity.this, MainActivity.class));
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
} else {
startActivity(new Intent(SplashActivity.this, LoginActivity.class));
finish();
overridePendingTransition(R.anim.entry, R.anim.exit);
}
}
I am android developer .I have face issue ANR when multiple image send in background using intent service.I have call service on Resume() method.I have update UI when step by step image upload finish .My all code in service .But i don't understand why my UI hang.I have created ResultReceiver class for Update UI.

Now your layout:

android:layout_width="fill_parent"
android:layout_height="fill_parent"

<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"

<Button
android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get First File">

<Button
android:id="#+id/Button02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Second File">

/>
<TextView
android:id="#+id/res"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""

</LinearLayout>
of course, include the internet permission in your manifest:
<uses-permission android:name="android.permission.INTERNET" />
And voilà. Anyway i followed this example in my case: http://www.coderzheaven.com/2011/08/16/how-to-upload-multiple-files-in-one-request-along-with-other-string-parameters-in-android/ try to see there.. There are 4 methods to upload multiple files. See which you like

P.S. i have mentioned the permission in manifest.
From your code it seems to be you have not added onActivityResult method. Put the following code in in onActivityResult method
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
Uri contact = data.getData();
ContentResolver cr = getContentResolver();
Cursor c = managedQuery(contact, null, null, null, null);
while(c.moveToNext()){
String id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(Phone.CONTENT_URI,null,Phone.CONTACT_ID +" = ?", new String[]{id}, null);
while(pCur.moveToNext()){
String phone = pCur.getString(pCur.getColumnIndex(Phone.NUMBER));
tv.setText( phone);
}
}
}}
I designed a chat application but if I write text and click on send the application is force closed. I send username, ip and port information to the other activity.
