Android could not lock surface when puting shared preferences

Very strange thing. I found out that when I do spEditor.putBoolean("closePxCmInfo", false).apply(); then an error occurs like that:

Help me please!

Android Activity: Handle Intent after onCreate()?

I have a problem with the order in which my Android Activity is intitialized.
Basics:
The Activity contains a ViewPager with contains 3 Fragments. The Activity is opened this way:
Intent foodsActivityIntent = new Intent(getActivity(), FoodsActivity.class);
foodsActivityIntent.putExtra("NavigationPosition", navigationPosition);
foodsActivityIntent.putExtra("SearchQuery", searchQuery);
foodsActivityIntent.putExtra("SelectedDateMillis", _currentDay.toDate().getTime());
startActivityForResult(foodsActivityIntent, 200);
In the onCreate - Method i catch the Intent and do some stuff:
Intent intent = getIntent();
if (intent != null) {
//Some stuff
_foodsPagerAdapter.performSearch();
}
The interesting part here is "_foodsPagerAdapter.performSearch()". With this i want to perform a search in each Fragment.
public void performSearch() {
if (_foodSearchFragment != null)
_foodSearchFragment.performSearch();
if (_foodFavoritesFragment != null)
_foodFavoritesFragment.performSearch();
if (_foodCustomFragment != null)
_foodCustomFragment.performSearch();
}
The Problem:
As you can see, the search method in each Fragment is only called if the Fragment is not null. My problem is that the getItem() - Method(which initializes the Fragments in the Adapter) is called after the onCreate (and onStart) Method finished. So the performSearch - Method for each Fragment is never called.
You can understand this better with this Logcat output:
First performSearch is called and then getItem(). But getItem must be called first for my code to work.
getItem():
#Override
public Fragment getItem(int i) {
Log.i("FoodActivityTest", "call getItem in FragmentPagerAdapter");
Fragment fragment = null;
switch (i) {
case 0:
if (_foodSearchFragment == null)
_foodSearchFragment = new FoodSearchFragment();
fragment = _foodSearchFragment;
break;
case 1:
if (_foodFavoritesFragment == null)
_foodFavoritesFragment = new FoodFavoritesFragment();
fragment = _foodFavoritesFragment;
break;
case 2:
if (_foodCustomFragment == null)
_foodCustomFragment = new FoodCustomFragment();
fragment = _foodCustomFragment;
break;
}
return fragment;
}
What am I doing wrong? Do I need to approach the problem differently?
EDIT 1:
FoodsActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_foods);
//Init some views
_viewPager = findViewById(R.id.viewpager_foods);
_foodsPagerAdapter = new FoodsPagerAdapter(getSupportFragmentManager(), this);
_viewPager.setAdapter(_foodsPagerAdapter);
handleOpenIntent();
//do more stuff (show ads etc.)
Log.i("FoodActivityTest", "onCreate finished");
}
#Override
protected void onStart() {
super.onStart();
Log.i("FoodActivityTest", "onStart finished");
}
private void handleOpenIntent() {
Intent intent = getIntent();
if (intent != null) {
int navigationPosition = intent.getExtras().getInt("NavigationPosition");
String searchQuery = intent.getExtras().getString("SearchQuery");
_viewPager.setCurrentItem(navigationPosition);
_foodsPagerAdapter.performSearch(searchQuery);
}
}
EDIT 2:
FoodsPagerAdapter:
public class FoodsPagerAdapter extends FragmentPagerAdapter {
private Context _context;
private FoodSearchFragment _foodSearchFragment;
private FoodFavoritesFragment _foodFavoritesFragment;
private FoodCustomFragment _foodCustomFragment;
public FoodsPagerAdapter(FragmentManager fm, Context context) {
super(fm);
_context = context;
}
#Override
public Fragment getItem(int i) {
Log.i("FoodActivityTest", "call getItem in FragmentPagerAdapter");
Fragment fragment = null;
switch (i) {
case 0:
if (_foodSearchFragment == null)
_foodSearchFragment = new FoodSearchFragment();
fragment = _foodSearchFragment;
break;
case 1:
if (_foodFavoritesFragment == null)
_foodFavoritesFragment = new FoodFavoritesFragment();
fragment = _foodFavoritesFragment;
break;
case 2:
if (_foodCustomFragment == null)
_foodCustomFragment = new FoodCustomFragment();
fragment = _foodCustomFragment;
break;
}
return fragment;
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return _context.getString(R.string.activity_foods_search);
case 1:
return _context.getString(R.string.activity_foods_favorites);
case 2:
return _context.getString(R.string.activity_foods_customfood);
default:
return "Error";
}
}
public void performSearch(String query) {
Log.i("FoodActivityTest", "call performSearch");
if (_foodSearchFragment != null)
_foodSearchFragment.performSearch(query);
if (_foodFavoritesFragment != null)
_foodFavoritesFragment.performSearch(query);
if (_foodCustomFragment != null)
_foodCustomFragment.performSearch(query);
}

You should be able to pull the values out of your intent before you initialize the other objects. From the looks of it currently, you are trying to populate an view with no data, then assign the data later. To solve, you could either better handle the null in your adapter, or move your data assignment. I would probably do the latter.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_foods);
// Added this. Moved part of handleOpenIntent() here, other half is below view init.
String searchQuery = "";
Intent intent = getIntent();
if (intent != null) {
int navigationPosition = intent.getExtras().getInt("NavigationPosition");
searchQuery = intent.getExtras().getString("SearchQuery");
//should probably have some error handling if the SearchQuery is missing or the value is invalid.
}
// End of additions
//Init some views
_viewPager = findViewById(R.id.viewpager_foods);
_foodsPagerAdapter = new FoodsPagerAdapter(getSupportFragmentManager(), this);
_viewPager.setAdapter(_foodsPagerAdapter);
// added this too, moved out of handleOpenIntent()
_viewPager.setCurrentItem(navigationPosition);
_foodsPagerAdapter.performSearch(searchQuery);
// end of additions
//removed
//handleOpenIntent();
//do more stuff (show ads etc.)
Log.i("FoodActivityTest", "onCreate finished");
}

Progressbar is not displaying in fragment

I have created a Firebase application.
Everything so far is working great. I have one issue, however, that I'm unable to fix.
My MainActivity.java is implementing an Interface ProgressDisplay.java
The Interface has two methods:
public interface ProgressDisplay {
public void showProgress();
public void hideProgress();
}
I'm not able to call these 2 methods from sub fragments, I'm unable to set the visibility on and off in the fragments.
ManageAccountFragment.java

I don't know why this is not working, am I doing something wrong?

I think its because of this lines of code
findViewById(R.id.progressBar).setVisibility(View.INVISIBLE);
Just instantiate your Progressbar in your main Activity onCreate(){HERE} and use mProgressBar in the Hide and Show functions
public void showProgress() {
mProgressBar .setVisibility(View.VISIBLE);
}
I Hope this helps ;)

Keep Activities in stack, but return only to the main

I have nine activities. For example, Activity "A" is the main. The user opens from the NavigationDrawer the Activity "B", "С", "D" and in "D" he clicks on the "back" button. In this case, need to return to Activity "A" and not pass through the entire stack of recently opened activities.
This code does what I need:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Handler mHandler = new Handler();
drawerLayout.closeDrawers();
switch (item.getItemId()) {
case R.id.A:
if (item.isChecked()) {
break;
} else {
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, A.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
case R.id.B:
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, B.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
case R.id.C:
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, C.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
case R.id.D:
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, D.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
case R.id.E:
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, E.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
case R.id.F:
File usersCounter = new File("data/data/com.com.com/shared_prefs/file.xml");
if (usersCounter.exists()) {
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, F.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
} else {
if (item.isChecked()) {
break;
} else {
if (activity instanceof A) {
userFlavorsMap.clear();
if (flavorContainer.getChildCount() > 0){
flavorContainer.removeAllViews();
}
}
mHandler.postDelayed(new Runnable() {
#Override
public void run() {
intent = new Intent(activity, G.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
activity.startActivity(intent);
}
}, 250);
}
break;
}
}
return false;
}
But, if user switched to Activity, for example, "C" and folded the application, then after return to app will open "A". How can I complete the code so that when I return to the application, it open the last opened Activity, but all the recent activities are not going to be in the stack?
In manifect android:launchMode="singleTop"

try this in each activity except MainActivity
#Override
public void onBackPressed() {
super.onBackPressed();
Intent mainIntent = new Intent(YourCurrentActivityName.this,MainActivity.class);
startActivity(mainIntent);
finish();
}

Cannot parse "#" sign in dialer

I'm making a custom dialer and everything till now was perfect. Now while testing, I saw that the "#" sign was not working properly. It shows on the dialer but while calling, it goes away. For eg, if I dial *121#, it becomes *121 when the call is being made through the stock dialer. Here is the code for my activity-
public class DialPadActivity extends Activity {
private EditText numberField = null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initializeButtonArrowClickListeners();
}
public void dialButtonClick(View v) {
int buttonId = v.getId();
putNumberToEditText(buttonId);
}
public void buttonPhone_click(View v) {
if (numberField != null) {
String phone = numberField.getText().toString();
String uriString = "tel:" + phone;
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(uriString));
startActivity(intent);
}
}
public void putNumberToEditText(int buttonId) {
switch (buttonId) {
case R.id.dial_button0:
putNumber("0");
break;
case R.id.dial_button1:
putNumber("1");
break;
case R.id.dial_button2:
putNumber("2");
break;
case R.id.dial_button3:
putNumber("3");
break;
case R.id.dial_button4:
putNumber("4");
break;
case R.id.dial_button5:
putNumber("5");
break;
case R.id.dial_button6:
putNumber("6");
break;
case R.id.dial_button7:
putNumber("7");
break;
case R.id.dial_button8:
putNumber("8");
break;
case R.id.dial_button9:
putNumber("9");
break;
case R.id.dial_button_s:
putNumber("*");
break;
case R.id.dial_button_p:
putNumber("#");
break;
}
}
public void putNumber(String number) {
if (numberField == null) {
numberField = (EditText) findViewById(R.id.phone_number_field);
}
numberField.append(number);
}
private void initializeButtonArrowClickListeners() {
ImageButton buttonArrow = (ImageButton) findViewById(R.id.button_arrow);
buttonArrow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (numberField != null && numberField.length() > 0) {
String previousNumbers = numberField.getText().toString();
String numbersMinusTheLast = previousNumbers.substring(0,
numberField.length() - 1);
numberField.setText(numbersMinusTheLast);
}
}
});
buttonArrow.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
if (numberField != null) {
numberField.setText("");
}
return false;
}
});
}
Where am I doing the wrong?

Use URLEncoder.encode(string, "UTF-8");
For example:
String uriString = "tel:" + URLEncoder.encode(phone, "UTF-8");

Replace your # symbol with %23.
That is: *121%2311 instead of *121#11
String uri = "tel:" + "*6133%235345";
Intent intent;
intent = new Intent(Intent.ACTION_CALL, Uri.parse(uri));
startActivity(intent);
the output for this is : *6133#5345
