Android Activity: Handle Intent after onCreate()?

Android Activity: Handle Intent after onCreate()? - java

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
package com.company.walt.fragments;
public class ManageAccountFragment extends Fragment {
private EditText mName;
private Button mUpdateBtn;
private ProgressBar mProgressBar;
public ManageAccountFragment() {
// 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_manage_account, container, false);
mName = (EditText)view.findViewById(R.id.input_name);
mUpdateBtn = (Button)view.findViewById(R.id.btn_update);
mUpdateBtn.setOnClickListener(new View.OnClickListener()
{

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 ;)

Android: take photo with custom camera activity and return it

I'm using a custom camera class in android. I want to take a photo (only one), finish the activity and return this photo, It doesn't matter if i do this with a bitmap or a bytearray. I'm using an Intent to return the picture.
I have tested 2 ways for do it, but in one way the camera being blocked after take a photo (without exception) and in the other way, in activity result, I can't take the picutre (Bitmap or bytearray) that I have put in the Intent (because it's null)
Here 2 classes, MainActivity and GGCameraActivity (the activity that runs the camera and takes the photo).
MAIN ACTIVITY:
public class MainActivity extends ActionBarActivity{
private static final int CAMERA_ACTIVITY_ID = 98;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b1 = (Button)findViewById(R.id.b_empezar);
b1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
startButtonClick();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_configuracion) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onActivityResult(int reqCode, int resCode, Intent handler){
switch(reqCode){
case CAMERA_ACTIVITY_ID:
if(resCode == RESULT_OK){
//get the byte array
byte[] b = handler.getExtras().getByteArray(GGCameraActivity.PARAM_PHOTO);
//'b' is null.
}
break;
}
}
private void startButtonClick(){
Intent i = new Intent(this, GGCameraActivity.class);
startActivityForResult(i, CAMERA_ACTIVITY_ID);
}
}
CAMERA ACTIVITY:
public class GGCameraActivity extends Activity {
private Activity context;
private GGCameraPreview preview;
private Camera camera;
private ImageView fotoButton;
public static final String PARAM_PHOTO = "bmp";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ggcamera);
context = this;
fotoButton = (ImageView) findViewById(R.id.photo_button);
fotoButton.setOnClickListener(photoButtonClick);
preview = new GGCameraPreview(this,(SurfaceView) findViewById(R.id.ggcameraFragment));
FrameLayout frame = (FrameLayout) findViewById(R.id.ggcameraPreview);
frame.addView(preview);
preview.setKeepScreenOn(true);
}
#Override
protected void onResume() {
super.onResume();
if (camera == null) {
camera = Camera.open();
camera.startPreview();
camera.setErrorCallback(new ErrorCallback() {
#Override
public void onError(int error, Camera mcamera) {
camera.release();
camera = Camera.open();
Log.d("Camera died", "error camera");
}
});
}
if (camera != null) {
if (Build.VERSION.SDK_INT >= 14)
setCameraDisplayOrientation(context,
CameraInfo.CAMERA_FACING_BACK, camera);
preview.setCamera(camera);
}
}
#Override
protected void onPause() {
if (camera != null) {
camera.stopPreview();
preview.setCamera(null);
camera.release();
camera = null;
}
super.onPause();
}
private void setCameraDisplayOrientation(Activity activity, int cameraId,
android.hardware.Camera camera) {
android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(cameraId, info);
int rotation = activity.getWindowManager().getDefaultDisplay()
.getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0:
degrees = 0;
break;
case Surface.ROTATION_90:
degrees = 90;
break;
case Surface.ROTATION_180:
degrees = 180;
break;
case Surface.ROTATION_270:
degrees = 270;
break;
}
int result;
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
result = (info.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else { // back-facing
result = (info.orientation - degrees + 360) % 360;
}
camera.setDisplayOrientation(result);
}
private OnClickListener photoButtonClick = new OnClickListener() {
#Override
public void onClick(View v) {
fotoButton.setClickable(false);
camera.autoFocus(mAutoFocusCallback);
}
};
Camera.AutoFocusCallback mAutoFocusCallback = new Camera.AutoFocusCallback() {
#Override
public void onAutoFocus(boolean success, Camera camera) {
camera.takePicture(null, null, jpegCallback);
}
};
private PictureCallback jpegCallback = new PictureCallback() {
#Override
public void onPictureTaken(byte[] data, Camera camera) {
Intent resultIntent = new Intent();
resultIntent.putExtra(PARAM_PHOTO, data);
context.setResult(RESULT_OK, resultIntent);
context.finish();
}
};
}
NOTE:
I have no errors as exceptions (I mean, the application don't stops cause of an exception), but I have debugged the classes many times and always I think an exception is raised but catched in some place (but not by me) in "Camera.class" (camera class provided by android). I think this because I always enter in a code snippet (in Camera.class) that's to throw an exception. Here this code snippet:
if (msgType!= CAMERA_MSG_PREVIEW_FRAME &&
msgType != CAMERA_MSG_RAW_IMAGE){
throw new IllegalArgumentException("Unsopported message type: "+ msgType);
}
This code snippet is in Camera.class, I always enter it but, if I don't debug the app, just run it (not taking the captured photo from MainActivity) all works well, the app does not crash.
EDIT 1:
I need a custom camera activity, Intent(MediaStore.ACTION_IMAGE_CAPTURE); is not the thing I need.
EDIT 2: I have tested to return a simple integer. I have the same error, the camera blocks after push the button of take photo and never returns to the main activity. Debuggin I can see again the IllegalArgumentException() mentioned above, but app doesn't crash.
Here the code (changes only in callback and onActivityResult for tke integer instead of byte[]):
Callback of takePicture:
private PictureCallback jpegCallback = new PictureCallback() {
#Override
public void onPictureTaken(byte[] data, Camera camera) {
Intent resultIntent = new Intent();
resultIntent.putExtra("int", 5);
setResult(RESULT_OK, resultIntent);
finish();
}
};
onActivityResult in MainActivity
[...]
case CAMERA_ACTIVITY_ID:
if(resCode == RESULT_OK){
int n = handler.getExtras().getInt("int");
}
break;
[...]
EDIT 3: While debugging, I have step into finish method. I have found that this exception is raised:
throw new UnsupportedOperationException(
"startNextMatchingActivity can only be called from a top-level activity");
But, again, the application does not crash.

I have found the problem. I have read that Intents are not very good for handle large objects. I have tested to put a byte[] of 20 components only and there is no problem. But, with the image byte[] (400k size more or less) the app keeps blocked. I have read this things fast and I'm not sure if it's correct 100%.
I have read too that for sharing large objects between activities the best idea is to use static variables (or Parcelables maybe?).
Then when I take the photo, I put it in class with a static varaible and I take it from other activities.
I suppose that the exceptions I was seeing in the debugger (but not thrown) were produced by the fact of put a too large array in the Intent and return it as result (setResult()), but I'm not sure at all.

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

AsyncTask using executeOnExcecutor uses too much memory and cause UI To Freeze

I was instructed to use AsyncTask because multi-threads still caused my application to freeze. I do not believe I am using AsyncTask correctly. In the examples, I saw online, they did not have to call the method Complete().
http://examples.javacodegeeks.com/android/core/os/asynctask/android-asynctask-example/
I call Complete() in the case READ_MESSAGE and as expected it crashes my application. I am not sure what steps I need to take to fix this code. AsyncTask using executeOnExcecutor uses too much memory and cause UI To Freeze. I believe I am calling 'Complete()' incorrectly.

Looks like my initial answer was too short and got converted to a comment :(. As it's actually an answer and not a comment I pasted it once more.
You are creating too many AsyncTasks and the system fails to allocate so many threads. The same question was answered here: java.util.concurrent.RejectedExecutionException: pool=128/128, queue=10/10

RejectedExecutionException you have is caused by the limited capacity of the queue, which keeps waiting tasks (and not by the size of a thread pool).
Default capacity of the queue is 10.
If you want to have more tasks queued run them with executeOnExecutor instead of execute (on android > 3.0):
// create fixed-size thread pool for Executor
private final ExecutorService mThreadPoolExecutor =
Executors.newFixedThreadPool(THREAD_POOL_SIZE);
// then execute your task
task.executeOnExecutor(mThreadPoolExecutor, bool);
In this case queue capacity will be equal to Integer.MAX_VALUE instead of 10 and you won't have tasks rejected (watch out however for not running out of memory submitting too many tasks).
I also recommend renaming your Boolean bool variable, looks very confusing.

Memory not being released when Activity is closed

I have one main activity. It start another sub activities as Tab. On closing sub activities memory isn't released using by sub tab. Memory increases every time on opening other tabs.

Run hprof or another similar profiler. If this is happening, the number of objects of your tab activites will increase. See whats holding onto references to them, and then fix them so they don't.
Its kind of hard to debug this kind of thing without those hprofs.
