Error saving image from camera(cwac camera)

Error saving image from camera(cwac camera) - android

I am trying to implement the cwac camera library for taking picture and storing them. When i tested the code on htc desire hd there were few complications. This is the screenshot of camera preview.
And when I take picture it shows image preview as.
The codes I have for this are as follows.
This is Activity for implementing camera preview fragment.
public class Camera extends ActionBarActivity implements CameraPreviewFragment.Contract {
private static final String STATE_SINGLE_SHOT="single_shot";
private static final String STATE_LOCK_TO_LANDSCAPE=
"lock_to_landscape";
private static final int CONTENT_REQUEST=1337;
private CameraPreviewFragment std=null;
private CameraPreviewFragment ffc=null;
private CameraPreviewFragment current=null;
private boolean hasTwoCameras=(android.hardware.Camera.getNumberOfCameras() > 1);
private boolean singleShot=false;
private boolean isLockedToLandscape=false;
private Toolbar mToolbar;
private void setToolBar(int toolbarId){
mToolbar = (Toolbar) findViewById(toolbarId);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
getSupportActionBar().setLogo(R.drawable.ic_launcher);
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);
setToolBar(R.id.toolbar);
if (savedInstanceState == null) {
CameraPreviewFragment frag = new CameraPreviewFragment();
frag = CameraPreviewFragment.newInstance(false);
getFragmentManager().beginTransaction()
.add(R.id.container, frag)
.commit();
}
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
setSingleShotMode(savedInstanceState.getBoolean(STATE_SINGLE_SHOT));
isLockedToLandscape=
savedInstanceState.getBoolean(STATE_LOCK_TO_LANDSCAPE);
if (current != null) {
current.lockToLandscape(isLockedToLandscape);
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putBoolean(STATE_SINGLE_SHOT, isSingleShotMode());
outState.putBoolean(STATE_LOCK_TO_LANDSCAPE, isLockedToLandscape);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_menu_camera, 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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean isSingleShotMode() {
return true;
}

And as for the xml layouts I have:

</RelativeLayout>
</LinearLayout>
and for the camera activity I have

<FrameLayout`enter code here`
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar">
</FrameLayout>
</RelativeLayout>
I am using v7 toolbar as the actionbar and is as follows(toolbar.xml)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimaryDark"/>
I tried the demo of the library and is working fine on the same mobile set. Also there seems to be no problem while I was testing it on Nexus 5. I am trying this library for the first time and have no clue for solving this

Android check box tik mark disappear randomly when moving from one fragment to another using android-material-stepper

Instead of getting checkbox like this(i am getting it only few times randomly when moving from on fragment to another).
I am getting like this(checkbox is still true but only tik mark is missing randomly)
I am using onSaveInstanceState and onViewStateRestored. The problem is the checkbox tik mark only disappears and comes back few times but the state of checkbox is still selected i see blue color around all the selected check boxes that selected color doesn't go away only the tik mark goes away and comes back randomly.
Layout:
<?xml version="1.0" encoding="utf-8"?>

Boolean tv = false ;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

//initialize your UI
return v;
}
protected int getLayoutResId() {
return getArguments().getInt(String.valueOf(R.layout.step2));
}
#Override

}
public void onNextClicked(final StepperLayout.OnNextClickedCallback callback) {

}
SharedPreferences shared = getActivity().getSharedPreferences("Mypref", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = shared.edit();
editor.putBoolean("tv", tv);
editor.apply(); // This line is IMPORTANT !!!
callback.goToNextStep();
}
}, 200L);
}
#Override
#UiThread
public void onCompleteClicked(final StepperLayout.OnCompleteClickedCallback callback) {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
callback.complete();
}
}, 2000L);
}
public static StepFragmentTwo newInstance(#LayoutRes int layoutResId) {
Bundle args = new Bundle();
args.putInt(String.valueOf(R.layout.step2), layoutResId);
StepFragmentTwo fragment = new StepFragmentTwo();
fragment.setArguments(args);
return fragment;
}
#Override
public VerificationError verifyStep() {
//return null if the user can go to the next step, create a new VerificationError instance otherwise
return null;
}
#Override
public void onSelected() {
//update UI when selected
}
#Override
public void onError(#NonNull VerificationError error) {
//handle error inside of the fragment, e.g. show error on EditText
}
public void onBackClicked(StepperLayout.OnBackClickedCallback callback) {
//Toast.makeText(this.getContext(), "Your custom back action. Here you should cancel currently running operations", Toast.LENGTH_SHORT).show();
callback.goToPrevStep();
}
}

In short you can do,
#Override
public void onResume() {
super.onResume();
SharedPreferences shared = getActivity().getSharedPreferences("Mypref", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = shared.edit();
tv = editor.getBoolean("tv", tv);
c.setChecked(tv);
}

The app does not crash on runtime, it only displays the map without the RecyclerView. In my gradle file i inlcuded the dependencies i needed. I tried messing around with the gradle file, nothing seems to work. In my logcat I have the following java.io.FileNotFoundException-No such file or directory.

Problem in library de.hdodenhof.circleimageview.CircleImageView. check this
https://github.com/hdodenhof/CircleImageView/issues/121
If you need to circle imageview you can use glide transformation with imageview
https://bumptech.github.io/glide/doc/transformations.html
Example glide v4:
RequestOptions options = new RequestOptions();
options.CircleCrop();
Glide.with(fragment)
.load(url)
.apply(options)
.into(imageView);

Can't change the view depending on the size of the list

I have problem with change view on my layout on my RecycleView.I have list dream. This view contains two state myDreamEmptyLayout witch show Text "For now you don\'t have dream. \n Add dream!" when myDreamList is empty and size is equals 0. But when myDreamList size more than 1 show list dream.
Problem is when have myDream on list and delete all can't show my view myDreamEmptyLayout.
What is problem ?

Your myDreamList will not react to pending changes and as such myDreamEmptyLayout will not get informed of that new information (such as size reached zero) is available. To counter this look at this ObservableArrayList and its OnListChangedCallback. After changing the myDreamList to ObservableArrayList move onResume code (without super of course) to OnListChangedCallback and add this callback via addOnListChangedCallback. This way the changes done to the list will be reflected on the layout as you desire.
The code:
//this goes to onCreate. DISCLAIMER : code written without testing, please confirm that it works.
myDreamList.addOnListChangedCallback(new ObservableList.OnListChangedCallback() {
/*snipped useless methods*/
#Override
public void onChanged(ObservableList<T> sender) {
if (sender.size() == 0) {
myDreamEmptyLayout.setVisibility(View.VISIBLE);
myDreamRecyclerView.setVisibility(View.GONE);
} else {
myDreamEmptyLayout.setVisibility(View.GONE);
myDreamRecyclerView.setVisibility(View.VISIBLE);
}
}
}

I've failed to show lists of a RecyclerView

I am building my first android app using WiFi Direct to transfer
text, image, and media files to peers.I am using a RecyclerView
and a Fragment. I hope to show peers's list on a framelayout
(a simple textview) and then click the views to form a group
to send files. I am stuck at the first stage of making the list shown
on the parent's view. I would appreciate your help on what I did wrong.
I am just a beginner. Any advice or resources would be welcome even besides the pending problem. The followings are three classes and two xmls I've made fumbling around many sources and Android Developer's guide.

I think I have made some (not complete) progress on my question. I suspected that the ArrayList information is not properly delivered to my fragment class. So I wrote the following code in OnCreate method in MainActivity:
DeviceFragment df = new DeviceFragment();
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("bundle",WiFiDirectBroadcastReceiver.peers);
df.setArguments(bundle);
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragment_container);
if (fragment == null) {
fragment = df;
fm.beginTransaction()
.add(R.id.fragment_container, fragment)
.commit();
Log.d (TAG, "fragment_activated");
}
I put the following code in my fragment class:
mDevices = getArguments().getParcelableArrayList("bundle");
and revised Adapter class as follows:
public DeviceAdapter(List<WifiP2pDevice> devices){
Devices=devices;
notifyDataSetChanged();
Log.d (MainActivity.TAG, "device_list");
}
It worked. But I met with one more problem. The textviews on screen are refreshed only when I turned off and on again (not powered on/off). So, I want to make a "refresh button" in MainActivity so that I can refresh the list like when turning on/off. But I have no idea how I can refresh the RecyclerView's fragment in MainActivity. I think I should work on fragmentManager and transaction. Could anybody help me deal with this issue?

Android textview marquee lag

I am trying to implement in my Exo media player a TextView title at the top, with a marquee animation.
As far as I can tell, I have set all the necessary attributes, and it does work, but as the text scrolls, I get a weird lag/the animation stop/restarts. I suspect it has something to do with focus?
What do you think, and do have any idea how to solve the issue?

Just wrapped the text view in a RelativeLayout instead of a LinearLayout, and everything is working as expected.
