Usage of getApplicationContext on the sync adapter context

My app includes a sync adapter; it has been working fine for years, but recently I've received a very strange crash report:
Samsung Galaxy S6 Edge+ (zenlte), 4096MB RAM, Android 7.0
java.lang.ClassCastException:
1. at com.myappid.android.ScormApplication.getApplication (ScormApplication.java:34)
2. at com.myappid.android.sync.SyncAdapter.onPerformSync (SyncAdapter.java:98)
3. at android.content.AbstractThreadedSyncAdapter$SyncThread.run (AbstractThreadedSyncAdapter.java:272)
ScormApplication.java:
public class ScormApplication extends Application {
//...
public static ScormApplication getApplication(Context context) {
if (context instanceof ScormApplication) {
return (ScormApplication) context;
}
return (ScormApplication) context.getApplicationContext(); // this is a line 34
}
//...
}
SyncAdapter.java:
public class SyncAdapter extends AbstractThreadedSyncAdapter {
//...
#Override
public void onPerformSync(Account account,
Bundle extras,
String authority,
ContentProviderClient provider,
SyncResult syncResult) {
// sync code here...
ScormApplication.getApplication(getContext()).sendOttoEvent(ottoEvent); // this is a line 98
}
}
Thus, it means that the returned object from the method getApplicationContext called on SyncAdapter's context is not an instance of my application class. But how can it be possible?
Here is a bit more of my code:
AndroidManifest.xml (no separate process is declared) :
<manifest xmlns:android="http://schemas.android.com/apk/res/android" ...>
<application ...>
...
<service
android:name="com.myappid.android.sync.SyncService"
android:exported="true">

<action android:name="android.content.SyncAdapter" />
</intent-filter>
<meta-data
android:name="android.content.SyncAdapter"
android:resource="#xml/syncadapter" />
</service>
...
SyncService.java:
public class SyncService extends Service {
private static SyncAdapter sSyncAdapter = null;
private static final Object sSyncAdapterLock = new Object();
#Override
public void onCreate() {
synchronized (sSyncAdapterLock) {
if (sSyncAdapter == null) {
sSyncAdapter = new SyncAdapter(getApplicationContext(), true);
}
}
}
#Override
public IBinder onBind(Intent intent) {
return sSyncAdapter.getSyncAdapterBinder();
}
}

First, in your metadata, change external-file-path to external-files-path, adding the missing s.
Second, /storage/sdcard0/images1502651207040.png will not match that repaired metadata. The metadata is expecting you to be using getExternalFilesDir(), and specifically a Pictures directory under there. Your path does not resemble that.

According to the documentation:
<external-path name="name" path="path" />
Represents files in the root
of the external storage area. The root path of this subdirectory is
the same as the value returned
byEnvironment.getExternalStorageDirectory().
You are calling a reference from your external storage root (/storage/sdcard0) but you need to reference your package root at /storage/sdcard0/Android/data/your.package.name/Pictures instead.

Android Handler Chain NullPointerException

I'm trying to create communication between Activity - Service - Thread by Handlers. Activity starts a Service that starts a Thread. Thread sends request to the server, waits answer and resend it to Service by Handler (work fine). But when i have try to send message from Service's Handler to Activity app closed with NullPointerException. What am i do wrong?

In conclusion, i deleted Service from my application. Android Service is cancer tumor, threads without benefits. It's just my opinion.

How to pass get text from userinput (edittext) and put into a textview in another activity?

I would like to take user input entered in the EditTextField(in the EnterNewFile class) and put it into the TextField (in the NoteEdit class). Please help! Thanks! FYI- I use XML files for the layouts of these two classes.

mText.getText().toString();

String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);

Take the input from Edittext send it through the Intent to your destination activity and then set it in the TextView there.
I think you seem to already be doing that in your code:
The issue might be the you've not defined in your XML that nextButton function should be call on click ( inside android:onClick: inside your Button).
What you can also do is, in your onCreate funcion set up a listener which listens to the button click and call the intent from within it.
final EditText editText = (EditText) findViewById(R.id.file_name_edittext);
mButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/** Called when the user clicks the Next button */
Log.d("EditText", mText.getText().toString());
Intent intent = new Intent(EnterNewFile.this, NoteEdit.class);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
});
//here you are taking value from EditText and send it to other activity:
Instead of
// Get the message from the intent
Intent intent = getIntent();
String message = intent.getStringExtra(EnterNewFile.EXTRA_MESSAGE);
use following in onCreate() of your other NoteEdit activity:
Intent intent = getIntent();
if((intent.getExtras()!=null) && !intent.getExtras().isEmpty()){
String message = intent.getExtras().getString(EnterNewFile.EXTRA_MESSAGE);
}

this code is working:-
scrollview=(ScrollView)findViewById(R.id.scrollview1);
tb2.setTextSize(30);
tb2.setMovementMethod(new ScrollingMovementMethod());
scrollview.post(new Runnable() {
public void run() {
scrollview.fullScroll(View.FOCUS_DOWN);
}
});
chat1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
{
textsaring1=edt1.getText().toString();
tb2.setText(tb2.getText()+" "+textsaring1);
edt1.setText("");
}
}
});

Application code used to work but now crashes

Thing is my application used to run PERFECTLY but then i wanted to change packages names and classes names so i created another project and copy pasted my code and did the changes there. no error in eclipse but app crashes now !! here's whats my app is about:
public class LocationMobileUser implements LocationListener {
Context gContext;
boolean gps_enabled=false;
boolean network_enabled=false;
public LocationMobileUser(Context gContext){
this.gContext = gContext;

Matcher m = p.matcher(line);
if (m.find()) {
output.append(m.group(1)); // => "isp"
}
} else
lnr.readLine();
}
} catch (IOException e1) {
e1.printStackTrace();

return output.toString();

this app will be exported into a JAR file and then included into another app as a library using build path; and here's what i wrote in this new app:
public class LocationTheApp extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LocationMobileUser LMU = new LocationMobileUser (this);
Location location = LMU.getLocation();
GsmCellLocation CellLocation = LMU.getCellLocation();
String URL = LocationMobileUser.URL;
LocationMobileUser.GetXMLTask xmlp = LMU.new GetXMLTask();
String Provider = LMU.getProvider(location);
String isp = xmlp.getOutputFromUrl(URL);
String latLongString = LMU.updateWithNewLocation(location);
String cidlacString = LMU.CellLacLocation(CellLocation);
String operator = LMU.getSimOperator();
TextView myLocationText = (TextView)findViewById(R.id.myLocationText);
myLocationText.setText("Your current GPS position is:\n" + latLongString);
TextView myprovider = (TextView)findViewById(R.id.myprovider);
myprovider.setText("\nYour GPS position is provided by:\n" + Provider);
TextView myCellLocation = (TextView)findViewById(R.id.mycelllocation);
myCellLocation.setText("\nYour current Cell position is:\n" + cidlacString);
TextView myOperator = (TextView)findViewById(R.id.myoperator);
myOperator.setText("\nYour GSM operator is:\n" + operator);
TextView myispText = (TextView)findViewById(R.id.myispText);
myispText.setText("\nYour current ISP is:\n" + isp);
}
#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;
}
}
Code contains no errors !!
if its any use here's my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.locationmobileuser"
android:versionCode="1"

</application>
Tried to toggle the package name in the Manifest between locationmobileuser and locationtheapp but still app crashes !!
As i said used to work like a charm in my previous projects !!

Any help would be really appreciated !!

see the package name of menifest
package="com.example.locationmobileuser
and activity package name both should be same change this package
<activity
android:name="com.example.locationtheapp.LocationTheApp"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

you need to add empty constructor in your locationmobileuser class.
public LocationMobileUser(){
}

don't need to do all these things , just go to old project and right click on the project ->> refactor to rename project name or package name
