It should be something easy to do, but these commands return error when I try to convert a String to integer:
Intent recibir = getIntent();
String nombre = recibir.getStringExtra("hora_inicio");
int numero=0;
try {
numero = Integer.parseInt(nombre);
} catch(NumberFormatException nfe) {
nfe.printStackTrace();
}
Toast.makeText(this, numero, Toast.LENGTH_SHORT).show();
Android monitor returns this error:

thanks in advance
The problem is not with your conversion but with your Toast.makeText. When you call Toast.makeText(this, numero, Toast.LENGTH_SHORT).show();
It considers numero as resId and tries to find the relative string resource in strings.xml which fails giving error:
Resources$NotFoundException: String resource ID
Instead of
Toast.makeText(this, numero, Toast.LENGTH_SHORT).show();
DO
Toast.makeText(this, String.valueOf(numero), Toast.LENGTH_SHORT).show();
Try this:
number = Integer.parseInt(YourStringName.toString());
Toast.makeText(this, String.valueOf(numero), Toast.LENGTH_SHORT).show();

MainClass.java
Intent i;
i = new Intent(v.getContext(), Next.class);
i.putExtra("increment1",1);
v.getContext().startActivity(i);
Next.java
Intent mIntent = getIntent();
int age=mIntent.getIntExtra("increment1", 0);
String age1=Integer.toString(age);
Toast.makeText(this,age1, Toast.LENGTH_LONG).show();
When I use variable age in my toast I'm getting below error. That means, I can't use Integer value. Please help me to use the Integer value.

Where i get the error
Pushwoosh.getInstance().registerForPushNotifications();
Duplicating response from Pushwoosh Github here:
This is not a bug of Pushwoosh SDK. This is a peculiarity of multi-processor applications in Android apps environment.
When you integrate analytics tools such as LeakCanary, AppMetrica, and others, these libraries start a new process for itself. A new instance of the app is created In this process. But you do not need to listen for pushes in this separate process, so by default you should not call registerForPushNotifications() inside Application.onCreate().
Therefore there are 2 possible solutions:
Not to call registerForPushNotifications inside Application.onCreate()
If you want to call registerForPushNotifications inside Application.onCreate(), you should perform a check in application's main process:
List < ActivityManager.RunningAppProcessInfo > runningAppProcesses = ((ActivityManager) getSystemService(Context.ACTIVITY_SERVICE)).getRunningAppProcesses();
if (runningAppProcesses != null && runningAppProcesses.size() != 0) {
for (ActivityManager.RunningAppProcessInfo runningAppProcessInfo: runningAppProcesses) {
boolean isCurrentProcess = runningAppProcessInfo.pid == android.os.Process.myPid();
boolean isMainProcessName = getPackageName().equals(runningAppProcessInfo.processName);
if (isCurrentProcess && isMainProcessName) {
Pushwoosh.getInstance().registerForPushNotifications(...);
break;
}
}
}
I now get a new error.
This is my code:
lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int i, long id) {
Toast.makeText(getApplicationContext(), beaconAdap.getItem(i).toString() + " Added to history", Toast.LENGTH_SHORT).show();
historyBeacons.add(beaconAdap.getItem(i).toString());
Intent intent = new Intent(getBaseContext(), HistoryActivity.class);
intent.putStringArrayListExtra("beacons", historyBeacons);
startActivity(intent);
return true;
}
});
}
So i add the int i to an arraylist, i have tested that it goes in and it does. Then a start a new intent for the history activity and send the arraylist over.
This is the code in history:
ListView historyLv = (ListView) findViewById(R.id.historyView);
ArrayAdapter historyAdap;
ArrayList<String> historyBeacons = getIntent().getExtras().getStringArrayList("beacons");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_history);
historyAdap = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_list_item_1, historyBeacons);
historyLv.setAdapter(historyAdap);
}
But i get this error:

The exception happens because your realm variable is null when you call the getAllMovies method.
Remember to call realm = Realm.getDefaultInstance(); previously.
I know this problem so many times asked. and i read every post that made by others here but i cant really solve this problem on my case.
Please help me why this happen and how to fix it ?
this is my code :
public StoreData getStore(String storeid) {
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("select * from " + TABLE_NAME + " where "
+ COL_STORE_ID + "=?", new String[]{storeid});
StoreData data;
System.out.println("This is the problem");
c.moveToFirst();
data = new StoreData(
c.getString(c.getColumnIndex(COL_STORE_ID)),
c.getString(c.getColumnIndex(COL_ACCOUNT_ID)),
c.getString(c.getColumnIndex(COL_KOTA_ID)),
c.getString(c.getColumnIndex(COL_STORE_NAME)),
c.getString(c.getColumnIndex(COL_STORE_MANAGER)),
c.getString(c.getColumnIndex(COL_STORE_ADDRESS)),
c.getString(c.getColumnIndex(COL_STORE_TELEPHONE)),
c.getString(c.getColumnIndex(COL_STORE_GEO_LAT)),
c.getString(c.getColumnIndex(COL_STORE_GEO_LONG)),
c.getString(c.getColumnIndex(COL_STORE_LEADTIME)),
c.getString(c.getColumnIndex(COL_STORE_MD)));
db.close();
c.close();
return data;
}
this is my log :

looks like your query returned 0 results. To check it, don't ignore result of moveToFirst(). It will return false if cursor size is 0.
Do something like this:
if(c.moveToFirst()) {
data = new StoreData(
c.getString(c.getColumnIndex(COL_STORE_ID)),
c.getString(c.getColumnIndex(COL_ACCOUNT_ID)),
c.getString(c.getColumnIndex(COL_KOTA_ID)),
c.getString(c.getColumnIndex(COL_STORE_NAME)),
c.getString(c.getColumnIndex(COL_STORE_MANAGER)),
c.getString(c.getColumnIndex(COL_STORE_ADDRESS)),
c.getString(c.getColumnIndex(COL_STORE_TELEPHONE)),
c.getString(c.getColumnIndex(COL_STORE_GEO_LAT)),
c.getString(c.getColumnIndex(COL_STORE_GEO_LONG)),
c.getString(c.getColumnIndex(COL_STORE_LEADTIME)),
c.getString(c.getColumnIndex(COL_STORE_MD)));
db.close();
c.close();
}
return data;
