InvocationTargetException: Caused by NullPointerException

InvocationTargetException: Caused by NullPointerException - java

My app is crashing. I have errors and I just got done debugging and as the title says thats the problem.
While debugging I found the line that is causing the problem:
listView.setAdapter(arrayAdapter2);
Towards the bottom. I had a similar nullpointerException before here. This time it is different as I am declaring my arrayadapter in the right area. In debugging the result that goes into the array adapter is not NULL.
I have searched the forum and found these:
Why am I getting an InvocationTargetException? Android 2D game
another nullpointerexception
These NullPointerExceptions seem pretty common in android but they are pretty code specific.
In reading the other information correct me if I am wrong the only place the null can be is if the arrayAdapter2 is NULL.

ListView listView = (ListView) findViewById(R.id.listView1);
You're looking in byzipcodepage.xml for a ListView with ID listView1. No such view exists; in fact, there is no ListView in that layout at all.
If you want a list in that view (for the adapter to use), you need to add it; if your ListView is within a different activity, you may need to handle this entire situation a bit differently to pass the data from this activity to that one (perhaps through a Bundle).

App Crashing when calling a Fragment from an Activity

I'm developing an app where I have a fragment as my home page. I'm currently trying to call that fragment from an activity but unfortunately it is crashing. I had even implemented the FragmentTransaction and it still doesnt want to pick it up.

You have declared the fragmentManager and fragmentTransaction but not yet initialized.
FragmentHome fragmentHome = new FragmentHome();
fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.FragmentHolder, fragmentHome);
fragmentTransaction.commit();
Remove this line from onClick method,
CalorieDetails.this.finish();
Because you are going to add the fragment in activity so dont finish the activity.
Add this code in your caloriedetails.xml file
<LinearLayout
android:id="#+id/FragmentHolder"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
Please do some google search before start implement.

Your fragmentTransaction is null as you don't initialize it hence the exception.
Do this
FragmentTransaction fragmentTransaction = getSupportFragmentManager()
.beginTransaction();

I have made an application with a listView, the listView contains text and pictures using an array. I alos have an editText where the user can search through the list using a search functioanlity. The listView loads in fine however when I click on the editView to search through my listView I get an outOfMemoryError. I'm not sure if this has something to do with the size of the images or something. I know questions like this have been asked before however none of them fixed my problem.

java.lang.OutOfMemoryError: Failed to allocate a 36000012 byte allocation with 16777216 free bytes and 21MB until OOM
...
at android.support.v7.widget.AppCompatImageView.setImageResource(AppCompatImageView.java:72)
at saveourcar.soc.CustomListAdapter.getView(CustomListAdapter.java:39)
Your CustomListAdapter is putting a drawable resource in an ImageView. This drawable resource, when decoded and scaled for density, is 36000012 bytes. This is equivalent to a 3000px by 3000px image.
This is much too big. Find out what this resource is and fix it:
Reduce its resolution
If you put it in res/drawable/, move it to a directory that is more indicative of the density you intended that drawable to be used at, and consider having other versions of that drawable, at other resolutions, for other densities
I have also included android:largeHeap="true" in my Manifest file.
Please undo that.

Please help me to solve this issue, i am not able to figure out what is wrong with this code.
Please help for the same.

Just remove xmlns:android="http://schemas.android.com/apk/res/android"
in this line
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
AND
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
You need have at the end :
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />

After struggle a lot for this issue, finally i found that google provides static map in URL.
By using Mapview or fragmentManager will be heavy and app will be slow. so for this better option is to use google static map api.
More details are provided in Android - MapView contained within a Listview and
https://developers.google.com/maps/documentation/staticmaps/
I posted this answer as it may help other.

you can try this line of code in your adapter class for inflating layout
vi = inflater.inflate(R.layout.wall, parent,false);

I think the error is this:
Activity A
i.putExtra("date", dateinput);
and then
Activity B
String dateinput = smashdata.getString("datename");
you call differently to that variable.
My advice would be to use static constants to be free from such errors . :)
Regards.

it seems your string array has problem, check if the string's inside actually have some value of not other wise you will get Null error
String[] info = {nameinput, ageinput, ethnicityinput, hairinput, dateinput, extrasinput};
for now write your info array like this to verify it works
String[] info = new String[]{"nameinput", "ageinput", "ethnicityinput", "hairinput", "dateinput", "extrasinput"};

Create a static ArrayList in A activity add all values in pass this array in ListView adapter
Example:
ArrayList<String>_array = new ArrayList<>();
_array.add(nameinput);
In B Activity
ListAdapter lincadapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, A._array)

Write
String [] info= new String[6];
And then add the values in info={your values};
This might solve your null pointer exception

Button okbutton = (Button) findViewById(R.id.btn_OK);
Button cancelbutton = (Button) findViewById(R.id.btn_Cancel);
final EditText usrname = (EditText) findViewById(R.id.editText1);
final EditText passwd = (EditText) findViewById(R.id.editText2);
Put this in the oncreate method after setContentView(R.layout.activity_main);
and you should be good. You cant do it from that location :)

You should initialize your Views after setting the layout in your onCreate() method.
You are getting the error because you are trying to access the views before setting the layout that is why the application is not able to find the view's id.
Change your code as below:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button okbutton = (Button) findViewById(R.id.btn_OK);
Button cancelbutton = (Button) findViewById(R.id.btn_Cancel);
final EditText usrname = (EditText) findViewById(R.id.editText1);
final EditText passwd = (EditText) findViewById(R.id.editText2);
}

You're trying to find views before your layout is setup. Move
Button okbutton = (Button) findViewById(R.id.btn_OK);
Button cancelbutton = (Button) findViewById(R.id.btn_Cancel);
final EditText usrname = (EditText) findViewById(R.id.editText1);
final EditText passwd = (EditText) findViewById(R.id.editText2);
to your onCreate method. Just after your setContentView call.

First of all you should learn Android life cycle
you should find your all button and edit text in the oncreate method
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button okbutton = (Button) findViewById(R.id.btn_OK);
Button cancelbutton = (Button) findViewById(R.id.btn_Cancel);
final EditText usrname = (EditText) findViewById(R.id.editText1);
final EditText passwd = (EditText) findViewById(R.id.editText2);
}

Initialize you Button and EditText outside the onCreate method like this
Button okbutton;
Button cancelbutton;
EditText usrname;
EditText passwd;
Then insert this
okbutton = (Button) findViewById(R.id.btn_OK);
cancelbutton = (Button) findViewById(R.id.btn_Cancel);
EditText usrname = (EditText) findViewById(R.id.editText1);
EditText passwd = (EditText) findViewById(R.id.editText2);
inside your onCreate method after the setContentView(R.layout.activity_main);
Hope it helps.
