OutOfMemoryError is the main error , this happens as result of big images sizes in your case results in memory leak.
you can add android:largeHeap="true" and android:hardwareAccelerated="false" in the application tag in the manifest.xml
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="#style/AppTheme">

The problem is with your drawable. Try moving your #dawable/backgto the res/drawable-xhdpi/ folder.

Set all the views on an Activity programmatically

First of all, I'm starting at Android, so maybe I'm asking a stupid question. Oh, and sorry for my English.
I have an Activity that receives an Object when it starts (in the previous activity's Intent) and I want to set severals views (ImageView and TextViews) in the Java file. I have looked for the way to do it, and this is what I think I need.
The XML file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/party"
tools:context=".activities.PartyActivity">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:context=".activities.PartyActivity"
android:id="#+id/head">
<!--Party-->
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/photo"/>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".activities.PartyActivity">
<!--Dia/hora-->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/date"/>
<!--Dirección-->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/currentCity"
android:id="#+id/direction"/>
<!--Precio-->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/currentCity"
android:id="#+id/price"/>
</RelativeLayout>
</RelativeLayout>
<!--Descripcion-->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/head"
android:id="#+id/description"/>
<!--Mapa-->
And this is the class:
public class PartyActivity extends Activity {
private RelativeLayout partyLayout;
private Party party;
private ImageView photoView;
private TextView dateView;
private TextView directionVew;
private TextView priceView;
private TextView descriptionView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_party);
partyLayout = (RelativeLayout)findViewById(R.id.party);
party = (Party)getIntent().getExtras().getSerializable("Party");
setParty();
}
private void setParty(){
partyLayout.removeAllViews();
photoView = (ImageView)findViewById(R.id.photo);
dateView = (TextView)findViewById(R.id.date);
directionVew = (TextView)findViewById(R.id.direction);
priceView = (TextView)findViewById(R.id.price);
descriptionView = (TextView)findViewById(R.id.description);
photoView.setImageBitmap(party.getPhoto());
dateView.setText(Session.getInstance().getDateFormat().format(party.getDate().getTime()));
directionVew.setText(party.getDirection());
priceView.setText(party.getPrice().toString());
descriptionView.setText(party.getDescripcion());
setContentView(photoView);
setContentView(dateView);
setContentView(directionVew);
setContentView(priceView);
setContentView(descriptionView);
}
When I try to go to the activity, the application shuts down. I have debugged it and the Party object has been received correctly, but in the setParty method it throws this exception:

Any help?

As you have already set parent view in onCreate() function.
setContentView(R.layout.activity_party);
Will set the parent layout for the current activity.Which you have already initailzed this in onCreate() function of activity.
All these views(
photoView, dateView, directionVew,
priceView , descriptionView
) are child layouts of activity_party . You don't need to perform setContentView() on these views.
Those views will automatically display your updated data , which you have updated in following line of codes :
photoView.setImageBitmap(party.getPhoto());
dateView.setText(Session.getInstance().getDateFormat().format(party.getDate().getTime()));
directionVew.setText(party.getDirection());
priceView.setText(party.getPrice().toString());
descriptionView.setText(party.getDescripcion());

Since you called partyLayout.removeAllViews(); you removed all views from the layout. That's why findViewById() returns null.

How to solve java.lang.OutOfMemoryError trouble in Android

Closed 6 years ago.
my activity is continuously crashing, this just shows only text on UI, please tell me what I am doing wrong.This is showing error in XML file but according to me the XML file is fine, I am not able to find the bug in XML file.
Here is my code
public class PlacedOrderConfirmation extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.place_order_confirmation);
TextView placed_successful_txt= (TextView)findViewById(R.id.placed_successful_txt);
Intent intent = getIntent();
String edit_order_id = intent.getStringExtra("EDIT_OR_PLACE") != null ? intent.getStringExtra("EDIT_OR_PLACE") : "";
if(edit_order_id!=null && edit_order_id.length()>0){
placed_successful_txt.setText("YOUR ORDER HAS BEEN\nUPDATED SUCCESSFULLY");
}
Button notification_icon = (Button) findViewById(R.id.notification_icon);
ImageView btnContinue = (ImageView) findViewById(R.id.cont);
notification_icon.getLayoutParams().height = (int) (Utility.getDeviceHeight(this) * .04);
notification_icon.getLayoutParams().width = (int) (Utility.getDeviceHeight(this) * .04);
btnContinue.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(PlacedOrderConfirmation.this, ContractorDashboard.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

You set background images to your LinearLayout and Button of your xml. one of those images are giving OutOfMemoryError try reducing size of your image or change it.

You are getting OutOfMemoryError
Thrown when the Java Virtual Machine cannot allocate an object because
it is out of memory, and no more memory could be made available by the
garbage collector.
This error showing when the application attempts to add more data into the heap space area, but there is not enough room for it.
Reduce Image Resolution at first and set android:largeHeap="true" in your manifest .

Problem is in your xml file.
i think clean build should work.

THIS IS THE ERROR I M INCURRING
CODE FOR welcome.java
public class welcome extends AppCompatActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome);
TextView my_msg;
String name;
my_msg= (TextView)findViewById(R.id.textView3);
name= "Welcome " +findViewById(R.id.textView2).toString();
my_msg.setText(name);
}
}
XML CODE FOR welcome.xml ...Please refer it..it only shows the message on screen "welcome Name"..the name is entered by user through activity_form.java
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/textView3"
android:layout_gravity="center"
android:layout_weight="1" />
</LinearLayout>

First the way to solve your exception to type cast the View and getText from that View
(TextView) findViewById(R.id.textView2).getText().toString();
So the final String will look like
name= "Welcome " + (TextView) findViewById(R.id.textView2).getText().toString();
SUGGESTION
Use proper naming conventions for views, Rather than naming view1 view2 etc
