Could-not create the view: org.eclipse.pde.runtime.LogView - android

I am new to Android and building a small test program and the program is not running and giving me Could not create the view: org.eclipse.pde.runtime.LogView error
here is the code from my android_main.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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.myapplication.MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world" />
</RelativeLayout>
Here is the java code from MainActivity.Java
package com.example.myapplication;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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;
}
#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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

I apologize that I am posting this as an answer instead of a comment, but commenting requires 50 reputation and I don't have that yet. Can you post your java code too? The problem is likely in there, it may be the method by which you are loading the view.

Can't really tell what you mean by not working without any log or explanation.
Here are some possible reason:
cannot reach server at url http://localhost:8081/geoserver/NFR-SR/wms
layer name NFR-SR:Ridgeline_SR not found
map service doesn't support application/openlayers
It could even be it is working but you are viewing the map extent which does not contain any data.

Thanks for any help you can provide! ;)
I am not sure try the following:
Add
tools:context= ".MainActivity"
or Can you put <fragment> inside a <FrameLayout>.
Clean the code once.

Just go to your Fragment_navigation class and
replace
import android.app.Fragment;
with
import android.support.v4.app.Fragment;

how to show to battery status on text view?

Actually i am trying to make an android app to display a text when the battery becomes 50% ,m using text view to display the msg,but while loading the app it gets unfortunately stops.
here is my code:
Java file.
package com.example.abhi.batteryalarm;
import android.content.Intent;
import android.os.BatteryManager;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
public class Battery_Alarm extends ActionBarActivity {
Intent batteryStatus;
TextView txtView;
String hello;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_battery__alarm);
txtView=(TextView)findViewById(R.id.txtView);
hello="This is my first project";
int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
if (level==50)
{
txtView.setText(hello);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_battery__alarm, 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);
}
}
activity 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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".Battery_Alarm">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="hello"
android:textSize="62sp"
android:id="#+id/txtView"
android:layout_centerHorizontal="true"
android:layout_marginBottom="125dp" />
</RelativeLayout>
What things i need to do?
Add this,
batteryStatus = registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
before,
int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
and it will work.
This is the line which is causing the error :
int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
It's because the batteryStatus intent is never initialized and is hence null.
Check out this answer about fetching the battery level : https://stackoverflow.com/a/4047790/1239966
You need to register batteryStatus.
IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, ifilter);

Android Layout does not display controls

I am writing my first android app after reading a tutorial. I am excited and thought its easy. However, after adding a simple edit text and a hello world message, i run and was expecting to see something yet nothing showed up. Neither the textbox nor the default hello world. Pls where do go wrong ? Below is my layout (i.e activity_main.xml)
<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:paddingLeft="16dp"
android:paddingRight="16dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:textColor="#FF00FF00"/>
<EditText android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:textColor="#FF0000FF"
android:id="#+id/et_Text" />
</RelativeLayout>
My java code is the default/code generated one. I was expecting to see atleast the message for a start yet didn't show any control. Just a screen with a phone dialers on the rigth hand.
package com.example.mytest;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#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;
}
#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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Since you are using RelativeLayout, you need to tell Android how each control is relative to each other. Change the layout as follow:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:id="#+id/textView1"
android:textColor="#FF00FF00"/>
<EditText android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_below="#+id/textView1"
android:textColor="#FF0000FF"
android:id="#+id/et_Text" />
This will tell the system to place the EditText below the TextView.
