I've tried cleaning my project several times, restarting Eclipse, going to Build path -> Export, making sure Android private libraries is ticked, and I've tried parsing through XML and Java files to find the error myself. I have also tried researching here on StackOverflow but to no avail.
I've also checked if I was calling things before the onCreate
method.
I fear my manifest XML file might be causing an issue but I don't see anything wrong with it.
Also a little information about the project which may help you find the bug:
com.example.myfirstapp
.layout
directory.Since the error is related to the MainActivity XML file, I'll post that and the manifest.
So here's my MainActivity
XML file (file name is 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:background="#800000"
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=".MainActivity">
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/email"
android:layout_centerHorizontal="true"
android:layout_marginBottom="20dp"
android:contentDescription="@+string/logo"
android:src="@drawable/brock_logo"/>
<EditText
android:id="@+id/password"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:ems="10"
android:inputType="textWebPassword"/>
<EditText
android:id="@+id/email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/password"
android:layout_centerHorizontal="true"
android:ems="10"
android:inputType="textWebEmailAddress">
<requestFocus />
</EditText>
<Button
android:id="@+id/login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/password"
android:layout_centerHorizontal="true"
android:layout_marginTop="21dp"
android:onClick="login"
android:text="@string/login" />
</RelativeLayout>
Here is my AndroidManifest
XML file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myfirstapp"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:name=".MainActivity"
android:allowBackup="true"
android:hasCode="false"
android:icon="@drawable/brock_logo"
android:label="@string/app_name"
android:logo="@drawable/brock_logo"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name="com.example.myfirstapp.Schedule"
android:label="@string/app_name"
android:parentActivityName=".MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity"/>
</activity>
</application>
</manifest>
And here is my Logcat

Sorry for dumping code and debug output. Just trying to provide as much information as possible.
Thanks for reading.
try this:
<application
android:allowBackup="true"
android:icon="@drawable/brock_logo"
android:label="@string/app_name"
android:logo="@drawable/brock_logo"
android:theme="@style/AppTheme" >
then clean and rebuild your project.
