Could not execute method of the activity Android

Question

I have the following button:

    <Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/btn_create_user"
    android:id="@+id/btn_create_user"
    android:onClick="onClickCreateUser"

    android:layout_alignParentBottom="true"
    android:background="@color/btn_create_user"
    android:layout_alignLeft="@+id/btn_login"
    android:layout_alignStart="@+id/btn_login"
    android:layout_marginBottom="23dp"
    android:layout_alignRight="@+id/btn_login"
    android:layout_alignEnd="@+id/btn_login" />

with the following onclick function:

    public void onClickCreateUser(View v){
    Intent i = new Intent("dk.anapp.notebox.activity_createUser");
    startActivity(i);
}

When i press the button i get the following error:

I searched SO but the only answer i could find is for people who forgot to declare the class in the manifest

here is my manifest:

<?xml version="1.0" encoding="utf-8"?>

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="18" />

<uses-permission android:name="android.permission.INTERNET" />

<application
    android:name="dk.anapp.notebox.Mediator"
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="dk.anapp.notebox.Login"
        android:label="@string/title_activity_login" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="dk.anapp.notebox.SoloActivity"
        android:label="@string/title_activity_solo" >
        <intent-filter>
            <action android:name="dk.anapp.notebox.SoloActivity" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name="dk.anapp.notebox.SpashScreen"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/title_activity_spash_screen"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="dk.anapp.notebox.SpashScreen"
        android:label="@string/title_activity_spash_screen" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="dk.anapp.notebox.MyGroups"
        android:label="@string/title_activity_my_groups" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="dk.anapp.notebox.activity_createUser"
        android:label="@string/title_activity_activity_create_user" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

So what am i doing wrong?

Answer 1

in your manifest just do

<activity android:name="dk.anapp.notebox.activity_createUser" />

You should use this <intent-filter> attribute only once, to specify which Activity to run at startup

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Furthermore, change your code to

public void onClickCreateUser(View v){
    Intent i = new Intent(this, Activity_createUser.class);
    startActivity(i);
}

I assumed your activity class is called Activity_createUser.java, if this is not the case you should change the above new Intent(this, Activity_createUser.class); to match with your activity class' name

Answer 2

try this hope this will sort out your problem.

Intent i = new Intent(currentclassname.this,dk.anapp.notebox.activity_createUser.class);
startActivity(i);
