Question

I have been trying to go back to an activity after saving some data. The saving all works find. No errors there and all the streams are closed. Then I try to go back to the MainMenu activity and it seems not to work. Also something that I don’t know if it will effect it but if I created some TextFields in the class do I need to remove them before going to a new activity?

The Code for new activity in (“com.sureclean.versionioo.settings”):

public void onClick(View v) {
        //Saving data code in here
    startActivity(new Intent("com.sureclean.versionioo.MainMenu"));
}

Whole Manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sureclean.versionioo"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".Splash"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainMenu"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="com.sureclean.versionioo.MainMenu" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".checklist"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name=".checklist" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name=".settings"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="com.sureclean.versionioo.settings" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
</application>

Answer 1

If this activity is exists in package defined in manifest …You can write android:name=”.MainMenu”

but if package name is others so write full name

android:name=”yourpackagename.MainMenu”

Use this manifest once

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sureclean.versionioo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".Splash"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".MainMenu"
            android:label="@string/title_activity_main" >
        </activity>
        <activity
            android:name=".checklist"
            android:label="@string/title_activity_main" >
        </activity>
        <activity
            android:name=".settings"
            android:label="@string/title_activity_main" >
        </activity>
    </application>

and in button onclick

startActivity(new Intent(settings.this,MainMenu.class));
