How should I define launchMode in AndroidManifest.xml - Using PhoneGap & JQM

Question

I am struggling to restrict my application to a single instance. Currently if the user presses home screen to quit the application, then does something outside and clicks on

Answer 1

Try with

<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:launchMode="singleTop" android:name="HomePage" android:theme="@android:style/Theme.DeviceDefault">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

it's what's generated by phonegap CLI and launchmode set to singleTop to have single instance.

android:name must match the name of the main java class of the activity, not the full package name. By default phonegap sets it as the app name.

This is what ultimately worked for me:

However the trick is that you need to change in two locations:

A) MyAppFolder\platforms\android\AndroidManifest.xml

<activity android:alwaysRetainTaskState="true" android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:launchMode="singleTask" android:name="AppName" android:theme="@android:style/Theme.Black.NoTitleBar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

B) MyAppFolder\www\AndroidManifest.xml

<activity
            android:name="AppName"
            android:launchMode=["singleTask"]
            android:alwaysRetainTaskState="true"
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>

Hope that helps someone.

I struggled with this problem for 2 days. The fix for adding this attribute was only recently added to Cordova as of 3.5, issue CB-6048

add:

<preference name="AndroidLaunchMode" value="singleTask" />

to config.xml

Other available values:

• "standard"
• "singleTop"
• "singleTask"
• "singleInstance"

try this:

<gap:config-file platform="android" parent="/manifest/application">
    <activity android:launchMode="singleInstance" />
</gap:config-file>

but in your config's widget setting, it should be like this (add the android namespace definition):

<widget xmlns     = "http://www.w3.org/ns/widgets"
        xmlns:gap = "http://phonegap.com/ns/1.0"
        xmlns:android = "http://schemas.android.com/apk/res/android"
        id        = "com.wildabeast.app"
        version   = "1.0.0">
....
</widget>
