Motorola EMDK implements DataListener crash | Android Studio

Question

I want to implement the DataListener from the Motorola EMDK to my class. If I implement the DataListener my App crashes.

My android Manifest looks like this:

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

<uses-permission android:name="com.symbol.emdk.permission.EMDK" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />

<application

    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <uses-library android:name="com.symbol.emdk" android:required="false"/>


    <activity
        android:name=".Activities.MainActivity"
        android:configChanges="orientation"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <!-- <category android:name="android.intent.category.HOME"/> -->
            <!-- <category android:name="android.intent.category.DEFAULT"/> -->
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

How can I prevent my App from crashing?

I work with the TC55 in Android Studio on a Win PC

I hope you guys can help me

First, be sure to have installed the EMDK runtime on the TC55. This is available on Zebra's support website together with the EMDK v4.0 downloads: EMDK-OSUPDATE-040003.zip.

Then, you can start working with:

<uses-library android:name="com.symbol.emdk" android:required="true"/>

to be sure that the EMDK library is loaded when you're running your app on the TC55.

If you're launching your application at boot time (as the default launcher), you can take a look at the getInstanceAsync so that you can register a callback to be called when the Mx Framework on the device is ready to accept commands.
